You may have broke the DSP firmware by keeping a key pressed too long.

Re: [Elecraft] K3 Problems
Until you appreciate that the K3 front panel buttons are all totally corrupted then any cure to this problem cannot be found. Sometimes the encoders on the four rotary/pushbutton knobs to the left of the main VFO knob stick, and cause the problem of nonresponsive buttons. Try rotating/pushing these four knobs for a while. This was the advice to me from one of the factory guys, and it worked. I went ahead and ordered replacement encoders ($2 each), but I never installed them because the rig has worked fine for a year or two now after twiddling the controls, and installing the encoders does not look like fun.

Re: [Elecraft] K3 Problems
Chas, If a single button held in on power up won't cure it, grab a handful. The CPU should still be attempting to strobe the panel for key presses. All you want it to do is have the lockup clear up long enough for the cpu to sense a correctable failure. If/When you get it unlocked; immediately reload all firmware; or at a minimum, the firmware that seemed to be affected. And the word corrupted is probably the most salient term here. You may have to scare the cpu worse than it already is, before it will allow a fix. You may be amazed to find that if you disconnect all devices, cables, etc and physically move the K3 so you can be sure it is not connected, in any way, to the real world; the problem may dissipate after a few hours; provided it is the equivalent of a ground loop. If not, removing the back-up battery and letting it stand for a half hour may bear favorable results. This is a computer. It fails just like any other computer.. It's stability is largely dependent on the complexity of the firmware's ability to be able to second guess every way a task can be attempted. Before you try the radical approach; Elecraft Support should be available soon, as they sun is coming up on the left coast.

Re: [Elecraft] K3 Problems
This sounds like the issue that has been occasionally seen where one of the rotary encoder push buttons fails in the on state. Another possibility is a failure of a button mux/demux circuit. In either case, a front panel board swap-out may be the next step. Hopefully, you will hear back shortly from Elecraft support on the next logical step to troubleshoot.

Re: [Elecraft] K3 Problems
Many thanks to those who responded to my plea for help with my K3. I spoke to an Elecraft engineer by the the name of Howard. Howard's advice was to remove the front panel and push it back and forth to clean the pins. I took Howard's advice and now my K3 is restored to full working order:-) The serial number of my K3 is 836 and had been in daily use for a number of years without the front panel being removed - so it is likely that there was some corrosion on the pins. Maybe others will benefit from my experience and Howard's advice. 73 from Chas - M0BIN __ 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 problems during Field Day
I was the primary op at K6MI and worked N2BJ several times. Mostly the signal was clean, but on one band it was fairly nasty, symptoms sounded like RF getting into something, think it was Saturday afternoon my time. Don't remember which band. BTW -- K6MI was QRP, CW only, with solar power and a K3 on a lovely 5,000 ft peak about 30 miles east of Monterey. Froze my *%$ off overnight, but I was working east coast and W8/W9 on 80M, and was able to run on 20 and 15 with good rates. Had a BIG tri-bander pointed east, low inverted Vees for 80 and 40 (but at 5,000 ft, low is relative). :) Lost some time due to computer and power problems, so only made about 800 Qs. My neighbor, W6GJB, had his KX3 set up about 200 ft away and was working the same bands at the same time into his own tribander using his own call. We never heard each other, and didn't work, but he did take a couple of shifts at K6MI. 73, Jim K9YC __ 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 problems during Field Day
I ran the same test using my Icom IC-7000 as the CW transmitter on 7.065. No birdies were heard on 14.060. In both test I was able to copy the 2nd harmonic with an S9 at 10 watts out but there were no birdies across the lower Charlie Whisky portion using the Icom 7K. There was an increase in the noise floor as I tuned towards the 2nd harmonic, starting at 14.120, but below that, the band was clean as a whistle. - Jack WA9FVP Sent from my TRS-80 :-) -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-problems-during-Field-Day-tp7558120p7558144.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
Re: [Elecraft] [K3] Problems abound
Shane, I believe the - - display means that the KAT3 is not being properly recognized as being installed. That fact alone may complicate the results of your other observations. You may not be able to TUNE the dummy load to 1:1 SWR - the tuning mechanism may quit tuning if the SWR is below 1.3 or 1.2 (although it usually will tune to 1.0). If you want TO ASSURE 1:1 results, you will have to bypass the KAT3 rather than TUNing intp the dummy load. If your TX Gain calibration data is not being remembered, that is a different problem, and should be addressed to k3supp...@elecraft.com.

Re: [Elecraft] [K3] Problems abound
Thank you everyone for your replies. Gary from Elecraft was awesome to chime in... He had me check a number of things, but I think the core problem was the wattmeter needed to be calibrated. Disconnect any RS232 connection and PC software control. Redo the WMTR menu calibration. When in WMTR LP or WMTR HP, turning the VFO A knob counterclockwise for smaller numbers in the LCD will result in more RF output on an external wattmeter. Turning the VFO A knob the opposite way will decrease the actual RF output. The change when turning the knob menu is small, so you may need to turn the VFO A knob quite a bit to see much change in the actual RF output on the external wattmeter. This adjustment should be done with the K3 set to the 20m band. This calibration is done while you are in the WMTR menu and you then press TUNE. In short, my wattmeter marked stuff as 6W/60W for the 5W/50W test respectively. After adjusting this setting, my ATU tunes 1:1 on all 9 bands and is pushing 100% of the power as expected!

