A pretty fun diversion (squirrel !), Listening to country music ... that seems to be most common in the lower frequency bands with a RTL-SDR 

Gareth turned me on to it. Linux install was pretty straight forward.  Digital packet over low band ... hmmmm.... slow but nice range

They are great powerful devices,,,,, there are a lot of strange signals out there...

I have gone through quite a number of Software packages , here are the ones I had most success with :-

  1. SDR Console                    https://www.sdr-radio.com/
  2. SDR#  (aka SDR Spy)       https://airspy.com/download/
  3. RTL1090   (for Aircraft Tracking) https://www.jetvision.de/manuals/rtl1090imu.zip

and for Android devices with a hacked usb port cable (OTG adaptor) :-

ADSB Receiver

Trunking

Best explaination I have found sofar is :-

 

 

 

RXing analogue signals is easy......

RXing Digital gets a bit tricky .... often there will be a base frequency to listen into which will divert you into multiple channels - they can be encrypted/non encrypted. To decode the digital voice to analogue voice extra programs and dirvertion of the PC's audio using virtual audio cables...

They videos above are great walkthroughs....
