If the K3/Orion transmitters had significantly more spurious tx products than the Flex transmitters, that could also explain why the Flex receivers seemed impaired compared to the K3/Orion.

Now you've brought in other data to support the conclusion ;-) The Flex ops should have dialed in a little front-end attenuation to alleviate the ADC overload problem. The K3 and Orion do that automatically ("hardware AGC") to avoid ADC overload.

Yes, ARRL Labs tests are damning, though you would never realize it if you only read the text. When is ARRL going to assign technically competent authors to these reviews? That said, Flex did issue firmware/software that is said to reduce keying sidebands.

Part of emergency preparedness is understanding various rigs non-prejudicially for their various strengths and weaknesses and choosing rigs for strengths and avoiding rigs for weakness as those apply to the specifics of an application. These days weak signals and close multiple transceivers call for the likes of K3's. At N4C field day we frequently had a CW station and SSB station on the same band with no interference, and actually without being aware of each other. No noise, no anything. I know what a K3's hardware AGC kick-in sounds like and that was also absent. This has been our experience for five or six field days now, and together with the small light size and portability, makes the K3 a top pick for FD. Not because of Koolaid, but because of proven suitability to the application. I'm waiting to hear about KX3's for FD, especially battery operation, long a specific niche for K2's. We did not have a K3S or K3 with KSYN3A for evaluation. We have a standing question of whether K3S/upgraded K3, with some horizontal separation, will be able to operate a few KHz away from each other on the same band/mode segment, e.g. the 40 CW station, and the GOTA station on 40 CW at the same time. Perhaps next year we will find out. N4C operated at the Grey Goose Farm near Creedmore, NC. The group was a large portion of the North Carolina East chapter of the Potomac Valley Radio Club. This group contains a significant supply of K3 owners, who regularly bring K3's to FD and multi-op contest events. For them portability and immunity to high RF environments are top-of-the-list reasons for purchasing K3's as opposed to other choices, easily serving FD style applications. At NY4A, also primarily manned by PVRC NC East members, going back pre-K3 the FT1000MP was the main rig, which had gradually replaced all the stalwart Japanese rigs of prior years. For some time the MP was the only rig seen there. When the K3's and other rigs with new generation RX came out, and the differences became known, The MP's were gradually replaced. A tally of the list of MP owning operators who had manned NY4A at some point indicated that 11 MP's had been replaced by 14 K3's and one Orion. Of that group, no one owns a Flex to this date. But neither would I consider any of them to be a "Flex-basher". I do know Flex owners, single home stations, who get outstanding performance away from high-RF multi-TX operations. Various problems with CW and spectral purity seem to be a continuing manufacturer's emphasis for solution. They're out there on a particular bleeding edge, with a particular emphasis, with its own set of problems. We'll just see what they do. Bashing not necessary. UPS currently has my 2015 K3 upgrade round: KXV3B, KSYN3A's, a second KBPF3 (A version) and finally a P3 and P3SVGA. I will get the new audio board when it's available.

I do appreciate the League trying to keep costs down but sometimes you get what you pay for. Years ago I wrote the author of a QST published construction article pointing out an error. He sent me his original schematic. QST had redrawn his schematic using multiple ground busses using the pitchfork ground symbol and thereby combining busses. I wrote the editor explaining these errors were doubly wrong since the EU bands the use of the pitchfork symbol for any use other than a safety ground (green wire terminals). I got a reply ignoring the fact the circuit was changed and stating they didn't follow European standards. In fact they made their own standards. How about adopting IEEE or some other standard electronic symbols? If they are going to make their own standards then, they should not be in contravention of existing standards. For instance QST frequently draws a differential amplifier as an op amp. Granted the same ICs can be used for either an op amp or a differential amplifier but use determines the proper symbol and rarely are op amps (analog computing) used in ham radio. Other inconsistences abound like using both square and triangles to represent a linear voltage regulator. Make up your mind and stick to it.

I aimed my yagi directly at the house, which are separated by approximately 40'. The 24960 signal was around S5-6. I wrapped 9 turns of the LAN cable going to my old XP computer around a 2.4" #31 core. The signal dropped to S0 - still lightly audible. The one at 24900 was completely gone. The 6m ones also dropped to the S0 - lightly audible. I have more cores, but my other LAN cable going to my newer Win7 machine is too short to wind any turns around the core. Disconnecting power to the wireless router completely removes all spurious signals on 6m. So, I know I can make improvements, but for now it is livable. The home theatre system audio problem was totally fixed. The right surround channel was totally overloaded by anything more than 150w on 20m. Because the connectors on the audio cable would take time to remove, I wrapped 9 turns around the 'Biggest #31 clamp on'. No trace of interference at 600w. So, a big thank to Jim, K9YC, for his tutorial (and experiments) on curing RFI.

Their redrawing a perfect example of the muddy thinking about signal common (what we call "ground" in a circuit). In his EMC classes, guru Henry Ott, WA2IRQ, emphasizes the importance of knowing where the return current is flowing -- he talks about the hidden schematic concealed by the ground symbol. 73, Jim K9YC From wes at triconet.org Wed Jul 1 18:31:23 2015 From: wes at triconet.org (Wes (N7WS)) Date: Wed, 01 Jul 2015 15:31:23 -0700 Subject: [Elecraft] Help identifying this RFI Message-ID: <55946A3B.5030205@triconet.org> I've uploaded some videos to YouTube that show the problem I'm having.

It sure sounds like impulse noise, but other RFI professionals on the list may correct me. In general, impulse noise is best chased with an AM detector and the highest possible RX frequency. I have three tools that I can use this way. Most useful are a Kenwood TH-F6A talkie and a Kenwood VHF/UHF FM, both of which can be programmed for AM and have good sensitivity up to about 500 MHz. Both are programmed with presets of 160 MHz, 300 MHz, 400 MHz, and 526 MHz (the latter because that's the highest frequency before sensitivity falls off). To get close, I drive around listening to 160 MHz, then as the noise gets louder go to the higher frequencies. When I'm close enough to hear it on that 526 MHz memory, I get out of the car and switch to the talkie. With the talkie, a trick I learned from our Chicago fox-hunting guys. A talkie with a duck can be made directional by holding close against your chest, and sensitivity can be reduced by removing the duck. I once won a 2M fox hunt using only that talkie. The third tool is a Tecsun RX that tunes the AM aircraft band that's above the FM broadcast band. Obviously, the other tools are better, but I'm a "use the tools you have" sort of guy. :) 73, Jim K9YC From ei6iz.brendan at gmail.com Wed Jul 1 18:56:48 2015 From: ei6iz.brendan at gmail.com (Brendan Minish) Date: Wed, 01 Jul 2015 23:56:48 +0100 Subject: [Elecraft] Help identifying this RFI In-Reply-To: <55946A3B.5030205@triconet.org> References: <55946A3B.5030205@triconet.org> Message-ID: <1435791408.3977.14.camel@gmail.com> This sounds like power-line noise the trick to locating it is to work upwards in frequency as you close in on the source, I have had great success in locating power-line noise by closing in on it on 6M in my van then finding it on 2m as you get closer then finally on 70Cm For 2M/7Cm I use either an FT817 in AM mode or my VX7r Hand-held in AM with an arrow 2m/70Cm hand-held Yagi Use logic and method to close in on the source and don't make any assumptions about the faulty hardware on the power company side. For example some Hams have in the past (after locating the approx location) told the power company that it's a 'faulty transformer' Replacing the transformer has in some cases resolved the issue BUT only because the replacement process meant that all the loose hardware is now done up nice and tight.. By the time you get to 70Cm you will be very close to the source and can probably narrow it down to a pole with a small directional antenna Some may suggest hitting the suspect pole with a big hammer, Don't do that! It's dangerous (faulty hardware may result in the line falling ) and it's imprecise the ARRL have some very good info on location powerline noise and the causes which may help your CO-Op 'rooke' better understand the issues Here http://www.arrl.org/power-line And particularly here http://www.arrl.org/power-line-noise-mitigation-handbook-for-naval-and -other-receiving-sites The better job we do on narrowing down issues leads to better relations with the power company. In a few cases here In Ireland we have been the early warning system for things that were potentially dangerous faults and as a result we now have a good working relationship with the Irish power utility Hope this helps 73 Brendan EI6IZ On Wed, 2015-07-01 at 15:31 -0700, Wes (N7WS) wrote: > I've uploaded some videos to YouTube that show the problem I'm > having.

Sunday started slow but about 0900L the band exploded with activity and remained that way until Field Day ended. I ended up with 154 contacts...a new station record for me. It was so amazing to see the band with the PX3. Sometimes almost hypnotizing watching the ebb and flow on the waterfall!

I'll try to address all of them in one message. First, I agree that this sounds like a powerline problem. I've seen many of them in my 57 years of hamming. What makes this different, and the reason for my call for advice, is the periodic nature of the problem. Actually, the problem is nearly continuous but is interrupted periodically. When I first started paying attention to this, I saw that the quiet periods were spaced about six minutes apart. This led me to think there is a timer involved. Grow lamps sprung to mind, since the "wild west" nature of this area makes that a distinct possibility. That said, my understanding is that these are on for much longer times. Regrettably, it's also our time for thunderstorms so my antennas are often disconnected so a good timeline is problematic. I do believe after some more listening that the periodicity is less uniform than previously believed. Maybe it's totally random. Some more data points: 1) I have opened the main breaker to my house and run the K3/Laptop on battery power with no change. 2) To the best of my knowledge there are no electric fences here. 3) My immediate neighbor to the north happens to be a welder, but he's not the culprit. He's put his wife to work and he plays. 4) The power feed to my house is underground. The nearest power pole is ~450 feet away from my tower to my WSW. The power line runs N and S from that point with another line intersecting at that pole and running to the west. 5) To my north there are two E-W feeder lines tapped into the N-S line. 6) One supplies my immediate neighbor to the north (the welder) via a pole mounted transformer. This is 350 feet due north of my tower. I've strummed the guy wires to these poles without noting any change. 7) A second 1000 ft E-W line feeds another transformer that is 850 feet NE of me. This transformer appears to have some oil leakage, but shaking the H out of it via the guy wires makes no change. The power company guys say it's OK. 8) Although we are entering our Arizona summer "rainy season", to date I've recorded a couple of hundredths of an inch. The noise issue predates this. Our power poles never swell, they just get skinnier and skinner. Years ago the power company tried to fix some noise problems I was having by replacing the plain staples that attach the ground wires to the poles with barbed staples that wouldn't (so they thought) pull out.

If you are 100% sure the leaking pole pig is not the problem, then search elsewhere. At a club station in Illinois, the pole pig was intermittent. Power company did not believe it, as it was intermittent. One evening during club meeting (alcohol was involved) a 30-06 made the pole peg 100% defective. Power company replaced it, and the noise was gone ever since.

I'll try to address all of them in one message. First, I agree that this sounds like a powerline problem. I've seen many of them in my 57 years of hamming. What makes this different, and the reason for my call for advice, is the periodic nature of the problem. Actually, the problem is nearly continuous but is interrupted periodically. When I first started paying attention to this, I saw that the quiet periods were spaced about six minutes apart. This led me to think there is a timer involved. Grow lamps sprung to mind, since the "wild west" nature of this area makes that a distinct possibility. That said, my understanding is that these are on for much longer times. Regrettably, it's also our time for thunderstorms so my antennas are often disconnected so a good timeline is problematic. I do believe after some more listening that the periodicity is less uniform than previously believed. Maybe it's totally random. Some more data points: 1) I have opened the main breaker to my house and run the K3/Laptop on battery power with no change. 2) To the best of my knowledge there are no electric fences here. 3) My immediate neighbor to the north happens to be a welder, but he's not the culprit. He's put his wife to work and he plays. 4) The power feed to my house is underground. The nearest power pole is ~450 feet away from my tower to my WSW. The power line runs N and S from that point with another line intersecting at that pole and running to the west. 5) To my north there are two E-W feeder lines tapped into the N-S line. 6) One supplies my immediate neighbor to the north (the welder) via a pole mounted transformer. This is 350 feet due north of my tower. I've strummed the guy wires to these poles without noting any change. 7) A second 1000 ft E-W line feeds another transformer that is 850 feet NE of me. This transformer appears to have some oil leakage, but shaking the H out of it via the guy wires makes no change. The power company guys say it's OK. 8) Although we are entering our Arizona summer "rainy season", to date I've recorded a couple of hundredths of an inch. The noise issue predates this. Our power poles never swell, they just get skinnier and skinner. Years ago the power company tried to fix some noise problems I was having by replacing the plain staples that attach the ground wires to the poles with barbed staples that wouldn't (so they thought) pull out. Furthermore, the staples were copper plated and the ground wires are aluminum. Eventually, the copper went away and now the staples are rusted steel. 9) My "sniffing receiver" is limited to 30 MHz but I have a lead to someone with more appropriate equipment, as well as expertise. 10) The Elecrafter's will understand this, I have a new K3S almost ready for delivery (credit card's been charged) it would be nice to be able to hear something on it.

It is normal for a direct conversion receiver to leak the LO at the operating frequency. The KX3 has a special preamp that prevents that. Also, antennas 20 feet apart might as well have coax directly from the transmitter into the receiver. That will cause huge coupling of TX into RX. Running 500W and 1.5kW? You are lucky that the receivers survived, let alone were able to work any band when the other one was transmitting.

Maybe it was something with the setup. Your expectations are unreasonable -- 20 ft is WAY too close, even for two great rigs on the same band at 500W. We run K3s to KPA500s on the same band for CQP (Cal QSO Party) county expeditions and use 250 ft spacing with antennas carefully located to be essentially colinear. 150 ft is not enough. 73, Jim K9YC From xdavid at cis-broadband.com Thu Jul 2 03:46:04 2015 From: xdavid at cis-broadband.com (David Gilbert) Date: Thu, 02 Jul 2015 00:46:04 -0700 Subject: [Elecraft] K3 FD report in high RF (K3 vs Flex 6xxx) In-Reply-To: References: <1670402772.783363.1435811587955.JavaMail.yahoo@mail.yahoo.com> Message-ID: <5594EC3C.8000103@cis-broadband.com> "Maybe it was something with the setup." That's an understatement. Running kilowatt-level power on the same band to two antennas only 20 feet apart is simply crazy.

It makes sense for one to provide data that can also be used when you need accurate time. They can also make for extremely accurate frequency sources for Elecraft radios that accept 10MHz reference signals from an external source. -- Cheers!

I made some measurements at my home station with two K3s on ten meters feeding different antennas. The antennas were 300 ft apart. I aligned the two yagis to face each other and saw only 17 dB of isolation. One of my K3's was hooked to a 1500 watt amp. With the antennas aimed at each other, there would be 30 watts coming down the feedline of K3 #2! Now my yagis were bigger than 3 elements: I had 5 and 6 element HB beams, but the problem is lack of isolation between any directional antenna. A few dB makes little difference. I still have not solved the in band overload problem entirely. 1500 watts is a lot of power. Cross polarization is a good way to go. Make one antenna vertically polarized and pick up a bit over 20 dB. The other technique is to avoid aiming antennas in directions that aggravate the problem. I think you would want 60 dB of rig to rig isolation with a legal limit amplifier for really good results. Having antennas at differing heights, cross polarized, and widely separated, can get you close, but I am afraid that boresighted antennas will still cause problems at 1500 watts. QRP looks better and better!!

The output of this element does indeed seem slightly low (compared with HC-4) but if you close-talk it (it's a boom mike after all) and use a gain setting of about 40 (out of 60) I find there is enough to get 6 bars ALC on voice peaks. There is lots of low-end response, so you will want to play with the equalizer to get either rag chew or dx-test response. It would be nice if the K3 had about 3 dB more audio gain ... the manual says that if I tap [3] in the mic select menu there should be more gain.

One more story that may be of benefit. But the summary is that such noise may be caused by a source on one of may drops from this branch circuit you're on. The source may even be on another distribution circuit, though I don't think this is likely. I had a timed problem like yours. Every day at 5PM +/- a few minutes, S9+20 dB arc noise would show up on 40 and 80m. Since I had a MARS net above 80m, I couldn't really do much with that noise level present. I scheduled one of the SCE (Edison) power quality staff to come out and see if it was something SCE could fix. Skipping several of his visits, he found an old 240 - 480 transformer that was on a daily timer. There *had* been a pump on its output but that was long gone and the output was arcing over at the secondary cabling. There is just enough ex-citrus land around here to have a few ages-old pieces of junk electrical equipment like that. The SCE guy disconnected the primary and the problem went away forever. In a staight line, this transformer problem was almost 1/2 mile away, and not even on the same distribution circuit we're on here. 73, matt W6NIA On Wed, 1 Jul 2015 21:19:05 -0700, you wrote: >Ref #7.

This will not be a firmware issue. The RF and AF gain controls are dual potentiometers. A standard voltage is placed across the pot (the two ends of the resistance stripe) and the wiper voltage is connected to an analog-to-digital converter. The digital output is sent over a multiplexed digital line to the CPU. The trouble you quote is not likely to go away, because it probably occurs from a cracked resistance stripe and/or a bent wiper, usually caused by a blow to the potentiometer knob(s). You will need to replace the pot, or have it replaced by Elecraft. This is not one of those eensy-teensy, fly-spec SMT repairs, you can actually see everything without a magnifying glass. Most people handy at soldering small electronic parts can do this repair, though it does involve a lot of disassembly to remove the forward board from the case front panel to expose everything. Contact Elecraft for a how-to conversation, a decision, and a replacement component or an RMA to repair. 73, Guy K2AV On Thu, Jul 2, 2015 at 2:06 PM, K4ia via Elecraft wrote: > The RF Gain control on the Sub RX acts weird.

Many newer monitors have multiple inputs -- Costco has been selling a 23-in Samsung that is nominally 14VDC but runs fine on 12VDC, draws less than 1A. It has one SVGA input and two HDMI inputs. I paid $170 plus tax. If your computer has no HDMI out, you can probably find an SVGA to HDMI converter. 73, Jim K9YC From k2mk at comcast.net Fri Jul 3 08:13:32 2015 From: k2mk at comcast.net (Mike K2MK) Date: Fri, 3 Jul 2015 05:13:32 -0700 (MST) Subject: [Elecraft] Monitor switching between P3 SVGA output and second output from main computer In-Reply-To: <314230004.35143383.1435904405935.JavaMail.zimbra@cableone.net> References: <314230004.35143383.1435904405935.JavaMail.zimbra@cableone.net> Message-ID: <1435925612998-7604547.post@n2.nabble.com> Hi Ray, It sounds like your primary monitor has dual inputs and your secondary monitor only has an SVGA input. You could consider switching monitor positions. If this is not acceptable due to monitor size or quality then an SVGA cable AB box should work perfectly.

I was at a FD site where we had significant interstation interference, and I think it was a combination of just too close and a dirty transmitter (IC7200), with the other station being a K3 with new synths. We didn't measure the antenna coupling, and I made a mental note to do that next time. What we had was 40m 2-el wire beam 20/15/10 wire beam G5RV The two beams had ends separated by only a few meters, but were almost collinear. The G5RV was parallel (in a bad way) about 30m away, but on the back side of the beams. Our troubles seemed worst on 20m. I know the spacing is not reasonable; past FDs at the same site/club had used KX3s or K2s QRP, and things were mostly ok then. So, I wonder: When you used the 250 ft spacing (and in the nulls), what kind of measured coupling did you see? What would people expect for power loss between the G5RV and the beam? Based on other comments, distance, and the beam heading the wrong way, I'd guess about 50 dB. I guess another question is, given a pair of K3-newsynth transceivers, what level of antenna isolation is necessary to bring the wideband noise from reciprocal mixing and transmit noise down to say the S1 level? Assume S1 is -121 dBm (from -73 and 8 units). Or really lets say that's the level we care about. TX at 100W is +50 dBm. If one uses -128 dBC for transmit noise, and assumes some improvement from the 108 dB of RMDR (taking the average of ARRL/sherweng) at perhaps 118 dB, then we need 53 dB of isolation. The IC-7200 has transmit noise at -94 dBC, so I'd expect 24 dB worse, which is S5 noise instead of S1 imposed on a perfect other receiver. I am curious if my math is confused, and how real measurements and experiences compare. It seems that reviews should set up 2 of the radio under test with controlled isolation and see how in-band artifacts are. And also test against a K3s both ways. 73 de n1dam From lists at subich.com Fri Jul 3 10:20:37 2015 From: lists at subich.com (Joe Subich, W4TV) Date: Fri, 3 Jul 2015 10:20:37 -0400 Subject: [Elecraft] K3 FD report in high RF (K3 vs Flex 6xxx) In-Reply-To: References: <1670402772.783363.1435811587955.JavaMail.yahoo@mail.yahoo.com> <5594D73D.1040103@audiosystemsgroup.com> Message-ID: <55969A35.6060506@subich.com> > What would people expect for power loss between the G5RV and the > beam?

The equation for free space path loss (coupling between antennas) is -40 dB + antenna gain - a wavelength dependent factor. However, that only holds in the far field (30m is near field for anything below 144 MHz). My hunch is that the isolation between two resonant antennas in the near field will be something less than 30 dB unless they are [reasonably] collinear. 73, ...

We never measured anything. Rather, we followed "good engineering practice," worked to find locations on our site where the antennas could be colinear and in each others nulls, and as widely separated as practical. We used resonant dipoles for 80 and 40, tribanders for 20-10. All had serious ferrite chokes at their feedpoint, all were fed with big coax (RG213, RG11), all Amphenol connectors, carefully tightened. Rigs were K3s with KPA500 amps. We also use bandpass filters on each rig, which helps with harmonics. The result was that we could have both CW and SSB on the same band. > What would people expect for power loss between the G5RV and the beam? > Based on other comments, distance, and the beam heading the wrong way, > I'd guess about 50 dB. First, dump the G5RV and use resonant dipoles with serious ferrite chokes. The chokes are probably good for 3-6 dB additional isolation, maybe more. Without them, common mode radiation from the feedline fills in the nulls of the pattern. Second, pay careful attention to all the little stuff, like the quality of the coax and the connectors, any switches that are in the way. When you're trying to get 50 dB down, that little stuff can make or break you. Note that our high power operation was for the California QSO Party. I don't consider FD a high power contest -- I've never run more than 100W, and for the last five years I've been doing it QRP. 73, Jim K9YC From jack.f6ajw at gmail.com Fri Jul 3 13:37:52 2015 From: jack.f6ajw at gmail.com (Jack F6AJW) Date: Fri, 3 Jul 2015 19:37:52 +0200 Subject: [Elecraft] KX3 2m: how to get +TX voltage during transmission?

A way for operator and logger to speak to each other over the headsets, as well as listen to the QSOs. Hearing both sides of the QSO was accomplished by using the monitor feature on the K3. However, the operator and logger wanted to communicate with each other sometimes as well. I added an external mixer to allow TX monitor and RX audio to be sent to a video stream as well as the headset for the logger. Combining mic audio from two headsets might be a little more complicated, especially to be active during RX as well as TX. David M.

My first reaction was to assume the antenna, an 80m horizontal loop, was the problem, but I am now convinced otherwise. To prove that, I did the following: - took the antenna down, refurbished it, and replaced the feed line (not wasted energy); - tried other baluns; - confirmed that my LDG tuner has no problem tuning; and - tuned it manually with the K3 tuner. The problem behavior is this. On 40m and 80m, the K3 will not find a decent SWR (<1.7:1) when auto-tuning. On 80m it has done fine tuning one direction across the band and failed going the other direction over a significant portion of the band. This is repeatable. On 40m, the SWR for the antenna system at the rig end is only about 1.7:1 at the low end and 1.4 at the high end. At the low end, the K3 tuner will not find a match under when the ATU TUNE button is used, except in particular circumstances. Using the menu system to check tuner values, it ends up with the capacitor connected at the antenna side at a low value and with a low value of series inductance. Effectively this is near the bypass mode. Hitting the ATU TUNE button to cause a long tune cycle makes no difference. Manually, the capacitor can be switched to the transmitter side, and a match near 1:1 is easily set by adjusting L and C. Today I cleared the memory on 40m and manually tuned at a low frequency in the band. Then, moving up the band at 2KHz intervals, the auto tuner was able to quickly fine tune the match and a full set of memories was created. This means that I can work 40m without a problem without hitting the ATU TUNE button, but if the ATU TUNE button is hit after a significant frequency change, the match is lost. Therefore, the key problem with the auto-tuner behavior is that when ATU TUNE is used in a case where there is no nearby memory, or a large frequency change has been made since the last transmission, the tuning algorithm apparently does not try switching the capacitor from the antenna side to the transmitter side, and the tuner does not thoroughly look for a match. Is this abnormal behavior for my unit, or is this a quirk of the system?

Tuners of all types do not work well into very low impedance loads. Add or subtract somewhere between 1/8 and 1/4 wavelength of feedline at the problem frequencies and see if that helps your problem. Of course, that solution possibly could introduce problems on other bands, but it is worth a try. 73, Don W3FPR On 7/3/2015 2:29 PM, Rob KK4R wrote: > I have been having problems with my K3 auto tuner using an antenna that has > worked well and been tuning easily for nearly all bands.

Probably the best is the YCCC SO2R Box. It's a club project, sold as a kit. Reasonably easy to build, lots of soldering, but no SMT. 5-6 hours by the time you make the cables.

I first started on field day as 3rd check-logger at the age of 10. A loudspeaker had to be on so we could all hear incoming traffic and that meant that visitors could hear and appreciate what was going on with all this activity. Nowadays, the lone operator has his back to visitors who have to keep quiet and all they see is a complicated rolling screen(s) of characters. I wouldn't go back, but I feel some fun for the rest of the team has diminished somewhat. 3rd check-logger also made the tea on the Primus stove. We were limited to 10W input in those days and nobody had heard of "emc." 73 David G3UNA ----- Original Message ----- From: "Walter Underwood" To: "Elecraft Reflector" Sent: Saturday, July 04, 2015 5:48 AM Subject: Re: [Elecraft] Paper Logs (was Audio mixers) Paper logging is pretty common for emergency communications.

Hardware requirements are driven by several things. I was lucky and found a nice used Microham micro keyer 2r+ for less than half of new. I really like it as it's very powerful (and trust me I am no expert on the subject, I'm still learning). The SO2R box was the easy decision. The biggest challenge for me is antenna switching. I run tribanders for 10,15 and 20 so I needed a good filter/triplexer setup. I ended up going with a full set of high power 403A filters and the triplexer. I used the high power filters as I wanted the filters on the amplifier output. For antenna switching I'm using a hamation 2x8 switch and integrated controllers. If your running monoband antennas you could use 200 watt filters between the K3 and amplifier with out the need for the triplexer.

The alternative is a 4O3A filter just for the tribander to provide a separate feed for each band and a set of monoband low power filters (e.g., the 5B4AGN kits) between the exciters and amplifiers. There are multiple options for SO2R controllers - you need to be able to switch a single set of headphones, mic, PTT, CW and potentially FSK between the two rigs. On the "simple end" is the microHAM micro2R, or TopTen DXDoubler ,the YCCC box is middle of the road, and the microHAM MK2R+ is the "high end" with built-in sound cards and basic station automation functions. 73, ...

Given the design flaws in Signalink USB, a basic TI USB CODEC which is used by most inbuilt USB sound implementations should have a noise floor six to ten dB lower than the Signalink. If the "sky noise" is set 10 to 20 dB above the noise floor of the CODEC implementation, you should see JT65 decodes very close theoretical -24 dB 50% threshold while JT9 decodes should be about two to three dB better (-26 dB) at the 50% threshold. Most Signalink units can be improved at least 6 dB by improving the noise bypassing (decoupling) on the 5V bus within the unit, adding proper filtering to the USB 5V input, and replacing the voltage divider used as a reference for the CODEC and audio op-amps with a low noise 2.3 V regulator. Signalink's transmit quality can be improved to a significant degree by turning down the CODEC output (Windows "slider") to prevent distortion in the CODEC and clipping in the op-amps then use an external PTT signal. 73, ...

Before computers were invented, you kept a chronological log, and a manual dupe sheet with 10 columns numbered 0 thru 9 into which you wrote the suffix of each call worked in the appropriate column. In those days, there were vastly fewer prefixes than we have today, and the suffix was sufficient to determine that the guy you were listening to was not a dupe. in the later 70's, my non-ham neighbor wanted to see what FD was all about so he became my logger on CW. I showed him the numbers and the class letters [there were only about half of what we have now]. He started with no Morse knowledge, by the end, he was copying the exchange pretty much all the time, and getting the calls right every now and then. He never got a license however, the concept of having a new logger doesn't always yield a new ham. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 7/3/2015 7:52 PM, Gary K9GS wrote: > Hello David, > > Not singling you out or anything but I've often wondered why you need > separate operator and logger?

I retired in 2009 after 15 years working as comm tech for a major (one of three in Alaska) oil spill recover organization (OSRO). I rarely worked as radio operator but I was in-charge of the total operations of comms which is part of Logistics in the Incident Command System (ICS). Using two operators one primary and other assisting with recording messages improved speed and accuracy considerably. Communications is one of the most difficult parts of an emergency response, and without efficient comms the whole process bogs down. The oil industry had no understanding of ICS when the Exxon Valdez grounded in 1989 so much was learned/improved in the aftermath. The basic form came from military comms and first applied to USFS fire response. Two sets of ears and two heads improves comms a whole bunch (even ham contesting, if it is complicated). Our local FD operation uses computer logging but still often have a logger assistant. Plus It is a great way to introduce FD to newbies. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From w6jhb at me.com Sat Jul 4 15:30:04 2015 From: w6jhb at me.com (James Bennett) Date: Sat, 04 Jul 2015 12:30:04 -0700 Subject: [Elecraft] K3 and 48,000 Hz Digital Issue Message-ID: I posted this on the WSJT-X Yahoo group and still no resolution.

Here is my post: "I just recently upgraded from WSJT-X 1.4.0 to 1.5.0 and have a question about something in the User Guide. I'm running on an iMac, OS X 10.10.4, an Elecraft K3, and my sound card is a Tascam US-125M. I am able to use the K3 and the new version of the software but have an issue with the documentation procedure?. The WSJT-X user manual says to use the Apple Audio MIDI Setup utility to configure the sound card to 48000 Hz, two channel, 16 bit. I have been using the above configuration at 41000Hz with no problems. When I try running at 48000 Hz, the radio does not go into transmit mode. If I switch it back to 44100 Hz, it works OK. The specs for the US-125M indicate that it should work up to 48000 Hz. When set to 48000 Hz, I?m able to get the usual decodes, but can?t transmit. I?ve got it set for the K3/KX3, and CAT control.

He insisted, "We will send right-handed so you can write legibly in your log book with your left." Log books were sacred then [50's], you logged every time you made RF regardless of why you did it. I found my first logs cleaning out when my mom died and every CQ was logged whether it was answered or not [many weren't]. For many years, that's exactly what I did. A number of years ago, we conducted a small survey here on this list and one result was that about 35-40% of respondents who think of themselves as left-handed paddled right most of the time, all of them for my Elmer's reason. 0% of the right-handed respondents paddled left. Sending right really helps if you guest op, most stations are set up for right-handers. As logging requirements were disappearing, I have migrated to left-handed sending and probably do it now around half the time, I have a paddle on each side of the laptop.

With that being done, the SignaLink will likely not produce its PTT output reliably. With the K3, use VOX to initiate transmit rather than the SignaLink PTT - it will work just fine provided you set the VOX gain level correctly. For those who have doubts about my 'solution', consider that the SignaLink uses the audio level to determine whether to activate its PTT output. That is nothing more than a simplified VOX. The K3 VOX is much better at detecting a particular audio level and activating transmit than the SignaLink because the K3 VOX level is adjustable. So ignore the SignaLink PTT output and use the K3 VOX instead to initiate transmit - it will work much better. The alternative is to use the data mode software to put the K3 into transmit rather than depending on the SignaLink PTT output. Most data mode applications have the capability to put the K3 into transmit via an RS-232 command if you set the software up to do that. In other words, do not fight the SignaLink limitations, use it as an external soundcard only and ignore its other functions. BUT then, a better quality external soundcard can be had at less than half the price of a SignaLink and will do a better job. Yes, the SignaLink with its cables specific for the radio you have makes it easy for a beginner to get started, but that simplicity has its limitations, and those limitations have already been expressed in this thread. 73, Don W3FPR On 7/4/2015 7:40 PM, Joe Subich, W4TV wrote: > > > In general the modifications documented on the several web pages > are sufficient.

It was an 80m horizontal loop fed with 450 Ohm line. It would be problematic to change the feed line length, so I did some calculations and found that 300 Ohm line would provide a better match on most bands. The line was changed and the loop length trimmed a bit (not enough). The VSWR was measured across the HF spectrum with a good network analyzer. The result looked good. On 80m, SWR ranged between about 7:1 to 3.5:1. On forty, it was between about 4:1 and less than 2:1. After reading your message, I checked the impedance and SWR again a couple of ways, and although it isn't as good as from the network analyzer, the data agrees pretty well. If anything, the SWR looks better now. The bottom line is that the impedance isn't bad, and I barely need the tuner on 40m at all. In fact, the tuner might be confused by the low SWR, I suppose. Using a tuner with a good load breaks the rule, "If it ain't broke, don't fix it!" The antenna impedance magnitude is between 25 and 80 Ohms in both bands. I could email you the SWR plot I made when the new feed line was put up, if you are curious. Too bad I didn't measure S-parameters. 73, Rob -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Autotuner-malfunction-tp7604565p7604624.html Sent from the Elecraft mailing list archive at Nabble.com.

One of these into your XVxxx transverters are the local oscillators which these days are out of scope of the actual technologies, specially due the digital modulations requiring much more stability than a single XTAL (even equipped with a heater). I'm going to replace the Xtal oscillator of my XV144 with a clean 116MHZ PLL synced 10MHZ, place a small smd PAT-2+ or 3+ (2 or 3db depending of my stock) pad behind the mixer LO input as I'm not sure the 50Z adaptation is perfect, and adjust the LO level at its maximum between 17 to 20dbm according the mixer datasheet to increase the IP3 to the max possible with this ADEX-10H mixer. I know these transverters have been designed many years ago for the k2 line, may be now it's time to revamp them a bit with some new technologies to improve their performances at a level of some other competitive products. For me the main advantage of these transverters is the "interfacing/switching management" within the k3 line and the nice packaging within the line but the RF performances are becoming a bit obsolete.

Or the Heil Gold Elite. I use the PR781 with the W2IHY EQPlus and 8-band EQ and the combo of the already top notch mich and EQ are superb.

There are good guidelines from others on how to set the band gains up. Using the EQ, all three mics sounds about the same. For the EQ, I set the bottom three bands as low as they'll go (-16 dB), then bring it up to 2 dB at 400 Hz, and have some midrange gain through 3.2 KHz. The energy below 400 Hz is not useful for intelligibility. Others can advise you on exact settings, because they're audio pros.

The Heil PR-781 is grossly overpriced. Any quality dynamic mic will work very well with the K3/K3S. For a hand mic look at a Kenwood MC43S (connector matches the K3) or Shure 514B or 596B ($43 at B&H Photovideo). For a "stick" mic to be mounted on gooseneck/boom, look at a Shure PGA48 ($35 at B&H Photovideo). If you need an "off the shelf" amateur mic, the Kenwood MC60A works fine if you keep the internal preamp turned off (otherwise it requires a minor rewiring of the mic plug). Other manufacturers communications/paging mics can be substituted for the Shure but they are a good value for reasonable quality. 73, ...

Since this time the technology has moved up, this is the reason why I decided to improve mine. However once more the design of the packaging (flat, light, pretty... ) and the integration into the k2/k3 line is excellent, this daisy-chaining is perfect, avoiding externally complex and ugly cabling. The shame is there is no 23cm transverter into this XV line, probably I'll integrate one of my 23cm transverters into an XV144 I'll depopulate keeping the IF and control logic parts. My goal is to replace my IC910H (2m/70cm/23cm) with the k3 plus XV series, but with improved performances. You're doing an excellent job guys (Elecraft team), continue going up, we love this.

All of the dynamic mics work very well with the K3. Before one of the guys in our club introduced me to the CM500, I used an RE11 on a boom stand from my music recording stash. I also own two Sony MDR7506 headsets, which I no longer use in the shack because the CM500 is so good. The TX EQ built into the K3 is quite capable, and is all that is needed to tailor TX audio to a mic and a voice. An external equalizer is a waste of money. All it takes to use any dynamic mic with a K3 or K3S is a suitably wired connector or connector adapter cable. For a pro mic with an XL-connector, wire pin 2 to the mic input, pin 3 to mic return, and pin 1 to the connector shell. Or if you have a two wire cable (center plus shield), wire pin 2 to the center conductor and to mic input, tie 1 and 3 together to the shield, and connect to the K3 connector shell. 73, Jim K9YC From rmcgraw at blomand.net Sun Jul 5 13:07:07 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Sun, 05 Jul 2015 12:07:07 -0500 Subject: [Elecraft] Microphone Qusestion In-Reply-To: <5599600A.5050305@audiosystemsgroup.com> References: <55991C2E.1070501@blomand.net> <55992EBB.4000303@blomand.net> <559939DD.1090109@subich.com> <5599600A.5050305@audiosystemsgroup.com> Message-ID: <5599643B.1090901@blomand.net> Thanks Jim.

The best way to control the KRC2?s ACx pins is to do it through the K3?s menu. The KRC2 is listening to the K3 to get band and status information, and not necessarily to a computer. So setting the state in the K3 will cause it to be changed in the KRC2. Take a good look at the K3?s MN command, specifically MN049. I suspect that testing with the K3 Utility?s command pane will quickly show you the correct command to do what you want. From there is is a pretty simple matter to plug the command into N1MM+. By the way, the K3S/K3//KX3 Programmer?s Reference has been seeing a lot of update activity recently. If you haven?t downloaded the latest, you may be missing out on some interesting stuff.

The behavior that I am seeing is likely because the mismatch with the antenna is marginal. At least my K3 is not very sensitive to VSWR less than 1.5:1, and it reports a VSWR of 1.0:1 when other devices are measuring something more. In general it reports a lower VSWR than any analyzer I have tried. Addressing my "problem" on 40 meters, there are good values in the tuner memories for the whole band, but if I change from the high end of the band to the low end, the VSWR sensed by the K3 is not so bad, and I suspect that the K3 doesn't bother to switch to the values in memory for the new frequency. I might like to see less than 1.5:1.0, but the K3 isn't bothering with it. On 80m, my antenna actually does need a bit of tuning. There has been some trouble auto-tuning to get a good match with the tuner around the part of the band where the tuner capacitor needs to switch from the antenna side to the transmitter side or vice versa. This is just a theory, but possibly the K3 sensing of the match is more sensitive depending on which side the capacitor is on. Maybe it makes a mistake sometimes when the SWR is relatively low, like less than 3.0:1. The capacitor seems to end up on the antenna side when there would be a better match if it switched to the transmitter side. I may mess around on 80 and see if I can learn anything else or confirm this. Regardless, my tuner works, and if you use it correctly, there is barely a hiccup.

No, microphones need to be reasonably flat without excess low frequency response, particularly when worked close. Beyond that the K3/K3S TX EQ and noise gate are all anyone needs to achieve excellent sounding audio with any voice. Start with TX EQ set to -16, -16, -6, 0, 0, +3, +5, +6 and touch up the 200 Hz band for your particular voice. Increasing level at 200 Hz will provide a bit more low frequency response at the cost of some "punch" and intelligibility (low frequencies waste transmitter power). For the "DX" sound, change +3, +5, +6 (3 dB per octave pre-emphasis) to +6, +10, +12 (6 dB per octave). Both the low and high frequency adjustments may change a bit depending on the response of the microphone. A "communications" (e.g. paging or "radio") mic will need less pre-emphasis as some is built into the mic element. A recording mic will need even more low cut because of proximity effect (bass build-up). 73, ...

