Default Re: Common Pye PF1 RX deafness problem

Well, I managed to improve the sensitivity on one of the receiver's to normal levels by replacing the first RF amplifier, TR1. I had no success with the 2nd deaf one replacing this same Transistor and a visual didn't find any problems, but I fitted a BNC socket with 1/4 wave stubby in place of the plate antenna which increased sensitivity a fair bit.

I'm very keen on these PF1s, so now that they're sorted - please feel free to post to your hearts content on this thread. It all makes for interesting and good reading.

A big thank you to all that have offered help by the way.
