Randy, When looking at the front of the Receiver interconnect board, the J903 contacts for the Audio & Squelch Board are numbered left to right, 1 through 18. Diode CR957 is directly in line with contact #11. If that diode is present, you may have a Base Station rather than a repeater, in which case you may have some serious RFI issues. Check the Model Number stamped on the circuit board; it should be a TLN5646A or later. If your board is a TLN5648A or later, it does not have the filtering needed for duplex operation.

Is it one of these four? The receiver is muting on tx. Yahoo!
