Re: [Elecraft] Frozen K2
Hi Did you try a master reset. Hold down buttons 3,4 and 5 while powering on. If this fixes the problem you will need to run CAL PLL and reset all of your filters as well as any other settings you may have made. This resets everything to factory defaults. This may clear the lock up.

Suddenly the poor thing appears to be dead. When powered on the display first shows ELECRAFT then 7100.00 and a constant sound hears. It does not respond to any buttons or knobs, except for the power knob. I believe that a bad extension cord is to blame. But what can I do get live in my dear friend again? Anyone who knows?

RE: [Elecraft] Frozen K2
Is your key line shorted? That sounds a lot like a K2 with the CW key closed when it's turned on. The tone is the sidetone, but it won't initialize properly with the key closed, leading to a lot of issues. I haven't managed to do it, but shorting the PTT line on the mic might do much the same, but I suspect the tone is the sidetone which you won't hear in SSB mode. If you don't have a key plugged in, check to see if something is shorting the key circuit at the jack - or perhaps if you have been doing anything at all inside the K2, look there! Most problems come from the last place touched, no matter how improbable it seems!

He has built two K2s and his theory is that the rig is stuck in transmit and that the audio is the side tone. That explains why it only responds to the power knob. So what, if any, can be done about this? Best 73s Rolf SM0YQC Stockholm, Sweden ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Frozen K2
DOH! Of course...If BOTH the dit and dah lines are shorted to ground and you have auto-sense on...that would cause a continuous carrier instead of dits or dahs. Didn't think about that at first...sorry. Tom K2TA - Original Message - From: Tom Althoff [EMAIL PROTECTED] To: Elecraft@mailman.qth.net Sent: Friday, December 30, 2005 8:16 PM Subject: Re: [Elecraft] Frozen K2 Rolf...how is your K2 normally configured? Do you keep the key input set to normal/reverse keyer paddle input or Handkey? If you normally run a straight key, bug or external keyer then yes a possible short in the keying line would explain your symptoms. But if you normally use the internal keyer and the keying line was shorted you should be hearing either dits or dahs constantly. A stuck keyswitch on power up would lock up all buttons but not generate a tone. Sorry I can't be more helpful.
