Hmm this is strange. Perhaps I'm doing something wrong here.
When I turn on my Blonder Tongue agile modulator in my room, the TV in the living room (which is on digital cable), looses a picture to Weak or No Signal. Cable, not OTA.
The TV lost a picture on clear QAM channel 6.1 (as for the actual frequency I have no idea, because it's a virtual channel number).
The modulator is using UHF channel 27, and is attached directly to the TV's UHF terminals. The TV's VHF terminals are attached directly to the cable line, as shown here:

If both are terminated correctly, how is the modulator screwing with the digital cable signal? (Neighbors are seemingly not affected).
