I need some help if possible. After years of service my PCR has again gone=
=20
deaf. The first time was due to a corrupted eeprom. This time my eeprom=20
backup compare was the same as the originals. So, yesterday I spent a few=20
hours with the ex2099 program and my service monitor. I was able to improve=
=20
it....BUT, it is still deaf. Below 7Mhz it won't hear ANYTHING, above 7Mhz=
=20
the best that it ever hears is about 2uV.
Has anybody ever encountered this OR have a good schematic so I can=20
diagnose it?

If not the next step is to send it home to mama....$$$$$

Thanks in advance,
