[1000mp] MP Receive Problem

Tue, 28 May 2002 05:19:55 -0000

That is FB when the amp relay is the issue, which it appears to have been

degradation at the TX/RX transition, the T/R relay does not appear to be the
problem, although one or more of the sealed DIP relays used on the circuit
boards may be the culprit.
