[Kenwood] 950SDX Repair: Static in RX]

[bbbnntt]

Clif

I just did a re-rest. I have an IC-PW1 amp. I connected the 950SDX to it 
as the #2 radio and switched back and forth between the two rigs. Same 
results with the static on the Kenwood, with all 3 antennas connected to 
the PW1. In addition I was able to see the differrene in the receive 
between the 2 radios. In most instances the compared to the ICOM the 
950's rx is almost unintelligible as the static takes over the received 
signal.
