OnSense uses osmocom_spectrum_sense as a spectrum sensing front end, and tunes the conventional receiver using hamlib's rigctl.
OnSense can scan the entire UHF military airband in less than a second (or the VHF air band). There are 7000 channels with 25kHz spacing between 225MHz and 400Mhz. When I assessed the scanning speed it was roughly 666ms, that's over 10k channels per second which isn't too shabby. OnSense is not a great piece of software yet, but its not nonsense.
I'm hoping to improve OnSense with a QT GUI and an SQLite database.
Here's a screenshot of some onsense action:
The green stuff in the terminal itself is OnSense. It spews forth notifications so you can tell at a glance what you're listening to. I like to keep an eye on things (bugs?) by keeping grig in view and having both OnSense and grig talking to the AOR receiver via rigctld.
