I would say 10 to 50 watts on 2M/70cm and then the maximum which I think is 5 watts on 23 cm (if that too is supported). Also, features for satellite comms too would be nice. And maybe a full 1.5 KW linear amplifier for 2 meters too ? OK, just kidding, I am happy with 10 watts. 73, phil, K7PEH From gm3sek at ifwtech.co.uk Sat Apr 1 02:03:31 2017 From: gm3sek at ifwtech.co.uk (Ian White) Date: Sat, 1 Apr 2017 07:03:31 +0100 Subject: [Elecraft] Wanted: XV-432 transverter In-Reply-To: <007101d2a9f1$c48d9030$4da8b090$@co.uk> References: <007101d2a9f1$c48d9030$4da8b090$@co.uk> Message-ID: <003001d2aaad$b5f9b230$21ed1690$@co.uk> >After many years away from 432MHz, I'm feeling the urge to come back to >the band. > >Does anyone on the list have an XV-432 that is gathering dust? > Thank you, a deal has been done! 73 from Ian GM3SEK From john at kn5l.net Sat Apr 1 07:33:03 2017 From: john at kn5l.net (John Oppenheimer) Date: Sat, 1 Apr 2017 06:33:03 -0500 Subject: [Elecraft] KX2 MENU:TIME Feature Request Message-ID: <43e03b0a-4d75-2abb-e179-b9478b46dd56@kn5l.net> Hi Wayne, I'd like a change which sets seconds to zero when tapping the 3 button?

I thought it was an intermittent antenna problem, then switched to it being an SWR measurement problem. I tried everything including two updates of firmware which had temporary benefit but didn't last. Wrote to Elecraft and carried out all checks they recommended except (to my embarrassment) for one which I thought unlikely. There is a lesson here!! Yes, it did turn out to be the real cause and that was to check and tighten the three screws on the bottom cover for the LPA transistors (p63 in assembly manual). My assumption now is therefore that loose mountings / grounding may have been causing erratic reactive components in the LPA power circuitry leading to sprogs which trigger the much improved VSWR sense circuitry to hunt but never actually find a stable point except when on steady tune up carrier. Incidentally it didn't show up when running low power (10W) using the LPA only. It is so easy to jump to the wrong conclusions; in this case where improvements in the SWR sense loop performance was masking the growing problem with poor ground of key LPA components. After re-reading the Elecraft advice again I did actually check the screws (they were very loose) and tightened them up it all went back to normal. Disconnecting the cables from the K3 to connect to the PC for the firmware uploads must have temporarily disturbed the seating of the LPA screws giving a false and temporary indication of a fix. A regular ragchew contact reported much cleaner rf signal as seen on a pan display after the repair.

That is, of course, a dream even for high efficiency switch-mode amps. There are several unique characteristics with SS amps. They are truly different that that trusty and rugged old dual 3-500 Amp. First, the power supply. You can use a linear power supply, big transformer etc. You can even regulate it if you like. Most good transistors run in 50 VDC. But this approach gets you back to that 75 pound transformer. Switch mode power supplies at 50v 60-80 A are easily possible with today's technology. But it also means that you will need PFC if you don't want to pop your breaker every time you tune up. Efficiencies in the area of 85-90% are common for PFC + SMPS. You can do better at higher cost. The amp itself is likely to achieve 55-60% efficiency depending on where you set the bias for AB2 operation and your actual operating conditions. Note that this number varies with several factors including temperature. Then there is SWR. Remember that Drake L4B amp has a tunable matching network at the output that acts like an RF matching transformer to match the tube output impedance (K-ohms) to whatever antenna impedance you have. It can tolerate a wide range of impedance --maybe 2:1 or even 3:1. This means that the 1500 W of RF power is efficiently sent down the coax--mismatch is handled. In the case of a solid state amp, the output is matched to 50 Ohms or so. Period. So any mismatch means that RF is reflected back into the amp....where it is converted into heat. Depending on your SWR, that could be substantial! So let's say 3:1. Then 25% of the power is reflected. Note: at 10:1 you reflect 67% of the power so that means 500 W reaches your antenna and 1000W is dissipated in the Drain-Source junctions of your expensive RF transistors! So let's look at it this way. You put out 1500 W Amp efficiency is 60% = 1000w dissipated Power supply = 87% = 374 W dissipated Reflected at 3:1. 375 W Total 1749 watts Go turn on that 1500 W space heater to see what this feels like! The design is almost more of a thermodynamic challenge than an RF challenge!!!

If the matching range is extended to the 10 : 1 SWR range then the components will be *quite* large.

That antenna presents a load of about 5 ohms -J500 and the coupler will have to be large at 1.5 KW. (This is RF, not DC.

I have tried mine as an HT, sure beats the dickens out of hauling the FT817 (which I sold years ago). Battery life, built in tuner, mic and add-on key are great. I operate 17-20 meters when the band is good. Personally for me, I think the design, as is, was brilliant. Great grab and go for me. Do I use it for hours, nope!

I would say 10 to 50 watts on 2M/70cm and then the maximum which I think is 5 watts on 23 cm (if that too is supported). Also, features for satellite comms too would be nice. And maybe a full 1.5 KW linear amplifier for 2 meters too ? OK, just kidding, I am happy with 10 watts. 73, phil, K7PEH 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From k9ma at sdellington.us Sat Apr 1 13:03:01 2017 From: k9ma at sdellington.us (K9MA) Date: Sat, 1 Apr 2017 12:03:01 -0500 Subject: [Elecraft] Amplifier Thoughts In-Reply-To: <5453EFAA-70B3-442E-91EC-B14491E823C5@ariacorp.com> References: <5453EFAA-70B3-442E-91EC-B14491E823C5@ariacorp.com> Message-ID: On 4/1/2017 09:22, John Perlick wrote: > In the case of a solid state amp, the output is matched to 50 Ohms or so. Period. So any mismatch means that RF is reflected back into the amp....where it is converted into heat. Depending on your SWR, that could be substantial! So let's say 3:1. Then 25% of the power is reflected. Note: at 10:1 you reflect 67% of the power so that means 500 W reaches your antenna and 1000W is dissipated in the Drain-Source junctions of your expensive RF transistors! Clearly, a practical solid state amplifier capable of tolerating, say, a 3:1 SWR needs an autotuner. (Very few of us have the luxury of perfectly matched antennas across all bands.) That said, the autotuner should permit maximum flexibility, including multiple settings for the same band. There should also be an easy way to change settings, so the amplifier can be easily integrated into the station control system. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From donwilh at embarqmail.com Sat Apr 1 13:09:24 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sat, 1 Apr 2017 13:09:24 -0400 Subject: [Elecraft] reply to digest In-Reply-To: References: <009e01d2aafe$69803270$3c809750$@cox.net> Message-ID: There is a solution to the digest problem.

But a big monkey wrench was forced into the procedure, when Verizon decided to stop providing it's customers with email service (via their email servers). Fortunately, (I guess), they worked out a deal with AOL, to pass the email domain name (verizon.net) over to AOL, which has enabled those of us with verizon addresses to simply "keep" them.. making it much easier than trying to use a new email service and having to advise all your email contacts as to the new address. And, I've been pleasantly surprised with AOL's web-based client features. Essentially, their web client is able to emulate all the filtering that I had with my dedicated email app on my Mac. So, for now.. it's been rather painless. And AOL's web client even works with older OSs on my machines. I guess they coded it so that it will run on any generic browser. Granted, the cost of this is having some advertising pop up on the side of my monitor screen, but it does not interfere with the operation of reading and sending email. And, after you send an email, a screen comes up with an ad... (which is how AOL pays for everything). So, I'm OK with that. 73 de Ray K2ULR KX3 #211 -----Original Message----- From: Don Wilhelm To: elecraft Sent: Sat, Apr 1, 2017 1:10 pm Subject: Re: [Elecraft] reply to digest There is a solution to the digest problem.

The following may have been covered here before but I didn't see it in the archives. When choosing the proper power transformer tap I followed the instructions in the manual: I measured my 240V line and determined from the table in the manual that the yellow tap was the best, so that's what I used. This resulted in a no-load drain voltage of around 73 volts. Last night I did two-tone TX IMD3 tests at 500w and while the results were acceptable I wondered if they could be better. Later I got to thinking that more HV might improve those numbers, so as an experiment I selected the red tap (next one down) on the power transformer and checked the HV. This time it was 81V with no load, still within the 65-85v range specified in the manual. But the third order TX IMD numbers improved across the board by an average of 2.5 dB over my first test. On the bands above 20m the improvement was over 3 dB. Nothing to sneeze at when dealing with TX third order IMD products. By the way, my KPA500 third order TX IMD performance exceeds -40 dB (IMD3 below PEP, ARRL method) on several bands as tested with my rig. One nice thing about the low drive requirements of the KPA500 (25 to 35 watts) is that the driving rig (in my case anyway) is very clean, IMD-wise, at those low power levels. I mention this because the KPA500 manual sort of implies that there is one "right" tap, but in my case there were two that were acceptable and one that was best. Of course your mileage may vary. This is a very nice amplifier - well designed, and the PIN diode switching is fantastic. So far I haven't missed my Drake L7 at all. 73, Doug K4DSP From ne2i at yahoo.com Sat Apr 1 16:55:52 2017 From: ne2i at yahoo.com (George Cortez) Date: Sat, 1 Apr 2017 20:55:52 +0000 (UTC) Subject: [Elecraft] [OT] Morse is back!!

First set the bottom of the spectrum display so the band noise level (or receiver noise floor) is at the bottom (REF). Then set SCALE to adjust the vertical gain. I think it is best to ignore the S-x amplitude and set SCALE so the strongest signals are near the top of the display. You can easily see the relative strength of the various signals. For me the vertical scale is more useful when displaying dBm rather than S-units. 73, Don W3FPR On 4/1/2017 6:38 PM, Fred Moore wrote: > Anyone have any thoughts on getting the scale on the px3 to match the > s-meter on the kx3.. > > when the kx3 is showing a s9 signal the px3 is showing about s6.. 3 > s-units.. > > I have the pre-amp set to 20db, with a precision HP signal generator a > 50mv signal does read S9 on the KX3 like it should, the px3 reads about > 3 S units lower.. > > All cables are secure, and are the supplied cables between the kx3, and px3 > > Scale and Reference do not effect the delta between the readings.. > > surely there must be an adjustment I am missing in the PX3 > > This is a new PX3 built it yesterday morning, everything else works > properly.. ????? > > latest firmware KX3 and PX3 > > Regards..

The problem is that some will just reply to the digest, and the subject line is "digest" (or something like that), and the item in the digest that you are trying to reply to is buried in the mass of digest posts with no identification of what you are replying to. That means that your reply is not meaningful, and users are apt to just hit the delete button. I understand that those steps are more difficult on a smartphone. It is easy when using an email client like Thunderbird. As I have stated, I suggest receiving individual emails and sorting them into an Elecraft folder. That way you can reply to individual posts without the bother of deleting a lot of information. I do not receive email on a smartphone, so I don't have any suggestions for handling that. Oh yes, when replying to an individual email, snip all but the relevant information, and the stuff added by mailman.qth.com should be deleted as well. 73, Don W3FPR On 4/1/2017 9:59 PM, Terry Brown wrote: > I notice that sometimes when someone replies to a question on what appears to be the digest form of the list, the entire digest gets reposted. > > I read my digest list with my iPhone and when that happens the digest gets extremely long. > > How can I guard against this if I reply to a digest message.

I got the same advice, but mine were quite tight. If you have problems with erratic SWR or Power readings, check those screws before sending an email to support. :-) An update on the broadcast station interference problem aka the antenna problem. I looked at KLIV's data in the FCC database (thanks Jim K9YC for the links). It turns out that after sundown, KLIV changes the pattern of its antennas to put most of the power directly toward my QTH. . No wonder I have a problem. Jack, W6FB wondered how long a coax stub for 1590 KHz would be. A quick back of the envelope calculation came up with a bit more than 100 feet. I pulled out a piece of RG-58 labeled 104' and hooked it up as a stub. The problem get a lot better, but it had a noticeable effect on the bottom end of the 160M band. The stub is far from being a notch filter. Adding another piece of coax got it below the 160M band, but I worry about suppression of odd harmonics at higher frequencies. I think I have used the antenna for QSOs on every amateur band from 160M to 6M inclusive. So on to something that took longer than 10 minutes to try. I dug through the junk box and found a 560 pF 1KV cap and a T68-2 core. Quality time with the ARRL Handbook said to use 56 turns on the core, which I did with some #30 wire. So far, knock on wood, this seems to get proper power output on the entire 160M band. And the core only gets warm if you hold the key down for a long time. I'll need thicker wire before the next 160M RTTY contest. 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | Security is like Government | Periwinkle (408)356-8506 | services.

Most ham antennas don't exceed 3 to 1 SWR even on the band edges. New amps that are constructed with LDMOS finals should be able to handle nearly all antennas without a tuner. Operating a legal limit amp into an antenna with an SWR greater than 3 to 1 should be avoided for many reasons, such as: poor radiation efficiency, harmonics, RF in the shack, RFI, etc. 73, Dick- K9OM In a message dated 4/1/2017 8:48:28 P.M.

Period. So any mismatch means that RF is reflected back into the amp....where it is converted into heat. Depending on your SWR, that could be substantial! So let's say 3:1. Then 25% of the power is reflected. Note: at 10:1 you reflect 67% of the power so that means 500 W reaches your antenna and 1000W is dissipated in the Drain-Source junctions of your expensive RF transistors! Clearly, a practical solid state amplifier capable of tolerating, say, a 3:1 SWR needs an autotuner. (Very few of us have the luxury of perfectly matched antennas across all bands.) That said, the autotuner should permit maximum flexibility, including multiple settings for the same band. There should also be an easy way to change settings, so the amplifier can be easily integrated into the station control system. 73, Scott K9MA From k2vco.vic at gmail.com Sun Apr 2 00:14:49 2017 From: k2vco.vic at gmail.com (Vic Rosenthal 4X6GP) Date: Sun, 2 Apr 2017 07:14:49 +0300 Subject: [Elecraft] [OT] Morse is back!!

In my previous post, I referenced S9 and 50 microvolts, thinking most people on the list are not use to referencing dBm, that was my error. After re-reading my original post I even said mV when I intended micro.. I should have been more specific, and correct.. I do not expect the PX3 to be a precision instrument, however I am trying to resolve and understand a 10+db error here, huge to me, which should not exist according to the PX3 manual, but may be in the PX3 specification if its specification is +-10%. As a side note the PX3 scale does appear to be linear, relative to dBm, i.e. the error is the same through the usable scale.. If that is normal I can live with it, I simply want to understand if this is what others are seeing.. and make sure this new to me PX3 is operating correctly..

Message-ID: I got my second KAT500 tuner to use with my new backup rig and while setting up and testing and tuning with my two different antennas I made a mistake. I first observed the results displayed on the utility program operate page where the tuned SWR was 1:1 and the bypass SWR was something like 54:1. I immediately realized that something was not right and discovered that my coax cable was not switched to the antenna but rather my dummy load but the cable to the dummy load was disconnected (because I was moving things around). OK, fixed that little problem but I was curious about the behavior when the KAT500 tuner is faced with an impossible match. Does it give up? I assume it gives up but then I didn?t see anything to indicate that the tuning operation gave up. In fact, it seemed like it found a tuned LC solution but one that was matched with a bypass of 54:1. My first question: If KAT500 fails to find a valid solution does it report an error. I ask this because at times I have had red LED lights flashing on a failed tune but I did not have one this time. I am wondering if I missed the error report on the utility program. My second question: Is it possible that the KAT500 did resolve a tuned LC solution with basically 6 feet of coaxial cable unconnected with anything?

The operator went in and successfully tuned the antenna to a 1:1 match and then loaded the KW amp to full output. He then went S&P to get warmed up but heard very little and could not work any of the few stations he did hear. We went out and discovered that the vertical wire had snagged on the ground rod! The tuner was manual but imagine the same principal applies. Yes, you can often get a "perfect" match but that may not count for much! Have often wondered if the earth worm population in that area ever recovered.

I used a trick that was used by the telecom people, where they connected the local exchange battery across two plates and blew off all the crud. 50 volts at many hundreds of amps did the business. My way was to connect my ground plate to the incoming 240 volt supply main, via a MCB and each time the MCB tripped, I substituted bigger one until I had no more larger values. ISTR I got to 40 amps and settled for that. I had obviously made sure that no person or animal could get near the area whilst the power was on, but I was quite surprised to see how many earthworms had scuttled their way to the surface. 73, Alan.

[:-) I had a Morse SMS message composer on my Android phone several years ago. Send Morse to it with two fingers and it created a text message. It's not there any more, it was a solution lacking only a problem. If, however, you are an ARRL member, in the Oct 1949 issue of QST, you will find an article introducing the secret to perfect Morse ... keyboards, other than typewriters and teletypes, and electronic keyers were yet to be invented. It used a four-finger switch arrangement, and the author, one A. F. Scotten, W6ZMZ, even offered a sentence to prove its superiority: "Then after Richard had arrived he and Clarence each kissed beautiful annabelle and she ceased all resistance because in actual fact she liked it better than ever Ignoring the fact that is is a fairly racy sentence for QST in 1949, he asserts it has no consecutive dashes and is thus very hard to send on the keys/bugs of the day. The secret to perfect Morse? Send the spaces instead of the dits and dahs.

I can throw it up about anywhere I go at a moment's notice and make CW contacts at 5 watts with little effort. It packs small, works in pretty much any position, easily repaired, fits in a camera bag with the radio, battery and everything else needed for a day of fun. Yesterday I was at Mason Neck WWFF KFF-1308. Dragged one end up a tree almost vertical, ran between 3 and 10 watts and worked 14 stations including Belgium with minimal effort. Time from start of setup to on the air maybe 10 or 15 minutes. Whatever other antenna you may find, it still might be worth bringing an end fed along.

For a trip to ZF last month, I took several old Walmart crappie pole pieces and built a 22 foot mast by judiciously selecting and cutting pieces no longer than 28 inches so that the sections would stack and the disassembled antenna would fit diagonally in my suitcase. I'm hoping that has forever solved the air transport of fiberglass mast problem. Its not as bulky as it might seem because the narrower pieces stow easily inside the wider ones. And Walmart crappie poles aren't exactly heavy duty. I did find that unless you are good with puzzles, it is a really good idea to number the sections in order of assembly. Don't ask...... As far as high rises go, if you can get a wire 6 feet out and drop it vertically it can be an amazing low band antenna - you need a weight on the bottom that can't hurt anyone, like a hotel size plastic shampoo bottle or a small bean bag like the tree maintenance guys use, and if you land the weight on the ground somewhere out of the way, rather than letting it swing or be near a pedestrian pathway, you are much better off. In that case some monofilament for the last ten feet or so keeps the rf away from whatever is there on the ground. My kx3 rarely has any trouble tuning that set up if you throw a counterpoise wire around the balcony or can ground to a railing. Have fun.

[:-) About the "best" I've found for other than Class 4 mountaineering is a small mag loop. I use an Alexloop [a little pricey] but they are easy to build for very little expense. If you do choose to build one: 1. Voltages/Circulating currents can be surprisingly high in loops, even at QRP. 2. Use a capacitor with a 10:1 reduction on the shaft.

They know what happened apparently, which is way beyond my capability to understand or explain, and are in the process of making the changes and improvements Gerald found and these changes will be implemented in the next SmartSDR version.

You will also trigger a fault if: 1) The RF power is above 110 watts while tuning to protect the relays from arcing. 2) The impedance can be matched but is outside of the KAT500's normal tuning range with an impedance that may produce RF voltages that could damage the components considering the RF power applied. In that case, the fault occurs when you raise the RF power. However, it is safe to operate at any power level below which the fault occurs. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Sunday, April 2, 2017 2:12 PM To: Phil Hystad; Elecraft Reflector Subject: Re: [Elecraft] KAT500 tuning behavior when the load is impossible to match ?

As well as allowing you to page through the digest, it also allows you to treat the individual messages as attachments, so you can open up the specific message and reply to it. That way, you get the correct subject, and, more subtly, you get the correct In-Reply-To header, so that forums and good mail clients can properly place the reply in the thread. That's how I do all replies to this list. (Note Thunderbird does have some bugs, e.g. I had to delete a redundant "Re:" from the subject. It can also be a little fiddly working out which instance of the subject is the correct one in the attachments.) Unfortunately, the top posting policy of the list reduces the incentive to trim posts, meaning people who do end up quoting the digest don't think about pruning it. Failing to prune is also bad for readers of the digest, as they have to page over the complete back thread. This has been top-posted, but also pruned, as it would be for an interleaved posting (popularly called bottom posting, although not everything need be at the bottom).

My best results have been with an Alex Walkham Magloop (has a nice small carry on bag that also fits in my suitcase) closely followed by the Superantenna MP-1 which fits in an old Targus laptop bag. I think some hotel management groups take poorly to 'fishing' off the 17th floor balcony of their prime ocean view tower. Last time I did that was the last time I'll ever try using an End Fed Vertical Wire hung from a fishing rod (it was a surfcaster)... even after dark. If I hadn't been a top tier frequent stay guest with the company, it might have gotten ugly. Some guest below reported me for dropping a camera to look into rooms... It was just a small weighted ball on the end of the wire. The manager was polite, but asked me not to do it. I was using the FT - 817 at the time so I luckily wound up only restricted to UHF/VHF ops and suffered a temporary reddened face. Glad it was a short stay. Never had the problem with the other two antenna configurations. Jack KD4IZ Sent from my iPad > On Apr 2, 2017, at 20:08, Fred Jensen wrote: > > ICYDK, > > Crappie [n.

So when faced with that, do you break the window (not recommended) or operate from outside the building or operate with a loop placed inside the window glass. In other words - it all depends. Be prepared for all possible situations. A mag loop and an end fed antenna with some sort of support pole seem to me to be the best combination. 73, Don W3FPR On 4/2/2017 9:22 PM, Michael Aust wrote: > Tom, > Will be operating QRP with KX3 & Versa-Antenna & the 27ft poles at the Lagoon at the Disney Hotel in Wakikoloa > on the Big Island drinking Mai Tai's and working CW From drzarkof56 at yahoo.com Sun Apr 2 20:04:04 2017 From: drzarkof56 at yahoo.com (Doug Millar) Date: Mon, 3 Apr 2017 00:04:04 +0000 (UTC) Subject: [Elecraft] Portable Antenna References: <640337200.9180382.1491177844024.ref@mail.yahoo.com> Message-ID: <640337200.9180382.1491177844024@mail.yahoo.com> Well,? this works the best for me for portable. ??

Does anyone have any experience using a K3S to drive a Heath SB-220 linear amplifier? This is a 40-odd year-old amplifier with two Eimac 3-500Z tubes. My questions are: (1) What connections need to be made between the K3S and the SB-220; how much drive is likely needed; and what would be needed to run full break-in on CW? The SB-220 does not have its own break-in circuitry, but there are numerous vacuum relay-based modifications out there. (And yes, I do have a KPA500 that I expect to use most of the time. I just want to be able to switch over to the SB-220, which provides far more power output.)

They also are obtrusive when installed. The AlexLoop or magnetic loop antenna on the other hand does not even require a pole and is unobtrusive. It can be used inside a frame or brick building though is not so good in a steel structure though if close to a big window might do some good and certainly is happy on a balcony. If you have a roof garden that is nice for operating outside your room. For travel the AlexLoop is very hard to beat. Now if staying with my brother I look for my end fed dipole and run it about twelve to fifteen feet above ground and yes it will outperform the AlexLoop. Still you will make QSOs and plenty of them with the AlexLoop running 5 Watts and using CW. I can not testify as to effectiveness with SSB. If you want a short four foot long pole for the AlexLoop and this is not necessary then use a broom stick possibly whittled down at one end. You can also take some fibreglass tube cut it into three sixteen foot length and use two wooden dowels to join the three sections. The dowels are whittled down for a nice snug fit. When operating from a hotel it is best to be unobtrusive. That is for certain. It is all good fun. 73 Doug EI2CN -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of rich hurd WC3T Sent: 02 April 2017 23:42 To: Michael Aust; elecraft at mailman.qth.net Subject: Re: [Elecraft] Can Anyone recommended a great QRP Antenna and Antenna Pole for KX3 A Shakespeare WonderPole. 20' extended, collapses to 4'. $21 at Walmart.

The most common source of intermittents is cords and connectors that are either only partially connected or have had wires stressed past breaking but held together intermittently by insulation, or were never soldered, or were poorly crimped in manufacture. Banging on the K3 jiggles all the connections on the back of the K3. Then there's RCA connectors not pushed in all the way or with too-short pins for the socket and BNC connectors not twisted home. RULE OUT the connections before tearing apart your K3. Then inside there are the TMP mini coax connectors inside the K3 not seated properly. Then pin connections to reseat several times. All these before relays. Relays will usually close again by repeatedly going TX RX TX RX TX RX.... Don't ask me how much I tore apart before I figured it out or how close I came to putting the K3 in the shipping box...... 73, Guy K2AV On Mon, Apr 3, 2017 at 4:43 AM LA7NO wrote: > Hello group, > > I have several times experienced that the K3 receiver goes 100% dead.

There are already Linux versions of at least the KX3 and XG3 utilities, they work well, but are still closed source. Those (and similar) utilities could just as well be created as Java applications, then they'll run anywhere there is a working JRE (even on a Raspberry Pi or similar.) If the authors vehemently want to keep the source closed. The APRS software YAAC is such an application, and works very well on many different platforms, serial ports included. The most excellent SimSmith RF design software too, is another great example of the use of Java for cross-platform support. Java is NOT the same as JavaScript that browsers use. Though it can be invoked from a browser (and that is where a lot of the trouble comes from) you can prevent that in the Java control applet and turn off any ability for it to be even seen as present by a browser. 73 Dave G0WBX.

The most common source of intermittents is cords and connectors that are either only partially connected or have had wires stressed past breaking but held together intermittently by insulation, or were never soldered, or were poorly crimped in manufacture. Banging on the K3 jiggles all the connections on the back of the K3. Then there's RCA connectors not pushed in all the way or with too-short pins for the socket and BNC connectors not twisted home. RULE OUT the connections before tearing apart your K3. Then inside there are the TMP mini coax connectors inside the K3 not seated properly. Then pin connections to reseat several times.

So, when I tighten PL-259s, I make sure that the teeth fit in together properly and this always gives a snug fit. Note: I am not sure if these are called teeth or not. In almost 60 years of dealing with PL-259s the only time I needed pliers was to undo the PL-259 connector that I had on my truck that had sealant on it (it was very much in the weather) and stuck besides. Then again, I don?t ever remember having any loose connection problems with PL-259s either. 73, phil, K7PEH > On Apr 3, 2017, at 7:42 AM, Don Wilhelm wrote: > > Phil, > > PL-259s depend on tightness to make a good connection to the shield. > This is an often overlooked cause of problems. > After hand tightening, snug them up just a bit more with pliers if you want them to be reliable. > > 73, > Don W3FPR > > On 4/3/2017 10:19 AM, Phil Hystad wrote: >> >>> On Apr 3, 2017, at 5:25 AM, Nr4c wrote: >>> >>> Don't overlook the obvious.

On the PL259, if the teeth around the edge of the mating shell aren't aligned to move down into the teeth of the SO239, you can "tighten" the PL259 to what seems tight, but a temperature change or a jiggle will let the teeth align.

It's very easy to not have enough finger strength to twist the shell enough to go all the way down. Mini-coax TMP connectors are bad because if the center pin does not match inside the socket it won't go down and cause an infamous intermittent that many have experienced.

This is particularly vexing when the connection is up on a tower out on a boom to a balun on the driven element. Pliers plus maxi-sealing against the weather is the rule for these. The teeth can be misaligned with stiff coax where you have to twist the coax a bit to get the teeth. Then there are the female UHF connections where there are only FOUR notches on the female connection for the two teeth on the male connector. That's very easy to get wrong. 73, Guy K2AV On Mon, Apr 3, 2017 at 10:58 AM, Phil Hystad wrote: > Don, > > In my experience, PL-259s do not get tightened properly when the little teeth on the end do not engage properly.

I do not care for web interfaces as a general rule, I prefer an email client. I use my phone/tablet for email extensively when traveling so the laptop is only needed when there is sufficient bandwidth to sync it. I can also (since it's stored locally) catch up on email, offline, also handy when traveling. One can filter/sort according to TO: address, topic and similar so mass deletions are simple. I find the digest format to be more tedious but each to their own. It's not worth extensive discussion here (Ford! Dodge! Chevy! BMW! Microsloth!). BUT: regardless of which method(s) you choose, PLEASE trim your response to the least amount of cruft. It's polite, it's faster to read and for those that still have data caps (VERY common in many areas), it matters. 73, Rick wa6nhc On 4/3/2017 8:47 AM, Guy Olinger K2AV wrote: > Not everyone wants to use Thunderbird and keep their email on their > local PC.

It doesn't matter if you think web mail is the best thing since sliced bread, or if you use some free service (I distrust Google). It isn't that hard to trim the irrelevant parts. This is true if you use the digest (nice if you fix the subject too) or if there are many replies that can be trimmed. It's just courtesy. 73 -- Lynn On 4/3/2017 9:17 AM, Rick WA6NHC wrote: > BUT: regardless of which method(s) you choose, PLEASE trim your response > to the least amount of cruft.

This feature was inspired by both the original KX2 field testers and responses to our recent question about additions to the KX line. Having four programmable functions rather than one really helps. The KX2 has fewer switches than the KX3, making it a bit more dependent on the menu for often-used functions. If you?d like to give this new release a try, let me know. (Which menu entries would you assign to PF1 through PF4?) 73, Wayne N6KR * * * KX2 MCU 2.75 / DSP 1.49, 4-3-2017 * FOUR PROGRAMMABLE FUNCTIONS: The KX2 now has four programmable functions, PF1-PF4, rather than one. These can be used to quickly access often-used menu entries. To set up a programmable function, locate the desired menu entry, hold PFn, then tap any of ?1? through ?4?. Exit the menu. From then on, the menu function can be accessed using the associated PFn switch. If a menu entry has only two values (such as ON/OFF), accessing it via a programmable function will select the alternate value, then exit the menu immediately. This is especially useful with menu entries such as DUAL RX, VOX MD, ALT MD, and ATU DATA. (ATU DATA is described in the rev. 2.73 release notes.)

A PROPER chassis-mount female UHF connector either has four mounting screws to prevent it from rotating . While there are also connectors without those mounting screws with a square side to their circular body, they must be mounted on a chassis with a hole of the same shape, and the chassis must be "hard" enough that the connector cannot rotate. Any connector that rotates when pliers are used to tighten or remove a mating connector is WRONG! 73, Jim K9YC On Mon,4/3/2017 8:50 AM, George Thornton wrote: > Exerting too much force with PL259?s can put stress on the radio SO 239 connectors, I have had some of the internal mounts work loose over time.

It also only flashes/blinks on the P3 screen, not the monitor that also displays the receive signal via the P3VGA module.

My K3 has done something similar recently. When you suspect that the RX has gone dead, try holding the Tune button and force the radio to transmit a CW carrier. I suspect you'll find that you will get no output power aswell... In this case the problem is with the local oscillator and you won't see any error codes on the display either. In my case I'd run into trouble with low out of from the KREF3 reference oscillator which was fixed with a resistor change as per these instructions ( http://www.elecraft.com/manual/E740278%20KREF3%20Output%20Level%20Modification.pdf). From memory the green LED on the top of the KSYN3A I'd installed would not light when it decided it didn't like the look of the reference oscillator, hence no LO would be generated and the symptoms were similar to the ones you described. It was intermittent and could be solved by power cycling the radio a few times, I could have sworn the odd "calibrated bump" would restore operation as well but I'm not so sure. Otherwise I'd be cleaning all of the TMP connectors with something like deoxit and making sure all of the LO and Reference oscillator connections are right. I certainly hope that you find the gremlin in your radio. 73 Matthew VK5ZM On 3 April 2017 at 18:11, LA7NO wrote: > Hello group, > > I have several times experienced that the K3 receiver goes 100% dead.

Wonder why military radios are full of glyptol, or completely potted in plastic? 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to ron at elecraft.com ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to donovanf at starpower.net From ebasilier at cox.net Tue Apr 4 03:45:20 2017 From: ebasilier at cox.net (Erik Basilier) Date: Tue, 4 Apr 2017 00:45:20 -0700 Subject: [Elecraft] New KX products Message-ID: <066f01d2ad17$6945f090$3bd1d1b0$@cox.net> Would it not make sense to produce a KX3S that combines the KX3 with the PX3, doubles the output power, and provides a full complement of I/O connectors, and a new powerful Li-based battery? -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of KD6QZX Sent: Monday, April 03, 2017 9:20 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Mounting a KX3+PX3 ?

The macros are a simple sequence of DN7;DN7;DN7 repeated ten times. I figure I?m missing something. Those macros worked FB on the K3. They work FB from the K3 Utility, current version. They can be set FB into the K3S. But the execution is ignored. All help appreciated. 73/Gary W2CS From kd2jip at gmail.com Tue Apr 4 13:07:51 2017 From: kd2jip at gmail.com (Dave Corsello) Date: Tue, 4 Apr 2017 13:07:51 -0400 Subject: [Elecraft] Elecraft Digest, Vol 155, Issue 51 In-Reply-To: References: Message-ID: <17503083-326e-416d-469d-acc8d9fe4c95@gmail.com> Having the KX2 Utility on Android connected via OTG would also be great.

It is certainly much better than the popular 43 foot vertical. However it will not typically perform the way yours did on the beach where the pseudo-brewster angle radiation is filled out. John KK9A From: VE3BWP Tue Apr 4 10:58:40 EDT 201 Its not the lightest or easiest to deploy but it could very well be the best performing portable self supporting antenna out there. Once set up its fully resonant on your band of choice and easy to change bands. I stripped mine down for 40-6m at 10lbs and fit in a charter sized suite case on a recent trip to HI9 land. With the kx3 running 10w I rarely had to call CQ more then 3 times and was creating pileups. Its large footprint does attract a bit of attention on the beach and most folks thought I was setting up a deep sea fishing rod (its a real chick magnet lol). Theres definitely no performance compromise with this portable antenna if you can tolerate the extra weight and setup time. I also tried the random wire in a tree one afternoon there which worked surprisingly well too but had to work a lot harder for contacts. This was all SSB.

Doing some investigation along with the circuit digram I think I have found my problem. Across pins 1 and 8 of U12 I'm seeing the value of R111, which is about 5k5, but thats also in parallel with the winding of L34, so I'd have expected that to have measured just a few ohms or less. So seems that my issue is an open circuit L34. The only reason I noticed this was because side by side with my more recent K2 its not quite as sensitive. On the plus side it does have a much lower noise floor. So, my question is based around if anything would cause L34 to go open circuit? I cant see anything in the circuit that might have caused excessive current or something similar. All the solder work in that whole area is neat, and I didn't over-do the heat when installing it and the components all appear to be in the correct places. It had worked, as I remember finding the peak at the time I built it, but then suddenly it wouldn't re-peak after that, but at the time I didn't think much more of it. Should I just request L34, or is there something else I may need from others past experiences? thanks in advance, Cameron - AF7DK/GM7LQR From donwilh at embarqmail.com Tue Apr 4 17:00:44 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Tue, 4 Apr 2017 17:00:44 -0400 Subject: [Elecraft] Elecraft K2 IF Amp issue and loking for advice In-Reply-To: References: Message-ID: <3c74cc1e-9be0-7038-9d43-95eb948d2c78@embarqmail.com> Cameron, There is nothing in that circuit that would have zapped L34. I would just replace the inductor. If you do not have good de-soldering equipment, L34 may be difficult to remove. I suggest destroying the present inductor if you have to, and take it out one pin at a time (get the shield off first, then work on the inductor). Be careful not to damage the thru-plated holes in the RF Board, or you will be in for a circuit re-wiring task. 73, Don W3FPR On 4/4/2017 4:49 PM, Cameron Francey wrote: > > Should I just request L34, or is there something else I may need from others past experiences? > From ron at cobi.biz Tue Apr 4 17:09:32 2017 From: ron at cobi.biz (Ron D'Eau Claire) Date: Tue, 4 Apr 2017 14:09:32 -0700 Subject: [Elecraft] K3 loss of rx signal In-Reply-To: <1189074922.475326.1491280702891.JavaMail.root@starpower.net> References: <002701d2ace8$da3ebae0$8ebc30a0$@biz> <1189074922.475326.1491280702891.JavaMail.root@starpower.net> Message-ID: <002e01d2ad87$c22ffa00$468fee00$@biz> Good point Frank.

Being clear on three sides will make that a little easier. De-solder braid and a de-soldering pump have been my tools of choice for the past 30 years..

I learned long ago that you never measure antenna gain with any BNC connectors in the signal path. Each joint would introduce intermittent loss depending on how much the cable moved. They are not very stable at VHF frequencies. They sure are convenient though for more simple tasks.

A few years ago, I added stubs to a couple of antennas for harmonic suppression, carefully placing them for optimum suppression, but didn't hear nearly as much suppression as I thought I should. One of the causes was rectification and re-radiation, as you had posted (thank you VERY much for that), but the other cause was leakage in the cabling that made up my antenna switching, and in the switching itself. Harmonic suppression can be a big deal if you're trying work SO2R on 40/80 and 40/20. The next summer, I bought a spool of BuryFlex and a bag of 83-1SPs and replaced every piece of coax in that system. I also replaced the 6x2 Array Solutions switch with the newest 4O3A 8x2 switch. Once that work was complete, harmonic suppression provided by the stubs was significantly better, and what I heard was down to the "gurgly" sounding rectification you described. 73, Jim K9YC From dhdeitrick at mac.com Tue Apr 4 21:06:03 2017 From: dhdeitrick at mac.com (David Deitrick) Date: Tue, 04 Apr 2017 21:06:03 -0400 Subject: [Elecraft] KX3 to computer connection Message-ID: <804207FB-A141-4CF6-8134-E3A7260E4012@mac.com> I have a KX3, the KX3-PCKT Cable set and a computer that does not have separate mic & headphone jacks, but a single combination jack for both mic & phones.

The I/Q output from the KX3 is a stereo feed at "Line" level. (But is still useful as a mono feed at times, especially if you want the speaker to be active too, else you'll need to make a "Y" cable from the phones jack, to serve both the PC's input, and an external speaker or phones.) The 'phones' output from the KX3 is even higher level, and is also a stereo feed. The "Mic" input of a PC is very low level. So, you'll need at least a simple two resistor attenuator between rig and PC, so as not to overload the PC, and keep the RX noise level down (as seen by the PC) I use a rough value of some 20 to 30dB, depending what parts I have about. The source impedance of the KX3 is fairly low (Ohms) and the load impedance of the PC will be fairly high (kOhms) making the needed calculations easier. Similarly, the 'headphone' output from the PC will be a fairly high level, while the Mic input to the KX3 again is a very low level, so again you'll need a simple resistive attenuator between the two. And again, the PC output is a LowZ and the input to the KX3 is a High(ish)Z, again, simple calculations. Also turn OFF the Mic Bias option in the KX3 menu. Just make sure the resistor values used swamp the actual source and load impedances, this is audio frequency signals, so no need to "match" the source to the cable to the load etc. Run the PC's output at a relatively high level, but not into distortion (test with headphones, so as to swamp any spurious PC related noises.) Use the rig's mic gain control to get an ALC level of 4 bars, with the 5th flickering when transmitting, and use the RF Power control to set the TX power level. (Use "Data A" mode, so the rig turns off any TX EQ you may have set for your voice.) If you find you have to have a very low mic gain, and it's a very coarse adjustment, then you need more attenuation between the PC and Radio. Turning down the PC's output level can help, but then any spurious noises become significant elsewhere in the audio passband, hence it's best to run the PC at a high(ish) level, and attenuate it all down to suit the mic input, but in a way that gives you decent and fine control of the mic gain. Likewise, you should see a more or less flat frequency response in your digimode (or whatever) software when just RX noise is present. Similarly, if you find you have the PC's mic gain set very low, AND the Radio's output (volume) set low, you need more attenuation between radio and PC. A request please. Check your PC is not set to make bings and burp etc noises by default from the internal sound card if that is what you use. Most external (USB type) sound cards are "quieter" (noise wise) than most PC internal cards, and also allow you to keep whatever OS related noises you want on the internal system, keeping them away from the radio. It takes a little juggling of levels etc, but you can get a very good results this way. 73. Dave G0WBX.

You established that the unwanted transmit was due to VOX. That could be due to one of two issues: A) the radio mic was picking up the sound coming from the computer speakers, OR B) the Mac is configured to send normal computer sounds to the K3s codec instead of the Mac sound card If it's A, then turning off VOX is the right dilation and you're all set. If it's B, I'd suggest that you configure the Mac to send the default audio to its own sound card, and configure WSJT, etc, to use the K3s codec.

I infer that you are feeding the inverted L at the base and working it against ground. In this circumstance, the antenna tuner is a part of the system and should be grounded to the remainder of your ground system. Think of it this way. Your tuner in in series between the inverted L and your ground which represents the other half of your antenna system. I'm not sure I would use an 4:1 unum as you are. I would put an isolator between the tuner and the run to your shack. You will be feeding the antenna through the tuner which needs to see both the ground half of your antenna system and the antenna itself. The unum will attempt to isolate parts of the system that should not be isolated. However, you do need to keep RF off the transmission line going to the shack and an isolator will accomplish this. 73, Barry K3NDM ------ Original Message ------ From: "Randy Cook" To: elecraft at mailman.qth.net Sent: 4/5/2017 2:19:30 PM Subject: [Elecraft] Grounding question on remote tuner >Weather damage repair time.

If something opened the circuit to the mains ground at the house, you could find mains voltage (120 or 240 Vac) between the coax connector from the shack and the tuner at the antenna when you disconnect it for any reason. The smart move is to run a heavy copper wire alongside the coax from a ground point in the house to the ground at the antenna so that both are grounded together. I agree with Barry about the unun. I'd not use it (and don't on my Inverted L, but I am not using an MFJ tuner either). If you have a decent "RF ground" at the tuner you probably will not need any further isolation. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Fred Jensen Sent: Wednesday, April 5, 2017 12:31 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Grounding question on remote tuner Assuming I understand your configuration and that when you say "isn?t the tuner already connected to the ?system ground? via the coax shield?" you mean the 3 ft of coax from the 4:1 transformer to the tuner: The 3 ft path from the transformer ["unun"] to the tuner is handled by the coax.

