[Elecraft] CW while in SSB mode
It must be right in front of me but I don't see in the manual or through experimentation... What are the settings to allow sending CW while in SSB mode? Thanks.

Re: [Elecraft] CW while in SSB mode
This control is far from intuitive. :-) Go to CONFIG menu item CW WGHT and tap the 1 key. Display should momentarily say CW +SSB (allows CW in SSB mode) or CW -SSB (disallows CW in SSB mode).

[Elecraft] [OT] Amtor activity evenings
Last Tuesday I started a European Amtor activity evening, with remarkable levels of activity. There were around 12 Amtor stations active on the 80m band, amazing considering the mode has almost died out. Maybe a similar event could be organised in the USA? The K3 is well suited to operating on Amtor with it's synchronous data mode (DATA A with -s displayed) and has no antenna relay to irritate users, or wear out with the constant tx/rx cycle. So if you have an old PK232, KAM, or whatever, and would like to use it again... 80m on Tuesday evenings is the time and place to give it a whirl. 73 Dave, G4AON __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K3 KComm PSK D / FSK D Question
I'm either missing something or I have a feature request for KComm, depending on whether I have misunderstood how to use the software! I've been looking for a contest / general purpose logger for data modes from the K3 that can make use of the K3's PSK D and FSK D modes for RTTY and PSK31, i.e. using the K3 to generate the RTTY or PSK signals and not the computer soundcard. This is something that, at least with my basic PC, the K3 seems to be much better at as well as eliminating an audio cable from the PC to the K3. KComm does this very well. On the receive side, there's a problem. I've read understand the reasons why KComm cannot yet use the decoded RX data from the K3 on the serial port (big shame, BTW). But even so, tuning PSK31 signals is very fiddly using the K3's CWT hopeless in a contest situation. I was hoping to be able to use the PSK engine and the waterfall within KComm to facilitate tuning in signals and for text decode whilst retaining the excellent FSK/PSK D TX arrangement that KComm has implemented. However, as soon as the soundcard option is ticked in the settings, the programme seems to now only allow TX also via the soundcard. So to my question: is it possible for KComm to use the PC soundcard for RX tuning and data decode, whilst retaining the K3's data TX capabilities via the serial port? I think even after it hopefully becomes possible to separate the K3's decoded text and radio responses on the serial port, some form of waterfall aid to tuning and band monitoring will still be extremely useful within a logging / control programme, then requiring an input to the soundcard anyway. At the moment, I use the MMVARI data engine for RTTY PSK31 RX, and KComm for TX. But, they fight for the serial port, they don't fit on the screen, you can't easily transfer data from an RX to a TX window etc. etc. It seems to me that KComm does almost all of this already if the above were possible (OK, the data engine needs to support RTTY too, but that's a next step; the K3 display will have to do in the interim as it's much better at tuning decoding RTTY). It is possible? Could it be inplemented? Any other thoughts or solutions?

[Elecraft] [K2]Crystal filters
Hello all, I'm at the end of my yearly K2 alignment and have come to the crystal filters part. Currently I have CW filters of 1.5K, 750, 400, and 250 with a side tone of 600Hz. On SSB I have OP1, 2.1, 1.8 and 1.6. I'd love some spectrogram screen shots showing how people have theirs setup. Mine are all pretty much centered between 300Hz and 2500Hz. I know Don, W3FPR says move the -3db low end shoulder of the bandpass to 300Hz but a screen shot would be helpful. I'm going to setup and use my RTTY filters for digi modes and need some guidance on suggested bandwidths and center frequencies. Thanks. -- R.

Re: [Elecraft] Single band QRP rig
My answer is tempered with a look at what it is that you want to do... when? The time of day becomes primary with the props being what they are now. With the MUF dropping near or below 7 mhz, in the evening.. maybe a look at 80 meter would be good. However, if all your operating will be daytime, then 30 meters becomes much more attractive. If you plan on going to bed somewhat close to after sundown, then 40 meters is your band. Focus on time of op, yields productive operation. If I had to have a single band rig... I would seriously consider the AT3 that Steve Weber has. oh.. it isn't single band well.. it is if you only carry a single band module. The mfj rigs are good little rigs, yet when I was looking at them, I figured that I would wind up buying two or three so.. hello Steve. You see, I had already chosen a K2, and wanted to spread my experience. The KX1 is a wonderful rig, and the K1 does wonders, and being exquisite with implementation, and add ons of bands is really easy. All of them are good. So, how to decide? I would look at the clock... then look at the clock again... choose two bands of preference for now then look at the options. Almost any of the rigs offered will do a respectable job, given a chance. Please don't tell me that SMT or SMD is something to shy away from either. That is not an option, for anyone any longer.

