However, I didn't like the prospect of transmitted power getting back into the shack via the existing feedlines, causing all kinds of problems including losses. From a surplus vendor I obtained four square slabs of ferrite (no spec's) and taped them together to form a box-shaped common mode choke around the existing feedlines (and rotor control cable etc). I didn't have radials at the tower base, but a couple of long and wide copper strips buried and connected to ground rods to which the tower was grounded. I opened up the tower ground connection and I had a feed point. Finding resonance was not as easy as using my antenna analyzer. The signal from the analyzer was overwhelmed by picked-up broadcast signals, rendering the analyzer unuseable. I got by using a custom measurement setup. It turned out that the entire metal tree resonated in the broadcast band and was inductive at 160. I tuned it with a serial variable capacitor, and found the antenna worked very well on 160. However, I didn't continue using it, as I didn't feel safe not to have the tower grounded. I pondered schemes to add some kind of gamma-like matching device, but never got around to it. Also I never tried it on 80, but I suspect it would not been ideal for low angle radiation. Later I added more antennas to the mast, and with the added cables, the whole bundle would no longer fit in the makeshift ferrite choke. Out of curiosity I once again tried ungrounding the tower to check on its characteristics as a vertical antenna. I could no longer find the resonance I had seen and used before. Apparently, the ferrite choke had been a crucial part of the scheme. At this point I still don't have an antenna for 160 or 80. (I did try an inverted vee off the tower for 80, but it caused terrible de-tuning of the 40m part of my beam on the tower, so I gave up on that. Maybe I should try a sloper.) I am thinking of putting up a dedicated vertical, but on my small lot it would couple to the tower. Perhaps it would be better to give the tower another look as my low-band vertical? My source of ferrite slabs dried up years ago. I wonder if anyone else on the list has used a similar approach and found a good way to choke off RF on a bundle of feedlines? Individual chokes don't seem very attractive to me as I have many cables, but if one has to go that route then it would make sense to look very carefully at the choice of chokes. I would also be interested in knowing about others' experiences with feed systems that leave the tower grounded. Thanks in advance for any useful ideas! 73, Erik K7TV From n1al at sonic.net Wed Mar 1 01:08:40 2017 From: n1al at sonic.net (Alan Bloom) Date: Tue, 28 Feb 2017 22:08:40 -0800 Subject: [Elecraft] Using your tower as a vertical - 160 or 80 In-Reply-To: <00a901d2924e$a4a8b570$edfa2050$@cox.net> References: <00a901d2924e$a4a8b570$edfa2050$@cox.net> Message-ID: <1e49719b-10ac-b50b-7239-ff12a51dd615@sonic.net> I use two of the top guy wires as an inverted vee.

On the K3 and later relays, the delay is adjustable. 8 msec is enough for most amps with GOOD relays (vacuum relays), but not enough for slower relays. Every rig I've used since getting back on the air in 2003 had that delay built in.

Your approach would provide 40m capability to replace the 40m capability that my (Sommer) beam loses through detuning. However, I wonder how hard your tuner must work on 40? Enough to create substantial feedline losses when the tuner is in the shack? Anyway, I have another reason not to choose your approach: I am rebuilding my station to support SO2R, and it is tough to avoid interference between the two radios operating on different bands, especially 40 - 20 and with the antennas close together. I found to my surprise, before the QST review came out, that the Low Band Systems multiplexer and band pass filters (my setup includes 40m) eliminates the interference problem. However, this scheme requires that the antennas be on a shared feedline. With your approach the 40m antenna would no longer be on the same feedline as the higher bands. -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Alan Bloom Sent: Tuesday, February 28, 2017 11:09 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Using your tower as a vertical - 160 or 80 I use two of the top guy wires as an inverted vee.

Running the K3 Utility I saw no extra spaces before or after the commands. If I executed them from the computer everything worked as expected. BTW, there are commands associated with the "Hold" of each button, so accidentally holding instead of tapping would have been obvious. Furthermore, as I said before, if I tapped for M1, I would see "MSG 1" appear on the display every time but sometimes the message (my callsign) would not be sent. So the command seemed to be reaching the radio. Just for completeness, since the K-Pod utility was on the same computer, I decided to reload the firmware. I restarted the K3 utility and for giggles placed a space in front of the M1 command string. It functioned normally. If I put a space after the command before the semi-colon, nothing was executed. I re-saved all of the macros and loaded them back into the radio. Things actually appeared to be better. I thought that maybe I fixed it. But sadly that's not the case. Like all intermittents, it's...well...intermittent. I also discovered that there is another idiosyncrasy (IMO). Perhaps it is intended, but when I tap M1 on the K3 for example, multiple times, the message (my call) is chained and sent as many times as I tapped the button. Doing this from the computer via the command tester works the same way. However, tapping the function key on the K-Pod a second time immediately ends the message. So I can't chain messages. Furthermore this seems to exacerbate the intermittent condition. At least I know how to turn off the beep.

The physical result is three parallel wires but electrically connected so as to form and "up, down and up again" element. This supposedly raises the radiating element impedance relative to the fixed ground loss resistance.

I saw this written up a few years ago as a means of increasing the overall efficiency of an inverted L for either 160 of 80 M. I had an "L" made of the smaller ladder line on 160 with only four ?? radials on the ground that seemed to work fairly well.

That means that nearly all radiation is from the vertical section, whereas in an inverted "L" arrangement there is considerable radiation from the horizontal section. Some ultimate "T" type antennas for H.F. were the very short verticals documented by Jerry Severt (W2FMI, SK) using umbrella-like multiple top hat loading with many "spokes".

Nope. And that's not "theory," that's someone's dumb idea. :) BUT -- using multiple spaced conductors in parallel and connecting them at both ends makes the conductor "thicker," which both lengthens it 1-2 percent and broadens the SWR bandwidth. The same thing happens with a tower as compared to a single wire. The vertical part of my 160M Tee vertical is a pair of #12 spaced about 9 inches. When I added the second wire, I observed that my SWR bandwidth approximately doubled. 73, Jim K9YC From mzilmer at roadrunner.com Wed Mar 1 12:48:34 2017 From: mzilmer at roadrunner.com (Matt Zilmer) Date: Wed, 1 Mar 2017 09:48:34 -0800 Subject: [Elecraft] list submission, using ham radio deluxe and logic with k3 and a laptop with only com3 In-Reply-To: References: Message-ID: Try LP Bridge?

The monopole is made of two or three wires. Feed is between one wire and the radial system while the second or third parallel wires are jointed at the "top" and retur to be connected to the radial system. A two-wire folded monopole presents a feedpoint impedance of between 80 and 150 ohms. Heys credits W6SAI in his book "Simple Low-Cost Wire Antennas" (Radio Publications, Inc., 1972) for a version made from slotted 300 ohm "twin lead". It is in Inverted L configuration for 80 meters: vertical 30 feet (9.1 meters) then sloping 25 feet (7.6 meters) to the top of a 35 ft (10.6 meter) support. To maintain resonance and compensate for the velocity factor of the twin lead, an 8 ft 3" (2.4 meter) single wire is run from the joined conductors at the end of the twin lead to the support. Heys describes a 3-wire version without a bend but sloping at an angle of 30 degrees or less from vertical at 65 feet (19.8 meters) centered on 3.6 MHz. Heys' version requires a 60 foot (18.2 meter) high support although he notes that for 40 meters a 30 foot support will be adequate. As with the two wire folded monopole all three wires are connected at the "top" and the feed point is between the center wire and the radial system. The other two wire ends are connected directly to the radial system. Heys notes that a spacing of 1 foot is needed to use the common 1/4 wavelength formula of 234/f (mHz). Heys says that either antenna can be used on its 3rd harmonic. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Charlie T, K3ICH Sent: Wednesday, March 1, 2017 5:25 AM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] 80 Meter Verticals Is there any truth in the theory of making the vertical radiator out of multiple wires such as ladder line and even adding a third wire woven through the ladder sections and fed on one wire? The physical result is three parallel wires but electrically connected so as to form and "up, down and up again" element. This supposedly raises the radiating element impedance relative to the fixed ground loss resistance. The idea I'm told, is that since the ground resistance (loss) is fixed at whatever it is but as the actual radiating element impedance is raised, the antenna becomes more efficient since the ground loss percentage of the overall feed point impedance is lowered. This impedance change happens in much the same way as a folded dipole feed is a higher impedance than a conventional dipole using a single wires. I saw this written up a few years ago as a means of increasing the overall efficiency of an inverted L for either 160 of 80 M. I had an "L" made of the smaller ladder line on 160 with only four ?? radials on the ground that seemed to work fairly well. My plan was to install elevated radials, but that would have been a LOT of wire around the yard.

I agree about the Alpha PIN diodes. I had an Alpha 86 for a few years, and never had any trouble with the PIN diodes -- and I made plenty of 'antenna mistakes'. I sold it because I was tired of waiting the 90 seconds for it to warm up, and I believed that Elecraft was about to release the KPA800 and 1500. I suspect some of the PIN diode failures were due to static discharges. I had ICE antenna protectors that provided a good DC path to ground and a good lightning ground system. Or else I was lucky. 73, Vic, 4X6GP Rehovot, Israel Formerly K2VCO http://www.qsl.net/k2vco/ On 1 Mar 2017 01:14, wb6rse1 at mac.com wrote: > The Elecraft KPA500 silent QSK is achieved without expensive PIN > diodes but rather with relatively inexpensive switching diodes.

A cage element connects everything together to make a fat, low-Q element. Those often have enough bandwidth to work over the entire 80m band. W1AW uses a cage dipole for 80m. A folded element is a bit shorter and has a higher impedance. It is also more broadband, mostly because of the fat elements, like a cage dipole. You can also use close-spaced parallel elements that are resonant at slightly different frequencies than the driven element. This is a different way to make a broadband antenna. This design has a name, but it escapes me right now. wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Mar 1, 2017, at 9:46 AM, Jim Brown wrote: > > On Wed,3/1/2017 5:25 AM, Charlie T, K3ICH wrote: >> Is there any truth in the theory of making the vertical radiator out of multiple wires such as ladder line and even adding a third wire woven through the ladder sections and fed on one wire? > > Nope.

For example, here's an article I wrote many years ago on how to homebrew your own: http://p1k.arrl.org/pubs_archive/89595 Those filters are only good for 100W or so, but there is no fundamental reason they couldn't be scaled up to 1500W.

If you shut down the computer completely, so nothing is sending commands to the serial port, does the delay still occur? Is CONFIG:AUTOINF set to NOR or to 1 (for a SteppIR, perhaps)? Maybe all those AI command outputs interfere with simultaneous commands sent from the K-POD? Note that if anything closes the PTT line after you press a memory button, the memory will halt immediately. Is that a possibility? Amp. keys radio? Does this intermittent behavior happen on both Phone and CW? Of course this won't apply to Phone unless you have the KDVR3 voice memory installed.

If tapping a K-POD button simply sends "SWT21;" to the radio (tap M1), why should it work any different when software sends SWT21; to the radio? Seems like message chaining should work the same as tapping M1. Perhaps it is a K-POD button de-bounce bug of some sort; with the K-POD occasionally seeing a double-tap of the button when only single tap is intended? 73, Bob, N6TV From dave.w0zf at gmail.com Wed Mar 1 16:19:01 2017 From: dave.w0zf at gmail.com (Dave Fugleberg) Date: Wed, 01 Mar 2017 21:19:01 +0000 Subject: [Elecraft] list submission, using ham radio deluxe and logic with k3 and a laptop with only com3 In-Reply-To: References: Message-ID: I've been playing with Win4K3 Suite lately...

All the failures occurred in a contest. #$%**&^@!))(# Why was that? Easy to see after cooling down and some minor reflection: 99% of my QSK is in contests because without CW traffic nets, that is the only place I need it. Which further means that 99.95% of the relay closures occurred in contests while I was still running amps running QSK. So what does that do to the odds of failure of the relay in a contest? Having an intelligent speed sensitive word spaced PTT rail, from the WinKey chip that knows when the string is actually starting and ending, means the amp clicks on at the beginning of the logger-generated character stream passed on by WinKey and clicks off at the end and there is never any hot-switching. I get to decide why I don't want to replace those relays based on my own reasons: Losing an amp in the middle of a great run in a contest p***es me off. Why in the middle of a great run? Where *else* would you expect to see the longest most intense QSK use of a T/R switching relay? The least amount of cooling off time matched with maximum heat stress? I can't throw around 80 pound things any more. I have to get one of the local grandsons or great nephews in for an evening to horse it out of the operating position for me, lug it to the workbench and then return it. Just too much work for my back. If I drop it I could really badly hurt myself. I have seen elder fellows in silly accidents like that turn an active life into a years-shortened bed-ridden one. And take risks to prove what? Win an argument about the QSK contest life-span of a Jennings vacuum relay? I hear very different stories than you put forward about the Alpha pin diodes. Congrats on on your pin diode success. Couple of fellas I know/knew had the same set of 8874's in their Alpha 76A's for the entire couple decades they owned them. But I have no basis to call their experience typical either. As to the switching diodes, as I hear rumors, the availability of less expensive and more reliable diodes for switching is but one of the reasons for the KPA500 power break at 500 watts instead of 1500. Those kinds of diodes were in my failed Ameritron QSK-5 box that I used with my Ameritron AL-1200. After the third diode blowout failure in the QSK-5, I gave up on it. It became clear that I was going to have to adjust everything to favor not blowing the QSK-5 diodes. So way back, W2CS and I decided to have an amp mod party and built a then-new AG6K QSK board into four of our amps. Interesting, the RJ1A style vacuum relay that wound up in W2CS' SB220 has lasted a decade still in service while a specific few RJ1A style relays in contest use on the same Dick Measures board did not made it for a year. As best as I could tell, the relay closure time goes long as the relay gets heated up and the resultant hot switching does the rest. It was clearly not the AG6K boards. I have a KPA500 and it is always used with my KAT500 which is preset for the band. It is my never-worry-about-incoming-SWR run up and down the band QSK S&P amp/tuner for 160 and 80. I have not forgotten the lessons from the QSK-5. On 160 the KAT can take the L/FCP up to 1925 and probably higher. Running the K3 QSK, hearing in between the dits on an RX antenna, and the 8410 T/R on the WinKey intelligent word space bridging PTT, there's just no good reason anymore to flagellate the 8410's T/R relay. Best of the fast and best of the slow at the same time. 73, Guy K2AV On Tue, Feb 28, 2017 at 6:16 PM wrote: > The Elecraft KPA500 silent QSK is achieved without expensive PIN diodes > but rather with relatively inexpensive switching diodes.

It is pretty good and the price sure is right however! I have switched to Win4K3Suite with com0com for the CAT sharing of the K3(s) and it has been rock solid. As others have mentioned, you can share the K3 CAT interface with up to 4 other applications and the lastest version of Win4K3Suite also adds 3 or 4 (off the top of my head) read only interfaces that you can use... i.e. like an SDA100 SteppIR controller or an Amplifier that will track the transceiver frequency. VSPE looks pretty good, but the license feed for the signed 64 bit version is ~$25 and that gets you half way to the cost of Win4K3Suite... Win4K3WSuite in and of itself is really nice. The more I use it, the more I like it... for example, pre defined RX EQ settings are so nice where you can just push a button and change the EQ settings on the K3 in a few seconds and if you are tweaking the EQ settings, you get to hear things live without having to leave the Config menu. Anyway, I'm really like the spectrum display to in combination with an LP-PAN2. It's become the replacement to NaP3. It's all together just a much more reliable solution than LP-Bridge and NaP3 IMHO. I can't live without my LP-PAN2 by the way... but now I no longer need to deal with LP-Bridge and Win4K3Suite starts right up with no delay where the com0com ports are created when Windows 10 starts up.

I do in fact recall seeing such an article in QST years ago. Assuming that you were just pointing out that I can put a bandpass filter on each feedline, as is common practice in SO2R operations, I need to state my case in more detail: Since I have second antenna covering 20-15-10 (a vertical), I started out doing just that: putting a bandpass filter on each. I was in a hurry and bought the LBS commercial filters rather than building based on the old article. The antennas are close together, and even after I upgraded so as to have two K3 radios, I was unhappy with the isolation with one K3 transmitting on 40 on the beam and the other K3 receiving on 20 on the vertical. Just out of curiosity I plan to dig deeper into this situation, as I think somewhat better results could be achieved. However, seeing the big difference in performance on a given band between the vertical and the beam, I really wanted both radios to have a beam. That is where I decided to get the multiplexer (a model that includes 40m). Performance wise, this was going to be like having one multiband beam, including 40m, for each radio. Much better than using the vertical for one radio, assuming of course that the physical sharing of one beam would aggravate the interference situation I had when using separate antennas and bandpass filters. With the multiplexer, per manufacturer's recommendation, each band still uses its separate bandpass filter, so that total attenuation between bands is much greater than what can be expected with bandpass filters alone. Still, I was apprehensive of a possible increase in interference. The outcome was nothing short of stunning: No interference at all. I see a possiblity that I could have somehow reduced the interference experienced with separate antennas and using bandpass filters, but I can't see that approach competing with the superior results using a single antenna + multiplexer + bandpass filters. The QST review backs up my assumption that the great results with that configuration was no fluke. Of course, I cannot include 80m in the same approach as long as I don't have a single antenna that includes that band (and I can't quickly get a multiplexer that includes all 5 bands). So, for 80 I will have a separate feedline and just a bandpass filter. BTW I am very happy to not have yielded to the temptation to upgrade my beam to a Steppir, as the multiplexer approach requires the antenna to be tuned simultaneously to multiple bands, not to tune to one band at a time. If I had been able to achieve really good isolation with just a bandpass filter for each band, your approach with an 80m antenna that also covers 40 would make good sense to my situation. As it is, keeping 40m within the beam, even with no gain over running 40m on the second antenna, makes sense as it allows me to route 40m not just through the bandpass filter, but also through the multiplexer. Since I already tried an 80m inverted vee on the tower, and it ruined the 40m performance of the beam, I am looking for other approaches for 80m. It might be possible to change the beam to bring it back to resonance on 40, but this particular beam is a complicated design already. A sloper is one possiblity, but it is not likely to be my first attempt, as it would be close to the beam and it would be somewhat similar to the vee. At this point I am leaning toward either a separate shortened vertical such as a Butternut model for 80 and 40 (not likely to use the 40 part) or using the tower itself as a vertical. For the latter approach I would need to prevent the tower's feedline bundle (the part going into the house) from forming part of the radiating element. I remember an old Antenna Book discussing methods of feeding the tower as a vertical, but the author seemed to ignore the issue of the cables coming off the tower. Maybe it was assumed that the cables would be disconnected at the bulkhead whenever the tower would be used as a vertical. Nobody has replied to me about experiences dealing with that issue. Also as the tower with its antennas is resonant in the BC band, I would model it to find out if it has a resonable vertical radiation pattern if fed as a whole on 80. 73, Erik K7TV -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Alan Bloom Sent: Wednesday, March 01, 2017 12:29 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Using your tower as a vertical - 160 or 80 Hi Erik, It is certainly possible to use a separate filter in the feedline to each antenna. For example, here's an article I wrote many years ago on how to homebrew your own: http://p1k.arrl.org/pubs_archive/89595 Those filters are only good for 100W or so, but there is no fundamental reason they couldn't be scaled up to 1500W.

The tower is topped with HF and VHF yagis which act as a capacitive top hat. The 50 Ohm coax feedline is connected to a tap on the coil of a parallel tuned circuit. The top of the LC circuit is connected to a #16 THHN wire which runs parallel to the tower, about 18" outside one of the legs and connects to a bolt around 10 ft down from the top of the tower. At the base of the tower I simply tune the capacitor and find the best spot on the coil to tap to obtain the lowest SWR. There are 16 quarter wave radials around the tower, most of them on the tower side of the house from south to north and a few wrapping around and under the back deck toward the northeast. There are around a dozen 8 ft ground rods connected to the tower with #6 wire and the tower also is connected to a perimeter ground system surrounding the house. The shields of most, but not all, of the coax cables leaving the tower are grounded at the tower base. Before all coax and control cables enter the shack they all are grounded at the steel entry box around 30 feet from the tower base. So how does a shunt fed 75 ft tower work with a barefoot K3 feeding it? With 100 Watts I've confirmed 229 countries on the Topband and have worked 89 countries on all continents with QRP 5 Watts. You can check out the 160M QRP WAC cards at: http://www.qrz.com/db/K1HTV If you haven't tried shunt feeding your grounded tower, give it a try. You may be surprised at how well it can work on 160 Meters. 73, Rich - K1HTV = = = Erik, K7TV wrote: Years ago, after putting up a heavy-duty crank-up tower with several antennas on a tall mast at the top, I was interested in loading up the whole metal tree for 160 and/or 80.

So there is pretty regular bus activity. When I disable LP-Bridge it *appears* to resolve the issue. I hedge, since this is an intermittent problem. There is no other stuff going on, I use a KPA500 and KAT500 cabled normally with AUX cables. No PTT, foot switches, etc. Strictly VOX operation. It's not an RF problem; verified by putting the K3S in test mode. All of the function buttons seem to be affected. I have one set so tapping turns VOX on or off. It fails too. I'm glad Bob concurs that a simple command should not terminate prematurely when another command is initiated. Chaining should work. So I see two birth defects here that need fixing.

Threshold and slope combine to form a point of non-linearity that can cause all sorts of in-band mixing products when multiple signals exist at roughly the same levels. I and others have experienced that first hand in the past. I can running stations in a contest with a fairly narrow passband and if I get more than a few callers at roughly the same level, and if that level is in the vicinity of the knee in the gain curve formed by the onset of the AGC, the A-2B and 2A-B (etc) products generated by the nonlinearity create all sorts of mush that muddles the copy. Noise at that point in the curve can perform similar dirty deeds. I use as little AGC slope as possible with a fairly high threshold as a result ... tough on the ears sometimes but helps the rate dramatically. If I remember correctly, even without the AGC there is a knee at the low end of the response curve (but still above the noise limit) in the original synths. I recently purchased the new synths for my K3 and supposedly they help significantly on that score, but I haven't had the opportunity to install them yet. 73, Dave AB7E On 2/28/2017 4:37 PM, dave wrote: > > My thoughts on this are that those who are concerned about the slope > and threshold settings are barking up the wrong tree.

Something similar to your shunt feeding method is what I have had in mind. Since my tower is a crankup (55 ft topped by about 22 ft of mast+antennas), I do have some misgivings about managing the wire running parallel to the tower, in the scenario where the tower sections are telescoping and releasing the tension on the wire. Maybe I should first try attaching the feed to the top of the bottom section rather than the top of the tower. The most interesting part of your installation is your grounding of most of the coax cables at the tower base, and also at the entry box. When I installed my tower in 1993 I had read a recommendation to let the cables form a gentle curve almost touching ground, which is what I did. The idea of grounding them at the tower base did not occur to me, and doesn't seem compatible with the gentle curve concept. At the house I did think about feedthrough panel that could be grounded, but I was in a hurry and didn't do the work. Some of my vhf/uhf cables are of the thick variety (much thicker than RG-213, and extra connectors cost significant money. Since then, it has been on my to-do list to go back, cut the cables, install connectors, and install a grounded plate or box. At the time when I wanted to try the tower as a 160 vertical, I didn't feel confident that doing that work would be as effective as choking off common mode currents with ferrites, and that did seem to work well as long as the cables fit in the device. After reading your post I get the impression that instead of obtaining choke(s) for the cable bundle as it is today, I should do the work of grounding the cables at the house entry and also at the tower base. For non-coax control cables I could apply my choke. You state that not all of your cables were grounded. For such a situation my first thought is that the result would depend on cable length and frequency, and if there is no problem in your situation then luck might have played a role. You did not mention trying your setup for 80. In my case, I have more need for 80m than 160, and I am still unsure if the whole metal tree might be on the big side for 80. That should be easy to determine with a model. Thanks for the details of your ground system. If I were to erect a separate vertical for 80, I would have to install a lot of radials, so doing the same around the tower is not a big deal. Like in your case, most of the radials would be on one side of the tower (directed away from the house). When I did feed the tower on 160 as an experiment years ago, I had (and still have) just two ground rods at the base, plus copper ribbon, which was meant to encircle the house, a project that was never finished, but has been on my to-do list ever since. I see a lot of similarity with your situation, but I need to put in some work to catch up! Now, supposing I get it all done, and it all works as expected, the next step is seeing the resulting 80m capability in the context of a 2-radio system. Obviously, only one radio can be on 80 at a given time, and it will use a bandpass filter but not a multiplexer. The 80m antenna (=tower) will be closer to the beam than my high-band vertical.The 80m rf will flow in very close proximity to the beam, the use of which by another radio is protected by both the multiplexer and the applicable bandpass filter. Will that be enough protection, given that the proximity situation is worse than with the high-band vertical? I am not totally sure, but it seems a reasonably good bet to me. 73, Erik K7TV ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- ------------------------------------------- Erik, I've been feeding K3 RF to my house bracketed, 75 ft Rohn 25 tower for years with great success on 160 Meters. The tower is topped with HF and VHF yagis which act as a capacitive top hat. The 50 Ohm coax feedline is connected to a tap on the coil of a parallel tuned circuit. The top of the LC circuit is connected to a #16 THHN wire which runs parallel to the tower, about 18" outside one of the legs and connects to a bolt around 10 ft down from the top of the tower. At the base of the tower I simply tune the capacitor and find the best spot on the coil to tap to obtain the lowest SWR. There are 16 quarter wave radials around the tower, most of them on the tower side of the house from south to north and a few wrapping around and under the back deck toward the northeast. There are around a dozen 8 ft ground rods connected to the tower with #6 wire and the tower also is connected to a perimeter ground system surrounding the house. The shields of most, but not all, of the coax cables leaving the tower are grounded at the tower base. Before all coax and control cables enter the shack they all are grounded at the steel entry box around 30 feet from the tower base. So how does a shunt fed 75 ft tower work with a barefoot K3 feeding it? With 100 Watts I've confirmed 229 countries on the Topband and have worked 89 countries on all continents with QRP 5 Watts. You can check out the 160M QRP WAC cards at: http://www.qrz.com/db/K1HTV If you haven't tried shunt feeding your grounded tower, give it a try. You may be surprised at how well it can work on 160 Meters. 73, Rich - K1HTV From jim at audiosystemsgroup.com Thu Mar 2 01:45:08 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Wed, 1 Mar 2017 22:45:08 -0800 Subject: [Elecraft] RX Mush, why the fuss?

I ran two wires out my window, one down to the base of the mast and one to a point on it that produced a reasonable SWR on 80 meters. The rotor cable and feedline for the beam ran down to the ground, and then back up to the shack. No ferrites or anything on the feedline. I wrapped the rotor cable around a ferrite rod at the rotor controller. I had a system of 16 radials, each about 20' long, and in a half-circle. I ran about 600 watts to this arrangement and didn't notice RF issues in the shack. It worked surprisingly well, producing contacts from here into the US as far west as Illinois. 73, Vic, 4X6GP Rehovot, Israel Formerly K2VCO http://www.qsl.net/k2vco/ On 2 Mar 2017 05:21, Erik Basilier wrote: > Hi Alan, > > Your link didn't work for me, but I assume your article describes how to > make a good bandpass filter.

This is a form of gain compression, which is distortion, strictly speaking. The 'landmark' paper on this was written by Jack Smith, K8ZOA, available at: http://www.cliftonlaboratories.com/elecraft_k3_agc_and_s-meter.htm . In it, Jack showed that the K3's curve of Audio Output vs. RF Input at Slope = 15 acts as a hard limiter. He follows that with a table of measurements where a 10 dB change in RF signal level results in virtually no increase in audio output. This 10 dB change in RF signal level could come from a single signal that increases by 10 dB, or additional signals in the passband that add 10 dB of RF input to an existing 'strong' signal -- the receiver doesn't care which. For many listeners, more signals added to the passband that don't result in any more audio is a condition that confuses and fatigues the brain and can make it difficult to decode the relationship between signals. I believe this is the 'mush' that has been reported here. The effect occurs on CW, too, though I believe that the effect is made even worse by the heavily compressed phone signals that many contesters generate. I completely agree with Dave AB7E that the use of as little slope as possible (lower values of the AGC Slope parameter), coupled with higher values of AGC Threshhold allows the receiver to sound very natural, or open, or clean, and preserves as much as possible the relationship between multiple signals, which makes it easier for your brain to copy them. (I'm sorry for using such non-scientific terms, but it's the best I can do to describe it.)

Obviously 43-feet vertical is very short on 495-KHz (less than 10% of a quarter wave), so the antenna is heavily base loaded by a coil plus the 122-foot top section adds a little capacity. I ran three wires in parallel spaced a foot apart in the vertical section tied together at both ends with 1/2 inch copper tube and the top hat is two parallel wires space 2-foot with another 1/2 inch copper tube at the far end. This lowered the Q enough to get SWR<2.0 over 5-KHz bandwidth. I will have to retune to 472-479 KHz when I hang the antenna back up after repairs as this is the proposed frequencies for a future ham band.

Run a wire vertical up one side of your tower separate say 6-12 inches from the wire shorted over to the tower top. Tower stays grounded and your wire it fed at the bottom near ground but insulated. Coax shield is tied to tower ground. Depending on tower height you still may need a tuner to match it. 80m works nice with 60-foot tower. You still need ground radials like any 1/4 wave vertical. The tower makes a nice fat element to lower Q. If you have a mast with HF antennas at top there will be a little capacitive loading to the resulting vertical. 73, Ed - KL7UW Date: Wed, 1 Mar 2017 10:41:40 -0800 From: "Ron D'Eau Claire" To: "'Charlie T, K3ICH'" , Subject: Re: [Elecraft] 80 Meter Verticals Message-ID: <003501d292bb$780e04d0$682a0e70$@biz> Content-Type: text/plain; charset="utf-8" John Heys, G3BDQ, in his book "Practical Wire Antennas" describes "folded monopoles" or "folded Marconi" antennas - essentially 1/2 of a folded dipole worked against a system of radials. The monopole is made of two or three wires. Feed is between one wire and the radial system while the second or third parallel wires are jointed at the "top" and retur to be connected to the radial system. A two-wire folded monopole presents a feedpoint impedance of between 80 and 150 ohms. Heys credits W6SAI in his book "Simple Low-Cost Wire Antennas" (Radio Publications, Inc., 1972) for a version made from slotted 300 ohm "twin lead". It is in Inverted L configuration for 80 meters: vertical 30 feet (9.1 meters) then sloping 25 feet (7.6 meters) to the top of a 35 ft (10.6 meter) support. To maintain resonance and compensate for the velocity factor of the twin lead, an 8 ft 3" (2.4 meter) single wire is run from the joined conductors at the end of the twin lead to the support. Heys describes a 3-wire version without a bend but sloping at an angle of 30 degrees or less from vertical at 65 feet (19.8 meters) centered on 3.6 MHz. Heys' version requires a 60 foot (18.2 meter) high support although he notes that for 40 meters a 30 foot support will be adequate. As with the two wire folded monopole all three wires are connected at the "top" and the feed point is between the center wire and the radial system. The other two wire ends are connected directly to the radial system. Heys notes that a spacing of 1 foot is needed to use the common 1/4 wavelength formula of 234/f (mHz). Heys says that either antenna can be used on its 3rd harmonic. 73, Ron AC7AC 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From Martin at The-Wallers.Net Thu Mar 2 04:14:53 2017 From: Martin at The-Wallers.Net (Martin Waller) Date: Thu, 2 Mar 2017 09:14:53 -0000 Subject: [Elecraft] Afsk a In-Reply-To: <28ec0ae6-41d3-1a5f-f86d-cfdadda74726@embarqmail.com> References: <5190CA11-43B5-4583-A074-5ED5E148CABC@The-Wallers.net> <28ec0ae6-41d3-1a5f-f86d-cfdadda74726@embarqmail.com> Message-ID: <003901d29335$743adc50$5cb094f0$@The-Wallers.Net> Many thanks for all the replies.

OmniRig is the sole user of the COM port connected to the radio, but it can share out it's resources to several programs at once by other means in software, so long as the other programs are written to use OmniRig as a radio interface. That is good. BUT! Only one other program can in reality "control" the radio at any one time *, though all of them can poll for it's status. OmniRig will return the last known data, without necessarily actually polling the radio, if not needed. That can also speed things up a lot with some software and a rig that is otherwise slow to respond. If your rig of choice is not listed, then read the OmniRig pages on Alex's site, and learn how to craft your own driver file. It's not difficult, it just needs some thought, and time. HamLib is a similar system, but I find tends not to work that well on Windows. (It does work well under Linux though.) YMMV however. * It doesnt matter what or who's rig end user control software you use, the rig itself is a simple single task machine. If you start to throw multiple commands and queries at it from different programs via a COM port sharing tool, at best everything will be confused. At worst, you'll probably crash the radios own internal firmware! That is what HamLib, OmniRig, and Flrig etc are intended to provide. A "managed" way to share information, and apportion control when needed. Take care. 73. Dave G0WBX.

I had tried Win4K3Suite one day. I did not spend much time with it, but two things didn't seem right. Maybe I just didn't know what I was doing though. It seemed each time I started the program I lost the equalizer settings and had to reenter them. Also there was an issue about the resolution had to be set to 3 decimal places. I would rather have the resolution to two decimal places for CW and for SSB depending if I am running or just going up and down the band I want to have 1 or two decimal places. And again, maybe I just didn't know what I was doing. And since LP-Bridge handles all of my devices fine I didn't get too serious with Win4K3Suite. I have the P3 with external monitor so not too interested in another band scope. The one thing I can't seem to do with LP-Bridge is have the Acom 2000A track my K3's receive frequency in order to pretune. I have N4PY's program doing that in the background. Tell me I didn't do things correctly and that if I set up Win4K3Suite properly I can just start the program and it will start my other interface programs such as N1MM+, DXBase, AXETTY, like LP-Bride and be seamless. 73, N2TK, Tony -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of M.

As others have mentioned, you can share the K3 CAT interface with up to 4 other applications and the lastest version of Win4K3Suite also adds 3 or 4 (off the top of my head) read only interfaces that you can use... i.e. like an SDA100 SteppIR controller or an Amplifier that will track the transceiver frequency. VSPE looks pretty good, but the license feed for the signed 64 bit version is ~$25 and that gets you half way to the cost of Win4K3Suite... Win4K3WSuite in and of itself is really nice. The more I use it, the more I like it... for example, pre defined RX EQ settings are so nice where you can just push a button and change the EQ settings on the K3 in a few seconds and if you are tweaking the EQ settings, you get to hear things live without having to leave the Config menu. Anyway, I'm really like the spectrum display to in combination with an LP-PAN2. It's become the replacement to NaP3. It's all together just a much more reliable solution than LP-Bridge and NaP3 IMHO. I can't live without my LP-PAN2 by the way... but now I no longer need to deal with LP-Bridge and Win4K3Suite starts right up with no delay where the com0com ports are created when Windows 10 starts up.

There is a huge difference between AGC action (which is simply a reduction in gain with linearity retained) and hard limiting. I have read the article and agree that his measurements are very helpful. The "waviness" he observes he correctly attributes to the log function in the DSP being less than accurate. This has since been corrected as far as I know. Whatever some people at the receiving end of a CW pileup hear is not caused by hard limiting. Why can't we ever see some hard evidence of this phenomenon (like a video with quality audio or at least an audio only recording)?

I ran two wires out my window, one down to the base of the mast and one to a point on it that produced a reasonable SWR on 80 meters. The rotor cable and feedline for the beam ran down to the ground, and then back up to the shack. No ferrites or anything on the feedline. I wrapped the rotor cable around a ferrite rod at the rotor controller. I had a system of 16 radials, each about 20' long, and in a half-circle. I ran about 600 watts to this arrangement and didn't notice RF issues in the shack. It worked surprisingly well, producing contacts from here into the US as far west as Illinois. 73, Vic, 4X6GP Rehovot, Israel Formerly K2VCO http://www.qsl.net/k2vco/ From chandlerusm at gmail.com Thu Mar 2 16:46:13 2017 From: chandlerusm at gmail.com (Chuck Chandler) Date: Thu, 2 Mar 2017 15:46:13 -0600 Subject: [Elecraft] P3 menu to set ref level?

Even though the strongest signal in the passband will control how much AGC is applied, weaker signals in the passband should sound proportionally weaker. Now that you mention hard limiting, there is a limiter in the K3 that if turned on will protect your ears. I am wondering if some instances of reported receiver mush did have limiting set on - that would be particularly true for those who chose to ride the RF Gain and/or run with AGC off. 73, Don W3FPR On 3/2/2017 3:37 PM, ab2tc wrote: > Hi, > > Where in Smith's article does it say that AGC with the slope set for 15 acts > as a hard limiter?

In LP-Bridge, the read only outputs are hard coded to the kenwood protocol at 4800 baud. So you can use LP-Bridge to get your ACOM 2000a to track your K3 if you set the ACOM 2000A to Kenwood on the radio interface. I had this configured and working on Jim's W7CT's setup a few months back. I exchanged a few emails with Larry N8LP and he pointed out the hard coded Kenwood / 4800 baud protocol on the output option in LP-Bridge. Like you I didn't get excited about Win4K3Suite at first and I too saw the RX eq settings reset. But after thinking through it, I love the RX eq settings being controlled by Win4K3Suite now. There is no way to do that from a K3 macro as far as I know... on the RX side. So with Win4K3Suite, you can store RX eq presents and switch between them on the fly AND you can change the RX eq settings in real-time and hear the change, you can't do this via the Config menu. It does take a few seconds for Win4K3Suite to manipulate the RX eq settings because it's doing some tricks to change the settings on the fly. The reason Win4K3Suite resets the eq settings is because there is no way to read the settings from the K3 to store them in the first place... so it resets the settings for TX and RX eq at start up and then once you change them in W4K3S and exit Win4K3Suite it stores them in the Win4K3Suite config on disk... so then the next time you start up, it restores the settings to your K3. I was annoyed by this until I read Tom's FAQ here: http://va2fsq.com/faq/ Then the light turned on. There is no way to read settings from the K3 eq, so to externalize this, Tom is working around that limitation. Once you set them up in W4K3S you are golden. And it's a major bonus to changes those on the fly as I have described. BTW, I'm just a happy user of W4K3S if you are wondering... I have no reason to try and tout it other than I have been happy with the updates and support. Even if you don't use the spectrum display in W4K3S, based on my many year experience with LP-Bridge and NaP3, I still think it's well worth it on how it shares the K3 CAT data. It has been totally reliable too... Anyway, give it another try.... and play around with the multiple and dynamic UI settings for the eq in your K3.

I have had a KX3 for two or three years. I replaced one of the high end rigs with it and am very pleased with the results. I have a full quarter wave elevated ground plane antenna for 160. I?ve had it up for 27 years. It is made from Rohn 45 with a Rohn insulator broadcast section inserted so the insulators are 27 feet above ground. There are 14 sections plus a short base and short flat top section. The antenna is tuned with a 14 foot piece of 4 inch irrigation pipe out the top, which is adjustable. The over all height of the antenna is 150 feet. At the 27 foot level there are 7 full quarter wave radials. There were eight, but one broke and is in the woods somewhere and I can?t find it. The radials droop to 10 feet above ground at the perimeter. It doesn?t hurt that I live on a ridge which is the highest point in the county and my QTH is 300 feet or so above average terrain for 30 miles in every direction. The antenna is excellent. I don?t own an amplifier for any HF band. I work everything I hear and I hear lots. I have worked JA and VK/ZL with 100 watts on 160. This year I decided to try QRP, 5 watts. I operated ten hours, just tuning to stations and calling them. They usually came back on the first call. I worked as far East as CN2 in Morocco and west to KH6. I made 250+ QSOs and 58 multipliers. From what I saw on the CQ160 scores page before they took it down, I had a top ten in NA and top 25 world score. Maybe next year I will make a serious effort. All depends on how I feel. My health is great. My motivation is lacking after 60 years on the air and more contests and DX QSOs than I can count. I run the attenuator on receive all the time. I leave the RF gain all the way up. I turn the Bandwidth down to 100 or 150 hz and seldom have noise or QRM problems. The receiver is the best I have ever owned. I think back to my first receiver, a dual triode super regen that heard the entire 80M novice band without touching the tuning and I think ?We?ve come a long way, baby!!? 73 all, Dave, K4TO From alorona at sbcglobal.net Thu Mar 2 23:16:24 2017 From: alorona at sbcglobal.net (Al Lorona) Date: Fri, 3 Mar 2017 04:16:24 +0000 (UTC) Subject: [Elecraft] RX Mush, why the fuss?

I fear this is going to get bogged down in definitions. From Wikipedia: "Limiting can refer to non-linear clipping, in which a signal is passed through normally but 'sheared off' when it would normally exceed a certain threshold. It can also refer to a type of variable-gain audio level compression, in which the gain of an amplifier is changed very quickly to prevent the signal from going over a certain amplitude. * Hard limiting ("clipping") is a limiting action in which there is * (a) over the permitted dynamic range, negligible variation in the expected characteristic of the output signal, and * (b) a steady-state signal, at the maximum permitted level, for the duration of each period when the output would otherwise be required to exceed the permitted dynamic range in order to correspond to the transfer function of the device." AGC of the type we're discussing falls under this definition, and not the non-linear "back-to-back diode" clipping you might be thinking of. Look at the first graph under the section titled "Adjusting AGC SLP" and observe that for Slope=15, above about -104 dBm, the output follows a horizontal line. Moreover, the very first table that follows that graph shows that with Slope=15 if the input increases by 10 dB the output increase is virtually zero. That transfer characteristic is what audio engineers call "hard limiting". I also fear we may be talking past each other when we say 'linear' and 'nonlinear'. The AGC curve is 'nonlinear' in the sense that if we pour more RF input into the receiver, the output doesn't get any bigger. It's like that by design. All I was saying is that it doesn't sound good to me. I'm very happy there is Slope = 5. Call it whatever you want; the curve speaks for itself. Al W6LX >>> There is a huge difference between AGC action (which is >>> simply a reduction in gain with linearity retained) and hard limiting.

Actively using RF gain, ATT, PRE, as one should, makes the S-meter even less interesting. Eyes tend to spend a lot of time on the P3 display when available. Spectrum peaks don't show how close we are to the maximum ADC input level. How about adding more information to the P3 display? Besides the existing display of the DSP bandwidth, the width of the roofing filter could also be shown in a similar way. And to address the hardware AGC function, how about some kind of vertical thermometer showing how close we are to it kicking in? Perhaps a horizontal line across the vertical bandwidth ribbon could show this, with the top of the bandwidth ribbon representing saturated ADC or hardware AGC activation. Just an idea. 73, Erik K7TV ---------------------------------------------------------------------------- --------------------------------- One problem here is that a lot of the discussion has been in analog terms.

