New 2m shack radio

With the old 2m radio installed in the car, it was time to install the new 2m radio in the shack to replace the old one. We picked up a Yaesu FT-2980 a couple months ago and this weekend’s project was to get it up and running.

A 2m ground plane antenna was installed in the attic a few weeks ago, but I ended up having to reposition it to make it easier to run the coax into the shack. Once that was done, I was able to feed 50 feet of RG-213 coax through the conduit running into the shack with about 10 feet left over which got coiled up next to the antenna.

After a bit of running up and down between the attic and shack, I got the antenna trimmed enough to get ~1.1 SWR across the band.

The weekly ARES net gave me a chance to test out how everything sounded and see how well I was able to get into the nearest repeater. At first, it didn’t seem like I was being heard on the repeater, although I could hear everything going on. After looking up the repeater details, I discovered that I had the wrong CTCSS tone set. Once that was fixed, I had no problem being heard on the repeater.

On a good note, the radiant barrier on the roof sheathing seems to have absolutely no effect on the radio’s ability to pick up RF (in the 2m band at least). I wasn’t expecting the radiant barrier to have any effect, but I occasionally see people in forums say they’re bad for radio. I suppose that would depend on the type of radiant barrier that’s installed. The barrier on my house is just a thin layer of shiny foil type material glued to the back of the roof sheathing and as far as I can tell, doesn’t have any effect on the radio’s ability to hear the local repeaters.