Yes I do that, but you can also do it acoustically i.e. Shure 444. Those who don't know how a 444 works just cup you hands in front of your mouth and hear the difference to your voice. That the principle. Microphones and headphones sound and feel differently. All I am saying is when purchasing, go for one that you like. Not one that I like. Not one that Joe likes. That's my argument. The fact that Joe thinks certain products are over priced is his view, not necessarily everyone's otherwise Heil would not be in business. CL Clive G8POC From jackbrindle at me.com Sun Jul 5 16:03:52 2015 From: jackbrindle at me.com (Jack Brindle) Date: Sun, 05 Jul 2015 13:03:52 -0700 Subject: [Elecraft] KRC2 relay control In-Reply-To: References: <559816D0.6020208@comcast.net> Message-ID: <1977D714-BDD5-403A-BA84-1152FEF733CE@me.com> A bit more on this. Sending MN049; to the K3 puts the K3 into the Menu mode with the KRC2 item selected. The VFOA display will show the status of the KRC2 ACC pins, read directly from the KRC2. You can then issue UP; or DN; commands to change the KRC2 ACx pin setting. It will advance (or decrement) by one for each UP (or DN) issued, rolling over when it gets to the end of the sequence. You can read the LCD with the DS; command to tell what the AC state is. Issuing MN255; will get you back to normal operations. Be sure to refer to the K3S/K3/KX3 Programmer?s Reference to get the details as to how to issues these commands, they can be a bit convoluted, especially when playing in the menus. If you are adding the commands to N1MM, you probably want to use 2, the first to turn on ACC1: MN049;UP;MN255; the second to turn it off: MN049:DN;MN255; This can be a lot more involved if you use the AC2 or AC3 pins as well, and using the KRC2 with AC binary coding (jumper W4 installed) makes things far more complex. Note that external control of the ACx pins requires use of the AUX I/O connection to the K3/K3S. The KRC2 does not have any commands to change the ACx pins using the serial port, nor does the transceiver have the ability to make that request using the serial port instead of Aux I/O. - Jack Brindle, W6FB > On Jul 5, 2015, at 10:47 AM, Jack Brindle wrote: > > Byron is on the right track here. The best way to control the KRC2?s ACx pins is to do it through the K3?s menu. The KRC2 is listening to the K3 to get band and status information, and not necessarily to a computer. So setting the state in the K3 will cause it to be changed in the KRC2. > > Take a good look at the K3?s MN command, specifically MN049.

Heil is in business for the same reason that Bose is in business -- they spend a lot of money on advertising, and their customers don't know enough about the product they are selling to know they're being suckered. In the audio biz, we say of Bose, "better sound through marketing." The same applies to Heil.

I use the Elecraft MH2 microphone and it suits me just fine. Although, I do admit to being mostly CW so the mic is not the most important part of the hobby. But, I get very good audio reports and even though I agree with all the comments about using TX EQ to make adjustments, I have actually never done that. I keep putting that off. Maybe I will do that soon. But, like I said, the MH2 is very good in my opinion and it has several advantages: nice PTT button on the mic is my preferred mode of operation and it does not take up space on the desktop because I just scoot it out of the way where it hides most of the time. 73, phil, K7PEH P.S.

One caveat is making sure the PLL has low phase-noise as that affects ability to handle strong adjacent frequency signals when trying to copy weak signals (which is why you are using JT65). One of the shining parameters of the K3 design. I had DEMI transverters long before I acquired my K3/10 (and KX3) so have continued to use them. I have heated xtal osc on 144 and 222 but use a PLL on 432, 1296, and 3400 MHz. Recent re-design by DEMI has improved xtal LO frequency stability while the xtal oscillator has excellent phase-noise performance. I see about 7 to 10 Hz drift on the 101 to 194 MHz xtal oscillators in the new L-series of DEMI transverters. But LO's for higher bands multiply the xtal oscillator frequency which also multiplies drift. For 432 and higher I found using the N5AC ApolLO PLL's worked well in DEMI transverters. The N5AC Apol series is not the lowest in phase-noise so that could be a real concern for those doing VHF-plus in high density RF environments. So one should consider phase-noise when deciding on a PLL. W1GHZ has a new VCXO design that exhibits lower noise than a PLL. Of course this is for the experimenter ham who DIY. I do think there will be a increasing use of PLL in VHF and higher equipment due to demands of digital modes and need for better frequency stability on the higher bands. One issue is the need for an external 10-MHz reference. That is not hard to embed into current equipment. I did that for a 432-MHz transverter customer. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From ke6te.9 at gmail.com Sun Jul 5 18:15:03 2015 From: ke6te.9 at gmail.com (George Rebong) Date: Sun, 5 Jul 2015 15:15:03 -0700 Subject: [Elecraft] KAT500 won't tune the 6 meter antenna Message-ID: <73B6083A-754C-40FC-9A3B-6B15C0A719B8@gmail.com> My KAT500 doesn't tune my 6 meter antenna.

Check the KAT500 specs on page 2 of the KAT500 manual. The tuner is limited to matching no more than a 10:1 SWR in the HF range, and lower at VHF. Note that this is specified for 500 watts of power, so you may be able to get a little more. 13:1 indicates a very bad match, however. You will be burning up most of your TX power in the coax between the tuner and the antenna. By far the best thing you can do is to fix the antenna so that is presents a much better impedance to the feed line (and thus the tuner). Doing so will get much more of that precious power into the air. - Jack B, W6FB > On Jul 5, 2015, at 3:15 PM, George Rebong wrote: > > My KAT500 doesn't tune my 6 meter antenna.

The Tune function also shuts the K2 down at this point. I observed the same behavior on a dummy load - to eliminate an antenna or feedline issue. I also left the power supply on while letting the K2 cool down to see if it was the source of the problem. Apparently not since the K2 would operate for a significant time after turning it back on.

Starting college, I worked at an FM station as a member of the TX engineering crew and a board op. I had the sign-on shift 3 days a week and was the only one there ... and I should probably include I was 16 and the engineering crew had minimal adult supervision. The mic at the board was the iconic prismatic RCA velocity mic, quite big and I found that, if I crawled up to it real close while reading the sign-on script, I sounded like a 45 yr old bass, highly experienced announcer instead of a 16 yr old teenager. I think this is true for most mic types, that velocity mic just may have been the extreme case. While bass is nice on a 50 Hz to 15 KHz hi-fi broadcast channel playing classical music [think 1812 Overture], you don't want that on a comm channel. K3 TX EQ is extremely effective in tailoring the audio from most any mic. I wonder how it would do using a Bell T-1 carbon element from an old black telephone? 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 7/5/2015 11:13 AM, Joe Subich, W4TV wrote: > > > Microphones have to suit your voice. > > No, microphones need to be reasonably flat without excess low > frequency response, particularly when worked close.

The K2 has a loss of power control and will try to transmit at the maximum power possible. You would see that if you connect an external in-line wattmeter and set the power knob to somewhere between 20 and 40 watts - I suspect the actual power output would be in excess of 120 watts. You will also likely see HiCur messages - and that is causing your shutdowns. You can 'take my word on it', or you can use an external wattmeter to verify that you have no power control and the power output is always at the maximum the K2/100 can deliver. Replacement of D16 and D17 in the KPA100 is in order as the first step. There are other failure points in the KPA100 power output reporting to the base K2 MCU that can cause similar responses (failure of KPA100 U6), but the most common problem is D16 an D17 which can be damaged by static charges on the antenna feedline. If the problem does resolve to the failure of D16 and/or D17, you might want to consider measures to prevent future failures. Put a DC path across each antenna feedline to bleed off static. A non-reactive 5k to 50k resistor will do fine. Then disconnect antennas from the K2 when not in use - a switch to connect the K2 to a dummy load is ideal. 73, Don W3FPR On 7/5/2015 7:28 PM, wa4ywm wrote: > I have a K2 serial no. 4729 with the 100W amp which I have been using for > almost 10 years. > > It recently developed a problem with the following 2 symptoms: > > 1.

(Thats an assumption on my part ok) I won't rant about the WI2HY. I will say i have yet to hear a station using this type of audio that was adjusted to give good audio. My ears are c#@p but a wide signal is still a wide signal and awful audio is still awful. Piercing audio may cut through, but ripping off my headset when they call sends me to the coffee machine and medicine drawer. It does not get a reply from me.

I have tested using DXLabs Commander directly and through LPBridge, N1MM direct and through LPB and the results are the same. Put the rig into AFSK A 45 BPS using the software, check data mode using the DATA MD button and it is correct. Press A>B button twice, the frequency is transferred but the "A > B all" never comes up. Swap operating VFOs and the mode is now DATA A, swap operating VFO's again (Should now have the original frequency and mode of AFSK A 45 BPS) the mode is now DATA A. Further testing reveals that this will occur just by changing VFOs using the A/B button. If you set the mode using DATA MD and the VFO B knob then Press A>B button twice the frequency and mode is transferred to the B. More testing shows that changing the mode using DATA MD and the VFO B Knob actually changes the mode in both VFOs/Receivers. I then tried setting the mode in both VFOs using the following commands in a DXLabs Commander Macro. (The PC020 is to give me 20Watts output) 'k31;md$6;dt$1;bw$0040;is$2210;md6;dt1;bw0040;is2210;PC020; This sets the VFO A to AFSK A 45 BPS, if I put the VFO B/Sub receiver commands second then VFO A resets to DATA A. Please what am I doing wrong? I would like to be able to select RTTY and have both VFOs in AFSK A 45 BPS. Please no responses saying I should be using FSK.

One caveat is making sure the PLL has low phase-noise as that affects ability to handle strong adjacent frequency signals when trying to copy weak signals (which is why you are using JT65). One of the shining parameters of the K3 design. I had DEMI transverters long before I acquired my K3/10 (and KX3) so have continued to use them. I have heated xtal osc on 144 and 222 but use a PLL on 432, 1296, and 3400 MHz. Recent re-design by DEMI has improved xtal LO frequency stability while the xtal oscillator has excellent phase-noise performance. I see about 7 to 10 Hz drift on the 101 to 194 MHz xtal oscillators in the new L-series of DEMI transverters. But LO's for higher bands multiply the xtal oscillator frequency which also multiplies drift. For 432 and higher I found using the N5AC ApolLO PLL's worked well in DEMI transverters. The N5AC Apol series is not the lowest in phase-noise so that could be a real concern for those doing VHF-plus in high density RF environments. So one should consider phase-noise when deciding on a PLL. W1GHZ has a new VCXO design that exhibits lower noise than a PLL. Of course this is for the experimenter ham who DIY. I do think there will be a increasing use of PLL in VHF and higher equipment due to demands of digital modes and need for better frequency stability on the higher bands. One issue is the need for an external 10-MHz reference. That is not hard to embed into current equipment. I did that for a 432-MHz transverter customer. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com Hi Ed, For this improvement I've an EXCELLENT PLVCXO 116MHz which is used intensively in Eu by microwavers, the PN is excellent, even more, I've measured it very recently with an APPH AnaPico source analyser ( www.anapico.com ) . I'm going to build an external enclosure box where I'll include the 116MHz LO for the XV144, the 404MHz LO for the XV432 and a small internal 10MHz distribution amplifier . I'll not remove the existing LO of the XVs, just two SMB bulkhead on the back panel for the in/out LO (SMA are too large for the remaining space), so it would be possible with a small smb jumper to come back to the original LO. There is not enough space inside the XV box to include the PLLCXO without depopulating the initial oscillator, and I don't want to do it. Will need to know the RAL paint number of the XV enclosures, if someone knows it I will appreciate. I would have preferred a XV empty enclosure but I doubt I could purchase one to ELECRAFT so I'll repaint my own enclosure (will not purchase another XV just for the box... Lol...) Concerning the 10MHz most of my radio equipment are driven with the same GPSDO 10MHz distributed from the cellar to the tower for microwave transverters going to be installed soon on the tower itself and to the shack for the radios. The lab has another GPSDO or a rubidium PRS10.

There are two communications speed settings at play. One is the sample rate and bit depth for the USB sound card. That is set on the Audio Tab of WSJT-X, and wants to be 16-bit 48 kHz. The other is communications between WSJT-X and your radio for Rig Control via RS-232 (and perhaps a USB adapter). 38,400 is as fast as the K3 goes, so that's what you must choose, and both the K3 and the radio must have the same setting. As for going into TX -- I use VOX for ALL modes except CW, and it works great. The gotchas are VOX Gain (a menu setting) and Line In Gain (set by the Mic Gain control when the K3 is set for Digital modes. Perhaps all you need is more Line Gain and/or VOX Gain. That's happened to me many times when I've changed setups. The Line In should be set for five bars of ALC, then set VOX Gain to activate TX. If this doesn't get you going, I suggest that you ask again on the WSJT reflector. Some of the developers of WSJT-X monitor it, and may be able to help. Who knows -- there may be a bug they need to squash. When I reported rig control issues with the K3 with a WSJT-X Beta, they thanked me, and several months later it seems to work. 73, Jim K9YC On Sun,7/5/2015 9:18 PM, James Bennett wrote: > Nobody???

From a reasonableness and efficiency standpoint one should not plan anything more than 3:1 as a normal load for a coax in coax out tuner. Less than that as frequency goes up. Particularly 10m and above can have quite a bit of loss if not operated well-matched (1.5:1 or less) over coax long enough to go from a shack outside and up to an elevated antenna. An antenna tuner is not a remote trouble neutralizer. Time to find out what is busted in the antenna up there, or if the coax is cut or crushed. Good luck on chasing down the trouble.

There are two communications speed settings at play. One is the sample rate and bit depth for the USB sound card. That is set on the Audio Tab of WSJT-X, and wants to be 16-bit 48 kHz. The other is communications between WSJT-X and your radio for Rig Control via RS-232 (and perhaps a USB adapter). 38,400 is as fast as the K3 goes, so that's what you must choose, and both the K3 and the radio must have the same setting. > > As for going into TX -- I use VOX for ALL modes except CW, and it works great.

I have provision for that if and as needed. That is one reason I use a 3 wire shielded cable where many installations only use a 2 wire shielded cable. Someone reported that both pin #7 and pin #8 go to a PC board ground. Grrrrrr I know my other radios have a dedicated pin as mike ground and another dedicated as chassis ground. This is connected by a very short jumper, about 3/4", from the connector to the chassis. Once I get the radio I may investigate connecting pin #8 direct to chassis. 73 Bob, K4TAX On 7/6/2015 8:21 PM, Jim Brown wrote: > On Mon,7/6/2015 5:25 PM, Bob McGraw - K4TAX wrote: >> pin #8 as ground. > > Bob, > > Unless you are absolutely certain that pin 8 goes straight to the > chassis, use the connector shell for the shield to be certain that you > don't excite a Pin One Problem. > > 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 rmcgraw at blomand.net > > > From jim at audiosystemsgroup.com Mon Jul 6 23:03:04 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 6 Jul 2015 20:03:04 -0700 Subject: [Elecraft] Microphone Qusestion In-Reply-To: <559B2D68.2030605@blomand.net> References: <55991C2E.1070501@blomand.net> <55992EBB.4000303@blomand.net> <559939DD.1090109@subich.com> <5599600A.5050305@audiosystemsgroup.com> <559AE32A.1060705@blomand.net> <559AFA0F.4060803@subich.com> <559B1C66.7080004@blomand.net> <559B2993.9010905@audiosystemsgroup.com> <559B2D68.2030605@blomand.net> Message-ID: <559B4168.90408@audiosystemsgroup.com> On Mon,7/6/2015 6:37 PM, Bob McGraw - K4TAX wrote: > Once I get the radio I may investigate connecting pin #8 direct to > chassis.

Sure, it is a "pin 1" problem since it does not connect directly to the front panel metalwork, but connecting the shell to the board ground is better than leaving it float. The shield of your mic adapter cable should connect to the shell. I suggest using pin 7 for the AF return and if you add a PTT 'tap', connect the 'hot' side to pin 2 and the return to pin 8. If you connect nothing to pins 5 and 6, those connections will work for both Elecraft and Kenwood mic jacks. 73, Don W3FPR On 7/6/2015 5:58 PM, Joe Subich, W4TV wrote: > > Assuming there has been no change from the late K3, pins 7 and 8 are > both connected to circuit board common.

They are not to be confused with a passive USB hub, which only passes on the power available from the tablet's USB port. Powered hubs are easy to identify as they are usually provided with a wall-wart power supply. I use one to relieve the power duties to devices connected to Raspberry Pi boards. A few catches here: One is the wall-wart is usually a switching supply which may cause harmful hash on it's own. You could replace it with an older linear regulator wall-wart in that case. The other is you might have to split out the power lines from the data lines and craft up a "Y" cable to allow you to provide 5V power to the tablet, and also bring out the two data lines to a cable going to the active USB hub. I'm not sure this will even work as (you are correct in that) sometimes the data lines are shorted together in "USB Power Charger" devices, and that is used by the connected device, to detect that the port is to be configured to accept a charging current as opposed to "data mode" If you can find a way to test that the tablet will charge with a wall-wort that only has two pins connected, you should be in good shape to make the Y cable. In the case of the Raspberry Pi, I have had luck with some powered hubs being able to back feed 5V on the USB data connection and actually power the Pi via it's USB dataport. This also may work for your tablet if luck is with you :) Looks like a bit of breadboarding is in your future Mark.

That way you could connect wirelessly? to the elecraft and still power your tablet.

The large number of posts indicated the amount of interest in the subject matter. So much can be done with the K3/K3S's audio, so many varied mics out there, and so many different user comments. So much to learn - I have only been at the Elecraft game for three years. Too bad to cut this one off. Bill W2BLC K-Line From eric at elecraft.com Tue Jul 7 13:07:23 2015 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Tue, 07 Jul 2015 10:07:23 -0700 Subject: [Elecraft] Elecraft email List Official Guidelines 2015 - Updated In-Reply-To: <4DDEC500.6060701@elecraft.com> References: <4DDEC500.6060701@elecraft.com> Message-ID: <559C074B.50201@elecraft.com> Elecraft eMail LIST GUIDELINES 2015 For those of you who are new to the list, (and for those of us who have rapidly failing memories) here is a quick list of things to remember when posting to this list. Please save this for future reference. The most important thing to remember is that this is a hobby - Let's have fun! The PRIMARY purposes of this list are to provide a polite and enjoyable forum for discussing Elecraft products, share mods, new ideas, feedback to Elecraft, share experiences using our products, troubleshooting ideas etc. The Elecraft email list server (reflector) is provided to further the discussion of Elecraft products and related items. It serves as a forum for the discussion of both technical and operating topics including product features, construction and debug problems, sharing your enthusiasm and impressions from using our products and more general ham radio related topics of interest to our customers. (Please -strongly- resist the urge to reply to an OT topic once it has gone to 5 posts. Once it hits ten posts do not reply at all (go off list if you feel the urge to continue.) Also, please do not try to always get the 'last word'.. 1. YOU MUST BE SUBSCRIBED to the [Elecraft] list TO POST to it. (This is done to stop advertising spammers from hitting the list.) Any postings sent to elecraft at mailman.qth.net by addresses different from the exact ones it shows as subscribers will be rejected. This includes alias (forwarded) addresses like w1xyz at arrl.net. If you use an alias to subscribe you must have it as your from: and return address too. Subscribing with w1aw at arrl.net from your physical address of joe at aol.com will allow you to receive postings, but your postings to the list will be rejected if their from: and reply to: address does not match your subscribe address.. Go to http://mailman.qth.net/mailman/listinfo/elecraft to subscribe and to change your list preferences. To unsubscribe or to change your list preferences (digest, no mail on/off etc.), scroll to the bottom of the page and log in with your subscribed email address and the password that was sent to you by email when you subscribed (and sent to you each month). 2. If you want to provide an attachment, .JPG picture or other large file for use on the list, first post it to your personal web page and then post a link to its address in an email to the list. The list strips all attachments to prevent viruses from propagating and to keep the archives at a reasonable size. 3. Top posting is the official standard for this list, and its especially important for those of us who also read our email on smartphones, iPads etc. Scrolling though a long thread before getting to the reply text is difficult on these devices and costs everyone a lot of time. Reading the response first, at the top, is a huge time saver, especially when you have to read hundreds of emails daily as we do here. We really appreciate your adherence to this. Please also delete -all- footers and as much of the prior email text as possible when replying to cut down on overall email size. Please keep the amount of copied text from previous posts to an -ABSOLUTE MINIMUM- in your replies. 4. EMAIL OVERLOAD: If you are overloaded by the volume of individual messages on the list, You can view the daily Elecraft list messages for each month in web format at: http://www.elecraft.com/elist.html . These archives are updated hourly and list postings by subject. (the Nabble archive looks very useful.) Just click on the ones you are interested in to read. You can also set your Elecraft list email preferences to 'no mail' delivery, which still allows you to post to the list when reading via the digest. You can also change your subscription to the DIGEST version, which sends you a single compilation each day. To change your email list options or to subscribe / unsubscribe, go to: http://mailman.qth.net/mailman/listinfo/elecraft Scroll to the bottom of the page to log into your preferences page and set your mail options to 'no mail'. 4a. Please make an effort to keep list volume under control by resisting the urge to post a comment on every long discussion thread (CW, Soldering etc.) With thousands of list subscribers volume can quickly get out of control if everyone feels the need to comment. While we do not overly restrict the subject matter on this list, please remember that its primary focus is on Elecraft products, and their use. Many people rely on it for pointers on building, using and troubleshooting their rigs. Other ham Radio topics are OK, but please keep the posts on non-Elecraft topics under control. 4b. *** When emailing about a specific rig or option, please add the rig/option name(s) to the first part of your email subject line. (K1, K2, K3, KX1 etc.) This will be a huge help for those experiencing email overload and will allow automatic filtering based on subject line. Examples: "Subject: [K3] Filter Options" "Subject: [KX1] How to use ped portable?" "Subject: [XG2] Wow! Its a big help. 5. *** IMPORTANT - PLEASE KEEP ALL POSTINGS CORDIAL. Restrain the urge to email someone admonishing them about a posting, or snidely commenting on it. The last thing we want to do is to scare anyone off the list. Overly aggressive postings, arguments and negative comments about other posters only serve to scare away new potential Elecraft community members. Waiting over night before hitting 'send' really helps to put things in perspective.. Remember that -everything- you post here is archived and publicly visible for as long as the internet exists. Do you really want your friends, employers, kids etc. reading what you just posted in anger, foolishness, arrogance etc? If you have a complaint about someone or a thread please email it directly to me ( eric at elecraft.com ) and I'll address it. Please do not post complaints about other postings to the list. 5a. Do not post publicly or privately asking people to stop a particular thread, no matter how long, off topic or repetitive it gets. Email me instead. I will step in when I feel it is necessary to end a thread. (eric at elecraft.com) 5a1. Please exercise restraint in posting when a thread is getting heavily covered. 10-15 posts on one topic in a day is excessive. Please do not vote yay/nay or with 'me too' postings. That only clogs our email in-boxes. 5b. Please do not post any direct attacks or snide comments directed at a list member. Enthusiastic arguments are encouraged, but please keep everything cordial. Members who verbally attack or denigrate another (either via the list or via direct email) may be removed from the list. As the only official list moderator, I'll jump in as necessary to keep everything orderly. I do this off line and occasionally to the list when it is appropriate. Our goal is to keep the Elecraft list a fun, relaxed and informative central clearing house for Elecraft information and enthusiasm. 6. There are -no- stupid questions. Please feel free to post your technical questions and comments to the list. (And absolutely do not criticize posters for their questions either on list or via direct email.) Elecraft owners are your best source for quick answers (and they NEVER sleep!) If you don't get the answers you need from the list please email us direct at support(at)elecraft.com , which is our customer service address. We do try to watch the list traffic, but we may not respond to everything immediately and may miss some postings sent to the list or our personal addresses. 7. Please do post your experiences with your Elecraft kit, DX worked, crazy ideas, product ideas, complaints (yes - we do want to hear them, but please keep it polite . 7a. Commercial postings are allowed if they relate to Elecraft products, QRP, QRO, home-brewing, building etc. and are of interest to this list's membership. Please keep them as short as possible and provide web links to more detailed information. I'll step in if we feel someone is posting too many messages of this type. 7b. Please limit commercial postings to one per month per offering or product area (i.e. Builder for Hire postings, ham radio related products etc.) 8. Also, please -DO NOT USE CAPS- to emphasize words or phrases. This is interpreted as shouting rudely on the internet. If you want to emphasize something, surround it with -dashes-. 9. Send parts requests direct to parts at elecraft.com, instead of to the list. 10. If you don't get an answer to a question from the list, or by searching the list archives, don't forget to check the Builder's Resource Page at http://www.elecraft.com and our support email address: support at elecraft.com 11. Please note that Wayne, myself and our support staff do not read 100% of the emails on this reflector - especially when we are busy at hamfests, ramping up new products in production etc. If you expect us to reply to a posting, and we do not do so, please email us directly or contact our great guys at support at elecraft.com 12. And above all, HAVE FUN!. We hope that this list is both a good technical resource and that it serves as a Elecraft community gathering place. We enjoy reading it every day and it really helps us keep our energy level high so we can continue getting exciting new products out the door to you! 73, Eric WA6HHQ Elecraft COO, List Moderator, Modulator etc. From eric at elecraft.com Tue Jul 7 13:09:50 2015 From: eric at elecraft.com (Eric Swartz - WA6HHQ, Elecraft) Date: Tue, 07 Jul 2015 10:09:50 -0700 Subject: [Elecraft] Crikey! Please edit replies down to a minimum size and delete extra footers In-Reply-To: References: Message-ID: <559C07DE.7080709@elecraft.com> When replying to emails on the list, please remember to edit down the copied text to the minimum needed to retain context. One or two sentences from the original post are usually sufficient. This keeps the list and archive volume down and makes everything much more readable. *** Don't forget to delete the list footer message too or you will have multiple copies of it in your reply. A large part of our readers get the list in daily digest mode. When large amounts of previous posts are copied over and over it makes the digest very large and virtually unreadable. Also, many of our readers outside the U.S. pay for email by the kB and are using slower modems.

I have three that all look in "new condition". This coming out of an estate of a recently sk ham up here. All three tested with up 15w saturated output with about 1.5w drive. Nominal 1w provides 10w which is advisable for modes like FM or digital, and for SSB to avoid overdriving. I was able to get a manual and schematic for the amp to ID the three spring-loaded contacts. Two are associated with ALC and one is the TR ckt which takes +13.5v. These amps were a clamp-on option to the Yaesu FT690R (2.5w) that was produced in the 1980's. I'm using one to provide full drive for my 150w 6m Mirage amp (needs 10.5w). Both my K3/10 and KX3 only provide 8w on 6m which drives my Mirage to a tad over 100w (tad = 1-2w). I left the ALC terminals unconnected. I am selling the amps (tested) for $10 plus shipping which is about $10 via priority mail (to USA). I have one at the moment but more available in Anchorage (which I would have to have shipped down to me).

They are relatively new - there aren?t that many USB-C systems out so far, so you should expect them to be somewhat expensive. But, the adapters are available. I know that Apple sells one for their MacBook, which uses USB-C. Might be a good starting point, but keep looking to find what you really want. A standard USB hub will not provide what you need... 73, Jack, W6FB > On Jul 7, 2015, at 8:57 AM, Mark N2QT via Elecraft wrote: > > Actually the issue is the tablet is able to supply power to external devices, which must be > disabled when the unit is being charged from an external source.

Great gobs of personal time and frustration are saved by looking FIRST to the mechanical, then third-party adjunct programs, then to the manual (I know, I know, everyone HATES to read the manual). If you are new to Elecraft equipment, then the order is FIRST to the manual, then to the mechanical, then to third-party adjunct programs. Get a PDF copy of the manual, so you can use the search facities of the FREE Adobe Reader to find stuff quickly in the manual. Suffer with the manual for a few months. Ignore the headaches, PTSD, bleeding from the ears, and mental illness issues reading the manual may cause. They are temporary and will go away in a few years. If you think about it, the K3 firmware has been undergoing continuous high stress field testing and bug-fixing since 2008. Should one really reasonably expect the K3 firmware to be sloppy at this point? Good luck on all your issues, and may you please figure them out quicker than I do :>) 73, Guy K2AV.

But it does take a bit of courage (and a good pair of tweezers, and maybe a shot of cheap whisky) to install them by hand. Hats off to our intrepid customers attempting this for the first time! 73, Wayne N6KR P.S.

K7OLN lives about 750 feet from me, and we both have static antenna setups, and because he is running WSPR K7OLN also has static power levels for these tests. The three test states are as follows: 1. The first P3 capture is K7OLN's K3, using the old synthesizer, as received on my K3 using an old synthesizer. 2. The second P3 capture is of K7OLN, using the same equipment on both ends, save the new synthesizer on my rig only, and received on my K3. 3. The third P3 capture is after K7OLN upgraded his K3 to the new synthesizer, with both radios using the new synthesizer. I have a personal Wiki, and have published the data there at: http://nk7z.net/wiki/elecraft-k3-macros/elecraft-k3-xlr-to-radio/elecraft-k3-new-synthesizer/ Not scientific, but close... As can be seen the new synthesizers make a BIG difference. Bigger than I would have thought! THANK YOU ELECRAFT! K7OLN's purchase of a K3, (I want my Hat Elecraft!), made it such that both he and I can operate on the same band, in the same segment, as close as 10 to 15 KHz away from each other and not even know the other station is there, save the HUGE spike in the P3, (which is supposed to be there), all while at KW power levels for both of us. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net For MixW support see; http://groups.yahoo.com/neo/groups/mixw/info For Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info For MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info From k9fd at flex.com Tue Jul 7 18:55:32 2015 From: k9fd at flex.com (Merv Schweigert) Date: Tue, 07 Jul 2015 12:55:32 -1000 Subject: [Elecraft] K3 KBPF3 mod for LF questions capacitor size ?

What works for me is a small "helper" I made. Actually the first of two; the second is much more elaborate. ? I do my boards flat/horizontal in a holding fixture so it doesn't move around. ? Then I made a 'T' shaped wire 'holder' that rests on the 'T' crossbar. The leg of the 'T' is long enough to bend into a 'C' as big as needed to reach the part. The end of the leg is sharpened to a small rounded point about 2/3 the width of the SMT or 0.02" and rounded with emery paper. A weight is added to the leg an inch or so above the point. In use I place the part with tweezers or other tool and then set the holder tool working end on top so it holds the SMT part in place. Careful use of the solder pencil tip does the trick. Takes?a bit of practice but worked well for me. My newer design works better but is, as I say, more complicated to build but as simple to use. Same principle though. ?

Surface mount work takes skill and calmness. I compare it to the process precision shooters use. Breathing in/out and out half-way and hold will calm nerves. Mental thinking to calm yourself vs saying "do not shake" is some of the zen stuff that works. Resting the heel of your hand on something helps holding still. Whisky or some of that tobaccy that will mellow you...but you might get munchies so caveat emptor! (legal in only three states) Bees wax or putty with a toothpick are beginners methods. Professionals get a fine jeweler's tweezer to hold sm. Use what works for you. Soldering a sm cap on top of an existing cap is a little tricky. Add a bit solder to one end of the existing cap so the new cap can be slid into it. You melt that solder with iron and slide in the top cap - hold - carefully remove iron -keep holding a couple seconds till solder solidifies. Now add a bit of solder on the other end. Use an ohmmeter to test continuity from the top cap to the pc trace where the cap is installed. Good continuity - you're done! Continuity across the cap - bad - do over. If this is just too hard for you, then find a local ham to help you with it. Or send it to Elecraft. The filter is not large so not real expensive to ship.

If it was advertized as a fully working radio, you may have recourse with the seller for either a refund or a repair. OTOH, if the seller did not state that it was working properly, you may have to investigate and fix it yourself. Normally, the K2 will not go to a display of the power output - it should come up in receive. Disconnect everything from the K2 except for the power cord and the antenna connection. To help with diagnosing the problem, connect the K2 to a dummy load. If this is a K2/100 (with KPA100). connect the dummy load to the SO-239 jack. If a K2/10, connect the dummy load to the ANT1 jack on the upper rear panel if the KAT2 is installed, or to the lower rear panel ANT BNC jack if the KAT2 is not installed. If you want to troubleshoot it yourself, you can email me directly and I can help. Please include the configuration and installed options for your K2 as well as the serial number. 73, Don W3FPR On 7/7/2015 6:08 PM, Mauricio Fernandez via Elecraft wrote: > Hello > > I'm just new in the Elecraft world.

Much of the problem is with the fear of small parts. If you have 'eye problems', a magnifying headband can be a great help. Tweezers are a great tool, but be cautious with their use. Too much grip on the part can send it flying to parts unknown where it becomes vacuum cleaner food. A touch just light enough to secure the part is what you want. I prefer straight tweezers while others prefer the angled type - it all depends on how you hold them to determine which is best for you. If you naturally put the main body of the tweezers in your palm, then the angled ones will work best for you. I leave the main body 'sticking up in the air', so straight tweezers work best for me. The prior advice about tinning (putting a small pool of solder) on one end of the existing capacitor is correct. Heat that solder while sliding the added capacitor atop the existing one - when it 'sticks', go solder the other end, and then come back and dress up the soldering on the first end. I don't know about the calming effects of Whisky or tobacco for "mellowing", but if you have some technique for calming "the shakies", use it. Age is doing its thing on me, and I am beginning to feel the effects of 'tremors'. I find I need to support the heels of my hands on the board or the bench surface to counter that problem. Despite that, I am able to solder SMD components as small as 0603, and I am fortunate that my eyes allow me to do that part without magnification - I then inspect the work with magnification afterwards and make corrections as needed. Use magnification at the start if you are not so fortunate. If you need "Microscope" enlargement, then a webcam on your computer may be the answer to your problem - that is a 'cheap hams microscope'. In other words, with these hints, give it a try. I wish you success. 73, Don W3FPR On 7/7/2015 8:46 PM, Edward R Cole wrote: > OK, brace your self, but I told you so (a few weeks ago) - not > specifically you, Emory. > > Surface mount work takes skill and calmness.

If it was advertized as a fully working radio, you may have recourse with the seller for either a refund or a repair. OTOH, if the seller did not state that it was working properly, you may have to investigate and fix it yourself. Normally, the K2 will not go to a display of the power output - it should come up in receive.? Disconnect everything from the K2 except for the power cord and the antenna connection.? To help with diagnosing the problem, connect the K2 to a dummy load. If this is a K2/100 (with KPA100). connect the dummy load to the SO-239 jack.? If a K2/10, connect the dummy load to the ANT1 jack on the upper rear panel if the KAT2 is installed, or to the lower rear panel ANT BNC jack if the KAT2 is not installed. If you want to troubleshoot it yourself, you can email me directly and I can help.? Please include the configuration and installed options for your K2 as well as the serial number. 73, Don W3FPR On 7/7/2015 6:08 PM, Mauricio Fernandez via Elecraft wrote: > Hello > > I'm just new in the Elecraft world.?

But in reality every VFO has width, and it occupies not only it's nominal frequency but is "smeared" both lower and higher in frequency, too. This is because of the phase noise of the synthesizer or VFO. Because of the smearing effect of this phase noise, received signals can also appear wider than they are. The noise floor on either side rises in direct proportion to the synthesizer's phase noise. Dave's screenshots of the P3 spectrograms show this smearing clearly. An oscillator with less phase noise looks more like that ideal picture we all have in our heads -- of a signal that's infinitely narrow. In the third of Dave's screenshots you can see how the new synths are closer to an ideal oscillator-- the CW signal's width on the spectrogram is much narrower.? If a signal has lower noise sidebands (whether the sidebands are generated in the transmitter or the receiver... each of them has a synthesizer) then you can enjoy less interference from an adjacent signal. You will also *cause* less interference to your neighbors on the band. I have no idea of the design of the new synths, but in general to design a synthesizer with low phase noise you have to start with very low noise devices, pay really careful attention to the parts of the phase-locked loop like the Q, feedback, the numeric dithering, the loop filter and various other aspects of the circuit. It's a real art. It appears from Dave's observations that there is a significant and measurable difference.

After doing thousands, yes thousands, this is what I use. First, don't drink coffee for three days before you work. It's called caffeine palsy. It's not compatible with SMDs. Second, if the tweezers don't draw blood when they contact the flesh, they aren't shape enough. Third, get some bottled rosin flux. Thin it 50/50 with alcohol. Then paint the target area on the PCB with the 50/50 flux. Then place the chip components in their target locations. The flux will keep things in place for soldering. I use a combination of tweezers and an exacto knife to align and nudge parts into place. I use the blade to hold down pressure in the middle of the part while I solder. I use up to three soldering irons with tips to much the part. Get on and off the part in 2 seconds which means you need a hot iron. It's called one touch soldering. Set temperature, if you can to 750 to 800 degrees F. I work under a 10 power scope switching to 20x for 1x2 parts. 73 Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Hank P Sent: Tuesday, July 7, 2015 2:32 PM To: Elecraft Subject: Re: [Elecraft] K3 KBPF3 mod for LF questions capacitor size ?

That means you can work closer to the frequency of another station without him interfering with the station you are trying to copy. On transmit, it means your signal is more 'pure' and the sideband 'clutter' on your signal is significantly reduced. Those parameters are important in contest operating and when working in a pileup. 73, Don W3FPR On 7/8/2015 12:31 AM, Robert Clark wrote: > Interesting reading. What does the synthesizer actually do?

Is the smearing caused mostly by the phase noise sidebands, as a resultant of phase flicker? i.e. If the phase noise were reduced on a transmitting VFO, then the smearing would also be reduced, because the sidebands would no longer reflect the wide band phase noise, as-- well-- sidebands? Is this correct? If so, then does that mean that as a station gets stronger, one picks up more of the phase noise, (a function of how far from center one is), and that is why a signal gets wider as it gets stronger? It occurs to me that the the the RX VFO phase noise would be less influencing, (on phase noise sidebands), than the transmit VFO phase noise... Is that correct?

Well, there is one thing you did not do. A fourth condition, which would be difficult, a lot more work given what you were doing. That would be changing his syn first and noting the difference. It might be that the TX change first would create a different middle picture in the series. But I doubt it... These are not linear additive behaviors, and explaining noise reduction from various sources is often very complex. The appearance in the *frequency span* of the heavy continuous noise is cut in half in the middle picture and then cut in half again in the third. That would appear that the combining is a multiplicative function. The difference at a given frequency would then be completely a child of the shape of the noise curve, rendering the reduction at some frequencies as an "effectiveness" measure pretty meaningless. Noting that the heavy noise bandwidth is halved and then halved again presents a better assessment. By that measure the changes are equally effective. 73, Guy On Wed, Jul 8, 2015 at 9:02 AM, David Cole wrote: > Al, > > Let me pose a set of conditions, and see if I understand this... > > Is the smearing caused mostly by the phase noise sidebands, as a > resultant of phase flicker? > > i.e. If the phase noise were reduced on a transmitting VFO, then the > smearing would also be reduced, because the sidebands would no longer > reflect the wide band phase noise, as-- well-- sidebands?

Let's say the phase noise of the new synthesizer is 10 dB better than the old at a particular offset frequency. That is, 1/10 the power. If you replace one synthesizer (RX or TX) then the total phase noise is reduced by a factor (1 + 1/10) / (1 + 1) = 0.55 or -2.6 dB. If you replace both synthesizers, then the total phase noise is reduced by a factor (1/10 + 1/10) / (1 + 1) = -10 dB. I don't think it makes any difference which synthesizer is changed first.

