Hi Barry,
Heard you once in the contest - you were doing S&P and nailed someone
either just after or just before I did. Your signal sounded FB. I'm
curious, are you running with a low sidetone? I use the default 700 Hz
sidetone and the PBT control is almost always at 12:00 position. If you
were running a low frequency sidetone, say 400 Hz, then the 11:00
position is correct. If not, then it sounds like the alignment is not
right.
