[Elecraft] WA3WSJ on AT Today 11/11/2004
Hello all, Seems like I was off with my UTC times- gets me every time. I plan to start operating around 11am EST or 1600utc and operate for an hour or two. Then hike the two miles back down the mountain. The tough part is hiking up! Look for me around the qrp frequencies on 40m and 20m. 72/73, Ed, WA3WSJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2: No recieve/power out on 20M thru 10M
Marc, What were you using as a signal during the 'cheap and dirty signal tracing'? If you were using an antenna lead and off the air signals, remember that the bands have been rather dead the last couple days - and more so on 20 meters and up in the evenings. Now that you have done the signal tracing (I assume in receive) and have determined that everything from D6/D7 to the audio is working, try the reverse using the RF probe while attempting to transmit at low power (about 2 watts) into a dummy load. You should see some drop in level from D6/D7 through the bandpass filters, but sufficient to measure. You can easily do a comparison from band to band. The output of the pre-driver stage (collector of Q5) is easy to reach on the top of the RF board - the collector is connected to the case. It is true that there is nothing in common to all those bands in the bandpass filters. As a totally wild guess, there might be some failure in the T/R switch that would convert something to a low pass filter (but that is a real stretch). Could it be that your prior efforts misaligned the bandpass filters for those bands while attempting to align them in receive state? You should be able to peak the bandpass filter during transmit (TUNE or TUNE/DISPLAY) with the RF probe on the collector of Q5. If you can find any peak at all on the bandpass filters, it is likely to be correct and you can rule out the bandpass filter area as the problem (or verify that is really where the problem lies). 73, Don W3FPR - Original Message - From: Marc Glade [EMAIL PROTECTED] To: W3FPR - Don Wilhelm [EMAIL PROTECTED] Cc: elecraft@mailman.qth.net Sent: Thursday, November 11, 2004 2:59 AM Subject: Re: [Elecraft] K2: No recieve/power out on 20M thru 10M Well, after following Tom's (N0SS) Cheap 'N Dirty Signal Tracing Guide it would seem that the problem does fall within the band-pass filter as injecting a signal at D6 works fine but at W6 hardly anything comes through for the aforementioned bands. Now I'm even more confused though as I don't see how one fault can cause issues on 20M-10M, but leave 30M-160M unaffected. That would leave me to believe that there are multiple faults in the band-pass filter which while possible, strikes me as very odd since everything was originally working fine and the now affected bands all started showing problems at the same time.

I suggest that one of the few things that could cause such behavior is the VCO. Use CAL FCTR with the probe in TP1 and check the VCO frequency on those bands. The frequencies should be close to those listed in the VCO Table of the K2 Schematic Key (appendix B of the manual). Also, build the RF Probe and check the VCO voltage as indicated in page 10 of the Troubleshooting section (Appendix E). 73, Don W3FPR - Original Message - From: Marc Glade [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Wednesday, November 10, 2004 1:23 AM Subject: [Elecraft] K2: No recieve/power out on 20M thru 10M I am the proud owner of K2 #4360. When I first put the unit together everything checked out smoothly and there were no issues. I have since added the KSB2, KIO2, KAT2, K160RX, KNB2, K60XV, and KAF2. No issues appeared to arise after adding the modules. I had to set the K2 aside for a month due to other commitments and upon returning to it about a month ago I noticed I had no power out on any band. A quick check and replacement of R50 solved this. Except now I noticed that on 20M thru 10M with a slight exception on 15M I still had no power out and also that even with max AF gain the signal from a connected N-gen was barely perceptible. 15M is a little different in that I can get a max power out of 1.5W on that band and receive is also a little better but not by much. On 160M thru 30M the rig functions perfectly fine. I have tried re-aligning the bandpass filters multiple times to see if that was were the problem was but could not resolve the issue. I have spent hours looking over the rf board with a magnifying glass and a dmm trying to find a fault or bad solder joint but haven't found anything. My knowledge in this area is limited and I feel like I've run into a brick wall with this issue. If there is anyone that has any suggestions I eagerly await them.

