Re: [Elecraft] Tom Hammond, N0SS, silent key
Tom was one of the first folks I met on the Elecraft reflector and helped me a lot with my K2. We corresponded on and off through the years. We worked in contests and even met at a TenTec Hamfest way back when. He was always friendly and upbeat. I knew of his health issues, but I didn't realize he had taken a serious turn for the worse.

I could be wrong, but assembled I think means that you send your K3 back to Elecraft and they install it for you. There was no assembly OF the K3 per se, other than putting it's parts in the K3.

Re: [Elecraft] RIBBON MICROPHONE
You can use a ribbon mic with the K3, but be aware that the pattern is bi-directional, and this model doesn't appear to allow the user to alter the pattern, unlike say...a poly-directional RCA 77Dx. Side rejection will be good but the amplitude response from rear-arriving sound will be the same as forward arriving. I wouldn't use this mic for that reason alone. You can connect the mic to the K3's rear-panel mic connector, using the same methods of interconnect for other balanced-output mics into the unbalanced input of the K3. Ensure that the K3's mic bias is deactivated. It should EQ nicely with the K3's internal equalizer.

Re: [Elecraft] RIBBON MICROPHONE
As the previous response indicated, there is no fundamental reason why you cannot use this microphone with the K3. However, as also indicated there are some drawbacks. As already mentioned, it appears this particular model does not have directional controls and so it will be bidirectional and sensitive to noise from the rear. And you should be aware that ribbon microphones are very sensitive to shock and vibration and can be easily damaged. They are also very sensitive to wind blasts, which if sufficient, can break the ribbon. And finally, they usually exhibit very strong proximity effects. You should be careful not to work too closely to this microphone or the bass response will be considerably enhanced which is not particularly helpful for SSB communication. I would work no closer than a foot from the microphone to avoid not only accentuating the base but also to prevent plosives or, as sometimes called, P pops which result from words having a P at the beginning and sometimes other letters such as B. In other words, a ribbon microphone should sound very nice if appropriate precautions are taken in its use.

Re: [Elecraft] KAT100 and KPA100 into EC case.
Mike, the comment about already having the KIO2 below is not correct. You currently have the KIO2 functionality in the KPA100, but you will lose that function from the KPA100 when it is mounted remotely. You will need the KIO2 or a suitable substitute in the base K2 top cover - the substitute will not give you computer connectivity, but will allow you to connect to the KPA100/KAT100. I strongly recommend you order the KAT100-1 to KAT100-2 conversion kit. It has the headers for the KPA100 connections as well as the full height front and rear panels for the KAT100. You will also need to order the EC2 enclosure. You already have the parts to assemble the connecting cable - build it just like the cable shown in the KAT100 manual. On 8/6/2011 12:33 PM, R.

[Elecraft] K Line Power Requirements
Thanks to Ron, Dick, Phil, Don and Jack responses. Very helpful!! RE: Specifications 1. Specifications. All came from the manuals! 2.Jack noted that the KPA500 manual shows 100 to 125 VAC or 200 to 250 VAC, 50/60 Hz, approx. 1000 VA 3. I calculated the current by dividing the VA by the VAC. I get 8.3 A for 120 VAC and 4.13 for 240VAC. Are my calculations correct? If so, then what is the relationship to the PA Current 20 A maximum and the PA Voltage 60 VDC nominal as shown in the manual RE: The K3PA500 does not run off the 13.8 VDC power supply 1. The K3PA500 does not run of the 13.8 VDC power supply but in my shack there is only one 120 VAC circuit so the current drawn by the K3 and the KPA500 have to be added together if I was to run the amp with the supplied 120 VAC power cord. 2. Because of this limitation and the admonition to not run the amp and rig on the same circuit I ran 240 to my shack to power my Ameritron AL-811H. This was a completely independent circuit. I ran my K3, Yaesu UHF/VH and amp (at 600 to 800 Watts) with no problems. BTW, when I ran the 240 to the shack I was able to then add a ground to the old, 1933, two wire 120 VAC circuit! 3. I am planning on running my KPA500 at 240 but wanted to calculate the current draw on the house 120 circuit since that is the supplied cable connection! In conclusion, I think a 25 amp supply would be more than adequate. I am leaning towards an Astron RS-35M. I like the absence of fans!!! I would like a smaller, lighter supply and would consider a switching supply. I will check the archives for recommendations but if anyone has an immediate recommendation I would appreciate it!

