What You Will Learn in This Week’s Podcast:

  • Today, Greg does not have a hardware scanner at all, but only a SDR.
  • His area has simulcast problems that the SDR solves.
  • Greg currently uses about 8 RTL-SDR dongles, including 3 on a Raspberry Pi, some on another Raspberry Pi, an old laptop, and more.
  • Greg also uses Trunk Recorder, which is one of the most difficult things he’s ever configured, but he loves that it monitors every voice channel at the same time.
  • RDIO Scanner is a web interface that takes the feeds from the virtual recorders Greg has going and cues up calls on every voice channel so you don’t miss anything.
  • Because it’s a web interface, he can bring it up on his phone or tablet from anywhere.
  • Greg thinks the next major SDR development will eliminate the need for any fully hardware based radios entirely.
  • An SDR can do things that not a single hardware-based scanner out there is capable of.
  • Greg has used his SDR to tune into his utilities smart meters for his water and gas to track his usage.
  • One of Greg’s favorite things about SDR is that you can see the signals and whether they’re strong or not, whether they’re digital or analog, etc.
  • The ability to visualize the signal lets you find a lot more new stuff to listen to.
  • The flexibility of an SDR and ability to do so many things at once with it means you get the equivalent of several premium subscriptions to other services.