[Elecraft] re: KX1 low power out
Tim Hodges [EMAIL PROTECTED] From a 12.5V power supply I am seeing just around 2.5W measured with a scope into a dummy load (as well as other power meters). Tim : I don't believe that this is out of the range of possibilities w.r.t power out for a radio that is functioning ok. What I have found is that 13.8V vs 12.5V makes a difference in output so I suspect that you are probably getting in excess of 3W out at 13.8V. I originally had similar concerns with my rig but finally I concluded that a difference of .5 to 1W is almost indiscernible at the receiving end so I stopped worrying about it and started making QSOs and enjoying the rig. I often run my KX1 off of a 10 pack of AA NiMH cells and this gives me about 13.6V dc when fully charged. This puts me in the 3+ watt range on all bands except 20M which is usually a bit below 3W.

FW: WG4S: RE: [Elecraft] Anyone know how an MH2 works?
Well, the Heil Hospital page is for returning (at $12 or more) for them to repair. I couldn't find any parts on the site - It says to call them if it's not listed. Of course, they don't answer (actually, it's been busy for quite some time). The RatShack 270-090 sure looks identical. I'll just run that. Thanks for the voltages. Now I know the old element was toast.

Hi Dan, You might have a bad mic or mic connector or cable problem. The electret element in the MH2 draws very little current, so it should not load the 5V on the AF wire but slightly. I see about 1.7K to 1.5K to ground between mic pins 1 and 7 on two different MH2 mics I have here. On my KSB2, P1-5 has 5.0VDC without the MH2 connected, and 4.0VDC with it plugged in. Heil handles QC problems with their mics directly. If you need a replacement MH2, go to his website and fill out the Heil Hospital form and he'll take care of it asap. http://www.heilsound.com -- 73, Gary AB7MY = [EMAIL PROTECTED] Elecraft Technical Support -Original Message- From: Dan Barker [mailto:[EMAIL PROTECTED] Sent: Thursday, November 11, 2004 4:47 AM To: Gary Surrency Subject: FW: [Elecraft] Anyone know how an MH2 works?

Is that right? Pulled the mic apart. No shorts, all lines ring out. The element looks to my DMM to be a dead short. Is that right? Millampmeter inline with a 11K pull-up and a 9v battery shows .7 ma.

Re: [Elecraft] 10/12M Low Output Question
Thank you Eric and Mychael. Unfortunately, I seem to have mistaken the problem - I have problems at 20M and up (and a different dip at 4MHz). My T2 looks fine and was already off the board but I raised it a bit more with the green tuning tool, and re-peaked the 10M L and 12M C. I have done a full sweep of W and A vs F and found that I have low output on 20 meters and higher, and an anomaly at the top of 75 meters. See http://wa5znu.org/log/2004/11/k2-power.html for a graph and table. I get 10W out for 2A on 14.0MHz and 5.8W out for 1.68A at 14.35, into a dummy load right at the BNC, as measured by the KAT2. 17M is about the same but it goes down from there. The 75M dip could be something else, as the current is high there for its low output. I guess my next step is a full-band re-alignment of the BPF followed by signal tracing with the RF probe as Don recommended on another post. Leigh.

[Elecraft] 5 turns for T3 in K2 revisited...
I see the current manual instructs the builder to wind 5 turns on T3. I didn't see any mention of changing from 10 turns to 5 turns in the AtoB mod so my #1117 still has a 10 turn bi-filar winding. I'm get 12-18W output on all bands except 160M which is down at 9W. I'm wondering if rewinding T3 would be an improvement or a waste of time?

