Does your K3 have gold pins on the front panel connector? The old
tinned pins were apt to cause a lot of weird/intermittent problems.
Glad you were able to fix the D25 issue.

The K3 that went deaf and I replaced D25 in - has had another issue
that I have not understood - and it is only annoying when it happens.
Sometimes I will turn it on and it all seems fine but it hears zero
signals - it is not that it is deaf it is more like it is not
working. It does have receiver hiss that makes you think it is fine
and it seems to transmit (although I have not tried to listen to it to
confirm) but it just does not work at a receiver.
I should try the TX next time.
Power cycling the radio once or twice usually makes it work right away
and it is fine. It does not fail like this at every power on.
This radio is being used as a remote radio - and I leave it on almost
all the time - that is one reason this is not been more of an issue
and often I forget it does this - until I power it on. Like last
night after replacing D25 - and the radio seemed deaf - but even more
deaf than before as it coudl not even fainly here the signal
generator. Then I remembered the power on issue and I turned it off
and back on and it came to life.
It is an older K3 that has been mostly upgraded to a K3S.
Single receiver.
2m module.
Newer pre amp.
USB interface.
RX ant ports.
Anyone recall seeing this symptom before?
Thanks
