    recently from the local state surplus i bought some SBI wireless transmitters and cameras.
    one is just a video audio transmitter with a vbs in connecter and a 1/16th audio in and what i think is a 1/16th power in
    the other is a fully assembled "wire" with micro camera and mic this one transmits on 2473.1875MHz but the other one does not specify the frequency it transmits on.
    My question is how can i find out what signal it is sending on what frequency
    and how to build a receiver for them.
