Q. Why is my transmitter still not working with my receiver after I have dialed my Spectra to the correct channel?
A. Make sure that you have the correct 1st and 2nd digit for the channel dialed into the Spectra correctly. Also, in the case of the Eclipse and Prism 7X, make sure that the transmitter is on the correct shift (negative or positive) and the correct modulation (PPM or PCM).