[Elecraft] XV432 Issues
I've just finished assembly of the XV432 kit, interfaced to a K3, and ran into two issues during alignment in Part VI, Filter Alignment. First, during CW key-down, the voltage at TP5 peaks immediately, then slowly drops off until it is a volt or more lower than peak. Immediately re-keying gets a somewhat higher voltage than at un-key, but not at the peak. Letting it sit a minute or two, then re-keying, gets the original peak voltage back. Output power does the same fade. Second, the 28 MHz filters don't seem to be aligning properly. I've set the cans at the set-points in the manual, but L15 and L16 seem to peak with the slugs out of the cans. L17 appears to peak ok, and the 432 filters both seem to peak fine. At the best point of alignment, I am getting less than 7 volts at TP5, vs, 10 required for full output. I've checked the K3 output, and the BNC cables, both are fine. The input section of the XV is easily able to overdrive the input to the 28 MHz filters, as evidenced by D10 and D11 lighting up at roughly half setting on the input attenuator. Max output from the PA is around 15 watts without lighting up D10 and D11. I've pulled and checked the five caps around the filters, all are within tolerance. Oscillator alignment was fine, 3v at TP1. I've tried re-aligning these three cans several times, including bottoming out the slugs and working back up, with no change. I'm on the air with it at the moment, and it seems to be working other than the low power output. Any thoughts?

Re: [Elecraft] KPA-500 with and without transformer buzz
I've experienced silent operation and operation with hum (what I'd call more of a transformer buzz). My mains are between 248V and 249V so I used the yellow tap per the table in the manual (the 231V to 250V tap). The HV then idles around 72.4V and on full power transmit, HV went down around 57V. In this configuration, full power transmit is silent, no buzz. But per the errata for the manual for best linearity HV should be 60V or higher during full power transmit. So, I switched to the red tap (the 211 to 230V tap). HV now idles at 80.0V and goes no lower than 64V on full power transmit. Linearity achieved, but in this configuration I get a noticeable transformer buzz. I opened the top and made sure everything was secure - no change. So, by changing the transformer voltage selection tap I've had both silent and with-buzz operation. At first I was concerned the buzz was an indication I was tapped too low for the high mains voltage but the 80V to 64V range is well within spec so I assumed I was ok to leave it that way. Still seems odd that I have to tap down when I'm so close to the max input voltage.

Hi Ed, Something is definitely not right there. I happen to have a PR-781 in my closet (it's for sale, if anyone's interested - I only use headsets now). I plugged it into my K3's rear input and configured: MAIN:MIC-SEL: rP.H MIC: 10 MAIN:VOX GN: 040 and it works great, with 5-7 bars on the ALC meter on voice peaks, without yelling. What are you seeing on the ALC meter? Try without VOX first, and make sure you're getting those 5-7 bars (use the XMIT button if you don't have an external PTT source).

Re: [Elecraft] [P3] P3 and K144XV
Hi Stan, Adjusting the ref level does not help. Looking at the IF output of the P3 the actual signal level is not changing when I switch between 6m and 2m. I hooked up my QS1R SDR and can see the signals fine when the P3 water fall display is orange when I am on 2m. I can not find a ref level that works. Radio is working fine on 2m as I can copy signals fine. When i disconnect the serial cable between the P3 and K3 the display is fine minus frequency and filter info of course. All the software is up today. Both of my K3s do this. Any ideas gang?? 73, tom n4zpt On 8/6/2011 11:13 AM, Stan Gibbs wrote: Tom, Sounds like your Ref Lvl is set too high. The color of the waterfall reflects the vertical position of the trace in the frequency display. If you reduce the reference level, the frequency display will return to a viewable position, and the orange waterfall will revert to blue. The reference level is per-band so you have to adjust it for each band you operate on. For my 2m setup the ref level is set at -145 dBm, which allows me to see the frequency trace when the pre-amp is on or off. - 73, Stan - KR7C -- View this message in context: http://elecraft.365791.n2.nabble.com/P3-P3-and-K144XV-tp5472582p6659797.html Sent from the Elecraft mailing list archive at Nabble.com. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html __ 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] Rear Panel Mic help ple
Ed, Definitely something wrong. How is your mic plug wired? You should have the AF connected to the tip and the AF return (or shield) connected to the shell. If it is connected as a balanced microphone with the AF connected to the tip and AF return connected to the ring, and a shield connected to the shell, connect the ring to the shell. The K3 mic input is unbalanced. Sorry, but I do not know how the Flex mic wiring is configured. 73, Don W3FPR On 8/6/2011 4:31 PM, Ed Stallman wrote: Iain , thanks for your input , I did look to be sure and I am plugged into the Mic in the back ...

