I flew at least 30 times this past weekend with 2 different planes both on the same channel with absolutely no problems. I know Jack did have a problem but had solid radio link the rest of the weekend. I don't think there was deliberate tampering but I do believe that there may have been a few problems with frequency control. There were also a mutitude of problems with people getting the pin and keeping it for a long period of time working on their airplanes in the pits.