I would dispense with the "unun" and connect the antenna wire and radial connection point directly to your tuner. A few feet of wire from your tuner to those points will not make a big difference since your antenna is not resonant. The only reason I can think of to connect your tuner to "station ground" is for lightning protection. While that is a consideration not to be taken lightly, be aware that *all* ground rods must be connected by heavy wire to the utility entrance ground rod. That heavy wire is #6 bare copper but #4 is preferred. That connection is for AC mains safety, not for lightning protection or anything having to do with RF. The concept for lightning protection is to spread as much of the charge as possible over as large an area of the earth as is possible. Your radial system will help do that *if* the wires are large enough to withstand the surge without evaporating the copper. 73, Don W3FPR On 4/5/2017 2:19 PM, Randy Cook wrote: > Weather damage repair time.

This, however, can be difficult and very costly in the case of an earth terminal far from the service entrance. I believe that the NEC has provisions for such cases [e.g. a barn or other outbuilding located some distance from the service entrance]. 200 ft sticks in my mind, but don't bet your paycheck on that. Unfortunately, my copy of the NEC is located in an unknown box out of many in the garage after our move. It is at least a decade old. It will likely remain there. Possibly someone who actually knows can enlighten the rest of us.

Antenna wire goes down the pole, connects to 4:1 Unun input lug, then goes via coax to tuner. Out of the tuner to a long coax run to my shack. HOW long is important here. Lightning is not a DC event, it is an RF event, and any wire, whether coax or a #4 looks to lightning like a big inductor. Rule of thumb is that if the distance from the tower to the shack approaches 100 ft (some authorities say more than 60 ft), there's no need to bond the tower base to the house. You don't have a tower, but the physics is the same. At lightning frequencies, the impedance to earth at the antenna is probably a lot less than the inductive reactance of a bonding conductor back to the shack, and the choke adds more inductance. I would drive a couple of 8 ft rods at the antenna base spaced at least a rod length apart, bond them together, and to the radials. the sole function of the rods is lightning protection. So is bonding. The radials are not a substitute for rods, but they will reduce the impedance to earth by virtue of their capacitance to earth, which will be in parallel with the rods. The choke should be at the tuner on the coax going to the shack. There should also be a lightning arrestor there. > Choke at the rig end of the coax run. It's OK to have a choke at the rig end, but it's FAR more important to have one at the antenna. > Radials mount on ground connection lug on the Unun. It's not clear to me whether your unun is step up or step down, and you didn't say what band(s) you want this antenna to cover, but I would put the radials on the antenna side of that unun. > I was a bit confused with the tuner wiring. The manual says to connect ground lug to the ?system ground?, I assume that means the radial collection point. The instructions assume the tuner is in the shack. 73, Jim K9YC From jim at audiosystemsgroup.com Thu Apr 6 01:04:36 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 5 Apr 2017 22:04:36 -0700 Subject: [Elecraft] KX3 to computer connection.

I've found adapters on amazon to split a TRRS jack into mic in and line out connectors. I seem to recall the brand was Star. They're pretty light weight, and I haven't used them (wanted them for the ready box), so I have no idea how well they will hold up. But they're cheap enough to buy two. :) Based on my testing, that good, low cost Numark listed is a very good unit for our purposes, and can significantly improve decoding as compared to internal sound cards.

It's not the narrowband green that you would get with a green LED. Especially if you add in the fact that white "LED"s are really narrow band blue LEDs with broadband yellow phosphors, so are not peaking in the green, natural variations in colour vision, or colour vision defects, could easily cause the colour to be treated as a yellowish amber, rather than a reddish green. I would have thought using green LEDs would have been a more efficient use of precious milliamps. The display is just a seven segment array and has a manufacturer's part number, although it is possible it is end of line. I don't think it is custom, or at least not at the time of the original design. The real problems with making the change are that the LED's are integrated into the diffuser and the diffuser is behind the, unsocketed, display. I doubt you could change the colour, except before the first build, without destroying the LCD panel. It is also possible that the diffuser assembly is difficult to source; there is no manufacturer's part number for that. -- David Woolley K2 06123 On 05/04/17 22:15, Don Wilhelm wrote: > Tom, > > The LCD display on the K2 has "been what it was" from the beginning > (even for Field Test units). > The backlighting is white (LEDs, not incandescent), but the color of the > actual display is green when backlighted.

As for the diffuser, If needed I have a CNC mini mill so I could cut a piece of Plexiglass and I have a nice sample pack of photography gel filters that include many colors and some various defusing films. I was trying to avoid having to build one from scratch, That being saig I may just use it as is for a while. After all the face of the K2 is half grey so it does not quite match the K3 as it is.

Since the KX2 runs 10 watts out, more or less, you're asking for external gear to run only 5 dB better. I wouldn't consider something like that for even a moment. The existing 100 watt amp is likely the minimum increment that would be almost worth the trouble. A subsequent post about using a T1 ATU on the output of a 40 watt external amp seems ill-advised, especially for such minimal practical benefit. I'd prefer to see an enhanced KX3HP (not KX2) with KXAT3HP capable (only with stout 14 vdc external power) of the 35 watts you seek. It would sell as a unified package that is the buyer's only choice, but not as multiple components. Still ... the benefit for the effort would not be there.

Please check the Elecraft T-1 FAQ, :) *Q: What?s the highest power level the T1 can handle? Can I use my 30-40 watt amplifier?* *A:* The T1 is rated at 20 W SSB/CW and 10 W FM/AM/digital modes. However, to ensure that the design is rugged, we did stress-testing at 100 watts (very briefly?don?t do this on purpose). Things got very warm during these tests, but no damage occurred. We also used the T1 for an extended period in SSB and CW modes at 40 watts to simulate the emergency use of backpacking amplifiers. Again, this did not damage the tuner. But just to be safe, we?re sticking with our 20 W rating." 73 Linas LY2H On <<<2017 bal. 6, kt at 19:34 Mike Morrow wrote: > > > > A subsequent post about using a T1 ATU on the output of a 40 watt external > amp seems ill-advised, especially for such minimal practical benefit. > > > > Mike / KK5F>> > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to irmalinas73 at gmail.com > From richard at lamont.me.uk Thu Apr 6 14:30:00 2017 From: richard at lamont.me.uk (Richard Lamont) Date: Thu, 6 Apr 2017 19:30:00 +0100 Subject: [Elecraft] K3S SSB TX monitor Message-ID: It would be useful when operating SSB to be able to hear my own voice in the headphones, but not on the speaker, where it can cause feedback.

For example, if everyone ran 5 W maximum you'd be able to work almost all the stations you hear with the KX2 "barefoot". For us QRP enthusiasts the challenge is spotting good signals from OTHER QRP stations that tells us we are likely to be heard by them. The fun is in noting that they don't need to be locals. Sometimes signals are good at QRP levels with DX too. Therein lies the value of the QRP "watering holes" around the bands. Elsewhere on the bands, I look for solid *strong* signals to call when I'm QRP, especially with a compromise antenna. As for going QRO, I agree with Mike; I don't get very excited about anything less than a 10 dB increase. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bert Garcia N8NN Sent: Thursday, April 6, 2017 12:43 PM To: 'Mike Morrow'; elecraft at mailman.qth.net Subject: Re: [Elecraft] KX2 Matching Power Amplifier The KX2 is recommended to operate at 5 watts and below for digital modes.

But much of the limit on what you can work with 5W is not QRM, but rather the noise in the other station's receiver (man-made and static) and the quality of his/her RX antennas. I can give MANY examples of stations whose TX signal far out reach their RX capability. A club station active in 160M contests is hard to work with 1.5 kW and a full size vertical with a tower as a passive reflector, whereas I've worked all the W1 and W2 states except VT with 5W on that band. Several years ago, I had a JT65 sked with an ND station. He was running about 30W. and WSJT software said he was 16 dB below my noise (the latest WSJT-X software can decode signals as weak as 28 dB below the noise floor). I called with barefoot at about 50W. No response. Over about 10 minutes, I increased my TX power in 3 dB steps (using the KPA500). He finally heard me at 400W. And it's well known that stations in the tropics and those in summer seasons tend to have a lot more static than those at higher latitudes and in winter seasons. 73, Jim K9YC On Thu,4/6/2017 1:46 PM, Ron D'Eau Claire wrote: > For > example, if everyone ran 5 W maximum you'd be able to work almost all the > stations you hear with the KX2 "barefoot".

Things are a bit easier if you use an external soundcard, but it will work fine with the internal computer soundcard. If you use the internal soundcard, be certain to turn off systems sounds so you do not transmit those beeps and bops over the air. With an external soundcard, make certain it is *not* the default soundcard. Connect the soundcard Line Out (or spkr) to the K3 LINE IN jack, and the soundcard Line In to the K3 LINE OUT jack. You may have to switch your soundcard input from MIC to LINE IN. Then you will need to connect a COM port to the K3 RS-232 input (or the PC connector on the P3 if you have the P3 in your station). No real COM ports, use a USB to Serial Port adapter - FTDI chipset is preferred. Those are the physical connections, and are applicable to any computer, Mac, Linux, or Windows. Tell the software used for Date Modes which COM port is connected to the K2, and tell it which soundcard to use. The setup stuff varies from application to application. Set the K3 to DATA A data submode and MIC SEL to LINE - set the filter width for maximum unless you have reasons to 'home in' on a particular signal on the waterfall. Adjust the K3 LINE output level to something that produces a good waterfall color. You may have to also adjust the soundcard input slider to achieve that condition. It is best not to exceed a K3 setting of 10 for LINE OUT to minimize distortion. Once you have receive going, then you can concentrate on transmit. Set the K3 to TX TEST so you do not transmit RF (but all else works). From the software application, do a transmit. Then adjust the K3 LINE IN gain (MIC GAIN) and the soundcard output level to achieve 4 bars solid on the ALC meter with the 5th bar flashing. That is the whole story. It does not matter what the computer, or what the data mode application may be, the connections and the setup are the same. I understand that the Mac has a special TRRS connector for its internal soundcard line in and line out, but that is totally resolved with an external soundcard. For data modes, the soundcard does not have to be exotic, it is only for Panadapter displays with the computer that an expensive soundcard is needed. 73, Don W3FPR On 4/6/2017 5:07 PM, Richard Thorpe wrote: > What connections do I need between my K3 and my iMac computer to run JT65.

To prevent monitor audio from the microphone from reaching the speaker, while keeping it going to the headphones, and to do this without operator intervention, seems a simple enough requirement. Having to fiddle with the monitor level after plugging or unplugging headphones is a right pain. What I'm asking for seems such a no-brainer I can't believe it isn't standard.

Sidetone on telephones was an attempt to stop folks shouting. Maybe a lack of it is why you can hear the one sided conversations of folks talking on mobiles from across the street. For me CW monitor is for sidetone and Data monitor is just a gentle background burble to indicate all seems to be working.

Of course this is something you only want to do on phone. When operating CW, and maybe digital, you always want the monitor ON, even when using speakers. I do not understand you want to listen to both headphones and speakers at the same time, unless you have someone else in the shack who wants to hear what's going on with no risk of feedback from the speakers. Set MIC MON level to 0. Instead of listening on the headphone jack, connect your headphones to the LINE OUT jack, through an external headphone amplifier or the stereo LINE IN jack on a desktop PC sound card (and plug your headphones into the PC or headphone amp.). Note that MIC jacks on PCs may use stereo plugs, but they are almost always MONO inputs that cannot handle LINE level audio well. For convenience, set CONFIG:LIN OUT to =PHONES by tapping [1]. This allows the AF Gain knobs on the K3 to control the line out level. If running K3 Beta firmware 5.58 or later, tap [2] to to set the "T=" (TX monitor) level on the LINE OUT jack (this is a new feature). This setting is independent of the MON knob on the front. Tap [2] again to return to the prior menu state. I don't have a radio in front of me, so I can't remember what happens in the right audio channel when CONFIG:LIN OUT is set to =PHONES. Normally the right channel of LINE OUT is "dead" until you turn on the SubRx by tapping SUB. If you don't have the SubRx, all you have to do is listen to the left channel audio in both ears. You'll hear the mic. monitor in LINE OUT but not the K3 speakers. If you have the SubRx, you may have to use a switch to split your ears to both LINE OUT left and right channels when SUB is enabled, and left channel only in both ears when SUB is not enabled. You could in theory use an external relay triggered by the DIGOUT1 pin on the K3 accessory port and a macro assign to a function key to automatically control the headphone switching externally *and* toggle the SUB ON or OFF simultaneously, but I don't know of anyone who has bothered to try this.

Of course this is something you > only want to do on phone. When operating CW, and maybe digital, you > always want the monitor ON, even when using speakers. Agreed 100%. When you plug headphones in, there's a delay of about a second before the speakers mute. This strongly suggests that the muting is controlled by software, not just by cutting the speaker analogue audio directly on the back contacts of the headphone jack. So presumably the rig's software 'knows' when headphones are plugged in. > I do not understand you want to listen to both headphones and speakers > at the same time, unless you have someone else in the shack who wants to > hear what's going on with no risk of feedback from the speakers. I don't wish to listen simultaneously on both headphones and speakers. That isn't the problem. I'm just trying to keep the TX mon audio (from the mic) in the headphones and out of the speakers, without having to use macros or fiddling with controls. (All my macro buttons are used up, and if I forgot to push the button I'd be either missing sidetone or getting feedback next time I transmit. And fiddling with controls wastes time in a contest or pileup.) I use 'enclosing' headphones (Sennheiser HD25, Beyer DT100) that mean I cannot hear my own voice well enough without some sidetone, and this makes speech more difficult. As there appears to be no way of doing this at the moment, I guess this is a firmware feature request. I'm not aware of any other rig that does what I'm asking for. Historically, however, rigs had a single audio power amplifier and relied on 'dumb' switching of the amplified audio using the back contact on the headphone jack to mute the speaker. I'm inferring from the one second delay mentioned above that the K3S hardware is capable of supporting a smarter approach, even if firmware doesn't, yet. 73, Richard G4DYA From w2blc at nycap.rr.com Fri Apr 7 06:10:18 2017 From: w2blc at nycap.rr.com (Bill) Date: Fri, 7 Apr 2017 06:10:18 -0400 Subject: [Elecraft] Amplifier In-Reply-To: <8953D40C-305A-4A61-871A-7E6ECE3E07BE@gmail.com> References: <8953D40C-305A-4A61-871A-7E6ECE3E07BE@gmail.com> Message-ID: That proximity would scare me - I'd feel like I was on a skewer in a microwave oven. -- Many of life's problems can be solved by simply deciding what we can do without. - John Dolan From d.cutter at ntlworld.com Fri Apr 7 07:03:26 2017 From: d.cutter at ntlworld.com (David Cutter) Date: Fri, 7 Apr 2017 12:03:26 +0100 Subject: [Elecraft] XG3 and short whip as an air standard Message-ID: The XG3 has a calibrated output into a 50ohm load and can be varied over a wide range of power and frequency. How can I use this as a standard source for field strength measurements? For instance, could I build passive networks to match a whip to the XG3 on each band of interest and calculate the radiation from the whip knowing its input from the network? Since the XG3 output is variable, the loss in the networks can be adjusted to suit. Could I use, say a *standard* 1m copper wire whip (ie <<1wavelength on HF) to easily obtain uV/m? It could all be mounted in a biscuit tin as I once saw in a magazine many years ago. Connecting a similar whip to the K3 with its calibrated dBm facility, I'm hoping this could all connect together in a modest home facility for experimentation and learning.

I've connected FLDIGI directly and I've installed LOG4OM, although it's not directly connected to the K3 yet.

I now need to make a decision on which bridging software to use for RS232 CAT control (NOT firmware updating). LP-Bridge would seem to be very suitable, or possibly OmniRig, but neither quite as convenient as Win4K3Suite. There are possibly others, but I don't want to generate a massive list here. I'm happy enough to use the Elecraft Utilities for many things, so I ask myself whether I would really need the sophistication of Win4K3Suite, given that I'm happy enough to write my own macros and press buttons on the rig itself. Please don't criticise the various products, but I would be very pleased to hear real life experiences and constructive comparisons of the suites that are available for use with the K3, peripherals and other software, to help me decide the best way to go. 73, Alan.

The worriers obsessed over the towers but completely ignored the little transmitters they and their kids would be clamping to the side of their brains. My HF beam is 12.5 metres high on a tower. With 1kW from the amp, standing directly at the base of the tower the field strength measured was well below the guidlines for RF exposure. Living at the base of a steep sloping ridge to the south it was easy to elevate myself to the plane of the antenna beaming at me from about 35 to 40 metres. When the TX at 1kW was keyed there was no indicated increase in field strength over the background reading. Also duty cycle comes into play. There are a couple of FCC bulletins, OET65 and specifically for radio amateurs OET65B which go into a lot of detail on this subject. They are dated late 1997 and I've not check to see if there are more recent revisions.

The jury is out of the exact danger levels of RF for all the various frequencies. These distances are more of an accepted limit that protects you from inquiries regarding RF exposure. Pointing to the distances being met helps get you off the hook. People will be surprised to see how small the distances these calculations are-- especially at lower frequencies. One note often overlooked. The distance is defined as the distance from feedpoint (usually center) of the antenna. Also the duty cycle can be considered in the calculation. There are stock duty cycles for SSB and CW given in the documentation. Antenna gain may have to be included. It used to be that anything at 100 watts and below at HF was exempted. I believe that has changed. 73 de Brian/K3KO On 4/7/2017 16:06 PM, Edward R Cole wrote: > In the USAmerica ham's now have the *responsibility* of determining the > safe operating zones for each antenna per FCC regulation.

Had to wiggle the cable every few days to get rid of the extra noise on the P3. Finally replaced the cable with a 3 foot Amphenol BNC cable, part number 115101-30-36.00 and have never had the issue again. The cable is made with LMR-100, which is skinny and flexible. It's currently in stock at Mouser for $18.66. 73, Bill - NA5DX On 4/7/2017 11:09 AM, Jim LeFevre wrote: > I'm replying late to this subject as I've been out of town and have many digests to go thru...speaking of Amphenol BNC's: I have had continuing problems with the original cable to go from K3 to P3 from day one.

That said, the original KIO3 board fails to follow the good engineering practice of connecting cable shields to the shielding enclosure at the point of entry. This failure is, sadly, widespread in ham radio, computers, and consumer gear of all sorts. It is a MAJOR cause of hum, buzz, and RFI. It was brought to the attention of the world of pro audio by Neil Muncy, W3WJE (SK) in a landmark AES paper in 1994. Problems caused by this design failure are greatly reduced by the proper bonding outlined above, and by the use of ferrite common mode chokes on wiring connected to the defective equipment. Proper bonding is described in the slides for a talk I've given to several ham conventions. The concepts have been incorporated into a new ARRL book on power and grounding by N0AX. http://k9yc.com/GroundingAndAudio.pdf 73, Jim K9YC On Fri,4/7/2017 12:42 AM, Vic Rosenthal wrote: > Hmm, I am running 1.2+ kW to a dipole on the roof about 20 feet above my K3, which has no RF problems though other devices in my shack do! > > Vic 4X6GP > >> On 6 Apr 2017, at 19:28, Dennis Watkins wrote: >> >> I would suggest that a redesign on the K2/K3s would be a starting point.

Tap [2] and set the the LINE OUT MON level (T=) at the LIN OUT jack to a comfortable level. Then leave your headphones plugged in there. Now there is no way that TX MON audio will get to the mic. via the speakers, but you will hear plenty of monitor in the headphones (always). To mute the speakers, plug something into the headphone jack (doesn't have to be headphones). To unmute, unplug. Leave your headphones connected all the time, to the LINE OUT jack. If you want to operate CW with speakers (really?) you'l have to turn up the monitor. You won't have to fiddle with anything else unless you're trying to use the SubRx. > As there appears to be no way of doing this at the moment, I guess this is > a firmware feature request. > It's not clear if the hardware is capable of routing the voice monitor to the headphones without also routing it to the speaker. You can set the LINE OUT monitor level separately from the speaker / headphone monitor level, which comes pretty close to what you need. I guess what you're asking for boils down to a request for three independent monitor level settings: 1. Speakers 2. Headphones 3. Line out And you also probably want different monitor level's to be remembered for each mode. 73, Bob, N6TV From gj4cbq at gmail.com Fri Apr 7 15:19:11 2017 From: gj4cbq at gmail.com (Phil, GJ4CBQ) Date: Fri, 7 Apr 2017 20:19:11 +0100 Subject: [Elecraft] K3S SSB TX monitor - feature request In-Reply-To: References: Message-ID: <3edbb6fc-f66e-29de-8277-758025278a94@gmail.com> Jim, It might be worth your while re-reading Richard's posts. What he is asking for is the **automatic** toggling of the monitor function on insertion and removal of the headphone plug, without the use of a macro. The CONFIG:SPRK+PH setting does not achieve this. And yes, I've been using the PF2 key in the manner you describe for some years now. Bob's suggestion of using the line out sounds promising, but I think Richard is looking for a solution that doesn't involve an external headphone amplifier. 73, Phil, GJ4CBQ.

Since the adoption of OET 65 in the late 90s, all licensees (including Hams) have had the responsibility to insure their station is in complete compliance with RF exposure limit guidelines. Most likely during your last license renewal or application for a new license, you checked a box stating you would insure compliance with non-ionization radiation limits. Those guidelines are contained in bulletin OET 65. For Hams OET 65 Supplement B (https://transition.fcc.gov/bureaus/oet/info/documents/bulletins/oet65/oet65b.pdf) gives us some shortcuts to insure compliance without the tedious calculations. Many of the tables were provided by ARRL & the W5YI Group. There are also calculators available on the internet to make it quite easy. Googleing "amateur radio oet 65 calculator" returned many to choose from. The only caveat I will give is that most of the shortcuts and calculators are for a single transmitting antenna at a specific location. Multiple radiating antenna WILL change the protection distances - Field Day & group contesting come to mind! Use to be we had to submit OET 65 compliance statements when licensing all transmitters for Broadcast Stations ranging from 150 MHz to 23 GHz. I believe we finally could use just a blanket cover statement ; but it has been a while since I licensed a non-Ham transmitter. You do need to insure you are in compliance - to protect your family, friends, neighbors and yourself. 73 George AI4VZ From: brian "Considered dangerous" isn't quite right. The jury is out of the exact danger levels of RF for all the various frequencies. These distances are more of an accepted limit that protects you from inquiries regarding RF exposure. Pointing to the distances being met helps get you off the hook. People will be surprised to see how small the distances these calculations are-- especially at lower frequencies. One note often overlooked. The distance is defined as the distance from feedpoint (usually center) of the antenna. Also the duty cycle can be considered in the calculation. There are stock duty cycles for SSB and CW given in the documentation. Antenna gain may have to be included. It used to be that anything at 100 watts and below at HF was exempted. I believe that has changed. 73 de Brian/K3KO On 4/7/2017 16:06 PM, Edward R Cole wrote: > In the USAmerica ham's now have the *responsibility* of determining the > safe operating zones for each antenna per FCC regulation.

The best I ever hope for is guidance, not limits. As George notes, some people have suffered significant harm from RF fields. Others, not at all. Remember, the microwave oven was "invented" by an engineer working around magnetron RF sources and discovered the "Hershey" chocolate bar in his shirt pocket had melted. When he figured out why, the "Radar Range" (first brand of microwave oven) was born. One cold night in the late 1950's, working outside on a flight line of F-86D fighters lined up wingtip to wingtip for preflight repairs and testing, I concluded I must be catching the flu. I felt weak hot and sweaty after several minutes talking with someone. We were standing in front of the planes, most of which had the nose radomes removed for testing the fire-control radar systems. Looking up, I noticed the radar antenna of one plane across the way with someone sitting in the cockpit was pointing directly at me. On a hunch, I took a few steps to one side and the antenna twitched to follow me. I immediately moved completely out of the way and within a short time I felt quite normal. Relating the experience to other people working the flight line, I learned it was a common occurance. The concept of being "cooked" by RF radiation was new and no one thought much of it. I don't think I, nor did I hear of anyone else, being injured by the experience, although I was thereafter careful not to stand in front of a transmitting radar antenna again. Not that Lockheed wasn't paying attention. We used to gather around the tailpipes on break after an engine run, occasionally roasting a hot dog or sausage on a stick held up just inside the afterburner which often still glowed red, and they quickly forbade that practice for safety reasons. But non-ionizing electromagnetic radiation was not on anyone's "radar" so to speak back then. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Gmail - George Sent: Friday, April 7, 2017 12:55 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Was Amplifier - Now RF exposure limits Ed & Brian, My father had severe health consequences from working in a classroom with operating military radars! Since the adoption of OET 65 in the late 90s, all licensees (including Hams) have had the responsibility to insure their station is in complete compliance with RF exposure limit guidelines. Most likely during your last license renewal or application for a new license, you checked a box stating you would insure compliance with non-ionization radiation limits. Those guidelines are contained in bulletin OET 65. For Hams OET 65 Supplement B (https://transition.fcc.gov/bureaus/oet/info/documents/bulletins/oet65/oet65 b.pdf) gives us some shortcuts to insure compliance without the tedious calculations. Many of the tables were provided by ARRL & the W5YI Group. There are also calculators available on the internet to make it quite easy. Googleing "amateur radio oet 65 calculator" returned many to choose from. The only caveat I will give is that most of the shortcuts and calculators are for a single transmitting antenna at a specific location. Multiple radiating antenna WILL change the protection distances - Field Day & group contesting come to mind! Use to be we had to submit OET 65 compliance statements when licensing all transmitters for Broadcast Stations ranging from 150 MHz to 23 GHz. I believe we finally could use just a blanket cover statement ; but it has been a while since I licensed a non-Ham transmitter. You do need to insure you are in compliance - to protect your family, friends, neighbors and yourself. 73 George AI4VZ From: brian "Considered dangerous" isn't quite right. The jury is out of the exact danger levels of RF for all the various frequencies. These distances are more of an accepted limit that protects you from inquiries regarding RF exposure. Pointing to the distances being met helps get you off the hook. People will be surprised to see how small the distances these calculations are-- especially at lower frequencies. One note often overlooked. The distance is defined as the distance from feedpoint (usually center) of the antenna. Also the duty cycle can be considered in the calculation. There are stock duty cycles for SSB and CW given in the documentation. Antenna gain may have to be included. It used to be that anything at 100 watts and below at HF was exempted. I believe that has changed. 73 de Brian/K3KO On 4/7/2017 16:06 PM, Edward R Cole wrote: > In the USAmerica ham's now have the *responsibility* of determining > the safe operating zones for each antenna per FCC regulation.

Had you done that you would see factors for modulation, duty-cycle, antenna gain, etc. Next,I could not recall the FCC paper: OET 65B, but VK3UM based his spreadsheet on this paper a similar papers done by European authorities; note the "safe"levels differ between which gov't authority is used. The FCC did thorough study and came up with the guideline since they realized not all parties had the equipment or expertise to measure near-field RF power density. Thus the simplifying guide which will generally suffice. More likely one can enter a few known parameters about their station vs a total field density measurements. I was responsible for 62 FCC commercial licenses and seven transmitting sites, so I did the FCC calcs by hand with calculator way before Doug wrote his EMR program. Also did mw safety measurements in the 1970's at NASA Goldstone Facility. The 25mw/cm^2 measured at two miles would not pass today's limits. 85-foot dish pointed at you running 20KW CW at 2115 MHz. I too have experience effects of mw radar testing with open waveguide (3kW peak). Took about ten minutes to start getting a headache. Then I threatened the stupid tech doing that with certain bodily injury if he did not use the dummy loads - duh! I merely wanted all you on the list to know of this handy resource for calculating your RF exposure per gov't standards. Its a minimum to try for. 73, Ed - KL7UW Date: Fri, 07 Apr 2017 16:27:18 +0000 From: brian To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Was Amplifier Message-ID: <58E7BDE6.1000107 at comcast.net> Content-Type: text/plain; charset=windows-1252; format=flowed "Considered dangerous" isn't quite right.

Being an RF guy I was asked once to design and build a 225 MHz PA that would deliver a couple of hundred watts output when driven by an HP608 signal generator. The object was to drive a 10 dB gain Yagi that would illuminate a Phoenix in a lab to simulate what the missile was seeing under the wing of an F-14 on the deck of the carrier Enterprise. Phoenix had a feature called MOAT (missile-on-aircraft-test) that preformed some limited tests just before the aircraft was launched. A lot of failures were happening that could not be repeated after the aircraft was removed from the flight deck and the missile unloaded. Of course this was an operational PITA that needed fixing. It was finally hypothesized that the failures were due to RFI from the AN/SPS-32 OTH radar that was a feature on Enterprise. Some analytical type determined that 100W into the Yagi 10 feet from the missile would be the equivalent of what the missile and the deckhands were seeing on the carrier deck. Since our lab didn't (yet) have an anechoic chamber large enough to do the test these guys planned to do it in a regular lab environment. I told them that I would (and did) build the PA, but I didn't want to be anywhere near it during the testing. I'm glad I wasn't on the carrier deck either.

The heating effect - which is the only scientifically verifiable effect from RF exposure - is far smaller at HF than radar frequencies. Yes, you don't look into a horn antenna of an operating radar transmitter, but a 20 meter dipole is a different story entirely. The exposure limits mandated by the FCC (and by the authorities in this country too) serve only to cover various butts against opportunistic lawsuits.

But the FCC worksheet can be completed with simple arithmetic. Every US amateur needs to fill out the worksheet. https://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet65/oet65b.pdf If you are using a mag loop, you need to do a different calculation for near field exposure.

If I need to fish a weak one out of the crud, I'll grab the headphones and plug them into the front panel jack. At the end of that QSO, I'll unplug and go back to speakers. When I transmit, I need to hear my own voice as sidetone in the headphones, but not the speakers. I want the rig to do this *automatically* without button presses, knob twiddles, the use of different sockets or any external hardware. These are all obvious but unsatisfactory workarounds. The firmware, however, does not appear to support what seems a simple and common-sense requirement. 73, Richard G4DYA From gj4cbq at gmail.com Sat Apr 8 05:55:18 2017 From: gj4cbq at gmail.com (Phil, GJ4CBQ) Date: Sat, 8 Apr 2017 10:55:18 +0100 Subject: [Elecraft] K3S SSB TX monitor - feature request In-Reply-To: References: <3edbb6fc-f66e-29de-8277-758025278a94@gmail.com> Message-ID: <3845fbad-5621-0fd6-9fb0-5c8f4ef8b928@gmail.com> Thank you Richard. Having slept on it, I realised that my earlier retraction, as a result of Joe's posting, was somewhat hasty. I blame tiredness. It all hinges on Joe's statement: "Richard admits that he does not need the speakers when he is using headphones/operating SSB" Re-reading the posts this morning confirmed that you hadn't actually said that. My posting yesterday evening was based on the understanding that you wanted to operate SSB using either speaker or phones. Thanks for confirming this. Prior to my original posting I tested CONFIG:SPRK+PH on my own K3 and confirmed that it didn't toggle the monitor function. 73, Phil, GJ4CBQ.

The RPi-3 is a wonderful host for wsjtx and fldigi. It controls the kx2 like a dream with only two short audio cables to a $5 usb sound card and the included usb cable. I can then control my kx2 via the RPi-3 using a virtual network computing window on a remote desktop. This allows me to control the kx2 in the drafty, cold shack from the comfort of my computer room upstairs (or anywhere else, for that matter). The only drawback is getting kx2util installed so I don't have to drag it upstairs for an upgrade. I would appreciate detailed instructions if anyone has had success!

Your 'need' to hear your own voice during transmit is not a common (to my experience) requirement. There is often a slight phase shift and it's distracting to most so they simply mute the receiver and are satisfied with the silence. If it is (as you've stated twice now) a 'common sense requirement' I daresay that Elecraft would have already implemented it; they're rather good at doing that. Perhaps it's simple to allow, that's an unknown. However stridently insisting that any particular way is common sense that is contrary to the majority belief is not the way to endear oneself to those that are capable of creating a means to have it your way. There IS a work around and you're aware of it. The vinegar:honey rule applies. Perfection is an illusion because it's perspective based.

Whether or not there's a 'need' to hear your own voice in the headphones during transmit depends partly on the headphones. The better the isolation of ambient sound they provide, the greater the attenuation of the natural mouth-to-ear path. The two models of headphones I have both provide excellent isolation of ambient sound. That's partly why I bought them. (Originally for audio production work, not amateur radio.) (Sennheiser HD25 and Beyerdynamic DT100.) I find that so much isolation makes it difficult to speak. It feels as though I've suddenly gone deaf. The need to provide one's own voice in headphones, and keep it out of any speakers in the same room, was recognised by radio broadcasters decades ago. Pretty well every broadcast studio that's ever been built caters for it. I disagree that a 'slight phase shift' is distracting. A delay (of tens of milliseconds or more) is distracting. Elecraft caters for this with CONFIG:TXMON NOR or FAST. I use the latter and it sounds great. > If it is (as you've stated twice now) a 'common sense requirement' I > daresay that Elecraft would have already implemented it; they're > rather good at doing that.

I'm not sure quite what your evidence is for any 'majority belief'. And if the need to keep microphone audio out of the speaker is not common sense ... then what is? Does not every engineer learn this at his mother's knee? My pointing this out is not a criticism of Elecraft. (If anything, Elecraft is ahead of the game by providing voice sidetone at all.) > There IS a work around and you're aware of it. The vinegar:honey > rule applies.

In-Reply-To: References: Message-ID: <61ed5eda-56db-56f9-ed2e-0fd52d0030a2@sonic.net> I don't believe this is a limitation of the K2. The panadapter bandwidth is limited by the bandwidth of the sound card. By the way, if the sound card's sample rate is 192 kHz, the panadapter bandwidth is actually somewhat less than that, limited by the anti-aliasing filter in the sound card, typically 170-180 kHz. In contrast, the P3 bandwidth is flat out to 200 kHz.

Not hearing this does make one feel deaf. This is a common feature in professional intercom systems as well as music performance monitoring for singers and instrumentalists and even your telephone! It's not really a "nice to have": In my opinion, it's a "must have". Yes, the rig doesn't do this automatically. Yes you have to twiddle some knobs to get it done. However, there is a very simple solution that allows this feature requirement with ONE BUTTON PUSH. Yes it requires an external device, but it also adds additional flexibility and features for an insignificant price vs the cost of the radio. This device is the Behringer MIX800 modular 4 channel dual stereo input headphone mixer. I have had this device in my K3 audio path for 9 years now. I feed the line out of the K3 into this device. Since I have a KRX3, I feed the main RX into input #1's right channel and the second receiver into the left channel. I set the radio to give me main in both ears and second receiver in left ear only. Since the device has two inputs, the second input is left unused and becomes "input mute". I don't use the radio's front panel headset jack for headphones at all. This device has four independent headphone level outputs with 1/4inch stereo jacks on both the front panel and the back panel. Each channel has an independent level control and a/b input switching. I feed channel 1 out to my station speakers (Yamaha self powered computer speakers) via the rear panel jack. I feed Channel 2 to my headset via this channel's front jack. I feed channel 3 to my audio recorder using the rear jack. Channel 4 is unused, but permanently wired and ready to use as an output for anything with just a 1/4inch stereo plug. A push button on each channel controls routing/muting to each individual line level output feed. When I need to mute my speakers, I press the channel 1 button. The green light goes out, and my speakers mute. When I don't need to record the output, I press the channel 3 button, the green light goes out and the channel is muted. If I don't want to feed my headset, I press the channel 2 button and my headset mutes (but both the speakers and the recorder feeds stay on if I have them selected to be on. All four outputs can be controlled individually in any combination of on or off state at the same time, speakers, headset, recorder and auxiliary audio because each is individually switched. The BEST thing about this is that each channel has its own level pot. This means that I can have the recorder level set and vary both the speaker level and the headset level INDEPENDENTLY. I don't run monitor very loud at all at any time, so I don't get feedback with monitor on the speaker line when I use speakers. When I record I get BOTH my transmit audio AND the receiver audio, and in SPLIT I get BOTH the TX frequency AND the receive frequency on all recordings. An added feature is that the headset mixer has its own BALANCE control, so I can vary the ratio of the second receiver in my left ear only vs the level of the main receiver in BOTH ears. with one pot, yet STILL have independent output level when I want it with the radio's concentric AF level pot. So I can have both features on at the same time: Not possible with just the radio, it offers either one OR the other (Balance OR Independent receiver out on the concentric pots). If you have a second op, you can use the fourth channel for their headset and they then have their own individual level control separate from yours, your speakers and your recorder AND THEY WILL HEAR YOUR VOICE as well as the receiver output. This is nice for things like Field Day or Contesting with a "partner". It's really the best $40USD I have ever spent on my station. BTW, absolutely no RF feedback into this unit on any band using my KPA500 at full power. No notice of its wall wart power supply in my receiver either. I believe this device will solve this need for the rig as is. While it would be nice to have this all built in to the radio, its currently not, and I believe it wouldn't be that high on the priority list for development. But this solution is both cost effective and offers additional functionality for a very little capital outlay. It works for me here. It may work for you if you require this functionality. 73 Lu Romero - W4LT Tampa, FL K-Line system since 2010 ----------------------------------------XXX--------------------------------- -------------- Rick, Just to point out that I didn't write that.

Changing the operation of the K3/K3S to enable monitor *only* when the headphones are in use would cripple current operation *and* make it impossible to monitor data and/or CW modes via the speaker. As pointed out by many in this discussion, using CONFIG:SPKR+PH by assigning it to a PF/Macro key to turn off the speaker when one is using the headphones is a useful alternative. That solution has been used by many operators who leave their headphones connected at all times *for many years*. When you start proclaiming a "simple and common sense requirement" take a little time to determine if the hardware will even support such nonsense! Note: *none* of the YaeComWood transceivers support such a "simple and common sense requirement" - they all feed their headphones from the speaker amplifier through a mechanical switch and current limiting resistors!

I studied the K3 schematics a few days ago. I've just studied them again. Thanks for the reminder. On receive, the rig is capable of muting the speakers when the headphones are plugged in. This is quite normal. This happens despite the two audio amplifiers having parallel inputs. There are switch contacts on the front panel headphone jack that enable the rig to 'know', firmware permitting, whether there's a jack plug in the socket. There is also a line labelled MUTE1 connected to the pin 2 of the speaker amplifier U1. So the hardware exists to enable the firmware (a) to know whether headphones are plugged in, and (b) to mute the speaker amplifier. This hardware is, AFAICS, used on receive. All I'm asking for as an option to do the same thing on transmit, if a particular set of circumstances is true: Is the rig on a voice mode? Is the audio input set to mic (not line in)? Is the rig transmitting? Is there nothing plugged into the front panel headphone socket? If these four conditions are all true, then mute the speaker amplifier. 73, Richard G4DYA From richard at lamont.me.uk Sat Apr 8 14:12:58 2017 From: richard at lamont.me.uk (Richard Lamont) Date: Sat, 8 Apr 2017 19:12:58 +0100 Subject: [Elecraft] Feature Request In-Reply-To: References: Message-ID: <2c61f590-fd9c-0b4d-c884-51e7006db64d@lamont.me.uk> On 08/04/17 18:58, Mike Harris wrote: > I'm losing track here.

Here's the deal: 1) the original poster is using the front panel PHONES jack, and has SPKR+Phones set to NO. This makes the radio behave like most rigs we're used to - i.e., plugging in the phones mutes the speaker. In this case, if Monitor is on, it comes through phones OR speaker, whichever you're using at the time. There is no provision to enable/disable Monitor based on whether the front panel phones are plugged in, which is what he wants. 2) If you use the REAR panel phones jack, the monitor audio comes through the phones as expected. If SPKR+PHONES is set to yes, the RX audio comes through the speakers, but the transmit Monitor audio does not. At least, that's the behavior with my K3, MCU version 5.57. I just tested the two scenarios above. For the record, my normal configuration is to use the rear panel phones and mic jacks, with SPKR+PHONES on. I do have PF1 set to toggle that off, but rarely do, since I'm usually alone in the shack. I have yet to hear any kind of audio feedback when transmitting. I have no idea if the behavior is any different using the front MIC jack, as I never do. I'd be interested to hear if anyone has a different experience. Incidentally, while testing option 1 above, I unplugged the phones from the front and cranked the MONITOR until it was unpleasantly loud from the speakers, but got no feedback howl, but that may just be a function of placement.

I have seen several controllers for the ICOM AH-4 tuner. My questions are about operation with a K3s. 1. Is there a limit to the time that 10w of RF can be sent to the AH-4 via the K3s Tune button? 2. All circuits specify a momentary switch, but does momentary mean 0.1sec, 1.0sec or 5seconds? Does the time matter? 3. When the complete signal returns from the AH-4 should the Tune RF or the momentary be terminated immediately? 4. Is there a combination of momentary or Tune RF that will damage the AH-4? I have an AH-4 which worked with a home built controller for some months, and then became operationally intermittent and final fails to work at all. That makes me gun-shy, about buying another even though the AH-4 gets excellent reviews on eHam, almost all of which are based on an ICOM rig control.

Thanks - Murphy, KB3EOF Sadly, it will never work natively on a RPi as things are now. The program is compiled for use on an X86 CPU, so even if the RPi had WINE (and I doubt if that would run anyway) any Windows program would fail due to the CPU architecture differences. The Linux (and OSx) versions of the KX* utilities likewise are also compiled only for X86 processors. Lot's has been discussed on this list about this in the past, but Elecraft and the software authors do not want to make the jump to the Pi, or make the code open source so we could build it ourselves. Frankly, that's a crying shame, as it would be relatively trivial to build the Linux version on the Pi, unless they are using some "secret" third party libraries internally. Running Qemu (or VBox etc) isn't going to help either, it they don't emulate the X86 CPU as far as I know. The exagear X86 emulator looks interesting, but I've not seen that before or tried it. Looking at their website, the cheapest version is only some ?11 (UKP) but emulates a Debian8 system, so you'll still be in Linux, but the Linux versions of the util's should then work I suspect... I run the KX3 and XG3 utilities on Mint (on a X86 laptop) and that's based on Ubuntu, that is in turn based on Debian. They work very well. 73. Dave G0WBX.

My experience with running Windows on a PowerPC Macintosh was that if the program wasn't too CPU intensive, the experience was only a little lethargic. Running photoshop was like watching paint dry. It's certainly worth a try. Assuming gemu is not satisfactory, and given that Elecraft does not want to open source the utilities, I can see some options: * Leave things as they are. People who use Pi based portable systems have to hope they don't need the utilities while away from their Intel based computer. Or carry extra stuff. * Add a Linux ARM utility to the mix using their current resources. This option would probably be fairly easy, since most Linux just programs compile for both CPU architectures. There would still be extra testing needed. * Look for a volunteer who will maintain the Linux ARM utilities under NDA. 73 Bill AE6JV On 4/8/17 at 5:00 AM, elecraft at mailman.qth.net (AE0MM via Elecraft) wrote: >The Raspberry Pi line of computers use ARM-based CPUs.