Re: [Elecraft] XV432 Issues
Don, The manual doesn't state that you must adjust for 10 volts at TP5. Please read that section again. It does say that you should not exceed 10 volts at TP5 during the bandpass filter tuning. If the output goes above 10 volts, use the input attenuator R22) to bring the voltage down - perhaps in the vicinity of 5 volts, and then continue to look for the peak tuning point for each inductor that is to be adjusted. Go back over the peaking procedure 3 or 4 times. After you have peaked the bandpass filters, you will then adjust the input attenuator to produce the correct output (use an external power meter which is accurate at 432 MHz) while your selected maximum drive level is applied from your transceiver. After that (and while the transverter is producing 20 watts), you adjust R10 (Power CAL) so the LEDs indicate 20 watts. These 3 steps must be done in order - do not skip ahead or you will end up with frustration. Also, do not drive the transverter for too long at a time - particularly during the final power adjustments. Give enough break time to let it cool between adjustment trials. 73, Don W3FPR On 8/6/2011 3:27 PM, W3MW Don wrote: I've just finished assembly of the XV432 kit, interfaced to a K3, and ran into two issues during alignment in Part VI, Filter Alignment.

Ed, I would instead suggest that you open the TRS plug and connect the ring to the shell there. The ring is not connected in the K3, but a stereo jack is used.

Re: [Elecraft] Tom Hammond, N0SS, silent key
I first met Tom at the Elecraft booth at the Kirkwood, MO hamfest around 2000. He was vibrantly hyping the K2 which I had just started to build. He probably met 1,500 people that day. Through the years I'd call on Tom for help on various projects and he was always quick to respond. The first phone call he returned to me started off with hey Terry, you going to the Kirkwood Hamfest this year? My God, the man remembered me from that one meeting two years prior.

From the earlier post I expected missing screws, assorted hardware, Buzzing X'formers all sorts of small issues. Let me report that the unit is running on 220 Volts (Red Tap) Volt Reading is 80.4 Volts. No Buzzing, Not a Single Screw or Hardware Missing and Power Output at ranges between 20 - 30 watts input, output is between 500 - 600 watts. Other than an issue with the PA not transmitting on 6 Meters because of the use of the PR6 6 Meter RX Pre- Amp, I have had 0 Issues after just short of a weeks usage on all bands! I am using the KPA500 as a Standard PA Operation being keyed via the PA Key Line between the K3 and the KPA500. The PR6 Compatibility Issue will be addressed in the next Firmware Release 1.09.

Re: [Elecraft] XV432 Issues
Don, Thanks for your reply. It's great to get feedback here so quickly, especially as I managed to delay my question until a weekend. I understand the section of the manual regarding 10 volts at TP5. What I meant to indicate is that I cannot get anywhere near 9 or 10 volts at TP5 following the normal alignment procedure, regardless of whatever setting the input attenuator is at. I've followed the procedure by the manual, carefully, many times. Despite repeated passes through the peaking process (many more than three or four, I'm afraid), I cannot get over 15 watts output or over 7.5 volts at TP5 regardless of the input attenuator setting. I've since checked the coils to be sure I have the correct ones in the filter. K3 is set up for 1.00 power out, as instructed. The fact that the overload LEDs are lighting up at the high end setting of the input attenuator leads me to believe that the IF in from the K3 is ok, and that both pre-filter amplifier stages are working as intended. Adjustments of FL1 and FL2 are smooth and have a clearly identifiable peak, leading me to believe those are ok. I'm not seeing any voltage changes elsewhere in the transmit chain, and the rest of the device voltages look good. I made several attempts at alignment since your email, with no more success than earlier. As I am concerned that the PA module may be flaky, rather than fry the thing by continuing to tune, it's going back to Elecraft on Monday for them to have a look. I'll follow up here with the results.

