It remaps to 2-1 on the HDV 420 here it doesn't "do" program guides, I have remapping/program guides turned off on the DTC-100, and I get 50-2 on it.

Maybe it's just me,but I've noticed all of the UHF channels seem to be *snowier* than they were a couple years ago.Do you think a strong DT channel,or a combination of strong ones, could bleed snow further than one adjacent channel?
Let me know when you want to get started on that 300ft tower.I'll be right over!
It's amazing how complicated a subject "noise" can be!
My guess is(and it's just a guess), Theoritically and generally speaking, unless a DTV transmitting facility is "on the fritz" and is putting out "stuff" where it isn't supposed to be I wouldn't think so, at least in a "perfect" world with such things as tuners that are "perfectly" selective, where extremely strong signals didn't overload tuners and preamps, and preamps didn't add a little noise in the mix to begin with.
On the other hand, (I thought it was me too) things do seem to look a little noisier here these days pretty much everywhere on the "clean" channels, and of course we don't live in a "perfect world". I haven't seen anything new here except CCI* that can directly be "pinned" on such and such new station coming on the air, and I haven't seen that the newer local DT's coming on the air on adjacent, or nearly adjacent channels affect the other locals in any way nor have I been able to directly attribute more noise on the "clean" channels to any of the new locals coming on the air. Anyhow, I suppose with so much RF flying around and with more to come, in the real world, in many circumstances I think things are just bound to be noisier. My guess is, things will "quiet down again" after analog shut off.
* - Such as "sparkles" most likely from WUAB-DT often seen as CCI to WTTE -- the sparkles were never there before WUAB-DT hit the airwaves, but are present just about anytime I see WTTE nowadays.
I do know that if one's receiver and antenna is in the middle of "nowhere", it certianly seems to get much, much less noisier all around. I haven't been to such a spot in a few years, but, I know of one such area, in and around Blue Creek, Ohio. There are only a few TV transmitters(the close ones aren't extroidanarily high powered ones either) closer than 75 miles. From a spot on a ridge(1160FT ASL) there, in the middle of the forest using a small Yagi(no preamp) mounted on a fence post, just about everything within 75 miles(Cincy, Morehead, KYHuntington, WV/etc) are locals, and the Dayton and Columbus VHF's(90 Miles) are locals. And, the "snow" is much, much less noisier over there, even when using the cheap tuner on a $20 portable Black and white TV.
In 1998, From an even "quieter" spot at "the cabin" near that location(1/2 mile away and down the hill, at 800FT ASL), a spot which has far more significant terrain issues than I have here although I didn't "offically" log it, I pulled in my most distant tropo catch so far, with the same cheap B&W TV and a small, hand rotatable Yagi 15' above ground. That catch was, KLVY 11, Fargo, ND, a little over 900 Miles from that location. Also, on that same evening, I saw many other stations with perfect quality, Including Indy, Louisville and Terre Haute. Had perfect reception from WKMJ 68 all night, that being the first time I had seen WKMJ. Granted, I think it was a "Super Tropo" from the West sort of evening, but I was still surprised Because of the terrain blockage issues in every direction "down in the holler" there, only WLWT 5 Cincy(76 Miles) and WSAZ 3 Huntington are locals(and just barely), WDTN 2 semi-local. The hills even block a station from 12 miles away, WPBO 42 Portsmouth.
There is also a ridge nearby there which is among the highest spots in Ohio at around 1320FT ASL, the ridge is actually cleared off, and has farms, and houses with TV antennas on top ... That, or a similar location is where I would like to put my tower(s) for Dx'ing someday!
Anyhow, I'd really like to see a VHF/UHF noise study performed with sensitive equipment, and concerning the increasing amount of RF present from NTSC and ATSC stations. At the very least, It seems such a study would be a very difficult undertaking, in order to distinguish CC noise from other sources/etc, since stations from 100's of miles away can and certianly do often raise noise levels a bit on the channel they are broadcasting on, even under dead band conditions.