That is still a failure mode for all those who leave a headset (or headphones) connected all the time but only put them on when using a headset mic. There is no way for the rig to to know if the device connected to the front or rear headphone jack are 1) headphones only only or 2) a headset (with mic) and 3) if the headset mic is actually in use. Yes, it it possible to turn off the speaker amplifier but there is still no sensor that will tell if the headphones are actually in use just like the YaeComWood mechanical switch can only tell if a plug is inserted in the jack. The speaker amplifier is currently disabled whenever headphones are connected to either jack with CONFIG:SPkR+PH=No. Disabling the speaker amplifier whenever headphones are connected to either jack is *unacceptable* to hundreds of other users who routinely leave headsets connected - particularly those who use headsets connected to the rear panel jacks (and before you say "mute on connecting to the front headset jack" - the headset switches are also connected in parallel). You are looking for a solution that is unique to your own situation and would inconvenience hundreds of other users simply because you are too lazy to program a PF/Macro to toggle CONFIG:SPKR+PH when you use a headset. 73, ...

I stand corrected, and sorry for muddying the waters. No, I wasn't confusing Phones and Line Out. At any rate, at a 'normal' (for me) monitor level, it's not objectionable (or even really noticable) in my external speaker. The only way I could induce audio feedback was to hold the mic right in front of the external speaker with MON set at or near maximum. I can't honestly think of any reason one would want TX monitor audio in a loudspeaker, but I guess that's the way it works, so somebody must think it's a good idea. I can't say I've ever noticed it until doing this test. Whether it results in audio feedback depends on your monitor level, your mic, your speakers, and the placement of mic and speakers relative to each other.

The AM and FM stations where I worked only had a speaker in the booth over which the DJ heard audio from the disk on the turntable or rare network feed. He/she never heard their own voice. Same was true in aircraft and military radio comms. And I doubt if many Hams today carrying an HT are disturbed by not hearing their own voices. Sidetone in telephones was used to keep the person speaking from shouting (as they did in early phones). The higher the sidetone volume, the quieter the person would speak. We used that to great effect to tame a "shouter" in bull-pen office environments. Unfortunately mobile (cellular) phones offer no such benefit. My point is that I suspect that you are tapping into a change in recording, broadcast and DJ work that is beginning to impact Ham operations. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Luis V.

Remember last New Year's Show on ABC-TV? The non singing Mariah Carey? She had clean mix minus in the floor monitors, but no earpiece sidetone feed :) But there are exceptions. You may be one of them. Ever watch a TV liveshot where the person on camera yanks out their earphone? They are probably being fed DELAYED audio over the IFB. That's a really bad thing! Some delay is acceptable, and some on camera talent are very good with filtering out the delay. Most cannot. This has become a nightmare now in Digital transmission with the added latency introduced by modulation codecs. Gone forever are the days of feeding main channel with IFB over ProChannel or 450MHz BAS transmitters (although there are still some stations out there that do this... Its "traditional"). And I will agree with you on HT carrying hams. Especially Digital Modulation ones. There is copious processing delay with Digital Modulation. That would drive most people mad! I can sense the K3 delay when listening to my processing in my rig's monitor. I find it within my window of manageability and I like to hear sidetone in my headset as I have been accustomed to by 41 years of using headsets over RTS/Clearcom/Riedell intercom in broadcast control rooms, never on speaker. I could live without it... But I prefer to have it. However, I can also see 2 frames of video to audio delay... It's a curse, not a blessing in the digital world we live in today.

That makes me gun-shy, about buying another even though the AH-4 gets excellent reviews on eHam, almost all of which are based on an ICOM rig control. I have used an AH-4 for many years, with a 706MKIIG and with various other manufacturer's radios, including now a K2. Other than the limitation to ~125 watts, these are excellent. I only run 5 watts so it is not an issue. I do not recall a situation where the AH-4 would not give a useable match, provided I provided it a plausible antenna. I use a separate SWR/watt meter that shows it working. The momentary switch is push on, release off, no time specified. Pushing the button signals the AH-4 to run through its paces for a match. Most often, it is very quick. Occasionally, when you have gone from, say, 15M to 80M, it might take a little longer, but never more than several seconds. If no match can be found, it just stops. Either way, you stop the power. I wouldn't let it just run like that, but have never heard of damage because of it. You need to reduce power with non-Icom rigs that don't do it automatically. You might join the Icom tuner Yahoo group, if you can stand Yahoo. Lots of user experience there. I've never seen a store bought controller for the AH-4. Where have you seen them? 73 Jim Allen W6OGC Sent from my iPad From lists at subich.com Sat Apr 8 22:36:39 2017 From: lists at subich.com (Joe Subich, W4TV) Date: Sat, 8 Apr 2017 22:36:39 -0400 Subject: [Elecraft] K3S SSB TX monitor - feature request In-Reply-To: References: <3edbb6fc-f66e-29de-8277-758025278a94@gmail.com> <9d9153e7-9d4f-3f1c-3c85-04577b6d4a94@gmail.com> <4f943a1f-7038-c03d-dc24-dfcba6c2bbbc@subich.com> Message-ID: <79756624-997c-53c3-e4dc-4da4d2f2f2a9@subich.com> On 4/8/2017 5:07 PM, Dave Fugleberg wrote: > At any rate, at a 'normal' (for me) monitor level, it's not > objectionable (or even really noticable) in my external speaker.

There we agree ... where the monitor level is set to be usable in the headphones, it does not cause a feedback issue even if the speakers are turned on. However, if one is using low sensitivity headphones with the speakers turned up high *and* high mic gain, one can cause feedback or echo.

It has since quieted. Last Sunday the sfu was over 100. Currently it is hovering around 70 again where it seems to have been stuck all winter. The strong auroral oval tells me there are ions coming in so the lower bands should be noisy but OK. The ELVE in Eastern Europe was interesting. I doubt the lightning ever gets that intense in the PNW. The daffodils are budding and will open in a week. That means the last snow is due. Before noon we got half an inch of pellets but we normally get a few inches once the daffodils start blooming. I think their clocks are set for warmer areas.

For the price, the KXPD3 fits perfect on the front of the KX3 and is very convenient to use. Its definitely not your $300 ~ $500 key performance. the KXPD3 is definitely not the smoothest key I have used, but more than adequate for field operation, or just relaxing working a QSO or two. I also like use b mode for this paddle. The cool thing is that Elecraft kept the external paddle port live so you can have to keys connected at the same.

Message-ID: <1491740895863-7629176.post@n2.nabble.com> Hi, does anybody have any advice for writing a macro that will allow VFOb to be controlled with the main VFOa tuning dial when operating in split mode. It gets a bit annoying having to continually tune with the small OFS/B knob, and whilst swapping frequencies from A to B works, that too can be a nuisance in certain situations. I have the programmers reference guide and have been looking through it, but I do not recognise then commands that allow you to reassign control of specific parameters (in this case the VFOb TX frequency) to different buttons or encoders (in this case the main VFOa rotary encoder). Any help or advice would be greatly appreciated. 73 de OE6FEG / M0FEU Matt -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-macro-for-swapping-VFOb-control-when-working-split-tp7629176.html Sent from the Elecraft mailing list archive at Nabble.com.

My K3 has the new synths (2), K144XV with REF Lock option and all is well without doing the KREF3 modification. I guess this is an it either works or it don't situation. With respect to the post about off frequency, not a simple answer. Firstly accuracy and resolution or precision are not to be confused, one doesn't imply the other. The K3 display may read to 1Hz but that doesn't mean it is accurate to 1Hz. If folks in a net all set their various digital displays to the same frequency it doesn't mean they are all on the same frequency. As has been mentioned there is a perfectly good method of adjusting calibration detailed in the handbook using WWV. It doesn't directly tune or otherwise adjust the reference oscillator (TCXO) but lets whatever is involved with controlling the synths what the reference frequency really is so that the error can compensated for mathematically. That is my understanding. I have been using this WWV method for the past nine years and was convinced that the TXCO was probably drifting with age and have often said that the CONFIG: REF CAL is not a one off adjustment. This unfortunately turns out not to be the whole story. Now it has to be said, the TXCO does drift, shock, horror. The high stability option is described as being +/-1ppm but actually seems to achieve 0.5ppm, at least mine does. How do I know this? I don't have a frequency counter, or at least I didn't and in fact you don't need one as will be discovered later. What I do have is the K3 external reference frequency lock option fitted and recently purchased a Leo Bodnar GPS disciplined reference clock which provides the necessary 10MHz drive for the ext ref option. With a new toy you have go to play and what I discovered follows. With the GPS source up and running, turning on the K3 and enabling the external ref feature the REF CAL measured TXCO frequency will be displayed, counted by the ref lock module. This frequency will be seen to change with warm up. My TXCO has a positive drift of approx 26Hz+/- a couple in the first three minutes, for the next 30 minutes it drifts a further 6Hz. Thereafter it slowly drifts until after four hours it tops out at +57Hz or so and by this measurement method stops drifting. However, there is more. At the same time as noting the REF CAL frequency every minute, for the first hour, I also recorded the front panel (FP) temperature. This started at 23C and over the measurement period increased to 38C. It was observed that the rise in FP temp and the drift follow a similar trajectory. As would be expected. I have monitored the REF CAL frequency for a couple of months now and note that the TXCO drift on my unit always maxes out at more or less the same reading. I have reached the conclusion that if at least two hours of warm up are allowed and a WWV cal operation is then performed you will be in a pretty good place with respect to total drift and subsequent overall frequency (dial) accuracy. It is easy to discover the pattern and extent of the drift of the TXCO in your K3 without any external measuring equipment, external ref locks or such. 1. From cold tune to a WWV frequency you will be able to receive reliably for a few hours. Higher the better. 2. Wait 5 minutes or you will be chasing a moving target. 3. Perform a REF CAL and note the reading. 4. Perform a REF CAL every half hour, less if you feel like it and note the readings. 5. Eventually the reading will really slow down and more or less stop changing. 6. Choose a reading that indicates that the bulk of the drift has happened, (1-2 hours) 7. Set REF CAL to that reading and sleep well. Good enough for HF. Given the highest and lowest frequency readings a further experiment can be performed to discover the consequences of the TXCO drift on dial accuracy. It only takes a few minutes. 1. Set REF CALL to the lowest recorded frequency and tune the K3 to a stable test frequency, I used my XG3, note the "dial" reading in fine frequency display, 3 digits after the decimal point. I used the CW auto spot feature to do the final tune. 2. Set REF CAL to the highest recorded frequency and retune the K3 as above noting the "dial" frequency. The lowest to highest REF CAL frequency is the total TXCO drift in Hz. The lowest to highest "dial" frequency will indicate the consequence of that TXCO drift in Hz. You will be pleased to note that the two do not match. The K3 tuned frequency change is rather less than the TXCO drift. Reset the REF CAL reading to that you previously chose to be your K3's sweat spot. The above shows why I was wrong in relating the REF CAL frequency changes to TXCO ageing. In reality it all comes down to warm up time. I hope this was worth the read.

Note that the standard oscillator takes two hours to stop drifting instead of four. Also the TCXO isn't. There is no temperature feedback implemented. One is essentially seeing the stability of the native oscillator. Too bad feedback isn't implemented, I'd bet a lot of drift noted would disappear. Not discussed is the "last digit" syndrome. Only believe the last digit displayed if you can check that it is accurate. With the standard synthesizers, as one tunes up the band the true frequency deviates from the displayed by up to +/-4 Hz. There are times when one tunes up and the RX actually goes to a lower frequency. Same problem when tuning downwards. In other words, there is electronic "backlash". One has no way of knowing which point of this sawtooth error curve you are when choosing to calibrate to WWV. This is essentially fixed with the new synthesizers. 73 de Brian/K3KO On 4/9/2017 16:16 PM, Mike Harris wrote: > Immediate apologies, this is a tad long but hopefully interesting. > > My K3 has the new synths (2), K144XV with REF Lock option and all is > well without doing the KREF3 modification.

This feature was inspired by both the original KX2 field testers and responses to our recent question about additions to the KX line. Having four programmable functions rather than one really helps. The KX2 has fewer switches than the KX3, making it a bit more dependent on the menu for often-used functions. If you?d like to give this new release a try, let me know.

KX2 really is a great radio though, just about everything I thought it would be and more. Staying with her during her recovery when not working but looking forward to her full recovery and my qrp KX2 outings to resume ;-). I hope she will be going with me more often to get out and do hikes/walks.

Looking fwd for this great improvement to be download-redy for the rest of us. I am a new (up to 2 months) KX2 user so the first things I found myself missing is more Pfn buttons, at least 2. Now there going to be 4 of them! So my first set would be PF1 =VOX, PF2= XIT, PF3=BKLIGHT, PF4=PS. Using the radio car mobile a lot I already use the existing Pfn for the VOX in CW mode, and the XIT is the second mostly needed. I will finaly decide on the last two after some more time of variety usage. 73 Linas LY2H On 2017 bal. 9, sk at 21:20 Chuck Guenther wrote: > Beta firmware v. 2.75 works very nicely, Wayne.

I suggest you do so before concluding that your radio is off frequency. Tune to WWV at the highest frequency you can receive in CW mode and zero beat the carrier - you can use CWT if you are not good at zero-beating. Make sure you are zero-beating the carrier and not one of the transmitted tones. The tones come and go minute by minute, but the carrier is always present. Stations that cannot receive WWV can use of of the other standard stations around the world. If your K3 is off frequency, do the Reference Oscillator calibration and check again. 73, Don W3FPR On 4/9/2017 5:42 PM, Dick via Elecraft wrote: > I have a K3 kit that's been back to the factory for repair and alignment, > and a K3S that was factory made and aligned.

Back in the day, Elecraft informed us about that cyclical error problem with the old synthesizer. It would now be good to have a definitive statement about the frequency setting accuracy in the new synthesizer. The same applies to the TCXO error correction by the KREF3 module. Since corrections are applied by rewriting the declared value of the 48MHz reference frequency, presumably this can still only be changed in 1Hz increments. A related question (raised by Don's post, just in) is the magnitude of any difference between the displayed sidetone pitch and the actual value within the synthesizer? 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >brian >Sent: 09 April 2017 18:33 >To: elecraft at mailman.qth.net >> 'Elecraft Reflector' >Subject: Re: [Elecraft] K3 slightly off frequency > >All true.

In fact, that is one easy way to define RIT. During RX, the K3 will show the actual frequency (at your chosen sidetone pitch) that you are listening to. But if you have RIT or XIT turned on, the transmit frequency will be different than the receive frequency. Hopefully your perception of "zerobeat" means that you have tuned the signal until the tone is equal to your sidetone pitch (SPOT) and not an attempt to tune to zero frequency (which is incorrect and will produce 'strange' frequency readings). 73, Don W3FPR On 4/9/2017 6:14 PM, Mel Farrer wrote: > I dial in the frequency, zerobeat, I want and use the pitch or RIT to > get the "sound" I want. > > Mel, K6KBE > > > ------------------------------------------------------------------------ > *From:* Don Wilhelm > *To:* RLVZ at aol.com; elecraft at mailman.qth.net > *Sent:* Sunday, April 9, 2017 3:06 PM > *Subject:* Re: [Elecraft] K3 slightly off frequency > > Dick, > > Another thing to check (and I assume CW operation) - make sure you are > listening at the same pitch as you have set in the sidetone pitch. > > 73, > Don W3FPR > > On 4/9/2017 5:42 PM, Dick via Elecraft wrote: > > I have a K3 kit that's been back to the factory for repair and > alignment, > > and a K3S that was factory made and aligned.

Note that speech able people who lose their hearing slowly also loose the ability to talk properly. If you are hard of hearing you might talk too loud; happens to me on occasion; its just your neural feedback loop doing "human ALC", as it were. For those who operate voice modes on satellites the time delay produced on monitoring your transmission with a full duplex station can get madding. The delay is caused mainly by RTLT (round trip light time) which is the time delay for the signal to travel round trip from the satellite. For HEO (high Earth orbiting) satellites the range gets to a point to experience significant delay in your voice monitored in the downlink Rx. On AO-10/13/40 it could be challenging to talk properly hearing your own voice delayed. I would sound like: hello-ello, how-ow, are-re, you-ou. Say that at a normal speaking rate and you will get the idea what it sounded like. Full duplex operation is quite useful in satellite operating: 1. Avoid talking on top of another station 2. Making frequency adjustment for Doppler 3. Verifying you have an adequate uplink into the system to be heard. Many learned to compensate (mentally disregarding their own voice - which is difficult), or turning down the Monitored audio level when transmitting.

Hopefully your perception of "zerobeat" means that you have tuned the signal until the tone is equal to your sidetone pitch (SPOT) and not an attempt to tune to zero frequency (which is incorrect and will produce 'strange' frequency readings). 73, Don W3FPR On 4/9/2017 6:14 PM, Mel Farrer wrote: > I dial in the frequency, zerobeat, I want and use the pitch or RIT to > get the "sound" I want. > > Mel, K6KBE > > > ------------------------------------------------------------------------ > *From:* Don Wilhelm > *To:* RLVZ at aol.com; elecraft at mailman.qth.net > *Sent:* Sunday, April 9, 2017 3:06 PM > *Subject:* Re: [Elecraft] K3 slightly off frequency > > Dick, > > Another thing to check (and I assume CW operation) - make sure you are > listening at the same pitch as you have set in the sidetone pitch. > > 73, > Don W3FPR > > On 4/9/2017 5:42 PM, Dick via Elecraft wrote: > > I have a K3 kit that's been back to the factory for repair and > alignment, > > and a K3S that was factory made and aligned.

There we agree ... where the monitor level is set to be usable in the headphones, it does not cause a feedback issue even if the speakers are turned on.?

In other words, your statement "match my K3 frequency to his" is not sufficiently informative. It all depends on how you match his frequency. What the dial says on his transceiver is not relevant, the only thing important is what you are hearing. Would it not be better (and easier) for you to change the PITCH of your SPOT tone to the pitch you like to hear? That means there is no need to use RIT most of the time - if you tune the incoming signal to that same tone, you will be on the same frequency. The K3 then uses that pitch as the center of the filter passband (unless SHIFT is set somewhere other than default) and is the pitch used for zero beating. The normal use of RIT is when you have called CQ and a station comes back to you not exactly on your transmit frequency - RIT can then be used to tune that station in and not create a situation where the QSO "walks up the band" with each transmission - your TX frequency stays put and the other station's TX frequency also stays put. 73, Don W3FPR On 4/9/2017 7:04 PM, Mel Farrer wrote: > Good question Don, Check out on this.

There we agree ... where the monitor level is set to be usable inthe headphones, it does not cause a feedback issue even if the speakers are turned on.? However, if one is using low sensitivityheadphones with the speakers turned up high *and* high mic gain, one can cause feedback or echo.?

I heard a station calling CQ and said to myself, that's Dave's (W5UN) frequency. Sure enough, it was Dave calling CQ. So I tuned off him and heard another station calling CQ. I listened and was surprised to hear Dave again. I tuned back to the other frequency and Dave was still there, albeit with a different delay. It finally dawned on me I was hearing him off the back of the antenna on tropo and off the moon from the front side. Doppler and the time delay made it sound like two different stations.

The internal resistance doesn't add voltage drop without the load present. There are instruments out there that assess battery health. Can you get access to one?

Advantages would be the longer ultimate life of LiFePO4, a voltage closer to 14V fully charged and a higher voltage toward the end of charge than the 3S LiIon pack, allowing higher wattage output as the pack depletes. I've done this myself with the KX1 with very satisfactory results. This would be a really nice substitute for the NiMh cells in the KX3 too. I understand that finding a 4S LiFePO4 pack in a form factor that maximizes use of the radio's internal space might be difficult, but I can wish.

Matt's suggestions are good ones.? You should also, as soon as possible, take the cells out of the holder and do two things: 1.? Inspect each cell for damage to the plastic cover that is around each cell.? Look around the positive terminal for damage that plastic cover.? That can cause a short in that cell.? Check the side of each cell for damage caused by a battery holder attach screw that is too long.? If the builder used the wrong screw when attaching the holder, it can extend beyond the surface of the battery holder and damage the plastic causing a short to ground.? Elecraft issued and alert to check the holder for the proper screw length.? I can't emphasize enough that damage to the plastic covering is unacceptable.? I don't think that this is the most likely cause since the cells return to a reasonable voltage while resting. 2.? Measure the voltage of each cell.? After charging and resting for an hour or so, they should all be within about 0.1 volt of each other.? A little more variation is OK for cells that are partially discharged.? Be careful when probing the positive terminal.? It is easy to short the cell if the plastic cover does not extend completely around the top of the cell.? That falls under item 1 above. These are good steps to take a few times per year.? Matt's suggestion of looking at the current draw is important.? That should help isolate the source (radio vs. cells) of the problem.? It is possible that the wrong screws were used somewhere during the radio's build and one extends too far causing a short in the supply.? Elecraft supplies all the proper screws for the job, but it is easy to put the wrong one in the wrong place.? I don't know what your situation is, but you may want to consider returning the radio to the builder for repair. FYI, I have never seen a bad Eneloops from the factory, but it is possible.?

I will repeat mine for contesting, DXing, and casual operation. Three lowest bands maximum cut. Fourth band cut 6 dB. 3-6 dB boost of top two bands. Then get signal reports from a trained listener, who has his/her RX set for wide IF bandwidth. Depending on your voice and the mic, that 4th band may need more cut, and/or those top two bands may need more or less boost. AFTER EQ has been set, turn CMP down to zero and set mic gain per the manual. THEN, with the display set to show Compression, increase CMP to the point where you see about 10 dB of compression on voice peaks. Why do I recommend the same settings for contesting, DX, and casual operation? Because these settings increase talk power by nearly 13 dB, equivalent to your 100W rig driving a 2kW amp, and your 10W radio like a 200W radio. That difference gets you 13 dB higher above QRM and noise, and has the effect of minimizing the effects of QSB.

You may be confusing CWT with Text Decode - they are different things. CWT is a tuning indicator only which displays how close your VFO is tuned to your sidetone pitch. For Text Decode, read the Text Decode and Display section of the manual on page 29. Note that Text Decode is only for CW, PSK D and FSK D. It does not work in DATA A or AFSK A data submodes, those are normally used with a software application in soundcard data modes. 73, Don W3FPR On 4/10/2017 5:03 PM, hb9eyq wrote: > New KX2 owner.

Press and hold the TEXT button and you will see DEC OFF in the VFO B display. Rotate the OFS/B knob to RX THR 1. Press any key to exit. The CW will now print in the VFO B display. You must tune in the CW signal so that it is centered on the CWT mark for best performance. Briefly pressing the KYR-SPT/MIC knob will do that.

I had never heard of this product, so googled to find the website. The description of this mic is in conflict with itself -- it first calls it a "noise cancelling mic" but down the page calls "uni-directional." VERY different -- noise cancelling works on the basis of distance -- two perfectly matched capsules, out of polarity, reject sound that isn't within an inch or so of the mic. In general, they sound awful. Unidirectional mics are ok but not great -- they suffer from proximity effect, which strongly boosts low frequency sounds, wind, breath pop, and vibration (like handling noise). I wouldn't change my advice, which says start here and get reports. And that settings for that 4th band and the high boost will depend on your voice and the mic. With this mic, you're more likely to want greater cut of that 4th band. > I realize I have to test this myself and get some feedback on quality and punch but if you had any thoughts I'd appreciate hearing them. I'd be happy to run a sked with you to help you judge settings.

Bands 5 and 6 should remain at 0. Actually, the settings are not very different. I'm starting from 0, and using relatively little boost. By boosting the midrange, their low cut relative to mid-range is pretty similar, and their boost of the two higher bands is similar, relative to the midrange. BUT -- one thing we learned in pro audio is that CUT EQ is better than BOOST EQ, primarily because using too much boost can cause the signal chain to run out of headroom (that is, clip). And remember I said 3-6 on the top two bands, and get reports. 73, Jim K9YC On Mon,4/10/2017 3:35 PM, john at kk9a.com wrote: > I am trying to compare the Heil contest settings with yours, 5 and 6 are > not mentioned in your post.

You can see a graph comparing his recommended contour to Heil?s at my blog post (link below). I plotted all the contours posted to the Elecraft mailing list to compare them.

The description of this mic is in conflict with itself -- it first calls it a "noise cancelling mic" but down the page calls "uni-directional." VERY different -- noise cancelling works on the basis of distance -- two perfectly matched capsules, out of polarity, reject sound that isn't within an inch or so of the mic. In general, they sound awful. Unidirectional mics are ok but not great -- they suffer from proximity effect, which strongly boosts low frequency sounds, wind, breath pop, and vibration (like handling noise). > > I wouldn't change my advice, which says start here and get reports.

Thank you. Perfect guidance for me. I was missing the CWT enable via the menu and the rotation of VFO knob B to select THR 1. I was confused that CWT was on for PSK without having to take an extra step to turn it on but not for CW. Thanks for the CW auto tune tip. I am quite happy with the decode quality. Would be cool if you could temporarily switch the entire screen to display decoded text, if you turn away for a brief moment you'll miss the decode. Connected a PC with the USB cable and decoded text displayed fine. I have a small OLED display and an Arduino, maybe I'll build an extended decode window. 73 HB9EYQ Larry > > On Apr 11, 2017 at 1:52 AM, wrote: > > > > Larry -- To receive CW text, press the MODE button to select CW.

You should also, as soon as possible, take the cells out of the holder and do two things: > 1. Inspect each cell for damage to the plastic cover that is around each cell. Look around the positive terminal for damage that plastic cover. That can cause a short in that cell. Check the side of each cell for damage caused by a battery holder attach screw that is too long. If the builder used the wrong screw when attaching the holder, it can extend beyond the surface of the battery holder and damage the plastic causing a short to ground. Elecraft issued and alert to check the holder for the proper screw length. I can't emphasize enough that damage to the plastic covering is unacceptable. I don't think that this is the most likely cause since the cells return to a reasonable voltage while resting. > 2. Measure the voltage of each cell. After charging and resting for an hour or so, they should all be within about 0.1 volt of each other. A little more variation is OK for cells that are partially discharged. Be careful when probing the positive terminal. It is easy to short the cell if the plastic cover does not extend completely around the top of the cell. That falls under item 1 above. > > These are good steps to take a few times per year. Matt's suggestion of looking at the current draw is important.

Elecraft supplies all the proper screws for the job, but it is easy to put the wrong one in the wrong place.

An external pan adapter is distracting. Different strokes for different folks. I'm quite happy with the P3 amd P3/SVGA. I really like the flexibility of layout on my operating desk that having the P3 in a separate unit that I can set alongside the radio or on top of it. For my desk, it works best sitting on the left side of the top of the K3.

I have had integrated pan adapters before and I even have one now on my backup rig (IC-7300) and the battle for space is too much I think. Separate allows the dedication of display space which is nice for a panadapter. However, a KX2 or KX3 with a modified display option for a panadapter would be nice if it could be done well. Of course, it would not be color coded like the P3 or PX3 but it would be useful for spotting signals on the band. My Icom 706 had a kind of very limited scan panadapter and its major failing was the visual display interface was not done well. My operating style with KX2 is very different than my home station K-Line. Maybe something on the lines of a signal spotter. Of course, with my KX2 (and also with my former KX3) I am CW only and this feature would be nice to have. Yes, the KX3 has the PX3 but carrying along even that extra piece of equipment out into the field for portable ops is not something I would do. I used just my KX3 (now KX2), LiPO3 battery, and antenna (which could be anything or my Budipole). 73, phil, K7PEH > On Apr 13, 2017, at 8:23 AM, Jim Brown wrote: > > On Wed,4/12/2017 7:32 PM, Dan Baker wrote: >> An integrated pan >> adapter into the face of the radio is much better than an external unit. >> You see the whole picture at once.

I am using a K3 and an Asus u7 sound card (Windows 7). However, I have run into a snag with respect to ALC. When I run WSJT-X, everything works exactly as expected. During transmission I easily obtain four solid ALC bars (with the fifth flickering). The same settings do not work for JTDX. In fact, I am not able to find any settings (using the sound card control panel, K3 mic gain, or JTDX pwr slider) that provide four stable ALC bars. At many settings the ALC indicator pulses rapidly from 0 to a level that depends on the settings I choose. The ALC indicator stabilizes only if I push input levels so that the indicator reads 6 or 7 bars. I have done all of the WSJT trials in test mode ? I?m reluctant to send anything to the antenna until I figure out what I?m doing wrong. Questions: Has anyone on the list run JTDX on their K3 and seen this problem? If so, were you able to overcome it? What is happening to make the ALC indicator pulse? Depending on feedback here, I?ll post to the JTDX list next.

Since this is the Elecraft list, and we see deals on solid, used K3's, that's a good recommendation. But if we're really talking "first radio" then any good clean semi-recent HF rig would do nicely. The K3 is more radio than the typical "entry level" rig from KenYaeIco, and one of those would be good enough.

If not, you should be. It turns off compression and sets the equalization flat. What you are seeing could be the result of using SSB with compression turned on. Secondly, use the LINE IN - there is likely too much gain if you are using the microphone input. Then set the LINE (MIC knob) gain on the K3 to about mid-range (which gives more resolution than with the gain at either end of the scale) and then use the soundcard slider and possibly the application "power" control to obtain the right number of bars on the ALC meter. It is strange that the JTDX application needs different settings than other soundcard data applications. That certainly points to some peculiarity (or error) in the software. 73, Don W3FPR On 4/13/2017 3:13 PM, Samuel Cartinhour wrote: > I recently decided to try JTDX (v 1.7.0), a derivative of the popular WSJT-X software by Joe Taylor.

In fact, I am not able to find any settings (using the sound card control panel, K3 mic gain, or JTDX pwr slider) that provide four stable ALC bars. At many settings the ALC indicator pulses rapidly from 0 to a level that depends on the settings I choose.

Why would you want to do that? WSJT in all of its forms is K1JT's invention, the code is written by a team of programmers under Joe's direction, and is under constant development to improve its performance and incorporate new digital modes optimized for different purposes. The latest released version (fully compiled, ready to run) was released about six months ago, and I'm seeing greatly improved decoding (occasionally as low as -28 dB) and even two decodes on the same tone frequency! In-progress versions can be downloaded from code form, but must be complied by the user. No fun unless you're a computer geek. :) This is what K1JT wrote on the WSJT Developer's email reflector a month or so ago to the JTDX author. Jim K9YC - - - - - - - - While I have your attention, I must remind you of obligations you assumed under the GNU General Public License (GPL) when you copied the source code of WSJT-X, made some changes, and renamed it as "JTDX vXX.X ... by UA3DJY". 1. Compliance with GPL requires that a derivative work (such as JTDX) must be licensed in a compatible manner. Just saying "It is open source software distributed under the GPL v3 license" is not enough. Apparently a significant fraction of JTDX distribution takes place from the web sitehttp://jt65-dx.com/download/wsjtx-ua3djy.html . 2. I see nothing on that web site mentioning any license requirement. 3. I see a JTDX screen shot in which the main window title is given as "WSJT-X v1.7.0-devel JTDX v16.6 ... by UA3DJY." We have never released a program called "WSJT-X v1.7.0-devel", so I would not expect to see such a designation on a derivative work. 4. Describing JTDX as "by UA3DJY" is surely misleading, and a violation of the copyrights on our code. Probably >90% of code in your derivative work was written by someone other than yourself. 6. Finally: if you were truly committed to the Free Open Source Software (FOSS) philosophy, I would expect your development work to be organized in a way so that can give back to, as well as take from, the amateur software development community. I can see no evidence that you are doing this, for example with an open source-code repository. -- 73, Joe, K1JT From eric_csuf at hotmail.com Thu Apr 13 17:26:21 2017 From: eric_csuf at hotmail.com (Eric J) Date: Thu, 13 Apr 2017 21:26:21 +0000 Subject: [Elecraft] Help me choose my first HF rig In-Reply-To: <03705eff-a9c3-20a4-3742-76fa8e4559c6@ColdRocksHotBrooms.com> References: <4202DCBB-44D0-4750-8067-B084CDAC1EFD@wunderwood.org> <2C6BDAD9-EFC3-4E8C-9CA6-D2924693C797@portcredit.net> <03705eff-a9c3-20a4-3742-76fa8e4559c6@ColdRocksHotBrooms.com> Message-ID: Best advice so far, Lynn.

I missed the original posting. Did the person who is looking for a rig say anything about their budget? The K3 may be a very good radio but I wouldn't be inclined to reccommend a multi-thousand dollar radio as a first rig unless the person has money to burn. I would suggest the person look for a second hand radio that would be closer to the $1,000 or under price range. If they want to stick with a radio that is less likely to have problems they could pick up one of the K2 or K2/100 radios that come up for sale now and then on this list. -- Cheers!

Get a rig and get on the air. In some ways it's sad that Ham rigs have become so sophisticated and cost enough that most Hams need to think in terms of resale value. There is a Ham I used to chew the rig with on 40 CW regularly who saved from his small fixed income for a years to replace his HW-8 with a new 100 watt rig. Dang! He was happy with the new rig. Then I worked him again a few weeks later and he was back on the HW-8. I asked him why. It seems he knew a Ham nearby who was on also a small income and lived alone. His rig died and the cost to repair was prohibitive. Rather than leave him off the air my friend made him a gift of his new rig and dusted off his old HW-8 again.

Hams helping hams! May that not be forgotten - ever. We have many stories that indicate that we do just that. I hope that spirit never dies out. If I may share my early ham days, I was "taken in" by the local ham club - a group of less than 20 members in a small town in Ohio. They and their counsel got me started, and analyzed my problems with the first transmitter that I built. I cannot repay them directly because most of them are SK, but I can pay back to the amateur community at large in remembrance for what those hams did for me. Their encouragement led me to a BSEE education and a career in electronics and design that I would never have anticipated as a teenager. I am not one to sell the gear I have purchased over the years, so I have loaned some of my excess transceivers to new hams just to get them on the air, particularly on HF. I do not regularly sell my radios - I leave that to my heirs, so I have some of my older gear available for long term loan - of course that is normally to locals, but I could consider someone particularly needy in a more remote location if I were asked. So for an HF beginner, look around at your local ham clubs and see if there is someone who has excess gear that can be available to use until you can make up your mind about the ultimate station that you would like to put together. Make no mistake, I believe that an Elecraft station is great for beginners and older hams alike, but if you have questions about what will be "best for you", that takes a bit of experience to determine what you will really need. As I have stated before, a KX-Line will do most everything a new ham can want for HF operations (and more), so I don't think you can go wrong with an Elecraft station as your first ham radio investment - it is an investment that can last you for many years and serve you well in the meantime. 73, Don W3FPR On 4/13/2017 11:34 PM, Ron D'Eau Claire wrote: > I agree.

As a comparatively newer ham (licensed in 2009) I struggled a bit when trying to decide on an HF rig. After more than one conversation with Don (at local NC hamfests) I opted for the K2, mainly because I like to build things. You can't get much more hands-on than the K2... it comes as boxes of electronic components! Of course if that is not your thing, then you can pay others to put it together. I used the K2 regularly until 2016, when I finally sprung for the K3S (kit, of course). Although not a kit in the sense of the K2, it's more like building a computer. Now the K2 is sitting quietly, waiting for the next Field Day outing. I occasionally turn it on, just so it won't get lonely. As those who know me have heard me say many times, I am definitely not a contester, I am a casual operator. I am still figuring stuff out about the K3S, but it is a fantastic piece of engineering. Yes, it is more expensive than a basic Yawoodcom. But the performance is head and shoulders above most rigs. And the support from both the factory, and found here on this list, cannot be beat. To the OP: Buy quality and only cry once. :-) David AJ4TF -- View this message in context: http://elecraft.365791.n2.nabble.com/Re-Help-me-choose-my-first-HF-rig-tp7629258p7629282.html Sent from the Elecraft mailing list archive at Nabble.com.

This thread is getting pretty long but I can't help but chime in. If money is an issue (i.e. you're not part of the 1%), then I think buying a used rig is a great way to go. If you don't like it or decide to upgrade then you can sell it for close to what you paid for it. Think of it as renting a radio while you get some operating experience. After you've been on the air for a year or so, you will have a much better idea of what you want and can make a more-informed purchase. Something like a used K2/100 would make a great starter rig.

Since the SGC company was just a 20 minute drive from my home I decided to go there and see if I could find someone technical to talk to. I did talk with one of the technicians. What I learned was, most people who use this Amp mobile usually use a second battery to run the amps current demand of 40 amps with peaks up close to 90 amps for key down full power. The assumption is that the duty cycle is low enough to allow the Alternator to maintain charge on the battery simultaneously with providing raw power itself. The implementation though required heavy duty wiring from the main vehicle battery/alternator source with diodes in line that are obviously high-current and thus pricey. Also, some vehicles may have need to upgrade their Alternator although on my 3/4 ton pickup truck, I already had an oversized alternator in place. I had my truck wired to handle the current draw and this was done at one of those ?car? electronics shops who do this regularly for guys (usually guys) who want big hunking audio amps in their cars that also demand high current power. So, this kind of installation was a regular day at work for that store (called Car Toys, Washington State and maybe other locations). However, I never did buy the amp ? kept putting it off and stayed with 100 watts of power and eventually (two years ago) opted out of mobile operation in favor of portable operation and instead of 500 watts, primarily 5 watts or whatever I would put out with my KX1, KX3, and now KX2 (but have not had the KX2 long enough to work in the field portable). But, the idea of running the KPA500 because it runs off of 120 VAC is not something I would ever try just because of the hassle. I would get another suitable 500 watt class amp if I were still into that and leave my KPA500 fixed in the shack. Not sure if the SGC SG-500 is still available though, I heard a while back that SGC had stopped production but it still appears on their web site http://www.sgcworld.com/ampProductPage.html. 73, phil, K7PEH > On Apr 14, 2017, at 9:00 AM, Mike Smith VE9AA wrote: > > Big fan of mobile ham radio here...Have always run 100w. > > Would like to do more.

The home station was equally impressive, although until Collins introduced their noise blanker, was primarily used to transmit bulletins or code practice. The mobile rig was the answer to the noise problem before that.

Back then I lived in the land of the "California Kilowatt" (Southern Calif.). They mounted outboard generators on their car engines to handle the power demand. Adding filaments, etc., a kW mobile station might require 1.5 or 2 kW of d.c. power to run it.

It isn't mobile, but it could be with the same hardware. The method I use is a 115 volt AC inverter that runs off a 12 volt battery. I use the Xantrex Prosine Pure Sine Wave 1800 watt inverter. https://www.amazon.com/Xantrex-Technologies-1800PS-1800-Watt/dp/B0000225DC This unit is crystal controlled and does not generate much RFI at all. It does require huge input wiring and some substantial battery capacity. I see 75+ amps on CW peaks, and to keep the regulation OK, the stranded wire is about 3/4" in diameter and very short between the battery and the inverter. I also have a 200 amp safety fuse in line as well. It has worked great with two 275 AH solar batteries and you would not even know you were running on batteries. The output of the sinewave inverter is quite solid at around 117 vac. It has been in use for a few years. No problems. I would run two moosey batteries besides the auto battery and install a new alternator in your vehicle for charging the batteries. I use solar panels here for charging, and on a sunny day see about 25 amps charging the batteries between transmissions. I can run all day on a sunny day, and about 10 or maybe 12 hours casual operating at night with just the batteries. It is pricey, but cool. I use the KPA-500 on six meters too and have been able to catch openings and work plenty of DX with the solar power.

The truth of that assumption, coupled with how much shielding a vehicle actually presents, is worth considering. Until the RF Exposure business came along, no one considered safety for those outside the car. Less and less body-metal, roofs made entirely of glass, more electronics both on and inside human bodies (over and above the vehicle's electronics), the close proximity of the antenna . . . all of which, in my opinion, argue for a re-think of high-power mobile operation. In the 1970s I greatly enjoyed mobile CW with an FT-101E until my first child started occupying the rear seat. After she came along, I opted for no further mobile work of any kind, at least when she and her siblings were in the car. I'm not a geneticist, but neither am I willing to push my luck with the gazillion of cell-divisions going on every second in a child's growing body.

When I take my 2011 Ford Focus through the car wash, I put the mag-mount VHF antenna inside the car but it is still connected to the radio. I have no problem picking up the usual 2- and 3/4- meter repeaters that way.

This was modular, 16' x 20' x 10' and composed of 2" thick particle board, clad on both sides with tin-plated sheet steel. Because I needed to be able to move a rack mounted test position with a table top in and out, I specified a four-foot wide door. The door was constructed similarly with a brass frame around the door and was prehung in a brass jam and massive hinges. It was installed using a forklift to position it while the fasteners were tightened. The jam had a continuous channel around the periphery that housed a double row of beryllium-copper finger stock backed up by conductive foam. The door frame had a brass "knife-edge" around the periphery that drove into and was pinched by the finger stock in the jam. On of the specs that I remember was 120 dB of isolation at 10 Ghz. We measured this by setting up a source with a horn antenna on a tripod outside the room with another horn and LNA into a spectrum analyzer inside the room. We normalized the path with the door open and the horns aligned and then closed the door and measured the difference. It made 120 dB, but just barely; this is not a trivial achievement. To drive home the necessity of maintenance, the vendor engineer said, "Watch this." He took a dollar bill out of his wallet and laid it across the finger stock and then closed the door. I don't remember the exact number but it was yuge; the attenuation went down 30 or 40 dB just from breaking the connection of the knife edge with the finger stock over the width of a dollar bill. (For what this room cost, he should have been using a c-note.)

For cars going the same direction as you, you as the control operator, have to make sure you don't irradiate anyone else around you beyond the limits.... Besides installation accommodations, you can control exposure by manually maintaining a sufficient "bubble" around you during transmission (extended transmission... whatever the math tells you. I don't have a feel for where we are generally "safe" mobile... For myself, I would have to do an actual test as installed and measure/observe and plot. Another excellent question.... of course you should ask. Not a trivial engineering task IF you want to do it correctly. :) ______________________ Clay Autery, KY5G MONTAC Enterprises (318) 518-1389 On 4/14/2017 2:39 PM, Lynn W.

