actually the problem did not go away. We tested it yesterday with UHF completely off, and 220 just kep making tons of noise. In fact, UHF plays fine stand alone, i had to turn 220 off when we left the sight. Any ideas? I think this is more of an issue of something getting in to the input of 220. Even stand alone without UHF even turned on, it's an issue.

Hey Jed, You are leaving out a key piece of information. Your antennas are at the same height and almost next to each other causing a mixing problem that I explained to you. The problem will not go away until the antennas are separated. You proved this by killing each transmitter separately and the problem goes away. If you look on a spectrum analyzer when both machines are keyed you will see the mix. When I talked to you on the phone about this problem I gave you the mixed frequency to look for on 220. When the machines left the factory they were both on frequency and checked with 2 different IFR's that were recently calibrated. Even if the machines were off by not even 1kc it would not cause this problem. I think since you said both are off by about the same amount you might want to look at what ever your using to measure them. Paul Maggiore V.P.
