clear. It makes me wonder if Sam is actually coming in via GROUNDWAVE at
my location (Sacramento, California) which means it MIGHT be coming from
one of the 2 or 3 "secret" military transmitters within 20 miles of me.

Well, I would take a wild guess and say he is in or near "Yosemite" National
Park?
Perhaps it is a remote, solar powered transmitter setup inside a cooler on
one of the high peaks. [shrug]
