I work for a radio communication installation and repair business, and I’m wondering if the Flipper can scan UHF frequencies from radios I’m working on, to get a baseline to work with my spectrum analyzer or be able to read portables or mobiles in the field.
Yes, it can do that. The frequency analyzer works only on a very short range (less than 1m) though.
There is a Spectrum analyzer app for Flipper on Github in one of firmwares forks. Is that what you are looking for?
Possibly, I will have to take a look at it