Mike Short AI4NS ai...@arrl.net -- For making QSO's, 40 meters has generally been the number 1 choice. It's usually open 24/7 (or nearly so) to somewhere regardless of sunspots and through all but the most gruesome solar flares. If you're in a reasonably populated area, 80 meters is a close second for making contacts, although it's closed except for very local short-skip during the day due to the high ion absorption at low altitudes until a bit after sunset. Still, you can make contacts for 50 miles or so during most daylight hours. And, at night, it can be a real DX band. The issue there is usually antennas. Many Hams today don't have the room to put up an efficient 80 meter antenna which really hurts their signals. To be as good as a half wave dipole at 35 feet on 40, you need 130 feet of wire at 70 feet up (or more) on 80. So a lot of ops live with a vertical, which can be good IF one has a really good set of 'radials' deployed, but most have to live with a serious compromise. In the past, my personal favorite for one-band operation is 20 meters. It's closed many evenings - especially if you're a night owl during the sunspot lulls - but the DX is surprising, even now. But you may well spend half a dozen evening hours tuning a dead band and a lot of operators have no patience for that. The reward for doing that is suddenly you get a call from a signal out of nowhere on a dead band half way around the world calling you - often with a 599 signal! That's 20 meters. I've had a lot of good rag chews with DX stations there until the 'scanners' catch on and a pileup demands we quit chewing the rag so he can exchange signal reports. One time I worked only 20 meters for three or four years with a homebrew 10 watt rig. It was a happy and memorable period. If you aren't interested in contests, 30 is a great compromise between 20 and 40. I'm not a contester so if I were to build a one-band rig today it'd probably be for 30.

Re: [Elecraft] Single band QRP rig
I would definitely opt for 40 meters. I've always felt that if I only had one band to operate on, it would be that one. 40 meters is as close to a 24 hour band as you will find in the HF spectrum. It also gives you a good variety of coverage, with DX being very possible much of the time. During daylight hours, 40 meters shortens up a good bit, but you can still cover a fairly large area geographically. 30 meters comes close, but doesn't quite hold up at night, and 80 meters doesn't hold up too well during the daytime. When conditions really get good, 30 meters, and 20 meters too, can be open much of the time. So you have to consider what part of the cycle we are in to some extent. Antennas can be a limiting factor as well. A 40 meter antenna is still fairly long (dipole), and really need some elevation, particularly when running low power. A vertical might be a better choice if you have a space or support problem.

Re: [Elecraft] K3 KComm PSK D / FSK D Question
I may be missing something, but I think it could work in the same way as KComm behaves now. Unlike other soundcard software, which simply decodes in the DSP at whatever frequency in the waterfall is selected, KComm retunes the K3's VFO so the signal is centred in the waterfall. Therefore it is always decoding at a known fixed frequency. There may be an offset from the TX frequency but it should be predictable and can therefore be compensated for. The quick test would be to see if the soundcard decoded text coincided with the K3's own decoded text. Unfortunately it's difficult to check because the K3 PSK31 text decode is disabled in DATA A. The usual caveats about misuse of AFC and NET would still be relevant. I can see how it needs to be implemented from a system perspective, but not being a programmer, I don't know how to do it! 73 Ian G4FSU 2009/2/28 Joe Subich, W4TV li...@subich.com Ian, So to my question: is it possible for KComm to use the PC soundcard for RX tuning and data decode, whilst retaining the K3's data TX capabilities via the serial port? Although it might be technically possible for KComm to be modified to use the PC soundcard for turning and PSK31 decode and the PSK-D mode for transmit, I do not thick you would like the results as the transmit and receive frequencies would quite easily diverge since PSK-D transmits at a fixed 1050 Hz tone frequency. Zero beat is quite critical with PSK modes. As little as 10 Hz deviation between transmit and receive frequencies can result in walking the band if AFC/Net are in use or no copy if the other station is not using AFC. 73, ...

The annual alignment is just my way doing preventative maintenance and staying on top of things before a problem does rear it's ugly head. This year I discovered some dust in the rig. I think it's caused by the two 80mm computer case fans I've got on the KPA100 heat sink. They draw air across the sink and exhaust straight up. Some canned air and a fine brush and she's cleaned. Never would have found that if I didn't open the case up once a year. While I've got it open I just check stuff. 73 David Pratt wrote: In a recent message, R.

