HL2 deaf after strong RF field present

[Jiri Culak]

Good morning very unfortunate one

I happened to transmit today with a full legal limit power and suddenly realise that my Hermes lite2 latest build doesn’t receive anymore going over 20 dB in LNA causes a receiver overdrive I tested transmission and that works 100%

But I don’t like us a funny smell close to the relay and I found that the diode D1 Is short circuit. What I also found is when I transmit what’s another radio I can hear or see my signal on waterfall obviously very attenuated. 

I am so sad I have not turned the Hermes off while using another radio. No I would like to ask the group for any help in diagnosing what could be at fault and how shall I proceed. Or even if I fail if there would be anybody friendly around who would help me out looking into it for me

Tnx

Jiri
