Topband: Small garden DX

[John Randall]

Petr, I put the diodes before a common mode choke which I think is the right place for them to be as the choke will isolate the front end of the preamp  from the diodes. If we were talking about uWaves, then it would be a big issue and one would use a relay to provide the isolation on TX and protect the preamp, but does it really make a difference on 160m  and the nF ?