Re: [Elecraft] XV432 Issues
Don, OK, and please understand that you will not necessarily obtain 10 volts at TP5. The voltage there is only relative, and is only used to identify the peak - once the tuning peaks have been found, the voltage there is no longer relevant. In other words, 10 volts at TP5 does not indicate full output, you must use a wattmeter that is accurate at 432 MHz to determine the 20 watt level. Can you measure the current that is being drawn while you attempt to get 20 watts output? If the current is excessive, there is a problem between the PA module and the antenna. Assuming that the efficiency is 50%, it will take about 3 to 3.5 Amperes at 20 watts output. As I indicated, a higher current indicates that there is a problem between the PA and the antenna output. OTOH, if the current is lower, That indicates that the PA module is not receiving adequate drive. If that is the case, try increasing the bias slightly to see if that gives any improvement. My experience with the specifics of the XV432 is limited, so if the problem is low drive to the PA module, it is best to email supp...@elecraft.com - unfortunately, they take the weekend off for a well deserved rest (we volunteers do not have that privilege). 73, Don W3FPR On 8/6/2011 10:49 PM, W3MW Don wrote: Don, Thanks for your reply.

Re: [Elecraft] K2 Info 232 error
Jason, During CAL PLL, Error 232 means that the firmware is not properly reading the frequency. Aside from the obvious solutions of not being on 40 meters, and forgetting to connect the counter probe to TP1, It could be an indication that the counter probe is not working properly, or not enough RF voltage is getting to the firmware IC to reliably count the frequency. Put the probe in TP1, tune to 40 meters, and enter the menu for CAL FCTR. Does the frequency indicated equal approximately 4913 kHz plus whatever frequency is displayed on the K2 dial? If it does, then the counter probe is responding correctly. If you instead receive a varying frequency, or all zeros, the counter probe is not working properly. If you do not get a proper reading at TP1, then put the counter probe into TP2 - you should read the BFO frequency which should be somewhere between 4912 and 4916 kHz (depends on mode and filter selection). 73, Don W3FPR On 8/6/2011 8:34 PM, Jason Morgan wrote: Hello everyone, Well I am to the point of VFO Linearization in my assembly of the K2.

Re: [Elecraft] XV432 Issues
Don, The overload LEDs are a different situation from your tuning/power out situation. Sometimes the overload LED indication is the result of noise getting into the XVxxx firmware chip. The cure for that noise is to connect a capacitor between the collector and emitter (ground) or Q2 on the front panel board. Any value between .001 and .01 uF should do nicely. Of course, if you are driving the XV432 with a non-elecraft transceiver, it could be that the overload condition is real - if the XV432 (or any XV series transverter) detects RF before the Key-In signal is active, it will cause the overload condition. I recall you are driving the XV432 from the K3, so I would attribute the LED flashing to a noise condition on the overload signalling line, and the capacitor should calm it. 73, Don W3FPR On 8/6/2011 10:49 PM, W3MW Don wrote: Don, Thanks for your reply.