(This is a famous rule-of-thumb we use in any measurement.) From the anecdotal reports we're reading here, the K3 has probably reached that point as compared to many other rigs, especially if they're close by. Al? W6LX If so, then does that mean that as a station gets stronger, one picks up more of the phase noise, (a function of how far from center one is), and that is why a signal gets wider as it gets stronger??

Message-ID: <559C82C1.1060602 at embarqmail.com> Content-Type: text/plain; charset=windows-1252; format=flowed I can vouch for what Ed has said. Much of the problem is with the fear of small parts. If you have 'eye problems', a magnifying headband can be a great help. ------------------------- I use a 8-inch round magnifier lamp (new one has LED bulbs). Finding I have to use it most of the time now that my eyesight is deteriorating (mac degen); so how many more years I can do this is ?? ------------------------- Tweezers are a great tool, but be cautious with their use. Too much grip on the part can send it flying to parts unknown where it becomes vacuum cleaner food. A touch just light enough to secure the part is what you want. I prefer straight tweezers while others prefer the angled type - it all depends on how you hold them to determine which is best for you. If you naturally put the main body of the tweezers in your palm, then the angled ones will work best for you. I leave the main body 'sticking up in the air', so straight tweezers work best for me. ------------------------- Mine were given to me by a jewler-ham; 4-inch long with slight tips angled. I hold mine in left hand like a pencil. I am right-handed so it holds the solder iron (HAKKO FX951). ------------------------ The prior advice about tinning (putting a small pool of solder) on one end of the existing capacitor is correct. Heat that solder while sliding the added capacitor atop the existing one - when it 'sticks', go solder the other end, and then come back and dress up the soldering on the first end. I don't know about the calming effects of Whisky or tobacco for "mellowing", but if you have some technique for calming "the shakies", use it. --------------------------- That was said as humor. Best solder sober! I do most work in morning before much coffee. I limit work to about 4-hours in a session. If building a sm kit, installing some parts is easier before others - experience helps. --------------------------- Age is doing its thing on me, and I am beginning to feel the effects of 'tremors'. I find I need to support the heels of my hands on the board or the bench surface to counter that problem. Despite that, I am able to solder SMD components as small as 0603, and I am fortunate that my eyes allow me to do that part without magnification - I then inspect the work with magnification afterwards and make corrections as needed. Use magnification at the start if you are not so fortunate. If you need "Microscope" enlargement, then a webcam on your computer may be the answer to your problem - that is a 'cheap hams microscope'. In other words, with these hints, give it a try. I wish you success. 73, Don W3FPR 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From gerry at w1ve.com Wed Jul 8 14:02:35 2015 From: gerry at w1ve.com (Gerry Hull) Date: Wed, 8 Jul 2015 14:02:35 -0400 Subject: [Elecraft] Fwd: Windows 8.1 tablet power In-Reply-To: References: Message-ID: Hi Mark, Get the following Dell Cable: 470-ABESDell Adapter - Micro USB for Data and Charging ?It has microUSB to tablet, microusb for power, and then microusb to power external device.

It is not totally agreed but much thought is that MDS is lowered by having low phase-noise (even in a completely quiet band (no adjacent signals). Thinking is that phase noise *somehow* combines with antenna noise and internal amplifier noise (NF) to limit MDS. W1GHZ has recently been *playing* with VCXO's in place of PLL's and states that he is seeing a 2-dB reduction in MDS level as a result. The voltage-controlled xtal oscillator takes advantage of the better phase noise of the xtal osc. Many PLL use a VCO which is wide frequency in range which is much harder to design for low phase noise (Wayne and co. can probably tell us a whole bunch about that). This is probably of no concern on LF/MW/HF/6m due to the much higher sky noise being the limit on MDS from new equipment (K3 MDS -140 to -145 dBm on 6m). My 2m-eme station MDS is about -155 dBm without adding antenna gain (21.3 dBi). MDS does not add in the effect of antenna gain or sky noise. It is also referred to as Trx (receiving system noise temperature). This stuff is not in the normal HFers vocabulary...my apologies. But I am excited to learn of the improved Synth for the K3s and upgrade for K3. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From w6jhb at me.com Wed Jul 8 16:36:00 2015 From: w6jhb at me.com (James Bennett) Date: Wed, 08 Jul 2015 13:36:00 -0700 Subject: [Elecraft] K3 and 48,000 Hz Digital Issue In-Reply-To: References: <933AB283-64BA-473C-9B93-09EB5C1BBAF4@me.com> Message-ID: All - just wanted to send an update to this group - already did it on the WSJT-X Yahoo group.

In an ideal system, the receiver sees the convolution of the transmit signal, as conveyed by the antennas and progagation and the receiver's LO. So for the most part, I think TX and RX phase noise hurt equally (when viewed in dBc/Hz at some separation). Of course, RX phase noise is under one's control, and TX is imposed on others, so from that viewpoint TX phase noise is more like crossing the yellow line than hitting a tree yourself. >From the measurements I've seen, I don't think it's a fair assumption that transmit and receive phase noise in a given rig is the same. The K3 (with original synth) has a transmitter which is relatively cleaner than RX reciprocal mixing, according to: http://www.sm5bsz.com/dynrange/dubus313.pdf But in many radios (including the KX3), that article says that the transmitter is worse than the receiver. Also see: http://k9yc.com/TXNoise.pdf which focuses on lab measurements of transmitters, disconnected from receiver issues. Presumably the spectrum analyzers are good enough that they're not an issue, but I wonder if that's really true given the levels we're talking about. I think QST reviews should give some measurement of joint TX/RX noise. Perhaps the isolation required so that with one instance of a transceiver at 100W, the 2nd instance receiving at 100 kHz separations (perhaps for 2/10/50/100/200 kHz) ees some particular absolute level of noise, picking some level that is about 10 dBo worse than typical MDS. This is trying to capture "what happens when you have two of Rig X at Field Day in the same band", or the 300m neighbor situation. 73 de n1dam From jim at audiosystemsgroup.com Wed Jul 8 21:43:12 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 8 Jul 2015 18:43:12 -0700 Subject: [Elecraft] Observation on new Synthesizers for K3 In-Reply-To: <559D5DAE.6030503@horizon.co.fk> References: <1436330283.1058.35.camel@nostromo.nk7z> <1325514801.908737.1436332456281.JavaMail.yahoo@mail.yahoo.com> <1436360576.1058.61.camel@nostromo.nk7z> <559D45A9.9080301@sonic.net> <559D4A23.9040803@sonic.net> <559D5DAE.6030503@horizon.co.fk> Message-ID: <559DD1B0.3040703@audiosystemsgroup.com> On Wed,7/8/2015 10:28 AM, Mike Harris wrote: > The transceiver in question is an FTDX5000.

I've used other radios which do have great audio, both on receive and transmit. I find it very important that a good mike suited to the user's voice and good microphone technique is a large part of the key to great audio on SSB. {key words here "{suited to the user's voice} and {good microphone technique}. 73 Bob, K4TAX Soon to be a new K3S owner.

The K3 TX audio can be tailored using the 8 band TX Equalizer which can be used to make most any microphone sound like the best studio microphone in the world if you are inclined to do a bit of tailoring - no need for an external equalizer, it is built in. If you have a K2, you may be interested in the following - If not, you may want to hit the delete key now, the rest is K2 related. I do not think Gary has aligned many K2s in the past few years. I have handled most of the more recent Elecraft K2 repairs, and do not see your call in my records, so I am wondering just how long ago that alignment was performed. You may want to look at your K2 rather than the microphone. I would hate to see you spend $50 or so on a mod to your microphone and find no added benefit because of limitations in your K2 or your SSBA and SSBC menu settings. K2s that I have aligned often garner unsolicited TX audio reports, and I have received that report from many customers. The MH2 does have the peaking response in the 2800 to 3200 Hz region - the same as many other ham microphones. How old is your K2, and what is the width of the KSB2 filter (2.1kHz or 2.4kHz)? The early KSB2 boards had the 2.1kHz filter while later ones have the 2.4kHz filter - that filter is used on transmit as well as receive. To determine which one you have, look at the capacitor row just to the left of the crystals on the KSB2 board - if all 6 capacitor locations are populated, you have the earlier 2.1 kHz filter, but if there are only 4 capacitors fitted, it is the 2.4 kHz filter. Should you want to change the filter width, Elecraft has the SSBCAPKT available to do that - but check the crystals first. If they are labeled anything other than 49136-S, you must replace the crystals when widening the KSB2 filter. If your KSB2 has the older crystals, your base K2 RF board likely has the older crystals as well and will result in better filters if replaced. Elecraft has a set of 7 matched crystals as well as a matched set of 14 available. The other thing that will affect your SSB transmit (and receive) audio is the placement of the audio passband for LSB and USB. That may be corrected by proper filter alignment (CAL FIL). There is another thing that can affect the K2 TX audio, and that is too much bass. The KSB2 does allow low bass frequencies to be transmitted. While some hams like that, it uses excessive power in the PEP envelope. You can reduce that response by changing 2 capacitors on the KSB2 board. Change C34 to a 0.47uF electrolytic and change C32 to a capacitor between 0.0033 and 0.005 uF. (4700pF is an easily available mid-range value). 73, Don W3FPR On 7/9/2015 11:06 AM, Eddy Avila wrote: > Has anyone sent their Heil MH2 to AB5N Bob Nagy for his upgrade?

I also have a K2 with an added IF port (Z1000 buffer kit,Clifton Laboratories). My original intent was to use Larry Phipps', N8LP, LP-Pan-2, with my modified K2 and software like NaP3 as a panadapter, but now I have a PX3. Originally I used this setup with my Kenwood TS-850 and an external sound card. The LP-Pan2 has crystals for both radios. Now my question, can the K2 using LP-Pan2 I/Q ports be used to drive the PX3, and if so how well will it integrate with the PX3? 73, Al ve7ear From toms at xmission.com Thu Jul 9 20:52:28 2015 From: toms at xmission.com (Tom Schaefer) Date: Thu, 9 Jul 2015 20:52:28 -0400 Subject: [Elecraft] MH2 question In-Reply-To: <559EFF3D.1090902@blomand.net> References: <7C04AA3C-F167-4A06-A6D1-1183F023A9A5@mac.com> <1958334733.2066719.1436481297600.JavaMail.yahoo@mail.yahoo.com> <159D6452-E176-42A6-B507-5BC3A836B492@elecraft.com> <559EFF3D.1090902@blomand.net> Message-ID: <50A71D85-E901-487F-8A17-5FB2F9ADC9C5@xmission.com> I'm missing something.

If the discussion is to morph to the K3 and its receive audio, someone needs to change the subject line. The K3 does have the RX EQ which can change the RX audio substantially. The internal speaker is pretty good, but is not of "Hi-Fi" quality. Put a pair of good bookshelf speakers on the rear speaker jack and the character of the K3 receive audio changes drastically. 73, Don W3FPR On 7/9/2015 8:52 PM, Tom Schaefer wrote: > I'm missing something.

Just upgrade the synthesizer, and that is about all you will need for Rag Chewing, etc... Now, if you decide to start hunting DX, etc, then you might start to worry... I have a comparison between the old and new synthesizers at: http://nk7z.net/wiki/elecraft-k3-macros/elecraft-k3-xlr-to-radio/elecraft-k3-new-synthesizer/ using P3 screen shots to show what happens before and after new synthesizers are added to two different K3 rigs, at two different stations, with antenna about 700 feet apart. -- Thanks and 73's, For equipment, and software setups and reviews see: www.nk7z.net For MixW support see; http://groups.yahoo.com/neo/groups/mixw/info For Dopplergram information see: http://groups.yahoo.com/neo/groups/dopplergram/info For MM-SSTV see: http://groups.yahoo.com/neo/groups/MM-SSTV/info On Fri, 2015-07-10 at 09:07 -0400, Bill wrote: > After reading all the posts about the improvements that can be made now > (and in the near future) to the K3, I find it difficult to decide > between a new K3S or to add the upgrades as they become available.

Add the new synthesizer(s) and you will have most of the performance improvement available. Look at the K3S FAQ for a good deal of additional information when considering whether to upgrade or switch to the K3S - or to keep your K3 as it is now. 73, Don W3FPR On 7/10/2015 9:07 AM, Bill wrote: > After reading all the posts about the improvements that can be made > now (and in the near future) to the K3, I find it difficult to decide > between a new K3S or to add the upgrades as they become available.

It's been awhile since I last set it up, I was using it at my winter home for several months without a problem, but can't get it to work here. I have the feeling I'm forgetting something. Here's my setup and the problem. I'm connected to the internet via Comcast. I'm at my summer home, and just had the new Comcast router installed yesterday. I'm using a WiFi extender that I used in the past with no problem, the extender is configured with my connection ID with a _EXT extension, without a password. The RRC 1258 is connected to the extender via an Ethernet cable, the setup I've been using with no issues. When I run the Microbit setup program using a USB cable connected to the RRC 1258 I'm seeing the local RRC, but not the remote one at the K3 site. I vaguely remember that I should be seeing both RRC 1258's ? But I'm not sure. Anyway when I turn on the K3/0 mini I get the connect beep(not the no-connection alarm) but the K3/0 shows a freq and TERM and the controls are inoperative, turning the main VFO does nothing, etc. So to recap. 1. I think I should see both RRC's in the Microbit s/w config window ? 2. Do I need to enter the login info for the local router, but I forget where to do so if true. Anyone have anything for me to try while I wait to call Elecraft support ? 73 Jeff kb2m From elecraft at mailman.qth.net Fri Jul 10 10:14:32 2015 From: elecraft at mailman.qth.net (Michael Gillen via Elecraft) Date: Fri, 10 Jul 2015 14:14:32 +0000 (UTC) Subject: [Elecraft] MacOSX Logging Software In-Reply-To: References: Message-ID: <147128783.2578832.1436537672769.JavaMail.yahoo@mail.yahoo.com> Byron, I have not used the RUMsoft (yet) however I am happy with MacLoggerDX. Besides just logging the QSOs there are many more features, with the DX Clusters being one that is really neat. It integrated well with my K3. When you change the VFO, it shows in the software. When you click on a DX Spot, it changes your VFO to that frequency, etc. I do not have a rotor (yet) however I am sure that also likely works well too. Every feature works well. You can export one or more QSOs to an QDIF file which is the standard for QSOs. They can then be loaded into LoTW and eQSL etc. You can also confirm QSOs by importing an ADIF from LoTW which is nice. It has a lot of features. Support is tops. The developer typically?responds within an hour. He is very nice to deal with. It was well worth the $100 Shoot me an email at mmgillen at me.com if you'd like to discuss offline. 73,MichaelKK6RWK From: Anthony Scandurra To: NZ3O at arrl.net; Elecraft Reflector Sent: Friday, July 10, 2015 4:42 AM Subject: Re: [Elecraft] MacOSX Logging Software Byron, Check this one out... http://www.dl2rum.de/rumsoft/RUMsoft_Home.html 73, Tony K4QE On Fri, Jul 10, 2015 at 7:37 AM, Byron Peebles wrote: > With my migration from TenTec to Elecraft, I was planning to also move my > logging and station control from Windows to MacOSX.?

Never did computer logging until I got my iMac. I tried MacloggerDX and really like it. Mind you, I don't do rotor control nor do I have anything to do with clusters. I operate HF CW and occasionally SSB. I do like the way MLDX tracks my DXCC and WAS data. Don Agro, the author, is very responsive to questions and suggestions for enhancements. While it is not free, you are allowed to use it on several computers, if so desired. My shack/main MLDX logging computer is an iMac. I also run the software on our MacBook Pro occasionally. I use MLDX with my K3 and KX3. A year or so ago I started doing some JT65 and JT9 operating using WSJT-X. There is a free program called JTbridge that interfaces with MLDX - when a QSO is "logged" in WSJT-X, JTbridge will automatically add it to your MLDX database - very slick. I've not used other Mac-based logging programs, but I would definitely recommend MLDX, at least for a trial to see how you like it. BTW - the MLDX database is a SQLlite file and if you are interested in building your own queries and subsequent reports, that database is easily accessible via SQLlite database utilities found on the Internet. 73, Jim Jim Bennett / W6JHB Folsom, CA > On Jul 10, 2015, at 4:37 AM, Byron Peebles wrote: > > With my migration from TenTec to Elecraft, I was planning to also move my logging and station control from Windows to MacOSX.

What in this list will improve TX audio -- other than the KSYN3A (which I already have in my K3)? Speaker audio improved, yes, but that seems to be RX only. FWIW -- I think the K3 is already a "great" radio, but agree that the K3S will be still greater. But for me, if I had to choose only one item on the list below, it would be the KSYN3A -- and I've already chosen to add it to my lowly K3 :-) Of the other items below, I've already added the coverage of 630 m and below, and will likely add the new DSP board with its RX audio improvements when it comes available. 73, Phil W7OX On 7/9/15 7:51 PM, Bob McGraw - K4TAX wrote: > {was MH2 question} > > Here's the enhancements and improvements to the K3S > > From the K3S data sheet: > * Enhanced look and feel, with new LCD bezel, > soft-touch VFO knob > * Ultra low-noise synthesizer for exceptional > strong-signal receive performance and transmit > signal purity (KSYN3A) > * USB port?integrates remote control and > line-level audio, eliminating the need for a PC > sound card and audio cables > * Second preamp for 12-6 m weak signal work (on > included KXV3B module) > * Multiple attenuators, providing steps of > -5/-10/-15 dB > * Lower-Loss ATU option with true bypass relay > (KAT3A) > * Redesigned AF output circuitry for outstanding > speaker audio > * Accurate, high-speed CW transmit even in SPLIT > mode > * Coverage of the 630-meter band (~470 kHz), and > lower > > IMO - these are things that will make a good > radio a great radio. > > 73 Bob, K4TAX > > From w7ox at socal.rr.com Fri Jul 10 10:37:36 2015 From: w7ox at socal.rr.com (Phil Wheeler) Date: Fri, 10 Jul 2015 07:37:36 -0700 Subject: [Elecraft] K3: Upgrade or replace In-Reply-To: <1436534288.1058.118.camel@nostromo.nk7z> References: <559FC39A.5080309@nycap.rr.com> <1436534288.1058.118.camel@nostromo.nk7z> Message-ID: <559FD8B0.8060308@socal.rr.com> Thanks for that very graphic display at the link below, Dave.

For many reasons if you are chasing DXCC and have a K3 then RumLog or RumLogNG is the best choice. The ability to quickly determine the status of a DXCC country ( worked?, Modes? confirmed? Paper or Lotw?) is simply the best and integration with LoTW is great. One click and you're done. The DX Spots list is better than any logging program, Mac or Windows, for highlighting what spots you need for DXCC or for the Marathon. Then K3 control screen is well done and in RumLogNG there is also a P3 control screen that I use a lot.

To acquire a K3S that is configured similarly to my K3, I'd have to spend almost $4600, and to do all that currently available upgrades, I will have about $3600 in my K3. This leaves $1000 difference. We'll see how much the KIO3B and DSP boards cost, but to me, I'm not sure I can justify the cost difference for a couple of attenuator steps, a slightly better noise floor, and a nice bezel, especially since I'll lose a few bucks if I try to sell my K3. In fact, I'd like to see an upgraded "K3" marked black bezel for current K3 owners. Its does look nice, and would look nicer with black screws... 73, Scott N9AA On 7/10/15 9:07 AM, Bill wrote: > After reading all the posts about the improvements that can be made > now (and in the near future) to the K3, I find it difficult to decide > between a new K3S or to add the upgrades as they become available.

After updating the synthesizer(s) and replacing the KVX3/KXV3A with the KXV3B, if one updates the KBPF3 "general coverage" bandpass filter board(s) and adds the regulator bypass capacitors, there are only four remaining "performance" upgrades between an updated K3 and a K3S - all of which are minor: 1) modified bias in the speaker amplifier *driver* (not the amp itself) for improved linearity. This does not affect the power output or frequency response. 2) 5/10/15 dB stepping on the *main receiver* attenuator (this does not affect the KRX3 which remains at 0/10dB) 3) improved isolation on the main RF board due to a change from two to four layer construction. The difference is probably not measurable on the air. 4) a change in RF output devices in the KPA3 - difference TBD. The other change is the KIO3B which provides the option of an internal USB interface for radio control and USB CODEC ("sound card"). A traditional RS-232 interface is more flexible and a *high quality* external sound card or *well designed* audio interface *may* provide a somewhat lower noise floor (better SNR/dynamic range). Most users will probably not notice a performance boost unless they are using one of the notoriously "dirty" (cheap) amateur products. 73, ...

There is no doubt that the K3S is an improved radio, but whether those improvements are worth the associated costs in selling a K3 and buying a K3S is open for debate, given that many of the most important improvements are available as upgrades to the K3. I think this actually falls in line with what Eric and Wayne have always promised: There would be an upgrade path available to current K3 owners whenever a new radio became available. This seems to be the case. While K3 owners cannot upgrade directly to make their current K3 a K3S, the updates available get us pretty close. And that's fair enough, in my mind anyway. 73, Scott N9AA On 7/10/15 3:26 PM, Joe Subich, W4TV wrote: > > The other change is the KIO3B which provides the option of an > internal USB interface for radio control and USB CODEC ("sound > card").

For these bands you would have the option (for each band) of Preamp off, Preamp 1, or Preamp 2. Preamp 2 is on the KXV3B and is really an LNA (low noise amp) with somewhat higher gain and lower noise figures than the original K3's preamp (Preamp 1). - Due to its four-layer design, the KXV3B introduces less noise than the KXV3A. Note that both are ultra-quiet, but the KXV3B more so. With the proper firmware loaded on your K3, the KXV3B is a functional replacement for the KXV3A with improvements as noted above. The KXV3B was developed for use in the K3S and as an upgrade to the K3. 73, matt zilmer W6NIA On Fri, 10 Jul 2015 23:45:10 +0100, you wrote: >I purchased the KXV3A kit earlier this year, but for various reasons, I haven?t gotten round to installing it in my K3 yet! > >I see references to a KXV3B kit, but can?t seem to find what the differences are and whether there?s an upgrade path from ?A? to ?B?. > >Looking on the Elecraft website at the orders pages, only the KXV3B appears to be on offer now.

Yes, you need to change both boards if your K3 has the KRX3 installed - it will not work right with mixed synth boards. I would advocate changing the synth boards in both your local K3 and the remote - unless you never use your local K3 standalone. 73, Don W3FPR On 7/10/2015 9:21 PM, John via Elecraft wrote: > I am using two K3's in my remote system.

The carrier or one of the transmitted tones? What happens if you are not in either Split or Diversity - reception on the main receiver only (turn the SUB off)? What the P3 should show is the WWV carrier at 10.000 MHz, but the K3 audio will not be receiving that carrier in SSB mode. The K3 will receive one or the other of the sidebands, so the green band will be offset from the center indicating the sideband that is being received. The center of the green band should be offset by the amount of shift you have dialed in on the SHIFT/WIDTH knobs. If you are using LO/HI CUT, the amount it should be shifted will be the center of the difference between the Hi and Lo frequencies. Normally when you listen to an SSB station, the K3 frequency will indicate the suppressed carrier frequency - but WWV is an AM station, and when tuned properly to listen to the audio, you will not hear the carrier (it is out of the receive passband), but the P3 will still indicate the carrier of the WWV signal. 73, Don W3FPR On 7/11/2015 1:56 PM, rick.ag6ay at gmail.com wrote: > Hi all > > I have a very odd thing happening in diversity mode after installing the new > VFO's.

For example, if your main RX has a 2.8 KHz filter installed and you are listening within that bandwidth, be sure that your sub-RX is ALSO using a 2.8 KHz filter. If not, you'll experience the frequency shift. I don't claim to know why; only that I've observed that behavior here with the new Synths. This shift did not occur with the original Synth cards. I don't consider it to be a problem; it just means that I need to get another filter for the sub-receiver so that the filter complement of the sub-RX matches that of the main RX, (which is supposed to be the case when using diversity reception anyway). If you have a bandwidth where you know that both the main RX and sub-RX are using the SAME filter bandwidth, use that bandwidth and see if the issue still occurs. If it does, then the issue is being caused by something other than what I mentioned above. 73, Dale WA8SRA > Hi all > > I have a very odd thing happening in diversity mode after installing the > new > VFO's.

The HOA appears to be quite benign and benevolent, I'm planning on a flag pole [with a flag on good wx days] in the backyard, with an insulator at the bottom where I'd like to remote my KAT500 in a wx-proof box. I'll probably power it through the same conduit that carries the coax. It would not be connected to the K3 of course. I'd like to run it in MAN mode as I do now. If I start in AUTO and step through all the band segments, will it learn the settings, and just recall them as soon as it senses RF? 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From w3fpr at embarqmail.com Sat Jul 11 18:03:02 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Sat, 11 Jul 2015 18:03:02 -0400 Subject: [Elecraft] K2 Alignment In-Reply-To: References: Message-ID: <55A19296.90103@embarqmail.com> Tom, Your limited BFO range will only be a problem when aligning the IF filters. If you find you cannot align the filters properly, then you will have to correct that problem, but it may be a case that you have a marginal solder connection somewhere in the BFO area and re-flowing the soldering will give you a wider range. Look at the RF Board schematic sheet 2 in the lower right corner to identify the components involved with the BFO. Typically the K2 does not drift but a few Hz after being given a bit of a warmup period (10 or 15 minutes). Proper dial calibration and drift are 2 different things. Drift is the frequency change over a short period of time, such as a single operating session (usually do to temperature changes). Dial Calibration can change over time, but typically does not vary much because the calibration data is contained in EEPROM and does not depend on any realtime reference oscillator for accuracy and consistency. If your situation is really drift (by my definition above), then I need to ask how old is your K2 (serial number please). If it is SN 3000 or below, does it have the A to B upgrades as well as the other Elecraft mods installed. There are 2 mod kits that are important for temperature stability - the BFOMDKT and E850138 (the PLL temperature compensation mod - so called "thermistor mod"). Look at the BFO inductor L33 on the bottom of the RF board - if it has many turns of fine wire and is held in place by a 1/8 watt resistor, then you have the BFOMDKT installed. Then look on the top of the RF board on the left side near the Control Board for RP3 (it may be under the KDSP2 or KAF2 if you have those options). If you see a small board with resistors on it in the RP3 location, you have the "thermistor mod" installed. Especially since you have the K2/100, if either of those mods are missing, I suggest you install them. In addition, if your K2 is below SN 3000, you may want to consider doing the entire set of A to B upgrade mods (I recommend it). Once you have checked those mods, go on with your calibration and alignment process. For the K2 Dial Calibration and filter alignment, I suggest you use Spectrogram or another audio spectrum analyzer for the best results. See my webpage www.w3fpr.com article on K2 Dial Calibration. OK, I have given you more information at one time than you may have wanted. However, it is all related to dial calibration and drift (again, two different things). Work through it one step at a time, and if you have questions as you go along, please ask. 73, Don W3FPR On 7/11/2015 1:48 PM, Tom Field wrote: > I've been using my K2/100 for a couple of years, and have been very > satisfied.

I'll look into that, and if it's a firmware issue, I'll get it fixed ASAP. What filters do you have installed?

I will try for a compiled response since I had so many responses! "what exactly are you zero beating? The WWV carrier ... well ok I'm not exactly zero beating in the proper sense. By tuning the K3 through the 10.000 MHz WWV AM station using SSB mode with Lo = 0.00, I can quickly confirm the extremely low frequency audio is indeed the carrier and that it 'goes through zero Hz" at 10.000 MHz. Again, this is not a proper zero beat but it's close enough for Gov't work :) "What happens if you are not in either Split or Diversity" WWV 10 MHz carrier 'zero beatsz at exactly 10.000 MHz "If you are using LO/HI CUT ..." and other comments about band pass ...

I very well could have set Hi = 3.0 and that would set up the scenario you mentioned. Cool. That should not take long to try. However, I don't recall an absolute requirement for filter parity between main and sub rx as the firmware should select the largest available even when desired BW > filter BW. I know diversity quality would be impacted if the filters were not identical but I would not have expected a -freq- shift like I observed. OK I just tried WWV with Lo = 0.00 and Hi = 3.0 on A and B VFO (using BSET). I am in USB Diversity mode tuned to WWV 10.000 MHz. WWV sounds fine XFIL = FL2 (6 kHz) <-- yep. this is expected. I hit BSET XFIL = FL3 (2.8 kHz) <-- Actually this is what I expected since this is the widest filter on RX B where Main: 1=15k, 2=6k, 3=2.8k, 4=2.1k, 5=0.4k Sub: 1=0.0, 2=0.0, 3=2.8k, 4=2.1k, 5=0.4k ... and no mysterious frequency shift. I still can't figure out where the 1.5 kHz shift came from but I'm grateful it is gone!

I just used diversity on 20M in IARU and it is obvious that - RX A is on freq - RX B is 1.5 kHz low When I use BSET I see - RX A XFIL = FL2 (6 kHz) I hit BSET - RX B XFIL = FL3 (2.8 kHz) I then adjusted Hi from 3.0 kHz to 2.8 kHz. Lo! The instant the displayed RX A XFIL changed from FL2 (6 kHz) to FL3 (2.8 kHz) I magically heard the RX B audio shift magically by 1.5 kHz to align with RX B audio. Wow. That was -very- interesting to replicate! Thanks for poking at this with me. *Now that I understand it, I can work around it. Much, much thanks!* Wayne I think we have an honest live one for you now!

First, I'd like to invite you to our 81st annual Hamfest. (see http://ham-ham.org for more details). I've made some efforts to contact Amateur Radio manufactures in an attempt to put together a "Radio Brag" presentation for our Hamfest (an opportunity to present their radios to potential customers). Because our Hamfest wouldn't warrant the manufactures to come themselves, I had asked if they had any local hams willing to come and tells us their experience with their own radio. The response has been slow. So, I'm asking if their is anyone willing to give a "live review" of their newer Elecraft radio. Nothing fancy, just what you like about the radio and your experiences with it and answer any questions. If we can muster at least three manufactures radio-users to commit, we'll set it up. Here's the deal: The presenter gets free admission (a single stub ticket). They'll have a table (which we'd like manned between 10AM and noon). We'll supply 115 VAC, a sound system, dummy load and workable antenna (for the presentation portion of the show). You have to supply the radio! We hope to get people interested in Elecraft (and other manufactures) to have an opportunity to see and hear what Elecraft is all about.

In the last six weeks of intermittent operation, I've made about 175 JT65 and JT9 QSOs, mainly on 20m. Approx 20% of contacts have been JT9. I'm usually running 10W into a fixed (about 60 degrees) 20m dipole about 15ft off the ground (HOA issues). I've been using PSKreporter to track progress. I must conclude from these results that after temperature compensation the KX3 is doing a good job with both modes. Even though I'm using a unmodified SignaLink, I can hear many more stations than I can work. Of the 175 contacts, so far 34 different US states. Countries are a little harder to come by as there's usually to much competition from bigger signals. All this with S7 noise on 20m! 73's Gary K6YOA From droese at necg.de Sun Jul 12 12:49:34 2015 From: droese at necg.de (=?windows-1252?Q?Oliver_Dr=F6se?=) Date: Sun, 12 Jul 2015 18:49:34 +0200 Subject: [Elecraft] Filters & KRX3 for sale In-Reply-To: <55932497.5000601@necg.de> References: <55932497.5000601@necg.de> Message-ID: <55A29A9E.8030102@necg.de> All things have been spoken for except one of the 400 HZ filters.

Could not the technique used for that situation be applied when the K3 knows the filter widths are different? Note I fully grasp diversity is degraded when the filters differ; I am just wondering if the frequency shift effect can be compensated for even when diversity is degraded.

The filter centers do not match, and that leads to calculations of the filter centers which are different - the result is that the K3 is 'confused' and the offset is the result. Use the same filters in both the main and the sub when using diversity. 73, Don W3FPR On 7/12/2015 10:13 AM, rick.ag6ay at gmail.com wrote: > post starts now ... > > I can better explain and reproduce the issue now.

Remember that all of his professional work is for VHF/UHF, where there is FAR less possibility of interference to and from the vehicle's on-board electronics. He is unlikely to know about using ferrite chokes to avoid problems on HF, and he won't know that multiple turns are needed. > Plan to meet him next week.

Yes. Do NOT use the chassis as a return. Do NOT bond the radio or the power amp to the car. > , in-line fusing everywhere. . . . DC wiring shielded? No, but use twisted pair. Buy black and white #10, put it in a drill and twist it. Make the cable long enough that you can wind multiple turns through a ferrite core, following the guidelines in k9yc.com/RFI-Ham.pdf Place the choke near the battery. > How about the control lines from the KX3 in the cockpit to the > KPA in the rear cargo space? Elecraft has connectorized for CAT5, which, if each signal is on a pair, offers good noise rejection. Add a ferrite choke to these cables. > Any special considerations? What else should I be sure to have done? Use a ferrite choke on the coax as close as possible to the antenna. DO bond the coax shield to the vehicle at the antenna -- that's your counterpoise -- and make sure that everything in the path is bonded. Example -- in an S80 Volvo I used to own, I used a license plate mount. I had to bond between the mount and the trunk lid, and also around the trunk hinges. More bonding would have improved both TX and RX, but I never got around to doing it. > SSB - I have never used either the KX3 or the K3 on anything other than > CW.

The laws of physics don't change between rigs. Use the same settings for TXEQ that I posted for the K3 -- max cut of the three lowest bands, cut 6 dB on the 4th band. Depending on the mic and your voice, you might want more cut on the 4th band, and you might want a bit of boost on the top two bands, but not more than 6 dB. Because the KX3 audio amp is intentionally designed to minimize current draw for backpacking, it is good to use the same settings for RXEQ. This will maximize the power available for speech. > And despite the critique posted > here recently, I have the Heil Pro headset that Elecraft sold with the > rig. But I don?t want a headset while I?m driving, right? For county hunters, you might want to try to find places you can park. Hilltop locations can greatly improve your signal, and being parked allows you to wear a headset. Also, don't rule out CW, which will greatly improve your range. I've done a LOT of CW mobile, even when driving through Chicago rush hour traffic! I'm a leftie, so I put the paddle on top of the compartment between the two seats. > So - what?s a good mike? See comments in previous threads. Almost any good communications mic can be made to work fine by simply wiring it correctly. > And should I try to get the KX3 audio output through the car?s audio system I would be cautious about that -- you could open up a can of worms with RFI or noise. > (it?s an old Bose), or buy a separate external speaker and > mount it somewhere? Many years ago, I found some little cube speakers at a hamfest, and bought ten of them. I recently mounted a pair of them to the headrest for use with my FM rig. That MIGHT be loud enough. Try the passive speaker first if you can find one, use the amplified speaker as a last resort -- again, that can of worms with noise from the vehicle's electrical system. One good alternative, if you can find them, are the battery-powered speakers that used to be sold for use with Walkman-style products. This eliminates the need for connection to the vehicle for power. > What else am I not thinking of . . ? Watch out for QRM TO your vehicle's computers.

Assigning a requirement that that all should behave normally when the receivers are NOT identical seems unfair among other things. Do we really want the time and cost of Wayne's research spent trying to fake two dissimilar receivers to behave alike in diversity? Why do you want diversity beyond 2.8 kHz bandwidth? For AM? If so don't you really need identical filters for your preferred reception method for AM? For what it's worth I use SSB reception (including a pair of identical SSB filters 2.7 or 1.8) on AM for best diversity reception of weak AM, and that includes music if it's far enough out of the noise. 73, Guy K2AV On Sunday, July 12, 2015, rick.ag6ay at gmail.com wrote: > I sure hope not! > > Actually that raises a good question. > > Wayne, is this effect something you consider a bug?

It is not that I want diversity beyond 2.8 kHz, I just accidentally did and the current side effect of shifting the RX B passband caught be by surprise as I don't recall this experience prior to updating the Synth boards. I get that diversity means identical paths but I do wonder if the freq shift might be compensated for even when different filters are used for no other reason than that's all that's available to the K3. Yes that would mean diversity is degraded until one reduces BW down to where the filters are identical. I suggest that might be better than hearing everything in your right ear shift suddenly. It's not a demand. It's only a thought as I thought it worked that way before I upgraded the Synths.

I need to monitor the FSK441 calling frequency?of 144.370 on my K3 / tvtr combo. Then, when I see on the ON4KST chatroom that the other station is monitoring say 144.380 to be able to set the rig up to Tx on that frequency automatically when I?Tx on?FSK441. Then, return to the Rx frequency when FSK441 automatically goes to Rx. I don't want to be manually switching VFOs as per what it seems to be saying in Freds book I've gone round and around in circles and need an idiots guide with real examples to get to grips with the issue. In this respect EME is far easier - no split working which is one reason I've steered clear of FSK441 but I feel I'm missing out and need all the assistance I can get in obtaining DXCC on 2m!!!

Wayne will likely correct me if I am wrong. With the old synths in diversity mode, there was one synth driving the main RX and the other driving the subRX. With filters being different (2.8kHz for one and 6kHz the other), each receiver could calculate the filter center and apply a correction to its synthesizer, and all would be 'well'. With the new synthesizers, in diversity mode, only the synth for the main is used to drive both receivers. This phase locks the two quite nicely, but if the two receivers are using different width filters, the calculation for the filter center cannot be correct for both filter widths. 73, Don W3FPR On 7/12/2015 3:11 PM, rick.ag6ay at gmail.com wrote: > I get that diversity means identical paths but I do wonder if the freq shift > might be compensated for even when different filters are used for no other > reason than that's all that's available to the K3.

I doubt very much that any MFJ tuner will have much success in matching a 15 or 20:1 SWR which a vertical like that will have on some bands. Here is a couple of pictures of my installation which has survived 2 CNY winters without any degradation: http://ab2tc.com/IMG_0181.jpg http://ab2tc.com/IMG_0179.jpg My G5RV is about 15:1 on 10m. I have a resonant 10m dipole up at greater height than the G5RV but the G5RV almost always wins. Of course the G5RV has many deep nulls but outside of those it's always the better antenna so the loss in the tuner, even at that SWR, can not be that bad. The installation is straight forward. There is no AUX cable connection to the K3. I control the tuner using the PC utility through a WiFi serial server. I used an Ethernet serial server for a while, but it was much worse for birdies and I didn't like the need foe another cable to the site. Right now, just power and one coax. BTW the gray box is a switch box for 4 more antennas controlled by the 2nd channel on the serial server. Feel free to contact me on E-mail. My address is good on QRZ.com. I have many previous postings on here about this installation so a search for AB2TC will reveal those. Some older picture links no longer work because my server address has changed. Just replace the server name, whatever it is, with ab2tc.com/ and it should work AB2TC - Knut Jeff Cochrane - VK4XA wrote > Fred, > Wouldn't it be easier to just buy something like one of MFJ's remote > tuners that are built exactly for the job you want your KAT500 to do? > If I had a KAT500, I don't think I'd want my $700 Elecraft auto tuner left > outside, where it was never meant to be.

If you want to operate diversity in AM you will need one of the wider filters. If you're not in AM, keep the bandwidth below 2.8 KHz and there will be no frequency shift in the sub RX. I don't see how the compensation for 5 pole filters will work with the widely divergent bandwidth - particularly since the 8 pole filters do not have a frequency offset. 73, ...

That arrow tells you which VFO will be used for transmit. Turn the VFO B knob to the frequency you want to use for transmit. If you have the subRX installed you can turn it on and listen to the transmit frequency in one ear. Without the subRX, hold the REV button to temporarily listen to your transmit frequency. Release the button to hear your receive frequency again. That is all there is to it. If you now re-read the manual or the Cady book, you may understand it better. 73, Don W3FPR On 7/12/2015 3:30 PM, PETER HUTCHISON wrote: > Yes - I have read some of the previous threads but am still confused re Split working... > I need to monitor the FSK441 calling frequency of 144.370 on my K3 / tvtr combo.

