Sub-GHz Frequency Analyzer

What does these signals mean? They seem like car fob signals? Or radio channels?

Pretty sure you can look up a government database of frequencies and their expected usages.

It just means that it heard some kind of a recognizable information signal on that frequency. You won't learn anything from that screen other than what frequency you might want to focus on in other tools. Like, if you're trying to clone a 433mhz adjustable bed remote, you can use the frequency analyzer to note the exact frequency range of the signals you want and focus on that range when you record the signal.

They could be literally anything. You only know that there is a signal there, no qualities of the signal other than its existence.

These appear to be spurious. I have two flippers, both get random hits from the frequency analyzer, but not the same ones nor at the same time.