One set of comments indeed involved complaints about the hard limit at the upper end that has nothing to do with AGC. It is, as you say, simply a hard limit ... pretty much a clipper to protect the ears (and maybe also to help protect the output stage in the speaker driver before that issue got addressed). That creates a distortion, but it's not really what I would describe as "mush." The nonlinearity I described in my earlier post was at the opposite end of the curve ... down where the AGC just begins to kick in. As W6LX says, it's a nonlinearity in the curve, and no matter what you call it that contributes to the generation of mixing products from multiple signals that happen to be at roughly the same level within the passband. The low end of Jack Smith's plots showed that pretty clearly. During some of my contest runs, individual signals were perfectly clear and distinguishable, two not terrible, but even three signals could generate enough mixing products to cause problems if they were low enough in volume and close enough in frequency. Since I typically operate with a very narrow passband (about 150 HZ on CW), the mixing products end up very close to the real signals. For example, 2x500Hz - 510 Hz gives another phantom signal at 490 Hz. Things get really messy with three or more signals. It is also, possible, of course, to get mixing anywhere there is a knee in the AGC curve, but if you put the knee up higher there is less likelihood that multiple signals will be of the same amplitude to cause a problem (one will dominate), and their amplitude swings will range further afield of the knee ... meaning that a lower percentage of the energy will be mixed. At the low end, you're pretty much screwed ... any signal you hear will be at that nonlinearity and the amplitude swings will be small enough that they spend all their time in the nonlinearity. As I said before, reputedly the new synths greatly improve this. The bottom line is that if you have two or more signals within a passband that traverse a nonlinearity, you get mixing products within the same passband that blur the individual signals ... i.e., "mush." And since the mixing products on CW only occur when both (or more) of the signals are keyed, the mixing products aren't even intelligible. ;) At least this is how I understand the situation. I'd be happy to get corrected if my comments are flawed. 73, Dave AB7E On 3/2/2017 3:19 PM, Don Wilhelm wrote: > > Now that you mention hard limiting, there is a limiter in the K3 that > if turned on will protect your ears.

When I get home will check out the Acom/LP-Bridge interface. I have both K3?s set up similarly ? one set of settings for CW and one set for SSB, which the K3 remembers. I have not changed them in a long time and see no reason to change them frequently. Both rigs are set up for contesting and DXing. LP-Bridge gas been very reliable. Looks like I may stay with it for now once I get the Acom setup with it. Yes, once I send a dit the Acom will setup, but I like the idea that it is tracking my receiver. 73, N2TK/NP2 (KP2M), Tony From: M.

In LP-Bridge, the read only outputs are hard coded to the kenwood protocol at 4800 baud. So you can use LP-Bridge to get your ACOM 2000a to track your K3 if you set the ACOM 2000A to Kenwood on the radio interface. I had this configured and working on Jim's W7CT's setup a few months back. I exchanged a few emails with Larry N8LP and he pointed out the hard coded Kenwood / 4800 baud protocol on the output option in LP-Bridge. Like you I didn't get excited about Win4K3Suite at first and I too saw the RX eq settings reset. But after thinking through it, I love the RX eq settings being controlled by Win4K3Suite now. There is no way to do that from a K3 macro as far as I know... on the RX side. So with Win4K3Suite, you can store RX eq presents and switch between them on the fly AND you can change the RX eq settings in real-time and hear the change, you can't do this via the Config menu. It does take a few seconds for Win4K3Suite to manipulate the RX eq settings because it's doing some tricks to change the settings on the fly. The reason Win4K3Suite resets the eq settings is because there is no way to read the settings from the K3 to store them in the first place... so it resets the settings for TX and RX eq at start up and then once you change them in W4K3S and exit Win4K3Suite it stores them in the Win4K3Suite config on disk... so then the next time you start up, it restores the settings to your K3. I was annoyed by this until I read Tom's FAQ here: http://va2fsq.com/faq/ Then the light turned on. There is no way to read settings from the K3 eq, so to externalize this, Tom is working around that limitation. Once you set them up in W4K3S you are golden. And it's a major bonus to changes those on the fly as I have described. BTW, I'm just a happy user of W4K3S if you are wondering... I have no reason to try and tout it other than I have been happy with the updates and support. Even if you don't use the spectrum display in W4K3S, based on my many year experience with LP-Bridge and NaP3, I still think it's well worth it on how it shares the K3 CAT data. It has been totally reliable too... Anyway, give it another try.... and play around with the multiple and dynamic UI settings for the eq in your K3.

I did not spend much time with it, but two things didn't seem right. Maybe I just didn't know what I was doing though. It seemed each time I started the program I lost the equalizer settings and had to reenter them. Also there was an issue about the resolution had to be set to 3 decimal places. I would rather have the resolution to two decimal places for CW and for SSB depending if I am running or just going up and down the band I want to have 1 or two decimal places. And again, maybe I just didn't know what I was doing. And since LP-Bridge handles all of my devices fine I didn't get too serious with Win4K3Suite. I have the P3 with external monitor so not too interested in another band scope. The one thing I can't seem to do with LP-Bridge is have the Acom 2000A track my K3's receive frequency in order to pretune. I have N4PY's program doing that in the background. Tell me I didn't do things correctly and that if I set up Win4K3Suite properly I can just start the program and it will start my other interface programs such as N1MM+, DXBase, AXETTY, like LP-Bride and be seamless. 73, N2TK, Tony -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net ] On Behalf Of M. George Sent: Wednesday, March 01, 2017 8:36 PM Cc: Elecraft Reflector > Subject: Re: [Elecraft] list submission, using ham radio deluxe and logic with k3 and a laptop with only com3 I used LP-Bridge for many years and never was satisfied with the reliability... plus the time it takes to create the virtual ports was always irritating to me. It is pretty good and the price sure is right however! I have switched to Win4K3Suite with com0com for the CAT sharing of the K3(s) and it has been rock solid. As others have mentioned, you can share the K3 CAT interface with up to 4 other applications and the lastest version of Win4K3Suite also adds 3 or 4 (off the top of my head) read only interfaces that you can use... i.e. like an SDA100 SteppIR controller or an Amplifier that will track the transceiver frequency. VSPE looks pretty good, but the license feed for the signed 64 bit version is ~$25 and that gets you half way to the cost of Win4K3Suite... Win4K3WSuite in and of itself is really nice. The more I use it, the more I like it... for example, pre defined RX EQ settings are so nice where you can just push a button and change the EQ settings on the K3 in a few seconds and if you are tweaking the EQ settings, you get to hear things live without having to leave the Config menu. Anyway, I'm really like the spectrum display to in combination with an LP-PAN2. It's become the replacement to NaP3. It's all together just a much more reliable solution than LP-Bridge and NaP3 IMHO. I can't live without my LP-PAN2 by the way... but now I no longer need to deal with LP-Bridge and Win4K3Suite starts right up with no delay where the com0com ports are created when Windows 10 starts up.

The first thing you need to know about an AGC response graph is the speed that the incoming signal was varied to produce the curve. In many cases, the input signal was steady state from a signal generator, set to a list of input levels, observing output levels, both recorded in Excel, and the resultant data pairs used to create a graph line. In this case the input variation speed is zero. This is a static analysis. If the input signal was **amplitude**-swept at audio rates, and together with the output signal, used to provide the X, Y values to drive an oscilloscope, then you have a dynamic analysis. At this point it is good to make a note of what test equipment you are familiar with that will provide an **amplitude**-swept, steady frequency signal. Inferences from a static AGC analysis and AGC induced IMD are apples and oranges. The second thing that bears heavily is the attack and decay speeds. Attack speeds are usually quick. If the attack and decay are **BOTH** quick, and that actual attack/decay is at an audio rate, then there is a case for distortion, because the variable gain can actually work at an audio rate. The question is whether the attack/decay cycle can continuously recur because the decay goes down as fast as the attack goes up, then intermod is indeed possible on a grand scale. However if the decay effectively holds the AGC gain level at a point set by the attack, delaying even as little as 100 milliseconds, then the AGC cannot create audio distortion products except very short low frequency distortion products only at AGC attacks. Since well before the significant AGC changes in firmware 4.7x (or whatever that one was), I have been running my slow AGC (CONFIG: AGC-S) at maximum fast, and my fast AGC (CONFIG: AGC-F) at maximum slow. In retrospect, that was probably why I never heard the stuff that a lot of people were complaining about. In contests I always use my max fast setting slow AGC, and back off the RF gain when I have primarily very loud signals in pile-ups to get the signals out of hardware AGC range, which has zero intelligent tweaks available. [And yes I have just about guaranteed pile-ups in contests with for-credit USA to USA QSO's, because of RBN spots which pick up everyone. Those are "spotting pile-ups" and assisted or unlimited class folks using point and click on the band map or control characters to move to the next unworked station.] My exception to using max fast setting slow AGC is when I'm trying to copy through lightning static, and need to hear weaker stations down in between the crashes. Then I use my max slow setting fast AGC. To summarize, in order for AGC to create audio distortion products strictly from the AGC, the AGC must be responding at an audio rate. Frankly, why would anyone want to set it that way escapes me. To Wayne, I would like to be able to set a minimum hold for fast AGC as well. That with a fast decay, would be better than what we have. Decay rate is something left over from analog days, when the way you decayed AGC was letting a capacitor discharge. 73, Guy K2AV On Fri, Mar 3, 2017 at 3:02 AM, David Gilbert wrote: > > I've had my K3 since 2008 or so, and over the years I've seen people > describe different forms of "mush".

I use my radio on a small lot and recently I added a short beverage antenna for low-bands receiving. My main activity is single-op contesting. Because of the interaction between the tx antennas and the beverage, on some bands I have the COR (carrier operated relay) activating when I use high power. I know the good solutions, but my point is different. As I have the COR activating only when the RX Ant input is selected, why doesn't the K3 firmware disable it when pushing the ptt? In fact, when I push the ptt I don't need the RX-ant part to be active, as I'm transmitting, and -at least in my setup- I have no other rigs/devices that need that input (I mean, no in-band receivers and so on). Instead of using external relays (ptt-activated) that cut out the rx input when I am transmitting, why the K3 firmware just doesn't disable the RX ant input on its own (and re-enables it if needed when releasing the ptt)? Maybe I'm missing something here, or that could be a nice improvement for a next firmware release.

One had about 75 mw on it during TX while beverage #2 had about 1 watt! This is enough power to cause damage to preamps, so I made two power limiters and now the inputs are clipped at about 0 dBm. All it took was two transformers and two diodes in a box. Do you know what the power level is on your beverage during transmit periods? Really high power levels could burn up the transformers. Disconnecting the antenna is a good idea too.

In the UK DE15HD is a bit of an obscure description, but I take it to mean a VGA EXTENSION cable (NOT A std. VGA cable) which has a male connector on one end and a female connector on the other end. I presume that these EXTENSION cables are wired pin to pin i.e. 1 to 1, 2 to 2, 3 to 3 etc., Does anyone know if this is the case? I realise that I would need a cable with all pins connected, then snip out the pins that should not be connected. I would happily buy another KPAK3AUX cable from Elecraft, but for an item which is readily available in the UK, it?s not really economical. 73, Alan.

On RTTY and other constant-envelope modes you can hear the RX antenna relay switching at the start of the tx and again when the tx ends. But on SSB it's really annoying as it continuously clicks (well, at least it protects the radio! HI). Just wondering why the RX antennas are not disconnected by the firmware while transmitting.

Beverages feed a DX Eng preamp before going the sub-RX. I don't do anything special to protect the radio, but it does occasionally protect itself. I also use the Beverages on 80, 40, and 30M, but TX antennas are much farther away (more than 100 ft). This is at 1.5 kW with a Ten Tec tube amp. BTW -- I just added a pair of VE3DO loops tuned for 160M and aimed to EU. Each loop is a rectangle 40 ft long and 10 ft vertical, with the bottom wire 2 ft off the ground and fed at the center. Details on OK1RR's website. The two loops are spaced 5/8 wavelength (350 ft). You probably don't have room for two loops, but you might fit one of them. 73, Jim K9YC On Sat,3/4/2017 2:11 PM, Fabio IZ4AFW / NZ1W wrote: > Hi Dave, > thanks for the suggestion. > I tried doing a quick measure using a cross-needle SWR meter today, > using the lowest setting. > On 40m the power appears to just deflect the needle, well below the 0.5W > mark.

I just discovered this problem with the current ARRL DX SSB contest. I can't set the MIC gain so I have 5 (+/-) bars on the ALC meter (with the last bar "wiggling"). It seems to be an all-or-nothing situation. There must be up be some setting I've fiddled with that changed everything, but I can't figure it out. The meter is either at "max" or zero...no gradual increase using the MIC gain knob. I'm using a CM-500 headset plugged into the rear panel MIC jack. The MIC SEL is set to rP.H bIAS (rP.L won't show any "bars" at all!). MIC+LIN is set to ON...makes no difference when set to OFF. I'm getting good audio reports, but I just don't feel comfortable without the "wiggling" last bar in the ALC "meter". Any ideas?

Message-ID: <000201d295bd$e9185810$bb490830$@verizon.net> Good Morning fellow Elecrafters, Thanks to the many Elecraft KX3 users' suggestions I now have my KX3 station back up and running with the PX3 AND the KXPA100 Amp. What did I do? I unplugged every cable I had going to the whole system (and actually took the time to make and apply labels on each and every cable) and dressed up all of the cables nicely. Now the rat's nest of cables is all neatly coiled and tied and sufficiently separated from the coaxial antenna cable. The main thing I worked on was to make sure that the RF-45 plug was seated (with a good solid "click" sound into the back of the amp). My thanks especially to my good friend Don Wilhelm, W3FPR, who has helped me throughout my whole Elecraft life. Thank you, Sir! On a personal note, I had had some chest pains last Sunday while walking our dog Ditzy, and, on Monday, my wife Kay drove me to the hospital ER. I stayed in the hospital all that day, that night, and all through Tuesday. I had lots of blood tests (every 3 hours) and had numerous important tests (such as an Echo Cardiogram, a stress test, and a CAT Scan) throughout the day on Tuesday. I was released after the hospital gurus were 80% sure that I hadn't had a heart attack. On Friday my own personal physician gave me a thorough examination and was able to interpret all of those hospital tests. He sent me home with some new prescriptions and the advice to take it easy and to stay in and near the house for a few days. I was planning on doing a little operating using my great KX3 for some R&R, but had run into the problems I have written about earlier. This morning all is well again with the radio, antenna, and the whole system.

I have owned Kenwood TS 830S, Yaesu FT1000D, Drake C line, Collins KWM-2A and multiple Collins S line radios. After being off the air for 10 years and disposing of all my previous gear I decided to get back on the air. Since I am relatively handy with a screw driver I ordered the K3S kit from Elecraft. While I am no longer the sharpest tack in the box and am definitely not a computer guru, I struggled initially with the K3S but after some familiarization I have decided that the guys at Elecraft not only made the best radio I have owned but that also made a radio that is intuitive. To me that is saying a whole lot. Using the radio is similar to finding the way to the bathroom, once you do it a couple of times you no longer get lost. Familiarization. Good job Elecraft and thanks for a radio that I will recommend to anyone.

After owning lots of very nice rigs (pics on my QRZ page), I finally decided I wanted to experience for myself what it is like to own the Flagship Elecraft rig. I will use one simple word to describe my experience so far: WOW! In the short time I have owned the K3S, my experience has been so pleasurable. My first thought as I was waiting for the rig to arrive was, "How much of a learning curve was I going to have before I would feel comfortable with the new rig?" Thanks to great advise I found here on the reflector and all over the internet, learning how to operate the rig has been a painless affair. The basic setting up of the K3S is easy and given some operating time, most functions are within a knob or a menu's reach and quickly learned. I decided to start out with the basic factory-built rig. Now I have the roofing filters I wanted to install and a internal tuner on order. I like the idea of learning about operating the K3S and seeing what features I would like and then adding those features as I go along. It was good for me to wait until now to get a K3S after owning some fine rigs from other manufacturers and getting to operate them in my shack. This has given me some good points of reference to compare and contrast with the K3S. I am primarily a CW operator and the Elecraft K3S has earned it's place at my operating position as a fine performer. Though it is not perfect (what ham rig is perfect?) it is a pleasure to operate on both CW and SSB.

FYI - I reloaded the K3S firmware. No change. On a whim, we connected the radio to the computer via a USB Hub (non powered). This seems to have addressed the problem. The USB port on the computer (older chipset) must not like the current FTDI adapter in the radio. This seems counter intuitive, but the HUB seems to facilitate the proper communications between radio and computer. We have cycled the radio and computer many times in various sequences.

If it were the firmware, we would have seen many reports of similar failure. What did you plug/unplug since it worked last? A firmware upgrade does not change settings in the K3. Do you have the Line-in and Line out cables reversed? The Signalink Line Out goes to the K3 Line In, and the K3 line out goes to the Signalink Line in. Connect the Signalink Line out to an audio amplifier and from your data mode application, do a "transmit" - do you hear audio tones? If not check your software and the Signalink. 73, Don W3FPR On 3/5/2017 3:04 PM, CAS wrote: > I have been using my K3 with a SignaLink USB for some time without > issue.

I always chalked this up to being able to hear audio from my headphones sitting on the left side of the desk here, but I'm getting a low audio out of primarily the left speaker still when spkr+ph is off. I'm going out of the speaker output on the K3s KIO3B into some high end speakers, but I can duplicate the issue with a pair of headphones too. So it's not the amplified speakers picking something stray up. The CONFIG AF GAIN is LO and when I switch between LO and HI, the output gets louder with the SPKR+PH off. The output is primarily on the left channel too? Scratching my head. A bad relay on the KIO3B? When I switch the SPKR+PH to ON, all is well for the left/right output on the output and of course the volume / AF level goes way up like it should. By the way, I have SPKRS set to 2 as expected.

One other tip - it is far easier (and better) to use the K3 Utility to perform the calibration. It handles everything in the right order and will perform the job quite well, handling things that would otherwise cause questions.

After one has a reasonable understanding of the concepts, the stituation that comes up now and then is wanting to change some of the AGC parameters in the K3. I don't know about others, but I tend to forget the direction of parameters such as AGC "slope". Do I want to increase or decrease the number to achieve my intended result? That is not about understanding the concepts, but simply about an arbitrary definition that can be equally "right" whether it is one way or the other. There are many other examples of K3 parameters that have names that don't fully describe what they do. Of course, the parameter names must be (too) short because of the display limitations. However, when one has a P3, that opens up a whole different world in terms of graphic displays. It seems to me that something like an AGC curve could be displayed graphically (as in your paper) right when the parameter is being changed. That way one would not have to worry about a detailed definition; just turn the knob and see the effect. The graph would be made extra helpful by the fact that the actual noise level is visible at the same time. No doubt other K3 parameters could become more user-friendly if treated in a similar way. 73, Erik K7TV From k2vco.vic at gmail.com Mon Mar 6 03:17:49 2017 From: k2vco.vic at gmail.com (Vic Rosenthal) Date: Mon, 6 Mar 2017 10:17:49 +0200 Subject: [Elecraft] A question on the P3 or actually the Tx Mon In-Reply-To: <11f1194c-6c65-c75d-1dc0-80029bc79f27@sonic.net> References: <47A220A2-0952-4019-9E45-81F5BEFF5C16@yahoo.com> <11f1194c-6c65-c75d-1dc0-80029bc79f27@sonic.net> Message-ID: <3E14CD8E-EC06-4E86-BB1A-152B0E14F2D5@gmail.com> This is one of my pet peeves with the W2 -- it does not have an option for delivered power.

As I seldom am in a position to "Run" stations, I have not been bothered by what has been referred to as "pileup mush," except perhaps when I switch briefly to VFO B to comb through a DX pileup. My main concern with AGC is to protect my ears, so I tend to use one of the nearly flat slope settings. BTW, I really like the AGC action in my KX2. I recently sent my K3 to Elecraft for installation of many procrastinated hardware upgrades, including a second receiver. From my reading of the manuals, I gather that I can adjust each receiver independently, and can use different AGC settings on each. Am I correct? If so, it seems like (for DX'ing purposes anyway) I might want vastly different AGC settings for my left and right ears. I am thinking I might want one set of AGC parameters for optimum reception of a weak DX station, and another set of parameters setup to listen to the howling hordes in the pileup. Surely others have done this (if it is indeed possible). How does this work out in practice?

There is no such indicator for the AGC parameters, indicating that those menu entries apply to both the main and the subRX. The AGC parameters *are* Tech mode entries, so you have to set TECH MD to on before you can see them. 73, Don W3FPR On 3/6/2017 8:24 AM, Chuck Guenther wrote: > I've been using my trusty K3 for years with a single receiver, and > frequently experiment with AGC THR and SLP settings for best DX > reception.

If you cannot achieve 3.5 watts output with a 13.8 volt power source, then change the resistors. Check the power level again after installing the KXB3080 option. If you will always operate the KX1 from batteries or a power source with a voltage lower than 13.8v, you can install the power mod resistors at the start. It is not good for the KX1 Low Pass Filter components to run it above 5 watts. 73, Don W3FPR On 3/6/2017 9:07 AM, Anthony de Maillet wrote: > Hi Gentlemen, > > I have a KX1 kit purchased here in the UK in February.

The problem is that the rear speaker output on the KIO3B has audio on it after turning SPKR+PH to 'no'. I can sit at the radio and copy CW for example from the speaker output when there should be NONE and the level is most pronounced from the left channel. Bill apparently tried to get some legs on this issue a year ago per his post. I have AFX off by the way, it's nothing to do with AFX either. I don't have the subRX on either. I'll make a video of the problem this evening. It's not like it's a low, low AF output from the rear speaker out (when the output should be off / zero), the output is real and it's the main receiver output.

Of course, that assumes the calibration device is more accurate than the P3. :=) The nominal calibration value is 500. The intent was to make it correspond to the same value as in a W2, but the match is not perfect. For one thing, the P3 uses a more-sophisticated algorithm to match the diode detector nonlinearity than the W2.

The AGC stage is designed to vary its gain depending on the input signal; stronger signals get less gain, and this has the effect of compressing the amplitude range. This is the desired response." I believe this paragraph and the accompanying graphic can be misleading to the unwary. AGC does not compress the range of signals, it simply lowers the gain through the receiver. The range (difference between) signals might well be 130 dB at the input but it better be 130 dB everywhere else in the receiver too. If lower level signals are driven into the internal noise level because of gain reduction, so be it; that should be the only reduction in range. Al continues: "But signals above this threshold will be acted on by the AGC. Even though in real life an S9 signal is 5 S-units stronger than an S4 signal, because of the AGC it will sound only 11.1 dB louder ? less than 2 S-units louder. This is because, reading from the above graph, an S4 (-103 dBm) signal produces -15.3 dBV of audio output and an S9 (-73 dBm) signal produces -4.2 dBV, a difference of 11.1 dB. A five S-unit difference has been reduced to a less-than-two S-unit difference." Some are going to read this and mistakenly believe that while receiving both an S9 signal and an S4 signal, AGC is going to reduce the ratio between them from 5 S-units to two S-units. Hence, I suspect that "mush" the proponents believe that AGC somehow magically reduces the amplitude of the stronger signal that activates the AGC but allows the weaker ones to have full gain, so that they "catch up" and become indistinguishable from the stronger one.

That's NOT what I meant. I meant that if you listen to ONE signal at a time, their apparent amplitudes do not reflect reality, because of the AGC. If BOTH signals are present in the passband at the same time, then my comments DO NOT apply. I was ONLY talking about hearing ONE signal AT A TIME. NONE of my discussion EVER presupposed more than ONE signal being received at a time. THANK YOU. :^) I am beginning to believe that it's impossible to shed any more light on this topic. It continues to be one of the most misunderstood areas of all, and I'm not sure if any effort can clear up the confusion without adding more confusion of its own. At least, I know I've failed!

My short beverage runs away from the tower, starting about 5 meters from it and going towards USA (NW). Unfortunately I don't have much more space to relocate the beverage farther away. My idea was to ask adding a menu option that automatically switches off the RX-ant input when the operator pushes the ptt, as usually the single-op doesn't need to keep it connected while transmitting. Of course it should also re-enable it at the end of the tx if needed. I know that an external relay is easy to use, but this could come for free when a new firmware is released.

Let me say it in a slightly different way. The AGC simply reduces the gain of the receiver - and it will respond mainly to the strongest signal in the passband. Actually it responds to the integral of all the signals in the passband, but if there is a single stronger one it will predominate. When the receiver gain is reduced, ALL the signals will be proportionally reduced in amplitude - including the weaker ones. This is often referred to as "AGC Pumping". 73, Don W3FPR On 3/6/2017 1:19 PM, Wes Stewart wrote: > In Al's very nicely done paper he has this paragraph: > > "The purpose of Automatic Gain Control (AGC) is to reduce the range > of the > signals seen by the sensitive stages in the receiver.

Yes, BUT -- there is distortion associated with AGC action, and that distortion is what is perceived as "mush." [Remember that the fundamental definition of distortion is "anything in the output that's not the input multiplied by a constant. Distortion can include time-variable gain, non-constant amplitude and phase response as a function of time or frequency, and amplitude non-linearity, variable time response. ALL of these distortions have the potential for confusing the ear-brain when trying to get intelligence from a signal, or providing aural satisfaction when listening to music. The K2 provides a great example. It sounds great and audio is easy to copy when listening to a SSB signal through the TX filter, but sounds awful and makes copy very difficult when the crystal filters are stagger tuned to provide narrower bandwidth. That's because the frequency response is pretty flat for the TX filter, but looks like a side view of the Rocky Mountains with the stagger tuned filters, and because every change in amplitude response is accompanied by non-constant phase response.] More important -- this "mush" problem is NOT a theoretical concept -- the problem has been experienced by hundreds of great CW operators in contests and DX pileups. Those operators have, by careful experimenting based on their understanding of how AGC works, and by listening to the results of tweaking AGC parameters, developed settings that SOLVE THE PROBLEM. Caps added for emphasis. In general, their solutions are quite similar, differing only in degree. This is NOT a problem for casual contesters or DXers, who either don't call CQ in contests or don't have a big enough station or a callsign that's rare enough in a given contest to generate a pileup. Most of the time I'm operating I fall into the first category, but occasionally the second. I've tried the recommendations of several top CW contesters, and I do agree that the result is making multiple callers easier for my brain to separate. 73, Jim K9YC From jim at audiosystemsgroup.com Mon Mar 6 15:04:58 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 6 Mar 2017 12:04:58 -0800 Subject: [Elecraft] [K3} AGC White Paper In-Reply-To: <24daabc9-9725-d112-2f2b-dd72f6c11e6c@gmail.com> References: <030601d2964b$66d144f0$3473ced0$@cox.net> <24daabc9-9725-d112-2f2b-dd72f6c11e6c@gmail.com> Message-ID: On Mon,3/6/2017 11:42 AM, Igor Sokolov wrote: > This is really a great idea wich is if ever implemented would make me > finally purchase P3. Igor, While it's a nice idea, it may or may not be possible to implement. BUT -- we're both pretty active contesters, and I wouldn't dream of working a contest without one. The SVGA card makes it even more useful -- the waterfall can be set to provide 2 minutes on screen, which really helps when trying to find a run frequency. You can look at the patterns to see which frequencies have someone running, and even when skip doesn't let you see the run station, you often see his callers. A waterfall tweaked for lots of averaging is great for finding weak signals on a band that is barely open. And a P3 is great for chasing down sources of RX noise. 73, Jim K9YC From k6dgw at foothill.net Mon Mar 6 15:13:22 2017 From: k6dgw at foothill.net (Fred Jensen) Date: Mon, 6 Mar 2017 12:13:22 -0800 Subject: [Elecraft] [K3} AGC White Paper In-Reply-To: <030601d2964b$66d144f0$3473ced0$@cox.net> References: <030601d2964b$66d144f0$3473ced0$@cox.net> Message-ID: <528e216e-ed16-e1b4-0a0f-27319c676c82@foothill.net> I think about it as follows: THR: The signal level at which AGC action begins. Lower number = lower signal level where AGC begins. SLP: Wayne is an EE and I'll bet he views SLP as the degree of gain compression in the AGC system. Thus, higher SLP values mean a higher amount of "compression" [and more flat] curve after threshold. I'm a math dude, not an EE, and I view "slope" as the first derivative of the AGC gain function ... which is unfortunately exactly backwards to the way it really works. I get around this by assuming "SLP" is a really weird acronym for COMPRESSION and not for SLOPE.

In truth, depending on the AGC *attack time constant* the AGC system responds to the *instantaneous peak voltage* of all signals in the passband. Even for two signals where one signal is *only* 10 dB stronger than the other, the *instantaneous peak voltage* can be as much as 20 dB greater than the stronger signal alone. With multiple signals, e.g. a large pile-up, and [relatively] slow attack times, the instantaneous peak voltage can drive the ADC into clipping before the AGC can react while with very fast attack and decay times AGC can "pump" the receiver gain at a syllabic rate and further "muddy" the recovered audio. Steady state (single signal, single tone) measurements can show the general AGC behavior but it is still an "art" to find the best combination of attack time, decay time, threshold, slope (gain reduction) above the threshold, "hold" times and *overall gain* to keep peak signal voltages below the ADC clipping point and simultaneously keeping the AGC response from "pumping" receiver gain in such a way as to generate IMD (mush). The key here is the *DYNAMIC* response of the AGC system. 73, ... Joe, W4TV On 3/6/2017 2:29 PM, Don Wilhelm wrote: > Wes is correct.

Below are the results MIC SEL was set to Line In to adjust volume - no effect so returned to mid-range setting of 30 CONFIG:LINE OUT was set at nor 10 - the default value - did not change this setting I verified that the Line In and Line Out cables from the SignaLink were in the proper locations and tested both external audio sources and sinks - all worked fine. I tested the K3 Headphone out - there was audio output. I fed the K3 Line Out to an audio mixer and verified that there was output, but it was low. I went back to the SignaLink and increased the volume using the front panel controls from what had been 30% full to 70% full for both TX and RX - I now had signal in and out. Note: The SignaLink and the radio were physically connected exactly the same before and after the firmware upgrade, the only difference was the firmware change. The 30% setting is what I had been using prior to the upgrade. Now I need to increase both the gain on the SignaLink and the audio output from the computer to get to the same output level from the radio as pre-upgrade so am wondering if the gain settings/cals have changed. I should note that the previous firmware was likely 4+ years old when I did the upgrade. Unfortunately, I did not either backup or note the previous versions.

I have stereo audio in the headphones AND the external speakers. When I change CONFIG: SPKR+PH = NO I still have low level audio coming from BOTH of the stereo speakers. Headphone volume is normal. The left speaker seems to be slightly louder than the right speaker. Adjusting the BALANCE control will alter the balance of the two speakers. There isn't any adjustment of the balance that doesn't produce some audio from one or both of the connected speakers. When there isn't a patch cord connected to SPKRS and the internal speaker is opeating there is NO audio coming from the internal speaker when CONFIG: SPKR+PH = NO. This is exactly what is expected and NOT what happens when external speakers are connected. Not owning an original K3 I've assumed this is just 'something I have to live with' with the K3s.

You shouldn't judge the KX2 based on that test. If you have the internal ATU (or some external ATU) connect a wire and a counterpoise. You'll have better results.

With ransomware a part of your threat model, you must also protect your backup from being encrypted. My own approach is to have 2 backup disks, one of which is offline and disconnected, and powered down at all times. Cloud backup systems may also have ways of protecting your backup. The real problem is that modern operating systems can't protect themselves or you. One way to help your OS is to never use an account with administrator privileges to browse the web or run other applications.

Unfortunately that was already set to PH.R SW-. Changing it to + definitely didn't mute the speakers! The issue we're seeing is the speakers are not completely muted. You can still hear audio coming out of the speakers, nowhere near as loud, but it's still there. Unlike the built in speaker which is completely muted under the same circumstances. You did prompt me to try a regular speaker in the SPKRS jack (non-amplified). Interestingly there is NO audio heard when SPKR+PH = YES. This leads me to believe there is 'some' audio at the jack, enough to be amplified. Why, that I can't answer, maybe something to do with input impedance of the amplified speakers? Anyway, just another data point in something that's not a big issue but makes for good discussion.

The KX3 is a nice rig and it performs very well. When you add the amplifier and PX3 you have a completely workable setup that has the added advantage of extreme portability. However, the K3s has a number of features and capabilities that don't come with the KX3. You have greater options for filters, dual receivers, digital modes, etc. The P3 has a larger screen, and it can connect to an external monitor. The KX3 by comparison has relatively weak audio and would benefit from either amplified speakers or headphones. I would say that if you are considering contesting, then the K3s is the way to go. IF all you want is casual use, the KX3 with amplifier is plenty of radio.

Many VGA cables include connectors without pin 9, obvious by visual inspection. Thinner "monitor" cables with ferrite beads on both ends usually do not have all 15 pins wired either.

After a friend's system was ransomed, I chose the most paranoid path I could afford: - Daily file syncs of data files, between the Win7 desktop and Linux laptop. This has the added advantage of keeping the laptop up to date in case of a surprise business trip. Having the syncing between two different systems provides an added degree of protection, because they're not accessible to each other via the network for most of each day, and the laptop is protected by gufw. I use Allway Sync to synchronize data files. - Daily file sync of data files between the desktop's working drive (SSD) and an external USB 5TB bulk HDD. The HDD is only connected to the desktop when it's needed. - Weekly data file sync to a portable backup drive. I also take this one on travel in case Bad Things Happen. Doing so has only paid off once, but having the data files backed up and available was a real life saver. - Periodic system images, about 4 weeks apart, to adifferent portable backup drive. Images for both the desktop and the Linux laptop. Making the image takes about two hours each time. I do something similar for my XYL's desktop and laptop systems, but not as often. 73, matt W6NIA On 3/7/2017 11:24 AM, Clay Autery wrote: > Yes, I have received phishing attempts via BOTH [Elecraft] and [Tower Talk] > > I recently billed 45 hours helping a client work through a ransom-ware > attack on their entire network that started with a simple email link. > > Cost them MOST of their data and a LOT of money.

It shouldn't affect the decoding. If the AGC time constant is too fast then, yes, it can cause distortion and degrade the decoding. But that should never happen in a properly-designed AGC system. AGC makes the decoder's job easier, not harder, because it reduces the dynamic range the decoder has to deal with.

If you're listening to a signal and it's too loud for your ears and you turn the audio gain down 10 dB, does that change the amplitude ratio of any signal you're listening to? No, it lowers everything by 10 dB. AGC is no different, it just operates at another location in the radio. IMHO, this thinking is the result of looking at too many ACG slope, threshold, and phase of the moon charts and assuming that bigger signals have their gain reduced more that smaller ones at the same instant in time.

Both are 12w radios so I added a KXPA100 which can be driven by either radio. I would lean toward the KXPA100 if I only had the KX3. If you later want a K3S you could get the K3S/10 and also use it with the KXPA100. That would be a little more expensive than buying a K3S/100, but allows you to run 100w with the KX3. I am setting up my KX3 + KXPA100 for mobile use where the smaller footprint of the KX3 works much better at the dash of the truck. I have no opinion on the PX3 as I have sw for panadaptor use with my LP-Pan and K3. PX3 would be nice for use without need of computer with the KX3.

Despite setting CONFIG:SPKR+PH to --, I still have no sound from the internal speaker. The rear panel speaker jack is working fine... when CONFIG:SPEAKERS is set to 2, then I get main in one channel and sub in the other. If I set it to 1, then both appear on the same speaker. FWIW, I am using a proper TRS mini plug to two RCA plugs, meant to drive two speakers. When I tested the mono output, I used a Y-adapter to re-combine the two channels back into a single RCA to plug into a speaker. But, I digress. It's the darned internal speaker that isn't working. Except, one time, it did. I was around back of the rig, unplugged the rear plug, and the sound stopped coming through the external speakers and poured out of the internal one. Except for that one time, never again. So, I have done the following several times... I have set CONFIG:SPKR+PH to -- (and back to +, and back to --...) I have unplugged and plugged back in the internal speaker connection. I have emailed support @ elecraft.com a couple of times, but all they could offer was CONFIG:SPKR+PH and the internal speaker connector. They did give me a step by step guide to doing CONFIG:SPKR+PH and I followed it precisely, down to saving the config file as a last step. Even did it twice...Still no luck, I'm afraid. So, I use headphones about 90% of the time, and there is an external speaker connected for when they are unplugged... is it a big deal? Well, no. More of an annoyance, really. Five or six hours of assembly, and every little glitch I found was a result of me not understanding how it worked...except for this little nagging bug, it worked PERFECT once I finished. Amazing, to me! However, when I keep reading posts about these speaker issues, I figured re-posting this might help someone track down whatever is the root cause. And, who knows, maybe that will help me, too. 73 de Chuck, WS1L -- =================== Chuck Chandler chandlerusm at gmail.com =================== From john.meade at freqelec.com Tue Mar 7 17:15:36 2017 From: john.meade at freqelec.com (John Meade W2XS) Date: Tue, 7 Mar 2017 15:15:36 -0700 (MST) Subject: [Elecraft] K3s Hearing low level rear speaker audio with SPKR+PH no and low AF set In-Reply-To: <1488920981735-7627716.post@n2.nabble.com> References: <2B4116D7-3C4C-40A4-BE80-7AFBB0DAF26C@widomaker.com> <1488920981735-7627716.post@n2.nabble.com> Message-ID: <1488924936788-7627731.post@n2.nabble.com> Maybe it's an impedance issue.

What we almost always see is that one or more indivudual list subscribers are hacked and their computers in turn send out these phishing emails to the list addresses in their email address books. I see these across the board on a regular basis from a wide range of lists and individual sources. The elecraft list does require the sender address to actually be subscribed with that address to post to the list. We see a wide range of spam, phishing etc. from non-list senders in our list spam folder each day. Note that is is quite easy for anyone to use any email address as their 'sender' address in an email, I can do it here in less than 60 seconds, so its not surprising some of these slip through from time to time. In general, do not ever click on links in an email. If you think an email requesting info is legitimate, independently go to the web site for the business in question (not the one the email points to..) and then log in normally and check out if there is are any notices etc. Let's close this thread now before it takes up more room than the initial spam that made it through. :-) 73, Eric /elecraft.com/ On 3/7/2017 10:52 AM, Mike Rhodes wrote: > > > RUN, don't walk the other way.

IF all you want is casual use, the KX3 with amplifier is plenty of radio. I generally agree with that advice. But there are other things that a K3 can provide that the KX3 cannot, like a real second RX with a separate input to do diversity RX. Switching from a digital mode to SSB or CW is far easier with the K3. The question you have to ask is "what sort of operating do I want to do?" The KX3 is clearly the choice for a ham who does general operating, portable operating, mobile operating, and operating from home. You want the 100W amp when you're mobile, and maybe at home. Also, don't consider ONLY the K3S -- a used K3 that comes up for sale here is a great option. I've chosen to hang on to my early s/n K3s and have simply added the new synth and the new transceiver board that gives me the two-stage preamp. That's at least 90% of the difference between a K3 and K3S, and at a significantly lower cost. 73, Jim K9YC From hlyingst at yahoo.com Tue Mar 7 17:57:03 2017 From: hlyingst at yahoo.com (Harry Yingst) Date: Tue, 7 Mar 2017 22:57:03 +0000 (UTC) Subject: [Elecraft] Augment KX3 or buy K3?

One thing we learned about DSP in pro audio is that dynamics processing burns a LOT processor cycles. DSP SIMULATES the behavior of analog circuitry, but depending on the code and the processor, the quality of the emulation can be varying degrees of ideal. ALSO -- those of us who have worked in broadcast audio know that dynamics processing can be a VERY complex business, especially when you're trying to do a lot of it, and even with a budget far larger than in a ham rig. Even in analog, it's tricky to do a LOT of gain change and still sound good. A handful of designers were good at it, and made a lot of money for themselves, or their employer, or both. And I'll repeat my previous observation that a signal path with gain that varies with time or with the signal amplitude is NOT a linear device, and non-linearity => distortion. 73, Jim K9YC On Tue,3/7/2017 1:53 PM, Wes Stewart wrote: > AGC adjusts the receiver gain, compared to the audio bits, rather > slowly and DOES NOT change the "dynamic range." > > If you're listening to a signal and it's too loud for your ears and > you turn the audio gain down 10 dB, does that change the amplitude > ratio of any signal you're listening to?

I also find it's performance pluses to be significant in crowded band conditions. I'll add two more considerations. Ergonomics: My K3 is just easier to use in the shack than my KX3. More dials, bigger buttons, easier to use in its position, etc. The tilted KX3 is just not so user friendly. Shack layout: Having a separate amplifier would mean more cables to fuss with. If I were in your position, I'd think about buying the K3s, the P3 (if a panadapter is important to you) and then -- if you use the KX3 only for things such as SOTA -- selling it and replacing it with the smaller KX2. Now that I have a KX2 I seldom use my KX3 (even though I have the PX3 as well). The "QRP-ness" of the KX2 makes it a fun rig and its performance seems right up there with the KX3. Only disadvantage -- unimportant to me -- is fewer bands. And I far prefer the KXPD2 to the KXPD3 -- again, likely a personal preference. Not all will agree, but that's what I'd do in your situation (sans financial considerations, of course!). 73, Phil W7OX On 3/7/17 2:40 PM, George Thornton wrote: > To amplify this answer, the dual-receive and filter options available only on the K3S are valuable tools for penetrating pileups.