Direct DC to the battery with both sides fused at 30 Amps. 2. Have found my old Hustler to be very inefficient. Have tried several other antennas but use a budipole dipole from a fixed most of the time when I want to maximize my signal. 3. For the microphone I have found Elecraft's H3 hand microphone to get good audio reports when adjusted per Elecrafts instructions. 4. One last thing use Cat 5 or 6 shielded cable for the control cable between the KX3 and the amp grounded only at the amp to avoid problems.

So my question is what physical size is the 220mfd solid polymer cap used to bypass the zener in the BPF mods (enabling reception down to 500KHz). It would appear to be a 16v component but I guess 10v would suffice. Clearly it would need to be small enough to fit in the available space but without taking my K3 apart I cannot measure that readily, so if someone has one they could measure for me (diameter is critical as it lays on its side), that would be grand. >Andy G4HUE >K3 6990, P3 2493, KAT500 1245, KPA500 2102 >______________________________________________________________ >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 mzilmer at roadrunner.com Matt Zilmer, W6NIA -- "Always store beer in a dark place." -R.

The ALC was appropriately set based on information Don provided several weeks ago but it was the first thing I checked. The mic level was set for 5 bars ALC. After the last problem, I checked all connections and setting and everything seemed correct. The PSU was stable at 13.4V and VSWR sweep on antenna did not show any problems. I connected rig to a power meter and dummy load and brought up all the s/w. Things started working again. I then put the radio through a 12 cycle CQ sequence at 10W. Again all good. I reconnected the antenna and started attempting to QSOs. PSKreporter showed I was getting out and then I worked two QSOs without issue. However, on the third QSO, on the second transmission block the TX power collapsed (KX3 TX light still red) I think midway into the transmission - I halted TX on WSJT-X. I tried the tune function on WSJT-X and while the KX3 TX indicator comes on there was no TX power. ALC shows zero bars. Thus, I would have to conclude the problem is an intermittent behavior rather than setup issue. It seems to me the KX3 TX is shutting down in response to some fault condition. PA temp is well below max, and no other error messages are observed. Unlike when the unit powers down due to high temp, the power setting remains at 10W. ALC shows zero bars. While trying the tune function on WSJT-X after fault condition, I increase mic gain and ALC bars start to briefly show and TX power briefly flickers on power meter. However, within a second so the ALC bars drop back to zero and so does the power. Increasing the mic gain again results in similar behavior. I switch all equipment off and call it a night. This morning, I bring anything up again and the KX3 will not radiate power in digital mode albeit the TX light is ON. Transmitting in FM the radio seems to be working! Again, thoughts would be greatly appreciated. 73's Gary K6YOA That is a typical behavior when the KX3 (or K2 or K3) is not provided with sufficient audio drive. It "power hunts". Increase the soundcard audio output and/or the mic level to produce 4 bars with the 5th bar flickering on the ALC meter. Set the power level with the power knob. Attempting to control the power level with the audio drive will result in failure. 73, Don W3FPR On 7/12/2015 8:39 PM, Gary Hawkins wrote: I'm seeing a odd problem working digital today with my KX3.

I suggest a Common Mode choke on and at the output of the radio. Perhaps a fault with a antenna or coax jumper or associated connector. 73 Bob, K4TAX On 7/13/2015 11:35 AM, Gary Hawkins wrote: > Just as background, this digital setup has been working successfully > for several weeks and as I mentioned in another post I've recently had > over 170 contacts in both JT65/JT9 running 5 or 10W (my KX3 has 3rd > third party heatsink).

It could be as simple as an intermittent audio cable connection or a fault in the audio wire. If you have an audio amplifier available (like one of those used with an iPOD or similar), plug the cable that you normally plug into the KX3 and see if you have the digital tones coming out of the Signalink and that audio cable - you will hear audio only in the left channel, the Signalink does not use the right channel. Since you say FM appears to be working, that sounds like the KX3 mic audio is not at fault. If everything works into a dummy load, check your antenna system to determine if the cause may be RF in the shack that is bothering your Signalink. 73, Don W3FPR On 7/13/2015 12:35 PM, Gary Hawkins wrote: > > Thus, I would have to conclude the problem is an intermittent behavior > rather than setup issue.

The VFO-B display of menu status said ERR (probably battery ERR but I forgot to write it down). I took all the batteries out, 2700 mAH NiMH cells, and tested the voltage of each one using DVM (so, no current draw test). They all tested about 1.38 volts per cell which seems to be about right. I put them back in to the KX3 but they would not power the KX3 ? attempting to turn on the KX3 failed. I took those batteries out of the KX3 and put in another spare set of batteries and they powered up the KX3 without problem. Since these batteries are fairly new and maybe only have about two dozen recharge cycles, I am curious as to what the problem might be and whether it is a problem I can test (more than DVM voltage test). Does anyone have any advice. I would hate to junk all 8 of them. Another question: does the life of a NiMH battery change based on whether a 4 hour or 8 hour charging cycle is chosen?

Does your KX3 operate in voice modes when using the microphone? If so, there is not a likely problem with the KX3. Investigate your computer sound card levels to assure that you have adequate audio levels going to the KX3. You should drive the ALC meter on the KX3 to at least 4 bars with the 5th bar flickering. Those first 4 bars are to used as an indicator of the audio drive level. Ignore the web advice for other transceivers which tell you to control the power level with the audio input level - that will not work well with the KX3. Adjust the audio (using the soundcard controls in the computer and the KX3 mic level) to achieve 4 to 5 bars on the ALC meter and adjust the power level using the power knob. If you have questions about whether the computer soundcard is producing audio, remove the cable from the KX3 mic input and plug it into one of those audio amplifiers intended for use with iPOD or other devices -- do you hear the PSK31 tones being sent. If not, look to your computer and soundcard settings until you can control that audio output. Because the computer/soundcard combinations can be so varied and computer/soundcard related, no single answer can be provided. If you can give specific computer and soundcard information, perhaps someone with a similar setup can help you. 73, Don W3FPR On 7/13/2015 9:20 PM, Michael Rudolph wrote: > All, > > > > I have my KX3 connected to a computer and am running FLdigi.

This is ubuntu 12.04LTS running on a standard issue Dell PC platform. Running the Editor from a shell: in ~/.wine/drive_c/Program Files/Elecraft/Elecraft FrequencyMemoryEditor, with a command line of ./FrequencyMemoryEditor.exe. The program executes and shows a GUI. The K3 serial port is the Elecraft USB/Serial adapter for the K3. This uses a DE9 connector at the K3 end. On this linux, the device is enumerated as /dev/ttyUSB0. I've also made the device accessible using a symbolic link (ln -s /dev/ttyUSB0 COM1), but no joy using either device or link. The problem here is a little different from yours, but it's still a problem. Even though the GUI loads and allows execution of the Read All from Xcvr button, the program never receives a valid response (or at least it's not interpreted that way). I checked at the four baud rates used, and the Editor is sending a ';' to determine basic connectivity. But it's not getting a good response, no matter which K3 CONFIG:RS322 bps rate is set up. Using the Elecraft USB/Serial adapter, I can see the K3 responding via the LEDs inside the housing, and confirmed a ';' going to the K3 using a null modem cable. So anyway, that's me blowing off steam and it doesn't address the problem you have. Sorry for the diversion. I'd suggest you try executing the Editor not from the desktop icon, but from the command line as described above. This is in case there is some icon / shortcut parameter that doesn't allow the program to start. You can fix the icon Properties later. If the program runs (as above) maybe we can compare notes and get something going for you. Unless there are a vast number of linux users, we might want to do this off-list, if you're interested at all. 73, matt W6NIA On Tue, 14 Jul 2015 20:00:14 -0400, you wrote: >Don has it right regarding the Utility.

Pierfrancesco Caci IK5PVX joined in later and we spent some time decoding binary returns after changing a single setting. We made good progress, but it's tedious and we instead returned to on-air pursuits! Turns out I don't use the memories too often anyway. I have other tiny C programs more useful to me. It's possible to reverse engineer, though I never went so far as to write into memory for fear of doing something regrettable. :-) 73, Mike ab3ap Sample output from seconds ago using the -b (brief summary) option.

On page 46, the crystal filter setup page, it states that you should enter a gain of 1-2 db for the 400 Hz filter. I have a 400 Hz filter and I have entered 2 db. I searched the PDF version of the K3 manual for offset and found on page 79 that it states that all 8 pole filters have zero offset. A note to this effect should have probably been added to page 46. 73, Mike K2MK I purchased a 400Hz 8 pole (Inrad) filter and installed it in my K3 yesterday.

What I do is adjust the filter gains so that there will be no change in signal strength when switching filters. You can do this by ear if you turn off the AGC, or you can use the K3's DBV function if you are a perfectionist.

I have seen no changes at all.. but I am not a real QRQ op. I usually run about 28 wpm... sometimes about 32, and very rarely a bit higher than that. I did put in the new Synth boards, and have verified that QSK is now silky smooth up to speeds much higher than I dare try to operate. Best of luck getting everything to play the way you want it to.

And there was another fascinating article there about how they use Reed-Solomon error correcting codes to compensate for the inevitable bit errors and reduce the need for retransmission (and now using the same RS code for DNA data storage, very cool stuff.) Nothing about the path loss, but knowing the data rate is so low, and that the RS code is probably good for a considerable error burst of several bits, that should at least give you a sense of what the loss might be! 73 jeff wk6i On Thu, Jul 16, 2015 at 11:10 AM, wrote: > Heard last night on Nova program that the transmitter on the Pathfinder > Pluto probe was 10 watts.

Just one of the benefits is that the new synthesizer does state changes way faster than the old syn. RX/TX state changes are what QSK is all about. Besides the new syn, there have been a lot of changes to QSK, some number of varieties of QSK now, since the olden days of firmware version 3.xx. Way lotsa stuff under the bridge since then. Includes some very significant improvements to AGC and K3 performance listening to a pile-up.

The formulas are well known. Perhaps less known is the rest of the story. The probe is using its high gain (dish) antenna, perhaps 20 db. Since it is a dish antenna it must be aimed! The probe is programmed to aim its antennas periodically since it can not be commanded to turn its antenna. Back at this end, the Goldstone antennas have about 60db gain with cryogenically cooled noise figures of <1. I'm guessing the receiver sensitivity at around ---150 to -170 dbm using a very narrow bandwidth and correlation techniques similar to what is used on GPS receivers. Transmission flight of path is > six hours. 73 Fred, AE6QL -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of ac5p at sbcglobal.net Sent: Thursday, July 16, 2015 11:10 AM To: Elecraft Reflector Subject: [Elecraft] QRP signals from Pathfinder probe (off topic) Heard last night on Nova program that the transmitter on the Pathfinder Pluto probe was 10 watts.

E-mail 101 allows you to mark the senders of such nonsense as spamers or junk. Once marked, future submissions from these purveyors of trash get routed to the junk folder. That saves you unwanted delete key activity. Of course one persons trash might be an others treasure. Suggest use with caution.

What I like most about it is that I can design filters that either destroy or accept emails based on filters that I can make. It usually works very well, but this list has mutated into a very hard to filter list. In fact most email applications have that feature. The solution I propose is that each subject line that is a true Elecraft product post begin with the name of the Elecraft product in question. Here are some examples: K3, K3S, P3, KPA500, KAT500, K2, KRC2, KX3 or whatever. If those of you who only want to talk about Elecraft products would do that it would be easy to filter out off topic subjects, even if you did it by hand. The trouble with adding "On-Topic" is that it doesn't specify which product. For instance: I'm not interested in K2 or KX3 topics, because I don't own either of them and I am not considering buying one of the two (at this time), but I AM interested in the products I own and plan to own in the future. What say those of you who are tired of off topic posts?

Other numbers of interest is downlink f=8.438 GHz, downlink antenna (2.1m dish) gain is +42 dB and Tx power is 12-15w (say +41 dBm); spacecraft EIRP = 42+41 = +83 dBm. -303.5+83 = -220.5 dBm. Add gain of ground antenna +73 dBi (70m dish): -220.5+73 = -146.5 dBm Your K3 MDS is -145 dBm at B=500 Hz Just for grins I substituted my dish (4.9m) with gain 49.7 dBi and signal to my Rx would be -220.5+49.7 = -170.8 dBm If I use a really narrow bandwidth I might see a signal trace using something like spectravue sw. A ham has received Pioneer's signal in such a manner when it was beyond Pluto's orbit.

You can do this by ear if you turn off the AGC, or you can use the K3's DBV function if you are a perfectionist.

Otherwise You will notice big attenuation when You will switching thru the BW down to 400/250Hz filters. As I do not like to get attenuation during weak signals hunting when going down in BW I did it the same as Vic mentioned and it is working nice for me specialy when I am spending most of the time on 150Hz BW on LB. In my case I found the 400Hz/4dB and 250Hz/5dB as good solution. 73 - Petr, OK1RP ----- http://ok1rp.blogspot.com -- View this message in context: http://elecraft.365791.n2.nabble.com/Another-one-of-those-filter-questions-tp7604956p7605005.html Sent from the Elecraft mailing list archive at Nabble.com.

So at over 36 hours round trip light travel time (0.002 light years range), Voyager 1 scores a lot more points compared with less than 9 hours for the Pluto probe which has the same power, but with 12dB less free space path loss. -- David Woolley Owner K2 06123 On 16/07/15 20:46, Brian D wrote: > Voyager is still going strong many times further away than Pluto, 315w to a > 3.7m dish. from over 19 billion KM.

So long as you can set the filters properly, I wouldn?t worry about the BFO range. When I added the RTTY mode and set my filters for 1500 Hz center frequency, I had to pad the BFO with a small capacitor to get enough range.

Yes. We've gone through several rounds of "alpha" testing. Assuming the latest version (01.44) looks good we should shortly be releasing it for beta test. In addition to the TX monitor, it also includes several other new features: - New 7x11 font size option. - Allows separate control of the waterfall on the external monitor. - Supports preamp 2 in the KXV3B (which is standard on the K3S).

However, I run a separate, parallel cable from the PWRgate output to the K3 to keep Voltage drop to a minimum. The K3 has its own circuit breaker. I use the RIG runner for 12VDC accessories. The PWRgate has come in handy when the power supply or commercial AC dropped out in the middle of a QSO. During Field Day several years ago someone hit the power supply switch accidentally and we kept operating on 20 SSB. Some time later, the CW Team Captain came by to ask if we were doing something different. I checked everything and noted the battery Voltage was down to 10.5 Volts! That increased the K3 PA IMD significantly which impacted the 20 CW operation a couple of hundred yards across the park. (This is the only one of two times we have had inter-station QRM. The second was a defective K2 PA.) I now use an AC power indicator (AC-powered clock) so ops know if something in the AC power system failed.

It even has trouble tuning up a 50 ohm dummy load on these bands. My normal setup is a 10W K2 with a KAT2, connected on the ANT 1 port to the AUX RF port of the KAT100 (mounted in an EC2 case with the KPA100). This is internally connected to the KPA100. The RF out from the KPA100 is then connected to the RF IN on the KAT100. ANT 1 is connected to a DX-CC and ANT 2 is connected to an 80M Carolina Windom. The first signs of trouble started when the SWR LEDs only lit intermittently. The ANTENNA and PWR RANGE LEDs lit and operated correctly. Gradually I stared seeing higher and higher SWR readings. In order to narrow down the issue, I removed the KPA100 from the setup by connecting the KAT2 ANT 1 port directly to the KAT100 RF IN. I disconnected the power from the KPA100 and independently powered the KAT100. I removed the Windom from ANT 2 and connected a 50 ohm dummy load to see how the tuning compared with the antenna and the dummy load. On 80M the dummy load gets 3:1 SWR with the DX-CC tuning up the same. 60M gets 2.3:1 for both. 40M gets 1.2 for the dummy load and 3:1 for the DX-CC. 30M and up seem to tune ok. I tried doing the troubleshooting steps in the manual, starting with ATU INIT. I scrolled through L0-L8 and C0-C8 and N1-N2 and the relays functioned for each. I tried doing the individual test for the inductors and relays, but there was no change in SWR with multiple components, so either I was doing it wrong, or the fault is bigger than a single component. I've tried to be as detailed as possible here, so any help is appreciated, and if there are any suggestions or any other info required please let me know. I'd like to get this back on the air as its my only radio! -- View this message in context: http://elecraft.365791.n2.nabble.com/KAT100-Tuning-Failure-tp7605018.html Sent from the Elecraft mailing list archive at Nabble.com.

The fact that you had the KPA100 partly in the path during your tests could create invalid observations. Use a dummy load for testing rather than an antenna. If you are getting funny SWR LED indications, the first suspect is D1 and D2 in the KAT100. Those are 1N5711 diodes, and if you have some in your parts supply, I would just replace them. I know it is a 'bear' to get to the solder side of the board when mounted in the EC2 enclosure, so see if there is enough lead length above the board to break the diodes and solder new ones in their place. You would get a better picture of the operation of the KAT100 wattmeter if you remove the KAT2 (just unplug it from the KIO2 AUX board). Then connect the KAT100 control cable and connect the K2 lower panel BNC to the KAT100 RF in. The KAT100 will then respond like the KAT2 normally does and in ATU CALP or CALS will show you the wattmeter readings - connect ANT1 to a dummy load for that test. It is advisable to connect an inline wattmeter between the KAT100 and the dummy load. If the internal wattmeter in the KAT100 is not functioning properly you will be able to calibrate it. 73, Don W3FPR On 7/17/2015 1:05 PM, JeremyJones wrote: > After many months of flawless operation, my KAT100 is starting to have > trouble tuning up, particularly on 40 and 80M.

I believe Bill is right and the QSK response does appear to be "slower". I normally run cw between 24 and 32 wpm. I did set CW QRQ to "on" and it does seem to switch "faster" but it's hard to quantify. Are there any other parameters to change for those of us who may not upgrade synthesizers? Tnx & 73, Gerry, W1GD Bill, There were some firmware changes made when the new synthesizers were introduced, and as I recall some of those changes involved QSK operation. Initial reports on the new synthesizers from users indicated that QSK was better. I have not seen any reports of QSK changes with the old synthesizers, but you may have "hit on something" - continue with the tests and tell us your results. 73, Don W3FPR On 7/16/2015 10:00 AM, Bill Stravinsky via Elecraft wrote: > When I first got my K3 in 2009 I thought the QSK was fabulous and used it every so often.

The equipment was PC running WSJT-X/HRD and an unmodified Signalink. WSJT-X was in transmit mode, I could hear the tones using the Mon connector on the Signalink, the audio tones were making it to the tip of the KX3 Mic connector (used amplified audio amp connected to tip and Ring 2), and yet the ALC would not go above zero and nothing was being transmitted by the KX3 no matter how I set up the mic level and various Windows/Signalink level controls. The identified problem - I was trying to transmit the test Tone and JT9 signal above the 2.8KHz upper bandwidth limit on the TX path of the KX3. No matter what you have the RX bandwidth set to, the maximum audio frequency that will go through the transmit chain is 2.8kHz. Hope this information saves someone else a lot of trial and error trying to determine what's gone wrong in their digital setup. 73's Gary K6YOA From vk5zm at bistre.net Sat Jul 18 01:50:16 2015 From: vk5zm at bistre.net (Matthew Cook) Date: Sat, 18 Jul 2015 15:20:16 +0930 Subject: [Elecraft] QRP signals from Pathfinder probe (off topic) In-Reply-To: <002b01d0bff9$666b89f0$33429dd0$@earthlink.net> References: <1921187144.1796752.1437070214091.JavaMail.yahoo@mail.yahoo.com> <002b01d0bff9$666b89f0$33429dd0$@earthlink.net> Message-ID: Lets not forget to include Madrid (Spain) and Canberra (Australia) in the above story, without them Goldstone cant do it on it's own.

When I upgraded to KSYN3As, I just replaced the coin cell while it was exposed with the sub-RX removed. At the time I replaced it, the cell was still going strong. Most of the CR series coin cells from around 2007 survive on the order of 10 years (shelf life). I think that this lifetime is generally longer now, but it varies by manufacturer. The cell I put in was rated to be good until 2025. I've used CR series cells in applications where they lasted 15 years. 73, matt W6NIA On Sat, 18 Jul 2015 18:28:49 +0100, you wrote: >In the next few days I?ll be taking apart my trusty K3 #266 to install K3SYNAs and do KBPF3 mods.

Likely irrelevant but the battery in my old TS-570DG was over 15 years old and still working when I replaced that battery a year ago.

Easiest would be a good active antenna, like the one available from Clifton Labs. Cheapest would be a multi-turn loop on a frame - search the web for homebrew designs. - it needs to be rotated, so that may make it a bit more complex, but it can have a narrow field of view which is good for eliminating noise. 73, Don W3FPR On 7/18/2015 2:52 PM, Phil Hystad wrote: > What is the cheapest easiest although effective RX antenna for listening to whatever below 500 KHz with a K3 and the new K3SYNA board? > > From lists at subich.com Sat Jul 18 16:11:49 2015 From: lists at subich.com (Joe Subich, W4TV) Date: Sat, 18 Jul 2015 16:11:49 -0400 Subject: [Elecraft] K3 Below 500 KHz RX Antenna In-Reply-To: <55AAA424.1020608@embarqmail.com> References: <5262E456-30D5-433E-9928-03580E6925E1@mac.com> <55AAA424.1020608@embarqmail.com> Message-ID: <55AAB305.6090703@subich.com> Actually, if you want cheap and effective look at the PA0RDT mini-whip active antenna: http://dl1dbc.net/SAQ/Mwhip/Article_pa0rdt-Mini-Whip_English.pdf The active antenna is relatively small and easy to build with no particularly expensive or difficult to find parts.

Want to know how it performs? Listen to the WEB-sdr at the Twente University made by PA3FWM. It uses such a mini-whip created by PA0RDT. I have one in my backyard, just two metres above the earth on an aluminium pole in a plastic box that formerly contained a HP printer power-supply. I regularly listen to the transmissions of the old Alexanderson alternator in Grimeton Sweden (callsign SAQ) that transmits on 17.2 kHz from time to time but also on all amateur bands up to 28 MHz although the upper limit is stated as 20 MHz. Incredible to be able to receive the alternator on a piece of PCB-copper clad of just a few square centimetres... Ok, SAQ's output is in the order of 200 kW. http://alexander.n.se/ The WEB-sdr can be found here: http://websdr.ewi.utwente.nl:8901/ Mind you it can be very busy ! On Android you should use Mozilla Firefox to listen to it. Info about the pa0rdt-Mini-Whip can be found here: http://pi4utr.nl/wp-content/uploads/download/pa0rdt_whip.pdf The document starts in English but continues in Dutch and Italian. 73, Peter - P0PJE Op 2015-07-18 20:52 schreef Phil Hystad: > What is the cheapest easiest although effective RX antenna for listening to whatever below 500 KHz with a K3 and the new K3SYNA board? > > Thanks, > > 73, phil, K7PEH > > P.S.

While the beverage is an excellent and directional receive antenna, it must be at least 1 wavelength long to be effective, longer is better. One needs at least 2 oriented at right angles to cover all directions. At 160 meters, 1 wavelength is about 530 feet - practical on some lots. To have a beverage on 100kHz would require a length of 9540 feet - almost 2 miles. Some ranchers in the US Southwest may have that kind of space available, but not on even a large lot owned by a typical ham. 73, Don W3FPR On 7/18/2015 4:32 PM, Milverton M.

I've used everything from a 10-meter coat hanger whip, to a yagi that breaks down into two dozen pieces, to a dipole held up at the center by a willing (and tall) campmate. The variety (and price range) of such antennas is staggering. I've had pretty amazing results using short, base-loaded antennas on the higher bands--especially when conditions were good. My personal best is JA from W6 on 15-meter SSB, running 3 watts to a Maldol 48" whip. These antennas collapse and break down into just two pieces, taking very little space in my lightweight go-bag. This leaves room for a couple of 25' wires, adapters, and weights for times when there are trees available. But the search for the ideal miniature HF antenna continues: something both very compact *and* highly efficient. Ideally it would break down to a length of 8" or less, do an excellent job on 20 meters and up, and earn a passing grade on 30 and/or 40 meters. One other key factor, at least with the KX3/KX1/K1 genre, is to take maximal advantage of the rig's internal ATU. A wide-range ATU (such as the KXAT3) can turn a narrow-banded antenna into one that covers a full band or even multiple bands, within limits. One general approach is to coarse-tune the antenna's own inductance, then let the ATU do cleanup. Is the best antenna for backpacking a very small magnetic loop? A cleverly designed, center-loaded telescoping whip? A length of #30 wire lofted by a small helium balloon? (Or, more intriguingly, some combination of these?) I'd be interested in hearing about your antenna theories and field experiences, backed up by entertaining fish stories, if they aren't embellished to an embarrassing degree. If your supporting documentation is too voluminous for the forum (attached photos, etc.), feel free to email me directly. If anything substantive or surprising emerges, I'll do a followup posting. 73, Wayne N6KR From dledoux at camtel.net Sun Jul 19 12:48:30 2015 From: dledoux at camtel.net (Dale LeDoux) Date: Sun, 19 Jul 2015 11:48:30 -0500 Subject: [Elecraft] Miniature self-supporting HF antennas In-Reply-To: <11BAB451-4FA8-45C3-975F-0210C17C5A9D@elecraft.com> References: <11BAB451-4FA8-45C3-975F-0210C17C5A9D@elecraft.com> Message-ID: <104C1A6E-984B-4B30-8BC2-7D5288F1F351@camtel.net> I?m interested in where this one?s going.

I usually lecture on antennas targeting the new ham. There are two points I try to leave the crowd with: 1. There is no such thing as the perfect antenna. Each is a compromise of some sort. 2. No ham has too many antennas. Efficiency, size, effectiveness, cost, and bandwidth are all inter-connected. I wish you great success in your quest. I'll be watching as I too would like to discover the perfect antenna. Having said this, have you tried a vertical dipole fed with open wire or ladder line? You gain by having a low angle antenna with low transmission line loss, and it requires only one support. 73, Barry K3NDM ----- Original Message ----- From: "Wayne Burdick" To: "elecraft" Cc: "KX3" Sent: Sunday, July 19, 2015 12:45:47 PM Subject: [Elecraft] Miniature self-supporting HF antennas Hi all, Have you found the "perfect" above-the-treeline backpacking antenna for use with your KX3 or other small rig?

To launch it, I use an E-Z Hang (slingshot / fishing reel). The scrub on SoCal mountains is usable to support an end-fed wire, facing downhill. I recommend a counterpoise facing uphill. The end-fed can be 50 to 200 feet long (145 feet seems best all-around match using the ATU). I use a throway fishing weight to be the E-Z Hang projectile, tugging the #24 wire along until it bashes into a plant or the ground. The weight is attached to the wire via a short piece of thin monofilament, so it can break away without stretching the wire. I attach the radiator and counterpoise directly to the KX3 via a BNC - Banana adapter. When done, I just spool up the #24, usually losing the fishing weight in the process. If it's a multiple hilltop day, I have half a dozen of these in my pack. Being a sloper, it has some forward gain but a fairly high angle because of proximity to the ground. SoCal mountain "ground" is a rather vague concept though and I've made a few dozen DX contacts running 2-3W, CW. I have WAS done this way, minus RI and VT. I've had some luck using a "tilt up" telescoping aluminum 33 foot vertical on 40 and 15m, but the dern thing is unwieldy and heavy to pack around, and at 5.5 feet long (collapsed) only fits on my large hunting pack. I'd sure like to see a portable multi-band vertical that's easier to lug around than this, maybe one that collapses to less than four feet and weighs less than three pounds. The 33 footer weighs almost ten pounds.... I've stopped punishing myself, and don't use it much any more. No fish stories today, sorry. 73, matt W6NIA On Sun, 19 Jul 2015 09:45:47 -0700, you wrote: >Hi all, > >Have you found the "perfect" above-the-treeline backpacking antenna for use with your KX3 or other small rig?

In searching through the list archives, I noted that some K3 owners had previously expressed an interest in an Ethernet option - and some owners have been disappointed that the new K3s and KIO3B board does not include Ethernet connectivity. A bit of background: for the past few months, N4CC and I have been operating a remote Internet station that's located near the FL/GA state line. Our setup includes a K3 and RemoteRig at the remote site and either a K3 or K3-mini at the control locations. Since the installation, we've experienced almost no operating trouble and any issues that have developed are managed remotely though direct and back-door network access points. Last week, I made some internal changes to the K3 and also added an external USB data interface device for RTTY. What's apparent is that cable management is getting way out of control. To gain inside access to the K3 almost requires a meditation exercise before going in. Consider that a PR6 is mounted to the back of the K3. The rear of the K3 is an absolute rat's nest of cabling. With the RemoteRig and PR6, It was bad enough before the inclusion of the external USB sound car/interface, but now it's bordering on ridiculous. Moreover, RemoteRig does not allow clean access to the K3's ACC DB-15 connector for other purposes such as FSK keying. Sure, the connector can be opened to access pins, but it requires a wiring break-out, leading to yet a further rat's nest of cabling. To help deal with the cabling issues, I am replacing the external PR6 with the new KXVB3 board. Next, a KIO3B board will be added when it's available to existing K3 owners. That should eliminate the external sound card interface and clear up much of the cabling mess, but not all of it. The Holy Grail is an Ethernet interface that includes (optional) integrated RemoteRig hardware - just one interface board [e.g., KIO3E(thernet) board] that manages K3 Ethernet connectivity with or without RemoteRig attributes. Don't need Ethernet? Then don't get the board. Since the RemoteRig hardware is mature and consumes little circuit board space and DC current, perhaps it would be worth opening up a discussion with RemoteRig's designer since Elecraft already has a close relationship with Microbit. I know rear panel real estate is a concern, so it won't be easy to add yet another connector without adversely affecting other connectivity. Thoughts?

Pretty much all host programs these days use a serial interface. We usually use this through a USB-Serial adapter or through built-in serial ports, which are rapidly disappearing. To make this viable we would need drivers for all major platforms that implement a serial port driver interface to ethernet. Or, the host programs will need to be modified. There is a lot of work needed to make this suggestion viable, both on the host and radio sides. This is the fact same reason we still use serial interfaces for our rigs instead of true USB interface. Put forth a good proposal and let it be considered. Without that work (whoever does it), ethernet hardware isn?t very useful. - Jack, W6FB p.s., no, this isn?t a flame, but a challenge.

Would it be feasible to disconnect it from the K3, tune it to 40 meters, transmit AFSK A RTTY at low power into a dummy load, and observe the transmitter's spectrum? Might need a short "antenna" in the BNC connector? In the NAQP RTTY, I observed a station on the other side of the continent with a 20-25 KHz "noise bump" above [but not below] his signal. It was 8-10 dB above the ambient noise baseline. I watched it for quite awhile and every time he transmitted, it appeared, and when he finished it disappeared. No other station, even very strong ones, exhibited this effect. It's hard to conjure up how any form of phase noise would be asymmetric like this. It could be some form if IMD in his TX RF chain, I guess. Another possibility is he was running AFSK USB and the noise was being generated in the sound card. This could easily be me as well and I'd like to check. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org From elecraft at mailman.qth.net Sun Jul 19 17:28:31 2015 From: elecraft at mailman.qth.net (Robert Tucker via Elecraft) Date: Sun, 19 Jul 2015 16:28:31 -0500 Subject: [Elecraft] K3 Below 500 KHz RX Antenna Message-ID: <2606B7BC-C6B0-4840-9B0F-754923069333@aol.com> >> phil, K7PEH, asked: >> What is the cheapest easiest although effective RX antenna for >> listening to whatever below 500 KHz with a K3...

Nevertheless, let's say native Ethernet control isn't worth the engineering effort. That should not preclude the integration of RemoteRig as an option into a K3/K3s. If I didn't care about the resale value of my K3 or RemoteRig, I could easily turn this into a weekend construction project and be up and running on Monday morning with an Ethernet cable hanging from the back of the K3. The RemoteRig board would come out of its enclosure then mount in the K3. It's just a matter of adding an RJ45 port, tapping +12V, internal audio, RS-232, PTT, key line, and ACC. The tapping of RS232 and audio is not trivial but it is completely manageable. While this adds little additional operational utility than it does now, it significantly cleans up K3 cabling with RemoteRig. No change is needed at the client end for use with the K3 mini. For K3 clients, a similar integration could accomplished or kept as it is now with external cabling. Of course, there must be enough demand from remote users to make it worthwhile as well as cooperation from Microbit.

Might need a short "antenna" in the BNC connector? Yes. The P3 will tune up to about 22 MHz (and above that with reduced sensitivity). If you go into the "Xcvr Sel" menu item and select the last item in the list, called "0 Hz". the P3 is tuned directly to the frequency on the screen. Tune using the CENTER control. (Center En has to be enabled in the menu.) The tuning rate is proportional to span, so select wide span for coarse tuning and then narrow span to dial in to the exact desired center frequency. One warning: The P3 IF input is unprotected so it is easily damaged by static discharge or high power. I recommend adding a pair of back-to-back switching diodes in parallel across the IF input. I did that using a BNC T connector and BNC plug so I wouldn't have to modify the P3.

Please publish the specs. How secure it it? SSL? TLS 1.2 (or better)? Will there be accommodations for upgrades as security problems are found? Does it do ipv6 (which is rapidly becoming a requirement)? My concern is this - we are putting a rather powerful transceiver on the internet. With Telnet or any other non-secure format/protocol there is a lot of potential for someone to take over the data stream and use the transceiver for their use. Even with secure protocols there has been a very poor record of vulnerabilities and other problems taking over computers, breaking in for information or other problems. Exposing a ham transceiver to this endangers your license and our spectrum. Anything that is not secure should not come close to a radio. Today that means TLS 1.2 and full security. And updates to fix bugs as they are exposed. We are at the beginning of the age of IOT, the Internet Of Things. There are many very good manufacturers working on chips and interfaces for embedded devices - refrigerators, lights, cars, and even ham transceivers. These will be secure and will accommodate the requirements I describe above and many more in a way that allows us to simply expand the radios we have now with new cards. This stuff is starting to come to market now - I would suggest we are a year to two off from adding them to our devices. Then we need to convince the ham software developers to start adding support for them in all the flavors that already exist. I suspect that won?t be very difficult when they find a willing market. Good luck with your venture. I?d love to see it when it becomes available. We need to see things like this to interest hams, show them (and us) what is possible, advance the state of the art and even to expose vulnerabilities with current schemes so we can all do (and demand) better. - Jack, W6FB p.s.

If i'm going to be portable for a while Ill put the 3 element antenna up. Its pretty fiddly and changing bands is a pain. Its one band at a time. The performance is very good and it really lightweight and small to pack.The TW antenna works great and takes 5 minutes to set up. In a nutshell it's a DX antenna. Distant stations are worked with amazing frequency for such a small antenna. Its my favorite portable. Its actually larger to pack than the 3 element without the mast. However, that fades when its quickly set up and working. Like any antenna, keep them away from noise sources and in the clear and the results will be good. George NE2I ?

In-Reply-To: References: Message-ID: <58E9AA74-6004-4227-A345-593CD9D8D284@i29.net> Hi to the group I know this is long so if you are not interested in Solar Field Days please hit delete. I am late telling about my experience with Field Day but I had so much research going that I wanted to wait until after my two week vacation to tell you all about it. I have been using class 1B ND battery all but one of the last 15 years. I started with my K2 built in 2000 along with a Radio Shack Tandy 1100FD laptop all running on an old group 27 battery. The year the battery was 18 years old it failed about 6 hours before the end of field day and would not take a charge again. I bought another group 27 battery and used my K3 and the 1100FD laptop the next year. The club talked me into running under my call the following year as a 100w 3A ND station using a Windows XP laptop and N3FJP software. The next year I had my new KX3 and went back to 1B ND battery. I used the I-PAD and Hamlog software but the I-PAD battery ran out of battery after just 7 hours of use. Last year I ran the KX3 and a Windows 8 laptop as 1B ND Battery but had to run the 40 watt laptop as the only load on my generator. I understand that meets the rules but I did not like it. This year I replaced all the lights in my camper with LED bulbs and dropped the load from 1.5 amps per bulb to 0.2 amp per bulb. I found a Verizon 12 volt power supply that would run an I-PAD and Hotspot at the same time on a discharging 12 volt battery. The I-PAD used about .4 amp as long as I was careful to turn the I-PAD OFF instead of to STANDBY when I was not using it. The I-PAD looks OFF when in STANDBY but runs the battery down doing things in the background and charges the battery when it is turned back on which draws additional 12 volt from the battery. I programed the fast memories of the KX3 for W0CZ, and 1B ND and used the built in paddles for anything else. You can see pictures of my camper and antenna on qrz.com. I also added a 33 ft MFJ fiber pole with a 29 ft vertical wire that loads on 40, 30, 20 and 15 meters using the KX3 built in tuner. A week before field day I was given ten five watt solar panels. Years ago I had built the KD5NDB solar regulator so I wired all 10 panels in parallel and the solar regulator to charge the battery. My results for field day were 132 cw five watt contacts with a claimed QSO score of 1320 plus bonus points for 100% emergency power, Natural power QSOs completed and using the b4h.net applet. The solar charger had my batteries fully charged by the end of field day after operating all night. Two days after field day we took off on a two week vacation to Northern Minnesota to camp grounds without electricity. I had the 8 year old group 27 battery and a 4 year old group 24 battery as my only source of electricity. I also had the KX3, PX3 and KXPA100 along and used the station extensively. The solar charger was able to recharge both batteries every day the sun was out and help them on the other days so I never did use the small generator I brought along. In bright sunlight I was able to make several nice rag chew CW QSOs at 100 watts. All my other contacts were at 50 watts night or day. I made one more change to my solar project when I got home. It is a Home Depot Grape Solar GS-STAR-100W panel. I found when I was camping that it was a lot of work to move 10 panels so this way when the sun moves I can follow it by just picking up the one panel. KD5NDB is a silent key and I do not know of anyone selling his kits but I did take pictures of his kit instructions and schematic drawing which I can E-Mail to anyone that wants to build this solar regulator. One advantage of his circuit is that it makes no RF noise. Many other SOLAR REGULATORS make serious RF noise. 73 and thanks for the band width Ken W0CZ w0cz at i29 dot net7 Sent from my iPad > On Jun 30, 2015, at 10:16 PM, Carol F.

My favorite antenna for SOTA turns out to be the 20 meter Endfedz followed by the Alex Loop. I have done a receive comparison between the Alex loop , Endfedz and a full size 20 meter vertical with radials. In this sketchy little test the Verical came out best followed very closely by the other two antennas. It was amazing to see how well the 3 foot diameter loop performed. I guess I would like a 20 meter 2 elment beam that sets up in 2 minutes and weighs two pounds. If it could pop open and shut like an umbrella that would work for me. Any ideas.

Think of the Hex Beam - 2 elements that sort of look like an inverted umbrella. 73, Don W3FPR On 7/19/2015 9:43 PM, Richard Donner wrote: > I guess I would like a 20 meter 2 elment beam that sets up in 2 minutes and > weighs two pounds.

JT-65 has common frequencies on each band. Then JT-9 is about 2 kHz higher from JT-65, thus the move in frequency. There is a box to be checked on the application when changing from JT-65 to JT-9. It is best if the radio is under CAT control.

However, it requires one rope into a tree or other type of sky-hook. It is good for 20, 17, 15, 12 and 10 and is bi-directional. It's a form of W8JK, but is fed at the end and has series capacitors in each radiator to make it work over a 2:1 frequency range. I designed it with EZNEC and I'll send the model to anybody who wants it. It's fed with window line and requires a balun at the transmitter. It takes a good tuner to match it, but the Elecraft tuners can do the job. Anyway, it doesn't meet Wayne's request for a free-standing antenna, but it's a cool field-day antenna, especially here in the middle of the country where a bi-directional antenna is a good thing.

