Hello. I was wondering if connecting oscilloscope to the antenna of the RF transmitter would work? I'm just trying to see if it outputs any signal at all, because I've been working on receiver/transmitter for 2 days straight, and my receiver doesn't receive anything.

My only concern is that the transmitter works at 800+MHz, and my osciloscope - 100MHz, but I don't need to see the whole signal, I just want to know if at least something is happening

Most scopes cannot display the RF envelope. Many times however, you can see a good part of the modulation if it's am AM circuit.

If it's an FM transmitter... Hmmm, I never tried that.