Message-ID: <041101d2979c$4f5f3e60$ee1dbb20$@cox.net> I too have compared the K3 against a KX3 (with 100W) on field day. The K3 is much more practical, in that you can have everything cabled up for all modes of interest, so you can switch modes quickly. With the KX3, you have a bit of a rat's nest to begin with, and you end up unplugging the microphone to plug in your sound card, etc. Once you upgrade a K3 with the new synthesizer, there is very little difference in capability between the K3 and the K3S. I recently sold my KXPA100 and used the money toward a K3 in excellent condition (100 W, ATU, IF output options included; as were all the minor hardware changes recommended over the years) which cost $1600. After I paid for the synthesizer upgrade and a CW roofing filter, I had spent much less than what I might have spent on a new K3S. Sure, I didn't get the improved preamp for 6, 10 and 12 and a few other, rather unimportant improvements that come with the K3S. This tradeoff made good sense for me. It would have been even better if the used K3 had had more upgrades, such as the synthesizer upgrade, the preamp upgrade, optional roofing filters. Remember, all those options are easy to plug in, and bring the K3 very close to a K3S. It would have been less good if the used K3 had needed a lot of small hardware changes involving soldering to bring it up to date as a K3. 73, Erik K7TV From ve3iay at gmail.com Tue Mar 7 18:42:13 2017 From: ve3iay at gmail.com (Richard Ferch) Date: Tue, 7 Mar 2017 18:42:13 -0500 Subject: [Elecraft] [K3] AGC White Paper Message-ID: > AGC adjusts the receiver gain, compared to the audio bits, rather slowly and DOES NOT change the "dynamic range." Exactly. AGC changes the receiver's gain between two points in time, not between two signals arriving at the same time. I believe changing the AGC settings does improve the "mush" situation in CW, but the reasoning is more subtle than a simple picture based on dynamic range alone. Consider a situation where there are two CW signals, one at S8 sending mostly dits, and another weaker one at S7 sending mostly dahs. If the AGC threshold is well above the strength of either signal (or AGC is off), you will be able to tell when a dit from the stronger signal ends even if a simultaneous weaker dah is continuing, because of the change in signal level when the dit stops. In other words, you will hear the dits from the stronger signal riding in above the lower-volume-level dahs. Now suppose the AGC threshold is below both signals, say at S6, and the slope of the gain curve is flat (i.e. the SLP is set to its maximum value). For now, assume a perfectly instantaneous AGC decay time (super-fast AGC). Then regardless of whether one signal or both is/are currently "on", the AGC will immediately adjust the gain to clamp the signal strength to the S6 level. In other words, even after the stronger dit finishes, the weaker but longer-lasting dah will still be at the same perceived volume, and you won't be able to tell when the dit ended. Result: you just hear the combination of two signals at a constant volume, i.e. "mush". If there are only the two signals, when both are "off" the gain will increase, raising the perceived noise level, but that's not the "mush" problem, it's the "noisy receiver" problem. If there are a lot of signals at or above the threshold, then the "mush" would be more or less continuous. In the real world, the AGC time constant will affect this. If the decay time is long enough (as in slow AGC settings as used for SSB), you might hear the audio volume drop immediately after the end of a strong dit and then rise during a continuing weaker dah, whereas if the decay time is very short, you might hear the brief drop in volume only as a blip in an otherwise constant-level sound. But at first blush I would think this would be a secondary effect compared to the main effect of adjusting the AGC threshold to be above or below the level of the signals. As far as I can see, none of the above applies to RTTY, which is nominally a constant-amplitude signal. Whether the signal is above or below the AGC threshold, the ratio of the instantaneous mark and space signals will be the same (unless one of them is on the skirts of the filter bandpass). Even if there are two signals on the same frequency, the differences in relative strengths of mark and space from the two signals would not be affected by AGC, although the overall amplitude might be. I don't know enough about how RTTY decoders work to guess at whether a constant-level signal (aggressive AGC) vs. a time-varying signal level (no or weaker AGC) would have an effect on decoding, but the same reasoning that applies to CW "mush" does not appear to me to be relevant. 73, Rich VE3KI From frantz at pwpconsult.com Tue Mar 7 19:29:21 2017 From: frantz at pwpconsult.com (Bill Frantz) Date: Tue, 7 Mar 2017 16:29:21 -0800 Subject: [Elecraft] Augment KX3 or buy K3?

For me, the bigest advantage of the K3(S) over the KX3 it the ease of switching between modes. I like to turn on the radio and look at the signals in a band and then try to listen to them. That means switching between Data A, AFSK A, SSB and CW a lot. With the K3, I only have to turn VOX on in the data modes and off in SSB. (Please save the VOX setting by mode!) On the KX3, I have to swap plugs and changing settings. I have all the steps listed on a card which I carry with the radio, but it is by no means as smooth as with the K3. I do get benefit from tighter filtering on the K3 when trying to rise to the top of a pileup. something that the KX3's dual watch doesn't do. I always use the big screen attached to the P3/SVGA as my major way of finding out what the radio is doing, so I would miss that too. But in the end, the ease of mode switch is the most important. On the other hand, in Garth's situation, since money is limited, getting the PX3 will give a whole new way of seeing the band. The PX3 and the amp are probably the best way to go. 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | I like the farmers' market | Periwinkle (408)356-8506 | because I can get fruits and | 16345 Englewood Ave www.pwpconsult.com | vegetables without stickers. | Los Gatos, CA 95032 From hwhite1 at maine.rr.com Tue Mar 7 20:31:14 2017 From: hwhite1 at maine.rr.com (Harry White) Date: Tue, 7 Mar 2017 20:31:14 -0500 Subject: [Elecraft] Augment KX3 or buy K3?

David Wicks, G3YYD, is the author of 2Tone and Kok Chen, W7AY, is the author of CocoaModem. Anecdotally, my experience after 250,000+ RTTY QSOs over the past 15 years concurs that minimizing AGC action supports best decoder performance. If my ears, or widely varying signal levels, can't tolerate AGC Off, then I use AGC Slow, SLP=0 and THR=14 or higher. Note also the comments about receiver IF bandwidth of 500 Hz except in extreme cases. Even in big RTTY pileups such as I encounter sometimes in DX locations, Again, I've anecdotally found that 500 Hz decodes better most of the time. I seldom go lower. This also implies turning off the K3 Dual-Tone filter. Both of these points (no, or minimal, AGC and moderate IF BW) are not intuitive, especially for an experienced CW operator. Ed W0YK __________________________________________________________________ G3YYD, 0210: Actually with RTTY the AGC setting should be slow. The reason for this is the best decoders decode each tone separately and make use of the signal amplitude and measured noise over time. They compare the individual tone amplitudes with their amplitude over about one character time before and after the character being decoded. They then combine the tones together before the final decision is made based on their individual signal to noise ratio. Sudden changes to receiver gain will provide less than optimum performance as it will alter the amplitude relationship and noise over much less than 3 character times (about half a second). For those older decoders that use a FM demodulation system fast or slow AGC makes no difference so set the AGC time constant as you would for SSB rag chewing - slow. As for bandwidth do not set it below 350Hz as Chen W7AY indicated earlier this can cause distortion across the bandwidth by delaying some parts of a RTTY signal more than others. This blurs one bit of the RTTY signal into the adjacent bits. This is the signal causing QRM to itself. I personally tend to use 500Hz on my K3 and only reduce to 350Hz in extremis. The filters in a modern decoder are very narrow. 2Tone for instance uses a filter for each tone that are just 45.45Hz wide and at 90Hz wide have more attenuation than the receiver's dynamic range. Reducing RX bandwidth below 350Hz is for human hearing limitations not that of the decoder. 73 David G3YYD __________________________________________________________________ W7AY, 1015: If you are willing to manually ride the RF/IF gain controls, "AGC off" is best. As David G3YYD has pointed out, you need the "gains" of the Mark and Space tones to be perfectly equal. Under poor SNR but good propagation conditions, 0.5 dB of imbalance will cause noticeable harm in the error rates. Basically, you want the gains between the mark (M) and space (S) bits to be constant. The strength of the composite signal (M+S) need not be constant. Together with proper filters (narrow enough to avoid QRM while adding no intersymbol interference), slicing (deciding whether mark or space has arrived) is an equally important aspect of FSK demodulator design. You can easily make the case that the slicer becomes more important when conditions are poorer. The slicer decides whether the mark signal or the space signal is greater at each bit period. Good demodulators take care of slicer imbalances by the use of "automatic threshold correction" (ATC) circuits or software code. You can also use FM techniques to get around mark/space imbalance, but that creates more problems that it solves -- that is why good demodulators nowadays use two individual "AM" demodulators. It is always best to present to the demodulator with a signal that has as little possible tone imbalance so that the ATC has the least amount of work to do. This way, you minimize the problems that the demodulator has to overcome. Thus, you would rather have AGC that does not keep the amplitude perfectly constant, as long as the two tones have the same amplitudes. Remember, the key is to have no imbalance. The two tones must fluctuate by the same amount. Good A/D converters (sound cards) provide dozens of dB worth of dynamic range to handle fading. Just keep remembering that RTTY demodulation depends on SNR and not on signal strength. Receiver requirements are very different from voice or CW modes. The ATC circuit has to work really, really hard (and fails often) when the AGC is fast enough to be affected by the tone amplitudes fluctuating independently. The AGC time constant must therefore be much longer than a bit period. Even an AGC time constant that is around 176 ms (character period of RTTY) already pose problems. Thus "AGC off" is the best, and if you are not willing to constantly ride the RF gain control, the slowest AGC time constant possible is the next best choice. Use a A/D converter with good dynamic range, and let the demodulator designers handle the rest for you instead of depending on the receiver designers and their AGC circuits (few of them are designed with RTTY in mind). There really should be two channels from a receiver -- one that uses no AGC, and is fed to the demodulator. The other is a channel with AGC that goes to the human ears. That is how I embed an RTTY demodulator into my own SDR program. With floating point arithmetic, the channel that is fed to the demodulator has practically unlimited dynamic range. 73 Chen, W7AY ________________________________________________________________ G3YYD, 1223: I see Chen got into this one before me. Chen and I both design and make available RTTY decoders. The internal workings of those decoders for best performance requires that the AGC does not change the receiver gain abruptly and it stays reasonably constant over several character times. Fast AGC will cause problems with the automatic threshold "circuit" (software actually),w which can be avoided by using slow AGC. As Chen says manual gain control that is set and left is best of all but in something like a RTTY contest not practical as the human also wants to hear the signal at a reasonable level. So the compromise is slow AGC. Hang AGC can also work well if the parameters are set correctly. 73 David G3YYD From wp4cw at aol.com Tue Mar 7 22:47:38 2017 From: wp4cw at aol.com (Wp4cw) Date: Tue, 7 Mar 2017 20:47:38 -0700 (MST) Subject: [Elecraft] K3/ K3S filter for sale Message-ID: <1488944858661-7627747.post@n2.nabble.com> I have for sale a pulled INRAD 1 kHz filter.

I thought about the options for about 2 months and went for the KX3, PX3 & 100W linear and the ATU. I have not regretted my choice. Having a caravan and using just the KX3 I have never had any problems of running the caravan battery down even after two weeks with no 230volt supply to charge the battery. There are some very wise heads on this reflector who will add further comments to help you make a decision. 73 de Barry G4DBS On 07/03/2017 21:13, elecraft-request at mailman.qth.net wrote: > > Message: 20 > Date: Tue, 7 Mar 2017 20:54:42 +0000 > From: Gareth - M5KVK > To: "elecraft at mailman.qth.net" > Subject: [Elecraft] Augment KX3 or buy K3? > Message-ID: > > Content-Type: text/plain; charset=UTF-8 > > Hi all > I am in the fortunate position of having some money to spend upgrading my > station; however I'm torn between two options. > > I have a KX3 which I love and use a lot as a base station and also for > SOTA.

It does not have the necessary filtering to be useful in that environment. Forget CW pileups with the 7300. The comment on buttons is rather laughable when you mention the 7300, one knob and infinite menus even to just change the CW speed. 1200$ for a 7300 is best spent sitting in the bank. The KX3 blows it away. If you can pick up a 7300 for 750$ then go for it but understand it is not an Elecraft. You are buying a bells and whistles radio and not a contest grade by any means communication grade radio. As for the 7610, it is all promises and yet to be totally revealed. If it is even half the rig that people are saying it is, well, good stuff does not come cheap. Expect a 3500-4000 dollar price point. And if it breaks, forget having the rig faster than a 3 month turn around. Call up Elecraft and you get a guy who speaks the Kings English and knows the rig and most likely can tell you what needs to be replaced over the phone. Don't get me wrong, The 7300 is a nice package. It is a very beginner radio. It does a lot of stuff and is one of the easiest rigs to get computer control interfaced with. Especially, if you want to do psk modes then it is very nice and just by plugging in a USB cable, you are on the air. That and HRD and you are cooking. For a contest grade radio, no. For a beginner radio, it has many bells and whistles that are nice but filtering is not one of them, unfortunately, because their front end selectivity is weak. Right now I have seen many TS590s / SG for sale for under 1k. These radios are easily computer linked. Using a K1EL winkeyer and N1MM, what a great combination. I found one outstanding feature is their internal antenna tuner. It matches stuff that easily a 10:1 SWR mismatch and does not fold back the power after the match. I have personally used one on Field Day at least 2 times and they worked great for CW and SSB. Their menu is intuitive and easily addressed. For a beater radio, it is great. They have really good front ends for their price point and excellent selectivity. They run 100 watts off the line and recently QRZ had one for sale for $750. Now that is where I would spend my sheckles. If I were looking for a second rig and wanted less cabledom problems for the best radio and the least dollars, done deal. Does it compare to a K3S, not even marginally, but most people if you sat them down in front of a radio would know enough to know the difference. In the end, truth be told, most ops will never realize the capability of a KX3, KX2 or K3S and would be just as happy with any rig that would let them get on and talk to their good buddies, give weather reports or talk about hog farming on 160 at 11pm at night. Only when you are a discriminating op would you want or need better than a $700 to $1300 radio. I love my K3S and each time I run in a contest, I learn something new about some feature that I had not used before. On the other hand, I also own a Yeasu 450 and it is my test radio for antenna building and recently I put it in my truck as a mobile. It works great. going down the road running CW or a casual SSB QSO, it works great. It puts out 100 watts and works for me. For a contest grade radio, no so much. Its front end is easily over loaded in a pileup and it is selectivity is more than some what lacking. For casual operation, it is a great deal. The major downfall of the radio for casual operation and temp set ups is that the internal antenna tuner is severely lacking. It is limited to a 3 to 1 miss match. Knowing what is possible in radioland and having the money to buy what ever one wants with out so much as blinking, that is not me. Would I love to have a Flex 6700 with full second rx and Maestro interface to run SO2R...Oh Hell yes. Am I willing to invest $10,000 to get there...oh hell NO. What happens if is get a virus in the software that runs the radio? Im done. What happens if some part for the main box goes down, Im done. There is always a better mouse trap over the horizon. One can live well if one lives with in their means...providing they are not starving to death and have a warm place to sleep that is clean dry and disease free.

Like all radios you have to spend a bit of time learning how to drive it to full, it also depends if you have used one from the same stable before, though the touch interface of the 7300 is slightly different and I am not sure I prefer it to hard buttons, but clearly that is the way future radios are going, viz the pre-announced but unavailable IC-7610. I have the KX3 with PX3 and the IC-7300 and a recent, but used, hence less expensive than a K3, IC-7600 which was available at the right price, and I have to say that the IC-7300 has many things that make its ergonomics just great, in many ways better than the older IC-7600. I am in the U.K. and that colours my choices as Elecraft are doubly expensive here compared to the USA unfortunately. I paid more in the UK for my KX3 maxed out than a base K3 would cost in the USA, you get the picture. They are all great rigs, it all depends how much you expect to pay for a radio and what you want to do with it. No manufacturer is going to sell a top end contest radio for $1000, so whether it the big 3 from JA or Elecraft you have to spend the dollar to get the best. For the money the IC-7300 is excellent and a pointer to how Icom is going with their mid range , and I still prefer to have an IC-7300 than the money in the bank as it is such a good radio on 6m and 4m. If you post on an Elecraft forum asking about another manufacturer's product you will get a certain reaction, same if you you posted to an Icom forum about the Elecraft K3S. So always take anything you read pro or con with a punch of salt. Best advice is to actually try the radio you think that you want to buy, every 2nd ham you speak to on the air appears to have an IC-7300 so it shouldn't be hard to find one to try out. 73 from David GM4JJJ > On 8 Mar 2017, at 14:29, Morgan Bailey wrote: > > If you are even marginally serious about operating around other rigs (field > day), forget using the 7300.

The big performance difference with using a PC is that there are several decoders available, each with different strengths. These decoders typically have a lot of options that can be tweaked to optimize them for conditions. It's also possible to run multiple different decoders in parallel to see which one decodes the best at any moment. Having said that, I typically run whatever decoder is the default in whatever software I'm using, and seldom adjust the parameters. And, when the K3 is set to decode RTTY on its display, it generally does a remarkable job on its own, at least on strong signals. So, the built in stuff works well, but doesn't provide nearly the same flexibility as computer based software.

The decoder built into the K3 is pretty good, often as good or better than the software decoder. When used with a keyboard and P3/SVGA setup, it's pretty good for casual operation, and even for a DX pileup. My neighbor, W6GJB, uses that setup for casual operation and is quite happy with it. He also says that he thinks the decoder built into the KX3 is even better! There are several advantages though to using software decoders running on a computer attached to the audio stream. The major one is that you can choose decoder settings optimized for distortion produced by different kinds of propagation -- like selective fading, multi-path, and so on. The freeware MMTTY and 2Tone decoders are often used simultaneously to decode the same signal. When one decoder misses characters, the other often copies them fine. Contest logging programs WriteLog and N1MM Logger Plus make it easy to do this. Winwarbler does the same for non-contest operation. I use N1MM for contest logging and WinWarbler for non-contest operation. Many top RTTY contesters prefer WriteLog for RTTY. 73, Jim K9YC On Wed,3/8/2017 10:51 AM, Joe Subich, W4TV wrote: > >> For you experienced RTTY'ers, is the built-in capability considered >> on a par with using a separate sound card interface and separate RTTY >> PC software, > > Not even close!

I also ran cocoaModem using the KIO3B's "sound card"#. I used its crossed loop indicator for tuning and occasionally looked at its decode. The combination worked quite well. In summary, the internal decode works quite well. I haven't tried the internal encode, not having room on my desk for another keyboard and being terrible with a paddle. 73 Bill AE6JV * When using the internal K3 decoder through the programming interface, it is necessary to turn off the decode display on the P3's SVGA display. Some part of the Elecraft system runs out of CPU horsepower and the result is severe character loss on both the PC and on the SVGA. # My K3 has all the upgrade boards Elecraft has released.

Without trying to reproduce the receiver data tables, some representative numbers are: 3.5 MHz close in IMD (500 Hz bandwidth, 2 kHz spacing with preamp off) yielded a 3rd order intercept of +15 dBm and 2 tone dynamic range of 91dB. Same thing at 50 khz spacing was 28.5 dBm and 100 dB preamp off with numbers dropping to 9 dBm and 96 dB with preamp on. Mine seems pretty much like my KX3.

John KK9A - W4AAA Ed Muns w0yk said: Tue Mar 7 21:48:52 EST 2017 Below is a thread from 7 March 2016 about AGC usage with RTTY decoders. David Wicks, G3YYD, is the author of 2Tone and Kok Chen, W7AY, is the author of CocoaModem.

Ed W0YK __________________________________________________________________ G3YYD, 0210: Actually with RTTY the AGC setting should be slow. The reason for this is the best decoders decode each tone separately and make use of the signal amplitude and measured noise over time. They compare the individual tone amplitudes with their amplitude over about one character time before and after the character being decoded. They then combine the tones together before the final decision is made based on their individual signal to noise ratio. Sudden changes to receiver gain will provide less than optimum performance as it will alter the amplitude relationship and noise over much less than 3 character times (about half a second). For those older decoders that use a FM demodulation system fast or slow AGC makes no difference so set the AGC time constant as you would for SSB rag chewing - slow. As for bandwidth do not set it below 350Hz as Chen W7AY indicated earlier this can cause distortion across the bandwidth by delaying some parts of a RTTY signal more than others. This blurs one bit of the RTTY signal into the adjacent bits. This is the signal causing QRM to itself. I personally tend to use 500Hz on my K3 and only reduce to 350Hz in extremis. The filters in a modern decoder are very narrow. 2Tone for instance uses a filter for each tone that are just 45.45Hz wide and at 90Hz wide have more attenuation than the receiver's dynamic range. Reducing RX bandwidth below 350Hz is for human hearing limitations not that of the decoder. 73 David G3YYD __________________________________________________________________ W7AY, 1015: If you are willing to manually ride the RF/IF gain controls, "AGC off" is best. As David G3YYD has pointed out, you need the "gains" of the Mark and Space tones to be perfectly equal. Under poor SNR but good propagation conditions, 0.5 dB of imbalance will cause noticeable harm in the error rates. Basically, you want the gains between the mark (M) and space (S) bits to be constant. The strength of the composite signal (M+S) need not be constant. Together with proper filters (narrow enough to avoid QRM while adding no intersymbol interference), slicing (deciding whether mark or space has arrived) is an equally important aspect of FSK demodulator design. You can easily make the case that the slicer becomes more important when conditions are poorer. The slicer decides whether the mark signal or the space signal is greater at each bit period. Good demodulators take care of slicer imbalances by the use of "automatic threshold correction" (ATC) circuits or software code. You can also use FM techniques to get around mark/space imbalance, but that creates more problems that it solves -- that is why good demodulators nowadays use two individual "AM" demodulators. It is always best to present to the demodulator with a signal that has as little possible tone imbalance so that the ATC has the least amount of work to do. This way, you minimize the problems that the demodulator has to overcome. Thus, you would rather have AGC that does not keep the amplitude perfectly constant, as long as the two tones have the same amplitudes. Remember, the key is to have no imbalance. The two tones must fluctuate by the same amount. Good A/D converters (sound cards) provide dozens of dB worth of dynamic range to handle fading. Just keep remembering that RTTY demodulation depends on SNR and not on signal strength. Receiver requirements are very different from voice or CW modes. The ATC circuit has to work really, really hard (and fails often) when the AGC is fast enough to be affected by the tone amplitudes fluctuating independently. The AGC time constant must therefore be much longer than a bit period. Even an AGC time constant that is around 176 ms (character period of RTTY) already pose problems. Thus "AGC off" is the best, and if you are not willing to constantly ride the RF gain control, the slowest AGC time constant possible is the next best choice. Use a A/D converter with good dynamic range, and let the demodulator designers handle the rest for you instead of depending on the receiver designers and their AGC circuits (few of them are designed with RTTY in mind). There really should be two channels from a receiver -- one that uses no AGC, and is fed to the demodulator. The other is a channel with AGC that goes to the human ears. That is how I embed an RTTY demodulator into my own SDR program. With floating point arithmetic, the channel that is fed to the demodulator has practically unlimited dynamic range. 73 Chen, W7AY ________________________________________________________________ G3YYD, 1223: I see Chen got into this one before me. Chen and I both design and make available RTTY decoders. The internal workings of those decoders for best performance requires that the AGC does not change the receiver gain abruptly and it stays reasonably constant over several character times. Fast AGC will cause problems with the automatic threshold "circuit" (software actually),w which can be avoided by using slow AGC. As Chen says manual gain control that is set and left is best of all but in something like a RTTY contest not practical as the human also wants to hear the signal at a reasonable level. So the compromise is slow AGC. Hang AGC can also work well if the parameters are set correctly. 73 David G3YYD From andy.nehan at btinternet.com Wed Mar 8 17:52:38 2017 From: andy.nehan at btinternet.com (ANDY NEHAN) Date: Wed, 8 Mar 2017 22:52:38 +0000 (GMT) Subject: [Elecraft] K3- Separate AGC settings needed for: CW, SSB, RTTY Message-ID: <16711780.74966.1489013558663.JavaMail.defaultUser@defaultHost> I agree that an AGC which can be set by mode would be useful, but I suspect that the chaps have multiple requests for enhancements!

It will not relieve you of the "level tweaking" because the K3S CODEC is nothing more than a soundcard built into the K3S - the same audio level adjustments that would be used for another external (or internal) soundcard still have to be manipulated. To the computer, the K3S internal soundcard is "just another external (to the computer) soundcard". The terminology depends on whether you are looking at it from the computer side or the K3S side. 73, Don W3FPR On 3/8/2017 6:18 PM, Don Pomplun wrote: > TNX for all the helpful replies.

Just a computer soundcard and good quality audio cables so they do not pick up hum, buzz and noise. PTT is not required either, use VOX. Actually, the Signalink PTT is derived from the audio stream - so in effect, the Signalink has its own simplistic VOX which activates its PTT output. For those using the K3, get an external soundcard, even an inexpensive one and use the K3's VOX - it will perform better and with lower noise than the Signalink. For the K3S and a K3 that has the new KIO3B option installed, everything is the same, except the "external soundcard" (as seen by the computer application) is built into the K3/K3S and no audio cables are involved. 73, Don W3FPR On 3/8/2017 6:18 PM, Don Pomplun wrote: like the SignalLink USB. > Am I correct so far? > So then fig 10-14 (Fred's book) gives me the impression that with this > hookup, I can then run any RTTY software on the PC and the PC to K3S > interfacing is all taken care of, right?

RTTY decoding software like Chen's cocoaModem, David's 2-Tone and even Mori-san's MMTTY have extremely tight MARK/SPACE filtering capable of rejecting signals even 100 Hz away and nothing (not even tight IF filters) will reject an overlapping signal. 73, ...

Somewhat related story, I studied DSP at Rice University. When interviewing for a job (which I got), my future boss asked why on Earth I had taken an analog filters course. I told him that I knew how digital filters worked, and I wanted to know the analog side. I guess that was good enough for him, even though he had worked to make that course non-required when he was a professor. Also, my digital circuits prof was a working engineer at TI.

In general I have not found many bothersome birdies in the K3S, but there are some. If I don't have them, there is clearly something wrong with your radio which may warrant a return to Elecraft. BTW, I don't have much faith in firmware birdie removal. It certainly doesn't remove birdies in the panadapter display (LP-Pan and NaP3 in my case).

RX Performance Ranking? Message-ID: Rick and All, The Sherwood performance chart is strictly about RX, not TX!!! If you want TX info, you need to go elsewhere. That's what reviews like the ones in QST can give you. Rob has been doing this for a lot of years now, and on a strictly volunteer, no pay, basis. It has become somewhat "iconic", as a guide, but it's just another set of data that may, or may not, be helpful to you. It's not the only thing you need, or should rely on, in evaluating a purchase. you are right to be concerned about how clean a transmitter is, but there are regulatory requirements about that. If you don't meet those standards, you supposedly can't sell it!!! Besides, every rig is a QRP rig in part. The higher power rigs start out with a low power generation section, and step it up internally. So, a K3, or a KX3, both start out at QRP levels. If that low power section isn't proper, everything after that will be crap as well. So, everything in the chain needs to be operating within design limits. whether the step up is internal, or external, it still needs to be in compliance with requirements. You can hook a KX2 up to a KXPA100 up to a KPA500, and it sounds just fine--provided you don't get greedy! Most of the bad signals I hear are, I think, because someone is running things at "maximum'! There just seems to be a thirst for squeezing out the last watt, running the audio gain too high, or too much compression, whatever. Maybe the regulatory limits aren't severe enough, but if you don't push things too hard, I don't think you hear much of a problem. These days I don't hear that many rigs that sound bad unless there is some operator error involved. You used to hear a lot more of it that was not self imposed. Then again, some folks want a level of perfection that may not be all that realistic. Dave W7AQK From: Rick WA6NHC You're correct. But in fairness, those items should be based on a standard output power (not everyone wants QRP) and we already know that you're the only company concerned about those points and you're the clear winner. ;-) As I had said, it's more than numbers. There are many other factors involved in the 'test'. Sheer numbers only tell the science side of the operation; useless if you have to go through layers of menu to make a frequent adjustment. To me, knowing how clean a transmitter is should be on the list as well, what crud does it produce at a given output, in all modes. While some don't care they spread all over the band, I'd rather put the energy into a CLEAN signal to concentrate that one extra erg to make the contact. It's also about being a good neighbor; do unto others... ;-) Rick nhc From ed at w0yk.com Thu Mar 9 01:14:41 2017 From: ed at w0yk.com (Ed Muns) Date: Wed, 8 Mar 2017 22:14:41 -0800 Subject: [Elecraft] K3S's built-in RTTY In-Reply-To: <783ef942-b574-3c0a-f2d0-49d3877a121d@gmail.com> References: <441ddf31-7679-3920-9d58-dd3a7393488a@gmail.com><236901d29859$4886f0c0$d994d240$@comcast.net><50f2e291-b098-3e1d-06c9-81ca1c939c5e@gmail.com><2bdb2084-d1bf-c765-e8d9-4a67fd2d1a21@embarqmail.com><20664c30-7e8a-81ee-05a7-066694acf204@subich.com> <783ef942-b574-3c0a-f2d0-49d3877a121d@gmail.com> Message-ID: This RTTY system configuration is the worst one I can think of (sorry!). The RTTY receive will be great for you and transmit will be greatly compromised, for both you and your QSO partners. Once you have a PC/modem interfaced to the K3S for receive it is trivial to use it for transmit as well. The whole reason for the Elecraft built-in feature is for configurations where there is no PC and RTTY modem. The Elecraft CW-RTTY feature is a tremendous benefit for working one or, at most, a very few contacts without the complication of a PC and RTTY modem hardware or software. The caveat is few people can send good CW at 60 WPM so the copy by the QSO partner will be frustratingly slow. In a contest, for a few contacts, this feature can work well using the K3S CW/RTTY memories as long as the contest exchange is not unique, e.g., serial numbers. You can have one message with your call sign for answering CQing stations and second message with your exchange. You just press the K3S message buttons and the RTTY is sent out at the normal 60 wpm.

Once I got the cable placement as best I could, I even cut up sheets of carbon impregnated foam, put them inside of plastic sandwich bags, and stuffed the K3 with them to hopefully absorb some of the coupled energy between cables and various metal parts.

Some of the most expensive are really dirty on CW. http://k9yc.com/TXNoise.pdf Also look at http://k9yc.com/P3_Spectrum_Measurements.pdf which consists of measurements I've done myself of rigs that were made available to me. > Most of the bad signals I hear are, I think, because someone is > running things at "maximum'! Partly true, but some rigs are FAR dirtier than others. The link about concentrates on CW. Many popular rigs generate splatter in their output stage due to poor design of TX ALC. Using ALC between the rig and a power amp to set TX power is recipe for splatter and clicks. Mistuning a power amp, or failure to match an antenna to the power amp also causes splatter and clicks.

I also plan to clear all of the signal removal data and just rework it. I had the birdies cleaned up with the removal tool in most areas of the bands I operate. But since relocating the middle of last year into an ?antenna free? zone, I?ve been primarily using my KX3 with various temporary and stealth antennas. Had the K3 out the past couple of weeks to put a couple of updates in, and while tuning around to make sure everything was working again, really noticed them. Most likely I didn?t get the various cables back in the same place they were the last time I had the radio torn down, and that affected the previous removal settings. As someone suggested, it might be external signals, but they move backwards like a birdie and don?t show up on the KX3, so it isn?t likely. It didn?t help either that at least part of the time, I had no antenna connected, which made even the weak ones that normally get buried in band noise stick out ? :-) > > The firmware birdie removal took care of every bothersome birdie (and I am a stickler about weak signal performance) except for one that was still an S2 or so ... and that was in a portion of the band that I don't care much about. > > I did play around quite a bit with cable placement (see humorous note below) to prior to using the firmware fix, and didn't necessarily find the best arrangement to be the ones that Elecraft recommends.

If you are using soundcard digital modes, put the K3/K3S into DATA A mode, and adjust the soundcard output level to about 75%. Change the MIC SEL to LINE. You connect the soundcard line out (Spkr) to the K3 LINE IN and the soundcard line in to the K3 LINE OUT. If you are using the K3S internal soundcard, those cables are not used. Make certain there is nothing connected to the K3S LINE IN jack. Adjust the K3 LINE level ("MIC GAIN") to produce 4 bars solid with the 5th bar flashing on the ALC meter while your digital mode application is 'transmitting'. You can put the K3 into TX TEST for that adjustment so you do not emit any RF. If you are doing RTTY, use the AFSK A data submode, it defaults to LSB. DATA A defaults to USB. The major problem with folks starting out in digital modes is not with the radio, but with the digital mode application. It requires setup, selection of the COM port, selection of the right soundcard, the correct rig, and other settings. So refer to the instructions for whatever software you are using. If those instructions tell you to set the radio's power to full and use the audio level to adjust the power output, ignore that (and similar internet advice) - that does not work well with Elecraft gear, use the information given above to set the audio level and set the desired power with the power knob. 73, Don W3FPR On 3/9/2017 9:13 AM, Don Pomplun wrote: > Thanx for all the good points raised for this RTTY-wannabee, morphing > from CW.

Message-ID: Four months ago or so I sold my KX3/KXPA100 combination to purchase a used K3/100. There were a couple of factors. First of all, I had used my KX3 kit for NPOTA extensively, and I was done with that operation. Second, I had purchased an IC-706Mk2G and installed it mobile, permanently. Third, I wanted to install various accessories to operate contests that simply were not compatible with the KX3. I wanted to use N1MM+ software to run FSK RTTY. I wanted to be able to swap between digital and phone operation without having to unplug and re-plug. I wanted to use a MicroHam microKeyer, which wasn't compatible with the KX3. Finally, I wanted a smaller desktop package for home station operation and a cleaner permanent install. I also didn't want to daisy chain amplifiers to go > 100w (KX3 to KXPA100 to QRO amp). In short, my operating style changed and thus my equipment did to. The fact is that there are some accessories and software which are just not compatible with the KX3. And while it may be possible rig up something and 'make it work', I'd rather just use gear that works as intended.

I then tried it with my KX3 and to my surprise the SWR was showing high at the KX3. The filter alone attached to a dummy load shows a near perfect 52 ohms so the problem isn't on that end of the chain. If I use an inexpensive littte 5 watt 40 m QRP CW rig to drive the amp everything seems perfect with nearly 100 watts out of the amp.Should I assume that my idea to recycle an old CB amp was just a bad idea and cut my losses by throwing it away?

The K3 puts out band data in several forms on the AUX connector. Have you looked in the K3 manual? It's detailed there, and you can download the manual for the AS-419. Have you done that? You'll need a suitably wired cable between the AUX port and the AS-419. 73, Jim K9YC On Thu,3/9/2017 12:00 PM, NOEL POULIN wrote: > I would like to know is anybody in this group using the AS-419 > bandpassfilter system with the K3? > I was told it was possible to hook the system to the K3 for automatic > band change, without any band decoder??

Very nice design and good build. I would like to use this radio for ALE, which requires cross-band scanning. This mode is used only for initial detection. If I use the KX3 as is, when changing bands I can clearly hear relays switching, which I think is in the BPF circuit (please correct me if I?m wrong). Looking at the schematic it appears the BPF can be bypassed by asserting the BPF_BYPASS signal, but it isn?t clear from the user manual or CAT programming manual what mode in the KX3 achieves this effect. Any ideas how to get the KX3 to bypass the BPFs?

Of course the design goal for the KX2 was to pack as many bands, modes, and features into the smallest possible size, not to break records on RX measurements. Nonetheless, I'd expect the KX2 to come in somewhere in the top 20 or so on Rob's list. We'll see. 73, Wayne N6KR On Mar 9, 2017, at 2:47 PM, Chris Tate - N6WM wrote: > Thanks Gus this will be interesting.

I use it in conjunction with a 72 watt GE solar panel, 110 Ah AGM battery, ProStar charge controller, N8XJK Boost Regulator, and a KI0BK Low Loss PowerGate. All cables have been fitted with multiple mix 31 ferrite dounts with multiple wraps - I?ve got pretty much NO RF hash on any of the HF bands on the K3 or my KX3. All the above power equipment feeds into a Rig Runner 4008. Anderson PowerPole connectors connect to as short as possible #12 cable to several devices: K3, P3, KX3, PX3, KXPA100, and a home brew W6PQL 2 meter all mode amp. Haven?t had any issues with the above configuration. Until today, when I happened to punch the K3 DISP button, changing it from reading my VFO B frequency to the other various bits of information. One of them was the rig voltage. Sitting there on 17 meters in CW mode receive it was showing a nice 13.8V. Cool. I hit the key and - wait a minute?? it dropped way down to 12.4v. Huh - not so cool. My first thought was that the Boost Regulator was not doing it?s job. But I decided to start trouble shooring at ground zero - the MFJ 4245. I disconnected it from the Power Gate and ran it directly to the K3. Key up = 13.8V. Key down = 12.0V. Yikes! I think (IMHO) calling this poor regulation (15%) would be a gross understatement. Am I wrong for expecting a desk power supply to do better than this? I had purchased this 4245 years ago because the price was right AND that it can run on 117 or 220 volts. At one time I had been contemplating a move to the Philippines and a 220v supply would be needed. By the way, nothing else running here in the shack other than a computer which was in sleep mode anyway, so line voltage sag likely is not the issue. So, if this this a common problem with the MFJ stuff, what other 25+ amp supplies are folks using with their K3?s that have better regulation than 15%?

If you see a substantial voltage sag during transmit there, you can blame the power supply. But if the voltage stays close to constant, the problem is voltage drop in the power cabling. The RigRunner will contribute some drop due to the extra contact points and even #12 or #10 wire has some resistance. If the power supply is good, run a power cable direct from the power supply to the K3 and run another power cable to the rigrunner. Run the accessories in the shack from the rigrunner. 73, Don W3FPR On 3/9/2017 8:09 PM, James Bennett wrote: > Hi All - > > Haven?t had any issues with the above configuration.

Other than power supply issues, it is usually one of three things: 1. Intending to use the BAND button, one holds down the right MODE button by mistake, putting the K3 into TX TEST mode. The "TX" icon flashes. But, since you reported that the TUNE button flashes "0 watts" instead of flashing "TX TEST", it's probably something else in this case. 2. CONFIG:TX INH is set to LO=Inh (visible only when CONFIG:TECH MD is ON). CONFIG:TX INH should be OFF unless you're using a lockout circuit that depends on the inhibit line. A "floating" pin 10 on the ACC port can cause TX to be intermittently inhibited when CONFIG:TX INH is set to LO=INh. When TX is inhibited, the K3 will display "0 Watts" when you press the TUNE button. The "TX" indicator also flashes when the rig is inhibited, similar to TX TEST mode. 3. The most likely cause, which I've seen many times, is that the jumper board connecting the subreceiver to the main board in the back left side of the K3 has partially pulled out. This happens almost every time a K3 is subject to any kind of strong mechanical stress, such as transport in checked luggage. Make sure the SubRx is firmly seated and the problem should disappear. If you don't have a SubRx, there's still a jumper board that must be in place in the same spot. 73, Bob, N6TV On Thu, Mar 9, 2017 at 6:38 AM, Dennis wrote: > First thing I did- and the first thing I do whenever I have any funny > happen- is to cycle power.

To do my testing I had run the 4545 directly to the K3 and not through the Rig Runner. However, to do that I had simply hooked the cable from the 4245 that used to go to the Rig Runner into the end of the cable going to the K3, basically taking the Rig Runner, Power Gate, and Boost Regulator out of the picture. This gave me two cables, total of about 10 feet, with three APP connectors. Thus the connection went from the 4245 through a five foot cable and some ferrite donuts into another five foot cable to the back of the K3. The voltage dropped to 12.5 on the K3 meter. With some work, I pulled the cable out of the K3 and connected the 4245 cable with the ferrites directly into the K3. With this combination (only ONE cable and Power Poles at the K3 end) the voltage dropped from 13.9 to 13.1. This means that a second five foot length of cable and two APP?s caused a loss of .6 volts. So, what does all this mean? Since I am not using wimpy, skinny wire I have to conclude that perhaps the APP?s might be the cause of some of this voltage drop. With the original configuration I had using the AGM battery, Power Gate, Boost Regulator, and Rig Runner, there are a bunch of APP?s in the circuit, in addition to several feet of wire. I ?could? simply connect the 4245 directly to the K3 and settle for a drop of .8 volts (13.9 to 13.1), but that kinda defeats the purpose of having a solar / battery backup system and a power distribution system. I thought this issue would be solved by replacing the MFJ PS with something else, but it is looking a LOT more complex at this point. Crap - what is one supposed to do?

To do my testing I had run the 4545 directly to the K3 and not through the Rig Runner. However, to do that I had simply hooked the cable from the 4245 that used to go to the Rig Runner into the end of the cable going to the K3, basically taking the Rig Runner, Power Gate, and Boost Regulator out of the picture. This gave me two cables, total of about 10 feet, with three APP connectors. Thus the connection went from the 4245 through a five foot cable and some ferrite donuts into another five foot cable to the back of the K3. The voltage dropped to 12.5 on the K3 meter. With some work, I pulled the cable out of the K3 and connected the 4245 cable with the ferrites directly into the K3. With this combination (only ONE cable and Power Poles at the K3 end) the voltage dropped from 13.9 to 13.1. This means that a second five foot length of cable and two APP?s caused a loss of .6 volts. So, what does all this mean? Since I am not using wimpy, skinny wire I have to conclude that perhaps the APP?s might be the cause of some of this voltage drop. With the original configuration I had using the AGM battery, Power Gate, Boost Regulator, and Rig Runner, there are a bunch of APP?s in the circuit, in addition to several feet of wire. I ?could? simply connect the 4245 directly to the K3 and settle for a drop of .8 volts (13.9 to 13.1), but that kinda defeats the purpose of having a solar / battery backup system and a power distribution system. I thought this issue would be solved by replacing the MFJ PS with something else, but it is looking a LOT more complex at this point. Crap - what is one supposed to do?

I think I may have found one of the culprits in the system - oxidation. I put everything back together the way it was to begin with so I could switch back and forth between the K3 and KX3 power displays. I have a KXPA100 behind the KX3 so the load on the MFJ 4245 should be about the same with either one transmitting 100 watts and the other one receiving. What I see now is 13.9 volts on receive and 13.0 - 13.1 during transmit. Waayyyyy better than the drop to 12.0 I saw yesterday! I might get ambitious and ?upgrade? the cables from #12 to #10 and ensure that the APP contacts used are the 30 or 45 amp versions. Will also look into a re-design of the Boost Regulator?s position in the power system. RIght now it supplies boosted power to the Rig Runner. I think it?ll be an easy matter to swap some cabling around and have the output of the Power Gate go to the Rig Runner and have the Boost Regulator tie into the Rig Runner, delivering it?s output directly to the KX3, K3, and KXPA100. I believe this is one of the suggestions made by W3FPR. I?m pretty sure my desk lamp and the PX3 won?t mind only having 12.8 v instead of 13.9! :-) 73, Jim Jim Bennett / W6JHB Folsom, CA From kf0ur at radins.us Fri Mar 10 14:01:25 2017 From: kf0ur at radins.us (Shel KF0UR) Date: Fri, 10 Mar 2017 12:01:25 -0700 Subject: [Elecraft] K3S's built-in RTTY Message-ID: <001401d299d0$b7c453b0$274cfb10$@radins.us> Hi Don, If you're not using a PC, another option you have is to use the QRPworks K-Board.

