What are the sources and cures for radio static?
I spent $10,000 on a Garmin 430 and have big time squelch
problems which sometimes make the radios unusable.
Thanks

John,
If the squelch "breaks" always occur on specific 430 set frequencies, then,
it is a problem in the 430. I had to send my 430 back to Garmin and they
fixed it. My 430 had a problem with 132.200.
If the squelch break is random then, who ever installed the 430 should go
through the software squelch adjustment procedures. If that does not fix
things then, you have an RF noise problem. It is know that some earlier
models of KX-155's comms. radiate quite a bit stray RF and that will set off
the more sensitive Garmin 430 receiver. Other comm's may do the same.

Does anyone know how to adjust the auto-squelch on the
Garmin 430? I imagine this needs a Service Login and
password?

John,
The adjustment of the 3 bands of 430 squelch is fairly complicated.
It takes the proper service manual and a very accurate signal generator with
very good low level attenuation capability.

John,
If you don't have it the 430 manual, you can see
