Thanks Thompson. Since all the work was done in tweaking palmod to resolve the initial problems there has been seldom any issues with sound loss, and try as I might I cannot re-create them with my antenna setup. The only lead I can tell you is that every now and then a grotty audi carrier gets detected wrong and this causes loss of sound.

Because it is a check only done once when the channel is changed (that I know of) if it don't detect a clean audio carrier then this problem can result. Is there a way for palmod to test the sound carrier at very regular intervals in an effort to combat this problem without the micronas introducing any annoying glitches into the sound?

Cheers
