K3 problems
Locked
 
|
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 1&2, 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. The sensitive area is the component, looks like a transistor, three leads, that looks like a pop rivet in the center. lower left on the board when looking in from the front. I can't read a component number on the board. If I put pressure on this component I can cause the noise to go away, or shift off the freq I'm listening to. 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? John k7up K3, almost, maybe K2's 2012, 2223 K1 637 Things are more like they are now then they've ever been before. _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

John:
If you sent this info to <[hidden email]>, I suspect that you will be hearing from someone very soon with help. If you didn't send it to that address, I suggest that you do. 73, Ken K3IU K3 #202 John wrote: > Has anybody on the list seen either of these problems.

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.

John, please do let us know, since I'll put the resolution in the K3 Wiki