[Elecraft] WA3WSJ: The Best Laid Plans - Fail!
Hello all, I left the house this morning at 9:25AM EST and arrived at the Hamburg Reservoir Parking Lot about 9:50 and started hiking up the steep 2 miles to Pulpit Rock on the AT. By 11:00AM EST I was looking down over the valley from Pulpit Rock at an elevation of 1582'. I went over to the observatory next to the rock and set up my gear. First problem: I forgot my 20 PVC support rod for the vertical. No problem, I just grabbed a rock and dig out a small hole in the grass. I then placed the bottom of my VBWFPA in the hole and supported it with my HWPS-KIT or guy kit. I then pulled my K1 from the backpack and rolled out 50' of coax to the antenna. Second Problem: I tried to connect the PL-259 coax connector to the coil, but the coil has a BNC connector on it. I looked in my backpack and antenna case, but no adapter--- GAME OVER! I packed up the radio gear and Trevor and myself had a nice lunch on the mountain. He bummed half my lunch off me and drink about .75L of water. He's such a bum, but I love hiking with him. We then took in the view again from Pulpit Rock. I noticed the trees below the mid-point on the mountain still had leaves and color on them, but the trees above that point were bare. I met a nice woman who was day-hiking alone and we chatted for about 15 minutes. After the chat, it was down the mountain and back to the truck. We had a great time up in the mountains, but I wish I had made a few contacts. It still was a great day and the weather was beautiful up there. Maybe next trip I won't forget some needed radio gear- hi! 72/73, Ed, WA3WSJ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] How to set up SSB
I've just gotten my MH2 working again with a RadioShack 270-090 element. I have no idea if that's the right part, but it appeared identical to the Heil part, and the o'scope says about 120 mV p-p when I talk normally (Measured at pin 5 of the SSB adapter - should be the same as mic connectory pin 1). Anyhow, I sold my other rig years ago as the K2 was all I appeared to need. I'm wondering how to deal with on-air reports of horrible audio, almost unreadable without hearing what I sound like. Ideas: a) Borrow an SSB rig and fix my K2. b) Try stuff randomly on the air and hope the other ops give consistent info. I'm not sure how much trouble a) would be, but it's most likely the best way. I wonder what the shipping would be to borrow an extra rig from someone? Any spares out there? b) should work, but I have SSBA-1, SSBA-2, SSBC 1:1, SSBC 2:1, SSBC 3:1, SSBC 4:1, the VFO (how to tune someone whose voice you don't know) and of course, the BFO. Varying all of these in an organized way is going to take another receiver or someone VERY patient on the other end of the aether. Ideas? Hey, anyone know of an Internet receiver I can listen through? That might work. Only thing I could find in the archives is http://www.smeter.net/ and it's off the air.

Re: [Elecraft] K2 #4472 new builder question on 4 mhz alighment
Jerry, To properly tune WWV to 'zero beat', do the following: Set the K2 to LSB and adjust the frequecy until the tones transmitted by WWV occur at 500 or 600 Hz (they alternate each minute). I use Spectrogram with markers set to 500 and 600 Hz to use as an aid. You can get close by tuning until the voice announcements sound about right, but I can't seem to get any closer than about 40 Hz that way - that is why I use Spectrogram. The 1000 Hz tone is transmitted for only one second at the minute interval, the 500 or 600 Hz tones are transmitted for about 45 seconds (except for some silent minutes). There is more information on my WWV zero-beating technique and using the N6KR method to set the reference on my webpage www.qsl.net/w3fpr - look for the article on K2 dila calibration. 73, Don W3FPR - Original Message - Just finished the basic K2 and all seems ok,, but...

[Elecraft] K2 #04506 is alive and well
Hi, Am Pleased to announce that K2 # 04506 is all finished and waiting for it's first contact. ( Later this evening) The build was done over 4 leasurely days. Everything was present, thanks to Christine (who packed the modules) and it was a no-hassle build. It's kinda nice to have a K2 with pristine boards, instead of having odd components sticking out from the A to B mods that were done on my original series A K2 ( #2204)(I'll have to leave the lid off for a while :-) It never fails to amaze me that such a complex kit can be assembled to specification by almost anyone. It certainly speaks volumes for the design team One thing I tried this build, was using very thin resin cored 60/40 solder ( 0.56mm). It was absolutely marvelous. The flux residue was almost non-existant, and the amount of control I had over each joint was fantastic. Apply the iron tip and solder together and start feeding the solder as the hole fills. Any fillets on joints were small, and over-all it makes for a very tidy job.

