Batboard

On one of the 3k's over here, on a channel that is set for a TPL tone on RX, there is a "clicking" or "popping" noise in the audio, that happens at the exact same time that the red LED RX indicator blinks on top. Doesn't directly affect audibility of the recieved audio, but it can get annoying. This does not happen when it is on a channel set for DPL on RX.

Radio is DSP8, m3, UHF R split.


Any ideas?
