We have problems getting the radio to work at a height of less than 10' above the roof (antenna ht). I'm about 30-40' below the antenna with these cards. The antennas are highly directional dishes. Might be a problem, but wouldn't explain why when I turned both ends off I still have problems with the aviators. I kinda think it is "enemy action" given the random nature of it.
