So are you saying the power increase has now been implemented?

Awesome news. I hope it helps. I hope you can convince sister station WSET down here to do a power boost too if their move back to VHF is as problematic as VHF moves have been elsewhere.

I did yet another rescan. The locals are now at 4.1, 5.1 etc., even without a box. Go figure.
Its about time they did something logical.

Robert,
I had a solid signal back in June, 99% on My DISH 612/722 boxes. Today I can't get a lock on your signal at all. Still getting WUSA right around 99%.

WNUV CW54 still has glitches when they show syndicated HD shows. Depending on what equipment you are using, the show will blink to a screen that say "off air" for a split second. I am currently watching House of Payne while this is occurring. I am using a USDTV HD box OTA. This is the only one that reacts this way.

Solid signal in Southern York County, PA (east of I-83). I do get dropouts during certian weather events. But generally very good reception.

As of today, WJLA is completely unusable from here in Elkridge, MD. It's gotten a great deal worse. Almost impossible to get a signal lock at all. Haven't made any changes at all on this end, just tried to watch RTN and decided to poke my head over here when I couldn't. It's not amplifier overload, WUSA 9 and all UHF channels are fine. Ideas?

edit: Hooked a tuner directly to the antenna, same issue. WUSA is 100% perfect right now, WJLA has a very strong signal but only a 35% S/N ratio and will not lock. It was an 85-90% S/N ratio previously (after adding a low VHF filter). Interestingly enough, a homemade UHF Yagi antenna with extreme negative gain on VHF 7 I have can lock the channel for brief periods of time. My guess at this point is extreme multipath (that Yagi I made locks 11 and 13 from the back without any issue too - I love that antenna). I almost feel bad for saying this, but from my location I think 52kW is actually too much! lol

Will try an attenuator at the antenna, even if it's just academic to do so. I don't need WUSA tonight for anything!

edit 2: Attenuator = no love. It's a variable 0-20dB attenuator. WUSA disappears completely about 25% on the knob, WJLA stays at 100% strength and a really bad S/N ratio until I'm almost at the maximum 20dB, then it disappears. Using a Y5-7-13 in an attic. Gotta be multipath that wasn't there yesterday. Again, I realize this is academic at best, and I've already decided to go with a FiOS Locals Only package (Sunday!!!) to solve my DTV reception issues with WJLA, WUSA, WBAL and WJZ.

Not worried about it for my own purposes. Just trying to provide meaningful feedback while I still have the equipment to do so in place. eBay firesale starts Monday! LOL.

Solid signal for 7 now in Annapolis MD near Annapolis High School. Much stronger than 9, which I still struggle with. To round out the VHF in our area, 11 and 13 from Baltimore are fine. Prior to today, I struggled with 7 and 9 -- now only 9.

I can now receive channel 7 (WJLA) with an EZ-HD antenna http://www.dennysantennaservice.com/...v_Antenna.html (same as an RCA ANT751) leaning against the wall in a second-floor bedroom, connected to a Channel Master CM 7777 preamp and a Zenith DTT901 digital converter box. My zip code is 21046.

I still can't receive channel 9 (WUSA) with the same setup.

(I can still receive channels 7 and 9 with my rooftop (old) CM 4228 antenna and CM 7777 preamp.)

WJLA went from 99% strength and zero dropouts to 75-80% strength with the occasional dropout here in College Park. WUSA is still at 99% strength. I'm using a RCA ANT751 antenna and have tried swapping between Winegard HDP-269 and AP8700 pre-amps. But I still get dropouts either way now.

I believe that WJLA gave me 100% signal before. Now it is at 85% at all antenna angles from 0 t0 260 degrees. It drops to as low as 75% as I rotate the attic 4228 antenna to 360 degrees. The performance at 85% is excellent, but I never saw the insensitivity to antenna angle before. I get good signals from all the channels except WUBT, which doesn't go above 5% at any angle.
This was my report of tests about 9:30 AM. Now at 2:00 PM the signal is at 100% instead of 85%, and still not sensitive to antenna angle.

Robert, thank you and WJLA for putting forth the effort on this. I really think you guys are doing the broadcast TV community a major service by testing out increased VHF power for DTV.

WJLA has been mostly unwatchable for the last few days for me here in Fredericksburg. It was very solid before. My tuner (HDHomerun) shows a "Signal Quality" alternating between 0% and 40% and a "Symbol Quality" at a constant 0%. If possible please return it to the way it was now that the new shows are starting up.

Thursday night there was a glitch with Comcast in my area. Or at least the feed going to my house. It happened at around 8:10 PM. I was watching Bones in HD and for about a minute or so the channel changed to something else and then eventually it went back to Bones. At the same time I was taping Weekend Update on NBC. On my tape at about the same time it went from NBC to some local county feed for a minute or so and then returned back to NBC.

It was very weird. Has anyone else experienced something similar?

Robert,

The signal appears to be more stable here in Shady Side, MD (30 miles directly East of DC). Before you increased power, my picture would pixelate often. In addition, I don't need to have my antenna so precisely pointed as before for channel 7.

I have an outdoor (roof-mounted) fringe VHF/UHF yagi with CM 7777 preamp and receive all Baltimore, DC area, and Salisbury stations well at my location.

What type of polarization are you guys running? I've heard that some of the DTV coverage problems can be fixed on VHF by running elliptical or circular polarization vice horizontal. This type of change may be especially helpful for people using indoor antennas or maybe even attempting to watch your ATSC-M/H broadcast in the future.

FYI, WJLA 7 is coming in fine again tonight. Maybe they put the power level back or adjusted something else?

edit: while most of my rediculously elaborate TV setup has been unhooked since the original post and hidden from prying Verizon eyes, that UHF Yagi I mentioned before is still hooked up, and I'm still getting WJLA on it! (And not WUSA, so I don't believe Tropo is at work here). I *think* they're still at 52kW and must have changed something else. Polarization? Robert?

Are you farther out fringe folks still receiving WJLA tonight? It's looking very very good from Elkridge, MD as compared with yesterday.

Yes, I got a solid signal in Fredericksburg last night and it seems to still be solid this morning (no changes in my setup).

Comcast DC with direct coax connection -- has anyone else lost MHz this morning? It was there yesterday (at 22.1 - 10) and now , poof, gone. I rescanned and I'm significantly down on the number of analog stations being tuned in -- and some of digitals that were in the clear are disappearing, now, too. In addition to Mhz disappearing, Fox HD, which was coming in around 16 has moved to 5.1 and MPT HD and subchannels-- which were coming in around 16.3, 4, 5 is now blank .... apparently moved back to 22, -- which may be why MHZ's ten subchannels have disappeared. Did any of you get a mailing about reduction /movement of channels? Losing MHz is an unhappy surprise... though, it is good that MPT is back - presumably for good...

Also, do you get AMC and TCM in the clear in HD? They are showing up as being 'scrambled' here, but others in Md have told me they get it without a STB.

Thanks for any info you can share.

I noticed that 66.1 and 66.2 had rock solid video yesterday, but 66.3 and 66.4 would pixilate when there was significant movement. Similarly, 7.1 was solid during a football game, but 7.3 similarly seemed bit starved. Does anyone know if the less important sub channels get less forward error correction? I was on an outstanding antenna when I observed this (over 200 feet above ground level AGL, line of sight, typical 10 dBmV or more signal strength, signal quality tested excellent on my Blonder Tongue BTPDA-4)

Yes.

Mike, have you had any luck with Virginia Public Television at the high rise building in Mclean?
