Well, when you figure that you can pass a couple of Mhz in a video channel, 
it's not too hard to pass an AM carrier frequency there. Even if you have to 
skip pulses during the H and V blanking intervals, any decent x-tal osc at the 
other end (Rangemaster unit) is not going to drift by much during those tiny 
gaps. Sounds like a pretty decent and workable way to sync a bunch of 
Rangemasters. Kudos to some creative thinking/engineering. :)