Message-ID: <2C812AC1BBA3469BA83CD11ED178D18C@LAPTOPEPVQLR1I> Hi All, I'd be inclined to think the KX2 measurements won't knock your socks off. Unlike the KX3, which was designed to be a close competitor to K3 performance (a K3 in a smaller package), the KX2 is more a pared down version of the KX3, and some of that paring down probably affected the specs somewhat. I don't think this paring down process was allowed to noticeably degrade performance. I can tell you , though, that it is very hard to notice any significant difference. It has somewhat different architecture, but is an excellent performer. This sort of proves to me that being "top tier" on Sherwood's stats is nice to talk about, but not necessarily critical. That's why so many owners of older rigs have a hard time "hearing" the benefit of what newer designs purport to offer. Wayne says he guesses the KX2 might rank somewhere in the top 20. If so, that's pretty darned good!!! I'd also be inclined to bet that Wayne already knows about where it will fall! I just hope that, when the numbers do come out, we don't go through an ad nauseam exchange about some spec being a big problem or a serious disappointment. A lot of these differences are only determinable in a lab! On the other hand, if something does seem to be a real problem, I'd also bet it can be fixed!

RX Performance Ranking? Hi All, I'd be inclined to think the KX2 measurements won't knock your socks off. Unlike the KX3, which was designed to be a close competitor to K3 performance (a K3 in a smaller package), the KX2 is more a pared down version of the KX3, and some of that paring down probably affected the specs somewhat. I don't think this paring down process was allowed to noticeably degrade performance. I can tell you , though, that it is very hard to notice any significant difference. It has somewhat different architecture, but is an excellent performer. This sort of proves to me that being "top tier" on Sherwood's stats is nice to talk about, but not necessarily critical. That's why so many owners of older rigs have a hard time "hearing" the benefit of what newer designs purport to offer. Wayne says he guesses the KX2 might rank somewhere in the top 20. If so, that's pretty darned good!!! I'd also be inclined to bet that Wayne already knows about where it will fall! I just hope that, when the numbers do come out, we don't go through an ad nauseam exchange about some spec being a big problem or a serious disappointment. A lot of these differences are only determinable in a lab! On the other hand, if something does seem to be a real problem, I'd also bet it can be fixed!

Has anyone ever tried using unseparated ribbon cable counterpoises? ?The materials are on order and I'm sort of anxious to know. Obviously, this is a compromise antenna and I'm shooting to design a package for maximum installation speed vs. maximum efficiency.

Yeah I know the bypass is not ideal (garbage, etc.), but for ALE scanning it would be better than hammering on the relays. It is possible to select the bypass of the BPFs, as the hardware was clearly designed to support this. But the docs don?t explain how to get this to happen. I would greatly appreciate if anyone with knowledge of the KX3 could shed some light on what mode the software needs to be in to get the BPF bypass to happen.

Yes, I already have a 67 foot doublet fed with window line as well as ?simple wires and counterpoises in line with page 10 of the KXAT1 manual. ?They work just fine. ?No argument there. But I stumbled upon this "linear loaded" vertical antenna and thought I might try it. It's is a 20 foot piece of 300 ohm TV line with the conductors twisted and soldered together at the top and taped to a twenty foot crappie pole. ?At the bottom, for working 20 and 30 meters, both of the conductors are connected to the red BNC terminal on the KX1 making the the radiator just a "fat" 20 foot wire. ?For working 40 meters the bottom conductors are separated and one goes to the red BNC terminal and the other just hangs loose making it a 40 foot antenna. ?The write-up I found states, "On 40m the folded wire creates a linear loading effect due to the capacitive coupling between the two wires (note that currents are not equal and opposite so there is no cancellation of signal as you might initially think). This added capacitance allows the wire to be resonated on 40m by the internal tuner in the K1, KX1 or also by the Elecraft T1." The fellow who offered this antenna idea said that he had been using it successfully for quite awhile. Adding the BL2 is my idea because it will be part of the solution for making the bottom connections. ?My intent is to come up with a "decent" portable antenna that I can erect anywhere in just one minute. ?I want to come up with some creative way to make all the pieces work together effortlessly, rapidly and reliably, including dealing with the crappie pole. ? My dream is to drop the crappie pole into a homemade holder on my camp chair, push up the pole with the antenna following, walk the roll of ribbon cable out in a straight line, go back to the chair, sit down, turn on the KX1 and start operating! ?It's my springtime project.... I ordered a 100 foot role of ribbon cable so I can do a little experimenting with opening up the ends.

And, sometimes I would call CQ on the KX1 and work some stations and other times I would use the KX3. There are obvious physical differences between the KX3 and the KX1, I do not mean to compare them feature by feature. But, I don?t remember noticing any real difference in performance other than the obvious differences between the two rigs. I could work stations just as well with either. One of the obvious differences is that sometimes I would run more than 5 watts with the KX3 but limited to the lesser power out of the KX1 which I think is usually under 4 watts, maybe under 3. Of course, if I had to pull out a single CW station from a pile up or crowded band, I would use some of those KX3 features that the KX1 does not have. My KX2 is on order but I am looking forward to operating with it. I suppose that what I am saying is that in most of my own personal operations with QRP rigs, I don?t rely on a lot of those performance features that separate the top 5-7 from the top 20 of the Sherwood Eng.

Later I would like also to connect a band decoder on the same radio to switch coaxial stubs. I wonder if the K3s can handle more than one device connected to the Band Data signals. I suppose that Elecraft band output is probably designed to drive one decoder and this decoder is designed with current maximums for each port. I would appreciate comments and good tips about that fact...

Having wires of different lengths in close proximity means that the RF field will tend to act as though the conductor simply changes its thickness rather than being two conductors of different lengths. The old "rule of thumb" in the ARRL books was to be sure the last "several feet" of each wire is well separated from the others. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Don Wilhelm Sent: Friday, March 10, 2017 6:45 PM To: stan levandowski; Elecraft at mailman.qth.net Subject: Re: [Elecraft] (OT) - portable radial idea?

Thanks to some info from Lyle KK7P and Bob N6TV as to how things were wired up I was prepared to trace this and that... O'scope was ready... Turned out to be a loose wire where the internal speaker lead connects to the speaker lugs. I was all wrapped around the axle on CONFIG settings and worried that a multi-pin connector might not have been seated properly... turned out to be a simple problem. The solder lug on the speaker itself looks to be well soldered, but there is what looks like a crimp in that conductor just a bit upstream. My bet is there is a break in the wire inside the insulator there. For now, some electrical tape is holding the wire tight against the speaker so it can't move around. I'll email support and request a replacement.

Message-ID: <60885A4E-FA4F-418E-9465-2D87964732EF@magma.ca> Stan : Unless the ?radials? are to be elevated a few feet above the ground there is really nothing to be gained by trying to cut them for resonance on each band. If they are laid on the ground they will be detuned and the legnth will be all off anyway. The rule of thumb that I used is to make the radials at least an 1/8 wave for the lowest band, so in this case it would 16 feet long. I take a 20 foot length of computer ribbon cable (5 or 6 wire) and unzip it for all but the last 4 feet. Then on the unzipped end I strip and tin each of the wires and then attach them all to a banana plug. Having the last few feet of cable still zipped makes routing the ?radials? away from the rig and off of a picnic table much more convenient. To make storage and re-deployment simpler I pull the loose ends of the wires parallel and then I attach an IKEA bag clip on the end then I can roll the whole thing up, tie it with a velcro tie and put it into a zip-top sandwich bag. . It keeps the wires from getting tangled. Why 5 radials ??? I have found from experience that 5 or 6 is about the limit of my patience for deployment. I have a few sets so if I am not in a rush I can use more. This is easy to do with a Pomona banana jack to BNC adaptor as both the red and black terminals will each accept two banana plugs.

Have just downloaded the KX3 Utility program and can?t get it to work. It consistently refuses to talk to the radio. ?KX3 is not responding? is what I get. I?m (mostly) on a Mac. I?ve downloaded and installed the correct USB-to-serial driver. That shows up properly (as "usbserial-AL030VX?) under the Port tab. Interestingly, when I click the ?Test Communications? button I usually get ?KX3 is not responding.? Consistent with that, going to the Firmware tab the MCU and DSP entries under ?Installed in KX3? usually show as ??? because the program is not able to determine what versions are currently in the radio. But occasionally that ?Test Communications? button will return ?KX3 MCU revision 02.38. RS-232 speed 38400 bps.? And then going to the Firmware tab will show ?02.38? as the MCU version. In those instances, at least briefly, the radio has communicated with the program. Alas, every attempt to update firmware has resulted in a ?KX3 is not responding? message under the Activity Log. I?m using the KXUSB cable that shipped with the radio. I originally tried using the KX3 Utility on a Mac running 10.9. Didn?t work. I then tried it on a Mac running 10.10. Didn?t work. I then tried it on a Windows machine, running Windows 7 (with the appropriate Windows USB-to-serial driver). Didn?t work. Thinking maybe it was because of my slightly dated OS versions, I updated one of my machines to Mac 10.12 - the most current version. Still no joy. I?ve tried different baud rates on the radio side (noting that there?s no place I see within the KX3 Utility to set that rate). No difference. I?m fairly sure the KXUSB cable is okay, as I am running MacLoggerDX as my logging program. That program is talking to my KX3, using that very same KXUSB cable (and the same ?usbserial-AL030VX? usb-to-serial driver). I?m pretty computer literate. I don?t think it?s me. I?ve turned on ?Advanced Mode? and ?Verbose Logging? - not a lot of extra illumination. And I?ll give the good folks at Elecraft a ring on Monday if I don?t have an answer by then. But in the event I?ve missed something (meaning, it is me!) thought I?d first throw this out to you good folks.

Check for what you may need and how to install it. (2) The upgrades to install the new K3S upgrade boards. The big win here is the KSYN3A board. It will improve your receive and fast CW break in. The KXV3B board adds a second preamp for 12, 10, and 6 meters. The KIO3B 3-board set installs an internal "sound card" in the K3 for computer interface of digital modes. It also replaces the RS-232 connection with a USB connection. It is quite easy to install all three upgrade in a K3. Doing them one at a time will be less confusing, but if you have a good idea of how things in the K3 are connected together it is possible to install them all at once.

To avoid that, loosen the screws almost all the way but not quite out of their threads. Then tilt the board toward the rear and push the lockwashers as far onto the screws as possible. Then completely unscrew the remaining threads. Grasp the board (with the screws still through it) and pull straight upward. For all the other steps of installing the options, follow the instructions. 73, Don W3FPR On 3/11/2017 5:57 PM, gt-i at gmx.net wrote: > Hello list, > > I've purchased a used K3 S/N in the 3ks, and plan to apply some of the > K3S upgrade options. > Any experiences, hints or do's and don'ts to tell for me? > I'm using the K3 mainly for HF contesting, VHF with an external > transverter and some DX chasing. > tu es 73 > Gernot, DF5RF > > ______________________________________________________________ > 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 donwilh at embarqmail.com > From doug at k0dxv.com Sat Mar 11 22:36:55 2017 From: doug at k0dxv.com (Doug Person) Date: Sat, 11 Mar 2017 20:36:55 -0700 Subject: [Elecraft] K3 upgrade to K3S question In-Reply-To: References: Message-ID: It is easy to do and well worth the small amount of time and the cost.

A CME just missed the earth earlier this week. Plus the SFU is getting rather anaemic at 71. But the right time of day on the right band can work wonders. Late at night on the low bands has been fun; the higher bands not so much. Tomorrow we can test 20 & 40 meters again. Laziness is a virtue. If I can split wood with only one swing I can split more wood before I'm beat. If there is a knot I rotate the wood. If there is any crack I exploit it; natural cleavage lines are best. The optimal spot to set my wedge is about 1/3 of the way in on a radial line from the center (orthogonality is important). 1/2 way for smaller logs, as little as 1/8 of the way in for larger logs (4 footers). If I set the wedge too close to the center I work too hard; that triggers my inherent laziness.

Configure digital software to generate PTT, and use a foot switch on phone. Most digital programs support either software PTT (TX; and RX; commands sent before / after every message) or PTT via the RTS pin on a serial port. 73, Bob, N6TV On Sun, Mar 12, 2017 at 7:45 AM, K5MWR via Elecraft < elecraft at mailman.qth.net> wrote: > Bill > > Exactly the problem I have.

That's in addition to the superb lowering and narrowing of phase noise. I have this half notion to get a single rx K3 without tuner as "other RX" offband and rebuild platform in case other K3 has to go to Aptos, to keep me on the air. Move tuner from existing K3 to single rx one which becomes the field day rig. Never needed diversity at fd. Keeps me from having to undo all the home K3 wiring for fd. Point is that single rx K3 would have to have syn mod, or reduction in price. Moving forward for market value it has to have mods. Especially syns, D DSP and gold pins if early version. Since I have existing Microham stuff, serial cards in PC, etc, USB in K3S doesn't help me with anything. Still would like to have the K3S upgraded audio board for K3. When's that coming out? Been waiting. 73, Guy K2AV On Sun, Mar 12, 2017 at 1:56 PM James Walker wrote: > When faced with the upgrade question, my choice for spending the money was > to try out the IC-7300.

Since that computer (that successfully made the comm with my KX3) was the one I updated to Apple?s latest OS (10.12 - Sierra), today I updated the OS on one of the other Macs that had failed. Upon plugging in the KX3 and lighting up the KX3 Utility, it immediately connected to it. I don?t recall seeing anything in the Elecraft literature suggesting that 10.12 is required? but it definitely seems to help. I?ve now talked to the KX3 with two different computers. How reliable that connection might be, I suppose time will tell. FYI, Rich? Aye, my KX3 is new, fresh from the mothership. If I encounter this problem again I?ll try dropping the baud rate. And, yeah, guys? MacLoggerDX has most definitely not been up while I was trying to use KX3 Utility.

I bought a used station (KX3/PX3/KXPA100) and discovered that the communication baud rate with the amp in the station was 9600; and the baud rate standalone was 38400. It took a couple macro commands from the helpful folks here on the reflector to fix it but it sounds like your problem, transient though it is, lies elsewhere.

My RBNs typically indicate >50 dB SNRs at East Coast RXs and it's nice to be a good neighbor on a band that has very strong local signals. In the ARRL CW DX there was a multiop station in Mass that had bad clicks +/- 1 kHz, so I notified the owner afterwards. Turns out he was using an unmodified FT-1000MP which is notorious for clicks; he had the parts for the mod but had not yet done it. Shame on Yaesu for stonewalling this problem for years. Fortunately MPs are becoming scarcer by the day. Thank you Elecraft for producing one of the best quality CW signals and not allowing owners to shorten rise/fall times to intentionally create dirty signals. 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-upgrade-to-K3S-question-tp7627908p7627937.html Sent from the Elecraft mailing list archive at Nabble.com.

It added a Low Pass Filter to reduce the high audio filter response which eliminated some high frequency 'hiss' that some operators objected to. Secondly, it changed some capacitor and resistor values which enhanced the low frequency response. You can do the DSP board swap if you want both. But if you are only interested in the high frequency end, Elecraft provides an inexpensive kit to add the LPF to your existing DSP board. That was my choice because I was not interested in the extended low frequency response. 73, Don W3FPR On 3/12/2017 6:37 PM, gt-i at gmx.net wrote: > Bill, > > Good to know there is a DSP Update - didn't recognized it yet.

Its one which I've recently completed so its got all the latest updates etc. I searched the archives from this group and only found questions about QSK, which is different from what I'm hearing. On receive I've noticed that there's a bit of a popping sound which is in sympathy with the received signal level. So in other words if the bar graph S meter is sitting on 1 bar and the noise level is causing the second bar to briefly light the popping noise in the audio happens as the led bar lights on and off. I was wondering if it was caused by the bar LED its self, so i disabled it in the menu to eliminate it. I've monitored the purity of the audio signal on my oscilloscope with a signal from my XG3 and I get a really nice clean sine wave at the frequency received. Listening to this stable signal also sounds great. So my issue is only with amplitude changing signals. As you would expect I can see the very brief spike on the scope when it "pops". If I turn the KAF2 on the popping noise appears to go away. I've tested this on headphones and the internal speaker, I even tried my original K2 top with the speaker just to eliminate that too. Has anyone else noticed this? Do I have a problem with my K2/10? This doesn't happen on my K2/100, which is how it jumped out to me. I haven't as yet done any tracing back though the audio path. I wanted to check here if anyone else has noticed this or if I do in fact have a problem somewhere. Any info anyone has that might help would be much appreciated. thanks, Cameron, AF7DK/GM7LQR From pgladysz at aol.com Sun Mar 12 23:09:41 2017 From: pgladysz at aol.com (Pete Gladysz) Date: Sun, 12 Mar 2017 23:09:41 -0400 Subject: [Elecraft] Logging Software, P3 and the new KiOB3 Cables Message-ID: <005d01d29ba7$41f366c0$c5da3440$@aol.com> I upgraded the KIOB3 principally to eliminate the requirement for Multi Port software. I have a K3 , P3, SteppIr Interfaced with Logging Software and regularly use HRD and N1MM+ . I rebuilt the S13 cable that I had originally built into a S26 cable as suggested by Steppir. This was accomplished by eliminating the wire from PIN 7 to each connector. As I have 2 steppirs, I reprogrammed the DIN command to Baud 36400 and the Transceiver type to Kenwood. The computer is interfaced thru the USB to USB new cable. Using the new RG-45 to DE-9S connected to the K3, and my cable made like a S26 cable to the SteppIr controllers, I was able to gain control of the SteppIr Antennas with both N1MM+ and HRD Software. SUCCESS I then connected the DE-9S to my P3 and connected the S26 cable to the PC Out on the P3 and to the Steppir controller, and again I acquired control of the SteppIr's with either N1MM+ or HRD. But, the P3 is not receiving the correct data and is offset about 5 Khz. OK, so I had the suggested CBLP3Y cable so I tried it connecting to the K3 and connected to the back of the P3 Trans In connector. I had left the S26 cable in the PC out connector of the P3 to the SteppIr's. The P3 is now working correctly But... I tried to boot up both HRD and N1MM+ and neither would boot to support the radio. The Steppir's continued to track the frequency. I am looking for any suggestions. I am traveling with the K3 but not a P3 and will be connecting to a 4 Element SteppIr in Hawaii for the CQ WPX contest. That cable package works. 73, Pete K8PGJ From abullington at comcast.net Sun Mar 12 23:19:29 2017 From: abullington at comcast.net (abullington at comcast.net) Date: Sun, 12 Mar 2017 23:19:29 -0400 Subject: [Elecraft] K3 and PSK 31 Message-ID: I've really been enjoying my new used K3.

That's about the only time I venture into the RTTY segment, and I would generally rather just rag chew on CW, but snagging another DXpedition band slot this way is fun. It sure beats the heck out of the way I had to do it in the Army eons ago, with those model 21's, or whatever the nomenclature was--I've forgotten now. That was in an AN/GRC-26 van, with a BC-610, an R390, and a rack panel filled with other stuff. It sure got hot inside those vans!!!! With the K3, I can do it all on a TV tray!

This sounds more like the USB<>KX3 cable driver firing up as a Serial port that the updater was not defaulting to. That can happen if there is something else already connected to the computer that provides a "Serial" port for some other reason, before you plug in the KX3 cable. I've never seen the KX3 utility run on an Apple box, but on Windows and Linux, you get a chance to find and specify the serial port to use. 73 Dave G0WBX.

I have done the synth upgrades but none of the others, yet. I am considering doing the KXV3B and the KIO3B. At present I have a PR6-10 hanging off the back of the K3. I have found it very helpful on 10 meters and on 15 and maybe a bit on 20. I have not done any laboratory-grade measurements, but a simple on-off on 15 is convincing that the preamp is of use there, and 20 is maybe or maybe not. The KXV3B Manual is clear that band selection should be done on 12, 10, and 6. I would be disinclined to doing the upgrade if I lost the preamp advantage I now have on 15. Does anyone know if the preamp in the KXV3B is identical to the outboard PR6-10 and, if so, whether the K3 with an new KXV3B will accept the preamp ON designation for bands other than 12-10-6?

The new board preamp only works 12 through 6 M. More gain would be helpful on 17 and 15 M. I hope Elecraft can open up access to the new preamp on those bands-even if it is 6 dB. My experience (older K3) with an external preamp and decent antennas showed that some extra gain on 17 and 15 M helped. 15M is an especially quiet band and extra gain was welcome. Also it helped overcome the 3 dB loss in signal when the subrx was sharing the main ant. Now that I have relocated to another QTH and have much poorer antennas and lower sunspot numbers, the extra gain on 15 and 17 would be welcome. Most guys are hearing me better than I am hearing them. More gain on those bands might open up new layers of guys to work. Of course there is the question guys always ask : Why does it do anything placed at the RX front end. The fact of the matter seems to be that even if you just think it helps, it is a benefit. Measurements made with a signal generator show the new preamp does improve the MDS under the condx of no atmospheric noise present. Some of this might indeed show up for quiet bands. 73 de Brian .

Being also a proud owner of an old and fully upgraded K3 I found this little rig very familliar to operate and navigate. Very lovely package of all what you need on QRP, including the battery pack and the key paddle! I am especially amased by the built-in microfone - it works very nicely and I am re-descovering the SSB mode being mainly the CW op! The RX audio quality of SSB signals is outstandingly pleasant even with this small speaker! The general sensitivity of the receiver though seems a bit too low compare to the K3 thus the preamp is needed most of time even with good antennas. But that is no problem. A strange bug appears to live in the radio. It only related to 80m band LSB mode. It is not possible to get the signal transmitted if you are on 80m on power-up or if you come to 80m LSB from another band. Pushing Xmit or mics PTT puts the rig into transmit mode but RF meter shows no output. If you want to transmit, you have to change the mode into CW, transmit a dot or so ( it always works on CW ok ) then change back to the LSB mode and then only it starts transmitting your SSB signal out. The bug is NOT related with the " RF in the shack" case, it is there with different antennas and the dummy. The bug is permanently there and does not depend on battery supply, voltage, etc. I have also tried to reload the latest firmware , no change. So I think it could be the firmware problem. Would be interesting to know if anybody else experiencing the same strange effect? 72! de Linas LY2H KX2 #1488 K3 #1568 S-upgraded From shfoster at usa.net Mon Mar 13 10:34:38 2017 From: shfoster at usa.net (steve foster) Date: Mon, 13 Mar 2017 07:34:38 -0700 Subject: [Elecraft] For Sale KPA500 KAT500 combo Message-ID: <19c9d1d1-c498-010d-ca59-21f5e5cacb05@usa.net> KAT500/KPA500 both built from kits, non smoking home, excellent condition.

There is no reason to send CW and have the RTTY come out at a slow speed which is rude to the other operator.

But it?s been a while. The sub-receiver is actually pretty easy to pull and reinstall. Just follow the instructions that come with the mod kits. I?ve found the best way to ?sight? the sub receiver re-install is to first target the connector at the rear. It?s easier to see and line up. The front connector will fall into place. Biggest issue (exacerbated if you have the 2M xvrtr) is keeping the TMP cables out of the way while dropping it in. Be aware that the KBPF3 mod requires installing 3 0603-sized surface mount caps. These things are literally flea sized and NOT easy to deal with if you aren?t familiar with handling them. Elecraft supplies an extra in case you lose one. Best to use a hot air rework tool IMHO, but can be done with a fine tipped (ESD-safe) iron. Either way, I?d suggest liquid flux (if you don?t have any) to make it as clean and easy as possible. Can?t comment on the battery.

I did set the QSO selector to X, and it transmits now when I send. At first, if I double-clicked in the S pane to capture the callsign, it would clear the callsign when I then clicked in the X pane. I *THINK* setting QSO selector to X allowed me to capture the call in S and still transmit via X. However, after unkeying I observed the following: I could hear what sounded like band noise, and saw some background noise in WinWarbler, but looking at the P3 panadapter I could see the big signal I should have been hearing. Tapping XFIL brought the signal back into my headphones and onto WinWarblers display. Also, before doing this I had gone through the K3S config menu to confirm the right filters were set for DATA receive. I also made sure that in DATA the filters were centered at 2.21 kHz. My offsets are set to 2210 as well in WW. Also, tapping the XFIL button, while it should pick the other (of two) installed filters instead just brings back the audio... it doesn't swap to the other filter, just to the one I had already selected. I'm cross-posting to the Elecraft group to see if anyone can tell me what I might be doing wrong...

Also, lying flat the battery does not need a protective cover. Yes, the battery lasts a very long time, like the bios battery in your computer. All it does is keep the real-time clock running when power is off. The battery is unimportant if you don't use the clock. If you do use it or just want to have good battery in place, why not change it after 5 years if you are "under the hood" anyway? You need a CR2032 3-V battery. I would remove the left side panel (the side panel with the handle) along with the top cover, Then loosen the two long screws that hold the KRX3 enclosure in place and lift it enough to take the battery cover off and replace the battery. Having the side off makes it easier to ensure the interface boards between the KRX3 module and the RF board are seated when you replace the KRX3 module. With a little care you won't have to disconnect the TMP coaxial cables. Be sure to replace the battery cover. The positive (rim) of the battery can short against the bottom of the KRX3 enclosure if it is left off. When you replace the side cover, be sure to replace all SEVEN screws, including the one near the forward end of the handle. That screw is easily overlooked but is essential for proper shielding. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Dauer, Edward Sent: Monday, March 13, 2017 2:12 PM To: elecraft at mailman.qth.net Subject: [Elecraft] KBPF3 mod kit I just ordered the KIO3B and a KBPF3 mod kit for the K3.

If you do not use the internal clock, then do not bother. When you have the K3 open, it is an opportune time to replace it, but those batteries last a long time in an application when it is only keeping the clock chip active (as is the case in the K3). Compare it to the battery in a computer which does the same function. How many times have you had to change the battery in your computer? 73, Don W3FPR On 3/13/2017 5:11 PM, Dauer, Edward wrote: > I just ordered the KIO3B and a KBPF3 mod kit for the K3.

I also have a ARR 6m gasfet preamp mounted on the 6m tower for eme and use DIGIOUT-1 to select either preamp with the ARR on the bypass connector of the PR6-10. What I got from reading of the original problem was that there was insufficient gain in the K3 Rx chain at high-end frequencies to provide adequate sensitivity, so the preamp mainly adds gain to the chain. Fact that the NF is a little lower does not hurt if you are in a low noise environ. On 6m-eme local band noise floor is the prime limit on MDS, other than needing more antenna gain (single yagi 13-dBi). 15 dBi is considered the minimum for realistic eme reception. That seems to be my circumstance where other stations see my 1000w long before I see them (I have to use ground-gain enhancement to see eme). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From kg1gem at gmail.com Mon Mar 13 17:52:11 2017 From: kg1gem at gmail.com (Tim Elwell) Date: Mon, 13 Mar 2017 16:52:11 -0500 Subject: [Elecraft] Traveling Power Supply for KX2?

First of all, you need a soundcard. If you have installed the KIO3B in that K3, there is an internal soundcard in the K3 that can e used. If the KIO3 has not been upgraded, you will need a soundcard external to the K3. Either an internal computer soundcard or an external one. The computer must send audio to the K3 Line input and receive audio from the Line Out of the K3. HRD (or Win4K3 or other applications) will provide rig control functions without the audio paths. For instance, PSK31 (and other data modes) sends audio tones to the K3 via the computer soundcard, and receives audio tones from the K3 for decoding. Set the K3 to DATA A submode (AFSK A for RTTY), and during receive, adjust the computer Line In (or Mic) level to give you a good waterfall display. You can also adjust the LINE OUT level in the K3 menu. For transmit, adjust the soundcard Line Out (or Speaker) slider to about 75% of full and then in the K3, set the MIC SEL menu to LINE and adjust the "MIC GAIN" (actually LINE IN gain) so you have 4 bars illuminated solid on the K3 ALC display with the 5th bar flashing. Adjust the desired power level with the K3 power knob. Ignore the internet advice (and some software applications) to set the power to max and adjust the power output with the audio level - that does not work well with Elecraft gear. That advice is for other transceivers which do not control the power output by actually measuring the power level and making adjustments to make the power equal to the requested power level. Use the instructions in the K3 manual - paraphrased above. 73, Don W3FPR On 3/12/2017 11:19 PM, abullington at comcast.net wrote: > I've really been enjoying my new used K3.

After some experimenting, I find that my K3S will shift the receive frequency after transmitting in RTTY (FSK D Data mode.) Finding a busy band, I can see that if I tune in 5U5R exactly on 14.080.000, then send a RTTY transmission that after the RTTY transmission ends my rig is now still showing 14.080.000 on the screen but I am receiving a signal from somewhere around 14.078.78, near as I can make out from the P3. There's another data mode being used down there and the fellow has a nice, strong signal that comes and goes so I can tell when the signal starts and stops. This happens when I send from the keyboard as well as from a macro. I first noticed this in live transmissions but have spent the last half hour in TX Test mode, and the same thing happens even with no output. As soon as I tap XFIL the filter setting doesn't change but there the 5U5R is again. Alternatively, if I rotate the Shift knob either direction, the 5U5R is back. The FC is set to 2.21 kHz. Alternatively, if I rotate the width control in either direction, it goes back to receiving the 5U5R. This only happens when I am using the 400 Hz 8-pole filter or the APF (which also uses the 400.) When I use the 2.7 5-pole this doesn't happen. This feels like something is applying an offset of 1220 Hz while I transmit and not letting it go. But I'm at a loss to figure it out. My digi app is WinWarbler, and I have AFC unchecked. It shows a steady freq for xmit and rcv at 14.080.000 during all this. 1220 is just about half of 2210, so there's that. Also, the K3S TX Test mode doesn't key the finals, so there's no RF getting into it. This feels like something is set wrong, but blimey if I can figure it out. 73 de Chuck, WS1L -- =================== Chuck Chandler chandlerusm at gmail.com =================== From jcox123 at bellsouth.net Mon Mar 13 20:43:38 2017 From: jcox123 at bellsouth.net (Jim Cox) Date: Mon, 13 Mar 2017 19:43:38 -0500 Subject: [Elecraft] Elecraft P3 + extras for sale In-Reply-To: <20306D3A7E6F4EF1BC9D283A0C397A2A@JimPC> References: <20306D3A7E6F4EF1BC9D283A0C397A2A@JimPC> Message-ID: <7F1A049416BE4353A615C13B409C8775@JimPC> Unit has been sold..

I had either seven bars (Mic setting 3 or above) or none! The bars were solid...no flicker anywhere. On-the-air checks detected nothing wrong with my audio or signal...but I had 7 solid ALC bars! I was using a CM-500, plugged into the rear panel (rP.H bIAS selected). Elecraft support suggested that to set Mic gain properly that I first set CMP to zero, reset TX Eq settings, then set the Mic gain. I tried that and still had the failure. I tried several other things: latest firmware upgrade, re-installing a known "good" configuration file, trying another mike (older lightweight Heil with DX element), reseated the KIO3 boards several times to assure a good contact, and even a borrowed mike that I plugged into the front panel (FP.H bIAS selected) -- all produced the same results, seven solid ALC bars or none! Support re-iterated that I try re-loading a known good configuration file. I did that again and it still failed. Then I thought back to his suggestion about setting the Mic gain properly; this time, instead of resetting the settings manually as I'd done before, I hit the CLR button instead, and the settings were reset. THAT WORKED! I was now able to adjust the setting so I would get the last bar to flicker. I could also see, if I was careful enough, the ALC reading increase from zero to seven bars, something it wouldn't do before. I've increased CMP back to the way I liked it but haven't played with the TX Eq yet...gun shy! I thought I'd pass this along, right or wrong, just in case it helps somebody in the future. 73, Bert N4CW From jim at audiosystemsgroup.com Mon Mar 13 23:53:23 2017 From: jim at audiosystemsgroup.com (Jim Brown) Date: Mon, 13 Mar 2017 20:53:23 -0700 Subject: [Elecraft] P3 Phase noise/HighSignal Response? In-Reply-To: References: <20306D3A7E6F4EF1BC9D283A0C397A2A@JimPC> Message-ID: <76e11a84-9600-4936-7ab5-2f84cef69d77@audiosystemsgroup.com> Hi Dave, The P3 is quite good for measurements, and the SVGA card is even better. Here's a collection of work I've done with whatever rigs and amps I could get my hands on to measure. http://k9yc.com/P3_Spectrum_Measurements.pdf In my experience, if you keep the K3 within its linear region, you'll get good data from the P3 if you understand the measurements you're making. Limitations -- the dynamic range is 100 dB, but you can only display 80 dB on screen. For all of the operation I do, I use the P3 with a lot of averaging and a slow waterfall, fairly large waterfall. For measurements, I use the P3 in Peak reading mode and let it accumulate peaks for a while. I make the amplitude display pretty large, set it for 80 dB, and adjust levels to fill the amplitude screen. When I'm checking CW bandwidth, I send a series of dits in the range of 35 WPM for at least 20 seconds I reset the peak a second or so after I've started sending dits so I don't see any initial transient that might be present. Notice that I set the span for a fairly narrow bandwidth. The annotations you see for bandwidth are obtained by moving the cursor to each data point and writing down the readings, and they are the DIFFERENCE between the high and low points. If you want to show data more than 80 dB below the peak of the signal, you can repeat the measurement with the reference level reduced by 20 dB. More than that and the P3 will overload. 73, Jim K9YC On Mon,3/13/2017 6:03 PM, K5MWR via Elecraft wrote: > I am trying to use my P3 to evaluate signals from other hams here in > my community.

I too was dissatisfied with the K3's sensitivity on 10 and 12 meters so I experimented with some CATV preamps I bought at flea markets for $1. These provided good gain all the way down to 10 Mhz! When the PR6-10 came out I bought one. I felt that the PR6 -10 is/was a great preamp and better than the preamp in the original K3. When combined with the internal preamp, the results are outstanding down through 14 Mhz. There is an internal high pass filter the PR6-10 which cuts off gain below 14 Mhz. The PR6-10 has a major weakness. The RF transistor is very sensitive to static and RF voltage. I have destroyed two of the microchips, one I believe due to static buildup and one due to a spike from my 6 meter amp, a converted SB-200. I still have my PR6-10 but most of the time, I am using my cheap $1 preamp on 20 through 6M. The current one is a Gemini DA1100 cable VCR VHF/FM 10 db amp covering 50-450 Mhz. Again, they work all the way down past 10 Mhz. This little units have a built in power supply and are usually a little chrome box. They might also carry the name RCA or Radio Shack but are essentially the same. I use short patch cables to switch them in and out. Even though they are 75 ohm in/out, it doesn't seem to affect operation. For the above reasons, I won't do the preamp upgrade board for my K3. 73 Dennis W0JX From nineback at gmail.com Tue Mar 14 10:33:39 2017 From: nineback at gmail.com (Tom) Date: Tue, 14 Mar 2017 09:33:39 -0500 Subject: [Elecraft] Roofing Filters Message-ID: Is there an easy way to tell what roofing filters are installed short of opening up the radio.

You can view photos and place an online order here: http://bit.ly/Y-BOX Highlights: - Splits one ACC port into four DE-15 female connectors - all 15 pins plus the shield are wired in parallel to every connector - Replaces "VGA splitters" that easily pull apart with reliable thumb-screw connections - Provides four RCA connectors that may be connected to any of the 15 ACC port pins (or to each other) with standard wire jumpers, e.g.: FSK IN, PTT IN, KEYOUT-LP. Ideal for experimentation and measurements as well as connections to legacy devices - Includes six internal jumper wires, pre-installed in one of two configurations - the function of each K3 ACC header pin is clearly labeled on the PC board for reference - Includes one 10K ohm and one 470 ohm resistor to create a Simple SO2R Lockout Circuit (see http://bit.ly/K3lockout and the "Y-BOX Features and Uses" page on the Y-BOX web site). - Includes one (optional) Amphenol 2.5' (0.76m) Male-to-Male DE-15 cable to connect the Y-BOX to the K3 ACC port. Reviews from early adopters (local club members and K3 Field Testers) have been very positive. eHam reviews will appear here: http://www.eham.net/reviews/detail/13296 Note: the Y-BOX is not an Elecraft product. It was offered to Eric, but he doesn't want to take on another project at this time. The Y-BOX is currently available for immediate shipment, but in limited quantities. When the initial inventory sells out, you may add yourself to the Y-BOX Waiting List at no cost (via the PayPal "Continue Shopping" button). Once enough orders are on the waiting list, I'll attempt to acquire enough parts to meet the demand. In sum, you can get one right away if you order right away, then it may be another month or two before I can get all the parts required and build another batch. "The Y-BOX, Why Not?"

If I select the rear panel microphone, it works as expected and the front panel mic is muted. If I select the front panel microphone it works OK, but the rear panel microphone is also unmuted and transmission sounds like two voices at the same time, probably due to the two mics being out of phase. Is there any way of selecting the front panel microphone only, with rear panel mic plugged in? As both microphones are electrets, the only way I can think of getting round it temporarily is to turn the bias off on the rear panel mic, when using the front panel mic, which is inconvenient and not a ?clean? solution. 73, Alan.

Just try to "enhance international goodwill" with a human to human conversation in a DX pileup. The only difference between having the K3 to send the RTTY and your computer/soundcard/software doing it is that the human on the K3 using the keyer is slower and makes mistakes (unless he/she can do 60wpm mistake free, not likely). Same thing applies using the K3 memories. No difference between that and punching a function key on a computer keyboard. Should we outlaw computer sent RTTY and how can you tell the difference other than the computer makes no mistakes? I would advise whoever sent the email to walk the talk, get off the internet and take up pen and paper again. You know, for that human to human personalization thing. On 3/13/2017 2:40 PM, Lynn W.

Here is the appropriate section: I was told that basically there was no place for ragchewing in Amateur Radio -- no place at all. 97.1(e) says there is a place for a good ragchew. Not sure where contesting comes in, but I'll stipulate that it can be fit into 97.1 somewhere. It does not say that every place is a good place for a ragchew, at any time. It seems intuitively obvious that a DX pileup is neither the time nor the place. You then compare typing on a keyboard to using paddles, and going back to the post just before mine, it was about using pre-programmed macros for a contest exchange. The operators aren't really talking. They're pressing two macro keys and making an entry in the log. NO MATTER WHAT IT IS, WHAT YOU LIKE TO DO, SOMEONE WILL SAY "THIS ISN'T AMATEUR RADIO." I do respectfully disagree. It may not be what I want to do, but I've seen the Full-Scan TV ops get very excited about their favored mode. Moonbounce doesn't excite me, but it excites moonbounce enthusiasts. Satellites? Did it once, happy to know about it, not enough to really gear-up for it. There is room for all of this in Amateur Radio. ... and I'm more than happy to do something else on big Contest weekends, and to steer clear of the pileups. I won't name the person I quoted, but his technical contributions are significant. He'd still rather carry on a conversation than just send macros. In my opinion, it is a little bit sad that we have reduced communication to a couple of macros. I don't require you to share that opinion, Kevin, nor will I deny you the pleasure of operating that way if it's what you love. I won't ridicule it either. 73 -- Lynn On 3/15/2017 3:45 PM, Kevin wrote: > Ridiculous! > > Just try to "enhance international goodwill" with a human to human > conversation in a DX pileup. > > The only difference between having the K3 to send the RTTY and your > computer/soundcard/software doing it is that the human on the K3 using > the keyer is slower and makes mistakes (unless he/she can do 60wpm > mistake free, not likely).

There is a season for every purpose under Heaven" Those words of Pete Seeger ring in my head. It is the same on the hambands. There is a time for ragchews and there is a time for contests, and there is a time for DX contacts which are looking for the maximum number of QSOs. On contest weekends, do not expect ragchew QSOs with those who are contesting. For DX contacts who are trying to maximize their contacts, the will not be willing to ragchew. If you want to ragchew, then do it with stations that are also willing. Send them a bit of personal information and see if they respond. If not, they are not willing to ragchew. Bottom line - it all depends. It takes two to make a conversation. 73, Don W3FPR On 3/15/2017 8:44 PM, Lynn W.

Contests simulate emergency communications, where getting a message (the contest exchange) through accurately and quickly is very important. I enter several contests a year, and retreat to the WARC bands when I don't want to play in a contest. DXing builds operator skill in pulling information out of very weak signals. It also supports an amazing number of international trips to put rare entities on the air. I chase DX and dream of getting to be a good enough operator to join a DXpedition. I think Nigel Jolly would agree that amateur radio has helped build international understanding. Rag chewing builds operator skills, as well as ensuring that people's equipment is still working. I like a good rag chew and I have been known to chat back and forth for 15 minutes to 1/2 an hour on PSK-31. (Note that as a retired software guy, I can type reasonably well.) I could go on and on, but you get the picture. 73 Bill AE6JV On 3/15/17 at 5:44 PM, KX3 at ColdRocksHotBrooms.com (Lynn W.

So exchanges were short even without a contest. And visiting friends in Cuba was off-limits for us Americans. Still, I believe those contacts had a positive effect. Just participating in the contest enhances international goodwill in a small way. Yes, the internet and softening of relationships has changed the role Ham contacts have, but they are still part of the international goodwill equation. I submit that is true in its small way even of automated context exchanges. And Ham contacts have changed too. Time was, a few weekends a year one might find a contest in progress. Now it's hard to find a contest-free weekend on the CW bands where I hang out. But that is what a great many Hams enjoy. Personally, as a rag-chewer, I have over the past 60+ years of pounding brass made several life-long friends by Ham radio. Only a few I have managed to visit personally since they are scattered world-wide. Most of the memories are fixed by QSL cards - real paper cards sent via the "burro". Others by a memento of a personal visit, such as the nice carved AC7AC call sign I have on my desk from a great fellow in The Netherlands when I visited him. And it is true that instead of many on-air QSOs over a few years as in decades long past, we often resort to e-mail. Indeed, some started via e-mail right here on the Elecraft reflector. Maybe "enhance international goodwill" as a justification for Ham radio will come to an end along with rag-chewing, but somehow I doubt that will happen. People everywhere are more comfortable with others who they know and with whom they share some common interests. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Lynn W.