The soil conductivity on most high mountaintops IS just plain awful. :) BUT -- there's nothing like having your antenna on a 3,000 ft tower, even if it is made of rock. When you get there, almost anything works, and anything decent works really well. W6GJB has a "go-kit" for his KX3 that includes a simple telescoping antenna that mounts to a tripod with a coax connector in the base, and a couple of wire radials that can be tossed into surrounding vegetation if there is any, or lay on the ground if there is not. Last summer as a site survey for FD, we set that up at Berryessa Peak (70 miles N of SF), and in about ten minutes, made three contest-style CW Qs to JA, SA, and the east coast of the US. Spiderbeam sells a 40ft (12M) telescoping fiberglass pole that weighs 7# and collapses to 3ft-10in. About $135 with shipping from TN). For about the same price, there's the DK9SQ 33 ft carbon fibre pole that collapses to 3.8 ft and weighs 2.2#. I used one of those with my K2 at my old Chicago club's annual QRP night in a local park. A photo is on my qrz.com page. I taped a #22 wire to it, wedged it between the seat and the top of the picnic bench (at roughly a 45 degree angle), and laid out two more wires as radials. Running 5W on 30M, I easily made a half dozen QSOs, including one that was a Caribbean station running a pileup. I agree that the Alex Loop, as well as home brew versions of it, can be a pretty decent backpacking antenna. W6GJB also has one of those. 73, Jim K9YC From pf at tippete.net Mon Jul 20 01:34:59 2015 From: pf at tippete.net (Pierfrancesco Caci) Date: Mon, 20 Jul 2015 07:34:59 +0200 Subject: [Elecraft] K3/K3s Ethernet Interface In-Reply-To: <1af201d0c26b$95f78420$c1e68c60$@wjschmidt.com> References: <000701d0c258$891ceff0$9b56cfd0$@arrl.net> <1af201d0c26b$95f78420$c1e68c60$@wjschmidt.com> Message-ID: <06E7C4FE-15C2-4B99-840C-433925641A66@tippete.net> On 19 July 2015 23:40:51 CEST, "Dr. William J.

Your software thinks it's talking to your radio via RS232... but really that is an emulation that gets ported over the Ethernet to the radio (where the Ethernet to RS232 server is) and deconstructed into RS232 (RXD and TXD) with DTR and RTS for keying. Your computer can be right next to your radio or half way around the world and the radio will never know the difference. Latency is not a problem. Second mode is WEB server where the radio is emulated in web pages in the onboard web server (eg web page looks like the radio). You can change any parameter in the setup or knob on the radio that you could via RS232. No security is provided. Nor is there with the FLEX, Ten-tec, or any other radio that has an Ethernet connection currently. I just use a Netgear firewall and VPN through it securely. Dr. William J.

You end up with a miniature signal which is not much use with QRP. I recently operated from Vanuatu as YJ0BJ and I used a Steppir CrankIR vertical for 10 - 40m. It worked very well indeed and whilst it does not assemble in two minutes, it does all pack away in the carry bag provided. However, you need a mounting post, fence post or something to mount it on. My holiday location was almost on the beach so arguably I had the salt water benefit. However, I have tried it here at home, now with the 80m extender kit (still all packs in the one bag) and it works OK. I will be on again from YJ0BJ in November 10 - 80m. The rig will again be my K3.

Simply use your current lowbands antenna 160/80m with good preselector (BPF+preamp) and you are "on board". I am using this setup for 137kHz and it works well for RX.

I have one with link breaks in it so that it can quickly be changed for different bands (using 2mm or 3mm radio-control power connectors for the breaks because they're very small, light, and make a good connection), and a couple of fibreglass telescopic flag-poles. One collapses to about 18 inches so fits in a back-pack easily enough, and extends to 18 feet. The other (which only goes on shorter walks) is about 28 foot long when extended, and about 3 foot 6 inches when collapsed. That set-up, however, doesn't fit Wayne's "breaks down to 8 inches" ideal.

I went with them because I have found USB cables seem to be pipelines for computer hash to get into my rigs. I just got tired of experimenting with ferrites every time I changed computers or connection schemes. I build my own cables out of cat 5 or higher UTP cable. StarTech makes great one- and two-port high speed PCI and PCIe rs-232/422 boards that work well with desktop computers. No issues with N1MM, winkeyer serial and NAP3. I also use WIFI exclusively in the shack (when operating) as I discovered my cable modem, located downstairs in the mud room "DMARC", propagates an unacceptable amount of hash into any rig when I connect shack computers to it via ethernet cabling. WIFI is a great way to reduce cable count too. $0.02 PS: all ideas above courtesy of K9YA's excellent RFI Cookbook. -- de AB1VL NAQCC #6799 ab1vl.com From rmcgraw at blomand.net Mon Jul 20 08:34:49 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Mon, 20 Jul 2015 07:34:49 -0500 Subject: [Elecraft] Driver Requirement for K3S Message-ID: <55ACEAE9.1080603@blomand.net> While waiting the arrival of my K3S, the question arises for the requirement for a Windows driver for USB connecton.

However, I now find the KX3 routinely overheats in digital modes. Specifically, at just 5 watts on WSPR with transmission time of 2 minutes (as regulated by WSPR software) the KX3 overheats "HI TEMP" at a minute and a half, resulting in a safety shutdown of the rig. This radio has a wonderful built-in digital capability, but digital appears beyond the rig's ability, save CW which is my main digital interest anyway. I would like to use the KX3 occasionally on PSK, JT65 and WSPR without the absurdity of having to buy an after-market heat sink to replace a factory installed heat sink. There is no guarantee the after-market one is superior, and it shouldn't be necessary since a radio with a digital capability should not need some after-market accessory to enable the advertised digital mode. I wonder if anyone has found a firmware or software answer to the over heating problem. The overheating problem happens regularly in digital modes and I believe comments about the KX3 working correctly in digital are simply incorrect. This is not an antenna issue and not an SWR issue.

As the new interface board in the K3s has its own USB Codec as I seem to recall, there should be no problems with HRD and FLDigi. I wonder if the new interface supports "true" FSK? That would require the K3s USB interface "linking" to the ACC connector.

Recognizing that more and more operators are using digital modes with extended key-down times, we recently replaced the supplied heat sink of the KX3 with one having significantly more thermal mass and radiation surface area. If your KX3 is an earlier one, and your operating preferences require longer key-down times at higher power levels than your thermal environment can reasonably handle, the improved heat sink is available at a nominal cost. An alternative is to run a bit less than 5 watts and find the balance of transmit time, local environment and mode preferences that work for you. Being a weak-signal mode, WSPR at 3 or even 4 watts is likely to work well for you with the radio as-is.

As part of the design process, I've compared it to an inverted Vee at the height where we could rig it without trees. The model, of course, is for "flatland," and while HFTA can tell us how being on that mountain affected the horizontally polarized inverted Vee, we have no comparable modeling for a vertically polarized antenna. So I asked Dean Straw, N6BV, retired ARRL Antenna Book editor and author of HFTA how he thought being on the mountain might affect the vertical. His answer was "I don't have a guess." Our vertical will be built from that modular army-surplus mast that comes in 4 ft sections that fit together with a 40 ft telescoping tube mounted to the top, with a wire taped to it. We will feed it as a vertical dipole, and there will be loading both at the bottom and top. Not at all suitable for backpacking. :) 73, Jim K9YC On Mon,7/20/2015 9:58 AM, Al Lorona wrote: > [I've re-named this thread.

I suggested they could make QSOs as fast or faster than PSK, RTTY, or voice. You can see some pics on QRZ searching NA3DX. It proved true. Our setup used a KX3 at 5w, Win4K3 Suite providing Panadapter and radio control interfacing, com0com com port control, CWSkimmer, and N1MM+. For them, CW was just another digital mode like PSK or RTTY. My neighbor 12 year old ended up operating on a main HF station operating this way and had a blast. He was getting as fast of some of the OMs doing S&P, too. My XYL says it is cheating, But my come back now is what do you do if your deaf or lose quality hearing. This setup works. You don't have to give up on weak signal cw contacts, contesting, or chatty qsos if you lose your hearing. BTW, I have confirmed contacts from DXing and contesting on CW with stations I could not hear any audio or see signal in the Panadapter. CW skimmer picked up the signal and decoded it. I wonder if you have seen this? K3NDM said he did but did believe it. When I worked them and got them confirmed in LoTW, he became a believer. So, just because you can't hear it or see it, cwskimmer can help you find it. I also think this is a good way to get ops going at CW. If they like it, they may naturally evolve into other variations of cw operating over time, with a key and decoding by ear. Thank you Elecraft for such a great radio. -- Doug Ellmore NA1DX "A Know Code Extra" doug at ellmore.net From gerry at w1ve.com Mon Jul 20 13:18:09 2015 From: gerry at w1ve.com (Gerry Hull) Date: Mon, 20 Jul 2015 13:18:09 -0400 Subject: [Elecraft] K3/K3s Ethernet Interface In-Reply-To: References: <000701d0c258$891ceff0$9b56cfd0$@arrl.net> <1af201d0c26b$95f78420$c1e68c60$@wjschmidt.com> <06E7C4FE-15C2-4B99-840C-433925641A66@tippete.net> <1b5c01d0c2b0$590e5ad0$0b2b1070$@wjschmidt.com> <2C11DAEC-C037-4AD9-93BC-4F7DB5011FBE@tippete.net> Message-ID: FB Bill, Yes, I have a couple of the boards.

As part of the design process, I've compared it to an inverted Vee at the height where we could rig it without trees. The model, of course, is for "flatland," and while HFTA can tell us how being on that mountain affected the horizontally polarized inverted Vee, we have no comparable modeling for a vertically polarized antenna. So I asked Dean Straw, N6BV, retired ARRL Antenna Book editor and author of HFTA how he thought being on the mountain might affect the vertical. His answer was "I don't have a guess." Our vertical will be built from that modular army-surplus mast that comes in 4 ft sections that fit together with a 40 ft telescoping tube mounted to the top, with a wire taped to it. We will feed it as a vertical dipole, and there will be loading both at the bottom and top. Not at all suitable for backpacking. :) 73, Jim K9YC On Mon,7/20/2015 9:58 AM, Al Lorona wrote: > [I've re-named this thread.

From what I understand PWM also cause radio interference. I believe that the older "diversion" controllers are quiet. Normally they would waste a lot of energy but if one were running enough equipment so the battery was being drained faster than it was being charged I assume there would not be much energy waste. My question is those of you who operate with a fairly good size panel and need a solar controller what do you use that produces no radio interference. I am looking at what would be set up for a RV or a good sized boat or a day or two portable operation for something like the US Island QSO party coming up. We would want to run 100 watts with the K3. This would be a 12 vdc system with something in the range of 100-140 watt panel. Probably two 6 vdc deep cycle batteries.

Unless you have a goodly stock of resistors and capacitors, that is likely to be the less expensive that ordering the parts one at a time. The only caution I can give is that some parts have changed recently, so download the latest manual and errata and build the RF Board from that - do not ignore the errata, mark up the manual with the changes. 73, Don W3FPR On 7/20/2015 4:08 PM, Louis C LaCour Jr wrote: > Hello All: > > I started to build a K2 a ways back, and since then have lost some of the packs of components (e.g. The resistors listed on p.48, Assembly Part II. > > I have completed the build up through and including Part I, but now I don't know that I can finish it.

This is the consequence of the fact that a loaded antenna has a very low radiation resistance, which magnifies the impact of all other system losses. ON4UN's excellent book Low-band DXing has a detailed analysis that can help you make the best choice of setup.

But > some of the best antennas on the market right now use coil loading > very effectively. There was an excellent piece in QEX a year or two ago devoted to the design of short loaded antennas. It was published in two parts -- one dealt with measurement, the other with studying the effect of the position of the loading coil. The executive summary -- the part of the antenna carrying the greatest current does the most radiating, and for most short antennas, that's the part of the antenna closest to the feedpoint. The current distribution depends on the electrical length, including that coil. A loading coil near the feedpoint seriously degrades the radiation efficiency of the antenna, because the current maxima is in the coil, but the coil doesn't radiate! SO -- loading should be as far as possible from the feedpoint! All of this was borne out by the measurments. 73, Jim K9YC From roncerra at earthlink.net Mon Jul 20 17:50:10 2015 From: roncerra at earthlink.net (KM4VX) Date: Mon, 20 Jul 2015 14:50:10 -0700 (MST) Subject: [Elecraft] KX3 and Digital Modea In-Reply-To: <1437425585791-7605148.post@n2.nabble.com> References: <1437398899812-7605122.post@n2.nabble.com> <1437425585791-7605148.post@n2.nabble.com> Message-ID: <1437429010658-7605158.post@n2.nabble.com> Lyle: Thank you.

What it will do is reduce the frequency drift over a wide frequency range - so for maintaining frequency stability while the KX3 is heating up, yes that stability will be increased. The temperature problem with extended transmit 'key down' times is what is causing the heating. Cooling the PA transistors or reducing the power is is the only way to reduce the effects of high temperature. The new heatsink will help, lowering the power will help, a fan blowing on the heatsink will help, an aftermarket heatsink will help. Anything to keep the PA transistors cooler. 73, Don W3FPR On 7/20/2015 6:39 PM, Milverton M.

Use only 1N5711s if you want the best voltage response vs. frequency. Those parameters are not specified. Elecraft chose those diodes long ago based on testing for that frequency response. If you are looking for alternatives, and do not care about the readings obtained at lower power levels (QRP), then you could use 1N4148 diodes which are plentiful. 73, Don W3FPR On 7/20/2015 7:31 PM, JeremyJones wrote: > What are the specs for the diodes?

If not, please re-do the measurements. Assuming that you were set for ATU CAL, I can offer these comments: With the configuration you have now - KAT2 and KPA100 out of the picture, those results indicate that 1) the KAT100 wattmeter is not properly balanced and calibrated, or 2) something in the KAT100 wattmeter has been damaged - most likely diodes D1 and D2. It is possible that the diodes have been 'partially damaged' and have become frequency sensitive. With a dummy load connected and the ATU menu set to CAL, you should have a 1.0 SWR on all bands. The fact that you do not says that either the wattmeter is not properly balanced, or one or both diodes are bad, or that there is some random L/C element stuck in the path to he dummy load (that would be a relay problem). I would arbitrarily replace D1 and D2, and then attempt to balance and calibrate the KAT100 wattmeter as indicated in the KAT100 manual. If you cannot achieve a good null when balancing, just stop - attempting further steps is futile until you can obtain a good null. 73, Don W3FPR On 7/20/2015 7:15 PM, JeremyJones wrote: > Ok, so I've removed the KPA100 completely, and disconnected the KAT2 serial > and RF connections.

No radio (except an Alpha amp is designed to do that). As Lyle states it is a thermal issue and not a digital design issue. Either run less power to keep from overheating or consider installing a bigger heat sink. I opted for the bigger heat sink from VE7FMN (link on my KX3 webpage. It was easy to install (a couple bolts using a allen wrench which he can supply). I have tested running 5w on 6m for extended time and difficult to reach overtemp with the new heat sink. http://www.kl7uw.com/KX3.htm Testing duplicated running JT65 which is key-down about 50-seconds followed by 70-seconds in receive. If you are running psk31 you may have to limit the time you send text in one period. WSPR is the most demanding with 2-min key-down Tx periods. I have not run the KX3 in WSPR as I usually use my K3/10 which may have different heat sink characteristics. 73, Ed - KL7UW --------------------- From: KM4VX To: elecraft at mailman.qth.net Subject: [Elecraft] KX3 and Digital Modea Message-ID: <1437398899812-7605122.post at n2.nabble.com> Content-Type: text/plain; charset=us-ascii I am on my second KX3, having sold the first one and then find myself missing it. However, I now find the KX3 routinely overheats in digital modes. Specifically, at just 5 watts on WSPR with transmission time of 2 minutes (as regulated by WSPR software) the KX3 overheats "HI TEMP" at a minute and a half, resulting in a safety shutdown of the rig. This radio has a wonderful built-in digital capability, but digital appears beyond the rig's ability, save CW which is my main digital interest anyway. I would like to use the KX3 occasionally on PSK, JT65 and WSPR without the absurdity of having to buy an after-market heat sink to replace a factory installed heat sink. There is no guarantee the after-market one is superior, and it shouldn't be necessary since a radio with a digital capability should not need some after-market accessory to enable the advertised digital mode. I wonder if anyone has found a firmware or software answer to the over heating problem. The overheating problem happens regularly in digital modes and I believe comments about the KX3 working correctly in digital are simply incorrect. This is not an antenna issue and not an SWR issue.

It was highly overpriced at over $11 each. The Aligent data sheet for the 1N5711 shows it to be a 15 ma device. You would do better to order from Elecraft. Order E560004 - Diode, 1N5711, small glass body from parts at elecraft.com. Order 2 of them (or possibly 4 since you do not yet know the status of those in the KPA100). An alternate source is "The Toroid King" http://www.partsandkits.com. Diz prices his 1N5711 diodes at 10 for $2 (plus shipping). I have purchased those diodes from Diz for a long time - never a problem. Yes, those test results are not valid unless the KAT100 was in CAL - in any other setting there would have been L and C elements active, and the goal is to test the wattmeter as the first step. 73, Don W3FPR On 7/20/2015 7:59 PM, JeremyJones wrote: > The diodes I was looking at were 1N5711, but they were either 70V 15mA > (http://www.digikey.ca/scripts/DkSearch/dksus.dll?Detail&itemSeq=176360177&uq=635730153536694158) > or 70V 33mA > (http://www.digikey.ca/product-search/en/discrete-semiconductor-products/diodes-rectifiers-single/1376383?k=1n5711). > > I just want to make sure I get one with the proper rating. > > I did not have the KAT100 in CAL mode.

A magnetic loop is relatively heavy for portable QRP. Verticals made of piece of wire are great over salt water or when conditions are great. For support I use 25ft pole collapsible to 2 ft. Away from the sea, two long wires made of thin wire are best IMHO. Or one long wire with a shorter wire. I understand that hanging a long wire is harder than shooting a vertical. When in VK I had 2 70 ft long wires just 20ft high, plus a 30ft vertical plus a couple of radials. This was far from water on a flat land. I could make an antenna from any combination of long wires, a radial or a vertical. Nearly always the best antenna was 2 long wires connected directly to a tuner, and very rarely one long wire with a vertical. In no case was the vertical with radials best. The reason a long wire is better than a vertical (most of the time) is lower losses and more radiation at many angles. So a greater chance of success somewhere.

I installed the VE7FMN heatsink after experiencing overheating issues running SSB on 10m in California summer weather. I subsequently got into JT65/JT9, and after doing the temperature calibration, the addition of the heatsink is allowing me to run at 10W on 20m and below. Not sure whether this performance can be maintained on the higher frequency bands but at least I'm up and running. I like the KX3 a lot - I've nearly 2000 portable SOTA contacts and I'm rapidly adding digital contacts from the home QTH but it's not perfect. It's a radio that needs a little extra work. IMHO for portable SOTA operation the SideKX by GEM Products is a must and a third party heatsink is a must for digital. I'd love the radio if Elecraft had done this from the outset but they did not and fortunately some good third party suppliers have neatly solved a couple of significant shortcomings. 73's Gary K6YOA Message: 3 Date: Mon, 20 Jul 2015 06:28:19 -0700 (MST) From: KM4VX To:elecraft at mailman.qth.net Subject: [Elecraft] KX3 and Digital Modea Message-ID:<1437398899812-7605122.post at n2.nabble.com> Content-Type: text/plain; charset=us-ascii I am on my second KX3, having sold the first one and then find myself missing it.

I have used Magnetic Loops for at least the past 10 years (I have an MFJ and an Alex Loop and I have built a few homebrew ones for portable use) and I can say that the only real compromise when using a well built 1 meter diameter loop on 20m through 10m is bandwidth. Efficiency on the higher bands is good to excellent (usually ranging from about 30% up to about 90% on 10m). The efficiency does suffer when pushing a loop this small to cover 30m and 40m but it isn?t so bad as to make it impossible to make QSOs at the 5w to 10w level, even on SSB. The problem with 1/4 wave verticals (including loaded ones) is that they rely on radials / earth to complete the other half of the antenna and unless you want to spend a lot of time deploying radials (which I think defeats the whole purpose of this thread) then results are going to vary a lot depending on the soil conductivity. I think that most Hams would be quite surprised at how inefficient a short vertical with few radials really is, especially over rocky terrain. Using them near salt water is whole different story. Horizontal antennas require supports, so they are by definition not self-supporting. On most of the HF bands reasonable height is required to achieve any kind of half decent take-off angles for DX. Over poor soil you don?t have the efficiency issues you do with verticals. Moxon in his excellent book "HF Antennas for all Locations?, suggests that if you are on a mountain/hill you can use the terrain to your advantage by mounting a low inverted-vee doublet, partway down the hill in the direction you want to work. This will significantly lower the take-off angle and can be quite effective for working DX in this sort of environment ? but it still requires a support and this only works on a hill. So what does a well constructed 1 meter diameter Magnetic Loop give you : PROs - continuous coverage from 40m through 10m with a very close match to 50 ohms (SWR under 1.5:1 usually at resonance) on all bands - good efficiency from 20m through 10m and reduced, but usable, efficiency on 30m and 40m (assuming proper design and construction of the loop) - both high angle (useful for close-in NVIS contacts on 40m) and low angle radiation for DX on higher bands (note that the radiation pattern is a donut standing on its end) - no need for an antenna tuner (in fact it is not recommended; all tuning should be done by adjusting the capacitor on the loop) - at heights in excess of 1 radius (i.e. 1.5 feet from the bottom of the loop) very good ground independence, which makes tuning predictable regardless of terrain. - self contained, self supporting (with small tripod), compact and lightweight making it quite portable - directionality. A magnetic loop has bidirectional radiation pattern with lobes in the plane of the loop and a fairly deep null broadside - very quiet antenna on receive and from my experiences even a slight rotation of the loop can drastically reduce nearby electrical interference - 5 minute (or less) setup and takedown time - fairly low wind resistance (you will realize the importance of this if you have ever operated on the top of a mountain ! ) CONs - mediocre performance on 40m / 30m (for a 1 meter diameter loop) - narrow bandwidth (typically around 10 Khz 2:1 SWR bandwidth when tuned to resonance on a given band) This varies from band to band but you can expect a wider bandwidth on the higher bands and narrower bandwidth on the lower bands. This means that sitting on a frequency and calling CQ works great, while S&P is a little more work as it requires frequent tweaking of the loop capacitor to resonate the antenna as there frequency changes - requires a means of either measuring SWR or Field Strength to adjust the tuning capacitor to resonate the loop for lowest SWR. - need to consider RF exposure and limit power to 5W to 10W for a manually tuned loop. Also the operator should not be closer than about 1 meter from the loop during TX at these power levels (I personally try to always sit broadside to the loop, no closer than arms length) - possible RF burn hazard. This is especially true for a home-brew loop with a bare radiator (i.e. copper or aluminum) and not as much of an issue for an antenna like the Alex Loop as the coax jacket provides protection. Observations - manual tuning works well with a little practice and often it is possible to achieve a 1:1 SWR just tuning by ear and peaking band noise. - for S&P, moving off frequency a few KHz from the desired station and quick re-tweaking is pretty quick, but doesn?t work with a heavily occupied band (think Field Day on 20m) unless you want to be rude and TX over someone else (not recommended). - I can?t stress the importance of proper design and construction of a loop if you are home-brewing. Everything should be soldered/braised/welded and you must use a split-stator or butterfly capacitor otherwise efficiency will suffer greatly. - wide 2:1 SWR bandwidth on a home-brew loop is an indication of very poor efficiency. The trade-off with a Magnetic loop is between efficiency and bandwidth ? you can?t have both at the same time. One area for improvement, in my opinion, would be to apply some smarts to (semi)-automatic tuning of the loop. With the technology available to us today it should be possible to (semi)-automatically tune a magnetic loop to resonance as the user changes bands and frequencies. I could foresee something like a mini VNA housed inside the same box as the capacitor, being fed band/frequency data from the rig via Bluetooth (hey, I might as well think big ! ). Loop tuning should be possible without transmitting a signal from the rig itself. Also because of the previously mentioned ground independence, it should be possible to go through a calibration process to allow the loop tuning circuitry to figure out what capacitor position corresponds to a given band and save that information as a preset for future use. This would make band to band QSYs happen a lot more quickly as it would have a good guess at a starting point for tuning each band. I think that smart tuning technology would go a long way towards addressing what I see as the one major issue with a portable Magnetic loop which is the narrow bandwidth and the need for frequent retuning. Michael VE3WMB / VA2NB P.S. The standard disclaimer, I have no personal or financial interest in Alex Loop.

I have a desk mic, Kenwood MC60 and use via extension cables either a Yamaha CM500 or Heil to the rear Jacks when I want to use a headset boom mic. it is a FP to rear panel switch. However, I have always thought that all the parameters for that change should be stored so the change is seamless. Gain, bias, EQ, compression etc, Be pretty much set and forget. I'll confess to not knowing all involved in doing it but to the Elecraft staff that knows, this is a HINT that may possibly be added to the list. 73, Bob K2TK ex KN2TKR (1956) & K2TKR On 7/21/2015 1:03 PM, Don Wilhelm wrote: > Todd, > > You would have to write a couple macros. > > 73, > Don W3FPR > > On 7/21/2015 12:56 PM, todd ruby wrote: >> I have 2 very different microphones each of which would need its own TX EQ >> settings that would be very different.

Certainly, examples can be found of inefficient antennas which suffer some inefficiency because of the coils but generally, the inefficiency is due to the need for the coils in the first place. Any antenna satisfying what I perceive are Wayne's needs is going to be inefficient because it is small and operated in close proximity to Mother Earth. There is a good chance that conductor and ground losses swamp coil loss. If one is going to compare one antenna with loading coils to another without coils to determine efficiency then they they must be tested under the exact conditions. In other words, take measurements of antenna one, remove it and replace it with antenna two and note the change. Any other comparison is uncontrolled and suspect.

Message-ID: <55AEB5AA.5040401@verinet.com> Hi all. I have K2 #3745 that was purchased in kit form on 12 Sept 2003. It includes K160RX, KNB2 and KSB2. It was built by someone on the Elecraft builders list. It was built some months after the kit was bought so the builder also installed the key click mod that came out after I bought the kit. I planned to use the K2 with transverters but never got around to it. It has maybe 20 hours of use and is in excellent condition. I need to get an idea of a fair price. Guess I could just put it on EBay but prefer a personal sale if possible. thanks, Jay K0GU From jbc5 at case.edu Tue Jul 21 17:42:30 2015 From: jbc5 at case.edu (Joe Carter) Date: Tue, 21 Jul 2015 17:42:30 -0400 Subject: [Elecraft] OT, FS PR6-10, KXPS3, Signallink In-Reply-To: References: Message-ID: PR6-10 and Signalink sold - thanks to all.

I already had the KXV3A installed and consequently didn't need to access jumpers W1 and W2 on the RF board. I decided to see if, by removing the side panel I would have sufficient access and visibility to swap out the module without having to first remove the K144XV and the sub-RX. It can be done, with care. Whatever, I would suggest removing the side panel no matter which route you take. Hate those TMP connectors. Looking forward to S-meter ABS mode being coded to compensate for the extra gain of PRE 2. One more thing. I did the recommended TX gain calibration which went OK using the K3 Utility. Thought that given the RX signal path had been modified I would do the RX gain calibration. Again used the K3 Utility with XG3 on 20m so PRE 2 shouldn't be a feature. Failed completely with a couple of different error codes the detail of which I cannot remember except for one which suggested I reload the DSP firmware. More scary was that the RX seemed suddenly deaf only to discover the RX ant function had been activated.

Is this correct? If so, you are not determining the effects of loading coil loss, you are determining that a vertical antenna is different from a (nominally) horizontal antenna. It takes no experimentation to know this.

The object of my exercise was not to measure the exact losses in the loading coil, nor to determine why it made such a poor antenna, but to determine which antenna would work best for the appropriate bands from a SOTA summit. The antennas under consideration were the loaded vertical (adjustable for all the bands required), a link-dipole (covering bands up to 15 metres), and various mono-band elevated ground plane verticals (one for each band from 20 metres to 10, though only 12 and 10 aren't covered by the dipole). I'd taken the loaded vertical on a couple of activations. One had been a reasonable activation (14 contacts on bands between 40 metres and 12 metres) and one had been a struggle (just 4 contacts, enough for the points, in over an hour and a half of calling on HF between 60 metres and 12 metres, with me resorting to CW for the last contact), but on both I'd noticed the reports I was being given were lower than I'd have expected. My friend could only help with the lower HF bands, so I have more confidence in those tests, and I wasn't expecting the loaded vertical to shine when compared to the dipole, but the magnitude of the difference was surprisingly wide. To give myself a baseline expectation I'd first tried contacting him with my (then) main 27ft tall vertical (which had some top-loading and a feed-point ATU), both with my main rig and the KX3 I planned to use to test the portable antennas. Somewhere I had detailed notes of all the numbers, but I can't find them. However, the QSOs are also in my log, and with the main rig at 100 watts we reported 5 and 9 both ways. With the KX3 at 10 watts we reported 5 and 7 both ways. I then took the KX3 outside to test the portable antennas, using it at the same 10 watt level. The best QSO on the loaded vertical has me giving him 5 and 1, and he giving me 3 and 1. On the dipole the log says 5 and 9 both ways. Some of that will be down to radiation pattern, height above ground, and so on, but it confirmed experience from the second summit mentioned above. Clearly, if I want to make contacts on the lower HF bands then the dipole is a far better bet. For the higher bands I had to rely on RBN and any contacts who happened to answer, so the comparison's a bit harder to quantify exactly. (RBN skimmers don't report every CQ, so you have to play games changing frequencies, and waiting, in order to get enough coverage.) However, as best I could figure, the loaded vertical was well down on the un-loaded mono-band ones as well as on the link dipole. Again, height above ground level will have had some effect. The loaded vertical has its own little tripod, so isn't far off the ground. The others all rely on telescopic fishing poles, so they're at least a few feet higher off the ground. In all cases the loaded vertical was worst, in some cases by a very large margin. At best (on 10 metres, which was clearly its best band) it was only 6dB or so so down on the elevated ground-plane vertical. That could be down to elevation, radials, the loading coil, or all three. I'd rather over-optimistically hoped that the self-supporting loaded vertical (total weight 1.5kgs) would do the SOTA job nicely. The dipole, a couple of verticals for the bands the dipole doesn't cover, pegs, guys, and a short (6 metre) telescopic pole weigh 2kgs in total. For SOTA purposes the loaded vertical was not worth carrying despite its (mostly) glowing reviews on eHam. Sure, I've made a few contacts with it from SOTA summits, so it wasn't totally useless, but the alternatives I now take are far better. Next time I'm tempted to make a link-dipole I'll make sure it has additional links for 10 and 12 metres so I can save myself the weight of the elevated ground-plane verticals I usually carry for those bands.

Yesterday I have been reading about the options of the K3 and the P3 and I seriously considered to sell all my Kx3 stuff to get a K3 Combo. But when I did my math, there was a huge gab concerning money. But I remembered some emails from Wayne, where he wrote more than a year ago, that they designed the Px3 to be compatible to their developments of the P3. So are there any developments concerning the SVGA HDMI- Mini Module for the Px3? Just for the record: I am also interested in the USB-Keyboard connection and what I found out yesterday: The P3 can send commands with the function keys to the K3 and I thought that this would be also an option for the Px3. So you Elecraft Guys over there: Think also about the hams, who can not afford a full blown K3 and have to deal with the Kx3 as their main rig at home. 73 de Hajo (DL1SDZ) --- Cela est bien dit, ...,mais il fault cultiver notre jardin.

For most of the roads in the US, you'll want a semi-rigid mount but soft enough that a hard bounce won't jar anything loose. If your travel include off pavement, it will be the same, only beefier. Padding between the station elements should also be considered. The second side of that is if you pad and strap, what do you have to do to make it operable with adequate cooling? Ideally, it should be able to travel in a ready to use configuration (no covers to remove etc). The final issue is to make the appearance pleasing to your YL to keep the ambient noise level low. ;o) With that in mind, a dedicated cabinet (close the door when not in use, or under the dinette etc), with semi-rigid foam (from a craft shop) under/between the rig(s) then soft adjustable straps over the top (left-right/front-back) to keep pieces from launching on a bounce would seem the best overall. (A small net would seem ideal.) A small computer grade fan keeps the air moving without excessive drain on the energy budget. Heat bad. Remember that the entire K line can be controlled via a computer (laptop, built-in tiny 'puter) so actual physical access is not required after power on so mounting locations is only limited by your imagination. With a small computer at the radio site (for remote control) near the living room TV in could also be part of a media center as well as allowing wifi control of the rig(s). Neither requires a lot of computing power, so a mini-atx in a small box is plenty and takes little room (12 watts of energy for the budget). You're only limited by space, your traveling companion(s) and imagination. Try to think out of the box, fun things can happen. 73, Rick wa6nhc From w3fpr at embarqmail.com Wed Jul 22 11:06:00 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Wed, 22 Jul 2015 11:06:00 -0400 Subject: [Elecraft] K-Line mounting In-Reply-To: <55AFAA0F.4010201@gmail.com> References: <55AFA3A9.5080108@gmail.com> <55AFAA0F.4010201@gmail.com> Message-ID: <55AFB158.90804@embarqmail.com> If it were my K-Line in a motorhome - and assuming it would not be operated during travel, I would build a custom box cover (or more to the point, a shell) for it - likely out of plywood. My vision is that box cover would have partitions that would fit between each of the K-Line boxes, and would have a layer of cloth or felt glued to the surfaces that contact the K-Line gear. Those partitions would require that each piece of the K-Line be spaced apart slightly, but assures that they do not rub against each other during travel. For the front and back sides, I would not use a full cover, but just have the wood extend only far enough to secure the equipment from moving front to back - the wood grasps the top edge of the equipment, but not the full surface. That allows the cables to be left in place and the knobs exposed. For travel, I would lower the tilt bails on each piece of equipment, put the cover box in place and strap that box to the table with a web strap. That way nothing moves during travel. When parked at the site, remove the web strap and stow the cover.

And I also had a couple of QSOs on 40m with French hams who could hear me fairly well in a large part of the country - not everywhere though, 5W on a 1m diameter magloop on 7MHz only takes you so far. I am in Dallas TX right now, and I spent time on 20m phone last night: 59 reports from Georgia and Montreal, CA, with a long QSO with two very friendly hams from Canada. We even had two guys from Reunion Island join us - one of them could not hear me, the other said he could, then band conditions changed and everyone drowned into band noise before I could complete the QSO... that's the life of a QRP operator. When I know I can operate outside, a Sotabeams fiberglass pole with thin wire and a 9:1 Unun (http://www.aerodynes.fr/2014/05/18/peanut-balun/) do a nice job, but they are impractical in cities, of course. Only circumstantial evidence, I know, and anyone can do a QRP phone QSO around the globe if conditions are just right, but still, I have tried quite a few 'hotel room' setups, and right now, Alexloop/KX3 is really my favorite. Now, if only more North American hotels allowed their guests to open their windows... My two last points: 1) I'm tempted to build an autotuner for the AlexLoop, I have a couple of ideas on how to do this very simply, stay tuned (pun intended). 2) Even on a Magloop, the PX3 is useful, and I would like to make the PX3 battery operated as well. There is definitely room in the box, and looking at the PCB, there is a connector inside just for that purpose, right Wayne ? 73 de Ed W6ELA On Sun, Jul 19, 2015 at 11:45 AM, Wayne Burdick n6kr at elecraft.com [KX3] < KX3 at yahoogroups.com> wrote: > > > Hi all, > > Have you found the "perfect" above-the-treeline backpacking antenna for > use with your KX3 or other small rig?

Message-ID: <55AEB1E8.7000203@verinet.com> Hi all. I have K2 #3745 that was purchased in kit form on 12 Sept 2003. It includes K160RX, KNB2 and KSB2. It was built by someone on the Elecraft builders list. It was built some months after the kit was bought so the builder also installed the key click mod that came out after I bought the kit. I planned to use the K2 with transverters but never got around to it. It has maybe 20 hours of use and is in excellent condition. I need to get an idea of a fair price. Guess I could just put it on EBay but prefer a personal sale if possible. thanks, Jay K0GU From doug at ellmore.net Wed Jul 22 13:36:14 2015 From: doug at ellmore.net (Doug Ellmore) Date: Wed, 22 Jul 2015 13:36:14 -0400 Subject: [Elecraft] CW Skimmer Setup with K3 and KX3 Message-ID: Gerard, CW skimmer works great with the KX3 and K3. If you look on my QRZ page (call sign NA1DX), there is a picture from my RV in Delaware this past weekend. I was QRV with my KX3 feeding a R5 off the side of our RV. I made a number of QSOs SSB, CW, including a bunch during the NAQP RTTY contest. I used CW Skimmer with the KX3 using the internal DELL XPS12 laptop sound card. I pointed CWSkimmer to the soundcard. (I/Q out to Mic in of the sound card). Using CWSkimmer, I have Win4K3 suite and N1MM+ connected to the CWSkimmer Telnet port and grabbing spots. To get to the next tier of high quality decoding, use an external 196k sub sound card. There are a couple good ones: - Asus Xonar U7 USB, simple stereo interface into the sound card from the KX3 - Steinberg UR22, requires stereo to two mono cable splitter - CreateLab E-MU, either direct stereo or two mono channels We had great success with the Asus Xonar U7 during field day. BTW, be prepared to decode cw signals you don't hear over the air or see on spectrum. During contests when I CQ, I have had a stations reply and I never heard them, but I worked them from the decode of cwskimmer. Attached is quick overview of the configuration which includes Win4K3 suite. I plan to update it sometime soon.

In-Reply-To: References: Message-ID: <55AFEBD4.5010306@comcast.net> Gerard, You will need to set up using: softrock-IF CW Pitch to what ever you set it to Audio IF = 8000 - CW pitch There will need to be a little adjustment of the IF due to your sound card not being exact. You will also need to set CAT to KX3 and appropriate com port. When you get Audio IF set correctly, the frequency readout in the box at the top of skimmer will read your radio's frequency and the little green indicator will be right on the signal you want to read. 73, Barry K3NDM On 7/21/2015 10:08 PM, Scott Simpson wrote: > What settings do you use?

In-Reply-To: References: Message-ID: <55AFED61.1010308@comcast.net> Scott, OOPS! I picked up Gerard in the thread. However, my response of just a few minutes ago is correct. In your case I should have added that you need to set the signal I/O device to the sound card you use for the spectrum display. This way you get more than just the 3 KHz bandwidth you are using and you can use narrow filtering for listening without effecting what skimmer is doing. I hope this is all clear. 73, Barry K3NDM On 7/21/2015 10:08 PM, Scott Simpson wrote: > What settings do you use?

