WISC CBS Channel3000 reception problems
There have been several posts about this in the past but I thought I'd try again perhaps with more specifics.
I have a large, aluminum antenna and am around 8-10 miles from the broadcast antenna. All local channels come in with strong signals.
For channel 3 (WISC / CBS / Channel3000), my digital tuner usually scans and locks onto channel 25 (UHF) which typically shows a high signal quality very consistently.
However while using channel 25, if I watch the tuner monitor (using an HDHomeRun device) for a while, once every few minutes the signal entirely drops out for about 1s. The result is corrupted video.
If I'm lucky sometimes I can rescan and the tuner will lock onto channel 11 (VHF) which is rock solid and does not have the odd signal drop outs.
Unfortunately my tuner (and most) do not have the ability to customize which channel to actually use for virtual channel 3.1.
Is there something wrong with the channel 25 transmission? Has anyone else seen this? Or do I have some interference gremlin near me?
