APRS and voice - mobile configuration
 

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?

Many do this and don't worry about it. I have not heard of anyone hurting a
receiver. I would, however, keep the antennas as far apart as possible.

One thing. The APRS transmitter should be kept as low as possible and still
get the desired results.

You can also sign up to the tapr list and query the Gurus.

I run FT 8800 on a stick roughly over the front seats, and a 30 watt maxtrac
for APRS on a stick about a foot from the back end of the roof of my Town
and Country. I get completely desensed when the maxtrac transmits, but it
hasn't hurt the Yaesu yet.

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.
