Hi Muzza

I don't have it muting exactly. Mine is more a glitch (almost a skip if you will) when the RDS-AF stuff tries the other frequencies to see if they are stronger.

I'm guessing this is on 107.7?

Unfortunately though you can't turn AF off (due to a bug which appeared in 2.0final) which makes JJJ almost unlistenable for me because of the glitches.

The way I understand it though the RDS-AF feature of testing other frequencies for signal strength shouldn't intrude and shouldn't be audible. In that case I believe it's not doing this correctly either.
