Thanks for the technical insight! This kind of thing fascinates me, but I've never really studied it in depth. I understand the terms you used (ATSC, DVS-B, etc.) but didn't know about effective radiated power. Thanks for that and welcome to Amtrak Unlimited!Ka and Ku satellite broadcasts using DVB-S protocol are an entirely different beast than a 6 MHz wide ATSC broadcast signal.If it is known that it does not work well in moving cars or RV's how does things like Direct TV work in planes? :huh: I assume Direct TV broadcast digitally, and I have yet to see an RV moving as fast as a 757!
