Revisiting SDR

Six years ago, I did some experimenting with an RTL-2132U USB dongle as a software defined radio on a Mac. Being stuck at home due to the coronavirus quarantine, I decided to dig it out and try setting it up.

After banging my head on the wall for a few hours trying to get various software packages to work, I downloaded CubicSDR onto my MacBook Pro running Catalina, and it pretty much just worked.

Here's a screenshot with the thing tuned to 102.9 WMGK:

I'm able to receive 92.5, 94.1, and 102.9 easily. 93.3 WMMR comes in poorly, but I'm in a little bit of a hole and my antenna is far from optimal. I'm using the little thing that came with the dongle.

I think I have an adapter cable that will allow me to connect the dongle to an SO-239 connector, which will be good because then I can use a 2M/70cm mag mount antenna and monitor local repeaters.
