A bit of yes, a bit of no. There was a receiver pointing to LA and the
repeater pointing towards China Lake, but there was a power source, an
independent diesel generator. I think a line was eventually run up the
hill.

I believe this was the first installed repeater anywhere, the legality was
never brought up (at least until the power line was run). I had seen some
TV at China Lake before the repeater, talk about 'snow'
