Back to shielding wires using audio stereo shielded wire and using the shielding as ground..

Im guessing thats not apropiate for a PPM encoder?

I use a PPM encoder to encode the Rx chanels into one PPM thread... and to plug all 7 chanels i use 3 servo leads.. one in the chanel 1 + 5V + ground and the other 2 put perpendicular in the other 6 signal pins..
If i change those 3 wires im guessing 2 chanels (4 and 7 , tought 7 is not used) would be throught the shielding so they would pick interference?

If i change those 3 servo leads to much shorter ones (now they are like 15cms so i have to wrap them arround the PPM encoder... i could shorten them down to 2 or 3 cms ) would that decrease RF picking?

Also i asked before but got no answer...
is it recomdended to shield the Video Tx wire? (from OSD to VTX)
