I've got a bwav downlink system on my gasser that I've got a pretty serious issue with noise. The culprit seems to be the engine - as it's clear until the mount is near the heli. I'm using the stock cable to connect the camera to the transmitter, and it's about 1' or 1 1/2' too long (coiled up the remainder right near the transmitter) and it does appear to have a ferrite choke on it for noise suppression. It has lines that appear in the video horizontally, and they SEEM to vary with engine rpm's.
I'm using my Canon Powershot Pro 1 with this setup, and the video output is a 1/8" stereo style jack - should I perhaps just make my own shorter cable using shielded wire? Or maybe someone elses experience would save me some time. I've considered making the project box that holds my electronics/receiver/video transmitter connect to the mount via cat 5 cable - sharing a common for the servos ground and using one of the twisted pairs for video .. but after seeing the level of noise I'm dealing with, I'm wondering if that's a good idea. Thoughts are appreciated!
