[Kenwood] 950SDX Repair: Static in RX]

[bbbnntt]

Mike,

Sounds similar, but no static when I disconnect the antenna (only white 
noise).
There is some light static when I switch to the dummy load, but 
different from the 2 layers of static I get when it is connected to the 
antennas
Nothing on the S-meter