The annual alignment is just my way doing preventative maintenance and staying on top of things before a problem does rear it's ugly head. This year I discovered some dust in the rig. I think it's caused by the two 80mm computer case fans I've got on the KPA100 heat sink. They draw air across the sink and exhaust straight up. Some canned air and a fine brush and she's cleaned. Never would have found that if I didn't open the case up once a year. While I've got it open I just check stuff. David Pratt wrote: In a recent message, R. Kevin Stover rksto...@mchsi.com wrote ...

[Elecraft] Main VFO knob wobble
Hello, My main VFO knob is starting to develop a slight wobble. There is no radial play, but a slight axial play and I can rock the knob on the shaft. I am hoping that it is just the screws coming lose and not the encoder bearing going bad. Am I justified in this optimism? It isn't noticeable yet when I use my forefinger on the outside of the knob, which is my usual way on the K3.

Re: [Elecraft] K3 QRPp
Lyle Dave, Thank you so much for your explanations. I realize all the efforts I have put in towards my 150 meter radial field had to work in my favor. I am on the ocean and my back yard is a salt water marsh. I use the first tall tree at the marsh's edge as the support for my 160 meter inverted-L. It is electrically long and I use doorknobs at the feed point to give me a 1:1 match at 1.830. I have 60 some 130' radials laid out with 1/2 of them on the marsh and the rest on the bog beside it. I have the same kind of L attached to the radial plate for 80M and in the center of the plate is attached a butternut HF9V. The get selected via an Ameritron remote coax switch. FWIW, I do extremely well on low bands with this for I'm forever hearing in contests how powerful my signal is yet I always adhere to less than 1500W out. CW I set at around 1,100 watts out in a contest just so I know my score is guaranteed to be legit. Several days ago I worked at the K3 stated 100mw level and was amazed by how many replies I was able to get on 160M 80M. I had started out at 5W and gotten several replies and then when I received a 579 from Wisconsin on 160, I dropped to the lowest the scale offered at 100mw and he gave me a 459. I called more CQs at 100mw and worked a NC, IA and MI back to back, to back. I wanted to go lower and try 10mw, even 1mw if possible but was not sure how to do this without possibly transmitting into the wrong output. I am on the road at the moment but will try your suggestions when I get back. Amazing what an advantageous antenna system will do. I entered the SSB contest for two hours last night just to give people some contacts/multipliers. The C6 I worked said he'd heard me earlier and took the time to tell me several sentences worth how powerful my signal was. The same for several VE stations and one from WV. I know the antenna is big in those reports but I also wonder how much using the K3 with it's compression played a part as well? Gary KA1J If I want to operate at say, 1 watt I believe all I have to do is adjust the power out and it will go from 100mw to 120W using the main antenna 1 or 2. Yes. If that is true, how does one select and use less that that? Set up the transverter band per page 39 in the manual (latest rev D-2). Use the XVTR OUT connector for the Tx output. Be sure to run the transmit calibrations routine from the K3 Utility for the milliwatt output. See the help in K3 Utility for details. If you want to force the radio to use milliwatt level output on the KXV3 without first setting up a transverter band, then set CONFIG:KXV3 TEST. See page 49. 73, Lyle KK7P __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Re: [Elecraft] 2nd receiver option K3
Why would you want to do one vs. the other? 73, Ken, K6LA / VY2TT If you're using the RX antenna for both receivers at the same time, you can just set the SUB's antenna to MAIN and turn on RX ANT. If you want to use the RX antenna on the SUB, but stick with ANT1/2 for the main receiver, set the SUB's antenna to AUX (after having tied it to RX ANT IN with a BNC 'Y' cable). 73, Wayne N6KR __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] [K3] Main VFO knob wobble
It's easy to see if it's the set screws. That rubber tire around the knob just slips off. You may have to work your fingernails under the edge closest to the front panel while pressing on the knob with your thumb(s) but it just slides off of the knob. Then you'll see the holes for the hex wrench to tighten the set screws.

