Walk around the yard or neighborhood looking for noise sources? Significantly higher-tech and more accurate than using an old battery-powered AM radio.

Don't want one just don't know what purpose they would serve.

Well good. I wasn't trying to sell you one.

That's not an SDR receiver, its just a spectrum analyzer.

You can put an app on your phone for free and have the same thing. In android, its 'pocket txrx'. Nowadays there's always 'an app for that'