Here is the appropriate section: I was told that basically there was no place for ragchewing in Amateur Radio -- no place at all. 97.1(e) says there is a place for a good ragchew. Not sure where contesting comes in, but I'll stipulate that it can be fit into 97.1 somewhere. It does not say that every place is a good place for a ragchew, at any time. It seems intuitively obvious that a DX pileup is neither the time nor the place. You then compare typing on a keyboard to using paddles, and going back to the post just before mine, it was about using pre-programmed macros for a contest exchange. The operators aren't really talking. They're pressing two macro keys and making an entry in the log. NO MATTER WHAT IT IS, WHAT YOU LIKE TO DO, SOMEONE WILL SAY "THIS ISN'T AMATEUR RADIO." I do respectfully disagree. It may not be what I want to do, but I've seen the Full-Scan TV ops get very excited about their favored mode. Moonbounce doesn't excite me, but it excites moonbounce enthusiasts. Satellites? Did it once, happy to know about it, not enough to really gear-up for it. There is room for all of this in Amateur Radio. ... and I'm more than happy to do something else on big Contest weekends, and to steer clear of the pileups. I won't name the person I quoted, but his technical contributions are significant. He'd still rather carry on a conversation than just send macros. In my opinion, it is a little bit sad that we have reduced communication to a couple of macros. I don't require you to share that opinion, Kevin, nor will I deny you the pleasure of operating that way if it's what you love. I won't ridicule it either. 73 -- Lynn On 3/15/2017 3:45 PM, Kevin wrote: > Ridiculous! > > Just try to "enhance international goodwill" with a human to human > conversation in a DX pileup. > > The only difference between having the K3 to send the RTTY and your > computer/soundcard/software doing it is that the human on the K3 using > the keyer is slower and makes mistakes (unless he/she can do 60wpm > mistake free, not likely).

It's a tiny crescent-shaped knife with a handle that you put into a hole and rotate. You can hold it at an angle to remove burrs from drilling, or straight to enlarge a hole slightly. It can be used on straight edges after sawing, too. It takes a very small bite and does a neat job.

To send reduced power to the KAT500 for its tuning, press the TUNE button on the K3. If you take the time to 'train' your KAT500 by allowing it to store tuning settings up and down each band, you never have to worry about it again. Ideally, you program the KAT500 to switch antennas automatically and not have to worry about manually switching. Not so of course if you use multiple antennas for the same band. Since you only connect from one antenna port on the K3 to the KAT500, I'm not sure how the K3 ANT button would switch to different antennas on the KAT500. To me it's actually easier to change antennas using the KAT500 ANT button. These are all just my experiences. 73, Mitch NW?M -- View this message in context: http://elecraft.365791.n2.nabble.com/ATU-Tune-with-the-KAT500-tp7628038p7628040.html Sent from the Elecraft mailing list archive at Nabble.com.

In-Reply-To: References: Message-ID: Chuck, Removing the front panel is easy. It is separating the front panel and DSP board which is more involved. All you have to do is remove the screws and pull the front panel board off. There are rectangular cutouts on the bottom which can be used to pry the front panel off with a screwdriver. The many pins provide a good grip, so you have to pry it off a bit. With the K3 (not K3S) you had to remove the left side panel to allow you to remove one screw from the RF Board to 2-D connector which interfered with the removal of the Front Panel assembly, but the K3S has a notch in the board and that step is not necessary. 73, Don W3FPR On 3/16/2017 10:01 AM, Chuck Chandler wrote: > I will be putting my K3S on the bench this weekend to try to trace an > intermittent bug.

However, going to 1,500 watts from 500 watts is a bit less than 5 dB -- a little less than one International Standard S-unit. 5 dB might come a lot cheaper from an antenna change. Before purchasing the KPA500, I ran my "1,500 watt Behemoth" at 500 W for close to a year to see if I could tell the difference. Admittedly, I'm a casual contester and DX'er, and I operate my ham radio for other reasons too, but I really couldn't see much if any difference in terms of who I could work or how long it took to snag the latest expedition. Operating skill [or lack thereof in my case] was a much bigger factor. The KPA500 was full QSK which its predecessor was not, which became a big advantage. I have since sold the KPA500 [and KAT500] and run 100W from home. My HOA-Stealth "wire on the fence" is close enough to the house that I occasionally make something happen [like flash touch-lamps or reset the u-wave clock], and I figured 500 W might nuke the neighbor's dog who patrols the other side of the fence. I'm very surprised that the wire, 6 feet high, works as well as it does. If I quest for QRO and "real antennae," I can always run W7RN remotely. 73, Fred ("Skip") K6DGW Sparks NV USA Washoe County DM09dn On 3/16/2017 12:26 PM, Erik Basilier wrote: > I recently sold my legal limit tube amp after a bit of a mental struggle. > The seller in me finally won after I realized that "if I can't lift it, I > shouldn't own it".

AFAIK there are no other gold pin mods for the K3. I suggest removing the front panel and connectors and carefully re-seating them. You might also want to consider the use of De-Oxit, but do ask Elecraft first, as they may advise against it. Bear in mind that this is a computer issue where signals from switches are multiplexed. If one connection gets disturbed, it will affect the action of several switches and give weird intermittent results, with some being seemingly unrelated. 73, Alan.

If they are tin, then they should be replaced (only the male pins, the mating female is already gold). Elecraft will supply a "kit", I believe at no cost. Often just removing and replacing the connectors will solve 'strange happenings' because the process wipes away oxidation. If the pins are gold and the behavior continues, contact Elecraft support for further action. 73, Don W3FPR On 3/16/2017 3:58 PM, Fred Jensen wrote: > Related question: My K3 [S/N 642] which I built from the kit has > developed an "intermittent front panel problem," where tapping a switch > doesn't always yield the action it should.

It is an introductory preamble included there originally for political purposes, and after enactment for purposes of interpreting the regulations that are substantive, when questions about interpretation arise. The substantive regulations go from 97.2 ro 97.527, though there aren?t nearly 526 of them. Those are the sections that tell us what we can and, about as frequently, what we cannot do. The statement of purpose is legally speaking neither a grant of specific operational authority nor itself a limitation. As for international communications, the proscription of some forms of political discourse was not uniquely a product of the Soviet Union. The U.S. law is in 47 C.F.R. ?97.117 ?International communications: Transmissions to a different country, where permitted, shall be limited to communications incidental to the purposes of the amateur service [namely, the list in 97.1] and to remarks of a personal character.? I have not researched whether there are any judicial opinions or FCC policy statements that further explain that substantive rule. All of that said, nothing that anyone has written in this thread which they enjoy or dislike seems to me to be outside the scope of our legal authority. **HOW** we do it technically and in some respects operationally (e.g. deliberate interference) is of course subject to lots of rules. But the rest is a matter of culture, tradition, preference, and simple operating courtesy. On those things I do not opine. I do what I enjoy. Within the scope of the substantive law, of course.

Here is the appropriate section: I was told that basically there was no place for ragchewing in Amateur Radio -- no place at all. 97.1(e) says there is a place for a good ragchew. Not sure where contesting comes in, but I'll stipulate that it can be fit into 97.1 somewhere. It does not say that every place is a good place for a ragchew, at any time. It seems intuitively obvious that a DX pileup is neither the time nor the place. You then compare typing on a keyboard to using paddles, and going back to the post just before mine, it was about using pre-programmed macros for a contest exchange. The operators aren't really talking. They're pressing two macro keys and making an entry in the log. NO MATTER WHAT IT IS, WHAT YOU LIKE TO DO, SOMEONE WILL SAY "THIS ISN'T AMATEUR RADIO." I do respectfully disagree. It may not be what I want to do, but I've seen the Full-Scan TV ops get very excited about their favored mode. Moonbounce doesn't excite me, but it excites moonbounce enthusiasts. Satellites? Did it once, happy to know about it, not enough to really gear-up for it. There is room for all of this in Amateur Radio. ... and I'm more than happy to do something else on big Contest weekends, and to steer clear of the pileups.

Chuck, Removing the front panel is easy. It is separating the front panel and DSP board which is more involved. All you have to do is remove the screws and pull the front panel board off. There are rectangular cutouts on the bottom which can be used to pry the front panel off with a screwdriver. The many pins provide a good grip, so you have to pry it off a bit. With the K3 (not K3S) you had to remove the left side panel to allow you to remove one screw from the RF Board to 2-D connector which interfered with the removal of the Front Panel assembly, but the K3S has a notch in the board and that step is not necessary. 73, Don W3FPR On 3/16/2017 10:01 AM, Chuck Chandler wrote: > I will be putting my K3S on the bench this weekend to try to trace an > intermittent bug.

There are a growing number of lightweight legal limit amps already on the market. The FlexRadio Power Genius looks especially promising: http://www.flexradio.com/amateur-products/powergenius-xl/ It only weighs 33 pounds. I saw it in operation at the Orlando HamCation and it looked very impressive operating all weekend into a dummy load at a conservative 1.5 kw output. SPE also just announced a 1.5 kw amp..something I'm surprised they did given that they already have a 1 kw, 1.3 kw, and a 2kw amp on the market. I know of several people that have the 1 kw amp and use it with their K3 radios and they love them. I've used the big SPE amp in CQWW CW and it worked flawlessly all weekend without a hiccup.

The KPA500 runs very well off of a decent 120VAC mains source, as I can attest from experience. But that is about the limit for a normally (for the USA) wired home circuit when a power supply for a K3, lights, etc., are included. Larger amps will *REQUIRE* a 240VAC circuit which, unlike Europe, we in the USA seldom have unless special wiring is installed. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Bill Johnson Sent: Thursday, March 16, 2017 3:38 PM To: Charlie T, K3ICH; elecraft at mailman.qth.net Subject: Re: [Elecraft] Linear thoughts Charlie, I think one of the main reasons for switching to a smaller amp was the weight involved in the 1.5Kw rigs. Just thought I would add back in. The MJF AB1000 combiner looks interesting, but I would not touch one unless I knew of many who used one successfully. That way I could get a second KPA500, and run 1KW which adds the 3db and I could move the separate parts with ease. :-) 73, Bill K9YEQ -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Charlie T, K3ICH Sent: Thursday, March 16, 2017 5:20 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Linear thoughts Well, if you've never tried to work truly "weak" signals, I can assure you that +5 dB WILL make a world of difference. Otherwise, why would you go to the trouble of installing a ?dB noise figure pre-amp at the antenna, just to eliminate 2dB of feed-line loss on receive? Or, stacking a second Yagi to gain at most, +3dB? Yes, +5dB can be very hard to come by when you're operating at the fringes of performance. My thoughts are, if you're gonna run an amp at all, go for legal limit. Not knocking anyone running 200 or 500 or 700 watts, just my own opinion. 73, Charlie k3ICH -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Fred Jensen Sent: Thursday, March 16, 2017 4:35 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Linear thoughts Advising Elecraft about producing a larger amplifier is quite a bit above my pay grade so I won't go there. However, going to 1,500 watts from 500 watts is a bit less than 5 dB -- a little less than one International Standard S-unit. 5 dB might come a lot cheaper from an antenna change. Before purchasing the KPA500, I ran my "1,500 watt Behemoth" at 500 W for close to a year to see if I could tell the difference. Admittedly, I'm a casual contester and DX'er, and I operate my ham radio for other reasons too, but I really couldn't see much if any difference in terms of who I could work or how long it took to snag the latest expedition. Operating skill [or lack thereof in my case] was a much bigger factor. The KPA500 was full QSK which its predecessor was not, which became a big advantage. I have since sold the KPA500 [and KAT500] and run 100W from home. My HOA-Stealth "wire on the fence" is close enough to the house that I occasionally make something happen [like flash touch-lamps or reset the u-wave clock], and I figured 500 W might nuke the neighbor's dog who patrols the other side of the fence. I'm very surprised that the wire, 6 feet high, works as well as it does. If I quest for QRO and "real antennae," I can always run W7RN remotely. 73, Fred ("Skip") K6DGW Sparks NV USA Washoe County DM09dn On 3/16/2017 12:26 PM, Erik Basilier wrote: > I recently sold my legal limit tube amp after a bit of a mental struggle. > The seller in me finally won after I realized that "if I can't lift > it, I shouldn't own it".

The CAT control input on all the SPE amps have the same pinout and the amplifiers ship with the DB15 connectors and hoods. It's not rocket science to make a cable which is custom to your needs. Plus, you can take advantage of the key out on the K3 acc port and have the SPE amp control TX-INH if you want etc... making a cable up is probably easy enough that a typical cave man could do it, if he/she has bare bones soldering station etc... Download the manuals and spend some time studying up on what you can do and how to interface it with your K3... the last time I checked it's still legal to use a soldering iron and some wire strippers. If you order up cables, you will get what you get and there are several different things to consider when interfacing your rig with an SPE amp. Why not get what you want for cheap and learn something long the way rather than paying for some pre made cables in this case. ;) And yes, there are cases where we get older and have a hard time with tiny connectors etc... and our eyes get bad, so I get that. Get a ham buddy to help you out. Anyway... another thread lives on about Elecraft building a KW amp etc... the Ever-Ready bunny keeps going and going and returning. :) Max NG7M Max NG7M On Thu, Mar 16, 2017 at 10:54 PM, Jim Brown wrote: > On Thu,3/16/2017 8:36 PM, James F.

In-Reply-To: References: Message-ID: <003c01d29ef5$873acec0$95b06c40$@co.uk> When separating the front panel assembly, place the K3(S) upside-down on a smooth anti-static mat [1]. This ensures that the front panel cannot drop away when the two units come apart, and avoids bending any connector pins. Likewise when reassembling: place the two units upside-down on the mat, accurately line up the panel assembly with the main body of the K3(S) and then simply *slide* the two parts together on the mat. The more you remove and replace the front panel assembly, the easier the whole operation becomes because you are 'training' all the connector pins to line up more accurately with their matching sockets. [1] Please say that you always use an anti-static mat for these operations? 73 from Ian GM3SEK >-----Original Message----- >From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of >Chuck Chandler >Sent: 16 March 2017 14:01 >To: elecraft at mailman.qth.net >Subject: [Elecraft] K3S front panel remove/replace tips? > >I will be putting my K3S on the bench this weekend to try to trace an >intermittent bug.

Many US vendors get it right, but just as many don't seem to care, or even know that things are different outside of CONUS. Adapters supplied with "new" products are AFIK not permitted, though it often happens. The problem there, is the quality and safety of such adapters is often poor. (Often low cost brittle plastic things from the Far East.) In this case, as the PSU is intended to be used with a device that has exposed metallic parts connected to one side of the DC lead, I suspect (I admit that I do not know for sure) that the AC input to that PSU should include a safety ground, connected to (among other things) the transformer inter-winding shield. It's been a very long time since we've seen any similar PSU's for laptops and similar devices, that do not have a three pole power inlet, that includes a safety ground. Even, if the DC output is fully isolated from anything on the AC input side. Take care.

It is a great amp, although, I don't like the clunky relays and the fan noise to cool the tubes. Once in a while I like to not have to use cans to operate, but for the most part I do use the headphones. After having the Alpha and SB 220, and TenTec Titan amps the Alpha was the loudest. It is kind of an antique and it is my only piece of boat anchor equipment that I own. I bought a THP 1.5kfx amp and I have been running it at 500 watts when ever I turn it on. I can run it at 1k or 3db increase in power and from the other end there is no change in the rx station report. I run CW 98% of the time. But the amp is used on SSB for the rag chew on a local level and yes I use an amp to talk across town on 40 meters just to keep the cursing hog farmers and drunks from messing with us. It works well for that. People just stay away. But it also attracts the casual drop by who joins the QSO and is welcome to stay awhile. 500 watts for the last 3 years has been more than enough. It is easy to hold a frequency in a contest with that power and it causes no problems with neighbors. Since I only use balanced antennas, my RFI problems have disappeared. I can run 1500watts with no problems or lights going on and off and garage doors opening. It is nice to have some headroom in an amp and that is what the THP gives me. It just loafs at 500 watts. I run it on 220v and the panel lights don't even change intensity. I would vote for a 1k amp by Elecraft but probably would only run it at 750 tops. And No I don't need 6 meters so a 160-10 would be great. After all, Elecraft came out with the KX2 vs KX3 and did just that, 80-10 no 160 or 6, and I am just fine with that. So if they made an amp with 160 - 10 then that would be fine by me. It may be even as simple as saying with the software that the KPA 500 if the software were to change and state 750 watts 160-10 and 500 on 6, heck I would be even happy with that. Elecraft stuff just works and I am happy with that. I so want to pull the trigger on the KX 2 or 3 and it temps me every time I visit the page to see what new stuff has come out. In the near future, like right now, SDR radios are going to dominate the field and I really want to see what Wayne, has cooked up for dealing with that issue. SO2R is the wave of the future in contesting and K9CT is the poster boy for the Flex 6700 and Maestro interface when it comes to contesting. He sold all of his K3/P3 stations and has a full compliment of Flex. Maybe, if Elecraft made a great interface that would work with the K3S/N1MM then that is an area that should be explored for SO2R. Every thing is contingent on market share and perceived value. Face it K3 owners are rather an elite crowd. First we are buying radios, when fully equipped are nearing the $4k mark and from a cosmetic stand point of view, they are not pretty on the out side. Utility is everything for us, and simply the K3 works. In the end, if Elecraft made a better amp than the KPA 500, I would probably buy it. Maybe even 2 of them for my station conversion to SO2R. I know guys that buy 2 KPA500.KTA500 for running SO2R with the Flex 6700/maestro set up. It works well for them. Once I retire, I will probably do the same and run 2 k3s with them. It is the logical solution for me, especially since I love the quiet relays/pin diode switching and the almost silent fans when running hard with the KPA500.

SPE also just announced a 1.5 kw amp..something I'm surprised they did given that they already have a 1 kw, 1.3 kw, and a 2kw amp on the market. I know of several people that have the 1 kw amp and use it with their K3 radios and they love them. I've used the big SPE amp in CQWW CW and it worked flawlessly all weekend without a hiccup. ______________________________________________________________ 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 ctate at ewnetinc.com From monzi at netscape.net Fri Mar 17 11:26:42 2017 From: monzi at netscape.net (Monzi) Date: Fri, 17 Mar 2017 08:26:42 -0700 Subject: [Elecraft] Elecraft Digest, Vol 155, Issue 23 In-Reply-To: References: Message-ID: <378C8AF4-6D74-4A46-A493-DB9FCCAB3F43@netscape.net> WTB KPA500 and KAT500.

If you use these along with the RemoteRig boxes, then you will no longer need to have a PC running on the radio side. The RemoteRig boxes have two serial port servers built-in, but are both used for CAT if you use CAT with your Elecraft "Twin" system. If you don't want to use CAT, then COM1 on the RRC's is available to control another device. I use Lantronix serial port servers such as the UDS2100 https://www.lantronix.com/products/uds2100/, but there are a lot on the market. There are also dedicated boxes from RemoteRig called RC-1216H http://www.remoterig.com/wp/?page_id=1010 that provides a web interface for these devices. They are much more expensive that a simple serial port server and don't provide a redirector to use client software remotely, but are an "idiot proof" method for people that prefer that method of control. Using serial port servers allows you to use any client software for that device on the control side, including the SPE client. For any further questions or details, please contact me off list. 73, Mitch DJ0QN / K7DX Mitch Wolfson DJ?QN / K7DX 10285 Boca Cir, Naples, FL 34109 Skype: mitchwo USA: Home:+1-239-221-9600 - Mobile:+1-424-288-9171 Germany: Home:+49 89 32152700 - Mobile:+49 172 8374436 On 17.03.2017 12:30, 'DGB' wrote: > I am getting my remote setup. > > For hardware at the remote site (home) I am using a K3, Palstar > HF-Auto, SPE Expert 1.3k - FA Amp., Green Heron Products for Rotor > control and their wireless remote boxes for switching antennas, and > one Remoterig 1238.

Folks, if we did introduce a 1500 W solid state amp similar to our KPA500 in operation, what features etc would be important? 73, Eric /elecraft.com/ From w7aqk at cox.net Fri Mar 17 13:10:32 2017 From: w7aqk at cox.net (w7aqk) Date: Fri, 17 Mar 2017 10:10:32 -0700 Subject: [Elecraft] Linear thoughts Message-ID: This debate seems to get resurrected a lot. I think the reason for that is more philosophical than technical. Clearly 1 KW is better than 500 watts, at least in many cases. The question really is, do you actually need it, and can you make that leap practically. Answers to those questions will be all over the board. I run 500 watts because it is practical. I don't have a 1 ton brick to deal with, I didn't have to re-wire my shack, the lights don't dim when I go key down, and I don't apparently have RFI problems. I also only had to give up one arm and one leg (not both) to accomplish that financially--the cost/watt seems to go up significantly above that. If all those factors were neutralized, I might run 1 KW too! 500 watts is a lot of power! It gives me 60% of the maximum gain I can achieve legally (1 S unit down). 1 S unit is nothing to sneeze at, but I find that, usually, if I can hear them I can work them. More often than not, if I have a problem, It is hearing them. A bigger amp won't solve that. I could probably gain 2 S units or more, both on RX and TX, with somewhat better antennas. Well, that's a problem here too, but not for a lot of others. Invariably the "weak signal" argument is raised, and it's hard to refute. However, I really wonder how often that is really solved by a bigger amp. They may be weak on your RX, but the reverse might not be true. I'm just asking, not refuting. It does seem to me, though, that it is more a matter of out shouting other stations. On the other hand, it may be a matter of defeating the other person's noise level. Score 1 for more power. In fact, that may be one of the best arguments for more power. Anyway, I don't think there is an answer here--just options and consequences. A bigger amp is not a panacea--just an option. What I think I do know, however, is that we tend to run more power than we need, not less. Still, that depends on your philosophy. A lot of folks have V8's, when a V6 is plenty. Actually, I have a V8, but it just drinks more gas, and doesn't get me there any quicker.

This release offers a bug fix that showed up using DXLab Commander when you switched from a band that did not use the sub-receiver to one that does. There was an excessive delay. In the process, additional performance enhancements were made to the third party virtual radios in Win4K3Suite. One of the useful features of Win4K3Suite is that it interfaces to all 3rd party logging and digital mode programs such as HRDLogbook, DX Keeper, NAP3, N3FJP, N1MM+, FLDigi, MIXW as well as hardware devices such as the K3/0, the Pig Knob and various antenna tuners. In order to understand how to do this, there is now a video on youtube that gives clear instructions on using the virtual port management facilities of Win4K3Suite: You can access it at https://www.youtube.com/watch?v=1jh6IS0S1dE&t=4s There is no need for LPBridge, and you can wish you can even continue to use NAP3 if you prefer that interface. You can read a review about this here: http://www.eham.net/reviews/detail/11214 Please check out the 30 day trial at va2fsq.com and the videos on YouTube at https://www.youtube.com/results?search_query=win4k3suite 73 Tom --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From glcazzola at alice.it Fri Mar 17 15:00:06 2017 From: glcazzola at alice.it (glcazzola at alice.it) Date: Fri, 17 Mar 2017 20:00:06 +0100 (CET) Subject: [Elecraft] R: Re: Linear thoughts Message-ID: <15adda425be.glcazzola@alice.it> Great qsk with pin diodes, no noise, fast atu, no switching power supply.If possible not high price.

(flex amp). less devices, shack simplification and value... -ability to control device over Ethernet via remote without connecting via a serial interface, but keep the serial interface for legacy use (flex amp) the future is on ethernet. -some kind of ability to manage mismatches, probably a tuner either outboard like a kat500 or inboard would be better. one that is more resilient than the expert would be a market differentiator(expert amps but needs improvement) This would make it a killer device. Thats what comes to mind short term. ________________________________________ From: Elecraft [elecraft-bounces at mailman.qth.net] on behalf of Wayne Burdick [n6kr at elecraft.com] Sent: Friday, March 17, 2017 11:21 AM To: Wes Stewart Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] Linear thoughts On Mar 17, 2017, at 11:14 AM, Wes Stewart wrote: > Three times the power, one-third the cost? > > Somewhat more seriously: legal limit, internal tuner for up to at least 3:1 SWR (option?), optional separate power supply, quieter cooling.

This means the following: - Have API's that support complete remote control, also available to other software and hardware developers - If possible, allow remote power on via a remote command and not by providing a voltage to pins (like the old SPE 1K-FA did) - Do not use (only) USB control, since this is no good for remoting - Have a true serial port for serial port servers and other legacy devices - A bonus would be an embedded serial port server, such as the Lantronix XPort (OM Power offers this as an option) https://www.lantronix.com/products/xport/ - Another added bonus would be an embedded web server with a control interface, such as that offered on the RemoteRig RC-1216H http://www.remoterig.com/wp/?page_id=1010 Having helped to install dozens of amplifiers for remoting, I can say that this feature set would put a new 1500w amplifier on the top of the remote station heap if reasonably priced. 73, Mitch DJ0QN / K7DX Mitch Wolfson DJ?QN / K7DX 10285 Boca Cir, Naples, FL 34109 Skype: mitchwo USA: Home:+1-239-221-9600 - Mobile:+1-424-288-9171 Germany: Home:+49 89 32152700 - Mobile:+49 172 8374436 On 17.03.2017 13:06, Eric Swartz - WA6HHQ, Elecraft wrote: > Interesting discussion. > > Folks, if we did introduce a 1500 W solid state amp similar to our > KPA500 in operation, what features etc would be important? > > 73, > Eric > /elecraft.com/ > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to dj0qn at arrl.net > From johnbsaxon at yahoo.com Fri Mar 17 15:37:41 2017 From: johnbsaxon at yahoo.com (John Saxon) Date: Fri, 17 Mar 2017 19:37:41 +0000 (UTC) Subject: [Elecraft] OT: RFI problem on 80,40 with AT&T Uverse References: <243467085.2539458.1489779461352.ref@mail.yahoo.com> Message-ID: <243467085.2539458.1489779461352@mail.yahoo.com> Off topic, but perhaps others have had the same problem.

My input is as follows: (1) 1500W+ output, key down; (2) light weight (30 lbs or less); if the 30lbs is not doable in a single unit, then the power supply could be put in a separate box; (3) capability to support two transceivers, much like the current Yaesu Quadra; and (4) full computer control of amp and transceiver(s) I'll leave the detailed suggestions to those much more qualified than I to make. Finally, I will purchase one at Dayton if it is available, sight unseen, based on the Elecraft history of producing high quality products, and most importantly, updating and supporting them throughout their life cycle. Thanks Elecraft for all that you do.

If I could have anything additional, my first choice would be to have a tuner inside the box, that can either be used or bypassed as necessary. The ability to be run on either 110V or 220V US, ( and European voltages ). Ideally a multi-tap transformer that would allow locations with voltage sag to still operate the amp. For example on my boat I have a multitap isolation transformer that allows voltages to be adjusted to 110V from 90V and up to 250V simply by changing taps. -- John Fritze Jr K2QY k2qy at arrl.net ACACES president 2014 ARES ENY DEC Northern District Hudson Div.

Here's what is important to me. 1500+W (Prefer something built to 2-3K Watts capable and then throttled back... no running on the bleeding edge. Clean.... Like really clean... Separate power supply.... OR AT MINIMUM, the option to choose to use an external power supply so I can choose either the one Elecraft supplies or provide my own.... heavy linear at home and the option for a lighter travel supply. (Ideally, a separate Elecraft PS that obeys the packaging rules... Try to integrate the packaging to fit the K3s, et al footprint... Height being the adjustable dimension to meet volume requirements. Thermal design from the ground up not as an afterthought (patchwork and band-aids not welcome). Seriously consider designing in an easily made mod that will allow other drive profiles for when the current limit is eliminated. Don't want an internal tuner.... want a KAT1500 like external tuner... Long, long list of considered opinions on almost any conceivable spec/feature and a logical argument for/against inclusion in the design....

But having 1200-1500 at 6m would see a potential market in the 6m-eme community for those with ability to pay. 6m-eme is increasing quickly in light of low solar cycles being projected (how WAS/DXCC on 6m is done these days). I am fortunate to have a 1000w surplus Harris TV linear (ch.2) running on 6m, but not all are builder-engineers so ready-to-play would attract quite a few (plus operating down on HF). My most recent Elecraft acquisition was the KXPA100 usable by both my K3/10 and KX3. I have the KXAT100 arriving this week. That is adequate for both home and road activity. If I ever decide that I need HF QRO I will probably build my own LDMOS from several kits available in the market. I still have a 300w 80-10m CCI linear that sits collecting dust after getting the KXPA100. Not sure what is available in LDMOS but a dual KXPA750 might find good acceptance as one could run 750-1500w. I have seen this done on 2m with two 1200w LDMOS run at 750w conservatively to supply a combined output of 1500w (but it is not cheap). I'm going to be roving America during the summer over the new few years with my KX3 + KXPA100 (we pick up the trailer in Seattle in May). 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From km6cq at km6cq.com Fri Mar 17 17:14:43 2017 From: km6cq at km6cq.com (Dan Baker) Date: Fri, 17 Mar 2017 14:14:43 -0700 Subject: [Elecraft] Linear thoughts Message-ID: If you develop a internal or external tuner for it, please include a lock switch.

In the end, after some number of repairs to AT&T cabling, etc, the replacement of a 2Wire 3800 gateway box with a 3801 killed it dead. IF you have a 3800, it will need to be replaced, although the sudden appearance seems to sound like something suddenly gone wrong. Make sure all the little telephone plugs get exercised to clean them up and see if it "suddenly" goes away. In any event back in 2011 I was involved in a very careful staged repair, item by item to see what items made any difference. From my situation and about a dozen parallel similar extended careful replacement exercises, AT&T seems to have it solved and the solution is in their "book". So just let them do their thing. 73 and good luck, Guy K2AV On Fri, Mar 17, 2017 at 3:37 PM, John Saxon via Elecraft < elecraft at mailman.qth.net> wrote: > Off topic, but perhaps others have had the same problem. > I have a K3/100 + ATU (ser#3542), purchased as a kit in 2009.

IF you have a 3800, it will need to be replaced, although the sudden appearance seems to sound like something suddenly gone wrong. Make sure all the little telephone plugs get exercised to clean them up and see if it "suddenly" goes away. In any event back in 2011 I was involved in a very careful staged repair, item by item to see what items made any difference.

At this point of the evolution, this must be seen at the system level, including the (never-to-be ?) "K4" and all other "K-line" components. Why such a broad scope? The present chaining together of control cables is showing its limits. When major features are to be introduced, maximum flexibility is achieved when control signals from A to B don't have to travel through multiple boxes. A client-server approach is appropriate, maybe using Ethernet as backbone. Won't this shut out the owners of non-Elecraft equipment? No, each box will still have a a more conventional control interface. Once a user adds more than one Elecraft box, fast intercommunication between those boxes may provide features not practical if the second box were of a different brand. Key Elecraft philosophies to build on. Value retention. No need to buy a whole new rig to add functionality. Modularity. Today we can add options inside the K3(s). That is great as long as the box is small and light. It is particularly valuable for portable use. Having to bring extra boxes on a camping trip, and deal with the wiring between them, is aggravating. Elecraft put paddles on the KX3 box, and a microphone in the KX2 for a reason. For the home shack adding boxes is necessary to avoid any box becoming too big or heavy. It also is necessary to make possible extensive additions to functionality. A challenge with multiple boxes is to make sure the functional assets in a given box are all available to global applications that depend on resources spread among the boxes. The networking architecture is key for this. High power amplifiers should probably be limited to less than max legal power, but the overall architecture should include the components needed to run more than one such amplifier in parallel. Each amp should be designed to work with a separate controller, and have a minimum of front panel controls. With multiple amp's available one should be able to quickly reallocate those resources between a single or multiple virtual radios. Graphic display resources. We should still have the option for a very compact and portable user interface, such as the K3 without P3. When an upgraded P3 is available, it should be able to display more information than what is the case today. A new display box would make sense for even greater capabilities (higher resolution external display compared to P3, as well as bigger built-in screen options). Could be part of new control console. Central controllers. There should be multiple options. Some people may love to work from a PC screen, and that might also suit the user who starts out with just one box from the new architecture. Others may prefer a special harware console, or working from a slightly upgraded K3 (or K4). 73, Erik K7TV From k9yeq at live.com Fri Mar 17 18:09:26 2017 From: k9yeq at live.com (Bill Johnson) Date: Fri, 17 Mar 2017 22:09:26 +0000 Subject: [Elecraft] Linear thoughts In-Reply-To: <50C9A5C6-0620-4055-8604-DE9A97D47F55@wi.rr.com> References: <006901d29ebe$e1377a90$a3a66fb0$@com> <5941fe74-9de8-fb56-e863-29a3e864c8ef@elecraft.com> <50C9A5C6-0620-4055-8604-DE9A97D47F55@wi.rr.com> Message-ID: I echo that or, offer a combiner second KPA500 to add to the existing!

The safety regulations pertain to the power supply, not the target device. So, it doesn't matter whether the radio has exposed conductive parts. Safety ground on the AC line input is not necessary either, however, design requirements change if you don't have it. The concern is isolation between high voltage line input and low voltage output, and the result of component failures. This specifies clearance & creepage distances, insulation types, rating of capacitors which bridge across line or from line to load, etc. [K9YC: I should say "protective earthing" rather than "ground" so I don't get in trouble for improper use of the term!] The shield (winding or foil) between windings in the transformer is not for safety or necessarily connected to earth. This is for EMI and reduces common mode noise passing from primary to secondaries. An adapter like the KX33 would be flyback topology, so a transformer shield (if present) would be connected back to the primary switching MOSFET's source pin, not ground. Incidentally, the safety regulations are pretty well harmonized between USA and most of Europe. For example, this type of power adapter falls under UL60950 which is identical to IEC60950. 73, Josh W6XU From kd2jip at gmail.com Fri Mar 17 18:36:12 2017 From: kd2jip at gmail.com (Dave Corsello) Date: Fri, 17 Mar 2017 18:36:12 -0400 Subject: [Elecraft] Who sells a small RF quiet solar charge controller? In-Reply-To: References: Message-ID: <6e289c7d-5d8b-374d-7c43-6d29d6ec256a@gmail.com> I use a Genasun GV-5 and a Bioenno Power 4.5 Ah LiFePO4 battery to power my KX2. I agree with Jim. These components work great together--but with one exception: I can't float the battery with the GV-5. When the battery approaches full charge, its internal monitoring disconnects the battery from the circuit, causing the GV-5 to go to open circuit voltage of >= 18 V in full sunlight. According to Elecraft, this would fry my radio. So, as a work around, I use a DPDT switch to keep the solar panel and the load on separate circuits, selectively connecting one or the other to the controller. This way, when the panel is connected and the controller signals an over voltage error (according to Bioenno, this doesn't harm the battery), I know that my battery is fully charged. I then disconnect the panel and connect the load by flipping the switch. I don't mean to hijack Harry's thread--hopefully this post adds value for him. But I wonder if there is any other combination of small, lightweight MPPT controller and LiFePO4 battery that would permit floating the battery.

That's an important part of the difference between models of modems. And, of course, shielding. In the olden days, all telco wiring WAS twisted pair, but far too much parallel conductor cable has come into the system. CAT5 and other cable for wired Ethernet is VERY VERY good at minimizing leakage of the differential signal from wiring, and pickup on that wiring to the differential pair. That's because it is VERY high quality twisted pairs, with many more turns per inch than traditional land line twisted pair. So -- one of my primary recommendations for RFI to/from anything telco, including DSL, is to have telco provide CAT5 or better for the last 1,000 ft or so of the run, and for a greater distance if possible. Note that you may also be hearing your neighbors modems and leakage from their wiring. My second primary recommendation is to apply very good common mode chokes to every cable connected to the modem and to the telco wiring itself. Most of this and a lot more is documented in http://k9yc.com/KillingReceiveNoise.pdf Two other points -- you've already done the right thing by complaining to AT&T, but don't stop there. Contact ARRL's RFI group and get their help in dealing with AT&T. And as others have noted, keep careful notes of all of your contacts with AT&T. 73, Jim K9YC On Fri,3/17/2017 12:37 PM, John Saxon via Elecraft wrote: > If I am reading it correctly, they are saying that the bands that Uverse uses for multiplexing includes 160,80 & 40 frequencies.

Have tuner coexist well with autotuning antennas e.g. StepIR. Automatically switchable to multiple antennas based on band in use. (I've had up to 5 antennas on my 8 position remote switch.) Allow at least two coax connections to the radio (K3) to support diversity reception with remote switching. Low power operation on power limited bands. 220V only is acceptable. Continue the legendary Elecraft usability and integration. i.e. Make it as easy to use as a 100W K3 on CW, digital, and voice.

Just send the RF deck to Elecraft. 2) I like the idea of an optional INTERNAL tuner. Makes it nice and clean for those that need a tuner without a rats nest of Y cables, etc. If there is going to be an external tuner make it weatherproof so you can put it OUTSIDE.

I envision models capable of 500, 750 or 1000 W pep, and it should be possible to combine up to 4 modules for use with any one virtual radio. A virtual radio could be a physica radio like a K3/K3S, or it could be truly virtual, based on an ADC working with signals at on-the-air frequency. In the scenario of multiple amp modules working in parallel, external tuners are mandatory. However an amp module could have space inside for an internal tuner option. There could be a weatherization option that allows such an amp module to be mounted outdoors. Remember, every amp module is built for remote control rather than front panel controls. One amp module using KPA500 technology would cost a little less than an actual KPA500 with its fancy front panel. There would be an upgrade/addon that would make the KPA500 able to play the role of one of the new amp's based on KPA500 technology and capabilities. If you forgive me for the antropomorphic approach, the persona of a "display module" might present itself as follows: " Hi, in my old job I used to be a panadapter. I would be the team member doing everything related to panadapter work, but not much else. Well, recently I have accepted some additional tasks such as transmitter monitoring and user interface for communications. In my new job, I make my hardware resources (display and processing power) available to serve any capability the team wishes to implement, and even multiple simultaneous capabilities." That attitude of serving multiple purposes would exist in other modules as well. 73, Erik K7TV -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Erik Basilier Sent: Friday, March 17, 2017 3:00 PM To: Elecraft at mailman.qth.net Subject: [Elecraft] Linear thoughts To make this an Elecraft amp, it should be designed based on the best architectural ideas from the Elecraft tradition. At this point of the evolution, this must be seen at the system level, including the (never-to-be ?) "K4" and all other "K-line" components. Why such a broad scope? The present chaining together of control cables is showing its limits. When major features are to be introduced, maximum flexibility is achieved when control signals from A to B don't have to travel through multiple boxes. A client-server approach is appropriate, maybe using Ethernet as backbone. Won't this shut out the owners of non-Elecraft equipment? No, each box will still have a a more conventional control interface. Once a user adds more than one Elecraft box, fast intercommunication between those boxes may provide features not practical if the second box were of a different brand. Key Elecraft philosophies to build on. Value retention. No need to buy a whole new rig to add functionality. Modularity. Today we can add options inside the K3(s). That is great as long as the box is small and light. It is particularly valuable for portable use. Having to bring extra boxes on a camping trip, and deal with the wiring between them, is aggravating. Elecraft put paddles on the KX3 box, and a microphone in the KX2 for a reason. For the home shack adding boxes is necessary to avoid any box becoming too big or heavy. It also is necessary to make possible extensive additions to functionality. A challenge with multiple boxes is to make sure the functional assets in a given box are all available to global applications that depend on resources spread among the boxes. The networking architecture is key for this. High power amplifiers should probably be limited to less than max legal power, but the overall architecture should include the components needed to run more than one such amplifier in parallel. Each amp should be designed to work with a separate controller, and have a minimum of front panel controls. With multiple amp's available one should be able to quickly reallocate those resources between a single or multiple virtual radios. Graphic display resources. We should still have the option for a very compact and portable user interface, such as the K3 without P3. When an upgraded P3 is available, it should be able to display more information than what is the case today. A new display box would make sense for even greater capabilities (higher resolution external display compared to P3, as well as bigger built-in screen options). Could be part of new control console. Central controllers. There should be multiple options. Some people may love to work from a PC screen, and that might also suit the user who starts out with just one box from the new architecture. Others may prefer a special harware console, or working from a slightly upgraded K3 (or K4). 73, Erik K7TV ______________________________________________________________ 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 ebasilier at cox.net From al5m at rocketmail.com Fri Mar 17 21:16:12 2017 From: al5m at rocketmail.com (David Rutledge) Date: Sat, 18 Mar 2017 01:16:12 +0000 (UTC) Subject: [Elecraft] Who sells a small RF quiet solar charge controller?

According to Elecraft, this would fry my radio.? So, as a work around, I use a DPDT switch to keep the solar panel and the load on separate circuits, selectively connecting one or the other to the controller.? This way, when the panel is connected and the controller signals an over voltage error (according to Bioenno, this doesn't harm the battery), I know that my battery is fully charged.? I then disconnect the panel and connect the load by flipping the switch.? I don't mean to hijack Harry's thread--hopefully this post adds value for him.?

Full legal limit 160 thru 6m including for JT65 (including 6m for EME ~1minute key down) and RTTY. I like that I don't have to baby the KPA500. 2. Full integration with K3 ala KPA500. Band changing, per band power, etc. 3. KAT1500 built in or separate (doesn't matter). Needed primarily for 80m vertical and 160 inverted L which is likely what almost everyone needs. 160 SWR needs at least 3:1 and preferably 5:1 capability, ditto 80m. I use a single 7/8" hardline to a remote antenna switch. Loss is minimal for 80 and 160. Other bands are served by Steppir or monoband 6m. 4. Must be capable of remote operation as least as good as KPA500, e.g., ON/OFF, status monitoring, fault recovery, fault reporting. I'm sure remoting is in my future in my next QTH choice. 5. QSK. I like being able to hear when the DX is responding and kill my call when I hear it. 6. Most importantly Elecraft quality, service and support! Some thoughts: I really don't care if the PSU is integrated or not but I'd like a profile similar to the KPA500 if possible. I like having the KPA (KAT on top) aside the P3/K3s which sit nicely below my wall mounted monitors. Excellent ergonomics. Making the PSU switchable between 110 and 220 (for NA) and limiting output accordingly would make it possible to serve 1KW and 1.5KW market with a single amp which would be upgradable by running 220 to the shack. Might broaden the appeal. Remote operation is important as we will likely be downsizing and as a result my rig will be at my daughter's house where I will have occasional access for contesting but most of my DXing will be remotely from my house. Great remote operation is a must. 73 jim ab3cv (credit card ready for immediate purchase!)

If you don't need 1500 out, dial it back. You can't push a smaller amp up, but you can throttle a large amp down... there if you need it. Matching automatic tuner with the K3 and KAT 10:1 range (stuff happens, give it room to compensate), built in; more than 3 antenna ports. Consider SO2R modes for contesters (multiple inputs). Enough power supply and transistor overhead to be able to 'comfortably' run at full power on RTTY, or whatever abusive mode is needed. QUIET. Period, quiet. Both to the ears and nearby stations (clean amp) Keep the drive required from the K3 low for a cleaner overall transmission (reduce IMD). The usual Elecraft quality with total integration. I suspect that your main issue will be in keeping the cost competitive.

