Hey h3humvee! Yes, 2-meter and 440, with two radios --
One for voice (Yaesu FT-8500 with microphone with many buttons)
and the other antenna for data (Kenwood D7 with built-in
computer interface, like for APRS position beaconing and messaging).
No, I haven't noticed any RF interference problems with the H3
although one 80-watt 2-meter amplifier I used in my Volkswagen
did mess up the car's ECU causing the check engine light to
come on while transmitting. Funny on the interference with the GMC too.
I would like to do other fun radio and mobile Internet related things
like mounting a laptop on a nice adjustable arm holder,
and installing a Wi-Fi access point that would get to the Internet
through a cell phone. Cell phones fail in remote mountain areas,
of course, and that's where the high-power Amateur Radio equipment
is really fun to use.
It's also pretty cool to see mobile satellite internet systems becoming
available (but still very expensive, like over $5000 for installation).
I heard of one guy installing one of these motorized satellite dishes
on an H2. Wonder if anyone has put one on an H3 yet...