RE: [Elecraft] K2 #4472 new builder question on 4 mhz alighment
Hi Jerry, What do I adjust ? If i adjust C22 nothing changes. C22 and the 4 MHz oscillator is used when you calibrate the K2. First you set C22 using CAL FCTR, then you run CAL PLL and CAL FIL so that the MCU can learn about the BFO and PLL reference oscillator settings by comparing those to the 4 MHz oscillator. The rest of the time, C22 and the 4 MHz oscillator is not used as a reference oscillator, so nothing happens when you change C22. You can set C22 using CAL FCTR, but you have to run CAL PLL and/or CAL FIL again in order to make any change in tuning. 73, Michael, AB9GV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] 10/12M Low Output Question
Following Eric's directions to measure current draw, I realized that I had low output on all high bands, not just 10/12m. Using the TX signal tracing procedure in the manual, I isolated the problem to the TX mixer buffer amplifier, and found it. Now I have plenty of output on all bands. Thanks for all the help Eric and Mychael, and for the great troubleshooting in the manual! Details for the record: U9, the TX mixer output buffer, showed approximately unity gain on all bands. I wicked and redid the solder joints of U9, to no avail, so I decided to check the buffer circuit components. Sure enough, I had neglected to install C150 on the bottom of the board. I even found the 330pF capacitor in my bag of parts left over, hi hi. C150 provides the RF coupling to ground for voltage divider in the feedback loop, thus setting the minus input of the op amp roughly equal to its output, making it roughly unity RF gain instead of 11:1. I guess below the middle of 20M or so, the mixer output itself was enough to drive the output stages. 73, Leigh. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Re: Is there a K3 coming - Not at this time.
Hi Eric, Thank you very much for your informative advice. Although I fully apprecipate the great performance of K2, this nice small rig seems not very popular in Hong Kong. Perhaps, local hams are just interested in multi-function rigs instead of high performance one. I would just wonder whether there are hams from Mainland China in this reflector who can advise K2's presence in PRC.

Re: [Elecraft] How to set up SSB
Dan, You could try using the microphone direct into a tape recorder if the mic's response is the primary question. If you are referring to filter adjustments to match your voice, I think more emphasis than necessary has been placed on refining the frequency range. If you have set your FL1 BFO so that the lower frequency -3dB corner of the SSB passband is at 300 Hz, you will be presenting the best frequency response for communications use. Some exceptions do occur, but that is not the norm. OTOH, if you have questions about overloading and clipping and the effects of compression on the fidelity of your voice or evaluating the response of that particular microphone with the K2, listening on a separate receiver is the best way to answer those questions. Of course, you can trust to another ham who knows your normal voice and has a receiver adequate to evaluate the signal - be certain that you are not overloading the receiver if that person is a local. As has been mentioned in a prior post, a simple DC receiver can be used to tell you what your signal sounds like. DC receivers have all filtering done at audio, and have potential to provide the best fidelity. 73, Don W3FPR - Original Message - I've just gotten my MH2 working again with a RadioShack 270-090 element. I have no idea if that's the right part, but it appeared identical to the Heil part, and the o'scope says about 120 mV p-p when I talk normally (Measured at pin 5 of the SSB adapter - should be the same as mic connectory pin 1). Anyhow, I sold my other rig years ago as the K2 was all I appeared to need. I'm wondering how to deal with on-air reports of horrible audio, almost unreadable without hearing what I sound like. Ideas: a) Borrow an SSB rig and fix my K2. b) Try stuff randomly on the air and hope the other ops give consistent info. I'm not sure how much trouble a) would be, but it's most likely the best way. I wonder what the shipping would be to borrow an extra rig from someone? Any spares out there? b) should work, but I have SSBA-1, SSBA-2, SSBC 1:1, SSBC 2:1, SSBC 3:1, SSBC 4:1, the VFO (how to tune someone whose voice you don't know) and of course, the BFO. Varying all of these in an organized way is going to take another receiver or someone VERY patient on the other end of the aether. Ideas? Hey, anyone know of an Internet receiver I can listen through? That might work. Only thing I could find in the archives is http://www.smeter.net/ and it's off the air.

