· Operates on 900 MHz frequency ^^^^^^^ That is not an FM transmitter.
The unit shown requires a transmitter AND a 900MHz receiver.
It is if it¹s frequency modulated. Just because it¹s not on the FM broadcast band does not mean it¹s not FM.
Wrong. It is a transmiter and a separate 900 MHz receiver, which contains an FM transmitter, which transmits to every FM receiver within maybe 50 feet. The receiver/FM transmitter end also has RCA outputs for a line level input to a receiver or amp.
Your hand is acting like an antenna. try attaching a length of wire to it in various ways. (wrap around the antenna, case, or whatever)
