[NLRS] First tests with DVB-T dongle, ATV angle

[Mike KBØozn]

Hi all,
Doug is correct, ATV is focusing primarly on DVB-S for cost reasons 
among others.
Gary, K0GX built a transmitter using boards from BATC at a cost of about 
$500, and Bill, N0MNB, had a FTA receiver.  It worked well from what 
they've told me.

ATSC would be nice of course principally because we all have a receiver 
for that.
