70cm radio in the shack

Got a 70 cm mobile radio set up in the shack yesterday. It was a radio I picked up at the Charleston Hamfest a few years ago but had been sitting in the closet waiting for me to get to. After getting the 2m radios set up in the car and the shack, I decided it was time to turn my attention to the 70 cm radio.

The radio is a Yaesu FTM-3207D. It’s a nice, compact little radio, in pretty good shape, and works great. Programming the memory slots is pretty simple and pretty much the same procedure across the other Yaesu radios that I have, so getting the local 70 cm repeaters stored went pretty quickly (there aren’t a whole lot of them in the area).

The radio is currently connected to a 2m/70cm dual band mag mount that I used to have on the car. Got the mag mount set up on a shelf sitting on a side panel from an old computer case as a ground plane.

The microphone is still functional, but looks like it’s seen better days. The cable covering has become brittle and broken away. Fortunately, replacement cables are available and it’s easy enough to replace.

I managed to check into the local ARES net last night using a repeater about 30 miles away with the radio set to high power (55W). Don’t know how I sounded, but it must have been good enough for the net controller to pick me up.

I’ve got a little handheld Arrow 70 cm Yagi antenna, so maybe I’ll work on getting this radio outside to see if I can eavesdrop on some FM satellites, or see what kind of UHF FM simplex I can do.

The antenna. If you look closely, you can see some internal structure now, compared to the fluoro image from earlier.

Put my VX-8DR under a fluoro unit I was testing today. Fluoro generally doesn’t provide the greatest resolution images, but enough to see what the innards of my radio are like. Will get a regular radiograph later.

This is the antenna. Not a whole lot going on aside from a lot of metal.