Re: [Elecraft] k3-- problems with direct freq entry
Well, maybe that's just something I never noticed. That would explain why 7025.5 becomes 25500 (i.e., the radio assumes the mHz are 25, not 7. But it seems peculiar to me, particularly because under software control you can use decimal points. For example, if I send the radio 7025.345 from my logging program, it does take the radio to that exact frequency. 73, andy, ae6y - Original Message - From: Radio Amateur N5GE n...@n5ge.com To: elecraft@mailman.qth.net Sent: Sunday, October 25, 2009 1:05 PM Subject: Re: [Elecraft] k3-- problems with direct freq entry On Sun, 25 Oct 2009 12:32:46 -0700, Andy Faber andrewfa...@ymail.com wrote: Wayne, et al, I'm using 3.44, and experiencing odd results on direct freq entry from the keypad, all when using the decimal point, e.g.: 1) entering 21225.5 gives 21225.0.

Maybe someone will be able to help them? 73 Rys SP5EWY = Dear Sir, My callsign is 3D2KJ (SP5DRH at home), We are on a dx-pedition on Fiji with the main interest to activate 160m. We have here two rigs: K2 and K3 in use. The last night we have encountered a serious trouble with our K3 (S/N 1739) Since that time, we are observing short (a few seconds) lost of power on 160m, while CW is used. This behavior concerns ONLY 160m! That happens with a small power level being set at 6W, as we are using this rig to drive an external PA. Then, the output returns to the previous level, with a short view of a full bar on the LCD display. We tried to find if it occurs on TUNE position as well, but it looks that it happens very rarely there. The rate of this behavior seems to be unpredictable but it is sometimes a few times within a minute! On other bands everything is OK. It looks, moreover, that the rig produces sometimes some spurious signals on 160m resulting an odd behavior of our home made PA, while using a K2 instead of K3 solves the problem. This makes us unhappy since this failure might jeopardize our program. Since one of us (3d2mj - home sp5eaq) is an engineer in electronics, we have performed several tests and we are now convinced that the nature of the problem is of K3. We re-initialized the rig and nothing changed. The transceiver is loaded with the low SWR input of the PA but the same problem happens if it is loaded just with an antenna. Any local external support is impossible, we have basic tools (including soldering iron), some spare parts (but not K3 origin) and an AC/DC meter. There is a possibility that the problem began during a crash of PA during transmition without load (failure of antenna). The PA has been then repaired, but soon we found the K3 problem. It might be just a coincidence since before we had used 15W of drive. 73 de 3d2kj3d2mj == ___ Topband mailing list topb...@contesting.com http://lists.contesting.com/mailman/listinfo/topband No virus found in this incoming message.

Hi Julian, I've done that as well. I don't recall resetting the PA Temp value, that may explain the over temp warning... Did reset all the filters, so that wasn't an issue.

I removed, inspected, and reinstalled the mixer board a couple of times, no change. The noise must be being generated prior to the roofing filters because changing the filters has effect on the noise, DSP does too. There are no external antenna connections, the only connection to the K3 is the power. The PS is a Astron and it powers my K2's and K1, so it's not PS noise. If you want, I can phone you and let you listen to the noise. Did I get the lemon?

Re: [Elecraft] K3 problems
John, please do let us know, since I'll put the resolution in the K3 Wiki On 02/03/2008 20:15, John [EMAIL PROTECTED] sent: I am receiving off reflector mails in re to my problem. I know others may be interested in the out come and or final resolution, even if it's due to a short between the headsets. 50 years of hamming, and it's still a challenge and fun. At 08:54 AM 02/03/08, you wrote: Has anybody on the list seen either of these problems. This is a copy of what I sent to the service dept. received K3/10 kit on Feb 28, Ser#501. Assembly went well. I have assembled two K2's and a K1 with no problems. I used an anti static mat and wrist band throughout assembly. Problem#1 Upon power up, the K3 will not recognize the KAT3. I receive the ERR IO1 msg. I removed the KAT3, powered up and did not get the ERR IO1 msg. Reinstalled the KAT3, power up, get the ERR IO1 msg. I went through the configuration steps, no help. I tried switching between ant 12, and received a ATU not installed msg. Assume a faulty KAT3? Problem#2 This one is a booger. I have a horrible S8 to S9 plus noise (sounds like line noise), at various places throughout the 1.8 to at least 25 mhz. It shows up on the 160 thru 40 hams bands, misses 30M, shows up again on 20M and 17M, misses 15M, shows up on 12M, clean on 10 6M. Using a non metallic tuning tool, if I put pressure on the little mixer board I can cause it to go away or change.
