HARD REBOOT! Clear that leaky memory.

WMAQ is on digital channel 29 and is a line of sight signal that is somewhere in the neighborhood of about 48 miles and is transmitted at about a power level of 167 Kw - which is not a lot of power, especiallly at 48 miles.

I would suggest that you buy a better UHF antenna like the XG 91 and a good Pre amplifier such as a Channel Master CM 7777 and a good antenna rotor because you have signals coming from all directions at your location and the XG 91 is a highly directional antenna.

Look at your TV fool report to see what I mean.

The XG 91 will not work well on any station in your area that is less then channel 22, so you will also need some sort of good VHF antenna if you wish to watch WWTO, WGN, WLS, WYCC, WYIN, or WOCK.

Antenna is a winegard HD8200p
AMp is an Ap 8275 winegard
On a rotor 35 feet up on the roof
Signal on NBC is 100% according to the tuner, was the weather or station or the crummy 622 not the antenna!!!

So do you want a shoulder to cry on - or a tissue to wipe the tears from your eyes?

Lot's of things disrupts signals.

Everything from migrating birds to airplanes to the leaves on the trees to rain to snow to fog.

Anything between you and the signal can temporarily block your signal, there by corrupting it and making it unwatchable.

I too also have a Winegard 8200 U antenna and a Channel Master CM 7777 pre amp.

Maybe you need a FM trap on your line.

Maybe a cop shop in your area has a strong transmitter that is interfering with your reception.

Could be one of 100 things happening here.

HOW RUDE!!

yes how rude!!!!
I found my prob, the 622 is a pos, did a hard rebott and the prob went away, the dtv pal worked fine so I knew it was a 622 problem.

I would suggest that you actually read the post before you start being rude to torwards the more experienced forum members here. There was no indication that what he was experienceing was a reception problem at all. Yet you jump right in and spout that he is in a poor location with a poor antenna, then procede in another post to be very rude and tell things that is already a known. You should ask questions before instantly ASSuming you know the whole story.

The problem at hand was a "choppy" picture. This can be caused by many issues that do not involve the antenna or reception. In fact, an antenna issue would NOT cause a problem as he indicated. You need to learn some manners. Bite your tongue and THINK about the problem(s) you act like you are an expert on, before you so matter-of-factly reply.

Glad to see there are some people here who still can comprehend a sentence.
I spoke to another member a friend of mine on avs forums and he confirmed it was a problem on NBC's end not on mine. He had the same issue.

I heard some DTV stations cut their power by over 90%, making reception nearly impossible.

Many stations that have reverted to VHF assignments have dramatically cut their transmitter power, in some cases by over 90%! Some stations mistakenly thought they could save money by cutting their power while reaching the same number of viewers.

Getting VHF stations
