Just Another Sucker Thanks
The Info you gave us was what we had, but instead of looking for different receivers, we simply tried again. Boom, lovely test pattern, maybe it wasn't there this morning, or we screwed up, but THANK YOU.
Nasa has a digital CBand feed or Live Interview Media Outlet (LIMO) on AMC 6. They say there is a test pattern, but we can't find it? Reciever finds 4 channels, but 4 is a black screen, first 3 work well. Just checking with you all, thought maybe one of you would have an answer.
If all you have is the 722k, sign up for the DVR advantage. It costs 10 bucks, but includes the locals, dvr fee, and the extra tuner on the primary receiver. No phone needed!!!
It won't work. DP switches are not compatible with DPP feeds. Somtimes we install a DPP 4*4, and then cascade DP3*4 switches to save money. The 1st switch Must be DPP>
2nd feed at ground block is a spare
2nd diplexer inserts at ground block, tv, rf side is new run to 2nd tv
diplexer must be rated to 2250 MHZ
From Your drawing the cable splitters have Nothing to do with the 722 feed or the backfeed. Goodluck