The smaller blockages are probably deemed a minor inconvenience, especially if they're out inthe countrysideor in unpopulated areas. I used Sirius in the early 2000s, and used to experience regular dropouts of 4 seconds in several locations on my commuteto/from work. Each of these areas was under a highway or freeway. Not sure if your tunnel was private or not. If it was, it wasn't covered by surface transmitters unless by accident. There is a tunnel in LA that basically runs under LAX, and I never lost signal there. It's probably hit or miss on what's covered terrestrially. XM (I believe) bought Sirius out, sometime in the last decade. Both services operate on the abandoned telco S-bandif I understand correctly. I hear XM isn't doing so well financially, but that was probably a couple of years ago. May not be current on this. 73, matt W6NIA On 4/14/2017 8:47 PM, Fred Jensen wrote: > Semi-related curiosity regarding shielding. My wife's car has > Sirius/XM radio.

I occasionally car pool to ham events with a neighbor in his high end VW. He bought the satellite service, and we sometimes listen to it. It drops out with foliage and under overpasses. Sound quality is so bad that it's hard to listen to any form of acoustic music.

Message-ID: <000001d2b5cc$6dfdc870$49f95950$@tampabay.rr.com> Shameless Promotion but interesting story: Two years ago in the Florida QSO Party, our local "Mad Scientist" and mobile operations God Chris, NX4N, decided to do something that had never been done before: A Multi Multi mobile entry! In his Chevy Suburban, we had four radios: A K3 in the front seat (K0LUZ), a Pro2 (W4BP) and a K3 in the second row (K4KM) and me with a K3 in the third row. 20m, 40m, 15m and 10m in that order. Chris did all the driving. It was an all CW operation. Lots of filtering and coax stubs installed. Four separate antennas on the corners of the roof. Four separate computers. The KX3 was feeding a KPA500 in the back of the Suburban which turned it into a 100w radio. Power supplies and other sundries were installed in a bread rack in the back and secured by Bungie cords. Feeding power to all of this was a Honda 2kW generator with an external fuel tank mounted on a carrier attached to the trailer hitch. The generator was covered by a plastic tub held on to the hitch carrier with Bungie cords. This cover was for rain abatement. The cover was adorned with special vents on the side. Yes, crazy and a gray area of mobile legality, But all of us survived to tell the tale. And it was Great fun! And I remember working OM2VL at almost every single county line. It's the only time I have seen a KPA500 mobile. I have since bowed out of this glorious extreme mobile engineering achievement. But it continues with others to this day. And it will be on this coming weekend in the Florida QSO Party's 20th anniversary celebration. The call sign used by this intrepid crew is K4OJ (in honor of FCG Founder Jim White (SK)). Look for them this coming weekend! Lu - W4LT (W4I in the FQP - Spell "F-L-O-R-I-D-A S-U-N" with our 20 "letter multiplier" stations -2 for each letter - for a special certificate!)

If you run the impedance vs spacing calculations, you'll see the spacing doesn't make a whale of a lot of difference. I don't have the numbers here, but I switched from 1/2 of a BIC pen body (hole centers about 2" apart) to some ceramic spacers another ham gave me a box full of. The new spacers had centers about 3.2" apart. I had to re-tune the ATU on most bands, but everything continued to work fine. From (a tired old) memory, the impedance varied from about 450 ohms to something like 600 ohms, but let someone on a computer run the calcs for this. It just didn't make enough difference to worry about, but did change the ladder feed's impedance. This antenna is a doublet about 180' long at 45 feet height, fed with the ladder line (61' of it, from memory). The ladder line terminates into a 1:1 balun (Elecraft BL2) and the last 20 feet is LMR400 low-loss coax back to the station's antenna switch. It continues to work just as well as with the earlier ladder spacers. 73, matt W6NIA On 04/15/2017 09:39 AM, Richard Fjeld wrote: > Forgive me for the OT, but there are many antenna people here above my > pay-grade. > > I need to replace the spacers on my ladder line.

Great post, Colin. > RF fields around the antenna will be high and most mobile antennas have a low input impedance. To fully understand EMI risk you need to understand where the RF current will go, and simply put you need to consider the antenna as every conductor in the vicinity of the actual radiator. This is FAR too simplistic a view. The metal body, chassis, and frame serve as the counterpoise for the antenna. These metal parts of the vehicle are the return for antenna current and for the field generated by the antenna. This makes them part of the antenna, they are carrying as much power as that vertical radiator we CALL the antenna, and current will be distributed around the vehicle's metal parts just as in any other antenna. The only difference between current distribution in the vehicle and in a wire is that the shape of the vehicle is very different from a wire, so that modeling it is far more complex. This current can easily couple into vehicle wiring running in proximity to that current.

The firmware can be found at: http://www.elecraft.com/KX2/kx2_software.htm There?s one minor issue; using PF1-PF4 with some menu entries (like TIME) doesn?t allow use of the numeric keypad digits. This will be corrected in the next release. 73, Wayne N6KR * * * KX2 MCU 2.75 / DSP 1.49, 4-3-2017 * FOUR PROGRAMMABLE FUNCTIONS: The KX2 now has four programmable functions, PF1-PF4, rather than one. These can be used to quickly access often-used menu entries. To set up a programmable function, locate the desired menu entry, hold PFn, then tap any of ?1? through ?4?. Exit the menu. From then on, the menu function can be accessed using the associated PFn switch. If a menu entry has only two values (such as ON/OFF), accessing it via a programmable function will select the alternate value, then exit the menu immediately. This is especially useful with menu entries such as DUAL RX, VOX MD, ALT MD, and ATU DATA (see rev. 2.73, below). * TWO ATU DATA SETS: The KX2 will now store two full sets of per-band data for the internal ATU (KXAT2). Use the ATU DATA menu entry to select which set to use. Typically SET 1 is used at a home location, and SET 2 for field operation. They can also be used in cases where more than one antenna is available for a given band. (Note: The ATU DATA menu entry has no effect on KXAT100 ATU data, which is already stored separately for each of the KXPA100 amplifier?s antenna jacks. The KX2 can remotely switch KXPA100 antennas using the ANT.X SW menu entry.) * ATU LC NETWORK VALUE DISPLAY: In either the ATU.DATA or ATU MD menu entry, tapping the "ATU" switch shows the present values of L (inductance), C (capacitance) and N (L-network configuration). This applies only to the internal ATU (KXAT2). The displayed data format is LxxCxxNy. is a 2-digit hexadecimal value that, when converted to binary, shows which ATU L or C relays are engaged. shows which side of the L-network the capacitance is on: Nt = TX side, and NA = antenna side. * ATU CLEAR AFFECTS ONLY CURRENT DATA SET: Within the ATU DATA or ATU MD menu entries, CLR (hold of the OFS/B knob) now clears KXAT2 ATU data only for the presently selected data set (SET 1 or SET 2) on the present band. As before, CLR is recommended when using the internal ATU with a new antenna. Once the data is cleared, very few ATU tune operations will usually be needed to cover an entire band. Note: If a KXPA100 amplifier is connected, the CLR operation applies to the KXAT100 ATU?s per-band/per-antenna data, not to the data for the internal KXAT2 ATU.

I have one complaint and one concern. First the activation of the KBPF3A is very vague. It's mentioned in the users manual on page 60 (the configuration menu) but there's nothing that says, while in (CONFIG:KBFP3) that you have to press [SUB] and then select "nor". I double checked the installation manual for the sub receiver and the KBFP3A but there was nothing about activating the General Coverage filters. My concern is; I consider myself as an experienced kit builder but for me, it was a bit difficult installing the Sub-Receiver. The TMP cables were in the way and sub-receiver box was a bit difficult getting the SUBIN and SUBOUT boards to align and mate properly. Someone who is new to kit building would have a more difficult time. The sub-receiver is working great and the one thing I like about it is; it's a clone of the main receiver with FM, AM, 2.8, 400 and 250Hz filters. I wonder how the sub-receiver would stack-up on Sherwood Engineering's test data.

Got back in front of my desktop 'puter and made an Excel worksheet to calculate the characteristic impedance at various spacings and wire sizes. The real variable is the ratio of spacing divided by wire diameter (only the ratio matters). Everything else in the formula is a constant for our purposes. 16 AWG, 1 inchspacing: Zc = 436 ohms 16 AWG, 2 inchspacing: Zc= 519 ohms 16 AWG, 3 inch spacing: Zc= 567 ohms 18 AWG, 1 inch sp: Zc = 464 ohms 18 AWG, 2 inch sp: Zc = 547 ohms 18 AWG, 3 inch sp: Zc = 595 ohms Or for you QRO ops: 3/0 AWG, 9 inch spacing: Zc = 450 ohms. 3/0 (three-aught) is quite hefty, being 0.4" in diameter. Probably overkill for the average Joe Ham. The commercial ladder line I use is 18 AWG with about 0.9" spacing (hard to measure), giving 451 ohms. I think there is a lot of this type in use. Anyway, for the wire sizes and spacings we would normally use, the Zc is nearly the same value, which is all I was saying before. The formulas for all this are pretty well documented at http://hamwaves.com/zc.circular/en/index.html. 73, matt W6NIA On 4/15/2017 10:52 AM, Lynn W.

What made me curious is that twin lead is stated in steps of 150 ohms. IE. 300, 450, 600. I assumed it was to match the impedance of certain antennas such as a folded dipole, etc. Since I understand my loop to be a non-resonant antenna, and using a manual tuner, I thought I'd be okay to change the spacer dims, but I wondered if I was over-looking something.

The calculations I did were for open wire line with air being the dialectric (something like 1.0054). The first ladder line that I used was made from BIC pens, cut in half for about 3" center to center. After that much hassle to put together and raise, when it got wind-blown and torn up, I just started using the HRO stuff. Have only seen really heavy feeds in use at SW BC stations, and only twice at that. Looked like 4 AWG, but might've been heavier. Some of WWVH's curtain feeds lookmuch the same. 73, matt W6NIA On 4/15/2017 3:56 PM, Clay Autery wrote: > Thanks.... > > So, these numbers are for BARE copper, right? > Using insulated wire changes things a bunch.... > > For instance 18 GA THHN/THWN has an approx. dc of 2.35, XLPE has a dc of > 5 or so....

A summary and then it can pass into the archive ... 1. The first of "my" tunnels is in Newcastle CA [between Auburn and Sacramento on the old US40 and Lincoln Hwy route] and was constructed sometime around the end of the 19th/beginning of the 20th centuries. It's not quite 1/4 mile long. There is no visible wire or radiax in it. The hill it runs thru is full of water and you get leaked on when driving thru it, even in summer. 2. In the early 80's, the company I worked for then had a contract to rehab the communications for the Bay Area Rapid Transit system. We used a 300 ohm twinlead with a hollow core about 2 1/2 in in diameter along the ceiling of the tunnels and underground sections. It was 150 MHz land mobile stuff and the twinlead was fed from a combiner that put 5 or 6 transmitters into it [train control, fire, security, etc.] It worked very well. Aligning the combiners [which actually looked a bit like a still [:-) ] was a bear in the equipment spaces in the tube under SF Bay but it worked well. They also wanted 800 MHz simulcast throughout the service area, a requirement probably still waiting for a real solution. 3. Other than under bridges, in canyons, beside heavily forested roads, and in the garage, where it's obvious the path to the satellite(s) is blocked, we don't experience any XM drop outs. She's going to drop the subscription, it's expensive and my new Honda Ridgeline has become our travel vehicle, but she's had it since 2013. 4. I've wondered if there wasn't some sort of waveguide effect in tunnels. For BART, one of the many problems we had with simulcast was that it leaked into the tunnels, even as far as the bottom of the Transbay tube. I don't know the XM satellite frequencies but I thought they occupied some spectrum abandoned by the Cellphone industry. 5. [Bonus Factoid]: The pine forests of the Southeast US are opaque to 800 MHz.

On the newer KSYN3A boards there is a green LED on the top edge of the board that should be ON if the board is working ok. You mentioned a sub RX so you should have two of these boards mounted against the back of the front panel. In any case, if the main KSYN3 board dies, everything acts as you've described. If the sub RX KSYN3 board dies, only the sub RX is affected. So there is a chance you could swap the KSYN3 boards and bring the main K3 back to life at the expense of no sub RX. Just a thought - bit of a pain to swap those boards.

Message-ID: The very best station on Sirius/XM really destroys the beautiful melodious sounds and overtones coming from the banjo. It gives it a watery metal sound. However that does not stop me from listening to it. It is really all about the content. That's why I can enjoy bluegrass on my iphone or XM radio. Nothing coming close to listening live music when you are surrounded by other pickers. So you do not have to bother with finding the perfect speaker or stereo. They can never reproduce what you hear live. Same thing with radio. It is all about the content. This is one reason we enjoy CW so much. The tone sounds like you are in presence of the sending cw operator coming out of our receivers. It only has to reproduce one tone, it's fairly narrow and it sounds live. Jim K9YC I am sure you have good term for this. I don't know what the phenomena is called. Maybe if the speaker was shaped like a banjo that would be a good place to start to reproduce its sound however, then you need another one shaped like a dobro and so on. Not really practical. 73, Dan KM6CQ *Don't sacrifice your hobby for the right house.* I occasionally car pool to ham events with a neighbor in his high end VW. He bought the satellite service, and we sometimes listen to it. It drops out with foliage and under overpasses. Sound quality is so bad that it's hard to listen to any form of acoustic music. Perhaps too much data compression, made worse by any problems with the signal path. 73, Jim K9YC From ron at cobi.biz Sat Apr 15 23:14:52 2017 From: ron at cobi.biz (Ron D'Eau Claire) Date: Sat, 15 Apr 2017 20:14:52 -0700 Subject: [Elecraft] Sub Receiver & KBPF3 In-Reply-To: <1492288020006-7629327.post@n2.nabble.com> References: <1492288020006-7629327.post@n2.nabble.com> Message-ID: <000801d2b65f$9dc00080$d9400180$@biz> Hi Jack: Page 16 of the KBPF3A manual says under the heading "Enable the KBPF3A Module": "Enable the KBPF3A for either the main or sub receiver using the CONFIG menu as described in the Owner's Manual. The KBPF3A will not operate until this is done!" Perhaps I should have repeated the whole procedure in the KPBP3A manual. I think you will get a LOT of agreement that installing the KRX3 module is one of the most complex bits of assembly of the K3S. We've made many "tweaks" to the procedure in the attempt to make it easier, but it is still not simple. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of wa9fvp Sent: Saturday, April 15, 2017 1:27 PM To: elecraft at mailman.qth.net Subject: [Elecraft] Sub Receiver & KBPF3 I just installed the Sub receiver and the KBPF3A in my K3S. I have one complaint and one concern. First the activation of the KBPF3A is very vague. It's mentioned in the users manual on page 60 (the configuration menu) but there's nothing that says, while in (CONFIG:KBFP3) that you have to press [SUB] and then select "nor". I double checked the installation manual for the sub receiver and the KBFP3A but there was nothing about activating the General Coverage filters. My concern is; I consider myself as an experienced kit builder but for me, it was a bit difficult installing the Sub-Receiver. The TMP cables were in the way and sub-receiver box was a bit difficult getting the SUBIN and SUBOUT boards to align and mate properly. Someone who is new to kit building would have a more difficult time. The sub-receiver is working great and the one thing I like about it is; it's a clone of the main receiver with FM, AM, 2.8, 400 and 250Hz filters. I wonder how the sub-receiver would stack-up on Sherwood Engineering's test data.

A CME just grazed us and another high speed stream of wind is on the way for tomorrow. Ions are getting to the ionosphere but nothing like last spring. Spinning the knob gives me not much to nothing on the higher bands while lower down there are more stations. The week was filled with a variety of precipitation types. Only this morning there were flakes of snow, slushy streaks of snow, pellets of snow, and rain. Between the snow falls, the rain showers, and the gusty winds there were a few pauses. Let's me collect wood and not get soaked. Then came the sun. Not just for five minutes but for a number of hours. Maybe winter is losing its grip. I had not seen the sun for that long since October.

After running for a bit, the ATU seemed to stop working. Attempting to retune on 40m, it would stick at a 25.4:1 SWR. Tried switching down to 20m and it retuned right away to a 1.3:1. Applying external power to the unit, I tried tuning again on 40m (battery was reporting 10V if I recall correctly); It then tuned the end fed up, but only to a 1.7, which it will typically match to a 1.0:1, it would also get stuck at the 25.4:1 SWR on some of the attempted tunes. Trying another dipole I have (10m), and with external power, it will tune up 30m, 20, 10m to a good SWR (1.0 or 1.2 :1), but on 40m, it will either tune to ~1.7 - 3:1 (expected), or it falls back onto the 25.4:1. When the relays are running through the tuning procedure, I'm noticing that for about half the time the relays are clicking, it's showing a 25.4:1 SWR. What I mean by this is that it seems for all the possible tuning combinations/paths in the tuner used on 40m, there is a fault some where leading to the 25.4:1 SWR for many of the paths/combinations. Found this old mailing list post [1] which the resolution was to have it sent in for repair, which replaced Q2/Q7. I'm wondering if anyone has a suggestion on testing or this issue. I don't have a dummy load to test with at the moment, but have one on order. Should I suspect it is an issue with the ATU or more likely Q2/Q7? It would most likely be cheaper/faster to replace the ATU, but I'm guessing it's more likely that it will need to be sent in for repair, and the ATU is fine. Any insight is appreciated.

Pf1-Pf4 in the rev.2.75 works just great and makes my mobile operations so much easier! I have assigned Pf1 to VOX, Pf2 to XIT, Pf3 to BKLIGHT, Pf4 to DUAL RX ( that's more for fixed rather than mobile use). I have yet to discover the sense of having two ATU Data Sets. Theoretically it lets you to skip the tuning procedure each time you swap the known antennas. But practically what matters is how many buttons you need to push to get the antenna tuned. So, with two ATU sets you have to push at least 3 buttons ( go to menu, choose the set, go back to general display) in order to get the antenna right. But for ordinary tuning procedure you only need to push the ATU button once and the antenna ( any antenna) gets tuned in a second! :) . And last but not least, even the same antenna may need different tuning depending on the physical condition like snow, rain etc. Anyway, thanks for a quick reactions to the elecrafters community ideas!

Swapping the K3SYNA boards brought both rx and tx back to life. What puzzles me ist the fact that the SUB-RX also works fine. So both K3SYNA boards seem OK. Initially i assumed the Main K3SYNA is defective. Maybe something had gotten loose or lost contact the moment i checked the antenna match, dunno. One more thing: The moment i removed the temp cables from the K3SYNA boards i forgot their correct positions.

Sometimes (typically every other or every third time, but randomly), when pushing (and holding) the tune button with the power set to 11 watts or more, I get a high reflected power message on an antenna which is matched at low power. The power supply voltage reads about the normal 14V and the ammeter in the power supply is pinned at 25 A (or more) when this happens. An external SWR meter reads lots of reflected power. Everything unplugged from the rig except the power cable and the coax to the external SWR meter/antenna tuner/antenna. It's fine on a dummy load. I'd suspect a simple RF feedback problem, except that with 100 watts of CW everything is perfectly normal. The problem occurs only when using the tune button around the nominal tune-mode 20 watts, so the external SWR meter reading implies that the PA is probably oscillating at some frequency where the antenna is not matched. I haven't tried any other bands yet, but since there does seem to be RF feedback involved, I'm not sure they will tell me much of a diagnostic nature.

While the arc is flashed, the feed Z goes very low. And the SWR therefore goes very high. And it takes less energy to continue the arc than to start it. The key here is that the SWR changes when the trouble starts. An antenna is constantly subject to mechanical stress. One thing you can count on with any antenna you put up is that it will fail at some point and require maintenance. It's not if, it's when and how. 73, Guy K2AV On Sun, Apr 16, 2017 at 10:52 AM Steve Kavanagh via Elecraft < elecraft at mailman.qth.net> wrote: > This one cropped up just today, with no significant change in my home > station setup, using a K2/100 on 40m using a low inverted Vee. > > Sometimes (typically every other or every third time, but randomly), when > pushing (and holding) the tune button with the power set to 11 watts or > more, I get a high reflected power message on an antenna which is matched > at low power.

He was on 15m and I was on 20m. Our antennas were placed about 30-40 feet apart, as slopers with the radiating ends up 30+ feet in the air using Jack-kite poles. The plane of the antenna's slope were perpendicular to each other. We were both on 10w SSB. Every time one of us keyed up, the other person's KX2 would experience a nasty noise from the signal. Pre-amp was off, as was attenuator. My question is this: Would the use of some bandpass filters have helped us? This is a situation we are trying to resolve before operating QRP in a similar park for a QSO party. If more distance between the antennas would have helped, what is the proper way to determine the needed separation?

I plan on running the server on the computer connected to the K3S. I would like to do this with no additional interface other than the built in USB sound card. If I set up the server with Speakers USB Audio CODEC as the Tx Audio to Radio will this pass the audio from the client to the radio either via VOX or by me pressing the Transmit button on the client. I have set up the system as mentioned above and have the receive audio from the rig going to the client on my remote computer. I do not have a microphone headset for the remote computer yet and before I buy one I would like to make sure that the codec will pass the client audio to the radio while in SSB mode. I think I might have read where the CODEC does not work in SSB mode but only in one of the data modes.

Maybe. It depends on whether you were hearing the other radio itself, or intermod created by some nearby non-linear device that re-radiated it. Bandpass filters will take care of the other radio, but not the intermod. 30-40 ft is pretty close, even for 10W and KX2s. > This is a situation we are trying to resolve before operating QRP in a similar park for a QSO party. > > If more distance between the antennas would have helped, what is the proper way to determine the needed separation? If you're hearing the other radio, RF loss in the path between the two antennas can be computed using NEC. To do that, put both antennas in the model, put a Source at the feedpoint of one antenna, put a 50 ohm load at the feedpoint of the other antenna (but no source). Set NEC to compute for 10W (or whatever power you want to run). Then compute the pattern, and click on Load Data to see how much signal is induced at the other antenna. BUT -- another issue comes to mind. You say "resonant end-fed antennas." All antennas need some form of return conductor for antenna current. What form do your antennas take? What's the return for antenna current? Is it the coax? If so, is there a ferrite choke at some point so that current is confined to the intended length? How close are the rigs? And when you build that NEC model, be sure to include that coax and any other counterpoise. 73, Jim K9YC From k6dgw at foothill.net Sun Apr 16 14:08:26 2017 From: k6dgw at foothill.net (Fred Jensen) Date: Sun, 16 Apr 2017 11:08:26 -0700 Subject: [Elecraft] OT - operating QRP at same park In-Reply-To: References: Message-ID: At 30-40 ft separation on 15 and 20, your two antennas are probably within each other's near-field and each is thus "part" of the other. The coupling in the near-field can be very high. The general rules are: 1. Separate the antennas by as much as possible, preferably several wavelengths. A wavelength on 20 meters is ... well, ~20 meters [roughly 67 international feet]. 2. Orient/position the antennas such that one is in the other's null. For half-wave dipoles, that's off the end and FD experience suggests colinear with each other and well separated works best. Note however, if they are within each other's near-field, orientation may have little if any effect [see #1 above]. During the BPL bruhaha a number of years ago, I modeled my my non-resonant sloping-V and a couple of 12 KV distribution lines [which would have been the BPL carrier] together using NEC-2, similar to K9YC's suggestion, to see how badly I would disturb my neighbor's BPL I'net if he had it. The coupling coefficient on 40 meters and higher was pretty stable at around -30 to -35 dB. On 80 and 160, where the power line and antenna shared a near-field, the coupling was in the -10 to -15 dB range. As you describe them, and with perhaps 10 watts for easy math, the received power might be one or two tenths of a watt.

The radios were about 30 feet apart and the antennas maybe 40-50 feet apart. If the KX3's success was due to the roofing filters installed, could some sort of external filter added to the KX2 contribute to a solution?

Both are separate for 30-20 and 17-15 bands. So soem but probably not much attenuation from 20 to 15 and vice versa. The attenuation between 17 and 40 is likely much stronger. I assume that the front end in KX2 is same as in KX3. The bandpass filters in K3 also cover two bands but have extra caps switched in, probably for single band coverage. This would explain why K3's are not interfering much cross band.

I would suggest that the situation would be greatly different if the antennas were sloping dipoles resonant on each band, and even better if decoupling ferrites were used at the feed points of the dipoles.

To do that, put both antennas in the model, put a Source at the feedpoint of one antenna, put a 50 ohm load at the feedpoint of the other antenna (but no source). Set NEC to compute for 10W (or whatever power you want to run). Then compute the pattern, and click on Load Data to see how much signal is induced at the other antenna. > > BUT -- another issue comes to mind. You say "resonant end-fed antennas." All antennas need some form of return conductor for antenna current. What form do your antennas take? What's the return for antenna current? Is it the coax? If so, is there a ferrite choke at some point so that current is confined to the intended length? How close are the rigs? And when you build that NEC model, be sure to include that coax and any other counterpoise. > > 73, Jim K9YC > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to jackbrindle at me.com From detrick at merzhaus.org Sun Apr 16 16:22:28 2017 From: detrick at merzhaus.org (Detrick Merz) Date: Sun, 16 Apr 2017 16:22:28 -0400 Subject: [Elecraft] OT - operating QRP at same park In-Reply-To: References: Message-ID: I was there with K4VD for this.

In a recent WWFF outing we had a KX3 and an FT-817 set up. We separated the antennas best we could but really didn't pay a lot of attention to it. I believe the KX3 was on 40 and the 817 on 20 meters. The KX3 never heard the 817 but the 817 (no roofing filters I think) washed out when the KX3 was keyed. The radios were about 30 feet apart and the antennas maybe 40-50 feet apart. If the KX3's success was due to the roofing filters installed, could some sort of external filter added to the KX2 contribute to a solution? Is the KX3 meant to play well with others while the KX2 is intended more for a solo trip? I understand W4RT has optional roofing filters for the FT-817. I wonder if he or someone might come out with a good option for the KX2.

You might also look for bad solder joints between the PA transistors and the antenna. And, just in case, check to make sure there are no bad (arcing) connectors in the antenna path.

The power supply voltage reads about the normal 14V and the ammeter in the power supply is pinned at 25 A (or more) when this happens. An external SWR meter reads lots of reflected power.

The problem occurs only when using the tune button around the nominal tune-mode 20 watts, so the external SWR meter reading implies that the PA is probably oscillating at some frequency where the antenna is not matched. I haven't tried any other bands yet, but since there does seem to be RF feedback involved, I'm not sure they will tell me much of a diagnostic nature. > > Any ideas as to what might be happening and how to stop it? > > 73, > Steve VE3SMA > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to jackbrindle at me.com From ns9i at bayland.net Sun Apr 16 16:32:06 2017 From: ns9i at bayland.net (dgb) Date: Sun, 16 Apr 2017 15:32:06 -0500 Subject: [Elecraft] FS KXV3-2 REV A In-Reply-To: <1492373423463-7629379.post@n2.nabble.com> References: <1492373423463-7629379.post@n2.nabble.com> Message-ID: I updated my K3 to with the KXV3B thus have a KXV3-2 REV A (2007).

A buffer amp following will solve that . My reply was merely to indicate tapping the 1st IF at W3 is a good decision. I run both main Rx IF and sub Rx IF to LP-Pan that have the optional IF amps installed (now std in the LP-Pan 2). Both appear to work fine bringing out the 1st IF to my LP-Pan which in turn provide IQ baseband input to a four port soundcard for diversity reception on 2m-eme (a special application using digital modes). I did determine that feeding the 1st IF to the 2nd IF of the K3 loaded the panoramic display at frequency zero, so I select a xtal location that is unfilled to effectively disconnect the 2nd IF. But normal use of the K3 using the entire receivers works fine. I do not detect any loading of the 1st IF by either LP-Pan. Now probably one should use a 0.01uF cap instead of 0.001uF for 8.215 MHz. That will provide a little more RF coupling. One other item I did omit is the use of a ferrite on the RG-174 for isolating the shield for any noise introduction to the IF. 73, Ed - KL7UW From: wa9fvp To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Sub Receiver I.F.

The 2.7 kHz 5-pole filter is not as flat as the 2.8 kHz 7-pole filter, which I noticed on RTTY. I subsequently switched to 7-pole filters (but not in the Sub-RX). A JT65 signal is about 220 Hz wide, so when you get near the top of the audio bandpass, you also run into the slope of that filter. As with all other data modes transmitted by audio, 4-5 bars flashing is optimum. There's another trick that the latest WSJT-X plays to minimize audio harmonics that result from overdriving in the audio chain. If you allow WSJT-X to do so, they will automatically put you in split mode, with an offset that puts the second harmonic outside the passband of the TX filter. My recommendations for setting audio levels is here. it follows the discussion of USB interfaces. http://k9yc.com/USB_Interfaces.pdf The reason I recommend setting computer sound cards 6-10 dB below audio clip is that their percent distortion often rises by 10 dB in that last 6 dB of output level. On a vintage Thinkpad, I measured -30 dB second harmonic relative to fundamental just below clip and and -40 dB below fundamental with the output reduced by 6 dB. One update to my "rule of thumb" about whether you need a better interface is that, thanks to decoding improvements in the latest version of WSJT-X, you should occasionally see good decodes in the range of -26 to -28 for JT65. And a caution -- while second pass decoding often finds a second station on nearly the same frequency as one decoded on the first pass, roughly 5% of the time a second pass decode may be bogus. 73, Jim K9YC On Sun,4/16/2017 2:29 PM, Dave Hachadorian wrote: > Transmitting on JT-65, I see a lot of variation in ALC and power as the various tones change.

Sound card output is about 50%, and Line In level is at 12. Is this variation normal, or am I doing something wrong, and where should I set the ALC?

He told Ben to give up study of physics unless it was a true passion because that was the only way to succeed in anything. Ben said he realized this was the only advice he needed to change majors and later succeed in his new field. His main regret in doing so was losing Feynman as adviser. Not exactly related, another retired coworker as a young researcher used to take a train up to Princeton each month to lunch with Einstein.

At one point, the chalk hit the blackboard, he wrote out an equation [or something like that] and then said, "This is obvious, of course." He paused, turned and left the room, leaving everyone wondering if that was all. A couple of minutes later, he was said to return and continue the lecture with, "Yes, it is definitely obvious."

The *only time* power output is not as expected is if I am not using split mode and trying to transmit with audio tones below 300 Hz or above 2500 Hz (outside the DSP bandwidth). 73, ...

Refine that level with slight adjustments to the LINE in gain. You can use TX TEST while making those adjustments which will not transmit any RF. Adjust the desired power output with the power knob. If you do not achieve the required number of ALC bars, the K3 will "power hunt" causing significant fluctuations in the output power. There seems to be a greater number of questions about this "problem" for users of "JT" software than for other soundcard data modes. I don't know why because the "JT" software should be no different than any other soundcard data mode. Perhaps the user is trying to follow the recommendations in the JT mode instructions (I have not looked at them), but typically data mode instructions are for non-Elecraft tranceivers and say that the user should set the power to maximum and use the soundcard audio to adjust the power level. That does not work with Elecraft gear which controls power differently than other amateur transceivers. For Elecraft transceivers, adjust the audio level as specified and adjust the desired power with the power knob. I cannot stress this fact enough. 73, Don W3FPR On 4/16/2017 9:19 PM, Brian Hunt wrote: > Don't see a problem with making minor adjustments of the Line In gain during the first transmission.

I felt like some of the joy went out of ham radio when he passed in 1997. Interestingly enough as a college DJ at WMUA-FM, at UMASS Amherst, MA in the late 1970's, and by total happenstance at a concert I met his son Dave (Douglas David) N8HLE, who was a writer and an awesome DJ at WWUH-FM, at the University of Hartford, CT. I introduced myself to him as a fellow DJ, and the second thing I said was that I was a ham and his Dad was a hero of mine, and he said "Mine too!" Dave was one of the nicest guys you could imagine, and went out of his way to call me years later when I was doing DJ shifts on WXYC - UNC Chapel Hill, NC and compliment the show and talk music...I stayed in touch with him on and off until his own untimely death in 2011. Doug DeMaw was one of the greats in ham radio, and judging by his son, a great father as well, W1FB indeed. :'( Howie - WA4PSC From donwilh at embarqmail.com Sun Apr 16 22:45:58 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 16 Apr 2017 22:45:58 -0400 Subject: [Elecraft] Heathkit Tool.

At our first Field Day, we had the usual problems as described by the original poster. Especially so because we were both running 500 watts. On our second and all subsequent operations we operated with one station on a vertical and the other with a horizontal antenna. That helped a lot. On our third and subsequent mountain top FD expeditions we put a receive-only antenna 800 feet away and fed the sigs back to the operating tent with a big roll of RG-6 quad shield. Problem solved. There are a few mechanisms available to aid in ?separation?. Get the antennas physically as far apart as possible. Try cross polarization. Operate on bands as far apart as possible. Band pass filters. Stubs. Some antenna tuners are configured as low pass; some are configured as high pass. Single band resonant antennas are band pass filters (watch out for odd harmonics). 73, Doug, W7KF http://www.w7kf.com > On Apr 17, 2017, at 9:14 AM, Bert via Elecraft wrote: > > Jack, W6FB, made a good point about resonant antennas.

I set the LINE IN gain to 30 (midrange). The speaker output is set to 90%, but there is an amplitude slider in WSJT-X, and I adjusted that to 5 bars of ALC in WSJT Tune mode (constant 1100 Hz tone in this case). The K3 is definitely in DATA A mode. Then I called CQ, and the ALC meter and power output were all over the place from 0 - 5 on ALC, and 10 Watts to 70 Watts on power output. On an external analog wattmeter, I could see the power ramping up on some of the longer duration tones. So then I took an oscilloscope and measured the audio voltage coming out of the sound card, and found that each tone has a different voltage level coming out of the sound card! The audio level varies all over the place as the CQ goes on. JT-65 is supposed to be constant amplitude tones of 65 different frequencies, so something is not working right, either in the WSJT-X program or in my computer. I will look into that some more. It is not a K3 problem. I am using WSJT-X v. 1.7.0 r7405. The sound card is an old Soundblaster Live that works just fine for transmitting WAV and live microphone on SSB. Anyway, I am making QSO?s, some of them with signal strength as low as ?25 dB. I don?t think I am long for this mode anyway. Life is too short for 1 Baud communication.

Refine that level with slight adjustments to the LINE in gain. You can use TX TEST while making those adjustments which will not transmit any RF. Adjust the desired power output with the power knob. If you do not achieve the required number of ALC bars, the K3 will "power hunt" causing significant fluctuations in the output power. There seems to be a greater number of questions about this "problem" for users of "JT" software than for other soundcard data modes. I don't know why because the "JT" software should be no different than any other soundcard data mode. Perhaps the user is trying to follow the recommendations in the JT mode instructions (I have not looked at them), but typically data mode instructions are for non-Elecraft tranceivers and say that the user should set the power to maximum and use the soundcard audio to adjust the power level. That does not work with Elecraft gear which controls power differently than other amateur transceivers. For Elecraft transceivers, adjust the audio level as specified and adjust the desired power with the power knob. I cannot stress this fact enough. 73, Don W3FPR On 4/16/2017 9:19 PM, Brian Hunt wrote: > Don't see a problem with making minor adjustments of the Line In gain during the first transmission. When I adjust the level using the WSJT TUNE button I usually see the wild fluctuations mentioned. A small "tweak" to the gain will set right. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to k6ll.dave at gmail.com From donwilh at embarqmail.com Mon Apr 17 14:20:17 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Mon, 17 Apr 2017 14:20:17 -0400 Subject: [Elecraft] KX3 tuner getting stuck at 25.4:1 SWR In-Reply-To: <18889ED6-34C4-4A02-BFFA-666CB631B797@gmail.com> References: <18889ED6-34C4-4A02-BFFA-666CB631B797@gmail.com> Message-ID: Nate, Since the problem is intermittent, I would not suspect a problem with an active component.

We built a house next door in 2009, and two ground rods separated by 6 feet was required. So sometime between those two dates the NEC requirements changed. None-the-less, I have a perimeter wire around the house with a driven ground rod at each corner. Since I have 45 degree corners on one side, and several other 90 degree offsets that means I have 9 ground rods plus the one at the utility entry, so I think I am "covered". 73, Don W3FPR On 4/17/2017 5:00 PM, ab2tc wrote: > Hi, > > This is totally off topic; I apologize. > > I just received the new ARRL publication "grounding and bonding for the > radio amateur".

In the latter 60's, the NEC permitted it unless a buried water pipe was available, and sometime in the late 70's made them a requirement. The NEC now calls them Concrete Encased Electrodes. The NEC currently requires that CEE's be rebar in the concrete [usually the foundation] and can be difficult to find since very little if anything will be externally visible. Our home is 4 years old and I can't see the actual ground connection. I can see the ground conductor headed downward from the service entrance. I presume it connects to a CEE. [:-) As to your power pole: If it has a distribution transformer, it will very likely have lightning arrestors on the primary with a ground conductor and electrode. If it doesn't have a transformer, it's only purpose is to hold up the conductors on insulators. None of this drivel applies to RF. 73, Fred ("Skip") K6DGW Sparks NV USA Washoe County DM09dn On 4/17/2017 2:00 PM, ab2tc wrote: > Hi, > > This is totally off topic; I apologize. > > I just received the new ARRL publication "grounding and bonding for the > radio amateur".

Personally, I remove my equipment from the antenna system remotely during bad weather and generally when not operating, via a remote antenna switch, which I forgot to mention. When storms are eminent, I disconnect remotely and allow the discharge devices to handle static issues without the rigs connected to the antennas. No losses to date....

Mode is apparently set by selecting FSK-D, PSK-D or CW from the K3. Correct? 2. It says to keep text decode off on the K3. Does the Threshold adjustment have any effect? I've never used text decode. Is Auto good enough? 3. It looks like the easiest way to set everything up is Ctrl-Alt-S on the keyboard and adjust from there. Any reason to get into the 'regular' menus through the Menu button?

Direct lighting strikes on houses are less common than power line surges. So house grounds are designed for surges, which can be large. A direct strike on a stucco house is going to vaporize the wire mesh and blow the stucco off in several places. Ground rods won?t help that much. A tower is much more likely to get a direct strike. The grounding system on a tower is designed to survive a feeder strike and reduce the destruction (risk) of a direct strike. Better to melt the coax than burn down the transmitter shack. When I was in high school in Indianapolis, my next door neighbor was a ham with a tower. He had worked on lighting arrestors at GE. He explained that a lighting pulse had so much high-frequency energy that it more followed than conducted along a ground strap. It jumps from the strap to the building and back about every two feet. Lightning systems are a hint, not a directive. Nobody tells lightning what to do. I like what I do, but working on lighting arrestors? That would be COOL. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Apr 17, 2017, at 4:16 PM, Wes Stewart wrote: > > Clearly, you have something in mind different from me. > > https://www.tessco.com/products/displayProductInfo.do?sku=12952 > > Tell me how you avoid the exploding concrete myth using something like this? > > Or with a bolted base plate: > > https://www.cableandwireshop.com/rohn-45g-tower-concrete-base-plate-r-bpc45g.html > > Read the last sentence. > > > On 4/17/2017 3:25 PM, Bill Johnson wrote: >> No, unless adequate steps are taken to assure a large ground grid is made.

I reviewed the webpage on the Heil Sound website here:?https://heilsound.com/heil-amateur-radio/support/dsp-settings/all-things-elecraft/? Unfortunately, the page refers to the mic with regard to the front panel setting, but does not specifically refer to the mic model with respect to the mic gain and mic bias settings. I sent an email to Heil Sound suggesting that the missing detail be added for this particular mic. But thought I'd ask here, in case anyone knew the answer. I deduced that the setting should be Front Panel, Low, No Bias, but am not 100% sure about that! Here's the strange part about this story. I did have a QSO with a station in North Dakota after setting up the rig, so we knew all was working. We shut off the rig and I left for home. Later in the evening, my godfather turned the K3 on and tried to transmit, but noticed that he wasn't getting any moving bars with the transmit audio. I walked him through putting the K3 into test mode, turning down the mic gain, and then turning up the mic gain while he was transmitting to find the optimum level, but we couldn't get the meter to show any response to the audio. I did the same procedure on my own K3 to make sure I was talking him through the right steps and it worked fine on mine. He did try a Heil headset with the same results. I plan to try and get up to visit again this weekend and bring a hand mic with me to try and make sure that it is definitely the K3 and not the mic. So unless I'm missing something obvious, it seems like there is an issue with the K3 itself. Unfortunately, Elecraft support couldn't go beyond the same tests that I did last night. Does anyone have any suggestions short of shipping to, or dropping off the rig, at Elecraft for a thorough test??

For instance, I am using spacers made of a material called "nylon 6,6 30% glass fiber-reinforced" which happens to have a relative permittivity of 3.9. This has the effect of increasing the effective permittivity between the wires from 1.00059 to 1.08656. Another way of saying this is that the velocity factor goes from 1 (for pure air) to 0.959, or about 96% with the spacers. The effect of this is to make the characteristic impedance of the line drop from around 480 to around 460 ohms. ( See http://www.emclab.cei.uec.ac.jp/xiao/Wire/index.html ) This obsessive exercise on my part illustrates that spacers don't make a whole lot of difference, but they do make a difference. You may want to include their effect or not.

I know guys that are doing all the wrong things with their practices. They can't be persuaded otherwise. Yet, the odds have favored them for years. That reinforces their thinking that they are right and logic is wrong. But I have seen what has happened to others. Lightning strikes are one hazard. Static energy build up on antenna systems is another. Both can destroy. And, then there is the lightning type potential coming in on the AC power line to consider.

You tell me how many of them have exploded during lightning strikes, and how that justifies the admonition to "never encase a ground rod in a tower base". I once did an extensive internet search trying to find documented examples of concrete structures that had exploded from the inside out due to internal grounded conductors. I couldn't find a single one. Maybe you can find one, and if so I'd like to see the link. I did find several instances of damage to concrete structures from lightning hits, but all of them had external damage from simple lightning strikes. Most other damage was attributed to the fact that there wasn't any grounding at all ... i.e., an ungrounded structure on top of a concrete base. From a theoretical point of view, I could picture a discharge causing more damage from insufficient metal in the concrete rather than too much. Spread the current ... minimize the heat buildup. If you want to argue that a single ground rod in a concrete base is a poor idea, OK ... I can buy that. But these other blanket statements are garbage science.

In the early 1970?s, the power company I worked for was testing out some hollow reinforced concrete poles. There was considerable concern by the line workers that the poles might be more dangerous to work on than wooden poles, in the event of an accident. To check this, we installed one of the poles in a sub station, and wrapped a 26KV 1200 amp feeder conductor around the pole. When the station breaker was closed, the pole exploded dramatically, with a large fireball. The results might have something to do with moisture content in the concrete. The results convinced us to only use the poles on transmission lines that wouldn?t be worked hot, like we did with distribution lines.

