There are times when Google search is great, and others where it fails
me. This is one of those situations.

I'm trying to find out what people recommend for handling both APRS and
voice radios in the same vehicle. I want to have two separate rigs,
one dedicated to APRS, the other for normal voice comms. I'm concerned
about receiver overload and frying one of the rigs when the other is
transmitting at high power.

The rigs are modern (Yeasu FT-2800 for APRS and Yeasu FT-8900 for
voice). Would the intermod rejection of these two rigs protect them?
I'd rather not set up a cavity or other expensive filters.

How do others have this setup in place?

I'm running an FT-8800 for voice with a Comet CA-2x4SR on a trunk lid
mount and run APRS with a 20W brick amp into a Hustler 5/8 on a hood
lip mount. De- sense yes, damage not so far. I also have a dual band
scanner antenna on the opposite side of the trunk lid and the FT-8800
nor the 75W V-8000 before it have hurt the scanner. Other radios may
not be as tolerant of the overload.