We are a group that provides low cost to FREE straight keys for Young, newly licensed Amateurs who don't have the resources or support to purchase one of their own. At this time we are working with a young man of 17 who is in need of a QRP rig of some sort. More information on our group can be found on the front page of the SKCC homepage. Our group is ready to provide this person with a key, however we do have some regulations that dictate that the recipient must also have some type of working radio and antenna to get on the air. We would like to ask if anyone in this group, or others you know may have a working QRP transceiver that they can donate to the Halfway house for keys program so we can get this young man started on his way with CW. This not only benefits the user, but also benefits all Amateur Radio operators by keeping the CW bands alive. It is very important that we support our youth, as they will be the next generation keeping the bands alive with not only CW but other modes as well. If you can help us help him (and others like him) please contact me off the group so we can arrange something together. Thank you for all your support and help with this matter. 73, Michael N6MQL n6mql at w6sfm dot com (email spelled out to keep spam to a minimum) From rmcgraw at blomand.net Wed Jul 22 18:44:30 2015 From: rmcgraw at blomand.net (Bob McGraw - K4TAX) Date: Wed, 22 Jul 2015 17:44:30 -0500 Subject: [Elecraft] K-Line mounting In-Reply-To: <55AFAA0F.4010201@gmail.com> References: <55AFA3A9.5080108@gmail.com> <55AFAA0F.4010201@gmail.com> Message-ID: <55B01CCE.7070406@blomand.net> I personally use a hard sided travel case fitted with die cut foam to accommodate the various pieces of equipment.......radio, power supply, mike, wire antenna, coax cable, and etc. There's a few dedicated cables and such wired into the travel trailer to assist with getting coax outside.

They have never gone anywhere in hard braking or bumpy roads. Proper cases, to be used anytime the RV is in motion, would be the safe answer. When they start offering K3's as WWII tank equipment, properly hardened for the application, then I will hard mount it in an RV, but not until. I suspect that the KX3 equipment would do better, simply due to the manner of construction. I don't know if anyone has done vibration testing of a KX3, but I suspect it would do better than a K3. 73, Guy On Wed, Jul 22, 2015 at 6:44 PM, Bob McGraw - K4TAX wrote: > I personally use a hard sided travel case fitted with die cut foam to > accommodate the various pieces of equipment.......radio, power supply, > mike, wire antenna, coax cable, and etc. There's a few dedicated cables > and such wired into the travel trailer to assist with getting coax outside. > > Be it a motor home, travel trailer or such, with today's road conditions, > i.e. seams, cracks, and potholes, I wouldn't dare leave my radio on a desk > or table. > > 73 Bob, K4TAX > > On 7/22/2015 9:34 AM, Rick WA6NHC wrote: > >> The question depends on how the rig travels on lousy roads. >> > > > ______________________________________________________________ > 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 k2av.guy at gmail.com > From billjoycek at msn.com Wed Jul 22 19:26:41 2015 From: billjoycek at msn.com (Bill Kastler) Date: Wed, 22 Jul 2015 18:26:41 -0500 Subject: [Elecraft] K3 Intermittent Line Out Audio Message-ID: I have had a problem for a while with intermittent Line Out audio from my K3.

If conductivity = 30 mS ("very good ground") the gain improves to -0.47 dB while the elevation angle lowers to 22 degrees. This is what we expect.?

I never meant to suggest something crazy like that one not use radials; I only wanted to point out a peculiar characteristic of verticals above real ground. I will re-state my original thesis this way: If you have perfectly conducting ground, there is no ground loss. If you have perfectly insulating ground, there is no ground loss. There's always some ground conductivity in between those extremes at which the loss is maximum. This value depends on the frequency. ?

I will re-state my original thesis this way: If you have perfectly conducting ground, there is no ground loss. If you have perfectly insulating ground, there is no ground loss. There's always some ground conductivity in between those extremes at which the loss is maximum. This value depends on the frequency.

This humble arrangement of wires radiates somewhere along a continuum between "vertical with one or more radials" (over perfect ground) and "inverted V mounted at a weird angle" (in free space). I think that explains the variance in loss, takeoff angle, etc. Most portable antennas live between these two extremes. Your analysis proves the operator is better off enjoying the effect of radiation than obsessing over its shape.

I was running firmware version 4.58 so I thought I'd better update it in readiness for the new arrivals. The computer I use for radio is 32 bit running Win98se, it works very well with my homebrew logging program which integrates with the K3. I did try porting it to WinXP but met with problems, "if it ain't broke don't fix it", so stuck with 98se. This computer dual boots to Linux Mint12, which runs K3utils. My internet computer is 64 bit and dual boots Win7 and Linux Mint17. I use Mint17 for all internet work so I downloaded the Latest Linux K3utils (1_14_10_24) and installed it, I tried to run it nothing happened. After a session of 'Googling' I found that K3utils is 32 bit and needed 32 bit files loading to make it run on a 64 bit machine, I decided against this and downloaded all the .hex files, transfering these to Linux Mint12, connected the K3, and tried running the Util. It could not find the port displaying the message 'access denied'. After trying various things, without success, I went 'Googling' again, this time I found the problem was, as the User, I wasn't a member of the group 'Dialout', which gives access to serial ports on Linux, on joining this group the Util now worked OK. It was Sunday afternoon with time to spare before my evening meal, I decided to bite the bullet and run the upgrade to 5.29. I had not updated the firmware for a while and could not remember how long it took. Off it went, my meal was ready and still it churned on and seemed to be running slower and slower, I left it, had my meal and came back to find it was still plodding on. It took 4400 seconds according to the display on the Util. With fingers crossed I turned the K3 off and on again, yippee it worked, very much to my relief, in view of some of the problems posted on the reflector. The newly ordered parts arrived and were duly installed. I had to run the K3util to install the firmware for DSP2, this took 2200+ seconds, is this normal for firmware loading? All is working FB, and getting to grips with listening to different stations in each ear!! If anybody else has the same or similar problems, I hope in some way this helps, If nothing else it might have caused a chuckle or two.

Clearly, as your ground gets really bad your antenna can still work just fine, even better in some cases! Hi Al, Several observations. First, soil influences vertically polarized antennas in two ways. First, loss in the soil near the antenna as the field from the antenna causes current flow in the ground. The result is simple I squared R loss, and that power does not get radiated. Second is the reflection from the earth in the far field where the radiated field hits it. That reflection adds (algebraically) to the direct signal to form the vertical pattern. The strength of the combined direct signal plus reflected signal depends on the relative phase angle between them, which in turn is a factor of distance, the elevation angle, and the soil. The second point is that conductivity is not the only soil parameter. There is also the dielectric constant. In EZNEC, if you open the Ground Description tab and right click on either Cond or Diel Const, you'll get a window showing a continuum of soil types from very good to very poor. BOTH Cond and Diel Const vary with those soil types, and both quantities affect how the antenna behaves. A year or two ago, I did an extensive study of the interaction of vertically polarized antennas with soil of different types and at different mounting heights. I presented it to the Pacificon Antenna Forum using these slides. http://k9yc.com/VerticalHeight.pdf 73, Jim K9YC From w3fpr at embarqmail.com Thu Jul 23 12:39:42 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Thu, 23 Jul 2015 12:39:42 -0400 Subject: [Elecraft] [K3] KXV3B - No missing pin In-Reply-To: <138569D829754837B804597A20706D21@GeoffreyPC> References: <138569D829754837B804597A20706D21@GeoffreyPC> Message-ID: <55B118CE.2080303@embarqmail.com> Geoff, Look at the mating female connector.

Yes, I know you don't need that sort of power for digital modes, but it does eliminate the need for a bigger heat sink on the KX3 and it upgrades the KX3 in case you want to run power on SSB or drive a larger amp to get heard in DX pileups.

Consider a "ground plane antenna" with the base mounted at the rooftop of a 1 or 2 story building - it is reasonably independent of near field ground conditions because it is an antenna within itself - much the same as a vertical dipole. A vertical with buried radials is quite dependent on ground conductivity unless the number of radials is large. The far field ground conditions still do play a part and what Jim has pointed out below is valid. IMHO, the main advantage of a vertical is that it has a null at the top of the elevation plots which will reduce the response to high angle reception (nearby stations). If you look at the elevation plot for a horizontal dipole along with a vertical, you will see that the dipole has almost as much gain at low angles as the vertical - so from a pure gain standpoint, the vertical offers no advantage. BUT that is comparing a vertical with a high dipole (at least 1/2 wavelength high). For the lower frequency bands, the height of a dipole with those characteristics is not practical for most hams and the vertical wins "hands down" for DX - provided a good radial field or elevated radials are used. 73, Don W3FPR On 7/23/2015 11:10 AM, Jim Brown wrote: > On Wed,7/22/2015 6:15 PM, Al Lorona wrote: >> This suggests that ground loss is sort of an impedance-matching >> problem.

If you're on a pointy part of the Earth [aka summit such as in SOTA], the far field effects can and often do lower the max elevation angle to or below the apparent horizon. Most antennas on summits exhibit a host of other inefficiencies as well, but the effect is there. I used a vertical GP with my Buddipole on summits only because the horizontal OCF loaded dipole configuration was worse. One thing that hasn't been mentioned is noise on RX. It seems like the preponderance of man-made noise is vertically [more or less] polarized. Until last Sunday, I had a Gap Titan on the roof. Good antenna, very low SWR on all its bands. Nearly all the time, noise was 1-3 S-units higher than on my tribander or dipoles. I did keep checking because occasionally, mainly on 12 and 10, it was lower than the TB. Man-made noise may not be a problem in a remote, back-packing environment of course. 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 7/23/2015 4:30 PM, Don Wilhelm wrote: > For the lower frequency bands, the height of a dipole > with those characteristics is not practical for most hams and the > vertical wins "hands down" for DX - provided a good radial field or > elevated radials are used. > > 73, > Don W3FPR From w7hd at msn.com Thu Jul 23 20:07:08 2015 From: w7hd at msn.com (w7hd at msn.com) Date: Thu, 23 Jul 2015 17:07:08 -0700 Subject: [Elecraft] Atmospheric noise increases Message-ID: <55B181AC.1050508@msn.com> Has anyone else noticed the dramatic increase in atmospheric noise lately?

The noise will vary from an S3 up to a 20/S9. It is especially troublesome on the frequencies I use most, namely, 10.1389, 14.045, 14.070, 7045, and 7070. With the antenna disconnected, the noise drops to S1 or less. I use 3 different antennas, a Force-12 15 ft vertical about 50 feet from the house, a homebrew 25 ft flagpole vertical about 30 feet away and an inverted vee for 40M on the tower adjacent to the house fed with 450-ohm ladderline to a 4:1 balun at 50 feet.

Especially if it drifts up and down slowly. Odds generally are that it's correlated with the slowly increasing use of LED and CFL lights ... and possibly increases in "indoor agriculture." The latter can generally be identified by a fairly strict schedule of on and off.

The source of this noise is not in my house.....but could be a neighbor's. You noted that your noise level drops to S1 when that source is not there? When I see a steady but slowly moving "hump" on the P3 display my noise floor remains about the same but at S2.5 or so on 20 meters during the day. I'm two blocks from a shopping center, population of Lawrence is 100,000. I've been able to drop that noise floor, thus increasing S/N by nearly 3 S units, using a 20-meter beverage antenna (one wavelength due to short back yard) and attaching it to the AUX BNC input of my K3 for diversity reception. To that I've started using the K3's built in APF filter during CW op to improve listening too. If you'd like a copy of my Power Point presentation on this setup (given to my local club), I'd be happy to email it back to you.

But I do work with Windows because it will do some things I need (much better for working with DVDs for example -- and more ham radio apps). So some time ago I installed Windows 10 Preview on my Win 8.1 machine (my main Windows computers are Windows 7, and will stay that way for a while, at least). Windows 10 is an improvement over Win 8.1, IMO -- and that's even after modifying Win 8.1 to make the GUI work like Win 7 :-) 73, Phil W7OX On 7/24/15 7:22 AM, kg9hfrank at gmail.com wrote: > Bill you are not alone as a MAC user and I am NOT going to purchase a WIN 10 box to do any work for ham radio. > > I have used the utility on my MacBookAir for the KX3 utility and love it. > > Frank KG9H > > >> On Jul 24, 2015, at 9:17 AM, Bill Conkling wrote: >> >> >> I have been using my K3S with Win 7 so far and decided to give the Mac a chance to play. >> >> Downloaded the latest utility for the Mac (Latest OSX, Macbook Pro I7 w/16gigs) and convinced the Mac that I really did want to open this file.

This is to make sure that miscellaneous, not on purpose, states of DTR and RTS in the serial connection are not controlling the transmit and keying state of the K3. I'm not qualified to discuss how to turn off DTR and RTS on a Mac from the operating system. Better to set the K3 to not respond to those. Commonly, if used, DTR and RTS are controlled by applications running on the computer using a serial port to talk to the K3, but the state of those absent a program controlling them is unclear. N1MM logger and logger plus have a config setting to set up DTR and RTS for use or to force them to a given state. If you DO at some point decide to use DTR and RST for keying and/or PTT, you will have to completely understand and control those lines coming from the computer, be they Windows or Apple. Otherwise they should both be turned off in the K3 config. DTR and RTS are part of any serial connection, so this would be true as well using the new USB connection for K3/K3S. The DTR and RTS information from the computer still must either be managed or turned off in the config. The K3 manual version D10 has a discussion of these pinouts on page 18. 73, Guy.

Apple provides a driver for FTDI-based USB-serial devices. That driver unconditionally asserts DTR and ignores attempts by applications to turn DTR off. When you install the FTDI-provided driver, it takes precedence over the Apple driver and behaves more responsibly. I filled a bug report about this; Apple marked it as a ?duplicate? and closed it.

You'll also need a KXV3 (any type), because you have to the low-level transmit signal from the XVTR OUT jack, not from the main antenna jack. (The main antenna path has a pretty steep high-pass response to protect the PIN diodes in the T/R switch.) Assuming you have the above in place: 1. Tune the VFO to the desired frequency (say 472 kHz) 2. Set CONFIG:KXV3B to TEST (this selects the XVTR IN/OUT jacks) 3. Set power output to 1.0 mW with the POWER control You will of course need an external amplifier of some kind, and depending on how it is configured, you might also need a T/R path splitter to get the RX signal to XVTR IN. 73, Wayne N6KR On Jul 24, 2015, at 3:38 PM, John Klewer wrote: > I likely just missed it but wondered if anyone knows how to enable transmit > on my new-synthesizer-equipped K3 in the 630 Meter band. > > My transceiver indicates "BND END" when attempting transmit. > > It may be that the firmware has not yet been modified as the band has not > yet been approved by the powers that be.....thanks for info (if available) > > John, N6AX > ______________________________________________________________ > 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 n6kr at elecraft.com From scott.manthe at gmail.com Fri Jul 24 20:08:28 2015 From: scott.manthe at gmail.com (Scott Manthe) Date: Fri, 24 Jul 2015 20:08:28 -0400 Subject: [Elecraft] 200 Hz 5-pole filter In-Reply-To: <55B2C7D7.8030200@aol.com> References: <55B2C7D7.8030200@aol.com> Message-ID: <55B2D37C.3000007@gmail.com> I noticed this as well.

In my case I have a 3-pound bag ready to go at all times that includes: - the KX3 with internal ATU, KXPD3 keyer paddle, 2-meter module, and MH2 mic - 8 NiMH batteries inside the case and 8 spares - two 25' lengths of #26 insulated antenna wire ("Silky," from The Wireman) - an assortment of collapsable whips, adapters, small wire antenna weights, etc. - a small paper logbook. If I'm expecting to sit on the ground in wet conditions I also bring a 1x1 meter ground cloth. This all fits comfortably in a ThinkTank "Strobe Stuff" bag. Don't forget your water bottle :) 73, Wayne N6KR On Jul 24, 2015, at 5:11 PM, jonlevy73 wrote: > Does anyone have a go kit built around a KX3 for HF operations? > > KH6AUX > > > > -- > View this message in context: http://elecraft.365791.n2.nabble.com/KX3-go-kit-tp7605302.html > Sent from the Elecraft mailing list archive at Nabble.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 n6kr at elecraft.com From alsopb at nc.rr.com Fri Jul 24 20:21:14 2015 From: alsopb at nc.rr.com (brian) Date: Sat, 25 Jul 2015 00:21:14 +0000 Subject: [Elecraft] 200 Hz 5-pole filter In-Reply-To: <55B2D37C.3000007@gmail.com> References: <55B2C7D7.8030200@aol.com> <55B2D37C.3000007@gmail.com> Message-ID: <55B2D67A.9090101@nc.rr.com> This filter was my secret weapon when the going got tough-- especially on 160/80/40 M during contests.

I recently changed my laptop and succeeded in finding a laptop with a RS232 com port (HP ProBook 650 G1). The problem I'm now facing is that normal DB9 female connectors cannot be reliably inserted in the male DB9 connector of the laptop due to the physical characteristics of the male DB9 connector : there are no nuts on the laptop to attach the connector and the height of normal DB9 female connectors is too big. I looked at many supplier web pages but didn't find a thinner DB9 connector without bolts. Has anybody made the same experience and resolved the problem ?

However, I can say that my "experience" tends to confirm a lot these findings. First, I originally had an R7 vertical ground mounted. Performance was "O.K.", but certainly not very exciting. Later I elevated that antenna to about 15 ft. above ground, and the improvement was very noticeable. Subsequently I have replaced the R7 with an F8 (acquired in an estate sale), and the results are very much the same--the antennas are not all that much different anyway, but the R8 is a bit taller, and does cover 6 meters (after a fashion!). If you look at the study Ward Silver, N0AX, did many years ago on various vertical antenna systems, the R8 is rated one of the very best. In any event, I've worked well over 100 countries QRP on 40 meters using this arrangement. After hearing Rudy Severns' presentation about ground systems at Pacificon several years ago, I began elevating radials when using my portable antenna systems while camping. Most of this was done using either an MP-1 or a Biddipole configured as a Buddistick. Again, the results were very rewarding. As Rudy indicates, elevating your radials even just a small amount can result in significant benefit. Usually I try to deploy 4 elevated radials. Sometimes, though, only 1 or 2 are practical under the circumstances. Still, it helps! I also acquired a used Sigma 40XK, and now use it as my primary 40 meter antenna at home. That antenna is raised about 6 feet off the ground, so the overall height is about 20 feet or so. I wish I could go higher, but neighborhood restrictions prevent that. I get a 1 to 3 Db improvement with this antenna over the R8, measured by comparisons using the RBN system. I've become a big fan of vertical dipoles! When I go QRO (500 watts for me), I get some reports from DX stations that I consider to be exceptional. I also monitor myself on the RBN, so I have some idea as to who might hear me and who can't. It's almost better than trying to interpret some of the propagation software. I also have one of N6BT's Bravo 7 antennas, which he calls vertical dipoles also. By the way, N6BT also designed the Sigma 40KX when he owned Force 12. Anyway, the Bravo 7 works pretty well as a portable system, but I'm not quite as happy with it as a 40 meter system. Still, it is very portable, and easy to put up and take down. N6BT makes some pretty aggressive claims about the performance of this system, but I am pretty sure most of his "testing" was done over salt water. In any event, the higher up I deploy that system, the better it seems to work. I think Jim Brown's suggestion of adding a better radial system to vertical dipoles may be exactly what I need to try and do with the Bravo 7, particularly for 40 meter operation. Soil conditions here in Arizona are pretty awful. It's not very often that I go camping anywhere that offers anything much better. Deploying elevated radials can be problematic, but it certainly seems worth the effort most of the time.

Meanwhile, the 400-Hz and 250-Hz filters also do an excellent job. As I've mentioned before, any radio with 2-kHz IMDDR3 numbers in the 100-dB-plus range is going to be a solid performer on the air. A dB here or there above this level is really splitting hairs; it speaks more to an engineering achievement that a required level for most operators. That said, we're happy to have two of our radios in Sherwood's top four, especially when you consider the difference in price. And if you take blocking dynamic range into consideration, as well as the various footnotes, the K3S is second to none. 73, Wayne N6KR From bill at wjschmidt.com Sat Jul 25 16:01:04 2015 From: bill at wjschmidt.com (Dr. William J.

IMDDR3 is the difference between the input RX sig levels that created the IMD and the MDS of the RX. It may increase IMDDR3 slightly, or even reduce it, depending on which RX stages go into distortion at high levels first. But who wants a deaf RX that can not hear down to the noise floor of the band? What turning on the attenuator (or having a poor sensitivity RX) -does- do is artificially increase the iP3 number, rendering it meaningless as a number for comparing different receivers which have -different- RX sensitivities for that measurement. Some manufacturers have gamed this number for years. For best comparisons, receivers should be compared at the same sensitivity level.

The point is that there isn't going to be much difference between the 250hz 8 pole filter and the 200hz 5 pole filter. But think about your comment for a moment. A stock K3 with no additional filters is that good enough to rank that high. It might actually rank higher, because the ARRL and Sherwood methodologies differ. In any case, far too many people are far too concerned about the Sherwood rankings. Most people don't understand what the data mean and only worry about where a radio ranks on the list. The few dB between radios at the top of the Sherwood rankings means the list could probably be reordered based on component differences in production runs. Certainly a radio near the top ten is good enough. 73, Scott N9AA On 7/25/15 3:29 PM, XE3/K5ENS via Elecraft wrote: > That is not the Sherwood "receiver list" that everyone covets. > > Taking this data the K3 would be about 11th or 12th on the list > with the stock 2.7hz filter. > > > > -- > View this message in context: http://elecraft.365791.n2.nabble.com/200-Hz-5-pole-filter-tp7605299p7605328.html > Sent from the Elecraft mailing list archive at Nabble.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 scott.manthe at gmail.com > . > From jim at audiosystemsgroup.com Sat Jul 25 16:22:20 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Sat, 25 Jul 2015 13:22:20 -0700 Subject: [Elecraft] OT: Ground Loss (long) In-Reply-To: References: Message-ID: <55B3EFFC.8060409@audiosystemsgroup.com> On Sat,7/25/2015 10:16 AM, dyarnes wrote: > I also have one of N6BT's Bravo 7 antennas, which he calls vertical > dipoles also.

I've not known Tom to "puff" his antennas with exaggerated claims. He's a very good designer, and my experience with him is nothing but honesty. It is, however, well known that verticals work awfully well over salt water, and he's written extensively about that. > In any event, the higher up I deploy that system, the better it seems > to work.

After having done some more modeling, I'm backpedaling on that suggestion. You'd need a LOT of radials over pretty awful ground to see a dB or so. Note also that the horizontal elements at the bottom of Tom's vertical dipoles are NOT radials, they are capacitive loading for the bottom half of the dipole. Don't try to add to them -- you'll detune the antenna. :) 73, Jim K9YC From kl7uw at acsalaska.net Sat Jul 25 17:52:38 2015 From: kl7uw at acsalaska.net (Edward R Cole) Date: Sat, 25 Jul 2015 13:52:38 -0800 Subject: [Elecraft] K3 Setup for TX at 630 Meter Band Message-ID: <201507252153.t6PLrXTb008516@mail40c28.carrierzone.com> John, Wayne covered the technical aspects of transmitting on 630m, but there are legal aspects that all newbies with K3s and upgraded K3's should be aware. There is NO HAM BAND on 630m so your ham license is invalid for transmitting on those frequencies (FCC promises someday - don't hold your breath). The only way to legally transmit is to obtain an experimental license from the FCC for use of 630m. I am not prepared to walk you thru that - just saying its a lot more involved than a ham license. If really interested in getting on before amateur radio is approved, I suggest you get in touch with the ARRL Experimental Group: http://www.500kc.com/ ARRL has just submitted renewal of our license: WD2XSH.

I wonder if anyone else has thought about this? You can buy manual RJ-45 switches on Amazon. I just ordered one to try out. 10 bucks plus shipping: http://www.amazon.com/Network-Output-Manual-Sharing-Switch/dp/B00AUB3SSA/ If you wanted it to switch automatically you could probably modify one of these boxes with your own relays and decoder circuit, or just build one from scratch. There are 8 pins on the connectors. Power and ground (pins 1 and 3) don't need to be switched: just wire all in parallel. VSCL (pin 4) is not used in the P3 and can be left disconnected. So for each sensor you'd need one 5PST relay to switch SCALE, SENSE, VREF, VFWD and VREV (pins 5, 7, 8, 6 and 2 respectively.

In the normal situation where it is monitoring the IF output of a receiver, it is limited to 24 kHz. You can "fool" Skimmer into thinking it is a fixed-tune receiver, but performance is likely to suffer unless the receiver is parked on one frequency.

Just wire the K2 microphone jack for the Elecraft configuration and re-wire the microphone plugs for that pinout. OTOH, if you still have transceivers that use those microphones and cannot easily re-wire the mic plugs, then the IMA makes sense if you want to swap the mics around. Most hams pick one microphone and use it with the K2, so there is normally no need to swap the IMA connections - just wire the normal K2 microphone configuration for the chosen microphone.

I pick those two power outputs because with typically inefficient antennas on 630m 25w => 1w ERP and 100w => 5w ERP (approx). These two ERP are mentioned in the WARC-12 band approval and FCC as possible max allowed power levels. Currently the ARRL Experimental Group is approved at 20w ERP but there are not many stations running that in the group. I run 100w with 0.1mw drive from my K3 for approx 3w ERP. 1mw is typical output for mixers so the amp would be usable by low-power transverters, as well. I am wondering what kind of interest there would be for a linear amp that could be driven by the K3s/K3? I would probably have an optional Rx preamp in such a package. No idea of cost at this juncture as its just in "maybe status". Wayne has stated to me that Elecraft is not intending to build such due to the limited market. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From breedenwb at cableone.net Sun Jul 26 17:02:21 2015 From: breedenwb at cableone.net (Bill Breeden) Date: Sun, 26 Jul 2015 16:02:21 -0500 Subject: [Elecraft] 200 Hz 5-pole filter In-Reply-To: References: Message-ID: <55B54ADD.9060100@cableone.net> Since Sherwood's Dynamic Range Narrow Spaced measurement is of great interest to CW operators, it only makes sense to make the measurement using a CW filter, optional or not.

The plug-in filters are additional roofing filters that protect the DSP from overload by strong signals outside of their passband. The K3, K3S, and KX3 have very good CW receivers without the optional roofing filters. The roofing filters simply allow them to work very close to very strong signals, AND cascade with the DSP filter to provide additional rejection outside the passband. 73, Jim K9YC From breedenwb at cableone.net Sun Jul 26 18:41:24 2015 From: breedenwb at cableone.net (Bill Breeden) Date: Sun, 26 Jul 2015 17:41:24 -0500 Subject: [Elecraft] 200 Hz 5-pole filter Message-ID: <55B56214.80504@cableone.net> Jim, I disagree.

Hi Bill, That point is not lost on anyone, and is the reason that serious contesters use narrow roofing filters. I said exactly that in my earlier response. But the point that you are missing is that the K3, K3S, and KX3 are complete radios with the stock 2.7 kHz 5-pole or 2.8 kHz 8-pole roofing filters, and are comparable to the receivers we have used for as long as I have been a ham (60 years). What's different are 1) the some of the hardware with which those older radios and the K3/K3S/KX3 are built. Our older receivers used physical coils and capacitors in the IF, while these newer ones simulate those Ls and Cs in DSP; 2) the system architecture that Wayne developed (for example, his choice of IF frequencies, his methods of reducing phase noise, keying transients, etc.; and 3) they're a lot better radios that most of those older ones. A ham who doesn't participate in major contests is unlikely to need anything more than the 2.7 or 2.8 kHz roofing filter. 73, Jim K9YC From tom at nilza.org Sun Jul 26 21:57:55 2015 From: tom at nilza.org (Tom Azlin W7SUA) Date: Sun, 26 Jul 2015 18:57:55 -0700 Subject: [Elecraft] K3: 630m amplifiers In-Reply-To: <55B57EAF.4000502@sonic.net> References: <201507262023.t6QKN8cc024977@mail40c28.carrierzone.com> <55B57A70.3020903@nilza.org> <55B57C22.4060408@embarqmail.com> <55B57EAF.4000502@sonic.net> Message-ID: <55B59023.4060601@nilza.org> Hi Don and Alan, I was thinking one of the slow multi tone FSK modes that are a single tone at a time.

The problem is that neither of those signals are continuous -- both are changed to convey information. Mother nature recognizes a keyed CW waveform as a square wave modulating a carrier. Any waveform more complicated than a continuous carrier has multiple components, and in the case of a square wave or impulse, an infinite number of them. If that waveform is passed through a non-linear amplifier, distortion will be produced. There will be both harmonic and intermodulation distortion. Take a look at slides 13 and 15 in http://k9yc.com/FTDX5000_Report.pdf. Slide 13 is a continuous carrier. The sidebands at -48dBC are probably hum. Now look at Slide 15, which is the same radio transmitting a series of dits. I haven't measured an un-keyed K3 yet, but I suspect it's cleaner, especially with the new synth board. I may get to that this week. Several years ago, some of the serious engineers running RTTY noticed that the K3 running FSK wasn't as clean as when running AFSK. Wayne and the crew did some serious work on the firmware and it's now better. 73, Jim K9YC On Sun,7/26/2015 6:57 PM, Tom Azlin W7SUA wrote: > I was thinking one of the slow multi tone FSK modes that are a single > tone at a time.

No, CW requires a linear amplifier. CW is not constant-amplitude - the amplitude changes every time you open or close the key. A class-C amplifier would mess up the key shaping, causing key clicks. Any true FSK or MSK signal should not be bothered by a non-linear amplifier. The only caveat I can think of is that the amplitude of an AFSK signal may have some ripple on it to the extent that the passband of the transmit crystal filter is not flat. But I doubt that's a significant issue.

I produce some models of amplifiers, of different powers, all in switching operation. Here an image of the DK7FC grabber, you can see at 472.1 KHz the spectrogram of a German station that use a class D amplifier, at 472.5 an Italian station that use a 400W tube linear amplifier and at 473.3 there is my signal with my QRO+ switching PA. https://www.dropbox.com/s/oziocm3vshfftgl/19012015.JPG?dl=0 I can assure that I often find local stations operating at 250-300 Hz from my frequency that are not minimally disturbed I do not think that a linear amplifier is so better. I also made a 100W output amplifier specifically designed for the K3. This amplifier runs at 12 volt. All my PA need an input signal (adjustable) from -10dBm to + 20 dBm https://www.dropbox.com/s/u2yjp0ltv0kbsy5/K3%20and%20Pa.jpg?dl=0 73, Fausto IK4NMF From k2vco.vic at gmail.com Mon Jul 27 05:35:16 2015 From: k2vco.vic at gmail.com (Vic Rosenthal 4X6GP/K2VCO) Date: Mon, 27 Jul 2015 12:35:16 +0300 Subject: [Elecraft] K3: 630m amplifiers In-Reply-To: <55B5B45C.7070307@sonic.net> References: <201507262023.t6QKN8cc024977@mail40c28.carrierzone.com> <55B57A70.3020903@nilza.org> <55B57C22.4060408@embarqmail.com> <55B57EAF.4000502@sonic.net> <55B59023.4060601@nilza.org> <55B5B45C.7070307@sonic.net> Message-ID: <55B5FB54.6090204@gmail.com> A CW amplifier can be designed to run class-C but to be keyed in such a way as to pass through the linear portion of the amplifying device's curve when a CW element is starting or ending, in order to preserve the shaping. A simple example is the tube-type amplifier that has just enough fixed bias applied to allow a small amount of plate current to flow (class AB), with a grid resistor that provides the rest of the bias as a result of rectified grid current as the drive ramps up. At full power the tube is running class C with bias way beyond cutoff. Good 1950's technology that can be made a little more sophisticated and applied today! 73, Vic, 4X6GP/K2VCO Rehovot, Israel http://www.qsl.net/k2vco/ On 27 Jul 2015 07:32, Alan wrote: > > > CW would be another mode that would not need a linear amp I think. > > No, CW requires a linear amplifier.

It's easy enough to spin VFO A to get to the right band and mode, then tune from there. Most of the programmed freqs are "watering hole" type frequencies. For example, the four memories on 30m are: Showing VFO A and b - 21: 10.100, 10.110 CW 22: 10.106, 10.116 CW 23: 10.1406, 10.1387 Data A (PSK typical center and WSPR) 24: 10.1415, 10.1425 Data A (Olivia watering holes) For the remainder, I have a bunch of Army MARS freqs, some SWL band centers, a few AM stations, and WWV/CHU, etc (utility freqs) and so on. Anyone can do pretty much the same thing with the M1 - M4 quick memories. I just like general memories little better, because recall causes the band change without a separate action. 73, matt W6NIA On Mon, 27 Jul 2015 12:10:37 +0000, you wrote: >I wonder how you guys with 100 programmed memories manage to remember >what is in what memory? >Personally if the number gets to be greater than 5, I have no clue.

Also the linear amplifier at 472.5 KHz in the spectrogram shows key clicks but lower. On the other hand you can see that my signal at 473.3 is very clean without key clicks. Many hams have asked me how it is possible that with a switching amplifier there are no key clicks. The answer is that I have taken a different approach by the schemes that are on web and the result you can see yourself. It is very important to dampen all transients during switching from interdiction to conduction and vice versa. I had to work a lot but at the end I got a very clean TX. 73, Fausto IK4NMF ----- Original Message ----- From: "Alan" To: "Fausto Coletti" Sent: Monday, July 27, 2015 5:21 PM Subject: Re: [Elecraft] K3: 630m amplifiers > Hi Fausto, > > The term "class D" can mean many different things.

CW, JT65, FSK all do fine with class-C, of course. And its true that any modulation of a continuous carrier will impart some bandwidth. Its not likely that wide-band digital modes will be approved in a band that is only 7-KHz wide so probably those approved would work with a class-C amp. I think its just simpler to provide class-AB then its a non-issue. Re: 15-dB HF linear amp gain limit. If that is applied to 630m amps then either I sell a kit or partial kit. 1mw in to 1w out is 30-dB and 100w out is 50-dB. I would have to research the regs to see if the limit is for a certain level of input (like 5w). Also the regs allow hams to sell amps to other hams without this restriction (but at what quantity per year?). First off I am not proposing to go into competition with MFJ. This is just a home business building one at a time. If the FCC is going to make this a small (tiny) business killer than its just not worth the bother. If I say more than this it will get political and that is OT. 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From jim at audiosystemsgroup.com Mon Jul 27 14:42:56 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 27 Jul 2015 11:42:56 -0700 Subject: [Elecraft] K3: 630m amplifiers In-Reply-To: <201507271744.t6RHhwG7021578@mail41c28.carrierzone.com> References: <201507271744.t6RHhwG7021578@mail41c28.carrierzone.com> Message-ID: <55B67BB0.7040307@audiosystemsgroup.com> On Mon,7/27/2015 10:43 AM, Edward R Cole wrote: > CW, JT65, FSK all do fine with class-C, of course.

Grid-block keying was all the rage for help in shaping the keying envelope. Cathode keying was used too, but usually not with keying. You had to be careful the key did not "bite" from the voltage on it. 73, Don W3FPR On 7/27/2015 4:27 PM, Phil Wheeler wrote: > I'd have to dig out my old circuit diagrams, but it seems like when we > used Class C amps "back in the day" (1950's and 60s) we keyed the > output stage, not only the driver as with linear amps -- and we > modulated the output stage in the AM days, too. > > 73, Phil W7OX > From n1al at sonic.net Mon Jul 27 16:53:34 2015 From: n1al at sonic.net (Alan) Date: Mon, 27 Jul 2015 13:53:34 -0700 Subject: [Elecraft] K3: 630m amplifiers In-Reply-To: <55B67BB0.7040307@audiosystemsgroup.com> References: <201507271744.t6RHhwG7021578@mail41c28.carrierzone.com> <55B67BB0.7040307@audiosystemsgroup.com> Message-ID: <55B69A4E.90400@sonic.net> The need for linear amplifiers with CW has been known for many years. Quoting from the 1964 ARRL Handbook: When key clicks introduced by the addition of an amplifier stage are found only near the transmitter frequency, amplifier "clipping" is indicated. It is quite common when fixed bias is used on the amplifier and the bias is well past the "cut-off" value. [In other words, a class C amplifier. Similar to a bipolar transistor amplifier with no base bias.] A linear amplifier (Class AB1, AB2 or B) will amplify the excitation without adding any clicks, and if clicks show up, a low-frequency parasitic oscillation is probably the reason.

Hi Joe, We have shipped a few dozen, but some have not been received yet, and probably half were kits, which take longer to come on-line. Some of those received have already been mentioned on this forum, or on the Yahoo group (search for "K3S" in the archives). But only a small percentage of our customers participate in the forum at any given time. In addition to forum comments, the first customer to post an eHam review of the K3S created a product category for it: http://www.eham.net/reviews/detail/12433 There are two reviews so far, both very thoughtful (and long -- proceed with caution :) We're of course very happy to see so many positive comments. There are also a few minor negative points, typical of any product. We take these as constructive input toward future improvements. One reviewer with a very sensitive sense of touch (speculation on my part) commented that he could feel the felt pad under the VFO knob. This pad is intended to create drag, and the amount of drag is adjustable. But, haptics being in the fingers of the beholder, I emailed him to discuss hypothetical alternatives. I'm sure there will be additional postings and reviews soon. Meanwhile, we're working out a few last annoyances in our shipping procedure in hopes of shipping more quickly. We'll also have a new firmware release for the K3/K3S this week. 73, Wayne N6KR From n9tf at comcast.net Mon Jul 27 17:50:00 2015 From: n9tf at comcast.net (n9tf at comcast.net) Date: Mon, 27 Jul 2015 21:50:00 +0000 (UTC) Subject: [Elecraft] New K3S In-Reply-To: <41F0DAFA-ACA9-4517-A89C-8F2E88779520@bellsouth.net> References: <41F0DAFA-ACA9-4517-A89C-8F2E88779520@bellsouth.net> Message-ID: <1904098840.18201113.1438033800055.JavaMail.zimbra@comcast.net> Hi Joe, ? I received my K3S last week SN 10057. I cannot give you an A-B comparison against the original K3 as I never had one. One thing I can comment on though A to B,?is about the speaker audio between the K3 and K3S as I was exposed to several K3's at field day. The speaker audio is MUCH cleaner with better gain and no distortion. I am running the speaker out to a pair of Polk book end speakers (passive)?from a surround sound entertainment system. Very clean audio. The internal speaker also presents a very clean, loud, undistorted quality. Any other comparisons would be compared against my previous Icom ProIII, which so far is night and day! I have the following roofing filters set up. 6Khz, 2.7Khz, 500hz and 250hz. I am amazed at how tight this receiver is with these roofing filters, and the flexibility of all RX options compared to what I was using. With regard to the preamps, I can only compare to ProIII, and the S/N? with pre amp 1 or 2 in has a much higher signal level?to noise floor increase. Very clean. ? I am still in the learning mode at this time! ? 73 Gene, N9TF ?

So much detailed thought goes into packaging, the assembly manual, and of course, the style and design. If you?re new to Elecraft and you?re exploring building a kit, just know you are expertly guided through the build process by thee best people in this business. I do admit I confused a 4.0mm spacer with a 4.8mm spacer, but that was in hour 7 of the build. I?ll forgive myself for that! :?) Five stars people. Bravo, bravo, bravo.

In all the old handbooks the discussion of amplifier design says ( page 76, 1941) "In amateur transmitters, and r.f. amplifier is invariably operated Class C ( see Chaptr 3)." I though the final tuned circuit was simply "pulsed" at the RF freq and then the output filtering knocked off harmonics leaving a clean CW note. And in the article on construction of a 100-175 watt CW transmitter ( page 155-157) the 6L6 crystal oscillator was cathode keyed with a bit of RC shaping. Rest of stages powered up when in transmit. And I thought these days some AM broadcast transmitters operated Class E. Clearly not linear. 73, tom w7sua On 7/26/2015 9:32 PM, Alan wrote: > > > CW would be another mode that would not need a linear amp I think. > > No, CW requires a linear amplifier.

So the key shaping was not degraded by a subsequent amplifier. It's OK if the PA is a class C amplifier as long as the key shaping circuit takes that into account. One way to get away with using a separate class C amplifier it to use a two-stage grid bias circuit. A fixed voltage biases the tube so that it draws a little resting current (like a linear class B amplifier) and the rest of the bias is developed from a grid-leak resistor, which only kicks in when RF is applied to the input. So as the RF input ramps up at the beginning of a dit, there is no abrupt transition from off to on. It still increases the slope of the rise and fall, so it does increase key clicks, but not as bad as with pure fixed bias. You can compensate by slowing down the rise/fall times of the key shaping circuit.

