im powering the tx from my balance lead..

they are normally fittrd as close to the video TX as possible to make the best filtering
but in saying that check first before you fit it as you may not need to filter the line as you are using the same powering technique that i use and i have a good clear video with out filter (its still sitting in its bag)

all was fine till i wired in the osd now i get the dreaded lines.ive put the l-c filter between osd and vtx.
improved it slightly but there still there..

oh ok bugger they can only filter so much and if strong not filter it all
i have the cyclops osd on the plane and not had any probs and use minim osd on the quad  and have been lucky that have no interference from either

did a goggle search on it,seems others are getting em too.
ah well its not too bad at mo.
l-c filters are easy to find in electrical equipment,ill add some more if i find some..

I was wondering if you have found any circuit diagrams (with values) for a filter?

just google l-c filter click images,youll find loads..
