Hi
you beat me to it, I would suggest a duplexer problem as -55dB

the fact that you are running too much tx pwr, have you tried dropping
it down.

Hi Jeff
yes I know -55db is I think around 399 microvolts
No, you're still missing it. He said -55 dBm (m = milliwatts), not -55 dB.
which will flatten any receiver
-55 dBm at 1 MHz offset isn't going to bother any half-decent receiver. A
decent receiver would have 100 dB of adjacent
