Thank-you as always for the info Rabbit. I had no idea that broadcasters were switching channels again. This time it is part of the 2016-2017 FCC incentive auction (per Wikipedia). I called the junior station engineer up on the mountain-top and he said there will be some new transmitter equipment installed as part of the switch. He didn't know if it would be more powerful or less powerful, but I'm going to call the senior engineer Monday night who junior told me will surely know. He's been up there since Elvis died in 1977.
Hopefully, power levels will go up and coverage will increase...
All other things being equal (i.e. transmitter power), does a move down the band (i.e. WFFF going from Ch43 to Ch16) bode well for deep-fringe reception areas like my house?
