It is 11:47 am and I am watching a very bad signal of RTN on channel 45. I live off of Cheshire Bridge Rd. The funny thing is they must be taking a live feed or are time shifting differently than WSB 2.2. The programs on WSB 2.2 is different than 45 analog. Anybody have an idea of what I am picking up?

Picking up RTN on channel 45 analog

There are 2 applications for a analog channel 45 in Atlanta but until analog 46 shuts down in February I guess we wont see a CP issued for analog 45. The applications is by EBC Atlanta.

WYGA-CA is operating under STA. It is owned by Equity Broadcasting, former owner of RTN. Operating with 2 kW. I suspect they are broadcasting from one of the towers on Cheshire Bridge Rd.
I thought this was not OK. Is there any interference with WGCL? (The Wikipedia article said WGCL protested).

No, there are LP stations right next to full-powered stations all over the place. New York City has several of these (25-26, 31-32, 41-42).
At the power levels they're required to run, I can't imagine any interference to the full-powered station, though the full-powered station no doubt stomps on the LP pretty badly.

Actually, since 46's tower is in the same place, 46 is bleeding all over 45. It is a direct satellite feed. The screen goes blank where there should be local inserts.
Well, now that I think about it, I have no idea of who is bleeding over who. I am so close to the two big towers, that I have trouble picking up signals on those towers.

I think you are talking about the site at the old 46 studio site off of Briarcliff.
WYGA-CA is apparently just on the air this way to keep their license until WGCL-TV analog 46 signs off in February. Until then, they are just keeping something OTA to meet FCC regulations.
Why not make a deal to rebroadcast WGCL on 45? The owner of another LPTV made a similar deal with a full power station to do so (WATC 57 with WSKC-CA 22, which broadcasts from the same tower at Sweat Mountain in NE Cobb) until they could do something. WGCL probably would not complain (they have complained under the current arrangement).
I thought having two ajacent signals on the same tower was a bad idea from an engineering standpoint, let alone in the same town.

Stations on adjacent channels CAN exist if done right... If Channel 45 and 46 were further apart, and not on the same tower, ti'd be Ok. There would be no problem with them being in the same town.
You see, TV channels, while close in number are far off in frequency. For instance, Channel 6 audio is at 87.75 FM and Channel 7 is WAAAYYY up in the 110+mhz range.
They aren't as close as they seem, so you are either REALLY close to the transmitter site or something's wrong.

Having two adjacent signals on the same tower is better than having them on different towers!
In the analog world the FCC has required at least one blank channel to separate stations with nearby sites. (it used to be five blank channels...)
However, with digital they've allowed the use of adjacent channels if the sites are close enough. For example, in Milwaukee where there are digitals on channels 33, 34, and 35 (and an analog on 36); channels 33, 35, and 36 are on the same tower and 34 is less than two miles away.
They wouldn't have allowed that situation if channel 34 was 20 miles away. Because then, channel 34's strong signal near its tower would overwhelm reception of channels 33 and 35. If all four stations' antennas are nearby, then no one station is much stronger than its neighbors.
With low-power stations like channel 45, they're allowing this pretty much as a last-resort situation. Apparently WYGA can't stay on the channel it was on, and couldn't find any better channel, so they landed on 45 and will accept any interference they receive from WGCL. (probably moderated by the knowledge WGCL's analog signal on channel 46 is going away in 90 days!)
There is in fact no gap between most adjacently-numbered TV channels. There is no gap between 45 and 46, nor between 10 and 11, nor between 2 and 3.
The only channel pairs that have a gap between them:
4-5: gap of 4MHz, 2/3 of a TV channel. It's used by aircraft navigation beacons.
6-7: gap of 86MHz, 14-1/3 TV channels. Used by FM radio, aircraft, NOAA weather radio, and two-way services.
13-14: gap of 254MHz, 42-1/3 TV channels. Used by military, two-way, and hams.
So 4 & 5 can be used in the same city without restrictions. (as they are here in Nashville) 6 & 7 can be used (as they are in MIami), and 13 & 14 can be used. (as they are in Houston)
Someone mentioned that I must be really close to the tower. I am very close to the base of the towers (there are two next to each other that have many TV and FMs on them). I live within 300 feet of the WQXI-AM 790 site. I guess that is probably lesst than .25-.5 miles from the base of the tower. I have always had trouble receiving OTA analog TV signals because the signals shoot over me.

Not only are you going to have problems with signals overshooting you, but the ones you do get will overload your radios and tv's

You are absolutely correct. Been having trouble for 15 years. Add to that all of the RF bleed from all of the AM stations across the street.
In 2000 it took a BellSouth engineer and I several months to figure out why my DSL would go out around mid-morning and start working again mid-afternoon. I finally decided to look up all of the AM stations on the FCC database and figured out that 1190 AM is critical hours at 2300 watts and then 25,000 watts daytime. I called the BellSouth engineer and asked about the frequencies used by DSL... well, on the low end it starts at 1000 khz. Long story short, everytime 1190 AM went to 25,000 watts, my DSL would quit working. The BellSouth engineer and I finally decided there was no way to make the DSL work because an RF filter kills some of the frequencies used by DSL.
Without RF filters, I can hear WQXI-AM 790 on all telephones, fire alarm speakers, and modems. So, basically, I am in RF/receptoin hell here.