However, looking back I can see that I have been able to spend a smaller but substantial amount several times. A modular approach to the design would make it possible to get to 500W first, for a price not too different from the KPA500, and then add modules/capability later. This approach also makes more sense for hams in countiries where 1500W or even 1000W is not allowed. Combining lower power modules leads to higher production numbers, which should help reduce per-unit cost. 73, Erik K7TV -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of w7aqk Sent: Friday, March 17, 2017 6:59 PM To: Elecraft Reflector Subject: Re: [Elecraft] Linear thoughts Hi All, I don't really have an oar in this debate, since I am 99.99% sure I won't be buying one--a 1500 watt linear, that is.

Samebody can say me where I can find it? Reading the Elecraft web page I thought, once again, that I am happy to have bought K3S-P3-SP3 - even if the last one, SP3, cost too much :) No other ham radio maker give so wonderful products (by hams for hams) with great manuals, great continuous improving of products for the hams that bought them, great continuous help, with the owners at first line service.

Go to the lower right of your screen. If you have the standard configuration, there will be a system tray. Left click on the "up arrow" to bring up the hidden icons. Right click on the Norton Icon, which is a yellow check mark with a green one within. Click on "Disable Auto Protect". It will give you a protection warning pop-up, and lets you select the duration of disabling the Auto Protect. 15 minutes is generally enough time. Download the file, and install as usual. Norton is a bit aggressive these days.

That means most ham radio applications will be blocked. IMHO, a very poor way to "detect" a virus - it does not have to do any 'detecting' at all. 73, Don W3FPR On 3/18/2017 7:58 AM, James F.

This release offers a bug fix that showed up using DXLab Commander when you switched from a band that did not use the sub-receiver to one that does. There was an excessive delay. In the process, additional performance enhancements were made to the third party virtual radios in Win4K3Suite. > One of the useful features of Win4K3Suite is that it interfaces to all 3rd party logging and digital mode programs such as HRDLogbook, DX Keeper, NAP3, N3FJP, N1MM+, FLDigi, MIXW as well as hardware devices such as the K3/0, the Pig Knob and various antenna tuners.

My input is as follows: (1) 1500W+ output, key down; (2) light weight (30 lbs or less); if the 30lbs is not doable in a single unit, then the power supply could be put in a separate box; (3) capability to support two transceivers, much like the current Yaesu Quadra; and (4) full computer control of amp and transceiver(s) I'll leave the detailed suggestions to those much more qualified than I to make. Finally, I will purchase one at Dayton if it is available, sight unseen, based on the Elecraft history of producing high quality products, and most importantly, updating and supporting them throughout their life cycle.

Use SPE amps as a baseline for features and learning curve. - QSK Preferably PIN diodes - Remote capability like the KPA500 but with more monitoring capability so I can put the amp in the basement alongside the KPA500. - SO2R capability built in - 2 rig inputs - 4-6 antenna outputs programmable and easily switchable - Low distortion LDMOS - single ended or two for push-pull. Max of two MOSFETS. - Switching supply naturally - Optional built-in tuner that can handle at least 3:1. Amp without tuner can handle at least 2:1 SWR without fold back on power. - 1500W key down for digital on 160-6M - Separate or combined amp/PS depends on size and weight. - Amp/tuner tracks K3 receive for pre-tuning. - some form of pre-distortion control to keep the amp clean at full output. 73, N2TK, Tony -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Eric Swartz - WA6HHQ, Elecraft Sent: Friday, March 17, 2017 1:07 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Linear thoughts Interesting discussion.

The original ACOM2000 and ACOM antenna switch had to be used over a "network" for integration with the 2000. The "network" was an unusual one that many people tried to write software to access without success. There were all kinds of issues. It ended up being unusable. KISS would be better. Either ASCII commands, analog voltage inputs or both. Maybe this ACOM2000 situation has changed now. 73 de Brian/K3KO On 3/18/2017 14:54 PM, K9MA wrote: > The capability of switching ATU settings for different antennas, on the > same band, with or without also switching output jacks.

I have SS30 DV and other 30A switching PSUs but they are obviously overkill for this type of rig.

There is a market shift occurring in the full or near qro market. The 2 standouts are the Expert amp line, and the yet to be released Flex/4o3a power genius. One has to ask where the primary market for a full legal limit amp with automation would be. My opinion would be contesters, dxers and remote station users. Others would want such a device but may be less fickle on feature set Things like full qsk, quiet operation, modularity, and over engineering for reliable operation at spec are already something that I think Elecraft would provide as part of their well respected methodology. In order to really be marketable it will need to provide additional value above and beyond expert and flex/4o3a. So again ability to use the 1 amp with 2 radios seamlessly in a rapid SO2R environment would be huge. The flex amp is professing to offer this sans tuner. The expert doesn't quite offer this but has a tuner. Taking the best of both and exceeding that would create a unique market differentiator. If Elecraft could build an amp that could do the SO2R as well as handle high swr tolerance and maintain their usual high standard of construction, performance, reliability and support this would be THE go to amp in the performance ham community IMO. Keeping it as compact, lightweight and quiet as possible is something Elecraft does with all their devices so it's the features that will set it apart. Thanks ~C.

The AV software is ALWAYS going to be 12-24 hours behind the malware writers. If you get bit, the AV software may find it after you update definitions...but it might not. If you get bit by the wrong bug no amount of fiddling with AV definitions is going to remove the infection. Most AV software is mediocre at best when it comes to removing virii/malware. Learn how to remove virii/malware manually and how to re-install operating systems from boot media or archived disk image. Yes...I know...most people don't want to learn these things.

Before calling an amplifier a standout, it must be CLEAN. Based on my measurements, my SPE-1KFA is significantly broader on CW than my KPA500 and Ten Tec 425s. That makes it a poor choice for contesting, where it's broader signal increases QRM to other stations. And how can the 4O3A amp be called a standout when it hasn't yet been tested?

AVG has a free version but you must remember to manually update it daily. I willingly pay for good stuff that works, so I have a paid subscription. Costs about $22/year for each machine.

So leave it out until the other upgrades are installed - there is more "finger room", and there is no other logical reason.

I would add: Modularity should include combinations of power amplifier modules. Once there is more than one amplifier module, one may ask: Does it ever make sense to use them in a way where the output power is not combined? When output is to be fed alternately to different antennas, some switching can be avoided by dedicating amplifier modules to specific antenna lines, but I think fast enough switching capability available that this is not necessary. However, if someone has invested in dual radio capability for running SO2R, might he not someday want to run a contest in 2O2R, dedicating one radio and amplifier module to each operator? Even if only one multiband antenna is available, with a multiplexer it can transmit simultaneously with two transmitters on different bands. Along this line of thinking, the user interface is also to be considered. A control console would be awkward to use by 2 operators, so you would need two consoles. This would be expensive, and using existing K3's as user interfaces would look good. Making small incremental improvements leads to quick success until it backs you into a corner. Flex is showing an ability to take a broader view with their SO2R support. What is missing there is looking beyone SO2R and providing a path forward that doesn't necessitate replacing expensive boxes. 73, Erik K7TV -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Chris Tate - N6WM Sent: Saturday, March 18, 2017 9:22 AM To: elecraft at mailman.qth.net Subject: [Elecraft] Linear Lots of great feedback from all on the Elecraft brain trust. There is a market shift occurring in the full or near qro market. The 2 standouts are the Expert amp line, and the yet to be released Flex/4o3a power genius. One has to ask where the primary market for a full legal limit amp with automation would be. My opinion would be contesters, dxers and remote station users. Others would want such a device but may be less fickle on feature set Things like full qsk, quiet operation, modularity, and over engineering for reliable operation at spec are already something that I think Elecraft would provide as part of their well respected methodology. In order to really be marketable it will need to provide additional value above and beyond expert and flex/4o3a. So again ability to use the 1 amp with 2 radios seamlessly in a rapid SO2R environment would be huge. The flex amp is professing to offer this sans tuner. The expert doesn't quite offer this but has a tuner. Taking the best of both and exceeding that would create a unique market differentiator. If Elecraft could build an amp that could do the SO2R as well as handle high swr tolerance and maintain their usual high standard of construction, performance, reliability and support this would be THE go to amp in the performance ham community IMO. Keeping it as compact, lightweight and quiet as possible is something Elecraft does with all their devices so it's the features that will set it apart.

But it can lead to big boxes that are identified with a pre-conceived use case vision. Other companies have made a good living from selling new generations of such boxes. There will always be a market for that, with customers that can afford it and enjoy the process. Elecraft has given us lower costs, especiall as seen over time, by allowing some separation of boxes. This results in more cables, but the proliferation of cables can be limited by a network design that does more up front than allow for the next incremental feature, in combination with some early planning for needed RF interconnectons.

It's not a question of assigning a "value" to each button to determine which is more important to be visible. Those choices will vary with user anyway. Some users like the band buttons on the KPA500 to change bands on their K-Line. When operating, I can distract myself from DXing or contesting for a few seconds to stare at the front panel of the KPA500 and find the button I'm looking for. I'd rather be able to spot the desired button out of the corner of my eye without losing operation focus. Contrasting button colors support that use case.

Here goes. Oliver, Norton, as well as many other anti-malware programs use different techniques to try to protect you. Some are known anti-virus definitions, or heuristic analysis, or looking to see how many other users of their software have downloaded the particular file you are downloading. Norton will err on the side of caution, and quarantine a file if it does not have a known "reputation" as safe. When you try to open the file, you will get a small warning box in the bottom right of the screen that says it has been removed by Norton. Click on "View Details" within this box. This will bring up another window that shows that it has been quarantined. Within this box, you will see a button that says "More Options"- From here, you can tell Norton to Restore the file. It will then be flagged as OK, and this action will be submitted to Norton. This helps them keep their Reputation checks updated. You can also open Norton directly, and click on "History". In the list that appears, you should see where the file was quarantined. You can also restore it by clicking on that entry in the log.

A separate power supply that can be positioned away from the operating desk would be, IMO, very desirable. An internal tuner option sounds nice. But may be difficult as the components for 1500 watts get kind of big. I think it would be very desirable, but may not be practical unless we are willing to accept a larger box. There have been an awful lot of great suggestions. Most important to me are: 2 inputs, 4 outputs. Inputs are RF sensing. No switch selecting needed to transmit from transceiver A or B. Remembers band, output level, and antenna selection for each input. I think a weather proof tuner is a whole other issue. One I would like to see.

You would have to change the power connector to APP. Now then, if you have any accessories connected to the K3 12 volt output, you may need more current than the Px33 can deliver. I normally recommend a 6 amp supply for K3 users only because they usually have other accessories that are also connected to the power source. The Kx33 is very good about RFI in the ham bands, and with my cautions about adding accessories to the total load, it should serve you and your K3/10 just fine. Maybe you need two of them - one to power the K3/10 and another to power the shack accessories. 73, Don W3FPR On 3/18/2017 11:39 AM, Nick - VE3EY wrote: > I am looking for recommendation about what power supply can I use with > K3s/10 (10 watt only).

Just use Windows Defender. I've used Norton in the past with very mixed results and frustrations. I'm sure it is a well intended product, but it seemed to create a lot of problems for me. I've had similar problems with McAfee. That said, I recently had a very strange issue with Skype, which I use frequently. I have Windows 10, and for whatever reason, the microphone setting kept being reset to "zero" no matter what I did--reloaded software, drivers, etc., no resolution. The microphone works fine on all other programs--just not on Skype. Anyway, on a Skype help blog someone (actually a lot of people) said they had the very same issue, downloaded Malwarebytes, ran that, and it identified some "critters", which when isolated, solved the problem. I decided to do the same, and got a positive result. The problem appears to be solved. Apparently Windows Defender didn't pick up on the problem. So far I've had no problems with Malwarebytes. It scans at night, but is not overly invasive. I know this is "OT", but since we deal with so much software along with our radios, maybe this is helpful--maybe not. I'm not very knowledgeable about all of this software stuff. All I know is that my computer is being bombarded more and more, and it is a full time job to keep it running!!!

In-Reply-To: References: <7d16fef6-1367-b3ae-0a8f-0270ce5551b5@googlemail.com> Message-ID: Before the thread is terminated, I thought I'd toss in my two cents worth. My family and I will be heading to the southern Philippines for several weeks in April. I'll be operating 40-10 meters, CW, SSB, JT65, JT9 QRP with my KX3/PX3 as DU8/W6JHB. My initial plans were to bring a LiFePo4 battery and charger with me. But, with all the other stuff we are taking, including my Canon DSLR and a bunch of lenses, weight became an issue. I decided to use the internal KX3 battery bank when no mains power was available, and when it was, I wanted a lightweight power supply. Something that would run the KX3 and PX3, plus be able to charge those internal batteries. I ordered from Pro Audio Engineering the Kx33 unit. Wow - what great customer service. Ordered it this past Thursday - it was delivered today, Saturday! And, I had mentioned that I was planning on using it in a portable operation. When Howard from PAE heard that I was going to be portable, he surmised (correctly) that I would be using some sort of end fed antenna. He noted that quite often that sort of antenna generated common mode RFI that might cause issues in the power supply, so he tossed in a clamp on mix 31 ferrite to help avoid problems when I'm 7,500 miles from home! This afternoon I hooked up the Kx33 to my rig and gave it a try. I was surprised to see the receive-only voltage showing 14.1 volts on the KX3 display. Nice. I fired up JT9 on 160 meters with the KX3 driving a KXPA100 at 40 watts. The amp was running off a separate power supply, so the Kx33 only had to supply current for a lightly loaded KX3 and PX3, but in that 100% duty cycle mode, the voltage dropped only 100 ma. That impressed me - very nice regulation. Bottom line for me is that this power supply was well worth the money. And the fact that it will run on 110 or 220 makes it an ideal unit for my upcoming vacation, as the Philippines is a 220v country. 73, Jim Jim Bennett / W6JHB Folsom, CA >> On Mar 17, 2017, at 3:13 PM, Josh Fiden wrote: >> >> On 3/17/2017 6:07 AM, Dave B via Elecraft wrote: >> (Often low cost brittle plastic things from >> the Far East.) > These are *all* low cost plastic things from the far east! >> In this case, as the PSU is intended to be used with a device that has >> exposed metallic parts connected to one side of the DC lead, I suspect >> (I admit that I do not know for sure) that the AC input to that PSU >> should include a safety ground, connected to (among other things) the >> transformer inter-winding shield. > The safety regulations pertain to the power supply, not the target device. So, it doesn't matter whether the radio has exposed conductive parts. Safety ground on the AC line input is not necessary either, however, design requirements change if you don't have it. The concern is isolation between high voltage line input and low voltage output, and the result of component failures.

This is for EMI and reduces common mode noise passing from primary to secondaries. An adapter like the KX33 would be flyback topology, so a transformer shield (if present) would be connected back to the primary switching MOSFET's source pin, not ground. > > Incidentally, the safety regulations are pretty well harmonized between USA and most of Europe.

But this is on 6m which I do not believe is restricted to 15-dB gain by the FCC. My understanding that this rule just affected HF amplifiers. In any case it is legally built under FCC rules for television and is modified for use by hams on 6m or higher bands. There is no rule restricting you building a ham amplifier with more than 15-dB (only applies to manufacturers who sell to the public). In fact, I can build such an amplifier and sell it legally to another ham, as long as I am not a business doing multiple sales per year. I built several linear amps for 2m that produced 80w output with as little drive as 50mw. They are biased to draw 8A quiescent current (about 15A at 80w output), so this is near to class-A. I have some 50w linear amps for 3400-MHz that draw full current without drive (obviously class-A) and you do not want to key them long-term in Tx or you risk over heating them. They drive with 5mw. Ed - KL7UW ------------------------------- I believe my Harris analog TV PAs were in the 20 db gain region - apx 10 watts in for a kilowatt out. I believe the digital PAs were lower gain to run as class A (or very close to class A). >From the analog exciter output to IPA to PA to low-pass/filterplexer output it was from 250 mw to 30 kw. That would be over 50 db gain! And that system was type accepted. 73 George - AI4VZ 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From dave at ad6a.com Sun Mar 19 03:37:26 2017 From: dave at ad6a.com (Dave AD6A) Date: Sun, 19 Mar 2017 00:37:26 -0700 Subject: [Elecraft] KX2 pins In-Reply-To: <1489907901.10307.24.camel@anode.ca> References: <1489907901.10307.24.camel@anode.ca> Message-ID: <000201d2a083$a83a03e0$f8ae0ba0$@ad6a.com> Yep! -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Paul Bryan Sent: Sunday, March 19, 2017 12:18 AM To: elecraft at mailman.qth.net Subject: [Elecraft] KX2 pins Does anyone know what the pins exposed on the back of the KX2 are for? ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft at mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to dave at ad6a.com --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus From ebasilier at cox.net Sun Mar 19 04:49:47 2017 From: ebasilier at cox.net (Erik Basilier) Date: Sun, 19 Mar 2017 01:49:47 -0700 Subject: [Elecraft] Linear thoughts In-Reply-To: References: Message-ID: <02e801d2a08d$c3798680$4a6c9380$@cox.net> Now I have the KPA500 and KAT500 actually up and running for the first time. I am very happy with my purchase, and the combo is better integrated than anything else I have used. By integrated, I mean the boxes work together well. The fact that they are separate boxes, that I could purchase at different times, is a big plus for me. However, I have to disagree with those that have said that it all works like having a 500W transceiver. Examples: * Antenna selection now has to be done from the KAT500. I can't do it by the ANT button on the K3, so the labels on the antennas defined there are now useless. * The Power readout is now on the amp, and the Power knob on the K3 just shows the drive power. It is certainly valuable to be able to read the drive power, but in a 500W transceiver that would be a separate readout, and the Power adjustment readout would show the final output power. Again, I am happy, and all is good. But a future Electraft architecture that is to overshadow the competition would use a more global approach to settings that reflect the whole system rather than settings per box, and to achieve this the actual settings in a box (e.g. antenna selection in the tuner) would be controlled through a network rather than local panel controls. The controls would all originate from a controller (or multiple controllers in case of multiple operators operating independently), which could be dedicated devices a la Maestro, or PC's (for cheap users), or hardware transceivers such as the K3. Of course, the K3 would have to get firmware updates that would include more ANT choices, drive power display mode, selection of classic operation mode versus global controller mode, etc. 73, Erik K7TV From z_kevino at hotmail.com Sun Mar 19 06:30:47 2017 From: z_kevino at hotmail.com (kevino z) Date: Sun, 19 Mar 2017 10:30:47 +0000 Subject: [Elecraft] KX2 pins In-Reply-To: <000201d2a083$a83a03e0$f8ae0ba0$@ad6a.com> References: <1489907901.10307.24.camel@anode.ca>, <000201d2a083$a83a03e0$f8ae0ba0$@ad6a.com> Message-ID: I'm assuming some sort of test port.

I, also going to use a terminal routine to look for any sort of ghost ports which I've done in the past.

I had no problem getting FLDIGI to work with my K3s, but it would not work over N1MM. What I finally discovered is that I had to go into N1MM's config tab under hardware and needed to set PTT to on. It makes no sense as I use VOX to do the same thing and it worked with VOX natively. Until I fixed it, I had no problem with using MMTTY as my RTTY interface. Now, I can go back to FLDIGI.

I can't give you a K3S cookbook because I have a KX3, but I can nudge you in the right general direction. If you don't mind using a computer, then ignore the "paddle" methods. Same with the internal encoding/decoding and the utility. Use one of the "sound card" or "modem" programs. DATA A is basically Upper Sideband. Use the built-in sound card. Now, any program that uses a sound card for any digital mode will work. Personally, I like FLDIGI. It does RTTY, PSK-31 (which is popular) and a whole bunch of other modes. If you hit your favorite search engine with K3S FLDIGI you'll get a number of hits, most of them pointed at the Nabble archive of this list. It seems that the biggest problem may be picking one path and following it, I hope my input helps. 73 -- Lynn On 3/19/2017 11:40 AM, Don Pomplun wrote: > > > A few times I've sat down and tried to summarize all this for myself > with no luck, even with Fred's book.

It has a built in sound card that will show up an a USB codec, assuming you're connected to your computer using a USB connection. Whatever you use for your digital software, it should be set for input and output to the USB codec. You will then set the radio to mode: DIGITAL A. The rest is setting the levels according to the radio manual. This is so much simpler than using external, or internal, sound cards and needing additional cables for ins and outs. 73, Barry K3NDM ------ Original Message ------ From: "Don Pomplun" To: elecraft at mailman.qth.net Sent: 3/19/2017 2:40:27 PM Subject: Re: [Elecraft] Help setting up digital >I, too echo my sense of confusion with my K3S and data modes.

I went with MPPT not because of efficiency but because I can still charge when it is cloudy or there is shade on my panels. I have my panels mounted on the top of my van and it keeps my 140 amp hours of batteries charged year round while I use my radio and my 12 volt refrigerator. I have seen some misconceptions about MPPT. The best reason to use MPPT is so that you can put multiple solar panels in series and you will not exceed the maximum input voltage of the controller. The controller will continue to charge even in partial sunlight just as long as the input voltage exceeds the battery charge voltage (in this case 14.xx volts). Since solar panels in series ADD voltage, with two solar panels you get a 24 volts (well, more like 32 volts in full sunlight) and when those panels are in shade, the individual panels may drop down below 12 volts but the sum of the two will be much higher than the required charging voltage. My off grid system in on/in my van runs 24/365 even in the great North West where it is gray for 6 months out of the year!

The following points are directed at soundcard oriented data modes. 1) Use DATA A instead of the normally recommended USB. While USB will work, you normally have the SSB set up for voice, including compression and TX EQ. The data modes automatically turn compression to zero and turn off TX EQ. 2) For RTTY, use AFSK A - that is specifically designed for RTTY and defaults to LSB which is normal for RTTY. 3) Audio levels - ignore the internet advice to adjust the power with the audio level. Adjust the audio to illuminate 4 bars solid on the ALC meter with the 5th bar flashing. This is the "NO ALC" point for these Elecraft transceivers - the first 4 bars are present to allow you to properly adjust the audio. Once adjusted, you should not have to change it unless something changes it in the computer. 4) Output power - adjust the desired power level with the POWER knob. Do not try to adjust the power with the audio level. 5) LINE IN - It is easy to use LINE IN for soundcard data modes than attempting to use the microphone. If you have the K3S or K3 with the KIO3B, you can use the internal soundcard which your computer should recognize as USB CODEC. If using the internal soundcard, do not plug anything into the K3S LINE IN jack, because that will take precedence over the output of the internal soundcard. 6) For a K3 without the KIO3B, you CAN use the computer's built-in soundcard, but you will find an external soundcard will serve you better. (You can use the computer or USB soundcard with the K3S instead of the K3S internal soundcard). The LINE IN and LINE OUT signals are isolated with transformers and no data mode interface is required. That about takes care of the differences between the K3/K3S and other non-Elecraft transceivers. The operation of the data mode software will be the same as for any other transceiver. PSK D and FSK D data modes are there if you want to do other than soundcard oriented data They can encode data entered as CW via the paddles (not from a computer, bug or straight key) The display of decoded text is scrolled on the VFO B display area. The input can also be from the computer as ASCII characters. In the case of FSK D, the FSK keying from a 'one transistor keying circuit' can be applied to the FSK pin on the ACC connector. The hardest part for a newbie to data modes is normally getting the computer software set up and learning to operate it. This is a problem for any transceiver, it is not unique to the Elecraft gear. 73, Don W3FPR On 3/19/2017 2:40 PM, Don Pomplun wrote: > I, too echo my sense of confusion with my K3S and data modes.

You also have to tell the software which soundcard you are using for the data mode audio. For details on that, refer to the documentation of whatever data mode software you have chosen to use. 73, Don W3FPR ------------------------------------------------------------------ Don and Ronnie, Let me see if I can help by pointing out the differences between the Elecraft transceivers K3, K3S, KX2 and KX3 and other transceivers in the use of data modes. The following points are directed at soundcard oriented data modes. 1) Use DATA A instead of the normally recommended USB. While USB will work, you normally have the SSB set up for voice, including compression and TX EQ. The data modes automatically turn compression to zero and turn off TX EQ. 2) For RTTY, use AFSK A - that is specifically designed for RTTY and defaults to LSB which is normal for RTTY. 3) Audio levels - ignore the internet advice to adjust the power with the audio level. Adjust the audio to illuminate 4 bars solid on the ALC meter with the 5th bar flashing. This is the "NO ALC" point for these Elecraft transceivers - the first 4 bars are present to allow you to properly adjust the audio. Once adjusted, you should not have to change it unless something changes it in the computer. 4) Output power - adjust the desired power level with the POWER knob. Do not try to adjust the power with the audio level. 5) LINE IN - It is easy to use LINE IN for soundcard data modes than attempting to use the microphone. If you have the K3S or K3 with the KIO3B, you can use the internal soundcard which your computer should recognize as USB CODEC. If using the internal soundcard, do not plug anything into the K3S LINE IN jack, because that will take precedence over the output of the internal soundcard. 6) For a K3 without the KIO3B, you CAN use the computer's built-in soundcard, but you will find an external soundcard will serve you better.

That about takes care of the differences between the K3/K3S and other non-Elecraft transceivers. The operation of the data mode software will be the same as for any other transceiver. PSK D and FSK D data modes are there if you want to do other than soundcard oriented data They can encode data entered as CW via the paddles (not from a computer, bug or straight key) The display of decoded text is scrolled on the VFO B display area. The input can also be from the computer as ASCII characters. In the case of FSK D, the FSK keying from a 'one transistor keying circuit' can be applied to the FSK pin on the ACC connector.

If using one of those, stay in DATA A submode for RTTY. But do follow the instructions in the documentation for the software you are using. Most DATA modes (other than RTTY) will operate from a waterfall display where you click on a signal of interest and that signal is decoded. The bandwidth controls on the receiver would normally be set wide to see a wide waterfall with many signals. Most using RTTY prefer MMTTY which would normally be used with AFSK A sub-mode on the K3/K3S (LSB on other transceivers). You would normally tune to the RTTY signal with the VFO knob, and operate with a narrow bandwidth. 73, Don W3FPR On 3/19/2017 4:23 PM, Lynn W.

Traditionally, a teletype Terminal Unit (TU) generates two tones: "mark" at 2125 Hz and "space" at 2295 (170 Hz shift -- other shifts are possible, but this is the main one). Put a (clean) 2125 Hz tone into a SSB transmitter on Lower Sideband and you'll get a carrier 2125 Hz below the VFO setting. To transmit "mark" on 14.070 you'd dial the VFO to 14.072125. The space signal would be 170 Hz lower (because LSB inverts) and "low space means fine teletype." For teletype, the mark and space tones are generally pretty exact, and you're going to tune the VFO. For PSK and the like, you'll have a waterfall display showing a number of different QSOs, and generally speaking, you click your mouse on the one you want. The software shifts the tone(s) as needed and the VFO stays locked. Everyone on PSK-31 is pretty much within 2 KHz of each other. 73 -- Lynn On 3/19/2017 1:44 PM, Don Wilhelm wrote: > Some data mode applications will do RTTY in USB by inverting the > mark/space.

So one should be cautious of that or ALWAYS use the same tones. I've made that a non-issue for RTTY by using FSK but in PSK (sideband doesn't matter) or others, the same issue remains.

To answer this question if you do not have an additional USB Serial to 3.5mm plug, you could just take a regular USB to serial, attach a serial cable, cut the cable and determine the ground, transmit and receive wires, and then wire them up to a 3.5mm plug. Check out the pin outs in the KPA500 manuals. The biggest pain here if you do not have a spare USB Serial to 3.5mm, then you have to wait for a replacement before you know. At least this way you can find out sooner which device is at fault. 73 Tom va2fsq.com -----Original Message----- From: Nr4c Sent: Sunday, March 19, 2017 11:27 PM To: john at kk9a.com Cc: elecraft at mailman.qth.net Subject: Re: [Elecraft] kat500 can't be seen by kat500 utility That is the serial port.

The PTT would enable, it was not in TEST mode, the CW monitor would sound, but no output. Pushing the TUNE button would result in "0 watts" showing on the display.

Yes the KPA500 can be used very easily with other transceivers, but it's probably best with Elecraft transceivers. "Like having a 500 watt transceiver" or 1500 w going forward. I have used the KPA500 with a TS590S on a trip to V4 and it is very nice, but not with all the ease of use I would have had with a K3. So far as overall architecture i.e. separate power supply, etc, I think this depends on the nature of other future companion products for such an amp. Those of us outside Elecraft have not seen these yet, so our speculations are only in the context of existing products. Many of these decisions are probably already made by those at Elecraft with this knowledge. I suggest that Elecraft has a history of introducing products which do not obsolete their existing products, but rather expand their line into new niches of the market. It is reasonable to assume that they will continue to do this. Based on this assumption, while the K3/KPA500 products are nice on the operating desk at home, they are also easily transported (ideal for DXpeditions), a new line of K products might be a bit larger with primary focus on the operating desk and more advanced built-in displays. With the existing K3 line in place they would not necessarily need to be very portable. A companion higher power linear might have a bit more room inside for larger PS and/or auto tuner. Looking at an autotuner vs. built-in PS, I currently operate a K3S with an SPE 1.3K-FA amp. It comes close to the high power transceiver concept, except due to the unique ALC Elecraft approach, I can't rely on the usual SPE's ability to use the ALC to throttle back transceiver drive levels. Its easy to set drive levels manually with K3 so no big problem. I just have to remember to do it. It would be nice to have this capability just like the KPA500 provides. The SPE is a nice small amp not much larger than a KPA500 and includes an antenna tuner and PS. However, like most built-in tuners, it gives up some capability. It does not like to deal with mis-matches over about 4:1. Considering that this is at about the 1500w level, this limit is understandable in the size of the amp. I try to keep my antenna SWRs within this constraint. I also have the autotune option in my K3S which, unlike most built-in tuners, deals nicely with SWRs of up to 10:1, but of course at the 100w level. Given the choice of a built-in high power autotuner able to deal with SWRs in say the 6 or 7:1 range vs built-in PS, I would remote the PS. If a 10:1 tuner was offered but in a larger package, I would remote everything except a control head for the amp and tuner. Not a long distance maybe of to 10 ft. Having a separate KAT1500 auto tuner in the line is another possibility, but it would have to have some features over the Palstar HF- Auto or Kessler AT- Auto. 73, Dave, K1KA David Mackey K1KA at comcast.net From w0fm at swbell.net Mon Mar 20 10:57:20 2017 From: w0fm at swbell.net (Terry Schieler) Date: Mon, 20 Mar 2017 09:57:20 -0500 Subject: [Elecraft] Help setting up digital In-Reply-To: <79cc24d1-9024-bcd2-c0cc-c80147c00f2c@embarqmail.com> References: <83889D8978E64C6EAB8856A371DAC80F@MININTMC1HLDC> <79cc24d1-9024-bcd2-c0cc-c80147c00f2c@embarqmail.com> Message-ID: <00ef01d2a18a$46db1f50$d4915df0$@swbell.net> Don wrote, <"3) Audio levels - ignore the internet advice to adjust the power with the audio level.

The following points are directed at soundcard oriented data modes. 1) Use DATA A instead of the normally recommended USB. While USB will work, you normally have the SSB set up for voice, including compression and TX EQ. The data modes automatically turn compression to zero and turn off TX EQ. 2) For RTTY, use AFSK A - that is specifically designed for RTTY and defaults to LSB which is normal for RTTY. 3) Audio levels - ignore the internet advice to adjust the power with the audio level.

I have had similar problems at Field Day, and some friends of mine have also had issues while in mobile contest use. From what I can tell, the K3 can be very sensitive to power voltage levels. If there is any issue with the power supply itself, or if the cables between the power supply are too long or not of sufficient gauge, power levels can drop at the K3 and can lead to problems including no or limited transmit power. As an example, I have an Astron power supply mediated through a PWRgate device and a separate power distribution panel. When I route my K3 power this way, I can see a drop of as much as one volt or more of input voltage according to the K3's internal voltage meter when I transmit. On the other hand, using a short run of thick gauge wire direct from the PS to the K3, the voltage drop is only .1 or.2 volts. My friend had problems in mobile use in a contest going from the vehicle generator (motor on) to car battery. He ended up installing a voltage booster device to get solid performance. When this happens I was able to restore function by reinstalling firmware and recalibrating the transmit power.

I'd like the KPA-1500 designed for 2kw so it will easily make 1,500 watts in "run" mode all weekend long on all modes, including RTTY. Too many of today's "legal power amps" often won't make legal power. A quiet Amp is important, use 4" or larger cooling fans and not tiny 2" fans like many solid-state amps use as they often need to run at warp speed and then make a tremendous amount of noise. I'd like two radio inputs and six antenna outputs, and to be able to adjust the brightness of all front panel light from bright to very dim. The KAT-500 front panel lights cannot be turned down low enough for me. The KPA-500 is small and excellent for DXpeditions, build the KPA-1500 as a robust legal limit amp with large heat sinks that will run cool, operate quietly, and easily make 1,500 watts on all bands 160-6m and I'll be sure to buy one. 73, Dick- K9OM From k6sdw at hotmail.com Mon Mar 20 13:17:14 2017 From: k6sdw at hotmail.com (Eddy Avila) Date: Mon, 20 Mar 2017 17:17:14 +0000 Subject: [Elecraft] KX3 heatsink question Message-ID: With some expert help from the Elecraft forum, I'm up and running JT65/9 using my new KX3.....

I made my adapter years ago when the KAT500 arrived in my shack for beta test. It may have been nothing more than designating the RS232 functions assigned to tip and sleeve. Or maybe I had to ask someone. In the past, pin assignments for all connectors was in the manual. It's very disappointing to see this practice discontinued. It has the effect of turning hams more into appliance operators. Looking at the XG3 manual, the 3.5mm ring is wired to pin 2 of the DB9 female, the tip to pin 3, and the sleeve to pin 5. Pin 8 is jumpered to pin 4. My adapter does not include that jumper. 73, Jim K9YC On Mon,3/20/2017 9:47 AM, Don Wilhelm wrote: > Jim, > The only place I have seen the DB9 to 3.5mm wiring is in the XG3 manual. > It is not in the KX3 or KX2 manuals. > > 73, > Don W3FPR > > On 3/20/2017 12:20 PM, Jim Brown wrote: >> On Mon,3/20/2017 3:50 AM, john at kk9a.com wrote: >>> Yes but almost all serial cables have DB9 connectors.

However if you are using data modes with long transmit periods at power levels above 7 or 8 watts, you might want to consider an aftermarket heatsink. Give it a try and feel the heatsink after several transmission periods. It will be warm, but you should be able to hold your hand on the heatsink without discomfort. That is always a good test for OK vs. Too Hot. 73, Don W3FPR On 3/20/2017 1:17 PM, Eddy Avila wrote: > With some expert help from the Elecraft forum, I'm up and running JT65/9 using my new KX3..... > > > My rig's s/n is 9403, do I still need to consider upgrading to the after-market heatsink or the one that came with my new KX3 (9403) sufficient for most data modes? > From efortner at ctc.net Mon Mar 20 15:06:17 2017 From: efortner at ctc.net (efortner) Date: Mon, 20 Mar 2017 15:06:17 -0400 Subject: [Elecraft] test Message-ID: <001101d2a1ad$0debb150$29c313f0$@net> Test no reply needed.

Looking at http://wa8lmf.net/APRS_PSK63/index.htm#Background and am not sure if the configuration below will work. "As a dual-port send/receive terminal. The first port is the PSK/GMSK/FMSK sound card mode. The second port can be any of a variety of external hardware- or software-based TNCs on either 1200 baud VHF or 300 baud HF. For example, a classic command-line hardware TNC (i.e. TNC2, KPC3, etc), a KISS-interface hardware TNC (i.e. TNC-X, TinyTrack4, Tracker2, etc), or another (separate) sound card software TNC. The program directly supports the KB2SCS 300/1200 baud soundcard soft TNC, the AGW Packet Engine and the new UZ7HO "Soundmodem". Currently (as of APRS Messenger Ver 3.27) the latter two are supported on receive-only. Full transmit/receive capability will be provided sometime in the near future in an updated release of APRS Messenger." -- View this message in context: http://elecraft.365791.n2.nabble.com/KX2-30m-APRS-tp7628063p7628347.html Sent from the Elecraft mailing list archive at Nabble.com.

I initially thought that the poster could not achieve 4 bars or 5 bars on the ALC meter. But after several emails, I realized that he was skipping from 3 bars to 5 bars with slight changes in the LINE IN gain. Normally, I recommend that the soundcard sliders be set to 50 to 75% of full scale, but that is actually soundcard dependent - and may be Mac and Windows dependent as well. Perhaps a better statement is to set the K3S (or K3) LINE IN gain for about mid-scale and then adjust the soundcard sliders to produce the 4 ALC bars with the 5th one flashing. Final fine adjustments can then be made with the K3S LINE IN gain which will have a finer resolution at mid-scale than at extremely low or high settings. 73, Don W3FPR On 3/20/2017 7:45 PM, Bill Frantz wrote: > I had exactly this problem with my K3 and Mac.

The import with the rounded fin root as well as others have a less optimum volume to surface area ratio and stay much hotter between transmit cycles. Also a good heatsink will allow higher power operation in temperatures we sometimes find ourselves when operating on picnic tables and the like in the summer! (commercial content) We find most of our customers who are occasional digital users are satisfied with the smaller of our two heatsinks, model Kx31, but the JT mode enthusiasts, especially contesters are going for the slightly larger Kx32 model. Much more info on our website.

I have been planning the layout of the station and the thought came that if I stack the K3 at the bottom, with the KAT400 on top of the K3 with the KPA500, it would solve the space issue. It rasises questions about : 1. Would the K3 support the stack? 2. Will I be having heat issues. I use RTTY (FSK) quite a bit and noticed that the K3 PA temp is about 45 to 47C when driving the KPA500 full 500 watts. There may be other issues, but at this time, I think the major ones would be weight and heat.

The import with the rounded fin root as well as others have a less optimum volume to surface area ratio and stay much hotter between transmit cycles. Also a good heatsink will allow higher power operation in temperatures we sometimes find ourselves when operating on picnic tables and the like in the summer! (commercial content) We find most of our customers who are occasional digital users are satisfied with the smaller of our two heatsinks, model Kx31, but the JT mode enthusiasts, especially contesters are going for the slightly larger Kx32 model. Much more info on our website.

But what a tangled mess of cables! Using PVC is a great idea but I wonder if it is stiff enough not to sway under the weight of the equipment. It doesn?t show but did you add some cross members to strengthen the frame? Maybe its about time for Elecraft to work on something to integrate their K3 related components without the need for so many interconnecting cables.

I usually run about 8 watts and do monitor the final amplifier temperature via the screen display. It never gets anywhere near the shut-down level or "hot" to the touch. I do live in Seattle so the ambient temperature in the shack seldom exceeds 80F and is mostly around the 68F furnace setting and also the typical spring summer fall 60-75 daytime temperature here in the land of eternal rain 9 months of the year and drought with sunny mild temperatures for the other three.

Message-ID: Okay, here's an odd one and I couldn't find any suggestions in the archives or using Google-fu. I can run any mode with my KX3/PX3/KXPA100 station with no incident except for JT modes; using WSJT-X, I will complete a Tx cycle and randomly the KX3 will bounce (power off/power on.) 9 times out of 10, I'm operating at 3W. I'll sometimes bump to 5. To test this, I have also bumped it to 11 watts to kick the amp in and I get the same reaction; that is, sometimes (but not always) the station just decides it's had enough and the power bounces. Power supply is a Samlex SEC-1223. ALC is within tolerance, MIC BTN is off, it's operating in DATA A and VOX is set on. I'm kind of running out of things to try. Any thoughts? BTW, I am getting out there; PSKReporter shows activity so I'm putting the fire in the wire.

You may have a failed power jack. Early KX3s did not have the power jack glued to the board and could fail (even with the right angle power plug). The failure would be intermittent.

There is natural interaction between the K3S level (mic) control and the sound card level but it's a hair triggered operation to get the ALC set.... and regrettably the VOX and Anti-VOX gains are along for the ride. Get the latter set for RTTY and they can be off on SSB because the "experts" think that the VOX takeoff point should be after the mic gain control.

I spent the past weekend trying to get my K3S set up for RTTY with MMTTY. My old K3 (474) worked just fine for years. Using Data A, AFSK, 45 baud, I can cleanly copy RTTY and Transmit via VOX, but, for the life of me, I cannot get the ALC set to "4 bars solid with the 5th bar flashing". I can get it to set to 3 bars solid or 5 bars solid but nothing in between, no matter how sensitive I try to be. Seems I recall someone else with this exact issue on her a few weeks ago. I have spent this morning trying to find that post as I'm pretty sure his problem was solved. I am setting the ALC via the Mic (Line) Gain.

It contains the new encoder, a new knob and several other components as well as the encoder board. If this is your only option, be aware that the spacing between the new encoder board and the back of the Control Board is critical. You must flush trim the leads on the Control Board where it can contact the encoder board and also flush trim the encoder board after it is assembled. Flush trimming means really flush - diagonal cutters are not sufficient. You will also have to enlarge the hole for the encoder in the Front Panel metalwork a bit. A knife run around the hole a couple times will allow the encoder shaft adequate clearance. You might want to put a piece of "fish paper" between the encoder board and the Control Board. 73, Don W3FPR On 3/22/2017 5:59 PM, Bob G3PJT wrote: > Hi > > I need a main tuning encoder of a K2.

I have tried it out on the N1MM+ logger with no success. It does control the VFO, the band/mode change but no sending CW from the logger nor switchin PTT. My K3 which has the menu item for the DTR/RTS configuration is doing it all perfectly under the same logger configuration. Is there any other way to get CW/PTT control on KX2 from the N1MM+ logger?

Must have read it over two or three times before it actually sunk in what it was saying. "For the logging function you can use JT-Alert but you have to stop the automatic update to HRD. You can't run HRD. *Every fourth or fifth "CQ" my KX3 will power cycle if running with HRD.*" (Emphasis mine.) So, I'm now wondiering if there is some interaction that I need to pay attention to between this software and my hardware. And obviously, someone mentioned this already. These are not my words. The obvious question is, whose words are they?? Normally, a clip from Evernote adds the URL into the properties for the note. But this note is one that I created, curated from my wanderings throughout the Intertubes for how to do this, and it contains private communications, Facebook comments, replies to messages and other things that don't appear to be attributed at all. In short, despite my Google-fu I can't get a real source for the issue no matter how creatively I search. Since this statement seems to fit the behavior I'm experiencing (no matter if low or high power; only on JT modes) I'm going to take HRD out of the loop and see if this problem goes away. If so, so much the better. I like HRD, but not to the level of letting it bounce my KX3 while in use. To satisfy my curiosity, I'll also monitor internal temperatures while operating but I seriously doubt that they are the issue. Stand by, I may have an answer shortly.

