I’m looking for a little help with a project that has been on the back burner for a while.
I have a commercial product that may (or may not) transmit data in bursts in the 433MHz band. Is they a way, or an inexpensive device that I can obtain, that can tell me the exact channel it is transmitting on? I do have a cheap receiver but the likelyhood is that I would be listening to the correct channel when it wasn’t transmitting.
Any guidance would be appreciated.
