K3 #2257 woke up deaf this morning ...

Hi Folks,

I powered up my trust K3 #2257 this morning and found it deaf. The RF and
IF stages appear to be working just fine. I have 20M FT8 showing lots of
signals on my P3, but no audio.

WSJT-X shows no audio from LINE OUT either.

I'm on the right antenna and haven't fiddled with parameters for months, so
I am wondering if there is anything I might try/check before taking it over
to Watsonville for repairs.

Thanks!

Check all connectors. I've found that connectors that just "sit" and
are never moved will oxidize and prevent signal flow. They rely on a
mechanical connection only. Just unplug and re-plug 2 or three times
for each one.

Thanks, Bob. I powered it off and on a couple of times and it came roaring back to life.

In many ways this behavior Is just as disturbing.

When I have a couple of hours I’ll put it on the bench and exercise (gently) the internal connectors, etc.

Thanks for your suggestions!!

Also check your filter, NB and NR settings, sometimes they go wonky.

Re: K3 #2257 woke up deaf this morning ...

When unplugging and plugging in coax connectors to improve the connection a spray of DeOxit on each end would be a good idea. Works on all kinds of switches and connectors. I wouldn’t hook up my four trailers to my car without it and those connectors are heavily abused. Less so for my coax connectors but a good idea anyway.