[Elecraft] Weird EMI issue... part deux
OK gang, I don't know what to do at this point and you're my last line of defense before sending this rig back to Elecraft engineering for analysis. I'll sum it up briefly: This is rig #2730. I bought it in kit form, and assembled it myself. It has a sub receiver, 100w amp, KDVR3, KAT3 tuner, transverter, plus a full complement of filters on both receivers. I also have a single general coverage receive module installed on the sub receiver. This is the problem: I've noticed that when I'm tuning around 4.8 MHz to 5.3 MHz, I can hear EMI in the form of a motorboat sound whenever I turn a front panel knob. It's most apparent when spinning VFO A or VFO B knobs, but also occurs when turning the filter knobs. If I don't touch anything, no noise occurs. I can also hear this noise faintly when I'm around 3 MHz. There is no front-panel generated noise anywhere else from .5 to 54 MHz other than 3 and 5 MHz. Also, if I don't have the sub receiver on and I'm only listening to the main receiver, the EMI noise isn't as loud when the pre-amp is on. If I turn the pre-amp off, the EMI generated from spinning knobs increases in volume. When I spin a knob and hear this noise, I can also see the S-meter move in correlation with the noise; spiking at S-7 from time to time. This tells me that this is locally generated interference, and occurs somewhere within the K3's circuitry. Turning the pre-amp on or off has no effect on the sub-receiver; the noise is still present. Here's what I've done: I've replaced the SUBIN board because I thought it was only the sub-receiver being affected at one time, but it didn't help. I've also swapped mixers and synthesizers with no positive result. I've disassembled and reassembled the entire front panel 4 times already, and cannot find anything wrong. I've traced circuits on the sub receiver and SUBIN boards and everything checks out. I've also swapped TMP cables around with no improvement. I've also removed just about every module except the transverter and KAT3 hoping to eliminate a problem module, but the problem still remains. I've also checked every screw and washer throughout the radio, and they all match the assembly instructions. I'm starting to think that there may be an isolation problem with the main RF board at this point. BUT, since I was not able to test the rig without the KAT3 tuner or removing the transverter board, I cannot be 100% sure. Is there anything else I can check before sending the rig back to Elecraft??? Apart from this problem, I have not experienced any other issues with this radio. In fact, it works PERFECTLY well.. I should probably tell myself to live with this noise, but after spending 4k, I don't want too. Suggestions people?

It's most apparent when spinning VFO A or VFO B knobs, but also occurs when turning the filter knobs. I have a slight bit of noise when tuning only in that area. I believe it to be entirely normal. I recall Wayne saying somewhere that the DDS operated in the area of 5 MHz and that was synthesizer switching noise. In my case, the noise is about S1 on an S-meter that was calibrated to the XG-2 and is in abs mode. In my case the noise is only audible in the main Rx with VFOA or XIT/RIT when XIT/RIT is enabled ... or in the sub RX with VFOB or XIT/RIT when XIT/RIT is enabled. The noise is masked by band noise with an antenna connected. It is audible only from 4.900 to 5.100 and only noticeable from 4.940 - 5.050 unless one it looking for it. As you say, it is not present when the VFO or RIT knobs are at reset ... it is not a problem here. 73, ...

Re: [Elecraft] Weird EMI issue... part deux
Hello Joe, Thanks for the reply. So if I understand you correctly, this noise is coming from the synthesizer and is normal? From conversations with Elecraft tech support, I got the impression that this should not be occurring as they could not replicate the noise on their K3's. It also does not happen when listening to the sub receiver using the AUX BNC connector. It only manifests itself when listening to the main or sub receivers and using ANT1 or ANT2. I have noticed that if I come across a broadcast signal within that specific frequency range, then the signal will mask out the EMI completely, and I can't hear it until I tune past the station. It would be helpful if I could get a definite answer from the Elecraft engineers. So far, I have not heard anything from them. This noise is actually quite loud for me, and spikes at S7 on the Elecraft meter. 73, James KC2UEE -Original Message- From: Joe Subich, W4TV [mailto:li...@subich.com] Sent: Saturday, February 28, 2009 6:06 PM To: 'James Sarte'; elecraft@mailman.qth.net Subject: RE: [Elecraft] Weird EMI issue... part deux I've noticed that when I'm tuning around 4.8 MHz to 5.3 MHz, I can hear EMI in the form of a motorboat sound whenever I turn a front panel knob. It's most apparent when spinning VFO A or VFO B knobs, but also occurs when turning the filter knobs. I have a slight bit of noise when tuning only in that area. I believe it to be entirely normal. I recall Wayne saying somewhere that the DDS operated in the area of 5 MHz and that was synthesizer switching noise. In my case, the noise is about S1 on an S-meter that was calibrated to the XG-2 and is in abs mode. In my case the noise is only audible in the main Rx with VFOA or XIT/RIT when XIT/RIT is enabled ... or in the sub RX with VFOB or XIT/RIT when XIT/RIT is enabled. The noise is masked by band noise with an antenna connected. It is audible only from 4.900 to 5.100 and only noticeable from 4.940 - 5.050 unless one it looking for it. As you say, it is not present when the VFO or RIT knobs are at reset ... it is not a problem here. 73, ...

