Default Los Angeles County Radios

Yep;
When I saw the locations of the sites and did the simple math it was obvious
to me the engineers of that system did not have a clue as to intersymbol
interference on a simulcast system. They had no business putting that system
in. And because the County used a system integrator as opposed to hiring
GE-Ericsson up front, GE-Ericsson had no contractual responsibility. They
got their money and tough luck to everyone else.
The County was anxious to get the system integrator off the job so that
GE/Ericsson (now M/A-COM) would fix the system. County accepted a couple
million dollar settlement from the integrator, they left town and guess
what? Now Ericsson wanted to replace a big portion control subsystem of the
just installed system at megabucks without providing any solution to the
simulcast coverage issues.

All that being said, the system should work ok in many areas, it did 8 years
ago anyway! So I wonder about your scanner programming. You might try
programming an EDACS system of another smaller locality into the scanner to
make sure it and your methods are working. Sometimes fleet coding can get
tricky. I do wonder if over the last few years the County sprung for the
controller upgrade that does scramble the control channel data (to prevent
eavesdropping) but I doubt it.
