Thanks, I thought it was. I did a factory reset on the receiver yesterday and everything else was coming in but not the Reelz MUX.
I have a cell booster and thought it may be interfering, but wasn't that. Still didn't have it with the booster unhooked. I hadn't checked for possible WiFi problems, but last night I did a discovery and found 9 different WiFi connections.
It has to be infrequency interference from somewhere because none of the channels on that transponder works and there's no signal at all.
I have a 5G cell phone and it doesn't detect a 5G service, so I'm pretty sure it's not that, at least from a cell tower. Must be another source If that's the problem.
We live 10 miles from town as the crow flies and deep down in a valley between 4 mountains, and there's no 5G on the tower we get cell service from.
Anyway, thanks for the reply.
