[Motorola] Multiple mobile radios on one band (Was: Re: Installation Tips

[Glen Zook]

I have never run into any damage to a receiver from
other transmitters in the same vehicle.  There is
definitely "de-sense", not only on those on the same
band, but often on the other bands as well, when a
transmitter is activated.

Just how to tell which radio is talking requires skill
in knowing what traffic is normally on which
frequency.

Making each microphone a different color combination
does help with keeping them "straight" when
transmitting.

Now, the particular Fire Chief with 9 radios in his
squad car was known by his friends as "Code 3",
meaning that he went virtually everywhere running
"Code 3".  He was accused quite often of running "Code
3" to his coffee break!  This, of course, wasn't
really the case, but it made for lively conversation.

Frankly, with today's technology, having more than a
very few radios in a vehicle is not necessary.  But,
there are always those who do use the older equipment
(either out of necessity or out of nostalgia) and who
run a lot of radios in their mobile installation.

Myself, having come from the Twin-V still being in
common use to the modern solid-state equipment,
definitely prefer the modern gear!  By the way, back
in high school (1959), my first 2 meter FM rig was a
Motorola FMTU-30D transmitter and an FMRU-16V receiver
(twin casket sets).  The 5V and 41V were too new to be
available for most amateur use.

Did those of you with multiple rigs have any problems
with interactions?  I expect transmitting will desense
all other radios in the same band, but is there any
possibility of front end damage?
