These radios are out of depot service, so Motorola probably won't touch them.
Usually you just get a blank 8-pin RJ-45 and short the hangup pin to ground so that PL will decode correctly (I don't remember the exact pin numbers at the moment - sorry). It could be just local mic audio being injected since your likely keying the TX using the accessory connector. If your convinced that its an internal problem, I'd try seperating the logic and RF boards to reset the interconnection between them (could just be oxidation or something acting like a pickup).
