Something just happened...

Good morning

All of a sudden my K3 (2066) seems to be muted in CW on receive, and I lost the sidetone while TXing.
In all other modes I have audio as before.
What to look for?

Re: Something just happened...

Good morning to you too, Ben.

In CW mode Hold the CMP PWR knob, then release it and turn it clockwise.

SM6CKU earlier this morning

In reply to this post by SM6CKU-2

I found the problem. For some reason the pitch of the sidetone was zero and was adjusted and sidetone OK. But how can that "mute" the receiver in CW mode?
Now everything is normal but these small things makes me nervous.....

Re: SM6CKU earlier this morning

Ben,

That would explain it. A pitch of zero would put the audio in the sub audible range and probably put it below the bandpass of the audio amplifiers and filters resulting in muffled or no audio in CW. If you set your IF bandwidth high enough, you would have been able to hear stations that were quite far away in frequency but not the ones you were tuned to. I'm curious as to how the pitch got to zero, I thought the K3 had a lower limit around 400 Hz for the CW pitch. Anyway glad you found the problem.

Re: SM6CKU earlier this morning

The CW pitch has a bottom limit of 300 Hz. He probably had the MON
setting at ZERO, which would have the same effect as described.

Re: SM6CKU earlier this morning

Hello guys,

Well, it just happened when I started to call CQ and I have no idea why. The
MON was indeed also set to zero, which I discovered first. Strange things
seem to happen with this radio (Windows-like), but I still enjoy it :-)

Do you power it off from the front panel? Not windows, but the firmware
of this radio wants to be properly shut down, don't just yank the power
plug :-)
