Sorry, I got the other msg first. In that case mic cord shielding & rf feedback are possibilities. Keying the transmitter without mic attached should resolve that question quickly. You should be able to easily determine the keying line at the mic cord Jack and apply a temporary ground while checking the rf waveform. Let us know how that goes.