Re: [Elecraft] Weird EMI issue... part deux
Hello Gregg, If these are indeed pulses generated by the encoders, would replacing them solve the issue, or is this a design problem? Could this noise be masked out in firmware, or is it a hardware issue that can't be solved via software? I do recall hearing about some people having similar problems with their rigs on 6 meters. In my case, 6m is quiet with no EMI noise. What's troubling me now is that some people say this is normal, while others like the good folk over at Elecraft tech support cannot replicate this issue on their K3's. 73, James KC2UEE -Original Message- From: Gregg [mailto:w6...@bellsouth.net] Sent: Saturday, February 28, 2009 5:55 PM To: 'James Sarte' Subject: RE: [Elecraft] Weird EMI issue... part deux James: I suspect that what you are hearing is an artifact of the pulses generated by the tuning encoder. These pulses are audible on some K3s on 6 meters. The fact that they are not as loud with the pre-amp on is most likely due to an increase in the noise floor when the pre-amp is activated that somewhat masks the pulses.

[Elecraft] Elecraft CW Net Announcement
Good Evening, I just checked to make sure: Daylight Savings Time does not start until next Sunday. I was going to reinstate the forty meter net with the time change. So next week we can try 40 meters and see how it works. Conditions have not been very good lately; but there was a new sunspot this week. That sunspot is gone though I just read a solar stream hit the ionosphere yesterday. There is hope for better conditions ;) Let's check by running the net. Propagation charts and programs are one thing but actual contacts demonstrate real proof of conditions. This week had some sun but mostly snow and clouds. The forecast is for rain for the rest of the week. I hope so because it is starting to get dry in Oregon. This has not been a normal winter. I am glad of that in a way because I was not able to fix one last leak around my skylight. Next summer will give me another chance at getting everything repaired so I can continue my other renovation projects. If I don't get the roof fixed it does not make sense to work on the drywall. Now that winter is almost done I can estimate my wood used for the year. Looks like five cords will be enough for the entire heating season. Next year I hope to have a tighter and a more insulated house so I can use less wood and stay cozy. Please join us tomorrow evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP relay help) Sunday 2300z (Sunday 3 PM PST) 14050 kHz Stay warm, Kevin.

Re: [Elecraft] Weird EMI issue... part deux
Hi Gary, Yes, I suppose you're right. I have however tried rerouting all of the cables again, and made sure all the TMP connectors were inserted fully. That unfortunately didn't make any difference. I guess I'll just have to send it back to Elecraft for their engineers to diagnose. 73, James KC2UEE _ From: Gary Hvizdak [mailto:garyhviz...@cfl.rr.com] Sent: Saturday, February 28, 2009 11:21 PM To: kc2...@gmail.com Subject: RE: [Elecraft] Weird EMI issue... part deux James, My guess is that a design problem would affect all K3s.

Re: [Elecraft] k2 noise blanker
The noise blanker on my K2 is _very_ effective at eliminating the power-line noise in the area. Many time with it off the noise level is around S9 or higher and unless signals are very loud I just can't hear them. Turn on the NB, and the noise disappears and I hear signals. When I first got the K2 with the NB several years ago I had the same questions as you. Then the power-line noise problems started, and I quickly found out. I just wish whoever is responsible for the PL noise would be just as responsive in getting rid of them... I haven't found the setting yet for the K3 blankers that provide the same effect, but it should be there. Keep looking at various periodic noise environments, you will find a use for the blanker.

Re: [Elecraft] k2 noise blanker
Jack, On the K3, hold down the NB button until you see the DSP menu. Rotating VFO A will change the DSP settings while rotating VFO B will change the IF settings. When I come across power line noise for example, I'll usually set the IF setting to NAR1 and adjust the DSP setting until the noise usually goes away. 73, James KC2UEE -Original Message- I haven't found the setting yet for the K3 blankers that provide the same effect, but it should be there. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

[Elecraft] K3 power loss: Last settings forgotten
I just shut down the station by pulling the big switch and then turned it back on soon after. Of course I had to push the power button on the K3 to get it going again. Then I noticed what I never noticed before: The K3, while still tuned to the same 40m cw frequency, came up in LSB mode, with coarse frequency display. I pushed FINE and MODE DOWN to get back to cw and two decimals. Then I shut down the same way again, with the same result. Next time I powered down by pushing the K3 power button instead of the Big Switch. This time when I powered the K3 on again it remembered all settings. Looks to me like the K3 doesn't store all settings unless its power switch is pushed to shut down. Is this how it is supposed to work? I am running 2.76. 73, Erik K7TV __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

To all who responded, thank you. It was a firmware issue and loading the latest FW did the trick. I looked in the manual after the install and assumed it would work with older FW.
