Pardon me for being late to the party here...
I often have this dream of a closet full of digital convertors on the few useful channels (This!, Movies!, Retro, Antenna TV, etc.) pumping into Blonder Tongue aglie modulators. Then I spin through the dial with my SC 600 and the world is good again.
But I probably won't get to that project until the rest of the broadcast spectrum is sold off and the whole damn thing is a moot point. Perhaps I'm asking a technical question that is over my head, but it seems that the issue of digital converters "overloading" the signal or introducing too much noise is identified.
Could anything be hung off the back of a convertor to clean up the signal and/or reduce the strength? Even if that requires and actual circuit and power supply... Can anything be "tweaked" amongst the IF/Video/sound coils of our sets that would improve the situation?
I'm trying to impress my friends with an episode of original Star Trek when the commercials for trans-vaginal mesh lawsuits come on and the buzzing around the 1-800-VAGI-SUIT lettering blasts our ears. Or Tom Kruise tries to sell me a Hover-round™ ScooterChair, and the video overloads and gets dark. Bad Times
Notice how the same menu screen goes from gray/black to all black, and the background content doesn't appear much different? At least to me.
