Thanks Curt: That is a possibility, but one would think that there
would be at least one or two hits in a 2 week period. My deviation was
normal (3.0khz).
Oh well. probably won't be down there for another couple of years...

I was recently in the Murietta/Temecula areas and was not able to get

I did talk to one of the operators down there and he says nothing is
different from the other parts of the country, but there must be
something different. As soon as I left the area to return,
everything started tracking again. Nothing was done to my equipment.
Perhaps they're running with no FM pre-emphasis there, as in
D700/D710 digi's, while you're using the MIC/SPKR connections to an
FM rig (the most common setup for APRS on 1200 baud) and therefore
using pre-emphasis? Pre-emphasis differences, too much twist, or
too much/little deviation are about all I can think of.
If the stations you saw down there were all running D7/D700/D710's,
the pre-emphasis idea might fit.
