Excuse my ignorance, but how would I know if my modulator is ATSC? It says that the modulated channel can be set to 14-69 for UHF, 70-94, 100-125 CATV - would it need to be set above 69?
Is it possible to take a live camera feed that is going through a modulator (whatever channel) and put it to the OTA and that camera become part of the channel lineup?
