I just realized there's a way around it, though, which is to connect the cable box using baseband connectors (HDMI) and run your signal with the QAM-modulated channels directly into the TV tuner. Of course, this gives you digital audio out of the cable box but, at best, ARC out of the TV for the modulated channels.
Anyway, it can be done.
In order for that to work, you would have to have a clear channel in the CATV system to modulate to (most CATV systems these days have 0 frequencies free). Otherwise your channel and the channel you just ran over top of, with both be knocked out.
Did a motel at the beginning of the year, that we added a locally generated digital channel into the CATV system. Had to use a digital notch filter on the incoming CATV signal. That filter cost me about $700 and was huge. Worked perfect thou.
