Right now, I have a Kenwood TM-D710A radio in my car (VE6SRT-9, see sig), hooked up (use the term loosely, for the wires are just twisted together and wrapped in electrical tape) to a Garmin GPS18x. The radio is also connected to the car's electrical system thru a cig lighter adapter, so I have 2 devices via cig lighter adapters I don't really want to do that way (the radio and the GPS). I already have a Garmin nuvi, an HP1 scanner, and another GPS18 for the HP1, all plugged in too.
Crawling its way to me at a glacial rate from HRO New Hampshire (shipped Jan 16, still in Jamaica NY as of tonight) is a GPS-710 from Green Light Labs, which will solve the issue of the cobbled-together GPS18x - and at the same time I'll be connecting the radio to the battery with an APO3 automatic-power-off relay inline, so all that will be removed from the cig lighter plug-in.
I have an Argent T2-301 as well for playing around with. It runs as either VE6SRT-12 or VE6RWM-1 depending on what I'm doing with it. Probably going to end up being VE6SRT-8 ultimately, plugged into my other vehicle as a tracker with an Argent GPS or the extra GPS18x.
Oh, and I guess VE6SRT is also up, using AGWTracker on my Win7 PC at home, currently connected only to the Internet (no RF).
I was going to use the T2-301 as a digipeater (hence the RWM-1 callsign) at my fire station, because the digis nearest me have spotty coverage in that area and points south (towards my home), but even hooked up to the spare antenna I have at the station, it doesn't help out. I think I need to repurpose one of my old VHF Maxtracs and hoof it up our radio tower with an antenna. The half-broken control panel I just replaced on my D710 (volume knobs broken off) would cover the necessary work as a digi TNC when hooked up to the Maxtrac, am I right?
