If there's anybody in the Atlanta area, getting WGCL OTA, have you had any problems in the last week? I went from great reception to NO reception in one day and I haven't been able to get any signal in a week. No changes as home. And I even used a backup SIR-T151 STB with the same results. All other DTV stations are fine... just WGCL.
Antenna Adjacent channel causing reception problem
Read-only archive
hey Grumpy... I've had the same problem of late... but, I've had them before... I live 85 to 90 miles away and thought they were using low power, when I couldn't get them... fortunately for me I live about 20 miles from the Macon CBS station... the only Atlanta station I get around the clock with no problems is WUPA, which I thought was probably because they were at full power... the rest are great after dark and so so (in and out) during the day... under ideal conditions, I get a lock on low power ATLC 42, which was WTHC when it first locked in... is either of the PBS stations on the air yet... I seen where WGTV had applied for a relocation to channel 12... maybe that's their holdup... I also remember WGCL had some kind of technical problem a couple of months ago and were down a couple of weeks, waiting on replacement parts...
Grumpy,
Having seen you antenna and your location during your ISF calibration here is what I would suggest.
Get a channel Master 4228 and a rotor. That will likely solve your problem and also improve consistency with the others. The antenna you have does not have enough real gain. NBC should still work and if not then you can always add a VHF only like many in Atlanta have done.

Just got off the phone and this is unofficially official... (that means the
little birdie who told me is to remain anonymous)
WTBS, 20, increased their power to 1 megawatts. This may cause adjacent
channel interference and noise floor problems with WGCL, 19. Those receivers
that excel at selectivity should not be affected. Sorry, don?t know which ones
those are but in general the OTA only receivers do better than the satellite
receivers I am told.
The only solution is for WGCL to increase their power which will require FCC
approval and a huge capitol outlay to build out their plant. WGCL has done
nothing on their end to cause any of the problems that may be occurring for
some individuals.
Also let us not forget that satellite receivers received new software last
week forcing some to use 19 rather than 46 to receive WGCL DTV. Please give
this a try before posting a problem.
This is not anybodies fault and beyond the control of WGCL.
The broadcasters who monitor this board would sincerely appreciate the group
not jumping to erroneous conclusions in the future and please simply report
your problem without any whining; Just the facts please. Please include your
receiver model number to assist the group and broadcasters in making sense of
yours and others problems.

Well... that stinks, I guess. The information is valuable, but certainly not what I wanted to hear. I won't spend any more effort on getting a 4228 on the roof, since it's apparently not going to help (I read on the ahdtv site where another Atlantan had 4228 and lost WGCL too). So much for Football season weekends 
, but at least I'll be getting more things done around the house (wife ->

Grumpy - where are you located? I'm near Suwanee and still get 46 with my 4228 and a rotor and pre-amp.

Grumpy,
I had another Atlantan contact me about this and both of you are using the same antenna in the same conditions.
From that email...
Actually that is what I said, too much power from WTBS is causing tuning
problems with the weakling WGCL right next to it. Your receiver keeps seeing
the lobes of WTBS in the WGCL channel incresing the noise floor especially if
the WGCL is already noisey. As Gain increases so does direction and
selectivity. The antenna I suggested would solve your problem by:
By not using a preamp you have reduced noise
By increasing the gain of WGCL you have reduced noise even with a preamp
By adjusting the antenna you might detune WTBS reducing adjacent channel
interference and noise on WGCL
FACT: your antenna does NOT have enough gain regardless of how well it has
performed up to now.
FACT: most folks do not have enough antenna and are compensating with preamps
Grumpy, you won't know until you do it. It will cost you $50. I have a 4228 laying around here but considering how far apart we are...
Just order it.

Richard- I believe none of your suggestions will work. I gave this problem a lot of thought for a Washington case (KEPR) and I concluded that when an adjacent channel station is too powerful (by a factor of more than 20 or so), if the towers are separated by less than one degree, there is no practical way to receive the weaker station.
I am not sure whether the failure is due to out-of-channel emissions by the strong station or if it is an AGC failure in the receiver. -Ken

Ken,
We have a had a fairly rough week in Atlanta over this and the engineering staffs are already overwhelmed and quite aware of the complaints.
On the other hand they have proven for themselves time and time again by actually showing up at the customers location that the antenna system is ALWAYS marginal and by installing the correct one the problem(s) is solved.
I calibrated Grumpies display, I have seen his house and his antenna and he was marginal before WTBS increased their power. I told him then I was surprised the system was working and he did go on to explain all his consistency problems but since he does most of his viewing at night he was not concerned since it seemed to cooperate during those hours.
I am in multipath hell running a very high gain antenna and have not had the first problem. Most antenna systems installed by end users are designed to get by, keep it off the roof, or put where they really do not belong due to poor appearance and are marginal. That is never a problem until things like this come along...
The Atlanta group also provides a free loaner CM4228 but it is in a crate to protect it and is not setup for actual installation on a roof. Many have used it only to buy one for themselves having great success in the end.

I retract the claim that none of your suggestions will work. I had assumed that WTBS was far above the power limit that would allow WGCL to be received. There is the possibility that WTBS is only marginally too powerful. I had considered that unlikely, but it appears to be the case in Atlanta. In such a case, the added reception difficulty can cause marginally working antenna systems to fail. (I
KQ6QV...This is off subject, I just noticed that you live in San Jose...My wife and I just moved from there about a year and 1/2 ago...We lived in San Jose, Saratoga, Campbell, Los Gatos...My stomping grounds were around Hamilton Ave and Lawrence Expressway...By the Malls... 
How do you like those gas prices?...Just for your own info...We moved because the housing was so ridiculous...The house we bought here in Acworth Ga. would have cost 1.5 Million in San Jose...We only paid 210,000.00 here!...plus gas is the cheapest in the U.S here...anyways, glad to hear from a fellow San Jose-an...

I've got a 4228 in the attic with a CM preamp about 20 miles from the towers and I'm getting both TBS and WGCL just fine.
Richard,
All the other stations are still fine. It's not the $50 that is stopping me, it's the $150-200 that an installer wants to go up there... As you may recall, the backside of my house is down a STEEP hill, so it's a three story drop to the deck below, and the guy that installed the current antenna had a hard time balancing on the awkward ridge up there - and he was a pro! There's no way I'm crawling up there. Not for just CSI. I'll miss the football, but the rest of CBS just isn't worth a possible broken pelvis. And after spending $500 on the T165, $1000 on the Lumagen, and $$$ for the calibration (I omit the exact number out of courtesy to Richard - it was a fair price), I can't justify spending any more on TV right now.
Allen, I'm in Ellenwood, near Stockbridge, about 20 miles SE of Midtown. Yes, I have two pickup trucks - one beat up one for six days and a clean one for Sunday. I have cows grazing in the center of my subdivision.

That's the other reason mine is in the attic. I'm glad I didn't have to go outside. Mine is also 3 stories in the rear with a concrete patio below most of it.

Richard,
What do you think of trying a 4228 in my attic? I figured It'd be too low, but for $50 and 50 feet of RG6... I could keep both, and switch between them as needed...
Ken, any advice on what to look for in a simple A/B switch?

Grumpy,
You can alwys try it and all you have to lose is your time.
But...
You are taking the advantages of changing the antenna and burying them by putting it in the attic. You may very well end up with no change. On the other hand it might do the trick...
Let us know.