Yes, the tank of a class C amp is pulsed and the output network kills the harmonics. But it does NOT kill the intermodulation distortion that is produced by the non-linearity, and that intermod is heard as clicks. BTW -- you need a MUCH newer Handbook. :) 73, Jim K9YC From w7ox at socal.rr.com Mon Jul 27 20:32:23 2015 From: w7ox at socal.rr.com (Phil Wheeler) Date: Mon, 27 Jul 2015 17:32:23 -0700 Subject: [Elecraft] K3: 630m amplifiers In-Reply-To: <55B69A4E.90400@sonic.net> References: <201507271744.t6RHhwG7021578@mail41c28.carrierzone.com> <55B67BB0.7040307@audiosystemsgroup.com> <55B69A4E.90400@sonic.net> Message-ID: <55B6CD97.9090005@socal.rr.com> Clearly you are not among those who reminisce about the rotary spark gap, Alan :-) 73, Phil W7OX On 7/27/15 1:53 PM, Alan wrote: > The need for linear amplifiers with CW has been > known for many years.

To operate the KPA100, it needs the base K2 MCU to change bands, do T/R switching, and monitor the power output (among other things). Those functions depend on the signals to and from the base K2 MCU. The same is true of the KAT100 mounted in your EC2 enclosure. So yes, the KPA100 can operate as an amplifier, but would need a lot of external control signals. If you are willing to create a digital interface that will provide the proper control signals to the KPA100, then you could make it work, but the expense and trouble to get that working would exceed the price of the KXPA100. 73, Don W3FPR On 7/27/2015 8:00 PM, kg9hfrank at gmail.com wrote: > Squinting at my KX3 and my K2 / external KPA100/EC2? > Anyone try it? > Frank KG9H > From n1al at sonic.net Mon Jul 27 20:49:43 2015 From: n1al at sonic.net (Alan) Date: Mon, 27 Jul 2015 17:49:43 -0700 Subject: [Elecraft] K3: 630m amplifiers In-Reply-To: <55B6CD97.9090005@socal.rr.com> References: <201507271744.t6RHhwG7021578@mail41c28.carrierzone.com> <55B67BB0.7040307@audiosystemsgroup.com> <55B69A4E.90400@sonic.net> <55B6CD97.9090005@socal.rr.com> Message-ID: <55B6D1A7.1090001@sonic.net> On 07/27/2015 05:32 PM, Phil Wheeler wrote: > Clearly you are not among those who reminisce about the rotary spark > gap, Alan :-) By crackey them vacuum tubes are just too durn delicate for serious ham radio work. Old reliable spark is much more rugged. Quoting from "The World of Ham Radio, 1901-1950, A Social History" by Richard A. Bartlett talking about the first issue of QST after World War I: In the two years that had elapsed since amateur radio was silenced, impressive progress had been made. Most significant was the development of the vacuum tube. At first known as audions, bulbs or lamps, the originals lacked uniformity, ... needed careful adjustments of the filaments and plate voltage, and were simply too delicate for "the Service." You could abuse a spark transmitter, but the tubes would die if you weren't gentle with them. Reminds me of comments I heard hams make about transistors during the tube-to-transistor transition 50 years ago.

I remember the CK722. I had one as an audio amp behind a crystal set I built using a 1N34, not sure it was even an A version. I had a 210 foot piece of wire strung from the radio, through my bedroom window to a post in the back of our yard. I could hear, almost all, the AM stations in the Washington, D.C. area, all at once. And, that was in the 1950's. The really nice thing about the set up is that a D cell battery could power the thing to drive high impedance headphones nicely. Coupling to the CK722 was directly to the base with no bias. It worked. It may not have been the best design, but it worked. For a young kid that was all that mattered. 73, Barry K3NDM On 7/27/2015 9:00 PM, Don Wilhelm wrote: > Those first point contact transistors such as the CK722 were rather > 'finicky'.

Never had an original K3, but the receive audio is good and filtering with the matched pair of 400s and the 250 in the main VFO was stunning during the IARU contest. I've only played a little bit on 6m and the preamp does a good job, I guess, but I'm not a big 6m guy to begin with. I have a very noisy amp (Ameritron AL-1200) that sounds like a jet engine. The K3S's noise gate makes phone operation so much better. I'm using an HC-5 boom mic element and without any TX audio EQ, MIC set to 35 (real panel, high) and compression of 12 to 15 I'm getting superb audio reports on-air.

Still integrating it into the shack. First contact was on 80 meters with the local HF net. Second was a ZL1 on the North Island on 40. Hard to compare it with other radios -- this replaces an Icom IC-7000, which isn't at all in the same league. Still learning how to run it. Still trying to figure out digital modes -- any places on the net to visit where I can find out what they sound like when properly tuned? Still waiting for third party software types to adapt their code to the new USB interface, particularly for those digital modes. Also waiting for another pair of filters to arrive. I wrote the (construction) review on eham.net -- and I sent off a slew of nits on the Rev A assembly manual, nothing major. Assembly was easy, only requiring three hands in a few places. Enabling options can be a challenge -- that could use a dedicated section with things gathered together in one place. As an example, I just figured out how to get the KXV3's second preamp for 10 and 6 working -- it's in the manual, scattered about a bit, but the magic step is to hit "9" on the keypad when the config menu shows KXV3 rather than KCV3B. Once that's set, the rest is easy. Wonderful radio -- never thought I'd own something of this calibre. My son KG6MOV surprised the hell out of me by getting this for me for father's day (he tried -- I told Mike at Elecraft that I was glad they had the problem of too many orders for the K3S, and hoped they had it for quite a while). It will be our Field Day radio next year. By then we'll be old friends and get along much better.

Point-contact transistors could be variable in terms of electrical characteristics, but mechanically they were a lot better than mythology presents. Regardless, the famous 1953 Raytheon CK722 was *not* a point-contact transistor. It was a Germanium junction transistor. It is very unlikely that anyone here ever worked with point-contact transistors...they disappeared quickly after the junction transistor appeared in 1951.

I don't recall that argument having much strength left by 1965. The Raytheon SBE-33 HF ham transceiver came out 52 years ago, followed by the SBE-34 two years later. They were all transistor except for driver and finals and were very successful ham rigs.

I guess the finals were direct-keyed and not driven by a keyed stage. Its been awhile. My DX-35 used grid-block keying and ran screen-grid AM on the 6146. But then you youngsters probably don't go that far back so would not know this. Just yanking your chain a little, Jim, so don't get all riled up by that statement (you and I both were licensed in the 50's; ex-K8MWA). I was thinking that my classic W6PO-8877 was running class-C but in fact is running linear (probably class-AB). Class-C was used in the past for higher efficiency when gain was expensive. Now even on microwaves gain is cheap. But you missed the point that I am not planning to build a class-C amp for 630m: "I think its just simpler to provide class-AB then its a non-issue"; a direct quote of what I said. If you look at my original post on this topic: "I am wondering what kind of interest there would be for a linear amp that could be driven by the K3s/K3?" No where did I suggest anyone use a class-C amp. Other's brought up using class-C, D, E. On 630m spectrum is dear so clean signals are more important than other bands. Likewise, frequency stability is also required to be a good citizen on the band. The ARRL Group specifies 1-Hz for both accuracy and stability. The K3 with TCXO-3 (1ppm) can do that. I don't have a P3. Guess I would have to use my old frumpy HP141T. 73, Ed - KL7UW Jim, nice pics on your QRZ.com ---------------------------------- On Mon,7/27/2015 10:43 AM, Edward R Cole wrote: > CW, JT65, FSK all do fine with class-C, of course.

The limit is the 32-bit arithmetic in the DSP firmware. 32 bits gives you 96 dB less some headroom to allow for the averaging function. I tried floating-point arithmetic but it increased the computation time by more than an order of magnitude. As you said, you can see the improved phase noise performance of the new synthesizer by simply cranking up the reference level and allowing the carrier to go off the top of the screen. Perhaps someone will do that when upgrading to the new synthesizer and post before and after plots. (Didn't somebody already do that?)

I should clarify that these are calculations that are done after the conversion from voltage to power, so you only get 3 dB/bit.

Of course, there are the usual used vs. new issues: * No warranty * Potential defects which have arisen in the used K3 Now if you work 6 meters or are very fussy about your RX audio, the K3S has pluses, though most (all?) of those can be addressed by upgrades which are (or will be) available to the K3. 73, Phil W7OX (I'm keeping my K3!)

My goal is DXCC/WAS then work DXCC for each band/mode. I aspire to primarily do CW but am currently re-learning the code with the goal to be armchair copy over 20wpm (we'll see how that goes). The opportunities I have are limited antennas currently and we may yet move in the next 1-5 years. Currently running a buckmaster 7 band OCF 300w version directed towards EU. The short term plan is to construct some better receiving antennas (vertical loop perhaps? Not enough room for proper beverages). Long term plan is a crankup/foldover tower with two or more elements on 40/20/15 as high as I can get it. At 50 my goal is to buy the last HF rig I'll need (hopefully). If I had a K3 and a K3S side by side with the same antenna, properly adjusted and tuned, could I hear a difference in signal quality, noise....etc.. ?

At 50, you are part of the youth crowd in this hobby. In 2004, I returned to ham radio after a 37 year absence since my Novice days in the mid 1960s. I was 57 years old in 2004. Since returning to the hobby 11 years ago, I have bought many rigs but my main at home station rig were: Icom 756 (non-pro) used, new Icom 756 Pro III, new Elecraft K3, new Elecraft KX3 (for portable work and as a backup rig). At 68, I am pretty sure that my current K3 is not my last rig ? I am still waiting for the K4 or maybe K5. 73, phil, K7PEH P.S. About CW and returning to the code ? when I returned to the hobby in 2004 I operated SSB only for 3 years. In 2007, I got interested in CW again. It had been 40 years since the last time I even heard a CW signal. If you had asked me for the CW code of the letter F or G or whatever, I probably couldn?t tell you. But, within a week?s time of listening to CW, I was copying again at about 13 to 15 wpm. My speed I obtained as a novice 40 years prior was about 20 wpm and I was the most surprised guy that it came back so quickly. Two weeks after the decision to get back to CW I made my first straight key CW contact. And, I flubbed it. I had not done any practice with the key on sending thinking that it was automatic and easy. Today, I am armchair at 20 wpm and during contests I can copy in the 30 to 35 wpm range (easy as contest exchanges are very easy to copy). My key of choice is my Begali Magnetic Classic Paddle. So, good luck on the CW ? it represents better than 95 percent of all my contacts these days. I haven?t called CQ in SSB for maybe 3 or 4 years. > On Jul 28, 2015, at 8:49 AM, ae4pb at carolinaheli.com wrote: > > Good points all around so far. > My goal is DXCC/WAS then work DXCC for each band/mode.

Especially after hearing about your goals, my recommendation is that you save yourself a lot of money and buy a late vintage K3, then upgrade to the K3SYNA board and the KIO3B board. The K3SYNA gets you improved RX and TX phase noise, and is 90% of the difference between a K3 and K3S. Cost is about $220, you install it in 15 minutes. The KIO3B gets you the latest preamp, which is a significant improvement on 10M and 6M. Spend your cost savings on a better antenna and/or adding a P3 or second RX. The differences between the K3 and K3S mostly matter when you're a serious contester, or if a neighbor ham living close to you is active when you are, or when you take your rig to Field Day. For the same reasons, I suggest that you avoid buying roofing filters until you've used the rig for a while. For your operating plans, you probably won't need them. I have a pair of early vintage K3s (2007) and I'm a serious contester. I did exactly those upgrades. 73, Jim K9YC From jkramer at iafrica.com Tue Jul 28 12:56:44 2015 From: jkramer at iafrica.com (John Kramer) Date: Tue, 28 Jul 2015 18:56:44 +0200 Subject: [Elecraft] Is there a good reason to buy a K3S instead of a used K3 ?

We (and I include myself in this) are too paranoid about every db or dBm that is reported in a test. I guess it?s the same as the power guys - trying to get every watt out of their radio - they complain that their rig is only putting out 95 watts, and they want to turn it up to 100 watts. To make a noticeable difference they would need at least 3 db or a doubling of power. I can?t remember if it was Eric or Wayne that said - getting your rig to the top of the Sherwood list is really only a great accomplishment for the engineers and designers, because all the rigs in the top 10 will hear equally well for the guys that actually use them on air. 73 John On 28 Jul 2015, at 6:10 PM, Phil Wheeler wrote: Re "If I had a K3 and a K3S side by side with the same antenna, properly adjusted and tuned, could I hear a difference in signal quality, noise....etc.. ?": Likely a question that Wayne, Eric or someone else at Elecraft alone can address.

If raw RF performance is what it's about or if you work 6m and find the sensitivity on the low side, then a K3S. But for most QSOs, you won't observe any difference, I suspect. I've just had a K3S here for the weekend to review (I edit Practical Wireless - sort of UK equivalent to CQ). I already own a fully-loaded K3 and have used K3 rigs to great success on several expeditions and in contests. What stood out for me as being a major improvement was the USB interface - so much easier to interface to the PC, run data modes, etc. Beyond that, the question is really, what is a K3 or what is a K3S? There are so many add-ons available (I, for example, need CW filters and a second rx) and a K3 can be upgraded with many of the new K3S boards that it needs a long hard think about where to spend your money. A fully-loaded K3 or K3S is NOT a cheap radio (but it's good).

Both Bob and I are retired from careers in pro audio and broadcasting. I've never had even the least dissatisfaction with audio from my K3s. I'm a contester and DXer, prefer CW but also do SSB contests to contribute to club efforts, and almost never do casual ragchewing. I mostly use headphones, either Sony MDR7506 or Yamaha CM500. I use the speaker for casual listening -- monitoring while I'm in the shack or running digital modes. 73, Jim K9YC From nq5t at tx.rr.com Tue Jul 28 14:20:19 2015 From: nq5t at tx.rr.com (Grant Youngman) Date: Tue, 28 Jul 2015 13:20:19 -0500 Subject: [Elecraft] Is there a good reason to buy a K3S instead of a used K3 ?

Unless your ham radio budget is unlimited (unlike most of us) take a look at what you're willing to spend and then balance it across the system. To belabor the obvious: a K3S with all the bells and whistles driving a legal limit amp into a dummy load might net you a contact across town. On the other hand, a K3/10 (or even a K2/10) into stacked monobanders or the LARAE (Line Array of Rotary Antennas in Echelon) from the ARRL Antenna Compendium would put you well on the way to DXCC etc. 73, Al On Tue July 28 2015 11:51:20 am Jim Brown wrote: > Especially after hearing about your goals, my recommendation is that you > save yourself a lot of money and buy a late vintage K3, then upgrade to > the K3SYNA board and the KIO3B board..... > > Spend your cost savings on a better antenna and/or adding a P3 or > second RX.

Probably not if the K3 had the new synthesizer installed. There might be a slight difference/improvement in overall speaker audio quality due to the updated audio amplifier but there is nothing "wrong" with the speaker amplifier in the K3. Even if the K3 had the old synthesizer, you will probably not notice a significant difference unless there is a very strong (S9+60 dB) relatively close when trying to work someone at the noise level. 73, ...

Message-ID: <201507282003.t6SK3DlN011276@mail40c28.carrierzone.com> (My opinion:) If buying a radio, I would buy the new K3S. If you already have a K3, then I would keep it and upgrade what you think is necessary for your use. One exception might be available cash. Probably you can save a little buying a K3 and upgrading it. I bought my K3/10 in 2010 (SN 4043) and have the KRX3 so will end up purchasing two Synth board upgrades. I operate on 600m but renewal of (ARRL Exp Group) license requires me to operate on 630m so I will obtain the kit to upgrade the K3 for operation lower in freq. I operate 6m, so I obtained a PR6-10 from a ham who upgraded to the new KXV3 which integrate the preamp inside the radio. I saved some and he got funds to put forward to his purchase.. win-win! Actually already had a 6m Gasfet preamp but it is being installed on the 6m tower for eme. The bypass feature of the PR6-10 works perfectly for switching between preamps and I get better 10m reception as a bonus. My station operates on 18-bands from 630m to 9cm, so its way too late to worry about too many external cables hanging off the radio. I have five transverters with assoc amps, three towers and a 16-foot dish; there are over 2-dozen coax running thru the wall entrance plate, and then all the control cables, etc. etc. In fact I just completed design of a new relay pc board for my station control panel rebuild (uses three boards with five DPDT relays on each board). 73, Ed - KL7UW http://www.kl7uw.com "Kits made by KL7UW" Dubus Mag business: dubususa at gmail.com From alsopb at nc.rr.com Tue Jul 28 16:07:04 2015 From: alsopb at nc.rr.com (briana) Date: Tue, 28 Jul 2015 16:07:04 -0400 Subject: [Elecraft] Is there a good reason to buy a K3S instead of a used K3 ?

Since people have yet to quantify what exactly is wrong with K3 auidio, it's going to be hard to quantify any difference. I fully expect some people to hear a "big positive difference" when in fact there may be none. It may sound different but characterizing it as "better" is going to be tough. Some might think it's worse. This is the problem with something which is so subjective. If this is your only reason for upgrading, perhaps you ought to hear before you buy. 73 de Brian/K3KO On 7/28/2015 1:57 PM, Bob McGraw - K4TAX wrote: > To me the audio enhancement for the K3S is expected to be a nice > improvement.

Message-ID: <55B81863.6000804@wi.rr.com> Hello, I need some help in choosing a monitor. I'm looking to buy a monitor to pair with my P3/SVGA combination. I'm more than slightly confused what to buy. The guy at my local computer store was less than helpful. He asked me twice what kind of video card I have in my computer :) In the SVGA manual it states::/ // //1024 X 768 //For faster screen updates when using fixed tune// //1280 X 1024 mode, we recommend setting the P3SVGA// //1440 X 900 resolution to 1440 x 900 or less. Note that 1920 X 1080 1440 x 900 will display correctly on 1920 x 1080 monitors. I want to get a nice big screen to take full advantages of the SVGA card. Several questions: 1) What is the best display type? TN (most common), IPS (what type?), MVA? Is the TN good enough or is there an advantage to buying an enhanced display? 2) What resolution should I buy? It seems that the most readily available is 1920 X 1080. Is there a problem with screen updates as stated in the manual? 3) The P3 display is square. What happens if I buy a wide screen monitor with a 16:9 format? 4) Do I need to worry about the refresh rate? 5) Do I have to worry about the contrast ratio or response time? 6) Is there any advantage to buying, say a 23 or 24 inch screen? Even a 19" screen is a big step up from the P3 screen so is going to a really big screen overkill? /7) If I add the P3TXMon option will that make any difference in monitor choice? 8) If I buy a monitor without a VGA input will one of the VGA to HDMI or DVI adapters work? /// I don't mind spending some money on the right display but don't want to buy something I don't need or won't see the advantages of.

I've used 1024x768 and been happy. A menu setting in the PS/SVGA lets you select from the scanning rates you listed. The SVGA module does its own FFT based on the horizontal resolution of the selected display. For about a year, Costco has been selling a very nice 23-in LCD Samsung monitor that has the added advantage of running from 12V. That means you can cut the power cable, install a power pole, and toss out the switching power supply. I've replaced four older monitors with these. They draw about 1A. Max resolution is 1920 x 1080. Specs are not critical for use with the P3/SVGA, and it adapts to 16/9 just fine. 73, Jim K9YC On Tue,7/28/2015 5:03 PM, Gary K9GS wrote: > Hello, > > I need some help in choosing a monitor.

In-Reply-To: <55B81863.6000804@wi.rr.com> References: <55B81863.6000804@wi.rr.com> Message-ID: Hi Gary, Here's a different approach to the display issue. I really don't have the space for a separate monitor to go with my P3's SVGA option. But I do have a 30 inch HP LP3065 2560x1600 monster monitor in use on my PC. And what I really wanted was to have the maxi-definition SVGA from P3 up on the main monitor in a window. What I did was to get a StarTech Video Capture card for my PC. Then connect a VGA monitor extension cable from the P3 to the capture card. The software that came with the card has three modes, opening miniscreen (plus menus for a bunch of stuff regarding recording the screen), full screen, and naked video window at incoming resolution. I use the last for viewing the P3 SVGA output. When I set the window of 1280 pixel width source to half the 2560 monitor pixel width, I get a stunning clear, sharp focused representation of what is going on. If I get real close to the screen I can see that some of the band noise information in the waterfall is single pixel. Also the spectrum display lines, if you hit freeze, are a single pixel in width. Very sharp. The display of clicky CW signals on a narrow span shows a lot of stuff that is highly individual. You can literally see the baud rate sidebands. The model of the StarTech video capture card I used is PEXHDCAP. The guts of the card has the whatever to capture full HD off an HDMI input (as long as it's not copy protected). Will take DVI input, or component RCA. SVGA is via supplied VGA to DVI adapter, which I am using. Got card off Amazon. The drivers on the CD that comes with it are cr*p and dangerous. For this card one needs to get the most recent drivers and the Stream Catcher program off their website. A very interesting thing, none of the Stream Catcher windows can be dragged from the edges like a normal window. You have to click and drag with the cursor in the video material, which really had me going and was only solved by a text chat session with their tech support. Good luck all. 73, Guy K2AV On Tue, Jul 28, 2015 at 8:03 PM, Gary K9GS wrote: > Hello, > > I need some help in choosing a monitor. I'm looking to buy a monitor to > pair with my P3/SVGA combination.

I agree that DB9 is an incorrect designation, but many professionals use it, even some famous ones, .. e. g. Elecraft ! In my KPA100 and KAT100 manuals, the DB9 designation is used in the parts list. I also agree with Jim, K9YC about the docking station : my laptop is dedicated to the portable traffic and my wife thinks that the K2/100 + KAT100 +PSU + Mike +Headset + portable Antenna + Laptop +.. is already too much for the trunk, specially if we have some grandchildren with us ! Before to put the "Hands on", I will spent more time in checking the various vendors suggestions I received through the Reflector. Have a good day and 73 ! Ray, F4FNT P.S. Since I receive the Reflector via the daily Digest, I didn't receive all the answers on same day.

It really seems to boil down to convenience, and maybe a little difference in money. Elecraft has NOT made the K3 obsolete. The K3S, for the most part, is just a repackaged K3. There is an advantage to the K3S, however, in that many of the items that are add-ons to the K3, are now built into the K3S. Some of those features may not even be important to you, and if not, why spend the extra money? Still, an all inclusive package will be very appealing to many which is perfectly understandable. In essence, you have even more choices!!! Significantly better performance, however, is not obtainable by buying a K3S as long as you upgrade your K3 appropriately. I have a fairly early serial number K3. Over time I have added the various upgrades and accessories. I recently acquired the new syn boards, and probably will upgrade the DSP when that becomes available. From everything I've read there is apt to be no significant improvement that a K3S would give me over my older K3. If I want, I can even add the USB option to my K3. So, what little difference is out there between my upgraded K3 and a new K3S, actually boils down to a significant cost differential, and for very little noticeable difference. My K3 is performing very well, and I know of no reason why that will change anytime soon. It gets very hard to justify that unless money is no object. I have to say, though, that I do like the idea of not having my 6 meter pre-amp hanging off the back of the radio! Maybe a K3S is in my future too, but right now it doesn't seem to make much sense. A lot depends, I suppose, on what happens to pricing for used K3's. You definitely would want the new syn boards, so the price for a used K3 without them should reflect that absence accordingly. It does make shopping for a used K3 a bit more complicated. That fact alone may cause you to go the K3S route so you don't have to worry about it. However, if you already have a K3, and are just considering upgrading models, I'd probably recommend against it. That's the "trap" that other manufacturers get you into, but not Elecraft. The TS-590 may be a good example. The new "SG" model is significantly improved. I think there was some sort of upgrade process for older models, but I don't think it went all the way to "SG" equivalency--not in the way a K3 can be upgraded to nearly identical specs to the K3S. Anyway, if that is not a good example, there are plenty of others that do make this point. In short, it would be pretty hard to make a bad decision, either way. The biggest difference between the two choices is apt to be "money", but if it buys you the convenience you really want, then probably it is worth it. For that matter, the cost differential, spread over the life of the radio, becomes pretty insignificant. Probably not enough to get a brain cramp over!

I agree completely that the K3S is an upgrade to the K3, and an existing K3 can be upgraded to almost the equal of the K3S - the RF board cannot be upgraded, but just about all the other changes can be incorporated into your K3 should that be desirable. I consider this upgrade to be similar to what happened to the K2 at serial number 3000. The boards were redesigned, and all the prior upgrades were incorporated into the new boards. The older A level boards could be upgraded with the kits provided by Elecraft, and there were only a few minor differences between an upgraded A level K2 and the newer B level. I believe Elecraft is unique in allowing customers to upgrade to the latest level by providing upgrade kits at a modest price. 73, Don W3FPR On 7/29/2015 5:51 AM, dyarnes wrote: > That's the "trap" that other manufacturers get you into, but not > Elecraft.

Please refer to the P3/SVGA Manual Rev E and the P3TXmon Installation Guide for more information. Note: if you are upgrading your SVGA to the new 1.24 beta, you do not have to download the fpga files as they have not changed. The release notes for these revisions: MCU 01.50 / 7-27-2015 * Added support for the transmitter monitor module. Added a new "TXMonMenu" sub-menu with entries: "CW Split" (enable split screen for CW mode), "Mtr En" (turn on the "analog" meter display), "MtrScale" (set power meter full scale), "Mod En" (turn on the modulation envelope display), "ModScale" (set time/div of modulation display), "SensorCal" (RF power calibration, separate for each sensor type) and "TX hang" (delay time when the transceiver goes from transmit to receive). * Added an additional middle-sized font selection of 7 x 11 pixels. * The waterfall parameters for the external display are now different from the main display. The following new entries have been added to the "SVGA menu" sub-menu: "SVGA WfEn" (turns the waterfall on/off or sets it to track the main display), "SVGA WfAv" (waterfall averaging on/off), "SVGA WfCo" (waterfall color map), "SVGA WfHt" (waterfall height), and "SVGA WfMk" (waterfall markers on/off). * Supports preamplifier number 2 of the KXV3B (which is standard in the K3S). P3SVGA 01.24 / 7-27-2015 * Added Noise Blanker. * Developed a faster method of detecting K3 transmit/receive state changes. * Added data terminal ?send on space? to the available data TX modes. * Added replay of keyboard input using Ctrl-Alt-R. Ctrl-C will clear replay buffer. * Added ?\r? to embed a CR in text message. Use ?\\? to send a single ?\?. * Added ?\c? to embed an incrementing serial counter in a text message. Clearing/presetting counter may be done in the setup screen (Ctrl-Alt-S). * Text messages sent in data terminal mode now respect the mode setting (VOX, CR, ^T). * Fixed a bug in data terminal mode that was causing the time-out to not reset correctly. * Fixed a bug in data terminal mode that was causing non-existent characters to be retrieved and sent. Also fixes a bug of missing characters. * Fixed a problem that caused some SVGA boards to not initialize correctly from P3 commands at boot. * Added waterfall cursors, these display exactly as they do on the P3 screen. 73, Paul N6HZ -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-SVGA-Beta-1-50-1-24-now-available-P3TXMON-tp7605498.html Sent from the Elecraft mailing list archive at Nabble.com.

For a particular transceiver one have to refer to the pinouts shown on the next pages of the ACOM 2000A manual. For K3 a male DB9 connector have to be used on the place of the female connector shown on the generic "Y" cable picture. That mirrors the pins as you can see on the K3 cable diagram (Fig. 7-6).

Message-ID: <4ABA548D-BFEB-4339-9C7D-E7AFC06F7E8A@yahoo.co.uk> Experimenting with the KX3 on WSJT FSK441 and JT65b I noticed looking at the spectral display of band noise that with the bandwidth widened fully out on DATA A Mode that even though it was displaying 4 KHz on the KX3 LCD, the bandwidth of the audio was less, like 400 Hz to 3600 Hz. On SSB mode it was possible to get the full 4 KHz by suitable manipulation of the width and centre frequency. It is useful on JT65 on EME if you are running a pileup from a rare DXCC to have stations spread out and having the full 4 KHz is beneficial then. Under normal circumstances not at all important, but I was just curious why DATA A mode is not giving the full 4 KHz while the SSB mode is. If I am missing some setting that is causing this please enlighten me. (I prefer using DATA A to the SSB Mode on WSJT as it does things like turn off TX equalisation and compression and other things like NR on RX which might upset WSJT). 73 David Anderson GM4JJJ From brian.waterworth at gmail.com Wed Jul 29 18:10:11 2015 From: brian.waterworth at gmail.com (Brian Waterworth) Date: Wed, 29 Jul 2015 18:10:11 -0400 Subject: [Elecraft] SideKar vs PX3 In-Reply-To: <55B8C804.1050002@gmail.com> References: <55B8C804.1050002@gmail.com> Message-ID: Warning - long response One thing I have found on my quest to have a portable station is a portable computer, screen, and keyboard. My premise is that the kx3 may not be ready for a complete psk31 solution with either the px3 or the sidekar. I'll come back to this quest in a moment. At present, it doesn't seem that the kx3 applies afc to incoming digital transmissions, like psk31. Keeping a frequency lock on psk31 signals tends to require multiple presses of the cwt button during a qso to instruct the kx3 to re-tune to a psk31 signal. You will miss portions of the transmission because of this. I don't believe this variance can be corrected by the kx3 as these variances may be at the other ham's transmission end or due to atmospheric conditions. I believe that to really get the most out of psk31, you need afc at the receiver end. The kx3 doesn't have it. My premise is that unless the kx3 has afc, using the internal psk decoder is for emergency purposes and having some fun. More frequent amd fulfilling psk operations will, at this time, need to be with an external program. I am open to other view points, but I find the kx3 and any associated programs that help you access the onboard digital features lacks afc, usability, and agility one needs when operating psk31. I tried various programs to reach the nirvana I enjoy on my main shack computer and other digital programs (e.g., fldigi, dm780). I found an application that is OK, but the program needs usability enhancements and it seems the author has gone quiet on new features and improvements. The program is PSKer on an iPad. It has the afc feature. This helps greatly. It has macros, but even these as not as flexible as programs like fldigi. If you are used to selecting the call sign of a potential qso from the receive decode window, you won't be able to do it. Search and pounce is much harder to do when you have to take the time to remember a call sign and type it into another field while the receive window is scrolling. Fldigi and dm780 will allow a quick click of the mouse and the call sign is ready to be used in any macro that references this field. Now let's turn to the question about the USB port on the px3 and the connection of a keyboard. I contend that unless the kx3 adds more psk features like those of the mainstream programs found on various platforms, the addition of a keyboard for psk qso's as decoded by the kx3 may not be useful. I actually don't like my premise as I was excited too about the possibility of a keyboard attached to thw px3. But what would I use it for? The aforementioned usability concerns and lack of afc in the kx3 doesn't provide me with the utility I thought I was going to get from the kx3/px3 combo. If there is another use for a keyboard that I have missed, I would love to hear it. My first setup I use for psk is psker, iPad air, apple Bluetooth keyboard and I connect the kx3 to the iPad using an apple camera adapter (essentially a lightning based usb port) and a griffin iMic. Actually any USB sound card will likely be OK for psk. Why a Bluetooth keyboard? The iPad keyboard obscures almost half of the screen. Not very good when you are trying to remember a call sign to type into a field that you can't even see when the pop up keyboard displays. Consequently, an external keyboard is essential. Tablet Application developers for our ham apps are not creating apps that are usable on tablets when the onscreen keyboard pops up. By the way, PSKer can only do psk31. The second computer setup I am working on is a little more work, but I am hopeful will be more usable with the programs I love to use (fldigi). It is a raspberry pi2, wireless adapter for the pi, iPad air, apple bluetooth keyboard and kx3. The difference is that I use the iPad as a screen for the pi via vnc. I use the ipad touch screen as the mouse. I connect the ipad to the pi using an ad hoc wireless connection. I connect the griffin imic to the pi instead of the ipad. The pi operates on just over an amp hour and can run off of a mophie spare battery pack for a few hours. I am working up to more serious portable power in the future and recent conversations on this reflector have been very helpful. With this setup, I have access to many more digital modes and afc. I can also use my macros from the main shack computer for field day or contest operations. My initial work has met with success and so far this second portable computer setup is much more usable. But, a challenge is that you will need to know about Linux and setting up wireless networks. Not the easiest thing on the pi, but with Google and a little patience, it is possible. I think even the sidekar may not meet your digital needs. I am sure the sidekar does more and my apologies to the designers if I have under represented it's capabilites. I saw the sidekar at Dayton in 2014 and wondered why I would need it over a px3, especially with the px3 firmware upgrade that provided two lines of decode text on the px3 screen. The sidekar is not a general purpose computer and therefore is limited in its usability. How would you capture a call sign from the receive window to respond to a cq? Where would you store this call sign in either the kx3 or the sidekar? Usability and adaptability during digital qsos is necessary in order to keep up with those hams that are working in a much more productive environment. I am sure there are others who have different setups and experiences to mine. I am interested to hear about them as is Steve.

His instruction to set the "microphone" level to 100% is completely *wrong*. Right click on the microphone slider and set the display for *dB*. In Windows 7 the microphone slider scale will range from -196.0 dB at 0 to +30 dB at 100% while in Windows 8.1 the scale will be -96.0 dB to +30.0 dB. Negative gain levels represent attenuation in the CODEC while positive gain levels represent excess gain. Sands is completely *wrong* when he says any value below 100% represents attenuation. In fact *any* "dB" value above 0.0 represents *GAIN* in the CODEC. The best recommendation for setting USB levels for any "microphone" input supported by the Windows "USB Audio Class" driver is: - go to Control Panel | Sound | Recording tab, double click on Microphone - USB Audio Codec device - on the Levels tab, right click on the microphone slider and set the units to *dB* - adjust the slider for 0.0 dB +/- 0.5 dB - this will typically be 3% in Windows 7 and 54% in Windows 8.1 - tune to strong carrier (S9+) - watch VU meter on Recording tab and adjust output level from the radio (typically the RX pot on the interface - "Line Out" in the K3/K3S) to 2 bars below full scale. If it not possible to reach 2 bars below full scale (the K3/K3S has plenty of excess drive) increase the level slider slightly until signal is no more than 2 bars below full scale. I no longer have working XP or Vista systems and do not recommend the use of obsolete operating systems. However, the same procedure (adjust for 0.0 +/- 0.5 dB) should also work with XP and Vista to prevent overdrive and clipping there. In any operating system, a 0 dB input gain setting will provide the best balance of dynamic range and sensitivity in a sound card with properly designed audio input circuits.

Without "clearing" the bug forcing windows to enumerate it as a line in device, 100 on the slider is indeed adding gain. However after clearing the bug, it's now enumerated as a line in device and 100 on the slider is 0db, even if it reads +30 (the UI and dialogue box still thinks this is a microphone input device, this is part of the bug). This was verified by feeding a reference signal of a known level into the chip and obtaining a known output level, confirming 100 on the slider is indeed 0db of gain/attenuation AFTER clearing the bug. This behaviour is confirmed by TI themselves in this whitepaper: http://www.ti.com/lit/an/sbfa020/sbfa020.pdf If you have a signal generator I highly recommend feeding a reference level signal into a device using the chip and measuring the output yourself AFTER clearing the bug. Remember, you are correct that the slider value will add gain when it's been incorrectly enumerated as a microphone device. Measure a reference input signal AFTER clearing it. Hope that helps the confusion 73 TJ W0EA From gm3sek at ifwtech.co.uk Thu Jul 30 04:13:25 2015 From: gm3sek at ifwtech.co.uk (Ian White) Date: Thu, 30 Jul 2015 09:13:25 +0100 Subject: [Elecraft] [KX3] DATA A v SSB maximum receiver bandwidth not as wide.

Whenever you select DATA, the stored SHIFT and WIDTH settings will always be the last settings that were used for *any* data sub-mode on *any* other band... which may often be quite inappropriate. This is a particular inconvenience for all users who switch frequently between narrowband data modes on HF and wider-band modes on 6m and above. (It obviously isn't a major problem; I only mention it in case Elecraft might be revisiting this area of code.) 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >David Anderson >Sent: 29 July 2015 22:28 >To: Elecraft Reflector >Subject: [Elecraft] [KX3] DATA A v SSB maximum receiver bandwidth not as >wide. > >Experimenting with the KX3 on WSJT FSK441 and JT65b I noticed looking at >the spectral display of band noise that with the bandwidth widened fully >out on DATA A Mode that even though it was displaying 4 KHz on the KX3 >LCD, the bandwidth of the audio was less, like 400 Hz to 3600 Hz. > >On SSB mode it was possible to get the full 4 KHz by suitable manipulation >of the width and centre frequency. > >It is useful on JT65 on EME if you are running a pileup from a rare DXCC to >have stations spread out and having the full 4 KHz is beneficial then.

In particular, when software is not executing correctly you should remember that it is not doing what it is supposed to do. He does not ask you to "set the microphone level to 100%" ? he says to adjust the erroneous interface control to the 100% position. Not the same thing. Watch the video (and pay attention to the oscilloscope displays), then try it for yourself to see what happens. I hope this helps ?

I do use fldigi. Yes, PSK31 is difficult to tune and partly because of the lack of AFC in the kX3, as you reminded me (why... KX3 tuning is difficult). The PX3 does make it easier to tune provided the sending station isn't drifting. RTTY seems easier to tune - I guess because of its wider bandwidth. I think because I want portable PSK31/RTTY to be fun (not frustrating), I need to think about using Fldigi portable with a small/mini laptop (solid state "disk"). I guess I will also think more about how I am going to "do" the little bit of CW as the decoder works well (not great). I am going to give CW via KX3 decoder a try this weekend with the NAQP. Yes, I think even with the HCT/SideKar you need to save the call. It does have a memory location to allow the call to be sent as part of a macro. I don't see anything in the manual about logging using the memory location to fill the log callsign... I'll ask/look. thank you for your thought provoking input. 73, steve WB3LGC On 29-Jul-15 6:10 PM, Brian Waterworth wrote: > Warning - long response > > One thing I have found on my quest to have a portable station is a portable > computer, screen, and keyboard.

Any time someone says to run the "microphone" level of a PCM29xx series USB CODEC at 100%, he obviously does not know what he is talking about. 100% represents 30 dB of gain (appropriate for a microphone) - about a 30 x increase in voltage between the codec input and ADC - which will most certainly cause clipping. The Microsoft supplied drivers for Windows 7 (and presumably Windows XP/Vista) do not make setting the CODEC gain easy as they are *all gain* from 3% to 100% but it can be done. The drivers for Windows 8/8.1 have been fixed in that the microphone setting is gain above about 50% and attenuation below that. *THERE IS NO PROBLEM IN WINDOWS 8/8.1*. In any Windows version the easy solution is to *right click* on the microphone slider, set the units to display in dB, and set the level to 0 dB +/- 1 dB. In addition to the difficulty in setting levels in Windows 7 and before, there is a bug in the USB Audio Class driver with regard to any USB Audio device that reports *one* microphone input - Windows will reset the level to maximum gain each time that endpoint (input) is opened. Resetting the input level to 100% is the only "bug" here and that has been fixed in Windows 8/8.1 (presumably Windows 10 but I have not updated any of my systems to confirm the repair is present). 73, ...

