I captured some footage from Brenta Dolomites last night and noticed the following: I was giving instructions to the climbers with a 446 MHz radiotelephone while the camera running about a foot away. During the transmission there was a slight netlike interference pattern on the picture, the sound was OK (external shotgun on a side bracket). Fortunatelly this was during the "run-up", not the shot itself.
Be warned.
