T100 RF susceptability
Hi All!
Back again with more questions; '96 T100.
I'm an amateur radio operator. In conjunction with some planned upgrades to the audio on my truck (see previous thread), I hope to install a dual-band transceiver for 2M (144MHz), and 70CM (440MHz). The Icom radio I have outputs about 50 Watts on either band, and will be driving a simple 1/4 wave mag-mount antenna on the roof, at least to start off with.
I have the radio in my old Ford F250 at the moment. The 2M band works fine, but transmitting anywhere in the 70CM segment stalls the engine (no ignition) until you let go of the PTT button :-(
Anybody have any experience with putting ham radio gear into one of these trucks, or really, any Toyota of similar vintage? Any RF issues? I'd really appreciate hearing from you!
TIA!
ByeBye! S.

Hi Guys!
CB is _usually_ less of a problem than ham gear; lower frequency (27MHz), for one thing, and lower power (< 5 watts) for another. Never the less, encouraging news.
In my case the radio will be living in the dash with the stereo; top slot vs. bottom yet to be determined.
FWIW, a couple things you can do that will generally eliminate or at least greatly reduce alternator wine:
Run 12v to the radio/stereo _directly_ from the battery using heavy wire; 12ga or better.
Pick up a solid ground connection as close as possible to the unit, and run wire as above.
Use a hi-quality in-line noise filter RIGHT AT the electronics. The best filters are the ones that have metal cases that can be grounded. If you find one of these, ground the case as in #2 above.
Ummmm, that's three, huh? Forgive it :-)

I installed an Alinco VHF/UHF ham radio in my 01 4Runner, and have no problems transmitting on any 2 m or 70 cm frequencies. I wired the +ve in mine to my auxiliary fuse block on the firewall and the ground to a convenient bolt near the radio. I have mine installed where the ashtray used to be, with the coax running across above the steering column and out through the firewall to a hood channel NMO mount antenna.