All used to be fine, but over the weekend I noticed it now only gives ~6W maximum on CW despite a good SWR indication. I have reproduced this into a dummy load (1.1:1 SWR) and checked DC input voltage (11.2V key down, external 3S LiPo). Additionally, if I engage the ATU, it no longer seems able to find a good match, even into a dummy load. Bypassing the ATU results in an indicated 1.1:1 SWR, and removing the ATU module does not fix the low output power problem. If I run the manual TX power calibration (set power to 6W and hold TUNE), the VFO B display reaches about 5.4W then stays there. Tapping TX to stop the procedure results in ERR TXG being shown. Doing the same at 4W results in maximum output power of about 3.2W, from memory, and a similar ERR TXG error. This is true on all HF bands. Any thoughts on where to look?

No problems happened, but maybe I just got lucky. Nobody had ever said anything to me to the contrary. For radio grounding to earth, I use 1/2 inch copper pipe 10 foot length and get it in the ground hydrolically with a fitting that lets me put the garden hose to the end and shoot water from the other end to make the hole. Works really well. And I have wondered whether to connect another 10 feet and go deeper. I have 5 of those connected together in common.

I walked him through putting the K3 into test mode, turning down the mic gain, and then turning up the mic gain while he was transmitting to find the optimum level, but we couldn't get the meter to show any response to the audio. I did the same procedure on my own K3 to make sure I was talking him through the right steps and it worked fine on mine. He did try a Heil headset with the same results.

For instance, I am using spacers made of a material called "nylon 6,6 30% glass fiber-reinforced" which happens to have a relative permittivity of 3.9. This has the effect of increasing the effective permittivity between the wires from 1.00059 to 1.08656. Another way of saying this is that the velocity factor goes from 1 (for pure air) to 0.959, or about 96% with the spacers.

The P3/SVGA does not actually decode any RF. All that is done inside the radio and you must choose between any of built-in modes, such as FSK-D, PSK-D or CW. 2) The manual instructs you to turn off text display ONLY if you're going to use the K3 or P3 Utility's data terminal mode. Text decode on the radio will need to be turned on (see #1 above). 3) The P3/SVGA setup screen which is accessed via Ctrl-Alt-S on an attached keyboard is used to set a variety of settings pertaining to the keyboard aspect of the system. For example, setting the foreground and background colors for the text window on the SVGA screen. Also setting up the text transmit mode, i.e. send on Enter key press, space bar key press, etc. This controls when the text is sent to the radio to be transmitted, for example, when the Enter key is pressed, or the space bar etc. If you need additional help or have any questions, please email me directly.

One large modifier to the end result is the number of spacers per unit of length. Then there is the issue that the relative permittivity in between spacers reverts to air away from the spacer. Then there is the area on either side of a spacer where the effective permittivity blends from that of the spacer to that of air. Then there is the loss based on number of spacers and loss tangent of the spacer material modifying the lesser air loss. Beyond that there is this peculiar ham inclination to use indoor insulated electrical wire (THHN - rated dry indoors inside conduit only, 600 volts at 60 Hz) for QRO outdoor RF purposes. E.g. https://www.73cnc.com/product_p/ls31.htm Figure the wildly variant composition of PVC insulation at manufacture followed by years of deteriorating UV outdoors. In the end it is far easier to construct a feedline with a scientific guess to obtain a target Z zero and then measure and adjust design to hit it on the head and/or reduce its loss. In practice there is little difference between 400 and 450 that is not soaked up by all the tuner or circuitry finaglement we must engage in to convert a wild range of Z to the narrow, narrow range actually tolerated by our transistor finals. Wireman for years has been selling various window lines we all euphemistically call "450 ohm" which in fact vary between 360 and 440 ohm Z zero. The reason for the variance is the spacing on all those lines is identical regardless of the variation in wire diameter. The constant wire diameter reduces the manufacturing setup and run costs passed on to a cheep penny pinching ham population. [I include myself as afflicted by this penny-pinching malaise. I just try to keep this nearly irresistible inclination from dragging me into stupidity, as it has already done on some number of occasions.] 73, Guy K2AV On Tue, Apr 18, 2017 at 11:00 AM, k3hx at juno.com wrote: > > > Message: 4 > Date: Tue, 18 Apr 2017 03:31:59 +0000 (UTC) > From: Al Lorona > To: "elecraft at mailman.qth.net" > Subject: Re: [Elecraft] OT; Feedline question > Message-ID: <852881305.2998918.1492486319834 at mail.yahoo.com> > Content-Type: text/plain; charset=UTF-8 > > If instead of using the relative permittivity of air, 1.00059, for > calculations of open-wire line, you use the effective permittivity > including any spacers used to homebrew the line, this value will increase > slightly. > > > > For instance, I am using spacers made of a material called "nylon 6,6 30% > glass fiber-reinforced" which happens to have a relative permittivity of > 3.9.

Below UHF, loss in transmission line is virtually all due to copper losses unless the dielectric material is wet or is otherwise made conductive. Quite a few years ago, N6WS did some excellent work showing that losses in window line are greatly increased when it is wet. His work was published in QST and later included in Antenna Compendium #6. It should be required reading for anyone considering window line. He measured four types of window line and some open wire line he built himself. Putting some numbers to it, Wes's measurements showed loss at 50 MHz increased from about 0.4 dB/100 ft to more almost 6 dB/100 ft when it was wet. The open wire line showed no increased loss when wet. 73, Jim K9YC From k2av.guy at gmail.com Tue Apr 18 13:41:50 2017 From: k2av.guy at gmail.com (Guy Olinger K2AV) Date: Tue, 18 Apr 2017 13:41:50 -0400 Subject: [Elecraft] OT: Ground rods and concrete In-Reply-To: <191B5755E4654B65951378A9EF28A8F1@DOUG8PC> References: <191B5755E4654B65951378A9EF28A8F1@DOUG8PC> Message-ID: Part of the mental imaging problem here is that our brains, in their internal emotional response to orders of magnitude, simply cannot scale the destructive power in lightning. Lightning is quite capable of melting the leads to six properly done ground rods, AND at the same time blowing up a perfectly done to code concrete base with reinforcing rods. It just needs to be a big enough strike. I would guess (zero proof, just a nagging inclination) that the odds of this are considerably reduced by the presence of decently tall trees in the immediate vicinity (another loooong discussion). Anyone who has seen a lightning strike turn three or four cubic yards of ground dirt into glass in milliseconds, or seen a huge strike on a lake surface boil water within a 10 foot radius has a good gut based lightning strike power scaling device.

And I strongly agree with AB7E's excellent post. The cited article does NOT say that "The Broadcast industry doesn?t seem to put their faith in Uber grounding." It DOES say that a Ufer ground done improperly can be a problem structurally. Notice also that the author "is national program manager for Copper Development Association Inc." I see nothing in the way of engineering credentials. The author quotes extensive advice from "a power quality expert, Martin Conroy," again with no credentials given. That said, Conroy's advice is pretty good, and is mostly in agreement with good engineering practice. He did not say that the Ufer ground was a bad idea, but he did recommend supplementing it with deep rods around the tower, spaced radially out from the tower, and a buried ground ring, all robustly bonded together and to the tower. If you read the new ARRL book on Grounding and Bonding (by N0AX), you will see a recommendation for a Ufer ground within the tower base, bonded to the tower, and to multiple ground rods around the tower base, spaced at least a rod length from the tower and from each other. If the tower is close to the building, it calls for bonding between the tower ground system and the building ground. If the tower is more than 60-100 ft from the building, bonding is NOT recommended (or useful) because that bonding conductor (and the coax shield) have too much inductance to be a low impedance at RF. I was one of several engineers who Ward consulted for peer review, and much of the book parallels my tutorial on Grounding and Bonding for ham radio. 73, Jim K9YC On Tue,4/18/2017 10:35 AM, Wes Stewart wrote: > I don't know whether I would call that "extensive" damage but whatever... > > I have my own photos of me standing next to this anchor, but since I > can't send attachments, here is a link: > https://en.wikipedia.org/wiki/KVLY-TV_mast#/media/File:KVLYPylon.jpeg > > I didn't see any extra grounding conductors.

Where hung on the level in a misting rain, I have seen a droplet per centimeter hanging on THHN insulation. Along with a rather large variation in Z as seen in the shack. Just one more reason to keep to bare wire. Bare wire sloughs rain. I remember 300 ohm TV open wire line from bare #18 copperweld with molded spacers every three inches. The 300 ohm ladder line if run near a furnace or fireplace flue would "go bad" on TV channel 2 as well as the UHF channels. There was also this phenomenon called acid rain which could severely modify electrical behavior, including etching the copper conductors. With the PE formed 300 ohm line, the reduction in signal strength could be blamed on "the rain", which was true in one sense. But since it got better when it dried up, the PE supported balanced line would never get the blame. 73, Guy K2AV On Tue, Apr 18, 2017 at 1:37 PM, Jim Brown wrote: > On Tue,4/18/2017 10:10 AM, Guy Olinger K2AV wrote: > >> Then there is the loss based on number of spacers and loss tangent of the >> spacer material modifying the lesser air loss. >> > > Below UHF, loss in transmission line is virtually all due to copper losses > unless the dielectric material is wet or is otherwise made conductive. > > Quite a few years ago, N6WS did some excellent work showing that losses in > window line are greatly increased when it is wet.

Much the same as putting a voltage across a speaker. It *could* damage the element is the element wire is not large enough to handle the current, but with the mic element not in its neutral position, the mic may sound funny. 73, Don W3FPR On 4/18/2017 1:59 PM, john at kk9a.com wrote: > If you use an electret with no bias you have no audio.

That's what Wes built to compare with the window line. Most practical implementations of open wire line use much wider spacing. The increased loss that Wes measured was due to water on the un-windowed parts of the window line -- in other words, a significant fraction of the dielectric between the conductors was water. That would not be true of widely spaced wire, insulated or not. 73, Jim From kwidelitz at gmail.com Tue Apr 18 15:17:49 2017 From: kwidelitz at gmail.com (Ken Widelitz) Date: Tue, 18 Apr 2017 12:17:49 -0700 Subject: [Elecraft] Feedline Question In-Reply-To: References: <20170418.174021.7364.5@webmail05.dca.untd.com> Message-ID: Ken Widelitz On Apr 18, 2017 1:53 PM, "Guy Olinger K2AV" wrote: > Guy, K2AV wrote: > > > The constant wire diameter reduces the manufacturing setup and run costs > > passed on to a cheep penny pinching ham population. > > > Please excuse, that should be "The constant wire SPACING reduces the > manufacturing setup and run costs. > > 73, Guy K2AV > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to widelitz at gte.net > From groups at planet3.freeuk.co.uk Tue Apr 18 15:33:53 2017 From: groups at planet3.freeuk.co.uk (Brian D) Date: Tue, 18 Apr 2017 20:33:53 +0100 Subject: [Elecraft] OT: Feedline Question In-Reply-To: References: <20170418.150033.30515.0@webmail02.dca.untd.com> Message-ID: What difference does oxidisation make on bare wire, ot tinning??

However if you have something like my situation things change rapidly. I have three towers the tallest is 175 feet to the top antenna. Trees are all at 75 feet or less. I am the neighborhood lightning rod. I installed this tower in late 1988 and in early 1989 we sustained a major hit. It blew up every radio computer the microwave the frig the TV sets. lots of coax and many other things made from metal. My station is in northern Indiana so we do get some nice thunderstorms. Not as bad as Florida but bad enough. My Assigned Risk insurance company said you have 30 days to either get that stuff all on the ground or install a "Commercial Grade" Grounding system. For the How to do it please read this 96 page PDF from Polyphaser. Polyphaser Grounding Guide After discussion with a couple of the Polyphaser Engineers who were also HAMS I purchsed all the goodies and we set about to create the ground system. It includes Whole House protection from Any wire that comes or goes from the house. This tower gets at least a dozen major hits per year. Since 1989 when the system was installed I have had Almost ZERO damage. The ONLY thing damaged was about 5 years ago the Whole House Protector on the Main Breaker box gave up its little life to save everything else in the house. I replaced it with a new one and all has been excellent prior to and since that time. The suggested Polyphaser Tower Grounding system looks a lot like that of the QST article from 2002 previously posted by one of our other posters. Radials 8 of them coming out from the tower. Polyphaser said they needed to be 1/3rd the length of the top antenna with 8 foot ground rods each 16 feet along the radial. And of course one of the radials goes to the house where the Single Ground Window... big aluminum plate with many protectors and two ground rods to hold it in place is located. And the Perimeter ground progresses around the house from that location. In my case since I have three towers in a triangle shape they said single run from tower to tower with again 8 foot ground rod each 16 feet along the way. Then rather than the 8 Radials from the single tower there are two starting outward from each of the other 2 shorter towers. #2 tower 130 foot and #3 88 foot tall. On those towers are about 20 yagi antennas 5 rotors and many many antenna switching boxes. Mostly Ameritron RCS-8V many modified as phase controllers for stack yagis. The back yard has 100 8 foot long ground rods connect by 1200 feet or 3/8" ID copper tubing. Silver Soldered to the Ground Rods. So read and heed the PDF from Polyphaser. It works!! 73 John k9uwa John Goller, K9UWA & Jean Goller, N9PXF Antique Radio Restorations k9uwa at arrl.net Visit our Web Site at: http://www.JohnJeanAntiqueRadio.com 4836 Ranch Road Leo, IN 46765 USA 1-260-637-6426 From wes_n7ws at triconet.org Tue Apr 18 15:57:51 2017 From: wes_n7ws at triconet.org (Wes Stewart) Date: Tue, 18 Apr 2017 12:57:51 -0700 Subject: [Elecraft] OT: Feedline Question In-Reply-To: References: <20170418.150033.30515.0@webmail02.dca.untd.com> Message-ID: <5851e728-b60c-0fae-8b06-0b3dc0491732@triconet.org> I'm cursed.

However: One of my clients operates a large 90 tower (all self-supported) microwave system here in Florida. Florida is often regarded as the lightning capital of the world. I have helped my client with repairing damaged (cracked) tower foundations. Approximately $1 Million have been spent over the last five years repairing concrete foundations that have embedded Ufer rods in addition to an extensive external grounding system comprised of radials and soil driven rods. No repairs have been needed to any of the tower foundations that do not have Ufer embedded rods. I have noticed that the damaged foundations cracks seem to appear after 15 years of service. This could be evidence of long term repetitive internal stresses - perhaps stresses resulting from steam expansion of the concrete's internal moisture due to repetitive high energy lightning pulses to the Ufer rod.

I worked in two-way communications for 30 years and recall all towers having external copper lines from the top to ground rods external to the concrete base. Most of the hardlines were equipped with grounding kits tied to that ground rod. Also, my house has no concrete slab (4-1/2 foot high crawl space with concrete block foundation walls interior of the crawl space is lined with HD plastic vapor barrier with bare ground floor under the plastic). Attached garage is on concrete slab. My 240vac service is buried from transformer box at property edge with buried utilities for about 1/4 mile where utilities run on wooden poles. There is a copper ground rod below my power meter box with what appears to be No. 10 solid copper ground wire. Service wiring is aluminum. Telephone service box is adjacent to power meter and ties its ground to the same ground rod. My ham shack is the third bedroom on opposite side of the house where I installed a ten-foot copper ground rod. I have a tower at end of house (about 40-feet from the ham radio entrance) and another tower 45-feet from the other end of the house. I run 120-foot 1-5/8 inch hardline from that tower to the ham radio entrance and ground the shield at both ends with a copper ground rod. The ground rod at the tower is tied to ground radials (on ground surface) for my inverted-L. To tie the radio ground rod to electric service ground rod would require about 100-foot run around edge of the house. However, I did run 45-foot of 240vac via the crawl space to the ham shack with 4-conductor wire which has No. 10 copper safety wire tied to ground at load center and at 60A breaker box in the shack, so all shack grounds including the shack ground rod are tied back via that cable. Main ground tie from 60A box to shack external ground rod is via No. 8 (includes grounding of 4.2kV PS to earth ground). Neither tower is bonded to a ground rod, so I have no lightning protection, though LMR-600 line on the tower ties the top antenna structure to the ground where the 7-16 DIN coax connection is made with the 1-5/8 line. That may offer some static drain but not lightning rated. Fortunately the maritime climate does not produce lightning wx. I have heard thunder maybe three times and seen a couple lightning flashes over the 25 years living in this area. Not saying it can't happen but the risk seems minuscule. BTW no lightening crash noise on 80m in summer (except that propagated by ionosphere from somewhere hundreds or thousands miles away). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From robert at syxis.co.uk Tue Apr 18 17:06:37 2017 From: robert at syxis.co.uk (M0VFC) Date: Tue, 18 Apr 2017 14:06:37 -0700 (MST) Subject: [Elecraft] Low power out, ERR TXG when trying to calibrate power In-Reply-To: References: <1492509330539-7629471.post@n2.nabble.com> Message-ID: Just to update on this thread: repeating the calibration on 10MHz with 13.8V applied does get to 4/6W indicated on the VFO B display, but on tapping XMIT, still gives ERR TXG (D=228 or thereabouts on the main bit of the display).

The term "exploding" was probably not correct. As several others have phrased it, an instant expansion of steam is more correct. Concrete is never totally "dry" in the context of this conversation. I witnessed lightening blowing apart the two tower bases I spoke of in person, directly, and in real-time. It happened in the mid-sixties at the St. Petersburg, FL Coast Guard base. As someone else has mentioned; the Tampa Bay region has the highest incidence of lightening in the Western Hemisphere. To the one of you who accused my of lying ... I was there ... you weren't. At the time I was an ET aboard the USC&GS (Now NOAA) Oceanographic Survey ship Hydrographer/WTEI and we were in the area deliberately attracting lightening with balloon-hoisted cables. I -do- know something about the infinite uncertainty of lightning. I'm a retired electric power company two-way radio tech and have probably dealt with more types of towers than most of you. Large electric transmission line towers are almost always set on four concrete piers, and are grounded with (usually) copper straps cad-welded to each tower leg and connected to ground rods a bit away from the cement. Each of us can search long enough to find "facts" that support our various positons, especially on today's Internet. Here in the mountains of the West ... as well other regions ... finding and maintaining a "good" ground at a radio site atop a mountain can be a "challenge". It's almost never done with ground rods. My power company employer has several hundred mountain-top microwave and/or radio sites. Been there, done that, as they say. One responder spoke of fitting a copper pipe with a garden hose fitting and "flushing" it into the ground. That works very well, and is how some of my 14 grounds are installed. It helps if the downward end is partly flattened, BTW. A much bigger problem overall than lightening is water collecting in tower legs, especially in climates where it can rust (undetected) from the inside and / or freeze and split one or more legs. There's an accepted way to avoid this. 73! Ken Kopp - K0PP On Apr 18, 2017 at 4:30 PM, wrote: > some 40 years ago, maybe longer I put up a 50' rohn 25G tower.

His recommendation, especially for his on premise cell phone towers, was to have as much metallic in the ground to detract large lightening hits to bypass radios and go to ground. K9KGM ( google his stuff) was his call and he not only believed but lived through major lightening hits to his towers, and counselled any of those he consulting with. You need adequate metal in the ground to dissipate the effects of a lightning strike. This doesn't guarantee against damage but certainly will help avoid the effect of a strike. Now the problem is: I have never been hit, therefore I am doing the right thing. :-) Or, I have insurance, so what does it matter? Thus the issues are answered? 73, Bill K9YEQ -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of David Gilbert Sent: Tuesday, April 18, 2017 2:26 AM To: Rick Dettinger Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] OT: Ground rods and concrete You also have many thousands of ham radio towers in northwest 7 land with either Ufer grounds or embedded tower bases. You tell me how many of them have exploded during lightning strikes, and how that justifies the admonition to "never encase a ground rod in a tower base". I once did an extensive internet search trying to find documented examples of concrete structures that had exploded from the inside out due to internal grounded conductors. I couldn't find a single one. Maybe you can find one, and if so I'd like to see the link. I did find several instances of damage to concrete structures from lightning hits, but all of them had external damage from simple lightning strikes. Most other damage was attributed to the fact that there wasn't any grounding at all ... i.e., an ungrounded structure on top of a concrete base. From a theoretical point of view, I could picture a discharge causing more damage from insufficient metal in the concrete rather than too much. Spread the current ... minimize the heat buildup. If you want to argue that a single ground rod in a concrete base is a poor idea, OK ... I can buy that. But these other blanket statements are garbage science.

In the early 1970?s, the power company I worked for was testing out some hollow reinforced concrete poles. There was considerable concern by the line workers that the poles might be more dangerous to work on than wooden poles, in the event of an accident. To check this, we installed one of the poles in a sub station, and wrapped a 26KV 1200 amp feeder conductor around the pole. When the station breaker was closed, the pole exploded dramatically, with a large fireball. The results might have something to do with moisture content in the concrete. The results convinced us to only use the poles on transmission lines that wouldn?t be worked hot, like we did with distribution lines. Of course, the power levels are much higher in lightening strikes. The conduction paths should similar from encapsulated ground rods in a tower base to Earth. >>> >>> 73, >>> Rick K7MW >>> >>> >>> >>>> On Apr 17, 2017, at 8:32 PM, Doug Renwick wrote: >>>> >>>> That myth refuses to die.

We had a buried cable that ran diagonally across an open green area. About 1/3 of the way across was what we called a 'hand hole', a shallow pit where a splice or repair had been done. It is back filled and, once the grass recovers, no one knows it is there. Lightning struck in the vicinity. The telco cable has the nice aluminum sheath and is well grounded. The lightning hops onto that in preference to running through the ground. The water in the hand hole exploded and left a small crater. The hole was about 2' deep and 3' x 5'. This makes perfectly good sense to me. You have water constricted into a small enclosure. The lightning electrode, in this case the telco cable, gets very hot very quickly. The water turns to steam and explodes. Nothing surprising about that. Let me also mention that the experts will tell us to not use solder on any grounding conductors as the solder will melt. Well . . . water boils at an appreciably lower temp than solder melts. What has happened to the water in the vicinity of the lightning electrode before the solder has had time to melt? As for assertions that exploding Ufer grounds are a myth, I can tell you for certain that the crater in Miami was not a myth. I kept a photo of it on my desk for a few months to show those curious. Experience tells me that Ufer grounds are, in general, a terrible idea. There is very little reason to risk a building or tower foundation to save the few $$$ of installing a correct ground system. Ufer grounds may be OK, indeed preferred, in places like West TX, NM, AZ, and parts of So CA, or in other very dry locations. But to use or recommend them in locations with much moisture is asking for trouble. In any location with much moisture, concrete will have the same water content as the surrounding soil. 73 de dave ab9ca/4 On 4/18/17 6:39 PM, Ken G Kopp wrote: > I was the first to use the term "exploding tower base" in this discussion. > The term "exploding" was probably not correct.

My intention was not to advertise an already famous person but rather to get folks more interested in learning theory. There has been so much discussion of grounding, dielectrics, antenna theory, impedance, and feedline problems which a few equations could solve quite quickly. An equation can substitute for ten thousand words. The Reflector would not be so deluged with antenna and feedline questions with just a little more theory being learned. I find the ARRL antenna books anecdotal. They give me fish but don't teach me how to fish. When I learned the antenna equations I found I could fish any way I wanted to. 73, Kevin.

I'd offer the possibility that the base exploded because there wasn't enough rebar, not because there was too much. The article itself makes the statement that faulty Ufer installations are the problem, not Ufer grounds per se.

A properly engineered and constructed Ufer ground works well but many seem to think that any amount of conductor buried in any amount of concrete in any configuration is a Ufer ground! These same people probably think that, if 120 radials make a good ground for a vertical antenna, then a single wire 120 times as long will work the same. 73, Roger From k8rgm at comcast.net Wed Apr 19 07:41:52 2017 From: k8rgm at comcast.net (ROBERT MUELLER) Date: Wed, 19 Apr 2017 07:41:52 -0400 (EDT) Subject: [Elecraft] Ground Rods and Congrete - Enough Said!

I put the original batteries back in to keep the testing the same as previously. They were a bit lower than I had previously thought, read 9V (alkaline). I put up a 20m dipole and tested it, 20m tuned up right away and I let it run for a bit. I then switched down to 40m and it tuned up right away to a 1.0:1. After switching back and forth between 40/30/20 a few times, I noticed that the relays seemed to be switching a bit slower than normal, and that the tuning power was going down to 2.0W instead of the normal 3.0W. Went to 40m again, and it started landing on the 25.4:1 SWR every try. Pulled up the battery monitor on the display, and while it was running the tuning process, the voltage was dropping down to 7.9V, and it'd stick at 25.4:1. Switched over to external power and it would properly tune 40m again on the 20m dipole without issue. The dummy load I ordered arrived today as well, and using new batteries, it will tune 1:0.1 on all bands. I'm going to chalk this up to being a low voltage situation, and hopefully it doesn't return! I appreciate everyone's suggestions. 73 > On Apr 17, 2017, at 11:35 AM, Walter Underwood wrote: > > 25.4:1 SWR is what the KX3 reads for a short or an open, if I remember correctly. > > Agreed, open it up, make sure everything is tight, include the ribbon cable. > > wunder > K6WRU > Walter Underwood > CM87wj > http://observer.wunderwood.org/ (my blog) > >> On Apr 17, 2017, at 11:20 AM, Don Wilhelm wrote: >> >> Nate, >> >> Since the problem is intermittent, I would not suspect a problem with an active component. >> >> You might want to remove the bottom cover and check to be certain the hardware on the BNC jack is tight and the LPF on the BNC connector is properly positioned.

Procrastinating only allows you to forget everything you learned the last time. Along with training yourself, you are also 'training' the connector pins into the correct locations for easier insertion the next time around. The same applies to the bent-metal covers of the KRX3, which are difficult to assemble the first time, but eventually become trained to fit each other. TL;DR version: As you get better, the job itself becomes easier as well. So do it! A few tips when replacing the KRX3: 0. Rule Zero of Elecraft assembly: All Parts Fit Exactly. If that doesn't seem to be true, you don't have the parts aligned correctly yet. 1. Install the TMP connectors *before* attempting to mate the multi-pin connectors. Use hemostats to handle the TMP connectors. 6in hemostats (aka artery forceps) are very cheap on eBay. Use the locking handles to grip the connector body at the correct angle for insertion, and feel for the center pin. Be patient. When the center pin locates correctly, the connector body will locate too. Now unlock the hemostat handles and use the tips of the jaws to push the whole connector firmly into place. You should distinctly feel the connector move inward. Again, this is all about practice. When you have learned what a correctly seated TMP connector looks and *feels* like, you won't forget. Also avoid removing or disturbing TMP connectors unnecessarily. A surprising amount of work can be done while leaving them in place - but always check them again after reassembly. 2. The multi-pin connector at the front right of the KRX3 aligns *exactly* with the edges of the vertical adapter board. Memorize what this should look like when correctly assembled. Ease this connector into place first, but don't screw anything down yet. 3. The multi-pin connector at the rear left of the KRX3 is more difficult to align. It is more difficult to see from above, and also its adapter board can move away from the vertical. To see what you're doing, remove the left side panel (see tip 5) and use a screwdriver to nudge the adapter board into the correct position. Then the KRX3 will drop easily into place. Look in from the left-hand side to check that *all* of the pins are *correctly* mated. 4. Remember Rule Zero. If the KRX3 does not drop easily into place with all connectors correctly mated, or if the long retaining screws passing through the KRX3 don't immediately find the threaded pillars below... then something is wrong. Go back. 5. Removing the side, top and bottom covers from a K3(S) is easy. If it makes some other part of the job more easy to do, then don't hesitate. Contrary to doctrine, you can use an electric screwdriver to remove cover panels without damage - but on two conditions: (a) that you use the correct Phillips screwdriver bit; and (b) you understand that an "electric screwdriver" is a small, low-power tool that nestles in the hand - not a drill-driver with a half-inch chuck! But always go back to the manual screwdriver when inserting and tightening screws. An electric screwdriver is *not* suitable for tightening these small screws because there is a great risk of over-tightening and causing damage. Over-tightened screws will also be much more difficult to remove the next time. (Even if you own an instrument-grade electric screwdriver with a clutch that is correctly adjusted for these particular screws, you will still make mistakes.) 73 from Ian GM3SEK From k2vco.vic at gmail.com Thu Apr 20 04:33:40 2017 From: k2vco.vic at gmail.com (Vic Rosenthal) Date: Thu, 20 Apr 2017 11:33:40 +0300 Subject: [Elecraft] Sub Receiver & KBPF3 In-Reply-To: <4BC5C136-7F20-4409-97F9-C7AAE44AFE02@gmail.com> References: <1492288020006-7629327.post@n2.nabble.com> <16b362ab-c44d-5c53-9f01-2cffd20f8405@montac.com> <53ca8601963148418d2445e2c9567957@Server.thorntonmostullaw.com> <00e801d2b946$5eec4f00$1cc4ed00$@verizon.net> <4BC5C136-7F20-4409-97F9-C7AAE44AFE02@gmail.com> Message-ID: <3AC11CCE-49E0-48D7-AA7E-5002D8DD8022@gmail.com> There are two 'secrets' for working on the subrx: 1. Take off the left side panel, even though you don't need to. Makes reinsertion much easier. 2. When plugging in the TMP cables, get the center conductor in before pushing hard on the outer part. If it is placed properly, it should go in with no trouble.

Contains filters -- KFL3A-250, KFL3A-6K, AND KFL3A-2.8K, is in good condition and fully functional. When I bought this rig both side panels were heavily scratched. I replaced the panels as well as most screws with stainless steel screws, and the rig is now a 9 out 10 cosmetically. Rig was back at the factory last November (11/17/2016 invoice date) and at that time was upgraded with KIO3B, KXV3B, and KSYN3A and the previously mentioned 2.8 filter. Also a number of updates were performed at that time so that when it left factory it was certified to "meet or exceed all factory specifications." [Cost of upgrades: $1,343.55.] In addition to the above, sold with following extra features: > KAT3A Auto Tuner > KPA100 100 watt amplifier module > KFL3A-250Hz KDVR > Your Price: $2,400, shipped your CONUS QTH. > > Sent from my iPhone > =========================== > Carl J?n Denbow, N8VZ > 17 Coventry Lane > Athens, Ohio 45701-3718 > > carl at n8vz.com > www.n8vz.com > EM89wh > > IRLP 4533 Echolink 116070 > > PSK and JT65 Forever! > =========================== > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html Message delivered to carl at n8vz.com > > > > ------------------------------ > > Message: 17 > Date: Wed, 19 Apr 2017 14:08:09 -0500 > From: Clay Autery > To: elecraft at mailman.qth.net > Subject: Re: [Elecraft] Sub Receiver & KBPF3 > Message-ID: <16b362ab-c44d-5c53-9f01-2cffd20f8405 at montac.com> > Content-Type: text/plain; charset=windows-1252 > > Funny....

Here is my "theory" on this OT overload thing, Ron. When the Off Topic contents of the posts become so frequent and overbearing, there appears to be a direct correlation with a void in new product announcements from the boys at Elecraft, which normally incite On Topic comments that fill this space.

That is an awful lot for a radio that is supposed to be putting out only 20. I would expect at most 2 to 3 watts drain at 20 watts TX output. Something is definitely going on here. may load While I don?t suspect the antenna, have you tried testing into a good 50 ohm dummy load to see if you can duplicate the issue? You might also look for bad solder joints between the PA transistors and the antenna. And, just in case, check to make sure there are no bad (arcing) connectors in the antenna path. Perhaps W3FPR might be around on the Easter Sunday for some suggestions? - Jack, W6FB > > On Apr 16, 2017, at 7:51 AM, Steve Kavanagh via Elecraft wrote: > > This one cropped up just today, with no significant change in my home station setup, using a K2/100 on 40m using a low inverted Vee. > > Sometimes (typically every other or every third time, but randomly), when pushing (and holding) the tune button with the power set to 11 watts or more, I get a high reflected power message on an antenna which is matched at low power. The power supply voltage reads about the normal 14V and the ammeter in the power supply is pinned at 25 A (or more) when this happens. An external SWR meter reads lots of reflected power. Everything unplugged from the rig except the power cable and the coax to the external SWR meter/antenna tuner/antenna.

The problem occurs only when using the tune button around the nominal tune-mode 20 watts, so the external SWR meter reading implies that the PA is probably oscillating at some frequency where the antenna is not matched. I haven't tried any other bands yet, but since there does seem to be RF feedback involved, I'm not sure they will tell me much of a diagnostic nature. > > Any ideas as to what might be happening and how to stop it? > > 73, > Steve VE3SMA > > From wa6nhc at gmail.com Thu Apr 20 13:42:02 2017 From: wa6nhc at gmail.com (Rick WA6NHC) Date: Thu, 20 Apr 2017 10:42:02 -0700 Subject: [Elecraft] Another really good reason to come to the Visailia DX convention this weekend...

One day I asked around the Physical Plant if any of the electricians did side jobs. One stopped by that afternoon and I explained what I wanted. He quoted me a great price and the next day after work he and another guy showed up. Less than 45 minutes later I plugged in the amp. It is amazing how quickly a pro can do the job. Sometimes it's worth the money. 73 de Chuck, WS1L On Thu, Apr 20, 2017 at 16:08 Ronnie Hull wrote: > Ted, LOL. Don't let the dragons breathe on ya!

No idea on a weight for this one. 73 charlie, k1xx From eric_csuf at hotmail.com Thu Apr 20 21:32:39 2017 From: eric_csuf at hotmail.com (Eric J) Date: Fri, 21 Apr 2017 01:32:39 +0000 Subject: [Elecraft] The K2 sure is a nice sounding radio In-Reply-To: <1873040107.860499.1492736848534@mail.yahoo.com> References: <1873040107.860499.1492736848534.ref@mail.yahoo.com> <1873040107.860499.1492736848534@mail.yahoo.com> Message-ID: I only operate CW, but I've always thought the K2 was a very pleasant radio to listen to.

I do a lot of DXing from J6. Typically the pile-ups are hundreds if not more people calling once it gets going. That 1 s-unit difference can mean the difference between working the DX or the band going out before you do. It's personal, right? Kinda of reminds me of the "I really don't need the horsepower of a corvette" argument. Yep, maybe you don't and we all can't be driving corvettes. But having one SURE IS FUN! Dr. William J.

If all you do is rag chew in low noise environments then maybe you wouldn't notice. In the noise on the low bands or if you're trying to break a pile up, that 4.5 dB means you're a lot louder than someone else. Whether that is worth the price is up to the op to decide, but the myth that the 1KW difference in power makes no difference is just that, a myth. 73, Scott N9AA On 4/20/17 9:12 PM, Terry Brown wrote: > If the new Elecraft amp is indeed 1500 watts it might be worth considering that going from 500 to 1500 watts is only about 4.5 Db or less than 1 S-unit in signal strength.

I just noticed on the cart check out that an "insurance charge" will come AFTER you submit the order? Weird. Anyone have any clue what the rate is? I don't mind paying a premium for made-in-USA products, what I don't like are surprises and obscure policies. Why can't they just state the rate (per X$) up front? Or do they have to consult the oracle to find out what the insurance rate is?

I had the exact problem several weeks ago. Every time I removed the batteries the problem would be resolved.. The problem was ultimately me being a dumb ass.. I had purchased a nice blue tooth speaker that perfectly sat on top of the KX3, however it kept sliding off. My solution was to glue a small round magnet on the front corners on the KX3 top. I also glued the same small magnet on the bottom of the radio. Well guess what, I knew better but didn't even think about magnetic shielding of the inductors in the ATU. While testing everything was fine, when I was convinced everything was ok I would place the radio back in it's operating position everything was still ok even with speaker on top, as long as I was on 20 meters, as soon as I went to 40 which could be a couple of days later.. the radio again went to 25.4:1 One magnet was not enough to do it, but when both magnets were on the top right hand corner, it was all over for the ATU.. makes 100% sense now that I know what was happening...

They were a bit lower than I had previously thought, read 9V (alkaline). I put up a 20m dipole and tested it, 20m tuned up right away and I let it run for a bit. I then switched down to 40m and it tuned up right away to a 1.0:1.

This was a problem with the speaker magnet in some KPA100s because the speaker was positioned right above the K2 VFO selection relays, before the speaker shield was made standard. 73, Don W3FPR On 4/21/2017 7:29 AM, Fred Moore wrote: > Sorry for the late response..

One of the locals has very fine antennas, but really appreciates the fact that his PW-1 can make the SWR look a 'bit' better. At my QTH, and TUNER, is absolutely necessary... but that is because I have only one antenna, and it is usable without a tuner on only one band. The internal tuners in most rigs can't handle it... the tuner in my K3, or my KAT500, are perfect on most bands. But a 30' vertical is a HUGE challenge for ANY tuner on 160... and many can't handle it on 80.

Does your 80 or 160M antenna cover the entire band with <3:1 SWR? If fact, on those bands the extra loss due to SWR is negligible with even 5:1 SWR's with usual coax. On 80M with a 5:1 SWR and 150' of RG8, TLW computes an additional loss of about 0.5 dB. The 4.5 db gain due to the extra power far outweighs the extra feedline loss. Factoring in tuner loss doesn't change the conclusions. Even on 20M, the extra loss for the above would be about 1.3 dB. My experience with ice is much different. Adding ice to a 4 el quad, the resonant frequency on 20M would shift 400 KHz (lower) giving 4:1 SWR's in the phone band. One could load it but run of the mill baluns at the feedpoint would pop at legal limit! 73 de Brian/K3KO On 4/21/2017 11:34 AM, john at kk9a.com wrote: > The KPA1500 tuner range is fine.

The hard core QRO folks are having a euphoric experience right now. Christmas in April ! Well, I think it is great that their wishes seem to have been granted. I suppose if all the stars lined up just right I could be one of them! However, like you, I have some difficulty justifying the cost/benefit. Also, I'd be hard pressed to make something like that work at this location. So, I don't need to spend a lot of time lamenting not having a bigger amp, and it really wouldn't help me "hear" any better. It is not insignificant that it will cost almost 3 times as much to gain only slightly more than 1 S unit. Then, when you factor in the question of "how often do I really need that?", the justification becomes even more obscure to me. One thing is for sure, a lot of electricians just got more work! I strongly suspect not everyone is 220 V ready! I think it is rather interesting how Elecraft has come to this point. Many years ago, I saw first hand (at Pacificon) the two amps they had as prototypes, one of which was "legal limit". Then they went silent for a good while before coming out with just the 500 watt model. I thought that was a very astute decision, but probably because it suited me perfectly. I can only guess at how this strategy evolved. I actually expected this bigger amp to come out earlier, but I do not second guess Elecraft on their decision making. They seem to be pretty capable of making very good decisions without my advice!!! The groundswell of interest in a bigger amp has been hard to ignore, and obviously they didn't ignore it! Then Eric tickles everyone's chain recently by asking "what would you want to see in a big amp?"! That doesn't even meet the definition of "foreshadowing"! It was more like "check your bank accounts folks!" Elecraft has nearly mastered the art of stimulating expectations. Have you noticed that, when something clearly doesn't fit their plans, they will quash the conversation, but when it isn't so far fetched the silence is deafening? I think they have as much fun doing this as they do designing the stuff! I can almost hear them giggling as they put together that cropped photo of the new amp! Anyway, put on your crash helmets and protective gear at their booths in Visalia and Dayton. It's going to be crowded! O.K. Now what do we talk about??? Dave W7AQK ----------------------------------------- From: Terry Brown If the new Elecraft amp is indeed 1500 watts it might be worth considering that going from 500 to 1500 watts is only about 4.5 Db or less than 1 S-unit in signal strength. If I owned the KPA 500 it would be a hard sell to get me to move to ANY 1500 watt amp.

I've been waiting on an amp with these features for a very long time. Of particular interest to me is your continued use of PIN diode T/R switching. Can you describe SWR protection to the Rx PIN diodes at the 1.5KW level? I suspect that a fast-detecting SWR switch will be the main focus of protection, as well as HV back-biasing of the Rx diodes. An open or short RF termination requires over 900V DC to keep Rx PIN diodes from going into conduction. Can you describe this area of circuit protection just a bit? Secondly, I know that fan noise is difficult to quantify in words. Anything particularly innovative you're going to minimize cooling noise? Thanks!

Then add in the superior level of support that you'll get compared to most other companies (and they're 'local' for US hams, another bonus). I've already asked to be put on the notify list and I'll likely put the order in at the first possible moment. Minor bonus for me is that I won't have to pay CA taxes by the time it comes out (I'm leaving CA) saving me almost 10%. When you need it, you need it. You can always turn a KPA1500 down, but when you're at max on a KPA500 and it isn't enough, it's over. If you're a DX'er, that's a high frustration point because almost all others striving for the rare one will be running full legal (or more). Another 4.5 db may make that difference. Technique can only take you so far, just as having power without technique can only take you so far. Good on both counts means a higher success rate. At some point in 'serious' ham life, the typical shack will be wired for 220-240V since it makes so many things simpler; that is a one time expense. Either through fortune or planning, all the components I've put up over the last ten years are capable of at least legal limit (chokes, cables, wires etc) so I'm prepositioned for full QRO. I smile when I see Wayne mention overhead... the devices are rated well above 1500 watts (each) and simple math says that 240V @ 20 A is a LOT of overhead space, even considering power supply efficiency losses (which are small with good design). While I would have preferred seeing more antenna ports (since I am used to the KAT500), it's not a deal killer (my move means new antennas, I'll make them more resonant than my current station). I'll probably do something along the lines that the K3 ant 1 will be for HF and the second antenna port will be used for the KPA500 on 6M, which is more than enough for meteor scatter or openings. The KPA1500 port one will be 160/80M and port two for 40-10M (still power limited on 60M, barefoot might be too much). That part is simple stuff to figure out.... to be determined later. I'm not concerned about the 15 db FCC limit with a K3 (life is too short for QRP) because at each level, NONE of the amps in the K line chain are being pushed to max, making IMD inherently MUCH lower. If at some point Elecraft can add/bless an external device for feedback and pre-distortion for the K3(s); that's even better. But in fairness, if one is using a QRP rig, being able to jump to legal limit in one step is a big deal. The ONE feature that makes it for me is that ALL my station elements will stay integrated; not so if another brand amp is used. This is HUGE since I operate the station remotely when I'm on the road. Everything 'just works'; the operator isn't concerned about any aspect, just click on the DX cluster spot (or net frequency) and everything is done except making the contact. For the newer ops, it didn't used to be that way, trust me, the integrated ability IS a BIG DEAL. Well done Elecraft! It's what we've come to expect and that is why we're faithful. Please pass the Kool Aid. ;-) Rick nhc On 4/21/2017 8:13 AM, w7aqk wrote: > > It is not insignificant that it will cost almost 3 times as much to > gain only slightly more than 1 S unit.