[Elecraft] Elecraft CW Net Announcement
Good Evening, On July 27, 2003 I worked the twelfth operator to check in to my little net. I was very green at the job, this being only the sixth time I had run them and was basically playing it by ear. Then Tom Hammond arrived. He helped me organize the nets a little differently and then called them for me as a relay station and then as an alternate net control. He worried in his emails to me that he was taking over. I told him not to pay attention to that thought and keep helping me get better. For many years he did so; assisting me in my skills at NCS and in CW. I had heard about the OzarkCon QRP get together and thought I could travel there. I told Tom and he was happy to find a way to get there. I flew to Oklahoma City to meet my mentor KL7V, Sam Binkley (now N4SAM). He had been helping me with CW since I could barely spell 'cat'. He had taken me from a very shaky 5 wpm to over 20 wpm in daily hour long skeds which made my hands shake and my brain weary. He graciously welcomed me into his home for the night and then we (Sam, his wife Marijo, and I) drove to Joplin, Missouri the next day. I had just taken my gear to the room after checking in and saw a strangely familiar silhouette which gave me a clue that Tom was there. I walked up to him and started a conversation like we had known each other for years; well, because we had. Then Jeri gave me a hug in greeting and we were off. She was about to tell me something when Tom shushed her. He wrote a quick email to Wayne who gave his permission. That is when Tom told me about the K3. The first person to know about it at OzarkCon. He gave me many of the design details on a flash drive. I still have those somewhere and most of the details came true. For the next couple days I tagged along behind him and watched and listened. I sat down for a few presentations and was accosted by folks happy to meet me. ECN does open doors for me. I also got to listen to a group of banjo pickers, fiddlers, and story tellers which made it hard to leave. Sam found me almost asleep sitting in a chair leaned against the wall as the folks played on to tell me he was off to bed. He knew right where to find me. I had a great weekend there at OzarkCon with the two most important mentors I have had in amateur radio. I got to know Tom face to face as well as I had known him on the air and via email or phone conversations. He was just as great in person as he was via the other mediums. Listening to him teach was also enlightening and I have used those lessons while doing my own teaching for the local ECOM group. Thank you Tom Hammond for all the good times, for all the lessons, and for all the fine memories. Thank you for helping me with ECN for so many years. Telling you that you will be missed does not plumb the depth to which you have touched my life. Thank you old friend.

Re: [Elecraft] XV432 Issues
L Have a great day, Dale - WC7S -Original Message- From: Don Wilhelm w3...@embarqmail.com Date: Sat, 6 Aug 2011 21:15:40 To: w...@earthlink.net Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] XV432 Issues Don, The manual doesn't state that you must adjust for 10 volts at TP5. Please read that section again. It does say that you should not exceed 10 volts at TP5 during the bandpass filter tuning. If the output goes above 10 volts, use the input attenuator R22) to bring the voltage down - perhaps in the vicinity of 5 volts, and then continue to look for the peak tuning point for each inductor that is to be adjusted. Go back over the peaking procedure 3 or 4 times. After you have peaked the bandpass filters, you will then adjust the input attenuator to produce the correct output (use an external power meter which is accurate at 432 MHz) while your selected maximum drive level is applied from your transceiver. After that (and while the transverter is producing 20 watts), you adjust R10 (Power CAL) so the LEDs indicate 20 watts. These 3 steps must be done in order - do not skip ahead or you will end up with frustration. Also, do not drive the transverter for too long at a time - particularly during the final power adjustments. Give enough break time to let it cool between adjustment trials. 73, Don W3FPR On 8/6/2011 3:27 PM, W3MW Don wrote: I've just finished assembly of the XV432 kit, interfaced to a K3, and ran into two issues during alignment in Part VI, Filter Alignment. First, during CW key-down, the voltage at TP5 peaks immediately, then slowly drops off until it is a volt or more lower than peak. Immediately re-keying gets a somewhat higher voltage than at un-key, but not at the peak. Letting it sit a minute or two, then re-keying, gets the original peak voltage back. Output power does the same fade. Second, the 28 MHz filters don't seem to be aligning properly. I've set the cans at the set-points in the manual, but L15 and L16 seem to peak with the slugs out of the cans. L17 appears to peak ok, and the 432 filters both seem to peak fine. At the best point of alignment, I am getting less than 7 volts at TP5, vs, 10 required for full output. I've checked the K3 output, and the BNC cables, both are fine. The input section of the XV is easily able to overdrive the input to the 28 MHz filters, as evidenced by D10 and D11 lighting up at roughly half setting on the input attenuator. Max output from the PA is around 15 watts without lighting up D10 and D11. I've pulled and checked the five caps around the filters, all are within tolerance. Oscillator alignment was fine, 3v at TP1. I've tried re-aligning these three cans several times, including bottoming out the slugs and working back up, with no change. I'm on the air with it at the moment, and it seems to be working other than the low power output. Any thoughts?

[Elecraft] Elecraft Customer Service
I spent over an hour today (SATURDAY!) on the phone with Dale Farmer at Elecraft, who was resonding to an email I sent THIS MORNING!. My K3 100 W PA seems to not be working, and after trying everything else, it will go back to Elecraft on Monday for testing and/or replacement. No need to start a new thread...I just wanted to share this fantastic Customer Service experience! 73, Bill N4IEZ / F4WAE bdrob...@yahoo.com __ 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
