When I put it on my test bench, it could barely hear a 60% modulated 10uV
signal...........not good.


Seems to me I have a similar problem with my 525.
Lost about 20-30dB on sensitivity on all freqs (no VHF/UHF board
installed) :-(

I had a look on the scematics and thoutgt about the input stage amp FET....?
Sadly I have no measuring equipment available other than a good digital
multimeter....