For example, Belden 9914 is rated at a maximum of 300 VRMS, which is 1800W with a 50-ohm feedline or only 600W with a 3:1 SWR. At 30 MHz, RG-8/213 style coax is typically rated at 1500W with a 1:1 SWR. It's true that you can do more than that with low-duty-factor modes like CW and SSB, but if you are running much more than 3:1 SWR you may be in danger of damaging the feedline.

The change in VFO when changing from CW to SSB should be what you have set in you CW tone. Try these two exercises. Exercise Examine what happens when switching between CW and SSB with CW WGHT VFO set to NOR and when set to OFS. * Select CW mode and tune VFO A to some even CW frequency, such as 14.050.000. * Enter the CW WGHT menu and tap the key to select VFO NOR. * Exit the menu and switch between SSB and CW modes. With VFO NOR, VFO A remains constant. * Change to VFO OFS and repeat the experiment.With VFO OFS activated, the display shows 14.050.000 minus your CW pitch Exercise What happens if two stations are using SSB and decide to switch to CW with CW WGHT VFO OFS NOR and activated. With VFO OFS NOR, each station will have to re-tune the other to hear the CW tone. With VFO OFS activated, neither station will have to re-tune. Each station?s VFO will be automatically offset by the pitch amount. If you sometimes operate mixed mode, with you switching to CW and the other station on SSB, it is best to enable VFO OFS so the other station doesn't have to retune you when you switch from SSB to CW. 73, Fred KE7X ________________________________ From: Elecraft on behalf of stengrevics Sent: Friday, April 21, 2017 8:52 AM To: elecraft at mailman.qth.net Subject: [Elecraft] Problem Setting CW Offset to Zero Reading KE7X's manual, I should be able to set the offset to zero by selecting CW WGHT from the CONFIG menu and then tapping the 5 button to select VFO nor.

I KNOW I am gonna need an external tuner with massive capability to do the same thing I am doing now.... only one tuner on the commercial market will tune my 80m loop at 1500W the way the K3s can. I didn't WANT an onboard tuner... I consider the price point fair for an amp only. It would cost me roughly that much to build one from a true kit, boards, or schematic... (Looking forward to it). Tuning full range, full-power, from 160-6m, from more than 3:1 gets expensive, big, and heavy in a hurry.... MOST folks don't need/want a tuner like that, especially if it takes more money out their pocket. Consider the on-board tuner a bonus extra... and if so inclined send up a prayer the FCC approval is rapidly forthcoming. :-) 73, ______________________ Clay Autery, KY5G On 4/21/2017 7:56 AM, Wes Stewart wrote: > A couple of points. > > If you believe that an SWR of >3 necessarily degrades the efficiency > of an antenna, you are simply wrong. > > If the "tuner" components have to be derated to this extent then > perhaps it should be called a line flattener rather than a tuner > because a lot of guys are still going to need a tuner. > > > > On 4/21/2017 4:34 AM, john at kk9a.com wrote: >> The KPA1500 tuner range is fine.

I have done many of them. Download the K2 A to B instructions and look at the first page to see the entire list of associated upgrades. The only 2 mods that are not listed there are the K2 Keying Waveshape Mod and the Extremely High Signal Handling mod (2 back to back 1N4148 diodes at the input of the IF Amp). The K2 Keying Waveshape Mod kit was withdrawn because the PIN diode is no longer available in thru-hole format, but Elecraft has a substitute that is used in new K2s. I can send you the instructions - if you want the instructions, send me a private email. With that serial number, you will find added benefit if you change the IF crystals on both the RF Board and the KSB2 option. While you have the crystals off the KSB2, it is an easy matter to change the filter capacitors to widen the OP1 filter to 2.4kHz from the older 2.1kHz bandwidth. While you are at it, change the AG Gain pot and install the Alternate AF Gain Wiring mod. I am not certain how long it would take someone to do all the mods doing it for the first time. It takes me less than a day, plus a couple hours to do the alignment and test, but then I have had a lot of practice. 73, Don W3FPR On 4/21/2017 10:59 AM, Ralph Perreca wrote: > Hi All > I purchased my Elecraft K2 several months ago Ser # 1913 firmware 1.06F 1.02 with ATU And SSB options I am considering doing the Rev A to Rev B upgrade and would like some feedback as to whether it is worth doing and why as well as approx build time for a builder with average experience I have built several small kits and the Elecraft K1 From phystad at mac.com Fri Apr 21 13:51:22 2017 From: phystad at mac.com (Phil Hystad) Date: Fri, 21 Apr 2017 10:51:22 -0700 Subject: [Elecraft] Matching range of KPA1500 Built-in Tuner Message-ID: I must have missed something to generate the exchanges on internal and external tuners and antennas with more than 3:1 SWR.

I tried the first exercise. With VFO NOR enabled, the frequency remains constant. With VFO OFS enabled, the frequency decreases by 60 KHz which, I guess, is my CW pitch. When I am operating, and i switch from SSB to CW, I have to retune which I find very inconvenient. You can lose a weak station while trying to retune. So, if I understand correctly, I should enable VFO OFS so I don?t have to retune? Or, should I set my CW tone to zero? I?m still a bit puzzled. 73, John WA1EAZ > On Apr 21, 2017, at 12:54 PM, Cady, Fred wrote: > > Hi John, > I don't know where you are seeing 50 KHz.

In-Reply-To: References: Message-ID: <1492798205568-7629726.post@n2.nabble.com> Hi, I am aware of the UPS calling their insurance "declared value". Can somebody enlighten me as to what it means? Literature by UPS is very adamant that "declared value" is not insurance. Then exactly what is it? My expectation is that if the package is damaged or lost I will receive fair compensation up to the "declared value". On the topic of Elecraft's new insurance charges, I have been told by somebody at Elecraft in the past that they are "self insured". I take that to mean that they will take their chances and absorb the loss if a package is damaged or lost. It may very well make economic sense for large shipping volumes in the long run. BTW I have *never* have anything shipped to or from me damaged or lost. Not even a scratch to the shipping carton. So the notion of UPS strongmen tossing packages around must be a myth. The same thing goes for the post office. It has become a very competitive parcel service in recent years.

This should give you much more usable SWR bandwidth for the KPA1500. Many commercial tube amplifiers will only tolerate 2:1 SWR. John KK9A >From Wes Stewart n7ws Fri Apr 21 13:11:12 EDT 2017 I'm not necessarily defining a personal situation. But almost any 80 or 160 antenna will suffice as an example. I am currently constructing a vertical for those bands. The model shows 2:1 on 160 at resonance and >3:1 just 60 KHz away and this is with considerable ground loss. Less loss would equal lower BW. With quarter wave resonance on 80 at 3.6 MHz it exceeds 3:1 at 3.8 MHz and is nearly 7:1 at 4.0. Transmission line loss is a non-issue with 7/8" Heliax.

They are going to charge more for something that is hugely valuable. To me the problem is not so much damage in transit but loss of the package. I have had two incidents at my home where things went awry. In one case they said a package was delivered, but I never saw it. On another occasion (just this week) a package was left at the wrong address. Fortunately, my neighbor saw that and brought it over so there was no loss. There is less risk of a package being misdelivered when a signature is required. If a package is misdelivered, who is to say what happened. The shipper will not admit to misdelivery, and it may come down to a mysterious criminal stealing it from your doorstep.

Hi, I am aware of the UPS calling their insurance "declared value". Can somebody enlighten me as to what it means? Literature by UPS is very adamant that "declared value" is not insurance. Then exactly what is it? My expectation is that if the package is damaged or lost I will receive fair compensation up to the "declared value". On the topic of Elecraft's new insurance charges, I have been told by somebody at Elecraft in the past that they are "self insured". I take that to mean that they will take their chances and absorb the loss if a package is damaged or lost. It may very well make economic sense for large shipping volumes in the long run. BTW I have *never* have anything shipped to or from me damaged or lost. Not even a scratch to the shipping carton. So the notion of UPS strongmen tossing packages around must be a myth. The same thing goes for the post office. It has become a very competitive parcel service in recent years.

I just noticed on the cart check out that an "insurance charge" will come AFTER you submit the order? Weird. Anyone have any clue what the rate is? I don't mind paying a premium for made-in-USA products, what I don't like are surprises and obscure policies. Why can't they just state the rate (per X$) up front? Or do they have to consult the oracle to find out what the insurance rate is?

I had the exact problem several weeks ago. Every time I removed the batteries the problem would be resolved.. The problem was ultimately me being a dumb ass.. I had purchased a nice blue tooth speaker that perfectly sat on top of the KX3, however it kept sliding off. My solution was to glue a small round magnet on the front corners on the KX3 top. I also glued the same small magnet on the bottom of the radio. Well guess what, I knew better but didn't even think about magnetic shielding of the inductors in the ATU. While testing everything was fine, when I was convinced everything was ok I would place the radio back in it's operating position everything was still ok even with speaker on top, as long as I was on 20 meters, as soon as I went to 40 which could be a couple of days later.. the radio again went to 25.4:1 One magnet was not enough to do it, but when both magnets were on the top right hand corner, it was all over for the ATU.. makes 100% sense now that I know what was happening...

I then switched down to 40m and it tuned up right away to a 1.0:1.

The aluminum enclosure of the KX3 (KX2 etc.) will not stop a magnetic field. This was a problem with the speaker magnet in some KPA100s because the speaker was positioned right above the K2 VFO selection relays, before the speaker shield was made standard. 73, Don W3FPR On 4/21/2017 7:29 AM, Fred Moore wrote: > Sorry for the late response..

One of the locals has very fine antennas, but really appreciates the fact that his PW-1 can make the SWR look a 'bit' better. At my QTH, and TUNER, is absolutely necessary... but that is because I have only one antenna, and it is usable without a tuner on only one band. The internal tuners in most rigs can't handle it... the tuner in my K3, or my KAT500, are perfect on most bands. But a 30' vertical is a HUGE challenge for ANY tuner on 160... and many can't handle it on 80.

My Drake L4-B would drive anything. When I decided I needed a new challenge (9BDXCC) I wanted to get on 160. Of course the Drake didn't cover 160 and my then K3, now K3S doesn't have a tuner. So I added some wire to the ends of the 80-meter inverted V. This meant that I didn't have an 80-meter antenna but the Drake would drive it anyway. Currently, with a KPA500 and KAT500 I have modest power on 160 but the KAT500 chokes on 80 at above 200-300 Watts. Hence the new vertical for next season.

Not even a scratch to the shipping carton. You have been extremely lucky. I have, on the average, one parcel a year lost or stolen in shipment - particularly foreign shipments - to the extent that I will not ship to certain countries and require insurance on all shipments. Now that Elecraft are shipping more service work and higher value (think KPA500/KPA1500) products, it makes a lot of sense to use either carrier or third party insurance rather than absorb the loss. 73, ...

All possible catastrophic load scenarios have been extensively tested. On fans: We started with a humongous custom heat sink extrusion and thick copper spreader, optimized for our packaging. We also use two LDMOS devices rather than one, allowing heat to be distributed across all that heavy metal much more effectively. This slows fan onset time. (Some competing compact amps use inadequate heat sinking, with predictable results.) Next, we added three large, deep fans. The center fan is controlled independently so it can turn on first, at low speed. In many cases that's all you'll ever hear. Only during high duty-cycle operation are the other two fans turned on. We then carefully manage the speed of all three. Ultimately, you have to get rid of the heat. But our goal is always to minimize noise. 73, Wayne N6KR > > *From: *"Paul Christensen" > > Wayne, > > Congrats on what looks like a very well-designed amp.

I ran my own 240v run as I tired of waiting five months for the $700 Electrician to show up. I think the 4 cond. No. 8 cable ran about $1.50/foot plus costs for 30A 240v twist lock connectors/outlets & 60A utility box with three breakers. I see 2v drop on 240vac under load of the 8877. KPA1500 nice design using separate 50v switching PS. Many new ham radio PA's coming out that use 50v so this could be multi-use PS. I would like a 2m 1500w sspa using LDMOS to replace the 8877 & HVPS. Not looking for that from Elecraft (I will probably buy a kit from W6PQL). PS: if I were in market for HF QRO the KPA1500 would be my choice!

I don?t consider this a negative. 1. A legal limit "LOW LOSS" CCS tuner using the build methods of most typical ham auto-tuners would be large and heavy with BIG toroids or air-wound inductors and probably vacuum caps, and expensive. The usual supposed wide-range high power auto stuff is ICAS at best ? with the operative word being ?Intermittent?, unless you?re trying to boil water or vaporize circuit board traces. 2. There are many ways to bring any antenna/feedline's Z0 to something that a reasonably-sized affordable auto-tuner can handle at not too great a feed line SWR. Not the least of which is to feed a commercial old fashioned mechanical tuner with heavy-rated components that can handle the reflected power from whatever bobbie-pin you?re trying to match without just melting all the plastic in the tuner if you key down for a bit too long. The Drake L4B (and most well built tube amps) have wide range Pi-networks with heavy components (large air-wound inductors, caps, switch contacts) that can handle the stress of high SWR at the amplifier?s output. But even that won?t successfully match anything you throw at it (well, except for the Johnson Ranger, but thats not the subject). Look at the innards of an MN2000 or Millen 92200 to get a feel for it. In most cases you can use a (good, not fine junk) mechanical tuner (knobs you have to turn, meters you have to read) to set the SWR in a band to somewhere in the vicinity of 1:1 at the midpoint of operating interest, and most well made internal tuners can manage the band edges in that case ? when the load is non-resonant and presents a high SWR. I suspect a real auto-tuner that can handle just about anything at 1500 watts at key down for a long period would take at least another KPA1500 sized box.

When I decided I needed a new challenge (9BDXCC) I wanted to get on 160. Of course the Drake didn't cover 160 and my then K3, now K3S doesn't have a tuner. So I added some wire to the ends of the 80-meter inverted V. This meant that I didn't have an 80-meter antenna but the Drake would drive it anyway. Currently, with a KPA500 and KAT500 I have modest power on 160 but the KAT500 chokes on 80 at above 200-300 Watts. > > Hence the new vertical for next season. > > On 4/21/2017 11:10 AM, john at kk9a.com wrote: >> It is very easy to put a hairpin coil on your top band vertical and bring >> the resonant SWR to 1:1.

The hard core QRO folks are having a euphoric experience right now. Christmas in April ! Well, I think it is great that their wishes seem to have been granted. I suppose if all the stars lined up just right I could be one of them! However, like you, I have some difficulty justifying the cost/benefit. Also, I'd be hard pressed to make something like that work at this location. So, I don't need to spend a lot of time lamenting not having a bigger amp, and it really wouldn't help me "hear" any better. It is not insignificant that it will cost almost 3 times as much to gain only slightly more than 1 S unit. Then, when you factor in the question of "how often do I really need that?", the justification becomes even more obscure to me. One thing is for sure, a lot of electricians just got more work! I strongly suspect not everyone is 220 V ready! > > I think it is rather interesting how Elecraft has come to this point. Many years ago, I saw first hand (at Pacificon) the two amps they had as prototypes, one of which was "legal limit". Then they went silent for a good while before coming out with just the 500 watt model. I thought that was a very astute decision, but probably because it suited me perfectly. I can only guess at how this strategy evolved. I actually expected this bigger amp to come out earlier, but I do not second guess Elecraft on their decision making. They seem to be pretty capable of making very good decisions without my advice!!! The groundswell of interest in a bigger amp has been hard to ignore, and obviously they didn't ignore it! Then Eric tickles everyone's chain recently by asking "what would you want to see in a big amp?"! That doesn't even meet the definition of "foreshadowing"! It was more like "check your bank accounts folks!" > > Elecraft has nearly mastered the art of stimulating expectations. Have you noticed that, when something clearly doesn't fit their plans, they will quash the conversation, but when it isn't so far fetched the silence is deafening? I think they have as much fun doing this as they do designing the stuff! I can almost hear them giggling as they put together that cropped photo of the new amp!

The hard core QRO folks are having a euphoric experience right now. Christmas in April ! Well, I think it is great that their wishes seem to have been granted. I suppose if all the stars lined up just right I could be one of them! However, like you, I have some difficulty justifying the cost/benefit. Also, I'd be hard pressed to make something like that work at this location. So, I don't need to spend a lot of time lamenting not having a bigger amp, and it really wouldn't help me "hear" any better. It is not insignificant that it will cost almost 3 times as much to gain only slightly more than 1 S unit. Then, when you factor in the question of "how often do I really need that?", the justification becomes even more obscure to me. One thing is for sure, a lot of electricians just got more work! I strongly suspect not everyone is 220 V ready! >> >> I think it is rather interesting how Elecraft has come to this point. Many years ago, I saw first hand (at Pacificon) the two amps they had as prototypes, one of which was "legal limit". Then they went silent for a good while before coming out with just the 500 watt model. I thought that was a very astute decision, but probably because it suited me perfectly. I can only guess at how this strategy evolved. I actually expected this bigger amp to come out earlier, but I do not second guess Elecraft on their decision making. They seem to be pretty capable of making very good decisions without my advice!!! The groundswell of interest in a bigger amp has been hard to ignore, and obviously they didn't ignore it! Then Eric tickles everyone's chain recently by asking "what would you want to see in a big amp?"! That doesn't even meet the definition of "foreshadowing"! It was more like "check your bank accounts folks!" >> >> Elecraft has nearly mastered the art of stimulating expectations. Have you noticed that, when something clearly doesn't fit their plans, they will quash the conversation, but when it isn't so far fetched the silence is deafening? I think they have as much fun doing this as they do designing the stuff! I can almost hear them giggling as they put together that cropped photo of the new amp!

That being said, a proper station antenna system is (should be) well above this price point... look at the current cost of new towers ($12-17k) before adding antennas ($1.2-5k)... In the whole scheme of things... this is a bump, not an impediment for building up a serious station. If it is something you truly want to do and you're going to 'do it right', you'll figure out how to get it done. Are there cheaper options? Sure, but what is the hidden cost; things like integration, simplicity of use (NEVER underrate that) and reliability factor in? The older I get, the more I value simplicity. Being fully integrated to me means, click to QSY then everything is done, make the call and is worth some initial 'trouble' (setup, programming, maintenance) and expense. Will I ever build an ICBM (bigger than big gun) station? Nope, but I can use what I have to make the best I can.

The basic concept is pretty simple, but as always the devil is in the details.

I know that the real weak spot amongst the high power solid state amps available to the Amateur community has been high IMD, due to what I understand are limits to the existing DMOS chips.

Message-ID: Content-Type: text/plain; charset=UTF-8 Hello group, I am considering ordering some equipment from Elecraft that totals around $2700 or so. I just noticed on the cart check out that an "insurance charge" will come AFTER you submit the order? Weird. Anyone have any clue what the rate is? I don't mind paying a premium for made-in-USA products, what I don't like are surprises and obscure policies. Why can't they just state the rate (per X$) up front? Or do they have to consult the oracle to find out what the insurance rate is?

I had the exact problem several weeks ago. Every time I removed the batteries the problem would be resolved.. The problem was ultimately me being a dumb ass.. I had purchased a nice blue tooth speaker that perfectly sat on top of the KX3, however it kept sliding off. My solution was to glue a small round magnet on the front corners on the KX3 top. I also glued the same small magnet on the bottom of the radio. Well guess what, I knew better but didn't even think about magnetic shielding of the inductors in the ATU. While testing everything was fine, when I was convinced everything was ok I would place the radio back in it's operating position everything was still ok even with speaker on top, as long as I was on 20 meters, as soon as I went to 40 which could be a couple of days later.. the radio again went to 25.4:1 One magnet was not enough to do it, but when both magnets were on the top right hand corner, it was all over for the ATU.. makes 100% sense now that I know what was happening...

The aluminum enclosure of the KX3 (KX2 etc.) will not stop a magnetic field. This was a problem with the speaker magnet in some KPA100s because the speaker was positioned right above the K2 VFO selection relays, before the speaker shield was made standard. 73, Don W3FPR On 4/21/2017 7:29 AM, Fred Moore wrote: > Sorry for the late response..

One of the locals has very fine antennas, but really appreciates the fact that his PW-1 can make the SWR look a 'bit' better. At my QTH, and TUNER, is absolutely necessary... but that is because I have only one antenna, and it is usable without a tuner on only one band. The internal tuners in most rigs can't handle it... the tuner in my K3, or my KAT500, are perfect on most bands. But a 30' vertical is a HUGE challenge for ANY tuner on 160... and many can't handle it on 80.

All possible catastrophic load scenarios have been extensively tested. On fans: We started with a humongous custom heat sink extrusion and thick copper spreader, optimized for our packaging. We also use two LDMOS devices rather than one, allowing heat to be distributed across all that heavy metal much more effectively. This slows fan onset time. (Some competing compact amps use inadequate heat sinking, with predictable results.) Next, we added three large, deep fans. The center fan is controlled independently so it can turn on first, at low speed. In many cases that's all you'll ever hear. Only during high duty-cycle operation are the other two fans turned on. We then carefully manage the speed of all three. Ultimately, you have to get rid of the heat. But our goal is always to minimize noise. 73, Wayne N6KR > > *From: *"Paul Christensen" > > Wayne, > > Congrats on what looks like a very well-designed amp.

I don?t consider this a negative. 1. A legal limit "LOW LOSS" CCS tuner using the build methods of most typical ham auto-tuners would be large and heavy with BIG toroids or air-wound inductors and probably vacuum caps, and expensive. The usual supposed wide-range high power auto stuff is ICAS at best ? with the operative word being ?Intermittent?, unless you?re trying to boil water or vaporize circuit board traces. 2. There are many ways to bring any antenna/feedline's Z0 to something that a reasonably-sized affordable auto-tuner can handle at not too great a feed line SWR. Not the least of which is to feed a commercial old fashioned mechanical tuner with heavy-rated components that can handle the reflected power from whatever bobbie-pin you?re trying to match without just melting all the plastic in the tuner if you key down for a bit too long. The Drake L4B (and most well built tube amps) have wide range Pi-networks with heavy components (large air-wound inductors, caps, switch contacts) that can handle the stress of high SWR at the amplifier?s output. But even that won?t successfully match anything you throw at it (well, except for the Johnson Ranger, but thats not the subject). Look at the innards of an MN2000 or Millen 92200 to get a feel for it. In most cases you can use a (good, not fine junk) mechanical tuner (knobs you have to turn, meters you have to read) to set the SWR in a band to somewhere in the vicinity of 1:1 at the midpoint of operating interest, and most well made internal tuners can manage the band edges in that case ? when the load is non-resonant and presents a high SWR. I suspect a real auto-tuner that can handle just about anything at 1500 watts at key down for a long period would take at least another KPA1500 sized box.

When I decided I needed a new challenge (9BDXCC) I wanted to get on 160. Of course the Drake didn't cover 160 and my then K3, now K3S doesn't have a tuner. So I added some wire to the ends of the 80-meter inverted V. This meant that I didn't have an 80-meter antenna but the Drake would drive it anyway. Currently, with a KPA500 and KAT500 I have modest power on 160 but the KAT500 chokes on 80 at above 200-300 Watts. > > Hence the new vertical for next season. > > On 4/21/2017 11:10 AM, john at kk9a.com wrote: >> It is very easy to put a hairpin coil on your top band vertical and >> bring the resonant SWR to 1:1.

What matters is that Elecraft, a company that is greatly respected, has introduced a fabulous product. They are such a good company. And while I'll not be upgrading my KPA500/KAT500, I've got to give them credit for taking the worry and frustration out of buying equipment because the quality is so high. Maybe when I was building my station I would have gone for the KPA1500. Maybe. Really- any 1500w amp is beyond what I need for my purposes. But you've got to hand it to Elecraft. Go ahead and hit the ball out of the park: Every. Single. Time. And my praise includes the little bit of support I needed. So even if you do not want this amp... just celebrate it anyway. There's not many companies like Elecraft in or out of ham radio.

That's also my opportunity for a tower and decent antennas, so I'm excited that a KPA1500 can be in the future. I'll miss out on intro pricing though as it'll be a while before we're built with antennas in and I can't make good use of a linear at the current QTH.

The hard core QRO folks are having a euphoric experience right now. Christmas in April ! Well, I think it is great that their wishes seem to have been granted. I suppose if all the stars lined up just right I could be one of them! However, like you, I have some difficulty justifying the cost/benefit. Also, I'd be hard pressed to make something like that work at this location. So, I don't need to spend a lot of time lamenting not having a bigger amp, and it really wouldn't help me "hear" any better. It is not insignificant that it will cost almost 3 times as much to gain only slightly more than 1 S unit. Then, when you factor in the question of "how often do I really need that?", the justification becomes even more obscure to me. One thing is for sure, a lot of electricians just got more work! I strongly suspect not everyone is 220 V ready! >>> >>> I think it is rather interesting how Elecraft has come to this point. Many years ago, I saw first hand (at Pacificon) the two amps they had as prototypes, one of which was "legal limit". Then they went silent for a good while before coming out with just the 500 watt model. I thought that was a very astute decision, but probably because it suited me perfectly. I can only guess at how this strategy evolved. I actually expected this bigger amp to come out earlier, but I do not second guess Elecraft on their decision making. They seem to be pretty capable of making very good decisions without my advice!!! The groundswell of interest in a bigger amp has been hard to ignore, and obviously they didn't ignore it! Then Eric tickles everyone's chain recently by asking "what would you want to see in a big amp?"! That doesn't even meet the definition of "foreshadowing"! It was more like "check your bank accounts folks!" >>> >>> Elecraft has nearly mastered the art of stimulating expectations. Have you noticed that, when something clearly doesn't fit their plans, they will quash the conversation, but when it isn't so far fetched the silence is deafening? I think they have as much fun doing this as they do designing the stuff! I can almost hear them giggling as they put together that cropped photo of the new amp!

When you adjust power, the * in the display tells you that you are adjusting the level when the KPA is in operate mode. If you put the KPA in standby you?ll notice that the * goes away and the K3 will revert to the power level you set with the amp off/in stby. If you have ?PWR SET? to PER BAND it will remember the drive level on each band. This assumes you have the amp connected to the K3 with the appropriate cable that passes the AuxBus messages.

Boehner MD) Date: Fri, 21 Apr 2017 21:36:25 -0400 Subject: [Elecraft] KPA-1500: Gain Mod when FCC Lifts 15db Rule Message-ID: <007501d2bb08$dc01be80$94053b80$@yahoo.com> Kevin, The current FCC rules for certificating a linear amplifier in the US (in order for a manufacturer to sell them in the US) is described in Part 97: http://www.arrl.org/part-97-text . Go down to 97.315 and 97.317. The 15 dB rule is 97.317 (2). The history of this rule comes from preventing the use of amateur radio amplifiers to be used in the class D Citizens Radio Service. Prior to the rule change in 2006, amps could not be sold in the US that would amplify frequencies between 24-30 MHz. The individual ham would have to do the modification themselves (or have someone do it for them), and could only receive this modification information if they could prove that they had a valid FCC Amateur Radio license. For example, my Alpha had a numerical code sequence tied to the serial number that was given to me after proof of licensure, one of my MFJ mobile amps had a modification kit, and another required wiring changes. So, two conditions had to be met - no amplification above 24 MHz, and the amp could not have a gain of more than 15 dB. Again, this prevented, or attempted to prevent, those in the Class D Citizens radio service from amplifying their 5 watt transceivers to the full amateur radio legal limit. Blocking 24-30 MHz from amplification was a bit of a hardship and an unnecessary rule for the amateur radio service. To simplify, the FCC instituted a rule change in 2006, ruling that amateur radio amplifiers just must have zero gain from 26-28 MHz. However, the FCC did not remove the 15 dB rule at the time of that rule change, which most agree is also totally unnecessary. Expert Linears and the ARRL have both petitioned the FCC to remove the 15 dB rule. These petitions are still currently pending FCC review and action. Should the FCC delete the 15 dB rule, amplifier manufacturers will be able to build amps that will only require QRP power to obtain full legal limit power, and be able to obtain FCC type certification to sell them in the US. The question posed was whether Elecraft will offer a modification program, a kit or modification instructions should the 15 dB rule be deleted. The answer, of course, was TBD. For Elecraft, this means a KX3 or a KX2 could be amplified to full legal limit. So, this is the history as I know it. I'm sure if I have anything wrong, There will be more reply posts on this subject than Wayne received after his KPA1500 announcement last evening!

The problem is with resistive losses. The day we have room-temperature superconductors, we will have efficient small transmitting loops. Until then, only a few percent of the power applied is radiated. For now, they are great when simplicity of setup allows operation where otherwise nothing could be done. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Phil Hystad Sent: Friday, April 21, 2017 7:45 PM To: Eddy Avila Cc: Elecraft Subject: Re: [Elecraft] Experiences using a portable HF loop The May 2017 QST not only does a review of the Elecraft KX2 but it reviews the Alpha Antenna, 10-40 meter support.

The SWR on 40 meters approaches 100:1 (the line is short, but I am still eating about 2.2 dB loss). Anyway, this presents a very difficult problem for most tuners -- and if you try it with an unbalanced tuner plus balun, even a 5kW DXE balun gets too hot quickly. My solution was to cancel the reactance by switching in external capacitance or inductance as needed on 'difficult' bands (40 and 30 meters) and then letting a commercial autotuner take it from there. Some day I'll put the matching circuits at the antenna and get the 2.2 dB back. Vic 4X6GP > On 21 Apr 2017, at 22:59, GRANT YOUNGMAN wrote: > > 2. There are many ways to bring any antenna/feedline's Z0 to something that a reasonably-sized affordable auto-tuner can handle at not too great a feed line SWR. Not the least of which is to feed a commercial old fashioned mechanical tuner with heavy-rated components that can handle the reflected power from whatever bobbie-pin you?re trying to match without just melting all the plastic in the tuner if you key down for a bit too long.

But if you do a survey of other high-quality no-tune (both solid and hollow-state) amplifiers, you will find that Elecraft's pricing is quite reasonable. And you get the integration and good service as a bonus. I suspect they will do quite well with this product.

It does nothing to improve the SWR at the antenna or to protect your coax. Well, it might incrementally improve the loss in the coax because the reflected wave from a high SWR antenna would not be the-reflected at the amp. It would be fully absorbed into the amp which is well matched. The really good thing that the internal tuner does is make life easier for the amp. You will get more power out because the protection circuits don't have to protect the amp. I'd be far more protective of my amp than my coax!

Will there be a change tot he K3 firmware to support the KPA1500? When a KPA500 is attached to the K3, the K3 knows if the KPA500 is on and active and changes the drive level accordingly, however should a KPA1500 be attached as well, the K3 will have to know which amp is active and on which antenna port (and band) if more than one is present as in the case of the ATU board. Is this a feature in the to do list or does it actually exist but no one has seen / used it yet. The same could have been said if two KPA500 where attached. I am considering a KPA1500 but having in the last 6 month bought a SPE 1.3k FA and got to like it. Now I am not sure what to do. What I like about the SPE is the two i/p and four antenna ports. What I like about the KPA1500 is the full integration both electrically and ergonomically as well as the pin diode switching. The slight increase in power is not an issue. If I didnt have the SPE i would definitely have had a KPA1500 to go with the K line (Kpod,K3,KAT500,KPA500,P3). Now I have to think of part chopping the SPE! 73 de Tony G6GLP --- This email has been checked for viruses by AVG. http://www.avg.com From ve9aa at nbnet.nb.ca Sat Apr 22 09:31:45 2017 From: ve9aa at nbnet.nb.ca (Mike Smith VE9AA) Date: Sat, 22 Apr 2017 10:31:45 -0300 Subject: [Elecraft] Signing your posts, KPA1500, KPA500 Message-ID: <001b01d2bb6c$c9a2afb0$5ce80f10$@nbnet.nb.ca> I have very much enjoyed the recent flurry of posts wrt the KPA1500 (well done Elecraft). One semi-related thing I have noticed. (simply due to the sheer volume of posts this weekend I suppose) There are one or two fellas who consistently post (often MANY times a day) without so much as a name or callsign attached to their posts/emails. One can do a google search of their email and posts on other ham radio sites and eventually figure out who there are, but I find it very annoying to constantly see (often) one or two lines emails, comments and/or questions without a name and better yet, any callsign attached. I am not talking about occasionally forgetting. I am talking about constantly. Are you ashamed of your name or call? Are you simply trolls? Anyways. A very happy K3 owner here. Now I am thinking about a KPA500 in the car and down the road maybe a KPA1500 on the desk. Thanks all !

If you use the suggestion that the loop perimeter (circumference for a circular loop) be 1/10 of a wavelength, then efficiency is quite low - on the order of 10%. This is the guidance given for small receiving loops to get the best nulls. However, a transmitting loop can have a perimeter of up to 1/3 wavelength and still have a constant current throughout its length (within 1% per John Kraus). This constant loop current is what defines a magnetic loop. > The problem is with resistive losses.

My loops are typically a bit short of 1/3 wavelength at the high frequency of the tuning range, and no less that 1/10 wavelength at the low end. The efficiency of a 3/10 wavelength loop, for example, is in excess of 90% provided the resistances are kept low. I typically use the outer (shield) of hard line for the loop conductor and a series vacuum variable capacitor for remote tuning. It is also possible to use multiple turns to reduce the size of a magnetic loop even further. There is an example of a 40-80 meter mag loop on my QRZ page that uses 7/8-inch hard line in a two-turn configuration. Even though only 4.5 feet in diameter, it works quite well when compared to a typical back yard inverted vee or low dipole, and it can be hidden in an attic, the back of a garage, or tucked out of sight among trees or bushes. 73, Gus Hansen KB0YH From mbabineau at magma.ca Sat Apr 22 10:35:46 2017 From: mbabineau at magma.ca (Michael Babineau) Date: Sat, 22 Apr 2017 10:35:46 -0400 Subject: [Elecraft] Experiences using a portable HF loop Message-ID: I agree with almost everything that Ron says in the post, except I would substitute the statement "The very BEST magnetic loops are incredibly inefficient? with ?The very BEST magnetic loops are incredibly inefficient on the lower bands?. Pretty much all of the Magnetic Loops on the market are around 1 meter in diameter, which means that circumference of the radiator is about 10 feet. This size of loop if well constructed can have efficiencies approaching 90% on 10m and something in the range of 30 to 40 % on 20m, so they will work reasonably well on these higher bands. The wheels start to fall off on 30m and especially 40m, where typically you would be looking at single digit efficiencies. This is really not surprising, if you put a 10 foot vertical on 40m you are going to find that it is not very efficient either ! If you had a 2 meter diameter loop then efficiencies on 40m and 30m would be significantly improved, but you would lose the ability to resonate it on 10m/12m and likely on 15m and 17m too. What a 1 meter diameter Magnetic Loop has going for it is extreme portability (at least for those with a foldable radiator), quick deployment (typically < 5 minutes for something like the Alex Loop), ground independence (no need for radials), some bi-directionality in the plane of the loop but more significantly a very deep null broadside to the loop which can be effective at killing a noise source. It also typically provides continuous band coverage from 10m through 40m with 2:1 SWR bandwidths for a well constructed loop around 100+ Khz on 10m dropping to something around 10 Khz on 40m, all in a very small package. It is both a reasonable DX antenna on the higher bands as well as a usable NVIS antenna on 40m. As with any antenna they work better if higher, but as a minimum they must be 1 loop radius above ground, so mounting on a lightweight camera tripod works ok. It is possible to make NVIS QSOs on 40m using only a few hundred mW of power, often with surprising signal strength, so putting 5 or 10 watts into an antenna with 5% efficiency can still yield a usable signal. Cheers Michael VE3WMB P.S. The secret to squeezing out the best performance when building a loop is having a solid conductor that is welded/soldered to the tuning capacitor (you need to try to avoid mechanicalconnections as they add resistance) and using either a split stator or butterfly air variable capacitor or a vacuum variable capacitor. Cheap capacitors with wiper contacts on the rotor will kill your efficiency. The radiation resistance of a Magnetic Loop is low (typically less than a few ohms) and it drops as you press it into service on lower frequencies. Even small additional resistances add up and become significant when compared to the radiation resistance on the lower bands and this is what causes the Loop efficiency to go down the toilet. >From: "Ron D'Eau Claire" > >Subject: Re: [Elecraft] Experiences using a portable HF loop >Date: April 21, 2017 at 11:00:09 PM GMT-4 >To: "'Phil Hystad'" >, "'Eddy Avila'" > >Cc: "'Elecraft'" > >The very BEST magnetic loops are incredibly inefficient, yet like any >"incredibly inefficient" antenna one can make amazing contacts on them when conditions are right. >The problem is with resistive losses.

Definitely not the properly constructed versions. The loop on the left is for transmitting, and is 2" diameter tubing. Yes, I have some weed removal due. :) Not all loops are created equal, with minimal resistive losses and a well designed capacitor/tuning mechanism they can be relatively efficient. This one is quite good on 20, and better on 40 than any traditional wire antenna I could setup with the yard and lack of trees. A halfwave dipole a halfwave up on 40m would outperform it by 4dB or so. No way I could get an antenna like that setup. The trade-off is of course being extremely high q, a very narrow bandwidth. Hence the RX loop on the right. https://goo.gl/photos/PExWyEYZmtVQDSgf7 The downside is the weight and bulk, a small transmitting loop made out of some coax is going to be down on efficiency significantly, and even low wire antennas probably will outperform them. Sure are easier to setup when you don't have trees around, however. Just wanted to make sure people understand STLs are not necessarily low efficiency, just certain designs are, and the portable models I've seen all fall in that category.

The standard side panel feet work great when the boxes of a K-line are placed in the order shown in the ad's. However, when you go to a 2-radio configuration for SO2R, you probably want the most often looked at, or touched, front panels close together in the middle. The quick pace of SO2R operations really demands the very best ergonomics that you can achieve. I currently have the two transceivers in the middle for easy access to the knobs, with the P3's immediately to the right and left of the two radios. That means on the right hand side, the boxes are in the standard "K-line" order, but on the left hand side, the transceiver handle is free to scratch the neighboring P3. That is what actually happened, but it could have been a speaker or other box getting scratched. With the two transceivers side-by-side in the middle, the side feet of the left-hand radio are positioned next to the handle of the right-hand radio, but they are thinner than the handle, and there is the potential for the handle to scratch the left-hand radio in spite of the feet. I realize that most people are not interested in dual-radio configurations, but some may have their own reasons for placing their boxes in a unique order. It seems to me that the handles could be redesigned so as to have no sharp edges that can cause scratches, or even better, redesigned so at to incorporate rubber bumpers. Also, the standard side panel feet could be made slightly thicker (i.e. thicker than the handles) , and/or available as add-on options for those who don't use the standard box ordering. Just an idea, and I am not holding my breath. In the meantime, I may go with removable stick-on feet, whether the common non-durable types or the better quality ones suggested by Clay. (In his original suggestion it was not clear to me that they were easily removable.) As to glue remaining after a cheap rubber foot has fallen off, I have in the past been successful removing it with denaturated alcohol, but the paint was left slightly dull. That was on a "Fine Junk" box, and I would not be surprised it the high quality Elecraft paint stands up much better. Goo Gone may be better, but I think the dullness was caused by the glue reacting with the inferior paint, not the alcohol, as surrounding areas touched by the alcohol did not become dull. Not lacking solutions here, just in the mindset of discussing ideals. My comment was triggered by the image showing the KPA1500 handle. It was not intended to detract from the fact that the KPA1500 comes so close to so many of our wishes for the ideal legal power amplifier, including my own. I really believe the KPA1500 fills a need, and that the price is reasonable for what it is. For me it is not immediately affordable, but that is a separate issue.

It depends among other things on whether or not you have a way to hang the wire at a reasonable height. Typically useless on the beach, for example, unless you pack a pole or two to get it up in the air, which means guys and all the rest. Doable, of course, but a lot of junk to tote around even if you have relatively compact extendable poles, plus the time to put it up. Poles/guys can be a problem when there are a lot of people around (beach/park/etc) or children who will be attracted to them like a magnet to trip over, etc.. You get the picture. It?s these kinds of situations where the loop shines. Stick it on a table or light tripod and you?re on the air in 5 minutes. With my KX3, depending on where I?m going and what the landscape looks like I use one or more of various wires, Buddipole hardware (light weight mast, shock cord whip, miscellaneous bits), or an AlexLoop. I?m currently waiting delivery on a W4OP loop. The best I can say about any of these options is that if it?s what you have, use it. They all work, sometimes surprisingly well. After a couple of years of this, I can?t say definitely which is always ?best?. I?m getting too old and decrepit to still be much of a hiker, so I?m generally driving somewhere and walking a relatively short distance to a picnic table in a park, down to the neighborhood dock, or the beach, etc. The AlexLoop is very light to carry, but a downside is that it does NOT have any sort of tripod or table mount. You?re on your own jury rigging something out of PVC and clamps to hold it up, or conjuring something that can screw into a tripod, etc. (there are plans on the web). None of it is rocket science, but it isn?t just a standard part you can purchase. > Greetings all, I'm curious to hear from anyone using a portable HF magnetic loop.

