I bought one from an "ex-friend" and it has no RX or TX.  Everything else seems to work OK;  the microprocessor, tuning, displays, meter, audio, etc.  Could be a PA board problem.  I have 2 mikes (desk & hand), power cable and manuals ( and on CD or DVD).

Make me an offer(?)...  I'm in St. Louis and will ship UPS Ground or local pickup.