A while back I picked up a used Toshiba NB-205 (10" screen, 1.6G Atom processor, 1G RAM, 160G HD, XP Home, extended run battery) for a lot less than a new netbook would cost. Since MS no longer supports XP I reloaded it with Debian Linux. It runs very well with a lightweight desktop environment like LXDE or XFCE and can be configured to look/feel very much like XP or Win 7. (I also have Linux installed on my XYL's desktop system, and she flips back and forth between it and her Windows system at work with very few problems. Note that by her own admission she's not particularly "tech savvy.") FLDIGI is in the Debian 8.1 repository and is also available for Ubuntu and other Linux distributions. Here's the beauty of it: if you want to try FLDIGI under Linux, download the install image, put it on a USB stick per the instructions, and set it up on your system. If you have enough disk space re-size the Windows partition and go dual boot. Then, if you don't like Linux, remove the Linux installation: all you're out is your time and effort. 73, Al On Thu July 30 2015 7:34:15 am brian wrote: > It seems this dilemma can be solved by something like a 10" screen > WINDOWs laptop.

He says that any setting of the mic slider other than 100% is attenuation. That is completely incorrect as can be demonstrated simply by setting the legend to decibels instead of percent.

I do use an SDR-IQ running SpectraVue on my K3 and have a second one to use with my new K3S when it gets back from Elecraft rehab:-( To me the P3 display is just too small. Apparently, many agree, hence the VGA adapter. So if you get a P3 you might decide you need a bigger monitor, which puts you back in your dilemma. Why not just add the second monitor to your setup now. All of my software runs on a laptop with a 22-inch external monitor. When I get my station rearranged, I plan to run two big monitors.

Buying a K3S has been tempting in the way that buying the latest model car sometimes is - though I should disclose that one of my cars is 14 years old and well into its second 100,000 miles. But as a practical matter, with the K3 upgrades (which I am doing), that temptation hasn?t moved me to buy the new model. One improvement that would make me jump to a new model, almost regardless of the cost, probably won?t be available until the K8 or K9, namely a Blue Tooth-type system for ridding my desk of the cabling jungle connecting the K3 to the KPA500, the KAT500, the P3, the PR6-10 (yes, I know that one is in the K3S) and all the rest. OK, I?d allow two to remain - DC in and RF out. As for the related question, of someone who has no K3 buying a used K3 versus a new K3S, two variables would be important to me. One would be cost. The other would be quality. I would rather buy a K3S kit than a used K3 even if factory-built, to have the advantage of knowing my radio more intimately by building it. That difference would be worth a goodly amount of difference in the price. In addition, buying a used anything is always a trip into the unknown, with no guarantees and the risk of problems, disagreements, and all of that. Avoiding that sort of risk is also worth a substantial amount of money. The analysis of that question is different from that of the question of upgrading an existing K3 versus buying a K3S: While I plan to keep my 100,000+ mile car indefinitely rather than trade it in on a new one, only someone truly desperate should want to buy the old one from me, regardless of the lower price. (But I am open to offers - it?s a cream puff 2001 Infiniti QX4 as is / where is - replies off-line, please.)

No, enumerating the device as a microphone input is *not a bug* when the device descriptor specifically identifies the input as microphone. If the designer is using the PCM290x device in a "line in" deign, he should be using the PCM290xC (or current equivalent) which identifies the input terminal as 0x603 (Line connector) instead of the PCM290xB which identifies as microphone. 73, ...

Building a K3 is really a mindless process of bolting together subassemblies following a very well designed checklist. A few months later, all of the individual steps get erased from active memory, and when the time comes for disassembly to perform a mod or repair, I have to dig out a checklist for how to disassemble the radio. About the only thing I remember is how to take off and reinstall the top cover. For example, when I recently smoked Diode D5 on the KXV3, I had to dig out a procedure for installing the RXA Board on the KXV3 to tell me how to gain access to the KXV3. It's not like I remembered how to take the radio all apart. On the other hand, I can say, "OK, I built this %$#@, so I guess I can follow a checklist to take it apart and fix it." Doing the mods on an older radio, and fixing failed items have actually been more beneficial to me than the initial build, because I have become more confident, and purchased more tools to handle SMD's. By the way, here's the best $8 tool I have found for working with SMD's: http://www.amazon.com/SE-MH1047L-Illuminated-Multi-Power-Magnifier/dp/B003UCODIA/ref=sr_1_1?ie=UTF8&qid=1438269064&sr=8-1&keywords=headband+magnifier Dave Hachadorian, K6LL Yuma, AZ .

During 6M E-skip season, my K3 is usually monitoring either 50.125 or 50.276 in the main RX, with the sub-RX in the CW band, and the P3 displaying 50.080 to 50.280. With this setup, I'll quickly see any band activity. The 50.276 RX will feed WSJT-X. Once short-sequence ISCAT-B gains more traction, I'll monitor 50.248, the ISCAT-B calling frequency. On HF, I use the Sub-RX for Diversity reception, and to listen on my TX frequency when I'm running split. 73, Jim K9YC On Thu,7/30/2015 9:27 AM, Ken G Kopp wrote: > It's likely not a common usage, but mine's parked on 6M with a dedicated 6M > antenna listening for openings. > > 73 > > Ken - K0PP > On Jul 30, 2015 10:10 AM, "David Ahrendts" wrote: > >> >How would you use the K3S Sub Receiver?

Also agree that the details of construction disappear from memory. What has stayed with me, however, is an overview appreciation of the gross mechanical architecture (plus very detailed memories of the pain of installing the sub receiver) and, since I tried to avoid making it mindless assembly, an appreciation of how stuff fits and works together. The difference in price between buying a kit and buying a factory built is trivial; that has never been why I?ve bought a kit. And the advantage of buying a factory built is the much higher probability that what you get will actually work as it?s supposed to. Nonetheless, I bought everything I own as a kit, and would again.

Please email me directly *if* you have an immediate need for one of the changes described below, and can do testing right away on either a K3 or K3S. Thanks, Wayne N6KR * * * MCU 5.32 / DSP 2.83 / FPF 1.23, 7-28-2015 * DIVERSITY WORKS WITH MISMATCHED MAIN/SUB RX FILTERS: Diversity mode in the K3S (or a K3 with the KSYN3A installed) now works with any combination of main/sub RX crystal filters. They can have different bandwidths or offsets, and an equal number of filters in each receiver is not required. Note: Matched filters are optimal for diversity, but non-matched filters will still perform well. * "SAFE" OPTION FOR PTT/KEY USE WITH THE USB PORT: PC applications can activate PTT and KEY at the K3S via the USB port's RTS/DTR signals. However, initial setup of the rig's USB port by the PC may cause pulsed or continuous activation of the transmitter. This can happen if the computer is turned on after the K3S, or if the USB cable is not connected. "Safe" mode disables PTT-KEY transmit until the K3S receives a command via USB, such as a read of the rig's VFO frequency. To turn on safe mode, go into CONFIG:PTT-KEY and tap '1' to select "USB.SAFE". Exit the menu and turn the K3S off/on. Applications that use PTT-KEY but don't send commands will require "UNSAFE" mode (the default). In this case, be sure to turn the PC on before the K3S. * OVERRIDE OF UNEXPECTED PTT-KEY TRANSMIT: You can now override transmit due to a persistent PTT or KEY signal applied by a PC. (See PTT-KEY via USB, above.) If the K3S goes into TX mode unexpectedly, tap the XMIT switch. This will exit transmit and show ERR KEY or ERR PTT on VFO B. Once the PTT or KEY source as been removed, transmit will be re-enabled. If the cause may be unneeded PTT-KEY activation via the USB port, go into the CONFIG:PTT-KEY menu entry and set the parameter to OFF-OFF, or go into CONFIG:RS232 and set the parameter to anything other than USB. The menu can now be used during transmit in all cases. For Application Developers (also see Programmer's Reference, rev. F2): * PARAMETER ADJUSTMENT VIA "UP" and "DN" COMMANDS: UP and DN now apply to all settings adjusted using VFO A/B, including: NB, NR, manual notch, pitch, and text decode . (It also still applies to the menu.) It does NOT apply to special displays controlled by VFO B (use DB), or to settings controlled by the small encoders. * OM (OPTION MODULE) COMMAND CHANGES: Three new single-letter fields have been added to the OM command: 'L' (low-noise amp/preamp2 available on present band), 'V' (KSYN3A installed, allowing the VFO to tune down to 100 kHz), and 'R' (K3S RF board in use; see impact on RA command, below). Note that 'L' (preamp 2) only applies on 12/10/6 meters. Preamp 2 is located on the new KXV3B module. * RA (ATTENUATOR) COMMAND FORMAT CHANGE: If a K3S RF board is in use (determined using the OM command, above), the set/response format of the RA command uses dB values (RA00/05/10/15). The K3 format is still RA00/01. Note: 5 and 15 dB attenuator settings only apply to the main RX. The sub RX attenuator is 10 dB, even in the K3S. But if a K3S RF board is detected, the sub RX RA format is RA00/10.

If you do, it has to stop averaging when the freq is being changed while tuning, temporarily raising the noise floor slightly. It then re-starts multi-pass averaging once you stop tuning. This is normal for signal averaging. I run with averaging set =2 or 3 passes. When I tune I barely notice a small increase in the noise floor. If you have a lot of local pulse noise, you might want to turn on the P3s NB function to help. If Averaging is turned off, I can't think of a normal scenario where the noise floor would go up when tuning the band. It certainly does not here.

You need to turn on Fixed Tune Mode -- that's one of the functions you want to assign to one of the F-Keys. That prevents the P3 from re-centering every time you tune, and causes it to work like you want. 73, Jim K9YC From dmb at lightstream.net Thu Jul 30 17:31:30 2015 From: dmb at lightstream.net (dmb at lightstream.net) Date: Thu, 30 Jul 2015 17:31:30 -0400 (EDT) Subject: [Elecraft] P3 vs SDR-IQ In-Reply-To: References: Message-ID: <64328.71.74.118.201.1438291890.squirrel@mail.expedient.net> Joe, Are you by some chance using your P3 with the "FixTrack" mode set to "Tracking mode" rather than "Fixed-tune mode"? If so, WHY??? ;-) I used PowerSDR with a FLEX-5000A for years and always hated that it ONLY supported what Elecraft refers to as "Tracking" mode. Eventually, as PowerSDR was completely reworked for HPSDR (and now ANAN) the "Fixed-tune mode" was implemented and works well though it has a couple of minor bugs. The new FLEX 6000 series SmartSDR uses "Fixed-tune mode" as well. I don't know if it's even possible to get it to work in tracking mode -- I've never tried, and have no idea why one would want it to. Regarding the P3, I've been using the P3/P3SVGA with my K3 daily for about 3 1/2 years now in Fixed-tune mode, and have *never* seen any change in the noise floor during tuning under any circumstances regardless of the level of averaging used. If you are seeing the noise floor change in any way while tuning in "Fixed-tune" mode, then something is definitely wrong. Best of luck in getting this resolved. 73, Dale WA8SRA > I have been using a P3 with my K3 for the last two weeks and not happy > with it's > operation.

Here's my observations: My radio is the K3S (built last Saturday). The mismatched filters were robbed from my old K3 (s/n 398) along with the sub Rx and transplanted into the new K3S. The "old" radio also has the new Synth boards. In that previous radio I ran diversity without the 200 Hz filter enabled in the sub receiver, using instead the stock 2.7 KHz filter which had an offset nearly identical to my main Rx 200 Hz filter.. My 200 Hz filters were not matched, having been ordered separately at different times. One is -.91 and the other is -.72 offset. In the past I had tried to set a compromise of about -.80 on both filters for reasonable diversity but then they were so poorly aligned that sensitivity and passbands suffered from being on the steep slopes of the filters. 200 Hz. filters just don't allow much latitude to compromise the offsets. Now with FW 5.32 I'm listening through both filters at 150 Hz bandwidth in diversity mode with the filter offsets at their prescribed amounts. I'm currently listening on 30 meters. I'm hearing weaker signals gently passing between my ears very slowly with no particular rhythm and with no woosh-woosh. Those of you using diversity will know what I mean. It's great! My antennas are a 1/4 wave sloper on the main and a Pixel loop antenna on the AUX input to the sub receiver. I now don't see a real need to have the 5 pole filters matched to achieve great diversity reception. This setup is sounding great! I LOVE IT! Without diversity reception I would not have 160 Meter DXCC from my small, noisy city lot. Now it's just gotten better. Great job, Wayne and guys and gals!

For reference here it is again. Experimenting with the KX3 on WSJT FSK441 and JT65b I noticed looking at the spectral display of band noise that with the bandwidth widened fully out on DATA A Mode that even though it was displaying 4 KHz on the KX3 LCD, the bandwidth of the audio was less, like 400 Hz to 3600 Hz. On SSB mode it was possible to get the full 4 KHz by suitable manipulation of the width and centre frequency. It is useful on JT65 on EME if you are running a pileup from a rare DXCC to have stations spread out and having the full 4 KHz is beneficial then. Under normal circumstances not at all important, but I was just curious why DATA A mode is not giving the full 4 KHz while the SSB mode is. If I am missing some setting that is causing this please enlighten me. (I prefer using DATA A to the SSB Mode on WSJT as it does things like turn off TX equalisation and compression and other things like NR on RX which might upset WSJT). 73 David Anderson GM4JJJ > On 30 Jul 2015, at 23:24, Wayne Burdick wrote: > > I thought we'd hit the statute of limitations on this one.

When he refers to ?noise floor? he means that he loses averaging when he tunes, resulting in the crazy spectrum display (what Joe refers to as noise). I haven?t seen or used a P3, but I bought my first Elecraft products 3 weeks ago - a KX3 and PX3. If the P3 behaves in the same manner as the PX3 then I can see what Joe is complaining about. Right out the box my PX3 had this frustrating feature of losing averaging the moment you spun the VFO on the KX3. I pointed this out to a local KX3/PX3 owner, and he told me to download the latest firmware which allows you to select ?fixed mode? or ?fixed track?. I downloaded the firmware. YES, it kinda fixes the problem?.you can now tune the radio and KEEP the averaging?.but the problem is that now your receive filter goes down the display as you tune. This is better than the previous method, however you now have your receive filter heavily offset from the centre of the display. You might tune down the band, with your RX filter at the bottom of the scale, and you are now unable to see much below, but you can see a huge chunk of the band above you. I bought the KX3 and PX3 for portable ops. My main rigs for the past 5 years are Flex rigs. I have the 5000/3000/1500 and will be getting a 6500 soon as my shack rigs. With these rigs and PSDR, your RX filter REMAINS CENTRED and when you tune around the band, you DON?T LOSE your averaging. This is how I like it to be, and if Elecraft can achieve this in a firmware update, I would be very happy. 73 John, ZS5J On 31 Jul 2015, at 2:56 AM, Eric Swartz - WA6HHQ, Elecraft wrote: Hi Joe - Do you have signal averaging turned on to reduce the noise floor? If you do, it has to stop averaging when the freq is being changed while tuning, temporarily raising the noise floor slightly. It then re-starts multi-pass averaging once you stop tuning. This is normal for signal averaging. I run with averaging set =2 or 3 passes. When I tune I barely notice a small increase in the noise floor. If you have a lot of local pulse noise, you might want to turn on the P3s NB function to help. If Averaging is turned off, I can't think of a normal scenario where the noise floor would go up when tuning the band. It certainly does not here.

It is a great pair, but there are several annoying things. The one thing that I have issue with is the very poor ?sensitivity? of the PX3. I have 59 plus 10 signals on my KX3, however, on the PX3 waterfall the trace is very faint and indistinct. This is on a signal more than 20db above the noise floor !!! I really hate to have to compare, but on my Flex radio?s, you can see signals on the waterfall display that you can barely hear in the receiver.

For reference here it is again. Experimenting with the KX3 on WSJT FSK441 and JT65b I noticed looking at the spectral display of band noise that with the bandwidth widened fully out on DATA A Mode that even though it was displaying 4 KHz on the KX3 LCD, the bandwidth of the audio was less, like 400 Hz to 3600 Hz. On SSB mode it was possible to get the full 4 KHz by suitable manipulation of the width and centre frequency. It is useful on JT65 on EME if you are running a pileup from a rare DXCC to have stations spread out and having the full 4 KHz is beneficial then. Under normal circumstances not at all important, but I was just curious why DATA A mode is not giving the full 4 KHz while the SSB mode is. If I am missing some setting that is causing this please enlighten me. (I prefer using DATA A to the SSB Mode on WSJT as it does things like turn off TX equalisation and compression and other things like NR on RX which might upset WSJT). 73 David Anderson GM4JJJ > On 30 Jul 2015, at 23:24, Wayne Burdick wrote: > > I thought we'd hit the statute of limitations on this one.

For example on 144 MHz I have the PX3 NB on and it does cut out display of powerline noise, but as soon as a strong signal appears on the band the noise level bounces up and down way beyond the actual signal. So it is a balancing act like so many things. I don't have a problem with the sensitivity of the waterfall here, I will say the viewing angle is a big narrow and I do lose sight of the waterfall when not viewing it straight on sometimes.

I am using Tracking mode and have Averaging set at 14. I want to see the SSB pattern smoothly and not like an O'scope. I always slow the pattern down to see clearly the transmitted bandwidth and treble/bass balance. 2. I do not use Fixed mode, If I am tuning up the band I want to see whats ahead, in Fixed mode you can not. But the scope pattern stays '"clean" in Fixed mode, I wish it stayed "clean" in Tracking mode. When I say "clean" I mean Averaging does not revert back to 0 while tuning. John, ZS5J please note, on the Flex 6500 (and all 6000 series) that used SmartSDR software, the panadapter is in Fixed Mode (to use a Elecraft term) and can not be changed. This is the reason I no longer own a Flex 6000 series radio. I have tried the various Auto Adjust parameters in Fixed Mode, but they do not resolve my concern. Joe N9VX ------------------------------------------------------- Hi Joe - Do you have signal averaging turned on to reduce the noise floor?

Message-ID: <048501d0cb92$f46d9370$dd48ba50$@carolinaheli.com> My primary focus is DX and I'm trying to juggle priorities (cash) to build my station. I'm upgrading from a YAESU FT-897D which works ok but doesn't deal with noise/band noise well. The intended end result will be K3S, Panadapter, Amplifier, External Antenna Tuner. The K3S will have the sub receiver, cw filters, ssb filters, data mode filter. At this time I don't have the ability to upgrade my low band antenna's otherwise that would be my focus. Ideally my antenna's will be resonant on my operational bands but may need tweaking due to the bandwidth of the antenna. Current Antenna is the Buckmaster 7Band OCF 300W dipole installed per spec at 35'. All supported bands for this antenna have very good SWR except 10m and 6m (I believe a nearby tree is affecting the antenna and it will be trimmed soon). I'm shooting for the cheapest setup that will be functional at the start and then add on as I go. Trying to get the order of importance down. Thoughts: 1. Base K3S 10w - stay CW mostly due to lower power. 2. Upgrade to 100w 3. Add sub receiver 4. Add better receive only antennas, vertical loop array or such. 5. Add filters to receiver and subreceiver 6. Add Panadapter 7. Add additional filters if needed ? 8. Add amplifier (if I can hear it I want to be able to work it). 9. Antenna tuner Thanks in advance. I'd really love to just walk in and buy a fully stuffed setup at the start but I like to pay cash.

For that to happen on my PX3, I need to be in tracking mode. But the moment you swing the VFO, the display loses its averaging, and goes wild. When this happens you can no longer see where the station is that you were wanting to tune up to. So I end up spinning the VFO?. waiting for averaging to resume so I can find the station I want to tune to?and then spin the VFO again. I can only operate with averaging on all the time. The ?fixed mode? sort of/kind of fixes this, but the receive filter no longer stays centred in the middle of the display in this mode. And also, in Fixed mode, when it reaches the end of the display, it jumps back to the middle, and refreshes the waterfall - so any waterfall history that you had, is lost :( I have never used a Flex 6000 series radio, but I have been using, and still have the 5000A, 3000 and 1500. The system they use works just the way I want it - the RX filter remains centred in the display, and when you tune, the averaging remains on at all times. 73 John, ZS5J On 31 Jul 2015, at 3:08 PM, Joe Word wrote: Thanks to all that replied to my post. 1. I am using Tracking mode and have Averaging set at 14. I want to see the SSB pattern smoothly and not like an O'scope. I always slow the pattern down to see clearly the transmitted bandwidth and treble/bass balance. 2. I do not use Fixed mode, If I am tuning up the band I want to see whats ahead, in Fixed mode you can not. But the scope pattern stays '"clean" in Fixed mode, I wish it stayed "clean" in Tracking mode. When I say "clean" I mean Averaging does not revert back to 0 while tuning. John, ZS5J please note, on the Flex 6500 (and all 6000 series) that used SmartSDR software, the panadapter is in Fixed Mode (to use a Elecraft term) and can not be changed. This is the reason I no longer own a Flex 6000 series radio. I have tried the various Auto Adjust parameters in Fixed Mode, but they do not resolve my concern.

The P3 taps into the K3/K3S 8.2 MHz I.F., while the PX3 uses a baseband I/Q signal from the KX3. While both methods provide the basic benefits of a panadapter, the P3's implementation provides higher performance, using more expensive hardware, and is priced accordingly. The P3 is incredibly smooth in its tuning and presentation, and the unit is widely regarded as one of best panadapters available. Averaging, fixed-tune mode, noise blanking, peak detection and its many other features are all free of any sort of tuning noise or artifacts. If you're in "fixed-tune" mode, where the VFO/filter cursor moves across the screen, averaging information is preserved. There is no increase in the noise floor, no matter how fast you tune. In "tracking" mode, where the VFO/filter cursor stays fixed at the center of the screen, averaging information is reset when you tune. This has always been the case, but I'll mention this to our panadapter design staff and see if it might be possible to preserve the averaging data in tracking mode. In any case, I hope you can observe a P3 in action sometime. 73, Wayne N6KR On Jul 31, 2015, at 1:13 AM, John Kramer wrote: > I think I know what Joe is getting at?.and I agree with him, if I understand him correctly.

Maybe I should go and watch some youtube clips. I just thought the basic architecture in the P3 would be the same as my PX3. But, reading your last two paragraphs, tells me the issue I have with my PX3 also happens on the P3 - In tracking mode averaging info is reset the moment you tune. I find this loss of averaging when tuning, to be totally counter intuitive when trying to home in on a signal. It?s difficult to see a station, and find where you are trying to tune to, when the display loses its averaging.

But in Tracking mode, don't you lose waterfall history each time you tune? Regarding your PX3, have you tried positioning MKR A on the signal of interest, and then tapping the 'SELECT' knob on the PX3 to instantly take you there? By doing that, you won't lose track of that signal. If you decide you want to go back, push and hold the 'SELECT' knob to return to your previous frequency. 73, Dale WA8SRA > And also, in Fixed mode, when > it reaches the > end of the display, it jumps back to the middle, and refreshes the > waterfall - so any waterfall > history that you had, is lost :( > I have never used a Flex 6000 series radio, but I have been using, and > still have the 5000A, > 3000 and 1500.

Yes, in tracking mode you don?t lose your waterfall - BUT you lose your averaging when you tune. 2. If you want averaging to stay on all the time - tuning or not, then you can choose ?fixed?, but then the limitation with that mode, is that your VFO filter moves along the display, drops off the edge, and refreshes the waterfall history. I would like to see a combination of both, which is the way it works with Flex and PSDR - VFO receive filter remains centred, and does not move off to one side?.and at the same time, while tuning, averaging remains on all the time. Yes, I have tried the MKR option, but find it quite fiddly, lots of knob pushing to achieve something, so I generally don?t use it. 73 John, ZS5J C91J A25J On 31 Jul 2015, at 4:15 PM, dmb at lightstream.net wrote: John, It's true that in Fixed tune mode when you cross the boundary at either end of the current span, the screen refreshes to the new span and you lose your waterfall history.

My P3TXMON was shipped this week so ill get to play with it soon, but one would think the scale would be adjustable so that whatever power is seen, you could make that the full scale. This is just a scaling issue. Otherwise running the KPA500 with the 2000 watt sensor will only use one-quarter of the scale. Obviously the digital display still works right because no scaling is involved. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch ?

I believe I recall some comments here regarding saving my current K3 configuration to the K3 Utility in order to transfer it to the new K3S. Seems like the suggestion some time back was to change the serial number in the K3 configuration to the serial number of the new K3S then upload that saved configuration to the K3S.

If you go any further, you fall off the edge, and it plonks you back in the centre, the waterfall refreshes, and you lose your waterfall history. That?s okay ? Wouldn?t it be better if your VFO window remained centred in the pan adapter, even if you tuned up the band ? so you can see equally whats going on above and below your frequency ? Yes, you can do that in tracking mode?but then we get back to the issue of it resetting and removing the averaging feature. If you haven?t tried an SDR radio that can do both - ?fixed" and ?tracking" at the same time, perhaps you should try, and see what you?re missing out on. If the clever guys at Elecraft can come up with a firmware update that will allow you to do both?simultaneously, would you choose to rather have your VFO window jump off the edge every time you get to the end, as in ?fixed tune? ? Perhaps they could give us a menu choice of all three options - ?fixed tune?, ?tracking? and ?fixed tracking?. Would you stifle the opportunity of having this menu choice ? I better stop, I?m starting to feel like I?m repeating myself :-) Have a good weekend fella?s. 73 John On 31 Jul 2015, at 5:36 PM, Phil Wheeler wrote: I agree with Joe.

But cannot get the rig to key the amp as the needle on the rig's meter swings wildly to the right the moment i put the amp in Operate.

My station is a KX3-KXPA100 with a PX3. I have a quiet, to me, 30 amp switching power and a 2000 watt Honda generator that generates some, but not objectionable noise. The NB on the KX3 clears that up totally. I also have a 20 amp liner Astron power supply but it is heavy, bulky for use in a small trailer. And, it may be light for running an amp. I course I do not need to run it at 100 watts, either. I am trying to decide if it best to operate from the trailer's AC or directly from the batteries. And, if I use the batteries alone are there precautions I need to take. Of course, if available I would use "shore power". The AC from the trailer seems to be adequate when running with or without "shore power" or with my generator. I guess my real concern is the issue of using DC directly, and what should happen for protecton between my batteries and station. 73, Al ve7ear From jim at audiosystemsgroup.com Fri Jul 31 12:51:39 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Fri, 31 Jul 2015 09:51:39 -0700 Subject: [Elecraft] P3 vs SDR-IQ In-Reply-To: References: Message-ID: <55BBA79B.2050902@audiosystemsgroup.com> On Fri,7/31/2015 6:08 AM, Joe Word wrote: > 1.

What you want is not possible -- Averaging is working on the IF signal. We can choose to always center it, or tune across it. When we tune in Tracking Mode, it MUST begin averaging again. Suggestion: If you have not already done so, assign several Span widths and functions to the soft F-keys: What I find useful are 2 kHz, 10 kHz, 20 kHz, 60 kHz, 100 kHz, 200 kHz, Peak (Toggle On/Off), Fixed (Toggle On/Off). Once you've done this, try looking a bit wider as you tune. You may find that you can see things (like stations splattering). The P3 is a VERY versatile instrument. It's worth studying the Operating Manual to see all of the tools available. If you know what you're doing, it's possible to make some high precision, calibrated measurements. 73, Jim K9YC From bob at hogbytes.com Fri Jul 31 13:01:29 2015 From: bob at hogbytes.com (Bob N3MNT) Date: Fri, 31 Jul 2015 10:01:29 -0700 (MST) Subject: [Elecraft] [OT} Running a KX3 station from a holiday trailer In-Reply-To: <55BBA3BF.4070808@shaw.ca> References: <55BBA3BF.4070808@shaw.ca> Message-ID: <1438362089254-7605602.post@n2.nabble.com> I have run the exact same configuration from the TT battery with no issue.

Maybe a future firmware update will include an Auto option that will select whatever power level it sees like most power meters have. I have mine set to 2000w because I run a Command tech amp on 6m, but when I?m running the K3 by itself, the bar display is very low.. However, the digital readout indicates the correct power.

My P3TXMON was shipped this week so ill get to play with it soon, but one would think the scale would be adjustable so that whatever power is seen, you could make that the full scale. This is just a scaling issue. Otherwise running the KPA500 with the 2000 watt sensor will only use one-quarter of the scale.

Since 2004, I've been running all my gear on big 12V deep discharge batteries that I "float charge" with a regulated supply set for about 14 VDC. I've never found the need for any protection in line with the gear. We do the same on FD, except that we use solar panels to charge the battery. One thing I have run into with a K3 running from the 12V system in my 2006 Toyota Sequoia (big SUV). I was operating 6M with the motor off, and decided to start it. That somehow interrupted power to the K3 for a few seconds, which caused a microprocessor to lose its place. To get it going, I had to remove it from the 12V line and let it sit for a while (10-15 minutes). The K3 doesn't like its power to be interrupted. The root cause of the problem is that when you turn a K3 off using the front panel, it writes its current operating conditions to RAM. When you interrupt power with the K3 running, it can't do that. I don't know how this might relate to the KX3. 73, Jim K9YC From elecraft at mailman.qth.net Fri Jul 31 13:27:33 2015 From: elecraft at mailman.qth.net (Patrick Taylor via Elecraft) Date: Fri, 31 Jul 2015 17:27:33 +0000 (UTC) Subject: [Elecraft] KX3 Suite for Sale Message-ID: <1583059846.6653799.1438363653314.JavaMail.yahoo@mail.yahoo.com> I just ordered a K3s so I?want to sell my KX3 (fully loaded with all options including 2 m,MH3 mike, ant tuner, etc.).

It could keep the averaging for the portion of the spectrum that was displayed, and start new for the newly-displayed portion. Why throw away good data? Or, it could overscan and keep averaging for an invisible area beyond the edge of the display, then roll that into view as needed. Obviously, with either one, if you tune too fast, you get into an area with no averaging data. I?m really surprised that this is a new idea.

The K3S will have the sub receiver, cw filters, ssb filters, data > mode filter. I'm going offer a very different suggestion. For the cost of a 10W K3S, you can probably buy a fairly loaded used 100W K3 with 100W tuner and other accessories. Another $220 gets you the new K3SYNA board, which is about 90% of the improvement offered by the new K3S. You'll also want the KXV3B module, which includes a very nice preamp that improves performance on 10M and 6M. Both are easy to add. Now that 10M is dead most of the time and 6M E-skip season is nearly over, you won't need that preamp for a while. :) I'm speaking from experience -- I've done exactly those upgrades to my K3s, and have no plans to trade up to a K3S. You will find it a HUGE upgrade from your 897. 73, Jim K9YC From w3fpr at embarqmail.com Fri Jul 31 14:43:03 2015 From: w3fpr at embarqmail.com (Don Wilhelm) Date: Fri, 31 Jul 2015 14:43:03 -0400 Subject: [Elecraft] Incremental build /design suggestions?

Not only okay, it's what I prefer. As primarily a CW op, I tend to stick to the bottom 30-40 KHz of any given band. In my case, I don't care what's above the top of that range. What I DO care about is the positions of the stations within that 30/40 KHz window. After a few minutes of operation, I get to know who is where, (think of it as a band context) and when a new station appears, it is more easily noticed. As I tune around within that 30 KHz segment, the waterfall history of all signals is preserved. It's all about a stable context. > > Wouldn???t it be better if your VFO window remained centred in the pan > adapter, even if you tuned up > the band ? so you can see equally whats going on above and below your > frequency ?

Been there -- and still have an SDR1000, FLEX-5000A, FLEX6300, and HPSDR (original TAPR cards) sitting around here. The original PowerSDR's limitation of moving the band around while keeping the signal centered was a continual irritation. Once PowerSDR was re-written and the "CTUN" function was added, HPSDR and ANAN users were able to tune across a stationary band segment without losing context. I note that Flex Radio chose that method of tuning for SmartSDR and the 6000 series as well. I agree completely with Jim's (K9YC) last paragraph where he states that "The P3 is a VERY versatile instrument" -- and I've spent considerable time using and operating most of the significant alternatives.

I generally prefer the slide mode as it is less jarring and drags the window incrementally in the direction you are tuning. 73, Eric /elecraft.com/ On 7/31/2015 12:00 PM, dmb at lightstream.net wrote: > Hello John, > >> Phil >> >> So???.you???re okay using ???fixed tune??? where your VFO window moves >> off-centre, and heads off >> towards the edge of the screen - at this point you can???t see whats ahead >> of you because you???re >> near the edge of the pan adapter.

I believe I recall some comments here regarding saving my current K3 configuration to the K3 Utility in order to transfer it to the new K3S. Seems like the suggestion some time back was to change the serial number in the K3 configuration to the serial number of the new K3S then upload that saved configuration to the K3S. That seems straight forward enough. But wasn't there some kind of disclaimer comment regarding what would and would not transfer. Can anyone please clarify this for me.

My P3TXMON was shipped this week so ill get to play with it soon, but one would think the scale would be adjustable so that whatever power is seen, you could make that the full scale. This is just a scaling issue. Otherwise running the KPA500 with the 2000 watt sensor will only use one-quarter of the scale.

My P3TXMON was shipped this week so ill get to play with it soon, but one would think the scale would be adjustable so that whatever power is seen, you could make that the full scale. This is just a scaling issue. Otherwise running the KPA500 with the 2000 watt sensor will only use one-quarter of the scale.

Since 2004, I've been running all my gear on big 12V deep discharge batteries that I "float charge" with a regulated supply set for about 14 VDC. ? I've never found the need for any protection in line with the gear. We do the same on FD, except that we use solar panels to charge the battery. One thing I have run into with a K3 running from the 12V system in my 2006 Toyota Sequoia (big SUV). I was operating 6M with the motor off, and decided to start it. That somehow interrupted power to the K3 for a few seconds, which caused a microprocessor to lose its place. To get it going, I had to remove it from the 12V line and let it sit for a while (10-15 minutes). The K3 doesn't like its power to be interrupted. The root cause of the problem is that when you turn a K3 off using the front panel, it writes its current operating conditions to RAM. When you interrupt power with the K3 running, it can't do that. I don't know how this might relate to the KX3. 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 farrerfolks at yahoo.com From jim at audiosystemsgroup.com Fri Jul 31 17:33:57 2015 From: jim at audiosystemsgroup.com (Jim Brown) Date: Fri, 31 Jul 2015 14:33:57 -0700 Subject: [Elecraft] Incremental build /design suggestions?

First, Elecraft products in the K3 and KX3 generation are trivially easy to build. All the modules have been factory aligned and tested. They are "screw together" kits. Unless you have some physical disability that prevents you from building it, ALWAYS buy in kit form. It takes a day to build the 10W radio, another 3-4 hours for the 100W amp. The cost saving, typically around 10%, will buy an accessory or roofing filters. Second, I can't think of a good reason for the TCXO in the K3 unless you plan to do something quite special with the radio. The standard clock is quite stable. K3s are on lots of DXpeditions, and they are almost always within a few Hz of my dial readout for an even kHz. That is, if they say they are going to be on 14,027, they are on 14,027.000 unless they slid around to get away from lids. Third -- I have 1.8 kHz 8-pole roofing filters in my K3s, and I find them too narrow. I have a 2.1 kHz filter in my backup radio, and I like it better. If I were doing it over, I would choose 2.1 kHz filters. BTW -- the Elecraft webpage that shows prices is undergoing revision, and is currently missing prices for several important K3 and K3S options. 73, Jim K9YC On Fri,7/31/2015 11:13 AM, Bob McGraw - K4TAX wrote: > Here's my basic configuration which is on order at present: > > Item Ref.

I did run three lengths of #10 AWG automotive primary cable from the battery area to my operating position. Both the DC negative and DC positive lines each have a 30A Fast Blow fuse located very close to the battery. That third wire is a separate wire from the trailer ground, which is also near the battery to my operating position. This ground connects to the ground terminal on the radio. I do not rely on DC Negative for ground. Otherwise, there is an equal DC drop on the Positive wire and the same also on the Negative wire, thus the radio is above ground by that amount. Usually about 0.25 to 0.5 volts, depending on current. The inverter supplying DC and charging the battery, which is normally associated with the trailer, does/did produce some hash. Several donuts with 5 to 8 turns of wire located in the inverter box greatly reduced the hash. These were installed on the AC primary side of the inverter and the DC output of the inverter to the battery. This took replacing some wires to get the added and needed lengths to add the ferrite filters. I used RTV Silicone to hold each these in place thus preventing them moving when the trailer is in tow. All is quiet now. As to the Honda generator, the EI 2000 does produce some hash. I just operate off of battery and don't operate when the Honda is running. While I haven't tried it, Jim, K9YC has good suggestions for filtering the AC line coming from the Honda. In studying the topic, I would opt for putting the filter inside the Honda, if there is room. Otherwise, locate it as close to the Honda output as possible. 73 Bob, K4TAX On 7/31/2015 11:35 AM, Al Sather wrote: > Greetings > > I know this is a bit of topic but I this this list has the expertise > to give me good answers. > > My station is a KX3-KXPA100 with a PX3.

Please describe your symptoms to our customer support techs so they can give you a few simple things to check. One possibility is that the crystal filter offsets are not set up correctly. The offsets are marked on the filters (except 0.00 for all Inrad filters), and data can be viewed/changed in K3 Utility. 73, Wayne N6KR On Jul 31, 2015, at 12:03 PM, Olaf Matthaei wrote: > > > I build the K3s kit 10089 , all fine but I have low audo in speakers and > phones. > That means audio is beginning to hear on 3 o' clock position of AF gain > dial. > I AF gain is in the 5 o'clock position, autio is readable but distorted. > RF dial is in the 5 o'clock position.

The Accessory connection is used for FSK and PTT. You need it connected for PTT. Does fldigi transmit in RTTY (AFSK) or any other mode (MFSK, Olivia, etc.)?

Don't use "VGA" cables of any kind for any purpose other than connecting a VGA monitor directly to a computer! Use only full 15-pin cables, connectors and adapters except for the documented "interrupter" that some folks need when using external sequencers. I have a daisy chain of verified 15 pin Y adapters hanging on (for dear life) to the K3 ACC connector. It's a very delicate mechanical monstrosity but so long as I don't wiggle anything back there it does hold together and it works. They feed the KPA500/KAT500, a pair of band decoders, and some other stuff. The band decoders drive a pair of bandpass filters and a jury-rigged diode matrix for antenna switching via a Six Pak. (The pairs of things are because it's an SO2R station when I operate locally and I get my choice of two amps when operating remotely.) I switch the K3 9-pin RS232 connector with a two position rotary switch designed for serial ports. These switches are readily available from surplus stores and on-line. In the "Local" position, the K3 connects to the P3 which connects to the logging computer. In the "Remote" position, the K3 connects to the RRC. I also have a SteppIR controller eavesdropping on the serial communication on the radio side of the switch (center, switched port). I put it into General (frequency tracking) mode when I leave the house. I switch it to Ham mode and change bands manually when I'm in the shack. This arrangement works fine for the serial port except for extraneous clicks in the SteppIR controller when in General mode which I'm yet to understand fully. I think there is a significant amount of extraneous frequency and mode reporting on the K3 serial port. I can't hear it when I'm 200 miles away, so it doesn't bother me except for the possibility of wear and tear on the relays. I parallel the PTT and Key lines from the local external keyer and the RRC. I parallel the local mic with the mic output of the RRC. I use the PHONES jack on the KIO3 for local audio out and the SPEAKER jack for the RRC audio in. I have to remember to keep SPKR+PHONES set to ON for this. I run AFSK into Line In for local RTTY and so far haven't used RTTY remotely, but others do that, too. I can receive RTTY locally via K3 Line Out or remotely by feeding RRC speaker audio into a sound card at the control site. There's more switching and control logic and support software in there but it's not relevant to what you seem to be trying to do. It's complicated and the journey to get it all working was at least as intriguing as operating the thing. Keep at it. 73, /Rick N6XI On Fri, Jul 31, 2015 at 3:34 PM, RUSSELL J.