If you can install a horizontally polarized antenna 0.1 wavelengths high or higher, its efficiency is superior to field expedient vertically polarized antennas such as "magnetic" loops. This is why end-fed half wavelength (EFHW) horizontally polarized antennas are so popular with QRP back packers where efficiency is very important. On a mountaintop, a relatively low EFHW antenna can produce astounding QRP results. These affects are very easily observed (and measurable) with a 200 milliwatt WSPRlite transmitter and a USB battery that will easily fit on your pocket. On the other hand, vertically polarized antennas -- such as small "magnetic" loops -- produce significant low angle radiation even at very low heights. Unfortunately they also suffer from proximity to lossy earth. They really excel at a salt water beach (but you must be very close to salt water) or in a salt marsh (not a particularly pleasant place to take your family or girlfriend,,,). 73 Frank W3LPL ----- Original Message ----- From: "GRANT YOUNGMAN" To: "Elecraft" Sent: Saturday, April 22, 2017 5:36:33 PM Subject: Re: [Elecraft] Experiences using a portable HF loop A wire will not always outperform a loop. It depends among other things on whether or not you have a way to hang the wire at a reasonable height. Typically useless on the beach, for example, unless you pack a pole or two to get it up in the air, which means guys and all the rest. Doable, of course, but a lot of junk to tote around even if you have relatively compact extendable poles, plus the time to put it up. Poles/guys can be a problem when there are a lot of people around (beach/park/etc) or children who will be attracted to them like a magnet to trip over, etc.. You get the picture. It?s these kinds of situations where the loop shines. Stick it on a table or light tripod and you?re on the air in 5 minutes. With my KX3, depending on where I?m going and what the landscape looks like I use one or more of various wires, Buddipole hardware (light weight mast, shock cord whip, miscellaneous bits), or an AlexLoop. I?m currently waiting delivery on a W4OP loop. The best I can say about any of these options is that if it?s what you have, use it. They all work, sometimes surprisingly well. After a couple of years of this, I can?t say definitely which is always ?best?. I?m getting too old and decrepit to still be much of a hiker, so I?m generally driving somewhere and walking a relatively short distance to a picnic table in a park, down to the neighborhood dock, or the beach, etc. The AlexLoop is very light to carry, but a downside is that it does NOT have any sort of tripod or table mount. You?re on your own jury rigging something out of PVC and clamps to hold it up, or conjuring something that can screw into a tripod, etc. (there are plans on the web). None of it is rocket science, but it isn?t just a standard part you can purchase. > Greetings all, I'm curious to hear from anyone using a portable HF magnetic loop. I've read the theory behind them so I'd like to hear your opinion about them?

The maximum power transfer theorem is a complete red herring in this sort of situation. For example, on the top of page 12 of the third edition of the Art of Electronics, immediately after setting the maximum transfer theorem as an exercise, they point out that ordinary output stages are operated far from that condition. The only case in which you might get reverse termination, is if there was a (typically ferrite) isolator. In that case, the PA wouldn't care about the mismatch (at least not for an ideal isolator), but the terminating resistor in the isolator might glow red or white if you shorted or opened the output. In practice they are normally microwave devices, but I suppose they may be used in professional HF systems. In real systems, most of the reflected power bounces straight back out again when it hits the PA, to get another chance to be lost in the feeder, or even radiated. Of course this may cause the PA to run out of volts, or gain, and clip or distort, or exceed the safe operating area, and melt bond wires, or destroy the chip itself. -- David Woolley Owner K2 06123 On 22/04/17 05:47, John Perlick wrote: > > Well, it might incrementally improve the loss in the coax because the reflected wave from a high SWR antenna would not be the-reflected at the amp.

Just put the pieces between the gear that need contact protection. I do not personally have the problem, so this is just a suggestion for those who do. If you normally use the tilt stand, cut the plywood so it is shaped to sit on the desk/shelf and the top is angled the same as the top of the equipment. I would think the top of the plywood separator should be a bit below the top of the equipment. Just an idea, implementation is left to "the student". 73, Don W3FPR On 4/22/2017 6:02 PM, Bill Johnson wrote: > How about a small block under the soft handle?

It takes some patience to tune but I?ve worked a fair amount of both domestic and dx with these loops. The AlexLoop is best on 20 and higher, and I use an inexpensive Vivitar tripod VIV-VPT-1250 and it works fine to elevate the loop, and is super lightweight. I use the loops on SOTA outings especially if there?s no easy way to put up a wire. They can be as effective as a vertical in the right environment and a lot easier to put up. They also exhibit some directivity an as they can be rotated to null noise or unwanted signals out. One more nice trick in the antenna bag.

In some informal testing comparing a 6 foot diameter loop and a 1/4 wave wire antenna (40 meters) using a car chassis as a counterpoise, the loop beat the wire by 5dB (NVIS path) (C/N on spectral display). How efficient is the loop? I don't know - not as efficient as a 4" diameter copper pipe 6 foot loop, but I do know it's relative ;) A mobile whip is *very* inefficient. The loop in this case is generally *less* inefficient :) You can make contacts on both. K4HKX did a very detailed comparison of loop antennas with full dipoles and other HF antennas. He posted his results here: qrz.com/db/k4hkx Very interesting read. I'm playing around with a mobile loop idea for 80 and 40 meters using the KX3. If it works as good as I think it will, it should give me about the same performance as adding a KXPA100 - or not... that's why playing with ham radio is fun. 73's Steve WD4SDC On Fri, Apr 21, 2017 at 9:24 PM, Eddy Avila wrote: > Greetings all, I'm curious to hear from anyone using a portable HF > magnetic loop.

In a signal generator, where source match is important, there will probably be an attenuator, or at UHF and above an isolator (terminated circulator), that dissipates returned power. Otherwise, almost all amplifiers are mismatched to returned power and simply reflect it, as does any mismatched load.

I have a small transmitting loop that is remotely tuned on ANT1 so wish to run with the ATU in bypass, but ANT2 is a EFHW which I like to have the tuner active (manual mode) for. I am wary I'll bump tune while I'm on ANT1 even after clearing match memory, thus not alerting me to a bad STL tuning solution, so having it in bypass makes a lot more sense, but I do sometimes flip to ANT2 to quickly see if signal is better and don't like having to re-enable the ATU.

I built my KX1 just over a year ago including the 80/30 option. It has worked fine till this week. I was never satisfied with the output power and decided to see if I could improve it a little. Disaster strikes, I touched something with my multimeter probe on the output transistor Q6, I think, and the smoke escapes. Oh no! I check the board and a trace is burnt between T1 pin 4 and R4 power adjust resistor, I make the repair to the board and switch on RX is ok but no TX, the side tone is working and led is doing everything it should. I have a few spares so replaced Q6 no change, then Q5 and Q4, Q5 had failed but still no output. Last go I change Q1 still zero output. I removed R4 the power adjust resistor and that showed 100 ohm down to zero. I have limited skills and equipment ( multimeter frequency counter) I checked voltages all seem ok current at RX is 0.45mA and TX 1.03mA, My main station radio can hear a signal on all bands when placed right next to the KX1 and my frequency counter says it's the correct frequency at the antenna output. My power meter is not very accurate but the needle is not moving on the meter (I checked it with another 5 watt radio). I have been looking at things for a week now and decided to order a few parts to make an RF probe that connects to my multimeter. Can someone please suggest suitable test points and some idea what to expect. In short everything is working but output power is so small I can't measure it on all bands. Any guidance/suggestions would be appreciated.

Perhaps we're just dinosaurs in today's "streamlined" world. If so, please bear with us. It takes less time for me to type the sig than it does to remove the extraneous footings added to the messages in keeping with Eric's wishes, so I don't even bother with storing one in Outlook. 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Sunday, April 23, 2017 11:49 AM To: Harry Yingst; elecraft at mailman.qth.net Subject: Re: [Elecraft] Signing your posts, KPA1500, KPA500 Not too many reading posts on this reflector who do not know what a callsign is.

Ever since I've been a Ham there are others like that. In the west in the 1950s we called them "California Kilowatts" who would brag about putting out 5 or 10 kW or more on the Ham bands. Once in a while the FCC would catch up with one. It was always good entertainment to read about it. For the rest of us, we learned that complaining "Why are you picking on me? Other kids did the same thing!" was not an excuse when we were small children.

While the filter settings mentioned in the manual will produce workable filters, the best filter alignment can be done using Spectrogram (or other audio Spectrum Analyzer) and a broadband noise generator. That will optimize the filters for your particular K2. You can download Spectrogram (either v5.17 or v16) from my website www.w3fpr.com - look for the links near the bottom of the home page. These are files local to my website and they have been scrubbed for viruses many times. Both were declared freeware just before the author stopped writing improvements and went out of business. Norton may object because it is not used frequently enough, but other anti-virus applications give them a clean bill of health. I understand that there are some copies "in the wild" that do have a virus attached to them. Instructions on how to set up and use v5.17 for the K2 filters (written by Tom Hammond N0SS (SK) can be downloaded from the Elecraft website. Google will find them for you. 73, Don W3FPR On 4/20/2017 9:32 PM, Eric J wrote: > I only operate CW, but I've always thought the K2 was a very pleasant radio to listen to.

There aren't a lot of radios that have aged as well as the K2. It's the definition of "classic". But then, what do I know?

That offset is only used when using CW in SSB mode - and it should be set to the tone you want the receiving end to hear when you switch to CW. For normal operation (not CW in SSB), the CW offset is always equal to your sidetone pitch. The transmit signal will always be at the displayed frequency. It is the receive frequency that is shifted, and you do do not have to do anything. The reason for the shift is so you can hear the other hams signal at your chosen sidetone pitch. That is also why you want to tune a CW signal to your chosen sidetone pitch (zero-beat) so you will listen and transmit on the same frequency. 73, Don W3FPR On 4/21/2017 10:52 AM, stengrevics wrote: > Reading KE7X's manual, I should be able to set the offset to zero by > selecting CW WGHT from the CONFIG menu and then tapping the 5 button to > select VFO nor.

Message-ID: There must be some sweet spot of knowledge that could be briefly reviewed to help those of us who have never owned or considered a solid state amp and are old school and not EE.. I just sold my pair of 4-1000's (clean, linear, hot, noisy, beautiful to own) and now just have the KPA 500. So I am curious: 1. What are the merits of the chosen power transistors vs. alternates on market? 2. Why two big power transistors rather than 6 smaller? 3. Have the "advantages" of tube amps been overcome at this point? what are the specs that illustrate the advantages or equivalency. Perhaps rather than bogging down the reflector, an article might be offered that captures the questions and answers of comparison between tubes and transistors and among the solid state options on the market.

John KK9A from: Jim Brown jim at audiosystemsgroup.com Mon Apr 24 23:51:41 EDT 2017 Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] The reason for using 240VAC is to reduce the IR drop in the AC line, which, BTW, is not sinusoidal, but rather pulses that charge the filter caps at the peaks of each cycle. So the drop in the wire is even greater than Ohm's law appliced to a sine wave would predict. 73, Jim K9YC From N3ND at aol.com Tue Apr 25 09:31:39 2017 From: N3ND at aol.com (Dan Atchison) Date: Tue, 25 Apr 2017 09:31:39 -0400 Subject: [Elecraft] KPA1500 LCD backlight Message-ID: <973f7a46-1562-bc3e-95b6-37fb6598ded2@aol.com> Dunno if anyone mentioned this, but the backlight for the LCD display on the KPA1500 seems to be a bluish color unlike the current K-Line gear.

Adding these would increase the size and cost of the KPA1500 for all customers, while only a small percentage would make use of them. So we feel that an external controller providing SO2R or other specialized switching would be more appropriate. KPA1500 firmware will be updated to fully support such products as we identify them. We oversized the microcontroller memory by a factor of about 8 to allow for such expansion. In addition to SO2R, there may be other gear such as antenna switches that we can directly control from the amp?s antenna and ATU switches, and status can be shown on the 32-character LCD. 73, Wayne N6KR > On Apr 24, 2017, at 8:18 PM, Jerry Muller via Elecraft wrote: > > Hi Gang: > Looking for some info.

I actuarially doubt I will see another 40 years. The synthesizer mod has met with such documented success, that I routinely advise someone looking for a used K3 not to bother unless the new synthesizer(s) are in it. Or to work a discount on any K3 without them to offset the cost of the synthesizer(s) to be done immediately. All this became apparent very early on after the new synthesizers were introduced. Anyone who is adding a KRX3 sub RX to a K3 which still has the old Synth for the main RX, I tell them to do the synth mod right then, because the easy time to do that is when the space for the sub RX is not occupied. A fully modded K3 is an awesome piece of used electronics, a very good value. I have noted, watching eBay and sales via this reflector, that compared to the overall K3 count of nearly 10,000, that only a small percentage in the low single digits appear to have come up for sale overall. These days you see one for sale every one or two weeks, which goes quickly. 25 to 50 units for visible sale out of a universe of 10,000 is a tiny number less than 1%. I'm sure there are more than that which trade privately. People sell their K3's to friends and members of their own radio club. I haven't done the new board that has the built-in sound card and USB interface. That's because I already have all the stuff working and debugged to do all those functions without that board, such as true serial cards in my PC etc. If any of that stuff gets zinged (not hoping for that), leaving others in a questionable state, I'll do a wholesale switch to the USB upgrade and remove some number of cables. Buying a K3S outright requires a financial negotiation with the war dept, and is highly unlikely unless fire or lightning has turned my K3 into an insurance reimbursement. In the meantime, my limiting factor is better 160m RX antennas to feed the remarkable sound-stage diversity possible with the K3/K3S, made even better with the new synthesizers. All this contributes to the effectively zero value of the old synthesizers. 73, Guy K2AV On Tue, Apr 25, 2017 at 12:36 PM, Michael Stringfellow wrote: > I successfully upgraded my late model K3 with the new synthesizer board > (KSYN3A) and KXV3B and have the removed boards with hardware.

At this point can't refer you to them but you can find them with some searching. A 3 dB improvement in TX strength will not be noticed either, until it is used in a situation where you're close to or in the noise. Close neighbor hams with a sequence of installing the syns, and screen prints in the reduction in phase noise sidebands for each step, and noticeable improvement in interfering with one another. For me that was the killer demo. The "news" aspect of the syns is pretty well past, so don't see much about it any more. 73, Guy On Tue, Apr 25, 2017 at 4:33 PM, Wes Stewart wrote: > I've seen these rave reviews about the new synthesizer many times.

The lower phase noise may be apparent to you when picking a station out of a pileup or on a contest weekend with many close-in signals.

It's pretty common now, especially in higher power switchers, to include power factor correction (PFC). Instead of only charging bulk caps at AC peaks when rectifiers are forward biased, the rectified incoming line hits a boost converter which smooths out the cap charging rate. For example, the Meanwell RSP-3000 48V 62A supply, includes PFC and claims power factor > 0.95. Without PFC, might be PF=0.6 and certainly operate as you describe with high current peaks, big IR drop & I2R power losses. 73, Josh W6XU On 4/24/2017 8:51 PM, Jim Brown wrote: > ...is not sinusoidal, but rather pulses that charge the filter caps at > the peaks of each cycle.

Fortunately, the contents were well wrapped with waterproof material, so no apparent damage. It's as if UPS wanted to make absolutely sure I didn't get my package quickly, or heaven forbid, early! Being somewhat cynical, I wonder if the extra delay in Phoenix was so they could let the box sit in the Arizona sun and dry out!!! I may be overlooking something, but my best experiences, by far, have been with USPS, and particularly Priority Mail. Unless a Sunday intervenes, I've never had anything take more than 3 days when shipped Priority Mail! If you can fit it into one of their flat rate boxes, you probably are way better off. Also, I've never had a Priority Mail package arrive with crushed corners as this one did! Anyway, shipping these days is expensive and risky!

I have a remote antenna switch system consisting of an Array Solutions Rat Pack with the Ten Tec interface box. This is under control of an Elecraft KRC2 unit. It saves many feet of coax and reduces the in shack cable clutter. Station is K3, KPA500 and KAT500 and more Elecraft with K2 and KX3. My issue is I'm not getting full value from the KAT500. It is capable of switching 3 antennas. But with a single feed line on position one all else is lost. So my request would be to be able select alternative programmed values by using the KAT 500 antenna switch. Any manually selected antenna would apply tuner values to the antenna position but ANT 1 would remain selected. As it is now it works but requires retuning when manually changing between selected, say, 80 meter antennas and prior values are lost. In hardware I could do it now but don't want to butcher the KAT500. Well beyond my pay grade as I do not know how much reprogramming would be required in the firmware and utility to select this as an option. This option could possibly be done in the KPA1500 too. Certainly be a plus in consideration of the KPA1500 which seems to have less in that there are only 2 antenna selections available. 73, Bob K2TK ex KN2TKR (1956) and K2TKR On 4/25/2017 4:14 PM, Bill Frantz wrote: > My most wonderful and understanding wife has requested that the number of > "wires" coming into the house be minimized.

I also have the PX3 and KPXA 100. I am happy with my setup. It is the finest rig combination that I have had in 35 years as a ham. I love it's flexibility for operating portable by using only the KX3, or with the PX3. Disassembly and reassembly of connections can get tedious when I am operating portable often and have to make the switch back and forth. I keep reading all the great things about the K3 and K3S. I also see that there are now good opportunities to purchase a used K3, many with the upgrades to make them more like a K3S. For those of you who have KX3 and a K3 that has been upgraded to have most (not sure what is not possible to upgrade) of the features of the K3S, What does the K3 as far as receive performance and other key features have, that are an improvement/enhancement over what I have with the KX3? The reason I ask, is that if I ever have additional funds available, I am trying to figure out if it would be advisable to upgrade to a used K3 that has been upgraded, and buy a P3, and use my KX combination for more portable use. I just don't know if it is worth buying a used K3 and P3 when I have the KX3 line. I know I am the one who would have to make that final decision, but I would welcome any thoughts by current upgraded K3/P3 owners who also have the KX3.

At 100W having a separate amp as part of each radio is no big deal, but at the price of a KPA1500, one really wants to pay for only one, given that SO2R means only one radio can be transmitting at a given time. I am just a beginner at SO2R, but I have already spent a lot of time thinking about various aspects of the subject. First there is the "SO2R controller" issue. There seem to be a lot of different designs out there, and they don't necessarily try to solve the same problem. Rather, different users seem to form personal opinions of what functions are to be implemented, and available implementations reflect that. Issues that may or may not be addressed in depth include routing of radio inputs, radio outputs, and radio controls, including interlocks to ensure that only one radio can transmit at a time. Second, there is the configuration of the radio boxes. Normally the two radios operate on different bands. With 5 or 6 bands used in a HF contest, there will be many combinations of band choices for two transceivers. One can set each radio manually to the proper band, but sometimes one might want to use a central control to select a combination of bands rather than individual bands. When amplifiers are added to the picture, the situation becomes more complex. I have one KPA500, on the main K3. That works well if that radio is on say 40 and the second radio is on 15, since power is often needed on the lower bands, while 15 often doesn't need much power if open. Now suppose 15 closes and I want to go to 80 with the second radio. 80 might need the amp more than 40, so how do I quickly switch the amp over to the other radio? A similar situation would exist if I had two amp's with different power capabilities. The ability to "share" one amp between both radios would be very attractive. On the other hand, if I did not have that capability, but instead had a second KPA500 in addition to my existing one, I might in a given situation want to combine both for 40 while running barefoot on 15. Clearly, it may be shortsighted to address such individual capabilities individually, and from a manufacturer's standpoint it would make sense to have a generalised scheme of configuration, maybe with GUI software that allows the user to configure things by drawing and storing interconnection schematics. Of course, that is just the control side of it. The physical switching side, with proper isolation may be both complex and expensive. Third, antenna selection. One user may use many feedlines, while another tries to use only one. Antennas themselves may be monobanders or multi. I think most of us have been struggling with how to best utilize the fixed numbers of antenna connectors on different radios and tuners. What seems like ideal features to one user may seem totally wrong to another, even in a single radio scenario. With SO2R, we want to be able to select between several different antennas used by two radios. Isolation must be excellent so that neither radio will be interfered with by the other. The antennas themselves may sabotage the isolation by their proximity and configuration. The ideal station would perhaps have separate antennas widely spaced from each other. The average ham is more likely to use fewer, multiband antennas. A typical switch box has two radio connectors and several antenna connectors, and it should not allow both radios to connect to the same antenna. In any case, the switching hardware operates at high power and is likely to be expensive. Ulitmately, it might be best seen as part of the expensive switching network that configures the radio box interconnections as discussed in the previous paragraph. To summarize, SO2R is a complex subject, and it is currently addressed mostly in a fractured way, using a conglomeration of hardware solutions to solve different pieces of the puzzle. There is such a diversity of user requirements that any "total solution" that would hypothetically be offered by any one manufacturer is likely to seem wrong to many potential customers, unless the archictecture is extremely advanced. Nevertheless, even a manufacturer that offers only pieces of the puzzle should over time gain an edge if its products supports major classes of configuration requirements. I don't know if there is room in this forum to have much discussion of what features would be appropriate in future SO2R-related offerings from Elecraft, but previous posts have started to touch on the subject. Personally I would suggest that hams like myself with limited real estate and going to SO2R are likely to be using multiband antennas but still need antenna switching other than what may exist in radios, amplifiers and tuners. In other words, discussing how many connectors a radio or tuner should have may be a dead end approach. It is interesting to note that HF antenna multiplexers allow two radios to use the same multiband antenna, and that the isolation in such a configuration tends to be much better than what is achieved with closely spaced separate antennas. The multiplexer transforms the multiband antenna's single feedline into separate connections for each band. Thus, a SO2R antenna switch as commonly used by a superstation today, with connections for two radios and several monobanders, is still appropriate for the modest station using a single multiband antenna shared between two radios. Firmware and hardware offered by Elecraft in the future for the purpose of SO2R would do well to anticipate and support such configurations. 73, Erik K7TV -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bob Sent: Tuesday, April 25, 2017 8:12 PM To: Bill Frantz ; Elecraft Reflector Subject: Re: [Elecraft] KPA 1500 - SO2R Hi Bill, No XYL requests involved but in a similar manner I have reduced the feed lines into the shack. I have a remote antenna switch system consisting of an Array Solutions Rat Pack with the Ten Tec interface box. This is under control of an Elecraft KRC2 unit. It saves many feet of coax and reduces the in shack cable clutter. Station is K3, KPA500 and KAT500 and more Elecraft with K2 and KX3. My issue is I'm not getting full value from the KAT500. It is capable of switching 3 antennas. But with a single feed line on position one all else is lost. So my request would be to be able select alternative programmed values by using the KAT 500 antenna switch. Any manually selected antenna would apply tuner values to the antenna position but ANT 1 would remain selected. As it is now it works but requires retuning when manually changing between selected, say, 80 meter antennas and prior values are lost. In hardware I could do it now but don't want to butcher the KAT500. Well beyond my pay grade as I do not know how much reprogramming would be required in the firmware and utility to select this as an option. This option could possibly be done in the KPA1500 too. Certainly be a plus in consideration of the KPA1500 which seems to have less in that there are only 2 antenna selections available. 73, Bob K2TK ex KN2TKR (1956) and K2TKR On 4/25/2017 4:14 PM, Bill Frantz wrote: > My most wonderful and understanding wife has requested that the number > of "wires" coming into the house be minimized.

Power supplies are supposed to spread the current demand over a significant part of the cycle. I believe this is done by having a relatively low value capacitor on the mains side and relying on the switching regulator to compensate for the wide voltage variations across each cycle. I believe that even applies to wall warts. This "power factor correction" will not be perfect, so the peak current will still be more than for a resistive load. -- David Woolley K2 06123 On 25/04/17 04:51, Jim Brown wrote: > The reason for using 240VAC is to reduce the IR drop in the AC line, > which, BTW, is not sinusoidal, but rather pulses that charge the filter > caps at the peaks of each cycle.

Your packing material needs to be tailored to the weight of the equipment. Packing peanuts and bubble wrap are good for articles up to about 20 pounds. With equipment heavier than that, you need something more substantial, like high density foam (not cushion grade foam rubber) to secure the equipment. Those large packing "sacks of air" are not good for anything weighing more than a couple pounds. If they receive much pressure, they will burst. Think what will happen if the package comes to an abrupt stop at the end of a sorting conveyor. I send and receive a lot of packages, and anytime I have observed damage is when the equipment inside has contacted the side of the package. I have not found that one carrier is worse than another. I use both UPS and USPS frequently, and on occasion FedEx. If you have delivery problems, blame it on the local delivery person - baring some disaster in transit. I currently have delays pending due to flooding in the area, but that kind of thing is not common. 73, Don W3FPR On 4/26/2017 9:36 AM, GRANT YOUNGMAN wrote: > This topic comes up frequently ? especially on boatanchor lists where a lot of heavy boxes get shipped around frequently. > > I?ve had substantially roughed up packages (punctured exterior cardboard, crushed corners, split seams, etc,) arrive by USPS, FedEx and UPS ? and consider them all to be equal opportunity offenders.

In my experience it?s been far more common for actual damage to the shipped item occurring as the result of sloppy, non-commercial grade, ?peanut?-style packing and the frequent use of used packing materials than by the carriers themselves.

Note: there is a separate K3S listing. Print out the first page of the Sherwood listing in landscape mode, and then fold the paper to put the two listing lines next to one another. It is quite true that many typical and ordinary ham situations will not demonstrate the difference, but weak signal work on any band, those improvements will make a difference, because phase noise is not additive, it modulates band noise. This will have more effect on signals from low signal RX antennas that are not pre-amped. My K3 with the new syns is better in sound stage diversity, but that is in the brain and I don't know the mechanism for the improvement, hence entirely subjective. I suspect something related to allowing band noise to come through less modulated by phase noise, but absolutely zero proof. On a diversity sound stage, noise is scattered around the "horizon" with some discrete noise taking fixed positions. The noise sounds less "muddy" with new syns, that's as good as I can describe that. I'm still trying to find a series of attachments showing a progression of phase noise on steady TX carrier with one at a time syn changes between two close K3 owners. I'm now thinking it was on one of those Tiny URL kinds of things and perhaps not widely distributed. I don't have email with attachments regarding that synthesizer test. And I'm one of the worst at figuring out the secret word to pump a google search. And yes, the diff in CQ shaping was obvious in seconds after syn replacement. There is some stuff on Elecraft's Nabble searchable list showing A/B keying. 73, Guy On Wed, Apr 26, 2017 at 1:20 AM, Vic Rosenthal wrote: > The improvement in QSK performance and elimination of jitter in CW timing was immediately noticeable even without an a/b test.

To correct this I added a toggle switch and mounted it to the ANT3 position. For my application, I needed a way to switch between both inputs. At least for now, I don't need the 2 meter module. Fortunately, I had spare TMP sockets and a short TMP cable that I pulled from scrapped transceivers. I soldered the sockets to the toggle switch. I plugged in two TMP cables to the outer socket. One went to the AUX BNC and the short TMP cable went to the TMP socket on the ATU. The center socket went to the Sub RCVR BNC. I wrapped toggle switch with copper tape.

Almost all packages I've received in the past few years have come via UPS and I use it myself for my occasional outbound shipments. That being said, there is a disturbing relationship between UPS and USPS: In some rural areas, and maybe elsewhere, UPS can hand off a package for ultimate delivery by USPS. Seems reasonable except that the two providers have different conditions of carriage. UPS agrees to deliver to a home doorstep while USPS requires that a home have an official USPS mailbox which they use when able. If USPS delivers a package too large for the mailbox, then they will deliver to the doorstep. However, if there is no mailbox, USPS will not deliver any package of any size. They return the package to the sender, no notice to or recourse for the intended recipient. UPS and mail-order shippers don't disclose this occasional glitch (at least I've not seen it) so both shippers and recipients get screwed. Moral of the story: If you don't have a mailbox, don't order packages that will be shipped by UPS. Better, use someone else's delivery address that has a mailbox. If you have a PO box, some US Post Offices will accept courier packages addressed to their own street address with an appended box number. But the shipper must specify that street address because UPS will not deliver to a PO Box explicitly!

I worked on it right after the purchase and then life got in the way when I was about to do the first power on testing at the end of Part 1 assembly. I built most of the added modules first thinking I would start with the smaller, less complex boards. After I retired two years later, I picked up the kit again only to realize tremors in my hands would not allow me to do the soldering any longer. At this point I have the following for sale: Basic K2 - built to Part 1 of the assembly manual pg 42 but not tested KSB2 - built - untested K60XV - built - untested KNB2 - built - untested K160RX - built - untested KIO2 - built - untested KDSP2 - un-built still in box KAT100-2 - un-built still in box I also have the Rework Eliminators with appropriate changes made to the K2 assembly to this point. EC2 - assembled - intended to have the KAT100 and KPA100 in the EC2. The KPA100 kit is not included. Also have the KRC2 - assembled and used with my K3. I have over $2000 invested. For all the above including shopping within the continental US, I am asking $1000, but will consider reasonable offers. Contact Ken Allen at kb8ke at yahoo.com with any questions or offers.

It takes advantage of "consolidator" rates, with UPS delivering pre-sorted packages to a hub Post Office for final delivery. FedEx has a similar service. E-Commerce and mail order companies love these services because they're cheap, but the typical customer service agent doesn't know the difference between "UPS Brown" (delivery by UPS) and the cheaper UPS to USPS service. Since the agent (or the website) thinks they're shipping standard Ground, they insist on a "real" address. The company then uses the cheaper service, the package hits the post office and goes back to the shipper. I've had good luck with the work-arounds in your post. I usually put things like m/s 9999 in the "company" field because some shippers "standardize" addresses, and the company name is usually unedited. If you specify "UPS Brown" and the shipper follows instructions, you'll get the package from UPS, not through the Post Office. This cheaper service is only available to larger shippers. It's not available to consumers. 73 -- Lynn On 4/26/2017 11:13 AM, Rick Tavan wrote: > The radio world seems to be converging on your opinion, Ken.

My employer had a contract with them, practically everything went overnight, and the volume was "yuuge." Nothing ever got lost. I was on the road a great deal and regularly got envelopes at hotels, and in client's and partner's facilities. I thought this was how the entire FedX world worked. After retiring and having to use the FedX Store, I discovered: It cost a LOT more to ship an envelope at the FedX Store than it did when I took it to work and shipped it with a company label. Delivery to homes seems to be random. One package was left on top of a trash toter at the road. While it was badly banged up by the trash truck, it ended up in the road and not in the truck, fortunately. Conversely, my wife and I "adopt" deployed troops and send them packages. Since we started in 2002, we've mailed hundreds ... all USPS Priority Mail. Not one has been lost, and we've gotten some photos of our troopers where we can see the package ... in about the shape it was when we mailed it. We can even track them as far as JFK where they seem to fall into a military black hole.

The later case of the expensive amplifier was just a few months ago, and it was at a "UPS store" that I understand not to be an "independent shipping center". Of course, the particular employee may have misstated the limit, or I may have misheard. Regardless, my main point is that the rule was so rigid. The fact that the employee was able to examine the empty packing materials and see that they were customized and in good contition made no difference at all. Such rigidity must surely end up costing the customer, and it is up to the customer to determine whether perceived reliability of the company is worth the extra cost. Although I have shipped many packages, I bow to your even greater experience. BTW, once I shipped a small package in the same store, in a box that was a once-used USPS Priority Mail box. The employee berated me for using that box since it was supposed to be used only for purposes of USPS shipping. I believe he was correct in that such a rule exists. It doesn't make sense for USPS to allow their freely handed out boxes to be used with other shippers. However, after the original USPS shipment had been paid for and completed, didn't I own the box and didn't I do a good deed by reusing the box? The fact that the box had been used previously for USPS shipping was plain to see. 73, Erik K7TV -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Wednesday, April 26, 2017 12:17 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] OT: Package shippers Erik and all, I believe that amount is $1000 rather than the $100 that you quoted - unless the particular packing store you used sets their own rules.

Getting old is a pain when it means we can no longer do some of the things we love to do. The price you are asking for the set of K2 items would mean you are taking quite a loss on the items you had bought. One option to consider is to find someone you know and can trust to do the soldering work for you. You can do the final assembly and alignment.

If so, check the DSP NR. If it is on, it can cause distortion. It does an effective job of reducing noise, but does introduce some distortion - and may appear intermittent depending on the signals and their level. If no KDSP2, then check the soldering in the PLL Reference area as well as the BFO area. Marginal solder connections may have been OK in the past, but can fail after time. Check the schematic for components in those areas and re-flow the soldering. You can also do the Receive Signal Tracing as indicated in the manual. You may have to connect a strong signal generator as described in the Troubleshooting section of the manual. An XG1 or XG2 will not provide a strong enough signal (the XG3 will), so construct the oscillator shown in the troubleshooting section of the manual. The power output problem may or may not be related. The best way to find the offending stage is to do Transmit Signal Tracing as described in the Troubleshooting manual appendix. When you get to a stage which produces less than the expected values, that is the output of the failing stage, and you can investigate that particular stage for the problem. Re-flowing the soldering may correct it. Component failure is not the most common cause of failure (soldering is), so do not jump to conclusions about a component being bad - exception is if one of the PA transistors has been damaged. If you find everything up to the PA transistor bases OK, then replacement of the PA transistors with the K2PAKIT from Elecraft may be in order. 73, Don W3FPR On 4/26/2017 5:19 PM, Denis Jackson wrote: > My K2 hasn't been used for a few years but, with the intention of taking it > out for a bit of SOTA work, I powered it up today.

Even if there is nobody near by, Elecraft has a list of trusted builders. Spending just a bit more to complete the radio will be a lot of value added: you'll have a great rig, and you (or your heirs) will be able to get way more than $1K for the rig. And, there are people who would do the job just for the fun of it. Plus, once the rig is finished, there is a lot of help here on this list. No question is too silly. 73 de Ray K2ULR KX3 #211 -----Original Message----- From: Jeff To: K2 ; Kevin Cozens Sent: Wed, Apr 26, 2017 6:00 pm Subject: Re: [Elecraft] For Sale, unbuilt K2 with many options Isn't there a guy on here. or used to be on here that offered his assembly services on Elecraft products?

The easy fix for this is to go online to FedEx, generate the shipment, print a shipping label, and drop it off at the FedEx store. No extra cost. The same thing works for UPS. I also ship small stuff USPS. I always pack in my own boxes (I save boxes and bubble wrap) and take them to the local post office. Never any issues. There is a special place in hell for those who ship with packing peanuts. I've opened boxes and had them blow all over my property! > Delivery to homes seems to be random.

I live on a main road in the Santa Cruz Mountains. My mailbox is one of four adjacent to my driveway. I've not had this problem with UPS, FedEx, or USPS, but I and many of my neighbors HAVE had this problem with OnTrac. I've had their packages left outside in the rain, at the edge of the road, in my driveway, sitting on the hood of my car. Neighbors have had packages left at their mailbox, which in one case is nearly a mile from their house. Many of us have told amazon to never use OnTrac, and it's a reason that I haven't signed up for amazon prime. As to delivery of UPS by USPS -- this business arrangement was established (quite publicly) several years ago, and has worked fine for me. I believe it's limited to UPS ground. 73, Jim K9YC From jim at audiosystemsgroup.com Wed Apr 26 18:33:55 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 26 Apr 2017 15:33:55 -0700 Subject: [Elecraft] A KX3 owner with a K3 or K3S question In-Reply-To: References: <000001d2be52$a344b370$e9ce1a50$@comcast.net> Message-ID: <1fca2730-f9a2-3cc8-2261-4bdf8909de54@audiosystemsgroup.com> Good observations all.

I believe it's limited to UPS ground. FedEx has th same arrangement. It's good business for the Postal Service. I recently ordered something from "the auction site" where the merchant was insistent on "we do not ship to Post Office Boxes". So I furnished the street address, albeit reluctantly because we access the "mailbox" only infrequently because of its location. What did the merchant to? Sent it to that address by USPS! 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From jmoodysr at gmail.com Wed Apr 26 19:25:03 2017 From: jmoodysr at gmail.com (Jon Moody) Date: Wed, 26 Apr 2017 16:25:03 -0700 Subject: [Elecraft] FS - KX3 Complete Base Station Message-ID: Greetings fellow Elecrafters, The PX3-F and XV222 transverter have both been spoken for.

The local post office claims to have found a rule that says that if your house is more than 1/2 mile from the public highway, they don't have to deliver packages. So to save the driver the 5 minutes it would take to drive to my door, I have to make a more than 1-hour round trip to the post office and stand in line to pick up my package. When I order on-line I always try to get it shipped FexEx, even if it costs more. Unfortunately Amazon doesn't give you the option to specify the shipping company, so I have to have everything shipped to a friend's house in case it comes by USPS.

I received a quote several years ago from one of the recognized builders but the price was about 50% of my original investment and was more than I was willing to spend. I've had the full K3 line for a number of years and love the radio, so don't really need the K2. I'm hoping to find someone who wants the K2 but doesn't have the $$ to buy new. You all are correct in saying the level of support available on this list is amazing. I have benefitted from the list many times while learning to use my K3, just by reading others posts.

Getting old is a pain when it means we can no longer do some of the things we love to do. The price you are asking for the set of K2 items would mean you are taking quite a loss on the items you had bought. One option to consider is to find someone you know and can trust to do the soldering work for you. You can do the final assembly and alignment. At least you will the satisfaction of having done some work on the K2 even if it wasn't the soldering of parts that you originally expected to be doing. You will also wind up with a nice radio that you can use on the air. -- Cheers!

A properly placed 2-stub filter using a decent RG8/213 typically provides 60 dB of attenuation at the second harmonic, that in addition to the suppression provided by the amplifier's output network. I've settled for 5B4AGN's W3NQN implementation of filter sets conservatively rated for 200W between exciter and power amp. That takes care of protecting the receiver and also killing any phase noise the other radio is producing. In my experience with SO2R and other multi-transmitter setups and all K3s, killing the amplifier's second harmonic mostly matters between 80 and 40 CW, and 40 and 20 CW, because the harmonic lands in the same part of the higher band where we want to operate. 73, Jim K9YC On Wed,4/26/2017 10:50 PM, Matthew Cook wrote: > So time to get back to working on the 1500W W3NQN filter designs... and the > high power paperwork requirements from our regulatory body to run that sort > of power level... sigh.

In some informal testing comparing a 6 foot diameter loop and a 1/4 wave wire antenna (40 meters) using a car chassis as a counterpoise, the loop beat the wire by 5dB (NVIS path) (C/N on spectral display). How efficient is the loop? I don't know - not as efficient as a 4" diameter copper pipe 6 foot loop, but I do know it's relative ;) A mobile whip is *very* inefficient. The loop in this case is generally *less* inefficient :) You can make contacts on both. K4HKX did a very detailed comparison of loop antennas with full dipoles and other HF antennas. He posted his results here: qrz.com/db/k4hkx Very interesting read. I'm playing around with a mobile loop idea for 80 and 40 meters using the KX3. If it works as good as I think it will, it should give me about the same performance as adding a KXPA100 - or not... that's why playing with ham radio is fun. 73's Steve WD4SDC -- View this message in context: http://elecraft.365791.n2.nabble.com/Experiences-using-a-portable-HF-loop-tp7629785p7629825.html Sent from the Elecraft mailing list archive at Nabble.com.

Our situation here is somewhat different regarding emergency preparedness. We are a very rural environment in SW Oregon. No cell service, frequent land line outages, very mountainous terrain and few options for communication in the event of an extreme emergency. The State of Oregon has been actively engaged with local ARES groups to prepare for an expected 9.1 subduction zone quake off of the Pacific Coast. All models point toward a complete disruption of all services for months and much of the destruction to disrupt the norm for years. Our community is isolated with the probability of all infrastructure collapsing and our demographic being physically unable to move in or out of the area except by foot. There are approximately 300 people within the thus affected zone. I am interested in opening up as much bandwidth as possible to provide maximum versatility for communication. This would include the MARS bands. We have several folks here with General and Extra class licenses. I don't think our radios should be encumbered with the limitation of band width. I suppose I could acquire the patch by some other means but I would just as soon have it from Elecraft. I have not purchased yet but I am particularly interested in the possibility of an amplifier for my radios. I wondered if the KAT500 hundred could handle more than 100 watts? In discussions with club members it is apparent that some are for and others against 1000 watt amps etc. I'm curious if the elecraft tuner has wattage limits. ----- Stan KG7FYI -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-P3-and-KAT500-tp7629969p7630020.html Sent from the Elecraft mailing list archive at Nabble.com.

Local MARS directors also typically have information on firmware loads or other common means to get a lot of radios expanded to general coverage transmit, which they provide to MARS members. And MARS does work with civilian agencies in emergencies. There aren?t really MARS ?bands? as such. But regardless of license class, an Amateur station without a MARS license is not authorized to operate on any designated MARS frequency. These frequencies are managed by DoD. The interface between MARS and the non-MARS emergency traffic is on the ham bands, not on MARS frequencies, since that is the only place both are licensed to operate. So, if they?re not, your local/state emergency coordinators should be working with the State MARS directors and their staffs to develop a plan for MARS support in the event of a natural disaster. That said, I dropped my AFMARS affilliation around 15 years ago, so maybe things have changed. And I probably don?t understand the full context of the request to begin with. > except by foot.

Having persons uninformed with net operations is totally disruptive to the point, at times, that all traffic stops. Not only will you incur the wrath of these agencies you well might incur the wrath of the FCC. Just because there is an emergency does not give you Carte Blanc to use radio equipment as ones private forum. There is, however, systems in place that welcome participation like yours. Radio Amateur Civil Emergency Service (RACES) is an organization provided for in Part 97 of the Federal Communications Commission rules and regulations governing amateur radio. RACES stations are licensed to do exactly what it seems you wish to prepare to do. I would recommend you contact the Oregon Department of Emergency Management and describe exactly what you wish to do. You probably will be surprised how receptive they will be. Our office location: 3225 State St., Room 115 Salem, Oregon 97301 Map/Directions Hours of Operation: 8 a.m. to 5 p.m., Monday - Friday The Oregon Office of Emergency Management observes all state holidays including Martin Luther King Jr. Day, President's Day, Memorial Day, Independence Day, Labor Day, Veteran's Day, Christmas Day and New Year's Day.

If you have a MARS authorization, Elecraft will provide the patch. However, you do not need it for ARES and/or RACES operations which are strictly amateur based. In essence, operate within your amateur authorizations - don't decide you "need it" just because you want it. Of course, you will learn that the rules mean something once you have been licensed more than a couple of years - the current examinations obviously don't stress that the rules trump any entitlement. 73, ...

Took a few calls but there's a new route driver for UPS and all seems okay now, though the UPS stuff does occasionally go to the PO to deliver and with the satellite mailbox setup here, that means a trip into town if the box is too big to fit in the small satellite box container.

As others have said, it is tough to obtain maximum efficiency - the two largest contributors to loss being resistance in the tuning capacitor and ground losses. A couple of wires soldered to the tabs of a receiving capacitor with a sliding contact to the rotor will have large losses and several commercial antennas are made this way. Since small loops use vertical polarization, unless you are over really good soil or sea water, they need to be high enough to minimize earth losses - typically 0.1 to 0.2 wavelengths. I modified a portable aluminum loop by enlarging it to 5-foot diameter and improving the capacitor arrangement. It worked acceptably well and I was able to make contacts on 20, 30 and 40 meters with a KX3 barefoot. However, I find that almost any full-size antenna works better and the difference is usually one to two S points. When operating portable, I now deploy a telescopic 40-foot fiberglass pole with a wire antenna - vertical or loop. I continue to use two small transmitting loops in my HOA restricted home shack.