Re: [Elecraft] K2 #4472 new builder question on 4 mhz alighment
At 05:30 PM 11/11/2004, jerry wrote... Anyway, I am now using Spectrogram and I have the Yaesu set for Lower SB and receiving the tone of WWW (10MHZ) at the 1k mark, the display on the MP reads 10001000 Hz. On the K2, using LSB , the display reads .84 and the tone of WWW (10Mhz) at the 1k mark. So far, so good. What do I adjust ? If i adjust C22 nothing changes. All other adjustemts I had no probles. Yes, you have to adjust C22, but nothing will change after you do until you run CAL PLL, then CAL FIL again. C22 affects the 4 MHz timing for the control processor, which handles the frequency counter function. When you do a CAL PLL and CAL FIL, the frequency counter is measuring VCO and BFO frequencies and storing the settings in a lookup table. From then on the table is used. Adjusting C22 without then running CAL PLL or CAL FIL doesn't do anything useful. Following the instructions below will get you very close. This is from a year old post by Wayne. In my experience, you actually want the VCO set about 10 Hz lower than the BFO to the most accurate readings. Here's the procedure. It requires revision 2.XX firmware, and assumes you have already done Alignment and Test, Part II, at some point. The K2 should also be allowed to come up to room temperature. 1.Tune in a signal at a known frequency. Use one that's at an *exact* kHz boundary, so you can easily see when the VCO and BFO readings match in step 2. (I use WWV at 10, 15, or 20 MHz.) Use USB or LSB mode rather than CW, so that there will be no CW receive offset. In the case of a K2 I was calibrating, the VFO read 1.17 when the signal was tuned in perfectly. If it had read 1.00, no further improvement would have been possible. TIP: Zero-beat the carrier precisely, or listen to a voice signal and adjust the VFO for the best quality. The more accurately you tune in the signal, the more accurately you'll be able to set C22, below. 2. Run CAL FCTR. Now alternately move the K2's internal counter probe between TP1 (VCO) and TP2 (BFO), adjusting C22 in small increments until the kHz and Hz digits at the two test points match as closely as possible. In my case, the two readings matched at 14913.60 and 4913.60. The difference is exactly 1.00--the frequency of the on-air signal. 3. Put the counter probe on TP1 (VCO), switch to 40 meters, and run CAL PLL. 4. Put the probe on TP2 (BFO) and run CAL FIL. For each operating mode, vary each filter (or BFO) setting up 1 count, then back down, to force the K2 to take a new BFO measurement for each and store it in EEPROM. The VFO dial should now be very well calibrated. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] listening to yourself
WG4S mentioned a dilemma I have had many times over the years. Even with readily available receivers, I can't really judge how I sound to myself locally all that well. I always want to hear myself over an RF link. I can always hear artifacts of keying or 'phone adjustments better when there's a few miles of tropo path ... no, I don't know why. The best way I've found is to simply ask a local ham to listen for me on 80/75 or 10 groundwave, depending on the time of day. In the case of WG4S, there are 22 other listed hams just in his town alone! so, doing this should be a snap for him. Call one, and set up a time so that either the transmissions can be recorded or, even better, simply have the other guy (or gal) hold their telephone up to the speaker! Members in our local club do this sort of thing regularly. In fact, lately we've been meeting in the evenings on 28.170 with slow CW for the newbies who want to just improve their code. Nice, quiet groundwave on an otherwise dead band is great for this! __ Do you Yahoo!? Check out the new Yahoo!

[Elecraft] crystals and radio names
... thanks to all for the advice on getting the crystal filter uprade ... seems like my early K2 had a well-matched set to begin with ... On another note, what is in a name? The K2 is named after the mountain, and I guess the K1 is, too. (See http://www.jerberyd.com/climbing/stories/k2 for a great article.) If there is to be another Elecraft radio, such as the long anticipated general coverage receiver I hope they make someday, perhaps it can be named the McKinley or, better, the Mitchell after the respective mountains. Or, maybe after a great lake, say, the Huron. Why a large body of water? Because the rig should have a great *sound.* groan Okay. I apologize for that. P.S. Where did Nils go?