I did know about the new encoder kit but the problem is that of its cost when it gets here. Elecraft quote 124USD for the kit, that's ?100 here which then gets VAT at 20% and a local handling charge - say a total of ?130-140 and as well if I read things correctly I will need to get a new knob. So you can see that my problem is that unless I can get a cheaper replacement I might as well sell the K2/100 either in bits for spares or at a discount. The encoder does work fine but it has suffered a knock which has made it slightly stiff to turn, i.e it wont 'spin', but it is useable.

Understanding the principals of this scrip writing I can create my own macros as I want them to, the CW comes smoothly to the KX2 and is transmitted to the air provided the VOX button is on. The only change- the ESC button doesn't work any more for stopping the TX but the F11 takes the job over! I recommend this method to all KX2 owners, thanks to this very knowledgable Elecrafters community! 73 de Linas LY2H On 2017 kov. 23, kt at 03:01 Chris Tate - N6WM wrote: > Yes > Try these-- credit to K4MTX these work on the KX2 as well. > > https://k4mtx.wordpress.com/2013/06/02/kx3-how-to-configure-n1mm-to-use-function-keys-to-send-cw-without-additional-cables-or-hardware-like-winkeyer/ > > F1 Cq,{CATA1ASC KY cqtest * *;} > F2 Snt,{CATA1ASC KY 5nn # #;} > F3 Tu,{CATA1ASC KY tu;} > F4 {MYCALL},{CATA1ASC KY *;} > F5 His Call,{CATA1ASC KY {call} ;} > F6 Repeat, {CATA1ASC KY # #;} > F7 Exch, {CATA1ASC KY #;} > F8 Agn?,{CATA1ASC KY agn? ;} > F9 Nr?,{CATA1ASC KY nr? ;} > F10 Call?,{CATA1ASC KY cl? ;} > F11 Break,{CATA1ASC RX;} > F12 Wipe,{WIPE} > > > -----Original Message----- > From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of > Irma & Linas(LY2H) > Sent: Wednesday, March 22, 2017 5:08 PM > To: Elecraft at mailman.qth.net > Subject: [Elecraft] KX2 on N1MM+ > > Hello group, > > Is it correct that KX2 does not support the CW/PTT operation through the > DTR/RTS ports?

You would need an antenna connected to an audio transducer (speaker or 'phones) to hear it. (Perhaps one would call it a non-conversion receiver.) An audio amplifier helps, but you have to deal with the 120 Hz buzz caused by the 60 Hz power line fields all around. A high pass filter with a cutoff above 150 Hz helps a great deal. Listening to the variety of squeaks, chirps and other noises produced by electronic discharges all over the planet is a fascinating hobby in itself. They are commonly referred to as 'Sferics, short for atmospherics. 73 Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of thelastdb Sent: Thursday, March 23, 2017 6:57 AM To: Ken G Kopp; wa9fvp; elecraft at mailman.qth.net Subject: Re: [Elecraft] K3S ELF 10KHz Wait a second, there's a big difference between a sound pressure wave and an electromagnetic wave at 10-kHz...

What is being transmitted is an electromagnetic field, NOT a sound field. Sound is AIR (or water) vibrating. Sound waves travel a bit faster than a foot per msec. Sonar uses sound. The system Mike is talking about is radio. Radio is an electromagnetic field, which the simultaneous existence of an electric field and a magnetic field at right angles to each other, and they move through space at the speed of light. We can't hear radio waves, but we could hear high frequency sound waves if the radio waves were somehow detected (the trusty non-linear junction) and caused something to vibrate (or even to arc). 73, Jim K9YC On Thu,3/23/2017 3:03 PM, Mike Morrow wrote: > I didn't understand the reference to audio either. > > When I on the crew of a US ballistic missile submarine more than 40 years ago, our main communications receivers were AN/BRR-3 units whose full frequency range was only 14 to 30 kHz.

That should be the VLF/LF/MF RAK (15 TO 600 KHz), not the RAL, which was the MF/HF companion receiver (300 to 23000 kHz). These 80-year-old-design TRF/Regenerative units were outstanding receivers during their era as the US Navy's principal shipboard set before and during WWII. The RAL still does well today on HF, especially for CW. http://www.virhistory.com/navy/rcvrs/rak-ral.htm This whole thread was mis-named. The specified frequency of 10 kHz is far far far from ELF. Tbat is merely a Very Low Frequency VLF, 3 to 30 kHz. Ultra Low Frequency ULF is 0.3 to 3 kHz. Super Low Frequency SLF is 30 to 300 Hz. Extremely Low Frequency ELF is 3 to 30 Hz.

There's obviously no technical/engineering reason that would prevent Elecraft from fielding something of this nature on the market. The real issue is ... would it be profitable.

I don't know if it is still active. The antenna is [was] a linear series of vertical elements down a valley, suspended by cables from the mountains on each side. I believe there were ten total, fed in two groups of 5 from two transmission lines on the valley floor. The suspension cables provided capacitive top loading, most of the radiation came from the vertical elements. Similar to the antenna at SAQ. Not much to listen to, it was [or still is] extreme QRSS. Just a handful of characters, often only one or two. The Omega system operated down in the 10-15 KHz range. The NA station was in one of the Dakotas, but it's been decommissioned for several decades. It wasn't much to listen to either. WWVL was on 20 KHz for awhile, gone now, and not much to listen to when it was on. I've "heard" WWVB on 60 KHz, pretty dull. At frequencies below 20 KHz, you don't need tubes or transistors, just a generator with a lot of poles and high RPM. Before LORAN-C on 100 KHz died, at least one of the stations was outfitted with an Accufix transmitter from Megapulse Corp. This was a late 20th Century re-incarnation of the spark gap TX ... SCR's for the spark gap, huge capacitor banks, around a megawatt, and precise timing from a room full of electronics. What goes around sometimes comes around. 73, Fred ("Skip") K6DGW Sparks NV USA Washoe County DM09dn On 3/23/2017 3:45 PM, Ron D'Eau Claire wrote: > The Jim Creek antenna facility is amazing - a series of over mile long wires > (cables) for the radiator strung from mountain to mountain across a valley > being fed with IIRC a megawatt of VLF RF. > > 73, Ron AC7AC > From z_kevino at hotmail.com Thu Mar 23 20:41:04 2017 From: z_kevino at hotmail.com (kevino z) Date: Fri, 24 Mar 2017 00:41:04 +0000 Subject: [Elecraft] [KX2] paddle always keys Message-ID: On my KX3, when I have the onboard KXPD3 connected and am in SSB mode, the paddle will not send out CW.

I don?t recall this ever happening with my K3 but when I launch windows 7 on my PC, the K3S, USB Audio CODEC is turned off. It?s shown in the Volume Mixer and when I double click on the Icon, it launches the properties for the CODEC. I can click on the Levels tab and set the Microphone level. When I click on the speaker Icon, the sound is on and I can adjust the level. Here?s what gets weird. After the few or even several seconds, the sound goes off and the speaker icon shows the circle with a slash. The microphone level also moves to zero. I have the volume mixer stretched halfway across the bottom of the monitor and I noticed that other sound devices are shown. At least 3 or 4 pop up and they all have level controls and a speaker icon. If I move a slider up, it pops back down. If I click on the speaker Icon nothing happens. For some reason the they hijacked all of the legitimate record devices and turned them off. Now this is really weird. If I launch Task Manager, for a few seconds under the processes tab, I can see several copies Regsvr32.exe, then they disappear. I can go back the K3S CODEC and turn it back on. Everything is OK but after a few or even several minutes the Regsvr32.exe processes are back and the sound goes off. Several copies of the bogus audio devices are back and if I kill Task Manager and launch it again, Regsvr32.exe and the bogus sound devices are gone, for several minutes and the process repeats. I normally run Norton Internet security and do scans periodically but I never had a virus.

If you want to see the match the KAT500 gives you (should be very good when tuned), then put it between the KPA500 and the KAT500. On the other hand, if you want to see what the antenna itself is showing, then add the sensor on the output port of the KAT500 to the antenna. Remember, the W2 only can have two sensors attached, and the KAT500 can switch three antennas, so you need to choose how many antennas you wish to monitor and have that many (again, max of two) sensors connected to the W2. I generally like to monitor the antennas, so my W2 sensors are connected between the KAt500 and the antennas. I also have another sensor connected between the KPA500 and the KAT500, but this one is connected to my P3 so I can view the output waveform as well as monitor transmitted power. This one normally shows a great SWR, although at times I will switch the KAT500 to bypass mode so I can take a look at the real antenna match (and appreciate the work of the KAT500). Hope this helps - If you have any W2 questions I?ll try to answer them. 73, Jack Brindle, W6FB Elecraft Engineering > > On Mar 23, 2017, at 9:21 PM, Lane wrote: > > I've disconnected the majority of cables from my station and wished I > had marked a few of them before doing so.

So simply take the features and functions of the KPA500 and increase output to 1500W PEP. I'd not like to see Elecraft waste their time with an Spurious/IMD spec that only just pass the FCC requirements, it's about time someone showed leadership here. At the very least I'd expect to see Spurious emissions 60dB (or more) below PEP and IMD 30dB (or more) below PEP across all bands, I'll admit this is not easy to do from 1.8-50MHz but it's also not impossible. This is the minimum commercial spec for 1kW HF gear here in VK already, for inspiration Codan 3062 or LINEARamp Gemini. However it's not easy especially since the FCC ties your hands behind your backs in terms of gain from the get go. The nice to haves (wish list) would be; - Four antenna output with an internal tuner that could flatten antennas that creep up towards 3:1 at the band edges (ala alpha 9500 series) - Limit the weight of the KPA1500 to the same as the KPA500 is now (preferably lighter) so switchmode PSU's this time please. - Make allowances for those countries that aren't limited to FCC 13dB gain, we'd be happy with just 16dB (*30-40W grin*) and let us pocket the IMD/Spurious improvements If Elecraft were to make such an amp with this sort of spectral purity I'd be inclined to complete the necessary paperwork for a high power variation on my license here in VK and purchase an amp. I've toyed with the Gemini Amp a couple of times but the integration of the KPA500 eventually tipped the balance. Then all we've got to do is get more people pointing their beams at us during DXpeditions and Contests and we'd be set. 73 Matthew VK5ZM On 18 March 2017 at 03:36, Eric Swartz - WA6HHQ, Elecraft wrote: > Interesting discussion. > > Folks, if we did introduce a 1500 W solid state amp similar to our KPA500 > in operation, what features etc would be important? > > 73, > Eric > /elecraft.com/ > > > > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft at mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: http://www.qsl.net/donate.html > Message delivered to vk5zm at bistre.net > From w0mu at w0mu.com Fri Mar 24 02:06:45 2017 From: w0mu at w0mu.com (W0MU Mike Fatchett) Date: Fri, 24 Mar 2017 00:06:45 -0600 Subject: [Elecraft] Linear thoughts In-Reply-To: References: <006901d29ebe$e1377a90$a3a66fb0$@com> <5941fe74-9de8-fb56-e863-29a3e864c8ef@elecraft.com> Message-ID: I think the FCC is going to change the rules on the gain factor, hopefully soon. 1500w out on RTTY with zero limitations on duty cycle or very little limitation. Very quiet cooling. 6m would be nice but probably an issue at that power. Price is probably the biggest what if. No tune obviously. Built in tuner. If you can make the amp like 3:1 SWR's great then no tuner. I would love to be able to share the amp with my 2nd K3. SO2R or similar type operations. I would be ok with a separate power supply separate from the amp part to keep the size as small as possible. Fully remote controllable with USB/Ethernet including an on off function or reset.

Also, configuration files are saved by the serial number, so you cannot "clone" one from the other - I understand this can be circumvented (have not tried to do that), but is not recommended. In addition, the calibration data that is included in the configuration file will not be the same for both - that is unique to the particular K3/K3S. When you get your K3 and K3S back from Elecraft, save a configuration file for each of them. Both your K3 and K3S will be set to factory defaults when you get them back. Set any desired menu parameters (such as AGC Threshold and Slope among others) for your personal preferences - then save a configuration file again. That way you can always restore to factory defaults, or restore to your personal settings by restoring the configuration file. Also if you ever need to do an EEINIT to solve a problem, you will have the configuration file with your preferred settings, and complete recovery will be quick and easy.

I would like to see it be capable of running 1500 watts out continuous duty on RTTY with all components conservatively rated. I really like the idea of having the antenna switch built in for remote capability -- switching to different antennas with port memory for each band -- 6 ports would be great. Band switching can either follow the K3/K3S or be "RF sensed". Of course the amp should be designed for full QSK and have protection from high SWR, overdrive, etc. I like the feature on my KPA500 that provides saving the drive level by band (using the K3 or K3S). An internal antenna tuner is not necessary. It would also be nice to have an Elecraft developed program to use for remote operation. Sure hope you do it, Eric. Put me on the list to buy one. 73, Greg-N4CC From ken at arcomcontrollers.com Fri Mar 24 13:43:25 2017 From: ken at arcomcontrollers.com (Ken Arck) Date: Fri, 24 Mar 2017 10:43:25 -0700 Subject: [Elecraft] FS: K3/100 + P3 In-Reply-To: <01D7DEB5-DA5D-4017-8588-46F7443B666A@mac.com> References: <1484D9CB-9F26-4EB0-8621-FD70FB29D6F8@mac.com> <01D7DEB5-DA5D-4017-8588-46F7443B666A@mac.com> Message-ID: I would be interested in the P3.

In-Reply-To: References: Message-ID: I figure I'll wrap this issue up and give it a decent burial. I reconfigured WSJT-X and JT-Alert to NOT use the HRD interface, but natively communicate with the KX3. I then fired up the rig and began calling CQ with the power down to 3 watts. The bands being as "wonderful" as they are, I didn't expect much on 20M during the middle of the day with the noise floor here at S9 but PSKreporter had me going into Europe the way I used to within a few minutes, and I did actually make a QSO after about 10 minutes (that's about twice as long as it lasted previously before a reboot). I believe the problem is fixed. The KX3 didn't even get above ambient temperature. Now to figure out how to append this ADIF file into my HRD Logger logfile. But that's just computer stuff. Easy peasy. Thanks for the great suggestions from everyone. This list rocks.

In my opinion, that is not a big enough step above the KPA500, but some will make the case that 1500 isn't either, but at least it is the max allowed. If you're going to sell an amp above the KPA500 make it full legal limit. Leverage what you can from the KPA500, but at the same point, the KPA500 design is getting a little old. A lot has happened in high power solid state RF electronics since then. I would prefer that the amp be based on LDMOS RF Power transistors. Perhaps the MRF1K50HR5 from NXP Semiconductors should be considered. LDMOS is known for great linearity and the latest devices are pretty rugged. If you do invest in a newer design, consider some backwards leverage from the KPA1500 (if that is what you call it) to the KPA500, i.e. an updated KPA500 V2 that leverages some of the new design and perhaps makes supporting the two amps easier. I may never buy a KPA1500, but I once said that I would never want more than 100W when I bought the KXPA100, but now I own a KPA500/KAT500! 73, John AC0ZG On 3/24/2017 4:11 AM, Arie Kleingeld PA3A wrote: > Besides the usual things nearly every other hi-end linear has: > - tuner built-in as an option > - really light weight > - at least 90% efficiency > - one, max 2 antenna ports > > (these fit into the portable rig philosophy of Elecraft) > > 73 > Arie PA3A > ______________________________________________________________ > 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 jm-ec at themarvins.org From repair at willcoele.com Fri Mar 24 17:21:57 2017 From: repair at willcoele.com (wa9fvp) Date: Fri, 24 Mar 2017 14:21:57 -0700 (MST) Subject: [Elecraft] K3S USB sound issues.

While the K3 was away, I practiced using the dual watch feature on my KX2. S/N 1061 is very special to me, as it was a gift from my father only months before he passed on in 2008.

If someone wants to add KIO3B functionality to their K3 for a lot less than the upgrade to the KIO3B, this is a very clean and slick solution. With the TI-5, you have one USB cable to your computer and then the cable set plugs direct into the back of the K3. You can think of it as an external KIO3B with FSK built in. With the single USB connection, you get a sound card interface which uses the standard USB Codec just like the KIO3B, plus 4 virtual serial ports which cover CAT interfacing to the K3, FSK input to the K3 (no keying interface circuit required), CW keying and PTT via one of the virtual ports if desired and last but not least a WinKey compatible serial port for CW keying of your K3 where there is a paddle input on the TI-5. Damn, I'm almost talking myself out of selling it by describing it! ;) It's a nice little interface, but I have a K3s now and I upgraded my K3 KIO3A to the KIO3B. So the IT-5 needs a new home. I'm asking $125.00 shipped to the CONUS... or a reasonable offer based on how many responses I get. Here are a couple of pictures of what you get: http://www.nc7j.com/pa/main.php?cmd=imageview&var1=NG7M%2FRigExpert%2FTI-5%2FIMG_1892.JPG http://www.nc7j.com/pa/main.php?cmd=imageview&var1=NG7M%2FRigExpert%2FTI-5%2FIMG_1891.JPG The TI-5 has been superseded by newer versions, but the new versions have removed the WinKeyer built in interface. All the downloads for the TI-5 are on the RigExpert website. Thanks for reading. Max NG7M -- M.

I put a very small amout of WD40 on the shaft where it enters the housing bush. And then did as Don suggested repeatedly and firmly pushed the knob up at the low point. After quite a lot of pushing it began to loosen up a lot. So I feel I have a working encoder again and am going to use it for a while and hopefully I won't need to replace it. I was pretty concerned that pushing it back would damage it further but it works OK 73 and many thanks for all the suggestions Bob G3PJT On 23/03/2017 13:24, Bob G3PJT wrote: > Thanks Guy > I am going to get the encoder out from the front panel and then see > what I can do to improve things. > 73 Bob > > > Sent by Ipad > > > On 23 Mar 2017, at 11:52, Guy Olinger K2AV > wrote: > >> If you can see the bend, very slightly file the "off" side of the >> shaft and use aluminum foil to shim the other side of the shaft at >> the end.

There was a decent solar breeze earlier in the week too. Auspicious thoughts here. I am hoping for more band noise and better reception. They seem to correlate. If the band sounds like I am in the middle of cotton ball I never do well. Speaking of sound I am hearing a Saw Whet owl who has been filing away for over an hour. Now that the snow is gone more species of birds are showing up. Instead of my winter flock of Grey Jays, Steller's Jays, and Oregon Juncos the snowbirds are returning. Some of them are here for only a week; others for most of the summer. But come mid October I have only those three species again. We need to hang together in the winter. Please join us tomorrow on: 14050 kHz at 2200z Sunday (3 PM PDT Sunday) 7045 kHz at 0000z Monday (5 PM PDT Sunday) 73, Kevin.

If it is in a connector, usually removing the connector and replacing it will wipe away any oxidation interfering with proper contact. In this case it appears that the MCU is not sensing the KPA100. I would suggest that you first re-seat the KPA100 ribbon cable (both ends) and the KPA100 firmware IC. If that does not correct it, re-seat the MCU - Control Board U6. While you have the shield off the KPA100, check the diodes D16 and D17 to see if they test as good diodes. They normally show very high reverse resistance and near 430 ohms forward resistance. An alternate quick check on the health of the diodes is to measure the resistance to ground from pin 3 and pin 5 of KPA100 U5. If normal it will be about 43k. 73, Don W3FPR On 3/26/2017 9:47 AM, Gene N4FZ wrote: > This has been an intermittent problem.

This error normally occurs only at power on time. Take a look at how JT65 is set up to key the K3. I can only guess but I think that may happen if you have VOX turned on and JT65 is activating the RTS or DTR lines on the RS-232 interface, or is also activating PTT from another source. In other words, make sure JT65 is activating keying of the K3 with one source (or VOX, so the audio tones initiate transmit). If it continues, you should email K3support. 73, Don W3FPR On 3/26/2017 12:33 PM, Mike Weir wrote: > Good afternoon group, today I have been trying to operate JT65 using my K3 in DATA A mode along with WSJT-X program.

The only good termination of a cable shield is to the shielding enclosure (that is, the chassis). I know nothing about Heil mics, so can't offer advice about their adapter. I would take this issue up with Heil. But don't assume that RF is the only possibility. The mic gain and/or the compression may be turned up too high, both of which can make you sound pretty awful. And the adapter may be mis-wired -- every brand of JA radios uses a different pin-out for their mic connectors. Elecraft uses a pinout that's close to one of them (or may be the same). So connector wired for one radio is usually not right for another. Some people complain about "different standards," but this is an example of there being NO standard, and each manufacturer throwing his own darts at the board. If it is a wiring issue, all you need to fix your problem is a few hand tools and a soldering iron to open up the connectors and rewire them according to the manuals for the respective components (the mic and the radio). The Yamaha CM500 is widely used by K3 owners. I've used one since a local ham introduced our contesting club to it seven or eight years ago. Both mic and headphones sound very good and it's quite comfortable. It plugs straight into the jacks on the rear panel. It's an electret, so you'll need to turn on bias. 73, Jim K9YC 73, Jim K9YC On Sun,3/26/2017 9:31 AM, Jim Kutsch wrote: > I am a new K3S owner and very pleased.

In writing my previous response, I forgot to mention this mechanism, which can cause exactly what you are experiencing, and which has nothing to do with RFI. This is only an issue when audio is being fed to the rig via some audio accessory that runs on DC from the some power supply as the rig. http://k9yc.com/PowerSupplyBondingAndAudioDistortion.pdf 73, Jim K9YC From lists at subich.com Sun Mar 26 14:43:50 2017 From: lists at subich.com (Joe Subich, W4TV) Date: Sun, 26 Mar 2017 14:43:50 -0400 Subject: [Elecraft] RF in Microphone In-Reply-To: <007c01d2a64e$5e981210$1bc83630$@ky2d.com> References: <007c01d2a64e$5e981210$1bc83630$@ky2d.com> Message-ID: Heil's quality control *sucks*.

To provide more info as several have requested, here's the setup: The K3S is connected to a KPA500 then to a KAT500 then 25 feet of coax out to the back porch. There, the coax ends in a common mode choke, which in turn is connected by an 18 inch coax to a DX Engineering 4:1 BALUN. That feeds a Cobra UltraLite Senior via its 81 feet of 450 Ohm ladder line. The mic distortion happens with and without the KPA500 but reports say it's worse at 500 Watts. The power supply is an Astron RS35 providing 13.8V idle and 13.5V CW key down at 100 Watts. The mic gain is set to 45 and compression to 10. Those seemed to give the correct indication in the ALC meter but the distortion still occurs with 0 compression. I cannot read the ALC indicator myself due to no vision so had another local ham assist with that part of the K3S setup.

I also have the mic setting to the hi instead of the recommended low setting and also have the TXG VCE set to 2.0. Give or take, my setting should be pretty good for you, of course depending on your voice characteristics.

If you have the mic gain range set to "Low", try changing it to "High" and lowering the gain to the 10 to 15 range. Turn compression to zero while the mic gain is adjusted for 5 to 7 bars (7 on peaks) on the ALC meter. After making that setting increase the compression to whatever you desire - most like to run compression in the 10 to 15 range. See if you can borrow someone who can see the ALC meter while you talk. Set the K3 to TX TEST so you don't send RF while you make those adjustments. 73, Don W3FPR On 3/26/2017 5:38 PM, Jim Kutsch wrote: > The mic gain is set to 45 and compression to 10.

These settings should ALWAYS be set in this order: 1) Set TXEQ as desired. I recommend maximum cut of the three lowest bands, 6 dB cut of the fourth band, 3-6 dB boost of the two highest bands. Tweak the 4th band and the higher bands based on reports from good listeners, who should be listening with their IF set wide. 2) With compression OFF (set to zero), set the mic gain for ALC of 5-7 bars. 3) Set CMP so that the display shows about 10 dB of gain reduction on voice peaks. 73, Jim K9YC On Sun,3/26/2017 12:08 PM, Alan.

I had the same problem and my K3S is at Elecraft right now being repaired. The distortion above the 12 watt level is the clue. I also have the KPA500 and the KAT500 and I had a problem with my antenna that it would sometimes short out at 500 watts and the KPA500 was not set up for the KPA500. I had figured since I bought both units together they would just work. I had even read the missing instructions but they did not make sense to me so I did not do them. Now that I found out what was involved they make sense but I think that part of the instructions should be more clear or a control in the MENU should allow the settings to be compatible with the KAP500. To make this long story short if the KAT500 is not set up to be comparable with the KPA500 than if there is a high SWR it does not shut down the KPA500 and when the KPA500 does shut down all those high SWR voltages get back to the K3S and blow one of the FETs. There are two FETs so the other one tries to make up the power and of course the bad one causes distortion similar to a diode being placed across the final. I hope this information helps and for what it is worth I managed to destroy my finals twice before I found out what was wrong.

The return path to the K3s via a reflected power from the KPA500 is not acceptable and should be protected. I load my KPA500 into a matched circuit. Yes, I am sure there could be instantaneous issues, but my antennas are pretuned before I use the KPA500. Is there an opportunity for error. Yes. I operated a THP 2.5KFX at 1.5KW and saw the same antennas and never had an issue to the K3. I know the engineers are working on the issue(s).

When transmitting at 12 Watts without the KPA3 engaged, the transmit audio is completely fine. But, once I go to 13 Watts and hear the KPA3 relay engage, the audio distortion is back. I'm beginning to think I have a CONF setting incorrect or the KPA3 is bad. Even with 12 W driving the KPA500, no audio distortion. The K3S has the KPA3 module but does not have the KAT3 since I'm using the KAP500. I have CONF:KPA3 set to PA NOR. Am I missing another menu setting somewhere?

A computer is not even needed for some digital modes, and I have tried that successfully. I have mentioned in the past that I had tried the free software for digital voice on HF called 'FreeDV'. I had worked a Canadian ham a few times using it and he has been keeping in contact with me via email encouraging me to get back into it. I am starting to get up to date again, and I found accurate reviews of it on http://www.eham.net/reviews/detail/11016 by K2RWF and WA0TPN. I think you will find the reviews interesting and informative. Notice that the reviews seem to be either at, or near, 5/5 or 0/5. I think both of the reviews I mentioned answer why that is. I will keep my experience mute and let you glean aye/nay from the reviews. Whether you approve of digital voice or not, the K3/K3s is a natural for using it, and it's fun. (As always with digital modes, be kind to your finals.)

I am a new user of the K3S/KAT500 combo. Had fun using the rig during the contest over the weekend. I had it set for 100 watts and it worked very well. However, today I thought that i would place the KAT500 underneath the K3S. So after moving the KAT under the K3S I reconnected the cables and power to both units. No changes were made to any of the antennas and my swr on all antennas 80-10M is approx 1.1/1.2 - 1. I cannot seem to be able to get the output power to 100 W. I adjusted the power control for 100 W but when I transmit I can only get between 75-80 Watts output maximum. Did I happen to hit a button accidentally when moving the equipment? Any assistance would be greatly appreciated. Thanks in advance.

I have the E980232 Cable adaptor with Key Line information on the Ring. I think I could use the phone jack to send the low signal through the Ring. But when it opens up the voltage is too high?

What it *should* say is that the KX3 Keyline output will *tolerate* up to +30 volts open circuit. To convince yourself if necessary, connect nothing to the KEYLINE output jack except your DMM. It should read zero voltage. Then set the DMM to read resistance - the resistance should be high, even infinite. When the KX3 goes into transmit, the resistance should be quite low, even zero. The Keyline output is an open drain FET and produces no voltage by itself - the voltage is produced by the device connected to it. Measure the open circuit voltage of the KEYLINE *input* on the MFJ unit. In other words, do not connect anything to the T/R phone jack and measure the voltage with your DMM. If it is less than 30 volts, it can be used with the KX3. 73, Don W3FPR On 3/27/2017 4:52 PM, pentrose wrote: > I am trying to use an MFJ-1026 "Noise Canceling Signal Enhancer" with my KX3 > serial #08668. > The MFJ unit has a T/R phone jack for protecting its circuits from RF > currents when transmitting. > > Q: The voltage seems to be too high according to the Cady book.

Final Question: Is there any downside for me to use the E980232 adapter in my situation? It looks to me like the ACC2 port is mainly used for Linear Amplifiers and other things like it in signaling. And I like the KXPA 100 amplifier as it is already running. I love that it automatice turns on with the KX3 and makes other adjustments as well. The KX3 is working great.

If you have more than 2 devices connected to that KEYLINE output, there may be a voltage conflict between your external devices - the open circuit voltages for the different devices may be different and cause current to flow from one device to another. Note that this is not a KX3 problem, it is a problem between the multiple devices external to the KX3. Nothing should change in the KX3 functionality due to the KEYLINE OUT. 73, Don W3FPR On 3/27/2017 5:50 PM, pentrose wrote: > OK! Super. I will proceed on that. > > Thanks for your patience.

It may have been here on this reflector, or otherwise, on the KX3 reflector. As I recall, the KX2 ATU had slightly fewer combinations, but only because 160 and 6 meters were not included on the rig. Thus it was deemed to perform nearly identically to the K3 and KX3 ATU's, and seems to do that based on my usage. The T1 also had fewer combinations than the K3, but I think shows very similar to the KX2. My guess is that you would find the KX2 ATU to do a competent job in comparison to the T1. It is a very worthy addition to the rig. Dave W7AQK From: Dave Fugleberg How does the optional internal ATU for the KX2 compare to the Elecraft T1 ATU in terms of tuning range? In other words, if a given length of wire works well with the T1, can one expect it to work with the KX2 internal tuner? I have a T1, but not a KX2 (at least not yet). Is it a similar design?

Next is the posting with the tabulation, attached below a response from Wayne with important KXAT2 design remarks, compared to the T1: http://mailman.qth.net/pipermail/elecraft/2016-May/232436.html In summary, both the KXAT2 and the T1 ATUs use 7 inductors and 7 capacitors in an L-network low-pass filter, where the capacitor array may be switched to either side of the inductor array. That gives 32764 unique configurations for both ATUs. However, the T1 must use those 32764 between 160m and 6m, while the KXAT2 uses its 32764 between 80m and 10m only. Thus, within the KXAT2's reduced frequency range, it performs more precisely to generate a match, compared to the T1 between 80m and 10m. Bottom line: The KXAT2 is superior to the T1 over the KX2's operating frequency range.

Don's report stated that the radio met or exceeded factory specs (documentation provided to new owner). The serial number is 31XX, so it is a Rev "B" version which meets current production. I am the second owner and I installed most options, including the 100-watt module. The radio includes: KNB2 - Noise Blanker board KSB2 - SSB board KIOS2 - Serial Interface (with radio-to-computer cable) KAF2 - Audio Filter and Realtime Clock Kenwood MC-43S hand mic All construction and operators manuals. I love this radio, but I have to let go of some things. After all these years, the performance of the K2 is still top shelf; if I can hear it / work it on my K3, I can do it on my K2. My firm price for the all of the above is $650 including Priority Mail shipping to any US ZIP code. If you are anywhere near Santa Barbara, CA, I would be happy to demo the radio. I do have pictures and, yes, I take PayPal. 73 de K6SBA David Inger From n7xy at n7xy.net Mon Mar 27 22:46:48 2017 From: n7xy at n7xy.net (Bob Nielsen) Date: Mon, 27 Mar 2017 19:46:48 -0700 Subject: [Elecraft] K3/K3s; Digital modes, specifically DV In-Reply-To: <583610483.4358559.1490666099877@mail.yahoo.com> References: <9962106.4902230.1490650133456@mail.yahoo.com> <969563263.4899181.1490663721633@mail.yahoo.com> <6eb01933-6fdd-6ab6-8e4c-e39f3e0c50fc@n7xy.net> <583610483.4358559.1490666099877@mail.yahoo.com> Message-ID: <1f593492-a4f2-b788-63b5-73e54f44ca53@n7xy.net> The more I look at the mcHF, the more impressed I become.

Next is the posting with the tabulation, attached below a response from Wayne with important KXAT2 design remarks, compared to the T1: ? http://mailman.qth.net/pipermail/elecraft/2016-May/232436.html In summary, both the KXAT2 and the T1 ATUs use 7 inductors and 7 capacitors in an L-network low-pass filter, where the capacitor array may be switched to either side of the inductor array.? That gives 32764 unique configurations for both ATUs.? However, the T1 must use those 32764 between 160m and 6m, while the KXAT2 uses its 32764 between 80m and 10m only.? Thus, within the KXAT2's reduced frequency range, it performs more precisely to generate a match, compared to the T1 between 80m and 10m. Bottom line:? The KXAT2 is superior to the T1 over the KX2's operating frequency range.

If you're not already following along on David's blog it's worth a read (http://www.rowetel.com/) his writing style is easy going and he explains things well. His current work on Codec2 700C surpassing MELP 600 in performance along with some new modem ideas will push the limits of what's possible with Digital voice on HF. It will not be long and the performance of FreeDV will be equal too if not surpass SSB on a standard HF channel. Yes this can be done already, however you do end up sounding like donald duck and a bit robotic for my liking on current technology. The work on Codec2 will change this. While the FreeDV code base (Modem + Codec2) is open source the integration work is not insignificant. The current FreeDV codebase in the SM1000 runs on a STM32V405xxx 32-bit ARM core clocked at 168MHz with a real FPU and no RTOS it runs bare metal. That is some serious beans in terms of DSP processing !!! The effort involved in bringing this into any product should not be underestimated, there is still some very serious work to do which results in $$$ spent. While FreeDV is under active development interfacing a linux based laptop to the K3 and using this to keep up with the Jones's is perhaps the best course of action. Those with the K3s are already ahead of those with a stock K3 since they already have the internal USB sound card. However making cables for laptops and PTT cct's isn't hard either. Once the performance of FreeDV surpasses that of standard SSB then would it be time for internal integration work to begin. I'm fingers crossed that the processors and DSP in the next iteration of the K-line will have enough processing beans to "answer the meaning of life the universe and everything" in real time. As David tells me on the local repeater most mornings "MIPS are cheap". That is about the time frame I'd expect both of these technologies to collide. YMMV. 73 Matthew VK5ZM On 28 March 2017 at 04:40, Richard Fjeld wrote: > Greetings to all, > > The K3/K3s is an excellent radio for digital modes due to the ease of > interfacing with a computer if desired.

To avoid sub receiver signal loss, use the sub?s AUX input." With SUB active, hold down RX ANT to toggle the Sub RX antenna between MAIN and AUX. I understand that the Sub receiver's audio is fed to the other stereo channel but is that true for the Line Out port? Can the Sub-Receiver feed audio via the USB CODAC? Yes.

I've played with FreeDV too and it has some great possibilities. The only issue run into is there's only a small group of people using it so it's often hard to find someone else on to talk to. I find It works best on the higher (and quieter) frequencies such as 20m and up. So you have to catch an opening and find people that are the right distance away and monitoring in FreeDV mode. I really hope we can get more people interested in FreeDV and if it could be added into the K and KX series firmware update that would help it grow.

Why do you assume people are lucky enough to have antennas with no more than a 3:1 SWR across the ham bands? Yes, higher SWR's require beefed up components but welcome to the real world. 73 de Brian/K3KO On 3/28/2017 23:00 PM, Paul Van Dyke wrote: > Ralph Parker said my list..... > > 1500w output, 160 - 6m. > 2 inputs. > 4 outputs (Manual switching is OK). > Built-in antenna tuner (good for 3:1 SWR). > Reasonably quiet fans. > Separate p/s, or remote control head (space considerations. :-) > > Paul.

Mode selection on KX3 is AFSK A and cocoaModem setup is matched to the KX3 setting. RTTY signal received by KX3 appears not around 2125Hz but around 900Hz. So, I set cocoaModem?s mark frequency to 915Hz. With that setting, decoded text appears on the screen. KX3 VFO is properly tuned to the signal, of course. When FSK D on KX3, all is same. RTTY signal appears around 900Hz as well. I found this had been discussed several years ago in the ML, but no change in KX3 specification since then. I would like to know if this mark frequency is OK in QSO with other RTTY station. 73 de JH3SIF, Keith From donwilh at embarqmail.com Tue Mar 28 20:37:15 2017 From: donwilh at embarqmail.com (Don Wilhelm) Date: Tue, 28 Mar 2017 20:37:15 -0400 Subject: [Elecraft] KX3 - AFSK RTTY In-Reply-To: References: Message-ID: <8cfc8f78-6485-4eb1-6646-e2cd45493a28@embarqmail.com> Keith, The other station will not know what mark frequency you are using. The only thing the other station hears is your mark and space frequencies (and the resultant shift), so if you are using the proper RTTY shift, he should copy you with no difficulty. Yes, there are some folks who are reluctant to use low tones with RTTY because the 2nd harmonic of that tone falls within the SSB bandwidth. I would suggest you ignore those comments - the KX3 works fine with the lower tones. I am not certain what you meant about FSK D - you should be using AFSK A, so FSK D is not relevant. I do not do Mac and I do not do CocoModem, so this may be some mixture of settings between the KX3 and CocoModem that do not make sense to me. Does CocoModem support soundcard RTTY? That is what you should be using, no matter what CocoModem calls it. FSK D mode with the KX3 is used to send RTTY from CW paddles (not computer input - the KX3 must see the dots and dashes directly from the paddles). An alternative to the paddles for FSK D input is a software application that can send "KY" commands with ASCII text. Few applications other than KX3 Utility have that capability. 73, Don W3FPR On 3/28/2017 8:04 PM, Keith Onishi wrote: > I have been trying to set up for RTTY operation with KX3 + iMic + cocoaModem on Macbook Pro, but not successful. > Mode selection on KX3 is AFSK A and cocoaModem setup is matched to the KX3 setting. > RTTY signal received by KX3 appears not around 2125Hz but around 900Hz.

VSWR tuning range for both should be 10:1 to 1:1 with no tuning gaps or compromises (I really don't mind paying the extra to achieve this). I'd like the KPA1500 to have full on/off switching on the front panel, and USB rather than D-sub connectors on the rear panel. At least TWO selectable radio source inputs and THREE selectable antenna output ports. While we're on wish lists, I'd LOVE to see Elecraft produce a VHF/UHF/Microwave radio that looks and operates almost like the K3s with 144MHz, 220MHz, 440MHz, 1296MHz, 2400MHz, etc. (maybe optional modules on the upper bands). Separate antenna ports per band, 100W TX (maybe a bit less on the upper bands), all-mode, alpha-numeric labels for memories (a la Yaesu FTM-400XDR), click-mode main tuning dial selectable (like IC-7000), and a super-fast scan feature.

These cost far less per unit price than the components required to beef up an internal tuner to handle impedance's of 500-800 ohms or more (or the conjugate) with a solid state amp. A simple 3:1 impedance transformation is not expensive in terms of components and allows you to flatten out the band edges of a dipole or beam. Out side of this your amplifier is asking you to pay attention. For those wanting to use antenna with high impedance (or very low impedance) feed point there are tuners already that will suit your purpose. Thinking about that it would be nice if the KAT1500 could have some form of tuner interface (like the Icom and Kenwoods) where an external tuner can be activated, RF applied and held until the tuner releases the tune line. In the real world as you put it capacitors look like door knobs and inductors are large enough to stand in and everything is silver plated. There's that pesky issue with the voltage being the square of the current for a fixed impedance, it does take long for things to get nasty as you increase the current by 1 or 2 amps at a time. 73 Matthew VK5ZM On 29 March 2017 at 10:00, brian wrote: > KAT500 handles a much wider SWR range (like to about 10:1). > > Why do you assume people are lucky enough to have antennas with no more > than a 3:1 SWR across the ham bands? > > Yes, higher SWR's require beefed up components but welcome to the real > world. > > 73 de Brian/K3KO > > > On 3/28/2017 23:00 PM, Paul Van Dyke wrote: > >> Ralph Parker said my list..... >> >> 1500w output, 160 - 6m. >> 2 inputs. >> 4 outputs (Manual switching is OK). >> Built-in antenna tuner (good for 3:1 SWR). >> Reasonably quiet fans. >> Separate p/s, or remote control head (space considerations. :-) >> >> Paul.

Why do you assume people are lucky enough to have antennas with no more than a 3:1 SWR across the ham bands? Yes, higher SWR's require beefed up components but welcome to the real world. 73 de Brian/K3KO From dpbunte at gmail.com Wed Mar 29 08:11:01 2017 From: dpbunte at gmail.com (David Bunte) Date: Wed, 29 Mar 2017 08:11:01 -0400 Subject: [Elecraft] Amplifier thoughts In-Reply-To: <8d6a6601e07a9e031250505577d3eabe.squirrel@www11.qth.com> References: <8d6a6601e07a9e031250505577d3eabe.squirrel@www11.qth.com> Message-ID: John - I used to live in the world you do... but I now live in a neighborhood where I can't put up a tower, or even a multiband dipole. My 30' Flag Pole is OK, and, in fact, my neighbors think it is quite nice looking, but in order to use it on more than the one band where its unmatched SWR is less than 3:1, I must use a tuner. I don't expect to be in the market for an amp that is more capable than my KPA500, but my guess is that an optional, internal tuner capable of handling 1500 watts into a 3:1 or lower SWR, would suite quite a few potential users quite well. That way, someone like you, who does not need a tuner at all could opt to not order that option. If Elecraft chooses to market an external tuner capable of handling 1500 watts into a 10:1 SWR, then I hope it is one that could be placed out at the antenna, and controlled remotely. For some folks, putting such a tuner in the shack, but out of sight would be equally appealing.

It included within its huge & heavy black box the switching power supply and the 3:1 antenna auto-tuner. I sold that amplifier because my eyes sparkled in delight with a much, much smaller desktop KPA500 from Elecraft. If this new 1.5 KW linear (if that is the power) becomes a reality, having it come in three separate boxes may make some sense. Alternatively, like the Icom PW1, have a control head that sits on the shack desktop and the main unit containing everything else would be on the floor in a dark corner where it belongs (and, where I had my PW1). But, being honest, I will not be in the market for a larger amp as 100 watts seems quite a bit for my operations which is 99 percent CW and QRP ops or even 10-watt QRP ops with my KX2 is a lot of fun. 73, phil, K7PEH From RLVZ at aol.com Wed Mar 29 13:12:29 2017 From: RLVZ at aol.com (RLVZ at aol.com) Date: Wed, 29 Mar 2017 13:12:29 -0400 Subject: [Elecraft] K3- padded carrying case Message-ID: Hi Guys, Please advise what's currently available in padded equipment or carrying cases or the K3?