Our building is on a street different from the street in the "street address" and not visible from it. Fortunately the courier service drivers know where the building is and where access to our unit is located. Any USPS delivery is to the "street box" on the "named street" and unless we check it daily - which is a pain - we don't know if anything has arrived that cannot be tracked online. Recently we had a contract-carrier delivery of a very expensive and bulky item, and in the delivery instructions we specified "call for directions". It worked like a charm, and the driver even stuck around while we unpacked the box and checked for damage, of which there was none. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From mzilmer at roadrunner.com Thu Apr 27 13:42:22 2017 From: mzilmer at roadrunner.com (Matt Zilmer) Date: Thu, 27 Apr 2017 10:42:22 -0700 Subject: [Elecraft] K3 P3 and KAT500 In-Reply-To: <745999907.6169441.1493311781609@mail.yahoo.com> References: <1493231045227-7629969.post@n2.nabble.com> <1493301060835-7630020.post@n2.nabble.com> <000001d2bf67$d77e48c0$867ada40$@nwlink.com> <1493309884442-7630032.post@n2.nabble.com> <745999907.6169441.1493311781609@mail.yahoo.com> Message-ID: <86071b89-a860-3e87-d8a7-fbfcf896dd40@roadrunner.com> BND MAP may be set to OFF for 10m on his K3.

There is a KDSP2 installed and I found an old post of yours referring to its potential to cause distortion and had therefore already turned NR off and set it to bypass. Alas, it made no difference to the characteristics of the problem. I have an old HP signal generator here but the problem seems so intermittent it's going to be challenging to get to the bottom if re-flowing the solder joints doesn't do the trick. I've been in my shack/office for a couple of hours now and the problem has come and gone more times than I can count. I am out on site (I'm a consultant biologist/ecologist and work some strange hours) over tonight and most of tomorrow but I should have some time over the weekend to at least make a start and will post again when I have made some progress - one way or another! 73 Denis MW0CBC / GW8OQV -----Original Message----- From: Don Wilhelm [mailto:donwilh at embarqmail.com] Sent: 26 April 2017 22:51 To: Denis Jackson; elecraft at mailman.qth.net Subject: Re: [Elecraft] K2 Distorted receive audio and low power output Denis, Do you have the KDSP2 installed in your K2? If so, check the DSP NR. If it is on, it can cause distortion. It does an effective job of reducing noise, but does introduce some distortion - and may appear intermittent depending on the signals and their level. If no KDSP2, then check the soldering in the PLL Reference area as well as the BFO area. Marginal solder connections may have been OK in the past, but can fail after time. Check the schematic for components in those areas and re-flow the soldering. You can also do the Receive Signal Tracing as indicated in the manual. You may have to connect a strong signal generator as described in the Troubleshooting section of the manual. An XG1 or XG2 will not provide a strong enough signal (the XG3 will), so construct the oscillator shown in the troubleshooting section of the manual. The power output problem may or may not be related. The best way to find the offending stage is to do Transmit Signal Tracing as described in the Troubleshooting manual appendix. When you get to a stage which produces less than the expected values, that is the output of the failing stage, and you can investigate that particular stage for the problem. Re-flowing the soldering may correct it. Component failure is not the most common cause of failure (soldering is), so do not jump to conclusions about a component being bad - exception is if one of the PA transistors has been damaged. If you find everything up to the PA transistor bases OK, then replacement of the PA transistors with the K2PAKIT from Elecraft may be in order. 73, Don W3FPR On 4/26/2017 5:19 PM, Denis Jackson wrote: > My K2 hasn't been used for a few years but, with the intention of > taking it out for a bit of SOTA work, I powered it up today.

I'm also using a KAT500 on each of my two K-lines in my SO2R station, and I too would appreciate a bit more "intelligence" in the KAT500. My fully automated antenna switching arrangement uses a microHAM Double Ten switch, with the control for the two radio ports coming from a Station Master on each radio, so there are only two feedlines that enter the radio room.The antenna switching hardware is concealed in the attic on the other side of the wall from the station. Like everyone else who has attempted to set up a SO2R station using multiband antennas, I've grappled with the problem that the design of all the currently available switching and control hardware explicitly assumes you have separate antennas for each band. For many of us, this just isn't true. I mainly use the KAT500 as a line flattener for my 160, 80 and 40 meter antennas; no problem there. But.. I also have a 20-15-10 dipole that I use for the second radio on the high bands. The dipole is pretty low and isn't particularly well matched, especially on 15 and 10. I now have the KAT500 on the secondary radio set up to match the dipole on 20 through 10. However, if I'm running SO2R with the primary radio on 40 and the secondary radio on 20 then I'll normally switch my SteppIR to the secondary radio, meaning I have to remember to put the KAT500 in bypass, and then to change it back later. Sometimes I don't. (Mother Nature and Father Time, you know.) Even in SO1R mode, I sometimes want to quickly switch to the dipole on the high bands if someone calls me well out of the beam's main lobe. The Station Master makes the actual switching very easy via a keypad on the desk, but in this case I end up with the radio looking into a fairly high VSWR antenna if I don't also manually put the KAT500 in bypass mode. This isn't so good, especially if I'm running the KPA500. What would be REALLY NICE would be if there were some way for the KAT500 to know which ANTENNA has been selected, and switch in the appropriate matching solution for that antenna on that band. I don't see any way to do this, given the present architecture. If there were some additional communication channel between the station control hardware and the KAT500 (and other Elecraft products) such as an extended command over the RS232 link in the case of the KAT500 or over the USB link for the KPA1500, conveying both band information and antenna ID could potentially be done. A simple 4 bit band code wouldn't be sufficient, but perhaps an 8 bit word with 4 bits of band information and 4 bits of antenna number would work. Of course, there then remains the not-so-small matter of formatting and transmitting this information packet from a wide variety of station control architectures using hardware from a number of vendors. Perhaps if Elecraft were to pave the way by implementing this capability the makers of the various commercial controllers would be willing to code in support for the feature.

There may be further economy as well as simplification to be had if this switching hardware is combined as a single product with the antenna selection switch (2 antennas out of 6 etc). While some may be happy running without tuner, many would want duplicated tuners external to the shared amplifier. Incorporating separate tuners would not impose additional RF switching requirements, but possibly some additional considerations relating to the control scheme. Of course, the user would want to be able to purchase the amp without built-in tuner. 73.

Expectations for a severe Cascadia earthquake include power outages for at least six months. Batteries and gasoline generators won?t last that long. That is a lot of amp to run off of solar. It needs roughly 1000 VA when transmitting. I would focus on easy to erect antennas with some gain. For your 10 meter net, a Moxon beam would give 3 to 4 dB gain, about half the the 7 dB gain from a 100 to 500 W increase. And it helps on receive, too, unlike an amp. Even with a mast or tower, it would be much, much cheaper than a KPA500. http://www.innovantennas.com/our-antennas/view/productdetails/virtuemart_product_id/455/virtuemart_category_id/4.html http://www.wb5cxc.com/10mmoxon.html I expect your local emcomm organizations already have frequency plans. From QRZ, it looks like you are in a valley, so you might plan for NVIS antennas. These are usually easy to put up, because they are low wire antennas. Another option would be a directional wire antenna. For example, if you are primarily communicating with Roseburg, then a 40m wire beam or ?ZL special? phased beam might work well. One bright spot about widespread power outages?you won?t have much RFI! That could allow working with much lower power than usual. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Apr 27, 2017, at 10:42 AM, Matt Zilmer wrote: > > BND MAP may be set to OFF for 10m on his K3.

I live probably 100 miles north of Harry, near Newport on the Oregon Coast. I have participated in a number of simulated emergency tests (SETs) anticipating the eventual Cascadia event with big earthquake and tsunami. First, I anticipate that everyone would be living in an RV/Trailer or out of a car because not many homes (or other structures) will survive a 9+ earthquake without serious damage, if they are left standing at all. So my SET operations are based on the assumption that energy will be precious. I have yet to run more than 100 watts into an end-fed wire strung between two trees. Often I ran only 20 watts with my K2. I have always been able to work over ranges of 50 to 1,000 miles using the best band for the time of day and sun cdx, especially if I revert to a digital mode. IMX voice traffic is tedious, slow and inefficient compared to just about any digital messaging system from CW to any of the more exotic modes now popular. I can sit at a table with various various incident commanders or team leaders using my keyboard to send traffic without interrupting their conversations. The one "frill" I like is a battery powered printer so that incoming traffic can be printed and handed over to the others there immediately. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Walter Underwood Sent: Thursday, April 27, 2017 1:09 PM To: Elecraft List Subject: Re: [Elecraft] K3 P3 and KAT500 I?m curious about running a 500 W amp on emergency power. Expectations for a severe Cascadia earthquake include power outages for at least six months. Batteries and gasoline generators won?t last that long. That is a lot of amp to run off of solar. It needs roughly 1000 VA when transmitting. I would focus on easy to erect antennas with some gain. For your 10 meter net, a Moxon beam would give 3 to 4 dB gain, about half the the 7 dB gain from a 100 to 500 W increase. And it helps on receive, too, unlike an amp. Even with a mast or tower, it would be much, much cheaper than a KPA500. http://www.innovantennas.com/our-antennas/view/productdetails/virtuemart_product_id/455/virtuemart_category_id/4.html http://www.wb5cxc.com/10mmoxon.html I expect your local emcomm organizations already have frequency plans. >From QRZ, it looks like you are in a valley, so you might plan for NVIS antennas. These are usually easy to put up, because they are low wire antennas. Another option would be a directional wire antenna. For example, if you are primarily communicating with Roseburg, then a 40m wire beam or ?ZL special? phased beam might work well. One bright spot about widespread power outages?you won?t have much RFI! That could allow working with much lower power than usual. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Apr 27, 2017, at 10:42 AM, Matt Zilmer wrote: > > BND MAP may be set to OFF for 10m on his K3.

Phone patch usage is minimal. Unfortunately the K3 is not highly recommended for MARS use as it does not have full power output from 2 to 30 Mhz. Low end radios from Icom, Kenwood, and Yaesu with TCXOs and full coverage from 2 to 30 Mhz are all that is needed. Encrypted digital and ALE are currently used as well as SSB voice. MARS has greatly evolved in the last few years and it is not what it was 40 or 50 years ago.

I've had good results using LMR400 (outer conductor) and an air dielectric tuning cap which will handle the 10-15W power of a KX3. In some informal testing comparing a 6 foot diameter loop and a 1/4 wave wire antenna (40 meters) using a car chassis as a counterpoise, the loop beat the wire by 5dB (NVIS path) (C/N on spectral display). How efficient is the loop? I don't know - not as efficient as a 4" diameter copper pipe 6 foot loop, but I do know it's relative ;) A mobile whip is *very* inefficient. The loop in this case is generally *less* inefficient :) You can make contacts on both. K4HKX did a very detailed comparison of loop antennas with full dipoles and other HF antennas. He posted his results here: qrz.com/db/k4hkx Very interesting read. I'm playing around with a mobile loop idea for 80 and 40 meters using the KX3. If it works as good as I think it will, it should give me about the same performance as adding a KXPA100 - or not... that's why playing with ham radio is fun. 73's Steve WD4SDC -- View this message in context: http://elecraft.365791.n2.nabble.com/Experiences-using-a-portable-HF-loop-tp7629785p7629840.html Sent from the Elecraft mailing list archive at Nabble.com.

The loop was WELDED to the stators of a butterfly capacitor -- that is a capacitor made with two stator sections and a common rotor. So there was NO sliding contact or other resistive pieces. It was fed by a small loop made of coax inside the larger loop with no physical connection to the main loop. It tuned from 14 to 30 MHz and would handle up to 100w. In horizontal configuration I found it just about as good a transmitting antenna as a full-size dipole, and (probably because of the perfect balance) quieter on receive. Of course the bandwidth without retuning was tiny (maybe 10 kHz on 20m) and the tuning was touchy. But it shows how good a loop can be if the design is optimal. 73, Victor, 4X6GP Rehovot, Israel Formerly K2VCO http://www.qsl.net/k2vco/ On 27 Apr 2017 19:13, michaelstringfellow wrote: > I have considerable experience with both commercial and home-brew loops. > > As others have said, it is tough to obtain maximum efficiency - the two > largest contributors to loss being resistance in the tuning capacitor and > ground losses.

So the smartest way to begin would be to order a KFL1-2 with the 30/40m option. Or should I go for 80/40? I have the 4 band module built in now with 40/30/20/15. The crystal will be custom ordered at www.krystaly.cz Email: krystaly at krystaly.cz KRYSTALY Hradec Kralove,a.s Ceska Republika. They make perfect quality for a very good pricing. Taking in account that my K1 VFO is 80 KHz wide and the allowed spectrum for 60m in DL is 15KHz ( 5.351.5 - 5.366.5 MHz in DL) I could split the left over 65 KHz into 2 parts and add these to the lowest and the highest frequency. 5.351.5 - 32,5 KHZ = 5.319 KHz -> This would be the lowest QRG. Adding 8 MHz on top we end up with 13.319 MHz. Do you think these specs here are fine for ordering the rock? Frequency: 13.319 MHz Package: HC-49, series resonance Adjustment: +/-5 ppm Stability: +/-10 ppm over OTR (-20/+70C) Well I just ordered some 13.300 MHz crystals for my NorCal SIERRA which I moved to that band. So I can use these ones too. Don, please let me know your thoughts?

If you want to put the band segment in the center of your K1 80kHz tuning range, your tuning would extend at 5.344kHz to 5.424kHz, so you would order a crystal at 13.344kHz. I believe the mixing scheme for the Sierra is about the same as the K1, but I don't know the VFO frequency low and high for the Sierra. I would order the 80/40 meter 2 band board - plus the 5 capacitors from the 30 meter RF bandpass filter (2 - 1800pF, 2 - 270pF, 1 - 4.7pF). That way you can have a 2 band board for 80 and 60 meters as well as the 4 band board. You will also need some capacitors to tune the 40m RF bandpass filters down to 60 meters - as I indicated, you will have to experiment to find the right values. The firmware for the K1 does not recognize the 60 meter band, but it does remember the CAL OPF offset for up to 6 bands. 4 are used for you 4 band board (do not duplicate any of those bands), so you could set the menu b1 for the 2 band board to 80 meters and the b2 to 17 meters.

That said, if you (or anyone else) wants to use a home-rolled or commercial rig/antenna switch, or an SO2R box, we?ll try to find a way to help with integration. For example, the KPA1500?s front-panel ?ANTENNA? switch has a tap function but not a hold function. We could create a hold function that would select between two rigs via an external relay. There are various possibilities for control that I?ll be happy to discuss with you if you?re interested. 73, Wayne N6KR > On Apr 28, 2017, at 6:45 AM, Thomas Donohue wrote: > > Hi to all: > > I'm changing the topic back to my original question, which has not been answered.

That said, if you (or anyone else) wants to use a home-rolled or commercial rig/antenna switch, or an SO2R box, we?ll try to find a way to help with integration. For example, the KPA1500?s front-panel ?ANTENNA? switch has a tap function but not a hold function. We could create a hold function that would select between two rigs via an external relay. There are various possibilities for control that I?ll be happy to discuss with you if you?re interested. 73, Wayne N6KR > On Apr 28, 2017, at 6:45 AM, Thomas Donohue wrote: > > Hi to all: > > I'm changing the topic back to my original question, which has not been answered.

Having two radio inputs on the KPA1500 or any amplifier, particularly if the RF exciter port selection is done either 1) automatically through RF Sensing or 2) remote selection would be a very cool feature for stations that are remote operated. I currently use the K3/KPA500/KAT500 remotely for the vast majority of my contacts because my primary residence is over 1,800 miles from my HF station. I also have a second radio (Flex 6000 series) that I?d love to be able to connect to a remotely controlled amplifier and be select as the input once SmartSDR v2.0 is released that will provide the ability the utilize the transceiver remotely. Currently, I don?t have an amplifier attached to the Flex that can be remoted, so my only option at the moment is to operate that transceiver ?barefoot?. I manage the K3 through a K3-Mini/0 with Remote Rig 1258, the KPA500 through the Remote Rig 1216H, and the rotor (Green Heron Controller) through a second Remote Rig 1216H. I have put down a deposit for the new PowerGenius-XL amplifier offered through FlexRadio Systems not because I plan to operate SO2R but because it will accept two exciter inputs, will allow remote configuration through LAN, and not cause problems for the amplifier. I currently have the ability to remotely select my antennas for the K3 and Flex using 403A?s Antenna Genius 8x2 antenna switch (it has a LAN connection) that I can control through my network connection to the shack. The Antenna Genius allows only one active RF input per antenna port, which provides some degree of protection to both transceivers. Thus, I will eventually have two radios both connected to the same amplifier operating as needed and then use the Antenna Genius to determine which radio is connected to which antenna (Dummy load/KT-36/End Fed Half Wave). Of course, this flexibility comes at a price? The Power Genius is significantly more expensive than the KPA1500 and uses a different architecture (e.g. two RF source inputs and two outputs to separate antenna ports which allows operation on two different bands with rapid band switching). Given Wayne?s comments below that there isn?t space to incorporate two RF inputs into the KPA1500, someone else may consider offering such a feature that could be integrated into the KPA1500 architecture. However, a 3rd party product adds to station complexity and space needed on the operating desk versus having it incorporated directly into a RF amplifier. Where high reliability is essential for remote operation where you know ?it works? and the status of which radio is actually operating through the amplifier is clearly delineated, I?d be more reluctant to depend upon a 3rd party ?add-on? versus having the capability built into the amplifier with the ability to properly monitor equipment status.

Isolation is greater than 100 dB between radios for any combination of selected antennas, WITH ALL OUTPUTS UNTERMINATED, and only the two radio ports terminated by the 50 ohm source and 50 ohm load of the VNWA. This is a worst case condition. Return loss is also quite low up to 6M. The switch offers many control options, from pulls to ground or to V+ or BCD to the far more sophisticated Antenna Genius controller, so it's sufficiently versatile that it can be used in almost any station. I'm controlling mine with the "pull to ground" control output of a 5B4AGN TXBPF filter set, which gets its input from the K3 AUX out band data. Which control logic for the 8x2 is selected by a DIP switch, and wiring is to a 15-pin DB connector. This is an excellent switch, and by far the best I've measured. As a point of reference, isolation for the Array Solutions 6x2 is about -55 dB, and return loss gets unpleasantly high above 15M. The 403A 6x2 is in the range of 75 dB isolation. I haven't measured any other switches. 73, Jim K9YC On Fri,4/28/2017 12:05 PM, Barry Baines wrote: > I currently have the ability to remotely select my antennas for the K3 and Flex using 403A?s Antenna Genius 8x2 antenna switch (it has a LAN connection) that I can control through my network connection to the shack.

With the growing popularity of remote operation, there's an opportunity for more than just one vendor to produce a line of Ethernet-controlled RF switches in various x(in) to y(out) matrix options. In this case, a 2x1 switch would serve the purpose without burdening the rest of us with a feature we may not want to pay in the KPA1500. N4CC and I share a remote site in north Florida, on the FL/GA state line. Our current HF amplifier has a built-in 4-port antenna switch. While we would like the KPA1500 to have 4, or even 6 output connectors, that convenience is probably best managed with an external RF switch that links to the KPA1500 (and/or K3) for automatic antenna selection on a per-band basis. Although we could likely use DDUtil or other such 3rd-party control programs, hopefully Elecraft will consider a line of external RF switches as an option with the amp.

Here's where we stand at the moment. I am certified ICS 100, ICS 100b, ICS 200, IS-00700a (NIMS), ICS 800B and others. Organizationally we are Red Cross, UVARC (Umpqua Valley Radio Club), Douglas County ARES on the local and State level. Our local are on top of our game. Our EOC is located in the Douglas County Sheriff's Office. (Lot's of hoops there- finger prints etc.) When we do sets it is with State emergency services, local hospitals, the VA medical center, SARS (Search and Rescue) etc. Geographically we are in the Cascadia Subduction Zone high impact area. Considerations are tsunami, quake, floods. The State of Oregon has provided tsunami and quake damage modeling data that is dialed into various possible Richter Scale scenarios. The big one is overdue by an estimated 50 years. Our very local scenario is filled with mountains and valleys. We are the land of ?One Hundred Valleys?. Actually there are thousands of them! 2M is very spotty. The USFS ( I have 80 acres in the middle of Umpqua National Forest ) radio infrastructure is miserable. Cut backs of appropriated $. We coordinate with County SARS. I am personally CERT certified. At one stage of my long life I was an EMT for some time. Solar, generator and grid. Our ARES group requires go bags for all vehicles. Few people but a lot of livestock and gardens here. My only concern was availability of frequency bandwidth. We have a least two Extra Class licenses in the community and one MARS certified. Unfortunately they are many 15+ miles away deep in a valley. We're trying. 73 Stan KG7FYI On 04/27/2017 08:08 AM, Marvin Wheeler [via Elecraft] wrote: > Eric: > > Speaking as a former professional Emergency Management Coordinator you > are > asking to be able to do something that will not endear you to neither the > County, State, or Federal Agencies. > > Having persons uninformed with net operations is totally disruptive to > the > point, at times, that all traffic stops.

What happens when you plug a straight key into the KEY jack and close the key? If the K3 goes into TX, then the K3 is OK, check your external keyer and its cable to the K3. Should you not have a hand key, just put a 1/4 inch phone plug into the jack and short between the tip and the sleeve. 73, Don W3FPR On 4/29/2017 2:43 PM, Mike Broga wrote: > I recently rearranged the shack and now my external keyer will not key the K3.

I assume you are using the CODEC in the K3S - if so, do you have anything plugged into the K3S LINE IN jack? That alone could be the problem - LINE IN overrides the line out audio from the CODEC. If the LINE IN jack is empty, then put the K3S into TX TEST mode (or connect a dummy load) so you do not emit any RF on the air. Check the MIC SEL menu to make sure it is set to LINE when if DATA A mode. Then set the soundcard LINE OUT level to about 75% in the computer. Put FLDIGI into transmit and adjust the Line In gain (MIC GAIN) to achieve 4 bars solid on the ALC meter with the 5th bar flashing. That is the proper audio level for soundcard digital modes - leave it set there. Go back to normal transmit and see if you have RF. Adjust the POWER knob for your desired power level. Ignore the info in the FLDIGI instructions which say to set the power at maximum and control the power level with the audio level. That is for other transceivers - for the K3/K3S, follow the instructions in the K3/K3S manual. 73, Don W3FPR On 4/29/2017 2:33 PM, Mark Simms wrote: > Can someone provide detailed set up parameters to get the K3s to work with > FLDIGI?

Are you saying that if you tap BAND (up), you move from 24 to 28.676 MHz and then can't dial VFO A down to 28.4? Explanation of why this is confusing / strange / whatever: VFO A is just an optical encoder with A/B outputs. A and B act in quadrature (only one of them changes per "click") and the transitions are counted by a microcontroller (MCU). The only limit on what frequency range you can dial to is the firmware inthe MCU. The K3 allows receive from VLF (136 KHz) through 30 MHz, used without a transverter. Why don't you try direct frequency entry before any next steps. See if you can enter 28.400 MHz. At least that will put you on freq. Then you can memorize it using the V > M switch. I wouldn't EE INIT the radio until all other options are exhausted. If you decide to do that anyway, be sure and save your K3's configuration first. You'll need to restore it after the "set defaults" is completed. 73, matt W6NIA On 4/29/2017 11:03 AM, KG7FYI wrote: > Thanks Matt. Nope all bands are set to In.

Power-up was normal, with the Forward Power LEDs, SWR LEDs, and Range LEDs properly flashing momentarily in sequence, then the 1.4 Range LED remains illuminated. 2. The calibration was normal. With power on the system, I adjusted the CAL potentiometer for 4.5 VDC between the ground test point and TP1. The only aspect of the checkout and calibration which was not normal was the resistance test across the battery holder terminal. With the power switch ON and no battery or DC power connected to the unit, the resistance should be > 1 megohm. With my DMM on 2M ohms selection, I receive a reading of 0.651, which is < 1 megohm. I confirmed the orientation, location and values of all components, confirmed the quality of solder joints, and verified that there are no bridges. Unless I missed something, the assembly is correct. Any thoughts on the resistance reading? Can I proceed with using the W1 or will this affect the accuracy of its operation? Thanks!

Check to be certain that the VFO Lock is not turned on. If the VFO A knob does not change the frequency, then VFO Lock is on. You should be able to tune from 28.000 MHz to 29.700 MHz with the VFO knob when the band is set for 10 meters. The K3 is not set to fixed frequencies by default. VFO A (or VFO B) should be able to tune the entire ham band. 73, Don W3FPR On 4/29/2017 2:03 PM, KG7FYI wrote: > Thanks Matt. Nope all bands are set to In.

Royal Robbins was 82. He joins another mentor who left us in 2012: Herb Conn. Between these two I learned how to climb and how to cave. I owe many of my wilderness ethics to them. While I never climbed the big walls of California nor spelunked the largest caverns of Kentucky I did climb in the Black Hills and at Devil's Lake in my home state of Wisconsin. Most of my caving was in the Hills under the Conns' tutelage. Royal taught me how to leave as few marks on the rock face as I did on the way to it. I do miss standing on a summit and lying under twenty foot long soda straws but miss them both even more. The sun has been active this week as the auroras show. I got two emails from my brother telling me the West Coast was booming into Wisconsin right around net time yesterday. He said the East Coast and EU were weak but everybody west of the Rockies was 30 over S9. Too bad I can't convince him to get his license again. However, this bodes well for at least the forty meter net. Hopefully, twenty meters will open up again too.

I just checked again, making sure I wasn't in contact with anything, and got the same result. I confirmed the accuracy of my DMM against several resisters from my spare parts inventory, and received accurate readings in the lower resistance ranges, but did not have anything in higher resistance, or enough smaller resisters to string together in series to verify the 2M range setting of the meter. It is a no-name meter I bought from a hardware store a few years ago, and I have a new one on my wish list. But at this point I have no evidence that this meter is inaccurate. Although I have not had the opportunity to connect the unit to an antenna system, the rest of the functionality tests out fine so far. Thanks!

You probably know this but NVIS would be a perfect solution for you. 40 meters would be the easiest NVIS antenna (very low dipole) to implement. "Military NVIS communications mostly take place on 2-4 MHz at night and on 5-7 MHz during daylight." Here's a link explaining: https://en.wikipedia.org/wiki/Near_vertical_incidence_skywave However this would require General Class licenses or higher for voice modes. 73 and Good Luck!

I can assure you it is not something I programmed into the system. I checked the config menu (BND MAP) and all bands are in. Somehow I may have unintentionally programmed an issue into the system. I haven't programmed anything into the system so resetting the defaults should be no loss if all goes well. The curiosity is how I got into this mix in the first place.

If not, you likely have the VFO locked - look for the little 'padlock' icon in the upper right corner of the display. Hold the LOCK button to the right of VFO A knob to toggle LOCK on and off.

Because most of the locals have CB radios it is how we communicate in an emergency. The local repeaters are dead other than during net times or drive times. If you really need help CB radio works much better than our amateur bands. We also use it to avoid the many log trucks. Please try NVIS on 40 or 80 meters. You'll find you can cover most of the state with its use. Plus the antennas can be ad hoc - tossed into trees or even an old fence line. 73 & GL, Kevin.

There's a bit of fiction in the belief that antennas must be very low for NVIS. Fact is that higher is better, up to a quarter wave. The optimum height for a horizontal antenna for NVIS is a quarter wave length, and performance declines only slightly (1 dB) up to 3/8 wavelength. High angle radiation for an antenna a quarter wave high is 4dB stronger than for one at one-tenth wavelength high. Thus, optimum heights are 30 ft for 40M, 60 ft for 80M, and high angle radiation is only 1dB down for 45 ft on 40M and 90 ft on 80M. http://k9yc.com/AntennaPlanning.pdf addresses this with a table and graphs. See Fig 36 and Table 1 on page 11. 73, Jim K9YC From jim at audiosystemsgroup.com Sun Apr 30 15:39:03 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sun, 30 Apr 2017 12:39:03 -0700 Subject: [Elecraft] K3 P3 and KAT500 In-Reply-To: References: <1493301060835-7630020.post@n2.nabble.com> <000001d2bf67$d77e48c0$867ada40$@nwlink.com> <1493309884442-7630032.post@n2.nabble.com> <745999907.6169441.1493311781609@mail.yahoo.com> <86071b89-a860-3e87-d8a7-fbfcf896dd40@roadrunner.com> <314ad4af-a8e3-7ff7-b1d1-7d224082a23d@surcp.org> <76a7c618-6f9f-060d-2b13-ea90f85a12e9@roadrunner.com> <0217A3FC-B601-4DEB-9F5C-5C66A6C25681@widomaker.com> Message-ID: <57043a53-27c3-68de-0217-ceeab556a29f@audiosystemsgroup.com> On Sun,4/30/2017 8:04 AM, KG7FYI wrote: > I have the second edition of Fred Cady's book.

While Fred's books provides a lot of good info in easy to read form, there's very little in that that can't be learned simply by studying the Elecraft User Manuals for your product. Note my use of the word "studying." This is necessary whether you're using Elecraft manuals (free) or Fred's (not free). Elecraft K3, K3S, KX2, and KX3 all offer a high degree of customization and many controls to fit the needs of individual users. The Elecraft manuals are pretty good at providing detail of how all those settings and controls work. When set up properly to match individual operating style and needs, it's rare to need to use a menu except to choose very different styles and needs. Taken together, the posts in this thread suggest a mental laziness about STUDYING the reference materials -- FCC Rules, equipment manuals, ARRL Handbook, ARRL Operating Manual, even the ARRL study guides for the license exams (and I mean the fundamental concepts, not just Q&A). Those of us who know what's going on and how things work have done that. It ain't that we're that much smarter, it's that we've paid our dues by studying. 73, Jim K9YC From john at kk9a.com Sun Apr 30 16:07:00 2017 From: john at kk9a.com (john at kk9a.com) Date: Sun, 30 Apr 2017 16:07:00 -0400 Subject: [Elecraft] K3 P3 and KAT500 Message-ID: <000001d2c1ed$5420a080$fc61e180$@com> The locked VFO has been suggested to KG7FYI numerous times as well as punching in the frequency directly.

If not, you likely have the VFO locked - look for the little 'padlock' icon in the upper right corner of the display. Hold the LOCK button to the right of VFO A knob to toggle LOCK on and off. What happens when you do a Direct Frequency Enter?

I think you are presumptuous to know my circumstance and make a judgment of my character based on a few simple questions posted on a email forum. Your analysis is full of snobbery and ill intent. It's really a turn off from someone who is trying to learn the radio, its operation and functions. I think your attitude and sense of internet etiquette needs adjustment if you don't mind me saying. I am choosing to learn this system at my own pace. I've built and configured the system just fine with this one defugalty. So back off.

Flying branches knock them down. But if the wires are still intact I can run the nets with the lowered antennas. Using less than optimal antennas works; just not as well as perfect antennas. In an emergency I really don't care about perfect performance, I simply want to contact someone for assistance. By all means put up the best antenna you can just remember any antenna can make contacts. Years ago I wrote some software to display antenna propagation patterns as a half wave dipole was lowered from 1 wavelength above ground until it was on the ground. The results were pretty interesting. By using the program I found many heights would work well depending on where I wanted to contact. At less than 1/10 wavelength above the ground the radiation patterns got rather odd but still worked for in-state comms. Once I had modeled what was going to happen I tested it by dropping my antennas to different heights and tested comms. Theory and practice correlated quite nicely. Kevin. KD5ONS P. S. The application also modeled 1/4 wave verticals and loop antennas. I never found the time to model the Yagi-Uda, the math got too hairy. Using Euler's equation a few times got me through the three antenna types I was able to model. Beating on the Bessel functions would have taken longer than the time I had allotted to me. K.

Of course, there are also times where folks bump heads by sheer accidental reasons... I'd like to think we have a case of the second type here... You've been provided excellent information, and some truthful expression of how you have "come across" to this group. Frankly, I remember thinking when I read his response to you: "He was a lot nicer than I would have been." I chose not to write a response so as not to appear "cantankerous", but I can't let this go. Trust me, Jim has no pride invested in this group... he's simply trying to help you. Being a butt-head BACK to him is incredibly disrespectful to a very nice man and an incredibly knowledgeable resource, and likely not your best course of action.

It sounds as if everyone is off frequency and no amount of tuning will clear it up. I was using 20 meter SB and it is the same on all other frequencies except 2 meter. I checked all settings that I use and nothing has changed. I had no problem the night before and problem was found on powering up the radio today. I also use KPA-500 and KTA-500 with this setup. I also checked and it is the same on both receivers. This unit was sent to Elecraft to be checked over and aligned about 3 months ago and has been working great.

So, while the pattern may show the main lobe straight up, the amount of RF lost in the earth below increases. EZNEC confirmed to me that about 0.2 wavelengths up is the optimum height for the strongest vertical lobe (NVIS pattern). That fits with the fact that 0.2 wavelength spacing between the driven element and reflector of a Yagi produces the maximum gain. Running a wire near the ground helps too, since the earth is, at best, a poor dielectric instead of an efficient reflector. Well supported towers have withstood some serious quakes, including our land-mobile repeater towers in the Loma Prieta earthquake that broke the S.F. Bay bridge and knocked down a good part of downtown Santa Cruz back in the 80's. However a tower, no matter how robust, is of little use if operations need to move elsewhere. They are darn clumsy to move by hand in an emergency. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of kevinr at coho.net Sent: Sunday, April 30, 2017 1:40 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] NVIS HF vs VHF line-of-sight & CB I lose my antennas about once each year to straight line winds.

Very high Coefficient of Aerial Aluminum on 7 or so towers, very low noise levels. I had been checking into the NorCal traffic net on 80 and wanted to continue. The main 80 meter antenna at W7RN is a near-full-size 3-el yagi at about 160 ft [~48 m]. It fires flames at Mongolia very nicely, however the NorCal stations at 80-150 mi [130-240 km] from me were around S5-S7. Here at home, we are members of an HOA, everyone can fill in the blanks from that. Just for grins, I installed an end-fed wire I got on-line on the wood fence. It runs on electric fence insulators and is about 6 ft [1.8 m] high, with a 90 deg bend about 1/3 of the way down. CA stations on 80 are 10 to 20 dB over S9 on it. I have discovered that it actually works way better than I expected for NA contacts, and hits KH6 pretty well on 20. I make a lot of Q's with it in the Wednesday CWOps Tests when I manage to get on. I won't make Honor Roll with it, but it is very surprising at 100 W from my K3. I bought another and will use it into a tree from Pershing County NV in the 7QP next weekend. Our fan dipoles in SE Asia were 20-30 ft high at most and worked just fine, even to the Philippines. For emergency uses, I'd worry less about the mathematics of antenna radiation and attempting to precisely optimize it, and much more about ease of installation and survivability. If it isn't buried and you can cram power into it [and Elecraft ATU's are very good at that], it will radiate. 73, Fred ("Skip") K6DGW Sparks NV USA Washoe County DM09dn On 4/30/2017 3:49 PM, Ron D'Eau Claire wrote: > Ground losses mount rapidly as a horizontal antenna is lowered closer to the > earth.

I was at Galena AFS at the time, on the Yukon River in the northern interior just south of the Arctic Circle. It's fairly flat up there and after we realized there was an earthquake, we could watch to the south and it appeared that there were ground waves moving rapidly toward us. It ultimately broke off the wooden flag pole in front of the chow hall. The WW2-era wooden hanger and control tower survived just fine, some bookcases toppled and spilled coffee was about all that happened. The reinforced concrete alert hangars ... not so well. Much of the damage in Anchorage was the result of liquification of the ancient stream bed beneath it. The effects of any given magnitude earthquake are almost completely determined by the conditions at any given place. We had a couple of not-high dipoles and one of those humongous LP arrays for the MARS station. ACS went down, our dipoles worked just fine. That LP monster is basically a poorly optimized 3 element yagi on any given frequency and didn't work all that well. Were I in the EMCOMM business and planning for a major widespread disaster situation, I'd focus on the physical aspects of the antennas ... transportability, survivability, ease of deployment, weight, and the like.

How many folks are prepared to actually do all the work necessary after a major disaster. The majority of folks would not be able to walk to the nearest shelter let alone help others. We, as a nation, are woefully under-prepared for disasters. The ECOM folks talk about it, plan for it, but don't train the public to be in better shape to handle any given disaster. While I have taught many ECOM classes I am never allowed to say more than a few words about fitness. I do it for rehab but it has helped me stay safe in the various unsafe times I have had up here in the wilderness. 73 & GL, Kevin.

Our club does annual field trips just for that purpose. To be honest I was shocked what a long wire could do with the right equipment. I'll the first to admit I'm just getting my legs. That said, radio is a fantastic tool for my needs. I've never done it as a hobby and always have had it as a community help tool or basic communication tool. I lived off the grid up in Montana for a decade and found radio a great way to keep sane. I had an old Kenwood TS-140s back then and spent a lot of time listening. I didn't have a license so never TX but I would have if I had to. I'm not an anarchist and totally respect the rules but life and limb take precedent over the rules in my world. I'm not even tempted to do anything but get stick to the plan. Maybe its my old Vietnam days but every option should be available. My mind set is such that I'm putting guy wires up on my free standing antenna. It can't hurt can it?

Without doing a detailed cost sheet of various options, I will just assume $10,000 for the configuration though it could be more than that. Is this affordable? To help answer my question, I did some research using both my ARRL book ?50 Years Of Amateur Radio? and the US government?s inflation index calculator. If you are not aware of this particular book, it describes a whole slew of different manufactured rigs from the 1930s through the 1980s with year of introduction and cost in US$ at introduction. Some examples: Collins KW-1 Transmitter, 1950, original cost: $3850, cost in 2017 dollars: $39,942 Hallicrafters SX-88 Receiver, 1954, original cost: $595, cost in 2017 dollars: $5393 Heathkit DX-100 Transmitter, 1955, original cost: $180, cost in 2017 dollars: $1644 Collins 30S-1 Linear Amplifier (1 KW), 1958, original cost: $1556, cost in 2017 dollars: $13,264 Collins KWS-1, 1955, original cost $1995, cost in 2017 dollars: $18,217 Collins KWM-2A Transceiver, 1961, original cost $1250, cost in 2017 dollars: $10,227 Drake TR-7 Transceiver, 1979, original cost (with some options) $1072, cost in 2017 dollars: $3827. So, a new technology K-Line is not that bad as something equivalent from Collins back in the 1950s could easily cost 4 times as much today! 73, phil, K7PEH From k2asp at kanafi.org Sun Apr 30 21:21:14 2017 From: k2asp at kanafi.org (Phil Kane) Date: Sun, 30 Apr 2017 18:21:14 -0700 Subject: [Elecraft] NVIS HF vs VHF line-of-sight & CB In-Reply-To: References: Message-ID: On 4/30/2017 1:22 PM, Bill Frantz wrote: > I have always wondered how towers hold up during earthquakes.

Even my consulting engineering company turns to those experts when doing stations that involve antenna tower survivability. 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon From donwilh at embarqmail.com Sun Apr 30 23:06:28 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Sun, 30 Apr 2017 23:06:28 -0400 Subject: [Elecraft] NVIS HF vs VHF line-of-sight & CB in 9.0 quakes In-Reply-To: References: <1493231045227-7629969.post@n2.nabble.com> <1493301060835-7630020.post@n2.nabble.com> <000001d2bf67$d77e48c0$867ada40$@nwlink.com> <8dd92046-5dcd-e625-ac53-474f70f2e8b2@surcp.org> <1493546643101-7630119.post@n2.nabble.com> <8b9851c8-245d-0c98-1a2f-02f394ee267b@surcp.org> <67e11e26-74b3-7368-9306-8850ace26411@coho.net> <807a9a15-0a54-f66a-42b2-cacd938de4e7@coho.net> Message-ID: Stan, While you have made your motives clear, if such an emergency does arise, just powering up radios and transmitting can result in communications chaos. I encourage you to get on the air not only to familiarize yourself with your equipment, but also to experiment with a variety of antennas that can be deployed easily - your home antennas will likely come down in such a disaster. Get involved with local ECOM organizations, and if they do not exist for you, form one. Ordered nets are the norm during emergencies, and someone has to act as net control - to whom all traffic is directed. Establish standard frequencies and practice, practice, practice so that all participating know the format and the rules of proper operating. You might want to consider taking an example (and perhaps some guidance) from the National Hurricane Net, which many of us are quite familiar with here on the East coast. In the event of a disaster in your area, you will likely be forced to use low power to conserve battery power and depend on relays from individuals who can run higher power outside the disaster area. You may have to learn to setup and use digital modes as well as voice in cooperation with your local and area Emergency Communications Center (ECO) which coordinate Police, Fire, Rescue, Hospitals and other emergency services during a disaster. That is all very organized communications. If you are concerned about a disaster, I recommend you become familiar with it and hold practice sessions communicating with other concerned hams. Many EOCs hold simulated emergency drills that you might want to participate in. ARRL Radio Amateur Field Day is a good exercise in setting up a functional station in a short order of time and operating on generators or other forms of emergency power. Communication of Health and Welfare information can occur on non-emergency frequencies in the ham bands, but that still needs to be done in an orderly fashion since those in the disaster area can be expected to be operating at low power and depending on relays from outside the area. There are formats for messages that operators should observe so the message gets to the intended recipient in an orderly fashion. The ARRL information is quite helpful for the formats and relay net operating procedures. What I am trying to say is that the formats and operating procedures for emergency communications is already in place, and you should become familiar with them and practice with your own local group and/or participate in national nets and exercises. 73, Don W3FPR On 4/30/2017 9:41 PM, KG7FYI wrote: I'd like to say > that radio is a hobby but the fact is that my only motive was that lives > are at stake.

Our HP building (now a Tesla building) on Deer Creek Road had hydrogen piping and HF Waste piping. That was fine, but a 4 main in the sprinkler system broke, soaking lab notebooks. I remember planning a route home to Mountain View that did not go under or over any bridges. I still had to deal with a water main break. And then there was Hurricane Betsy when I was growing up in Baton Rouge. No phone for 7 days and no power for 10 days. The toppled red oak in the back yard was the best tree fort ever.

To my mind, that skill may be critical in an emergency. and with the proliferation (and acceptance) of ready made manufactured antennas, I am afraid that skill is decreasing in ham radio circles. Yes, it does take a bit of studying and experimenting, but is not really that difficult. If you can do simple multiplication and division, you can calculate the length of a halfwave antenna that can be used for effective communications - all it takes is some wire and a feedline. 73, Don W3FPR --------------------------------------------------------------------- Stan, While you have made your motives clear, if such an emergency does arise, just powering up radios and transmitting can result in communications chaos.
