If your looking for something to set 118 to 137 and have it scan and stop on anything in between, sdr# with the correct plug in is the way to go. If you have one dongle and want to scan programmed freqs and have it scan those, sdr# with the correct plugin or DSDPlus with fmp24 scanlist works good. Both mentioned can be done with one dongle regardless of how much it covers.
Sdrtrunk will, while not a true scan, it will cover the dongles bandwidth and can stop on anything that’s programmed in. A hackrf covers close to 20 meg so I added everything of interest from 118 to 136 and it will record and play back anything it sees that’s programmed in. The same can be done with 2 Airspy r2 or 3 Airspy mini dongles. It could also be done with standard 2.4 dongles but you would need about 10 of them. Anything of interest would need to be programmed in as channels with am decoder and an alias list set up.
