Things you can do with a Software Defined Radio (2024)

I got a walkie talkie set as a Christmas present when I was 8. Which was kind of an evil thing to do given I had no siblings or friends to play with. One day I turned one set on and listened for a while and I thought I heard someone talking behind all the static noise. So I said something and was shocked to hear the voice talking back to me. Fast forward a few decades, next week is my wedding and that voice on the other side of the radio is my best man.

my family had a little portable TV (GE 7-7150B, link below) that we'd usually only use down in the basement during severe weather.

one day I learned that you could tune in all sorts of non-TV frequencies. In particular, you could tune into any phone calls my neighbors were making on their wireless phones.

i loved that little tv and used it up until the conversion to digital OTA tranmissions.