Sure, it could be optional but see points 2 and 3. 2) An internal coupler at 1.5 KW as anything beyond a trivial ?line flattener? will be large. If the matching range is extended to the 10 : 1 SWR range then the components will be *quite* large. Feeding 1.5 KW into a 5 ohm load with an L-Network will require an inductor about the size of a K3S if any sort of Q is expected. 3) There exist RF transistors that are built to withstand high power operation with really high SWR values. For example: http://www.nxp.com/products/rf/rf-power-transistors/rf-broadcast-and-ism/1-600-mhz-broadcast-and-ism/1500-w-cw-over-1.8-500-mhz-50-v-wideband-rf-power-ldmos-transistor:MRF1K50H Surely with such a device (or, better yet, a pair), a 3 : 1 SWR can be accommodated with no coupler at all. Thus, no line flattener needed. If someone is trying to feed a 43 foot vertical on all bands at 1.5 KW then the coupler really should be at the antenna site, not in the shack. That antenna presents a load of about 5 ohms -J500 and the coupler will have to be large at 1.5 KW. (This is RF, not DC. In a high pass L-Net think 18 amps and 9000 peak volts with a staggering 600 watts of losses generating heat in that coil.) As to the amp itself my wish list would include: 1) 1.5 KW ICAS. (I would accept 1.3 KW but, hey, it?s a wish list.) Must be contest capable, including those crazy RTTY guys. ;-) 2) Separate light weight power supply. 3) QSK at reasonable speeds. At least 40 WPM. 4) Multiple antenna outputs, remembered per band; overridable. 5) FULLY integrated with the K3S. Given proper antenna loads the K3S + KPA1500 becomes a 1.5 KW transceiver. 6) A remote console setup would be cool. That way the amp would be just a power block that could be set aside, out of the way. Or, even operated at a remote site from the console. TCP/IP connectivity for the console to power block. 73, Doug, W7KF http://www.w7kf.com From pa3a at xs4all.nl Wed Mar 29 13:36:20 2017 From: pa3a at xs4all.nl (Arie Kleingeld PA3A) Date: Wed, 29 Mar 2017 19:36:20 +0200 Subject: [Elecraft] Amplifier thoughts In-Reply-To: <656014C5-9555-4EBE-8307-FEEC4DAA4D74@mac.com> References: <8d6a6601e07a9e031250505577d3eabe.squirrel@www11.qth.com> <656014C5-9555-4EBE-8307-FEEC4DAA4D74@mac.com> Message-ID: <0945efd6-6e1d-456d-cee4-f392e1340c38@xs4all.nl> Who needs three boxes if it has a switching power supply and the amp itself has >90% efficiency?

In practice, it is usually the voltage breakdown that kills coax. Of course high SWR also means high losses between the amp and the antenna. The power ratings published by coax cable suppliers are based on a low SWR -- typically less than 1.5:1. The bottom line is that going QRO means a more careful design and installation of the entire antenna system. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of brian Sent: Tuesday, March 28, 2017 4:31 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Amplifier thoughts KAT500 handles a much wider SWR range (like to about 10:1).

My point is that the sort of SWR we might accept at lower powers quickly becomes impractical at higher powers because of the constraints imposed by the transmission line. The sort of coaxial line most Hams use, even the super low-loss big stuff, simply cannot handle the voltages produced by a high SWR. The place to do the matching is at the antenna end of the transmission line. So how about a weather proofed remote QRO ATU that goes at the antenna end of the transmission line? As others pointed out such an ATU won't be small due to the potentially huge voltages and currents involved, it won't be lightweight and it certainly won't be cheap. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Jim Brown Sent: Wednesday, March 29, 2017 12:11 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] Amplifier thoughts On Wed,3/29/2017 11:47 AM, Ron D'Eau Claire wrote: > An SWR approaching 10:1 means high RF voltages on a coaxial line at > the voltage loops Remember that the SWR on a transmission line, and thus the loss in the line, is determined ENTIRELY by the match between the antenna and the line, NOT between the line and the transmitter.

In fact, I tend to disable the KAT500 and turn on the KAT100 in the K3. Therefore: A KAT1500 should either have sound absorbent materials built in, or else be mounted away from the operating position.

Most of the time I use it on my home QTH desk, right next to the K3/100 and P3. Hardware-wise, I am quite happy with it. One thing that is a bit annoying is not being able to backup / restore the KX3 internal tuner settings. Why? Well, after going through each band and all of the segments on each of them, training the KX3 tuner, it really is not cool to take the rig out on a micro or mini DXpedition and loose all the home antenna settings when the rig gets trained for use with a portable antenna. Coming home then means having to go through the training process all over again. Being able to back up the L/C settings before heading out the door and then restoring them when you come back home would be great. 73, Jim / W6JHB > On Wednesday, Mar 29, 2017, at Wednesday, 6:35 PM, Wayne Burdick wrote: > > Hi all, > > The weather's been great in the Bay Area lately.

I have had a project which has sit on the back burner for a long time. Here are the requirement notes I have: Make switching between Data/Voice/CW easy - handle VOX, Mic bias & levels. Connect to computer/phones/mic to the radio without switching plugs. Contain "sound card"? + hub + RS232 to USB --> one cable computer connection ala K3S Run headphones/speaker + digital at the same time Amp for stereo speakers All of these seem to be relatively easy, at least I thought I could do them. However life has left them as just a desired list. If you do them before me, I'm likely to buy your solution. 73 Bill AE6JV ----------------------------------------------------------------------- Bill Frantz | Security is like Government | Periwinkle (408)356-8506 | services.

What future accessories, antennas, etc. would you like to see for the KX-line?? I'd like a 2M and 70CM transverter for working the linear satellites. Ideally it would be capable of full-duplex operation with reverse VFO tracking, but I'd settle for being able to use it half-duplex. A lot of folks use one or two FT-817NDs as the foundation for their portable satellite station, and it would be nice to be able to do that with the KX3 or KX2. While an internal unit would be more convenient, an external unit would offer the possibility of working with both the KX3 and KX2, and a larger connector (BNC, N, or SO239) for use with typical beam antennas. ? I might buy an iambic or single-lever paddle that connects to the KX3 with the paddles pointing to the left. To use the KXPD3 without my wrist cramping up, I'd have to turn the KX3 90 degrees to the left.? More programmable function keys for storing macros or menu items would be useful on the KX3. Maybe hold PF2 then press any other button to access the programmable function stored there. The same approach could be taken with the KX2's single PF button.? More DVR memories would be useful, even if they draw from the same memory storage, e.g., if the total stored time for all messages was limited to 30 seconds or less. Even just one more memory would be incredibly helpful for Field Day and other contests: ?call, CQ, and exchange.? 73, Ryan AI6DO From glen.torr at gmail.com Thu Mar 30 00:32:51 2017 From: glen.torr at gmail.com (Glen Torr) Date: Thu, 30 Mar 2017 15:32:51 +1100 Subject: [Elecraft] Future KX3/KX2 accessories?

Here's a few non-trivial brainstorms: 1) A bluetooth interface that allows rig control and audio I/O on a nearby (smart-) phone. While the front-panel UIs of the KX2 &KX3 makes really clever use of limited knob and switch space, being able to build richer interfaces into the phone would be awesome. The possibilities become really crazy then: Logging, some kind of mini waterfall display, sound recording and playback, comparatively unlimited freq. memories with extended meta-data, calendar interaction, storing QSO logs for later acknowledgment in email, slow-scan TV support, etc. and too many other et ceteras to count. 2) An automotive (12V) charger for the on-board KX2 battery. 3) A really tiny, ultralight 9:1 UNUN--perhaps AA battery size. This would be for matching a long wire antenna that doesn't start right at the radio (instead of using the BNC-binding-posts adapter) in situations when you want the radiating wire some distance away, like outside your car, tent, or a metal-roofed cabin. Imagine trying to make contacts from inside this kind of building in the dead of winter after carrying your gear in on skis or snowshoes: [ http://clairtappaanlodge.com/bradley-hut ] 4) An "Otter Box" style or neoprene case for both the KX2 & KX3 that would protect them from slightly rougher handling. And I second the idea for a way to back up all of your memories, settings and tunings. --Steve, KC6ZKT From irmalinas73 at gmail.com Thu Mar 30 02:37:13 2017 From: irmalinas73 at gmail.com (Irma & Linas(LY2H)) Date: Thu, 30 Mar 2017 06:37:13 +0000 Subject: [Elecraft] Future KX3/KX2 accessories?

I support very mich the idea or the need , really, of an in-built bluetooth rig control and audio I/o connection interface to a portable devices. For if you have an iPad or an iPhone you can not connect them to nothing and nothing can be connected to them by wires :). Yes, I have a Pigtail thing but it's too complicated to use in the field and it makes one more box hanging around and the software available is rudimentary one. With mobile devices taking over laptop and desktop computers almost massively in the daily life use, not having a chance to use it for the KX line ham radio applications is just a great mistake! 2. I use my KX2 a lot in the mobile operating with the magmount antenna. The rig just sits on the front seat near me and it is no problem to operate the CW paddle. Just one thing - it would be nice a second PF button because now I have to choose what I want to use it for- the VOX on/off or the Xit on/off for example. While on road and driving it is tiresome and dangerous to mingle with the menu settings. Actually the VOX setting should stay always on if you switch it on. at the moment you have to switch it on on every power-up. 73!

You can get one from Elecraft. Be certain that you do use the K2 to PC cable. If you get a USB to serial adapter that has a long tail, you may want to shorten the K2 to PC cable, but it must be present to avoid damaging the K2 or the serial port. Do not plug a serial port (or adapter) into the KIO2 directly. 73, Don W3FPR On 3/30/2017 9:43 AM, Paul Huff wrote: > I am adding a KIO2 to my Elecraft K2 and will of course build the required interface cable per the Elecraft instructions.

I realize the kx3 could be equipped to receive 2 meters now but that's a lot of kit compared to an 817 just for 2 meter receive.... Maybe same footprint as a kx2 or 3 and mount right on the back for good field integration..with space reserved for the transmitting converters when they become available...if we have to wait. :) And the Yaesus are getting a bit long in the tooth....might be a great time to crack the U/V market. In the meantime how about a small (like Kenwood ht size) speaker mic with volume control for the kx2/3? With a good button (or 2) for cw keying while walking? 73 Scott Sent from my iPad > On Mar 30, 2017, at 6:55 AM, Paul Stoetzer wrote: > > A KX2 or KX3 sized full-duplex 2m/70cm radio would be amazing and fill a > big hole in current product availability. > > Lots of satellite ops currently use an "FT-1634" or "FT-1674" (2 FT-817s > or > 1 FT-817 & 1 FT-857) for this purpose. > > 73, > > Paul, N8HM From ken at arkayengravers.com Thu Mar 30 11:27:08 2017 From: ken at arkayengravers.com (Ken Kaplan) Date: Thu, 30 Mar 2017 11:27:08 -0400 Subject: [Elecraft] [KX3] Future KX3/KX2 accessories?

Message-ID: <1b62e7b4ad584e77bae4f150490ad40f@EX2013-MB.cotrnet.cotr.bc.ca> Wayne, As we head into the noisy bottom of the sunspot cycle, I would like a portable radio that I can knock-around on camping trips. - Portable; not ultra light - Waterproof, shock resistant - Should be effective for checking into ssb nets on 75m - I think the sweet spot would be 40W - Self-contained, large capacity battery ... LiFe? You could leverage the KX2 with a small 6dB amplifier/tuner and robust battery power supply. All fitting inside a waterproof Pelican-style case. The big engineering challenge here is packing enough power storage into the design. Naturally, we'd want in-situ charging from vehicle, solar, or mains. Without removing the battery, please ;-) You'd capture the pole position for wilderness adventure, RV, motorcycle, boating, emcomm, etc. There would even be some non-CW SOTA types willing to carry that radio up a mountain (they're already using Yaesu FT-857 or small, dirty amplifiers.) Nathon Hall VE7ETS -- Hi all, The weather's been great in the Bay Area lately. That always makes us want to escape the lab for microDXpeditions to local parks, trails, beaches, and summits. This is what the KX-line is all about.

The main board is also a multi-layer type, so we could sandwich most of the noisy digital signals between signal ground planes, shielding them pretty effectively. This solved the problem of digital noise getting into the K3S rx. In the KX radios, digital noise would be in close proximity RF boards, so that opportunity is not available to us. 73, matt W6NIA On 3/30/2017 7:58 AM, Walter Underwood wrote: > That was my single complaint with the KX3, even before I bought mine.

Others [like Keyspan] appear to use the Prolific [most of the time]. Three older Prolific models are not supported in Windows 10 and will give "Error 10" when plugged in. Prolific has also had problems with counterfeit chipsets from "you know where." Many of these do not implement the entire standard and people have had problems with them and drivers, beyond the Win 10 issue. You can purchase a guaranteed FTDI adapter cable from Elecraft, I just did and it works fine. You can also find them on Amazon, however I decided against those since their provenance is not really clear. BEWARE: The DE-9 on the back of the K2 is *NOT* a regular RS-232 serial port. Three of the pins [RXD, TXD, GND] conform to RS-232 standards, the remainder are internal K2 signals for the 100W ATU. Elecraft sells an adapter cable that passes just the three signals, or you can easily make your own. Plugging the USB-Serial adapter directly into the K2 will likely damage the radio. 73, Fred ("Skip") K6DGW Sparks NV USA Washoe County DM09dn On 3/30/2017 6:43 AM, Paul Huff wrote: > I am adding a KIO2 to my Elecraft K2 and will of course build the required interface cable per the Elecraft instructions.

I support very mich the idea or the need , really, of an in-built bluetooth rig control and audio I/o connection interface to a portable devices. For if you have an iPad or an iPhone you can not connect them to nothing and nothing can be connected to them by wires :). Yes, I have a Pigtail thing but it's too complicated to use in the field and it makes one more box hanging around and the software available is rudimentary one. With mobile devices taking over laptop and desktop computers almost massively in the daily life use, not having a chance to use it for the KX line ham radio applications is just a great mistake! 2. I use my KX2 a lot in the mobile operating with the magmount antenna. The rig just sits on the front seat near me and it is no problem to operate the CW paddle. Just one thing - it would be nice a second PF button because now I have to choose what I want to use it for- the VOX on/off or the Xit on/off for example. While on road and driving it is tiresome and dangerous to mingle with the menu settings. Actually the VOX setting should stay always on if you switch it on. at the moment you have to switch it on on every power-up. 73!

For example, I know why I didn't buy a set of paddles. I'd never use them. I'm not sure why I bought the microphone, I've used it very little. Lots of folks use those, so I'm glad they are options. I like the Bluetooth idea too, for much the same reasons. If there are cool ways to use the BT that are outside the scope of the scope, then I'm in favor of that. On the knob question, in many of the digital modes, you park the VFO in one spot and tune with your mouse and the waterfall. Can't get excited about a "better" knob, but I'm not opposed to it. 73 - Lynn On 3/30/2017 11:20 AM, Steve Sergeant wrote: > I hope we can be more creative than that! > A sound-card type interface within the unit opens up whole new doors of > possibilities.

I have an Alpha 9500 and Palstar HF-Auto that works just fine but I enjoy the way my KPA500/KAT500 along with the K3S works seamlessly with one another. Surely a solid state amp and tuner could replace my present setup with less real estate. I took the time to train my KAT500 with my antennas and really works nice. With my other setup the Palstar has to do its thing with RF applied and the alpha has to do its thing. The Alpha takes three minutes to warm up and the KPA500 instantaneous and has 6 meters as well where the Alpha does not. I'm not degrading the Alpha and Palstar at all because they do work and quite well. Ed..

Message-ID: There are various circumstances and 1.76dB may or may not be important. Much depends on your interests and goals. I am curious how you combined two KPA500's. The commercial combiners that I have seen are extremely expensive and are not set up for the KPA500 automatic band switching. Perhaps an Elecraft KPA combiner would would be a good option? John KK9A from: Richard Thorne rthorne at rthorne.net Thu Mar 30 12:31:48 EDT 2017 I have a pair of KPA-500's for an SO2R setup. Seamless. I've been running the numbers on the advantage of going to 1000 or 1500 watts. 500 watts to 1000 watts - 3.01 db gain 500 watts to 1500 watts - 4.77 db gain Will the increase from 1000 to 1500 watts or a 1.76 db increase in gain, make a difference? I'm sure it would in some circumstances, but how often? I'm just starting on my quest to increase my dxcc totals on 80 and 160, so maybe that 1.76 db would be the difference between a having a qso or not having a qso.

The USB on the K3s provides all the RS232 functions. I mainly use it for digital sw run on the computer, but I also have an utility that controls the K3 VFO and keys PTT. I can use it for panadapter use, as well. I use the FDTI USB/RS232 cable from Elecraft. Comment on the original topic, It seems a cable interface/switch box is a perfect after-market item for someone to make for the KX2/KX3. A dual-band VHF/UHF transverter with external battery box to clamp-on behind either radio is a nice concept, but the radios are not capable of duplex operation, so this still falls short of what the satellite community desires. The satellite population is just too small for a decent market for a new all-mode duplex dual-band radio. Also SDR's are making big inroads into this market so look for this to come out of that industry. In fact one can do that with a KX3-2M adding a UHF SDR. Long-range development of ham-sats will be moving to mw and utilize digital modes, only (meaning DV as included). FEC digital is the direction of communications tech. Its already in your smart phone. 73, Ed - KL7UW ------------------ Date: Thu, 30 Mar 2017 09:53:57 -0700 From: Phil Hystad To: "Lynn W.

Near the top of the list (other than bug fixes) will be a new menu entry that lets you choose one of two sets of ATU tuning data.

It now sits about 1/16th of an inch down from the top face of the knob, and it has greatly enhanced my ability to manually scan through the frequencies. I just put the tip of my right index finger at the side of the knob so that I'm touching both the O-ring and the upper edge of the knob, and that allows me to scoot merrily through the frequencies. The O-ring is black so it blends well with the rig and is barely noticable. ?

First of all, the K2 MCU RX and TX signals need to be TTL (0 to 5V) instead of RS-232 and the polarity must be inverted - so you will need some more logic circuits to make it work. 2nd, the KIO2 provides internal K2 signals needed for Elecraft accessories like the KAT100, KRC2, XVseries Transverters. If you ever want to add any of those accessories, you will be back "where you started". 3rd, if you ever add the KPA100, you will have to give up all your work. Although that device will mount on the KPA100 board, the levels and polarity are not right AND it contains ALL the RS-232 signal lines, not just TXD and RXD and Signal Ground. You would have to make extensive modifications to the KPA100 board to make it work - and you still do not have the internal K2 signal lines to support the external Elecraft accessory boxes. Simple "solutions" are often complex. It is easier to use an external USB to serial adapter IMHO. 73, Don W3FPR On 3/30/2017 3:43 PM, Harry Yingst wrote: > > Instead of a KIO2 I am installing a DB9-USB-D5-F > > USB straight to the K2 > > > ------------------------------------------------------------------------ > > From brian at kf6c.com Thu Mar 30 16:41:00 2017 From: brian at kf6c.com (Brian D.

I have recently been working on understanding the lack of sensitivity in a 900 MHz ISM device. This device is controlled by an FTDI245RQ USB interface. The clock for this device can be an internal 12 MHz oscillator or a 24 MHz external oscillator. The internal oscillator has very poor phase noise and its 76th harmonic, present on the USB data lines, is strong enough to de-sense a 900 MHz RX over a 7 MHz wide band. The DE0-Nano FPGA development board which has a similar USB controller but with an external 24 MHz clock also radiates significant energy on the 38th harmonic of its clock.

The main board is also a multi-layer type, so we could sandwich most of the noisy digital signals between signal ground planes, shielding them pretty effectively. This solved the problem of digital noise getting into the K3S rx.

In-Reply-To: References: , Message-ID: I use W6PQLs combiner/splitter pair for the RF paths. I use an Arduino to handle switching the band data from the two K3s, along with the keyline. I switch the pair between the radios using the Tx Focus line from a u2R as control, which drives 4 TopTen A/B switches to switch the combo between the radios. I also modified the KPAs to increase their gain a bit. NX1P has a good writeup about removing the pad in the amp and modifying the power sense circuit. The KPAs will work without modification, but I ran out of drive on the higher bands. Now getting 1000+ out on all bands is easy. So far no problems. I use my logging program and the MicroHam router program to insert some delay between activation and RF application. So far it's been pretty bullet proof.

Way back the early books from the 1930's that I read and the OT commercial operators from that era I knew said that under typical conditions found on the air, 6 dB was about the minimum change to hear a real difference in the signal while exchanging messages or other extended information. Those stations would not try a direct contact if the signals were "in the mud" opting instead for trying again at different time or getting a relay. In commercial operations we did not use the Ham RST system, but rather QSA 1 through 5. 1 was a barely detected signal in the mud. 5 was a loud signal with perfect copy. I confess to doing about the same with Ham signals, choosing between at most five levels by ear for my report without reference to an S-meter. Personally, I've never gotten very excited about anything less than a 10 dB improvement, but the only DX I work are those calling me - usually for a rag chew - and I don't contest. And, for me, Ken's observation is quite right. If I get the bug to drop my Inverted L, rub some RF grease on the wire, neaten things up in general and restring it, I do think I am getting out better and stations seem to come back more quickly.

The NDB is an aviation non-directional beacon that used to be common at airports and now are found surplus (if you look). I got mine for $40, fully operational, with built-in ac PS. It normally runs on a xtal LO which I gutted and drive with a simple coupling capacitor at 0.1mw (K3 run in TEST mode with output taken from transverter Tx out jack). I retained the tunable coil bandpass filter which drives a 2N2222 followed by two more transistor stages. But by removing audio transformers and low pass filters many 100w stereo amps will work at this frequency. Biggest challenge on this band is the antennas. Half wave at 472-KHz is over a thousand feet. The std inverted-L so popular for 160m is what I am using. Mine is 43-foot high by 122-foot long and multi-wire to lower Q. The base loading coil is 11 by 10 inch with 1/4-inch winding separation using No. 12 house wire (without insulation). Low noise receiving antennas are needed. Band performs best in winter when there is little lightening static. My 600m webpage is down but I show a lot of antenna info there. Guess I need to restore it. I achieve 4.15w ERP with 100w drive.

Well, I might have done it. I like a little heavier knob on my radios. Ever since I had an HRO radio. ??? I took the KX2 knob and put 4 nuts in each of the four bins in the back of the knob. I took some modeling clay and forced it in to hold the nuts and to give more weight. I think that is just about perfect for weight and inertia. Comments? ??

In-Reply-To: References: Message-ID: <0fc5309e-be9e-ca4e-46de-87399d955aff@embarqmail.com> With 2m/70cm FM handhelds on the market selling for $35 to $100, I would think it unwise for Elecraft to attempt to delve into that market, even if it included multi-mode. Yes, an All-Mode 2m/70cm transceiver would be attractive (and they exist), but I suspect the current price point for those transceivers would not be attractive to Elecraft. In addition, Elecraft is dedicated to quality products, while the current competition does not seem to be similarly dedicated - "sell them as cheaply as you can" and hope the sales volume will make up for the deficiencies seems to be the current focus. It seems to me that most activity on 2M/70cm is FM, and those doing other modes are a select (small) group. So if you are among those who desire SSB, CW, and modes other than FM on 2m/70CM, then let your voices be heard, but until there is a significant amount of operating those bands in your favorite style, your choices of ready built equipment will be small. As a parallel, I recall when I was starting out in ham radio (1950s) that there was little commercial gear for VHF (50MHz and above). Those who delved into VHF operation were experimenters and pioneers who built their own transmitters and receivers. At that time the Technician Class license was one for experimenters, and not an entry license. The Heathkit 6er and 2er changed some of that and opened the VHF spectrum to many more hams - that was AM rather than FM. 73, Don W3FPR 73, Don W3FPR On 3/30/2017 6:06 PM, Bill Frantz wrote: > The 2M option for the KX3 supports transmit at about 3W output.

Way back the early books from the 1930's that I read and the OT commercial operators from that era I knew said that under typical conditions found on the air, 6 dB was about the minimum change to hear a real difference in the signal while exchanging messages or other extended information. Those stations would not try a direct contact if the signals were "in the mud" opting instead for trying again at different time or getting a relay. In commercial operations we did not use the Ham RST system, but rather QSA 1 through 5. 1 was a barely detected signal in the mud. 5 was a loud signal with perfect copy. I confess to doing about the same with Ham signals, choosing between at most five levels by ear for my report without reference to an S-meter. Personally, I've never gotten very excited about anything less than a 10 dB improvement, but the only DX I work are those calling me - usually for a rag chew - and I don't contest. And, for me, Ken's observation is quite right. If I get the bug to drop my Inverted L, rub some RF grease on the wire, neaten things up in general and restring it, I do think I am getting out better and stations seem to come back more quickly.

Light enough to be used as an HT. Goat-optional on longer hikes. Even 1 ounce of additional weight can increase fatigue when holding a device (try, for example, carrying around an iPhone 7 vs. an iPhone 7+). So we designed a low-profile plastic VFO A knob that is big enough to get the job done. Another reason not to use a heavier knob is that the KX2?s VFO encoder is itself a compact unit that has a sleeve bearing. Weighted knobs should in general be used only with heavier, ball-bearing style encoders. On this encoder, a heavy knob would shorten the rotational life. Regarding adding a dimple: I?ve tried knobs this size with dimples and found that they were hard to use. A matter of taste and fingertip size, I guess. Meanwhile, the present knob can be ?spun? to a certain degree by putting light finger pressure on the rim. 73, Wayne N6KR From k9yeq at live.com Thu Mar 30 20:28:36 2017 From: k9yeq at live.com (Bill Johnson) Date: Fri, 31 Mar 2017 00:28:36 +0000 Subject: [Elecraft] FCC R&O approves 630m ham band In-Reply-To: References: <201703301937.v2UJb6DX016724@mail41c28.carrierzone.com> Message-ID: :-) 73, Bill K9YEQ -----Original Message----- From: Elecraft [mailto:elecraft-bounces at mailman.qth.net] On Behalf Of Fred Jensen Sent: Thursday, March 30, 2017 3:48 PM To: elecraft at mailman.qth.net Subject: Re: [Elecraft] FCC R&O approves 630m ham band How many watts into a rubber duck for 5 W EIRP? 73, Fred ("Skip") K6DGW Sparks NV USA Washoe County DM09dn On 3/30/2017 12:47 PM, Wayne Burdick wrote: > Working on a 472 kHz HT as we speak :) > > Wayne > N6KR > ______________________________________________________________ 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 k9yeq at live.com From jim at jtmiller.com Thu Mar 30 20:39:55 2017 From: jim at jtmiller.com (Jim Miller) Date: Thu, 30 Mar 2017 20:39:55 -0400 Subject: [Elecraft] 630m band for K3s Message-ID: Now that 630m is approved in many places including the US and since the K3s can output there how about making it a proper selectable band rather than accessible only by the TEST mode.

(The main receiver does not need to be silenced often, because one wouldn't be listening to the subreceiver if someone were calling.) However, it would be really useful to be able to see CW signals on the P3, with a 10 kHz span, when tuning the band with VFO B. As far as I can tell, the P3 only tracks VFO A, so nothing can be seen if VFO B is outside the span range. Is there a way to make it keep the VFO B cursor on the screen, in both the tracking and fixed modes, without setting the span wider? If worse comes to worst, I can use a foot switch to switch the audio between receivers, but I'd rather not. 73, Scott K9MA -- Scott K9MA k9ma at sdellington.us From n6kr at elecraft.com Thu Mar 30 22:04:28 2017 From: n6kr at elecraft.com (Wayne Burdick) Date: Thu, 30 Mar 2017 19:04:28 -0700 Subject: [Elecraft] New Amplifier Capabilities In-Reply-To: References: Message-ID: Someday.

References: <1460464554.1185471.1490927599133.ref@mail.yahoo.com> Message-ID: <1460464554.1185471.1490927599133@mail.yahoo.com> My wish list includes a mini hand mic without the spiral cable for hiking/SOTA applications. The KX2 is so small and light the stretchy mic cable often yanks the radio out of position - especially when you have it sitting on a rock on the ground. Just use the same cable as what is used for the audio cables, and make it 3 or 4 feet long. A smaller mic housing would be great as well. The MH3 is massive in relation to the KX2. I realize memory is probably very tight, but if we could somehow get 2 minutes of continuous recording, it would be possible to record a WSPR transmission and transmit it manually in the field without a computer/smartphone. I would also love to see the option to replace all the knobs on the KX2 with a low profile set, so the entire radio is more compact, and fits better inside of the various Pelican cases and carrying pouches. In the field I don't spin the knobs much anyway. If the hardware is capable, a dimmable backlight would be handy. I'm all for any new or more convenient portable antennas. Whether they're wire or compact loaded whips (like the MFJ-18xx series).? Compact battery charger for the KX2. The standard charger is huge.

I?ll port it to the KX3, too. There?s now a menu entry called ATU DATA, with two selections: SET 1 and SET 2. Each provides ATU settings for all bands (up to 32 segments per). I?m using SET 1 for home and SET 2 for field operation. I also changed the way the CLR function (OFS knob hold) works. Now, if you?re in either the ATU DATA or ATU MD menu entries, holding CLR only clears the network values for the *presently selected* ATU data set (on the present band). Thus you can arrive at your campsite, etc., select SET 2, then do a CLR on each band if you?d like, without messing up your SET 1 data. (Doing a CLR is a good idea with any new antenna on a given band. With fairly low-Q antennas, you may then only have to do an ATU tune at the middle of each band. The ATU always uses data for the closest of the 32 segments on each band that has non-zero data, even if there?s just one segment pre-tuned.) To verify that the ATU DATA feature working, I added another new function. While you?re in the ATU DATA or ATU MD menu entries, you can tap ?ATU? to see the present LC network values. It?s a little cryptic but still useful. The format is Lxx.Cxx.Nx, where: Lxx or Cxx = L or C relay settings in hexadecimal Nx = Network C in/out relay setting, either A = antenna side of inductor, or T = TX side. Someone armed with the KXAT2 schematic could write a little program that converts xx into microhenries and picofarads. I?d do it myself if I had the spare time. If anyone else would like to give the new firmware a whirl, please email me directly. 73, Wayne N6KR From jim at jtmiller.com Thu Mar 30 22:53:15 2017 From: jim at jtmiller.com (Jim Miller) Date: Thu, 30 Mar 2017 22:53:15 -0400 Subject: [Elecraft] 630m band for K3s In-Reply-To: References: Message-ID: and of course that would mean a XVTR IF of zero. jim ab3cv On Thu, Mar 30, 2017 at 8:39 PM, Jim Miller wrote: > Now that 630m is approved in many places including the US and since the > K3s can output there how about making it a proper selectable band rather > than accessible only by the TEST mode. > > This should only be a SMOP. ;-) > > 73 > > jim ab3cv > From ron at cobi.biz Thu Mar 30 23:13:23 2017 From: ron at cobi.biz (Ron D'Eau Claire) Date: Thu, 30 Mar 2017 20:13:23 -0700 Subject: [Elecraft] Amp Thoughts: 1000 watts or 1500 watts?

In some cases a dB or so CAN make a difference. Otherwise, why bother to put a ?dB noise figure GaAsFET pre-amp at the antenna just to overcome 2dB of feedline loss?

Hope it holds up. The lack of knob weight on this most amazing little rig is the only genuine physical design gripe I can come up with. would be nice if it was a slightly heavier and rubberized grip.. pretty tough with such as small knob though and may be cost prohibitive. Your solution make lots of sense to bridge the gap. a push button encoder to add another route to menus would be another afterthought. > ________________________________________ > From: Elecraft [elecraft-bounces at mailman.qth.net] on behalf of Doug Millar via Elecraft [elecraft at mailman.qth.net] > Sent: Thursday, March 30, 2017 3:29 PM > To: Elecraft Reflector > Subject: [Elecraft] KX2 Weighted Knob > > Hi, > Well, I might have done it.

Message-ID: <003701d2a9f0$e524b900$af6e2b00$@bigpond.com> Sorry if you have this more than once, but I cannot get the KX Yahoo group to post my messages. Good question Wayne, For me it's the KX2 battery, the space for internal battery is limited in size and original pack is difficult to source in VK. A larger bottom plate that would accommodate a larger range of batteries would be nice. Maybe even a AA cell holder. This would allow some flexibility when travel both by air and when using the rig on a multi-day walking trip. As for software changes, Using the OFS mode for Course tuning and the Main VFO knob for Fine tuning is great but this is at the expense of the DISPlay function. It would be great to leave the VFO B display set as DISPlay but still have the option to Course tune via the VFO B Knob, rather than changing the tuning rate of the Main VFO knob between course and fine when DISPlay is on. This would be similar to how the TEXT DECODE mode works, and would allow the operator to leave the DISPlay on Voltage, Clock or whatever they wanted and still have course tuning. Another advantage of this feature is it allows the Main VFO Knob to be locked thus reducing the Bump and QSY risk. Implementation could be via a new option in the Menu setup, VFO B display [VFO B or DISP] when in OFS Mode.

Qt5 plus some simple C++ is an awesome programming environment. Elecraft could only compile it for, e.g. Windows, but keep the source on Github so people can contribute if needed. But usually you don't have to apply any OS specific things, even the serial port is nicely abstracted from OS to OS.

I have tested the Rx and it seems to well (almost equal with the K3). But do not recall if the KX3 can transmit below 160m. Recall that the BC filtering was modified to increase sensitivity below 550-KHz. I'm guessing transmitting with the K3 is too complicated a modification in other than the TEST mode. Actually not hard to make a driver using a good old 2N2222 driven by the K3 at 1 mw. Follow that with transistors that will boost power into watts to be followed by a 100w amp. I think some experimenters should explore modifying 100w stereo amps to pass 472 KHz. remove the audio input and output transformers and use capacitive coupling. Might surprise how easy that might be. Any of you old tube guys ought to still find some tube Hi-Fi amps out there. Easy start antenna for 630m is the T antenna using an 80m or 160m dipole or inverted-V. Short coax feed shield to center conductor which converts it to a vertical with top hat. You will need a base loading coil to transmit but probably Rx with this simple set up. The NDB beacons operated from 200-518 KHz and used a 300-foot top wire with 60-foot vertical wire to the center. Wire was tuned with inductive coupling coils. There are still many NDB still operating in AK. I have copied one as far as 1000 mi out on the Aleutian chain. Use of a SDR is handy for Rx. There are 45 operators on 600m with the ARRL Experimental Group: http://www.500kc.com/ 73, Ed - KL7UW http://www.kl7uw.com Dubus-NA Business mail: dubususa at gmail.com From wrmoore47 at gmail.com Fri Mar 31 07:33:59 2017 From: wrmoore47 at gmail.com (Randy Moore) Date: Fri, 31 Mar 2017 06:33:59 -0500 Subject: [Elecraft] New KX2 firmware to test; provides two sets of ATU data and LC value display In-Reply-To: <827BD0B7-D161-4CEB-B217-1185C0A5FCA1@elecraft.com> References: <827BD0B7-D161-4CEB-B217-1185C0A5FCA1@elecraft.com> Message-ID: <3C489157-6C6E-4BF3-8B07-7B3E3D97EB89@gmail.com> Wayne, I would use this on my K3/KAT3.

Now, if you?re in either the ATU DATA or ATU MD menu entries, holding CLR only clears the network values for the *presently selected* ATU data set (on the present band).

With fairly low-Q antennas, you may then only have to do an ATU tune at the middle of each band.

For a long time that is going to rely on relatively clean audio. Even if automated translation in noise becomes possible, with the amount of noise, etc., on an amateur radio circuit, the additional degradation in going from digital to analogue and back is likely to be negligible. There is also a fundamental problem with machine translation in that the solution for the translation will not stabilise until the end of sentence, or later. Whilst a human also needs to reach this point for full understanding, they will have part processed the speech before they get there. In the general case, the machine translator cannot even start passing the translation on to the human until it reaches this point, so there will always be a significant extra processing delay, compared with understanding the language, directly. I would also expect any software or hardware that comes onto the market to have been designed for use with at least the telephone bandwidth of 300-3.4kHz, not the narrower bandwidth used for SSB radio. Even telephone bandwidth is not enough to accurately recognize sibilants (s, sh, h, etc.). The main case where direct digital is useful is for digital mode, where phase errors, which have no impact on speech recognition, may be significant.

(This feature will be added to the KX3 as well.) Below is the information needed to extract the actual L, C, and L-net configuration values from the information that is flashed on VFO A when you tap ?ATU? in the new ATU DATA menu entry. Wayne N6KR * * * While in the ATU DATA (or ATU MD) menu entry, tap ?ATU? to obtain the L/C/Net values. The displayed data format is ?LaaCbbNc;?, where: aa = inductance bitmap in ASCII hex format bb = capacitance bitmap in ASCII hex format c = L network relay setting: A = capacitance on antenna side T = capacitance on transmitter side Example: Suppose ?L03C12NT? is flashed. The network setting is shown by the last character (A or T; see above). Next, convert the L and C hexadecimal quantities to binary: 03 => 00000011 (L) 12 => 00010010 (C) Compare these values to the lists below, which show approximate L and C values for each bit of the binary word. In the example above, 00000011 for L means that two smallest inductors are switched in (.05 and .11 uH). Add these together to determine the total L value. Similarly, add up the selected capacitors based on the binary value 00010010. --------------- Binary Value ---------- 0 0 0 0 0 0 0 L, uH: 4.0 2.0 1.0 .5 .23 .11 .05 --------------- Binary Value ---------- 0 0 0 0 0 0 0 C, pF: 680 330 164 82 39 18 10 Note on L/C values: The ATU uses industry standard 5 % values for C, and approximately 5% tolerance on toroidal inductors. L and C are not exact but will be monotonic over the required range of about 3 to 5 elements for a given match. In addition, all ATUs have stray L and C that will result in selection of somewhat different values than expected. This effect becomes more pronounced as the operating frequency increases.

The center used to be at about 40 feet. About the time version 5.57 of the firmware came out, the mast supporting the center feed point broke and I re-rigged with the center at about 22 feet. (I hate debugging when there were two changes.) Measurement of the lowered antenna with a MFJ-259B antenna analyzer show 1.2:1 SWR match at 1.87 KHz with 2,5:1 and 3.3:1 at the band edges from the shack. Because of the mismatch at the band ends, I usually use the antenna using the KAT3A tuner installed in my K3. (I don't have similar figures for the higher antenna, but the SWR curve matches the computer model.) I used the antenna with modest success including 10 DXCCs and 41 US states confirmed. When I installed 5.57, I noticed significant power drops on 160M, stepping down from 100W to 25W and 50W. With the help of Elecraft support, we have concluded that the antenna is irritating the new firmware feature: K3 MCU 5.57 / DSP 2.88 / FPF 1.26, 2-16-2017 * FASTER RESPONSE TO HIGH REFLECTED POWER. The transceiver will now reduce drive more quickly when transient conditions cause excessive reflected power. This roll-back response does not change the set power level (PWR knob); instead, it reduces the drive to get below the reflected power limit. This means that once a better match is restored (such as when using an antenna tuner), the set power level will automatically be restored. When I backed off to version 5.50, 160M performance seems to have gone back to what it was. Measuring the open-circuit voltage on the antenna feed line with a oscilloscope shows about 600mV peak to peak. I estimate, based on eyeballing the trace and measuring other antennas, that about 200mV of that is 60 cycle hum. Elecraft support thinks this is enough voltage to affect the internal K3 SWR bridge. The voltage is most likely from AM broadcast stations. The strongest station, measured with the P3, is KLIV (5000W) about 8 miles from my QTH. So now, the question is what to do about the problem. Several things I have been able to think of are: * Use a broadcast band filter. DXEngineering has one that will handle 200W, but it wants 50 ohms impedance on both ends. Therefore it is recommended to install it between the power amp (internal to the K3) and the tuner (also internal to the K3). I might be tempted to insert one in the K3, but the tuner and power amp are connected through a header, not a simple cable I could reroute to install the filter. * Get a KAT500 and the filter. Expensive, but straight forward. * Sometimes the power remains at 100W when the internal tuner is in bypass mode, but not always. It might remain stable enough for QSO, but flipping back and fourth seems to be a pain. Does anyone have any suggestions?

Lots of good capacitor choices at HSC. Another suggestion though. KLIV is omni during the day, but strongly directional at night. This is quite common on the AM band. I suggest that you make your strength measurements at night. Depending on where you are, a different station may be stronger at night when you're working 160. Here's a link to the FCC website where you can look up technical details of any broadcast station. https://www.fcc.gov/media/radio/am-query And here's the listing for KLIV Notice the links near the bottom of each listing showing pattern and coverage area. The wild distortions in the coverage area are the result of varying ground conductivity -- the big thumb over the Bay is because it's sea water. https://transition.fcc.gov/fcc-bin/amq?list=0&facid=19531 Another thought, Bill. A horizontal 160M antenna at 20 ft is a real worm-warmer, and while 40 ft is better, it's still very low. If you can do some sort of counterpoise, a top loaded vertical, even if it's short, could work a lot better. Here are slides for the talk I've done several times about getting on 160M. It's mostly about antennas and counterpoises. You might have heard it. :) The K2AV folded counterpoise seems to work pretty well, and doesn't take a lot of space. 73, Jim K9YC On Fri,3/31/2017 2:50 PM, Walter Underwood wrote: > Use a series-tuned ?wave trap? on KLIV?s frequency across your feedline.

I really like my KX2, but, with respect, I'm unconvinced the HT use case is worth trading heavily against the more practical use cases. -- Christopher 73 de AI6KG On Thu, Mar 30, 2017 at 5:09 PM, Wayne Burdick wrote: > In response to various comments on the KX2 knob (today and earlier): > > Our goal for the KX2 was to make it really lightweight.

Along with the challenges inherent in having to manage two FT-817s to manage a satellite contact, there is also the relative degree of difficulty in managing the FT-817?s menu settings which can be very confusing to new users. On the other hand, in my opinion Elecraft?s menu management of settings is much easier to understand and implement, enhancing the user experience. In addition, the quality of user support provided by this forum is a significant service as well, enhancing the Elecraft brand. Bottom line is that a KX2 or KX3 style radio capable of 2M/70 cm with full duplex would be an awesome product as the number of amateur satellites in orbit will continue to increase over the next couple of years?
