Deaf K3 after HI RFI

[Peter-64]

Hi

I lost my RX this weekend in a contest
I got several HI RFI warnings and its ends with a low RX.
Do do hear strong station with low signals.
There is no difference in strength  if I use ant1 or ant 2. The main RX
or the sub rx.

So I guess there is an short or an interrupt in the RX circuit.
The power output is OK on all bands,
If I'm correct this means that the problems is before the bandpass
filters since the power get true them.

Any clue where to start looking at?

Thanks to all.
I found out that D25 is open.
This is a pin diode in the RX/TX switching stage

Tnx all!
