So, not sure anyone else noticed, but suddenly WIAV-LD 58.1 (RF 44) is on the air. This morning, it was running Spanish-language E/I programming in widescreen 480i, but now I'm getting like 5% symbol quality (100% signal quality--which is greater than 35 dB MER--go figure) and a continuous blur of pixels.

FYI, from their website:

MHz Networks 30.1-30.6 Off Air Due to Tower Maintenance
Beginning at 10 AM ET on Thursday, October 3, MHz Networks digital broadcast channels 30.1-30.6 will be off air due to scheduled maintenance on our WNVC broadcast tower in Falls Church.

Pending successful work completion, MHz channels should return on air by the end of the day, around 5 PM ET.

In lieu of watching via broadcast in the DC area, MHz Worldview is available via iOS and Android apps, Google TV, Roku, and online.

I'm measuring the expected signal strength of digital 44 relative to channel 48 which both broadcast from the towers by American University. I'm nine miles East-Northeast of those transmitters. My 44 is about seventeen dB weaker than my 48, but even though my Sencore 1453i calculates fewer than one emulated bit error per 100,000,000 bits, and a C/N ratio of 26dB, the picture is totally broken up as you described earlier this week.

What is 14.2 supposed to be? When I enter it in, it switches to 49.2 (New Tang Dynasty). 49.1 is QVC, while 49.3 is black but shows QVC as the id. This, on my Magnavox/Funai DVDR.

GetTV , a new television network owned by Sony Picture Entertainment, is expected to begin Washington, DC carriage broadcast on WDFC 14.2 (virtual), which is broadcast on UHF 15, some time this October. Its content will primarily be feature films.

Thanks, I did not know this. Any idea how their programming might differ from AntTV which also shows Sony movies? Maybe the licensing is expiring?

At about 5:15 PM, I just began watching my first relatively stable programming on WIAV 58.1 It is a low budget interview show called Valderrama's America. The interviewee is Keith Washington, said to be the Deputy Director of Prince George's Country's Homeland Security Department, but since there is a banner making reference to an upcoming September, 2006 election for the House of Delegates, 26th District, this interview is just some kind of test broadcast.

The audio is scratchy, and the picture breaking up just a little, even though the signal strength in dBmV, S/N ratio and emulated bit error rate are all good. I'm measuring -25dBmV coming off an 8-bay Antennas Direct antenna outside of College Park, MD, 9 miles to the east by northeast of the transmitter. The signal level is 25 dB less than UHF 48, which travels over the same signal path, but as I have reported elsewhere in these forums, my signal goes through a lot of vegetation, so it is only a line of sight signal path if suburban Maryland were defoliated. 6:02 PM update, the picture and audio are now perfectly stable.

There is a horizontal crawl overlay making reference to an upcoming, a September 2006 primary for the Maryland House of Delegates, in which the interviewee is a candidate, and then it cut to an election ad of sorts for another Valderrama.

David Valderrama was listed in the credits as the interviewer, Kris Valderrama as the east coast reporter and Vida Valderama as their west coast reporter.

Update at 6:02. Two guys are seated in an office, talking in Spanish, and each has manuscripts in front of him. Unfortunately, like a lot of Americans, when I hear Spanish, I can only pluck out a few nouns here and there. This interview is being captured by a single camera, albeit with an operator, who occasionally widens the shot to include both participants and then zooms in on one when he is speaking at length.

A fixed banner went up on the bottom of the screen with a 202- phone number, followed by "OFFICINA". Now it says "ABOGADO" where it had previously said officina.

Wikipedia says Kris Valderrama is female, and won that 2006 election and subsequent re-elections and presently serves in the Maryland House of Delegates.

I did not recognize the name of Keith Washington, who I now see was convicted less than two years later for shooting two furniture deliverymen, was sentenced to 45 years in jail, and, more recently, had another of his motions for retrial turned down. While I will investigate this further for my own purposes, I will not be posting my additional findings on that matter here.

MHz Network's 30.12 is now 12-hour Turkish, 12-hour Nigerian/African programming.


Viewers can watch the channel 12 hours daily, from noon to midnight each day, on digital broadcast channel 30.12.

TRT Turk, the international TV channel of the Turkish Radio and Television Corporation, was created to enhance the understanding of the possibilities Turkey and Turkic Republics possess in various business fields through programs aiming at the Caucasus and Central Asia.

The channel also promotes Turkish people and culture in broadcasts comprised of education, drama, entertainment, music programs and news.


ARISE News was founded by Nigerian publisher Nduka Obaigbena, who dreamed of creating a global news channel connecting all the “colors and shades of news” around the globe with an emphasis of reporting about Africa. With a team of world-class journalists, behind-the-scenes and in front of the camera, ARISE News covers the compelling issues of our time from every angle.

Back in the late 1990s, when I used to advertise my satellite antenna service business heavily in the Yellow Pages, I got a call from someone who wanted to know if I could get him Nigerian television via satellite. I told him I didn't know of any such channel but that he should call the Nigerian Embassy and ask them, because if such a source existed, they'd have to know about it. He replied, "This is the Nigerian Embassy". As you might imagine, the project went no further than that..

I posted this already over at

 

http://www.avsforum.com/t/1496231/need-antenna-recommendation-for-northern-virginia#post_23875872

 

but was told to also post it here.  

 

I would like an antenna recommendation for attic installation (attic first because there is already a coax cable available from there to the tv).

 

TV Fool: http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3d46ae9ea40ec79c  [it's to my actual address in zip 22032

 

- 2 stations are LOS, the rest are 1Edge or 2Edge]

 

I was intrigued by the Mohu Leaf Ultimate HDTV Antenna and bought one to try next to the tv (I've had cable for 20 years). It gives me some of the local channels (facing east or north works best, not NE as I expected):

 

Strong: WTTG 5.1 (FOX), WUSA 9 (CBS), WDCA 20 (MyN), WNVC 30.1 (MHz)

Weak (Often loose signal): WRC 4 (NBC), WETA 26 (PBS)

Very Weak (comes in once in awhile): WJLA 7 (ABC), WHUT 33 (PBS)

 

There are several "green" channels that I expected to pull in but could not (no matter the placement of the Leaf Antenna).

 

Since there was an existing coax from the tv to the attic I decided to experiment by putting the Leaf Antenna in the attic. No matter the direction I pointed it (generally NE, trying NNE to ENE) I got poorer results than when it was next to the tv (still got the strong stations but could not pull in weak ones at all). It claims to get a 15 DB gain.


I've looked at a number of antennas, but I'm not sure which one would work best in my circumstance. At a minimum I'd like to get all the DC stations (green and maybe all the yellow). Ideally, I'd like to also pull in the Baltimore stations (about 50 miles). Any recommendations (and can you please state why you recommend one antenna over another)?

 

Recommendations on the other thread were:

- HBU-22 (70" boom length) and Winegard 7694 (78" boom length) for DC Stations
- HBU-33 (80" boom length) and Winegard 7696 (99" boom lenght) for Baltimore Stations.

 

I need to check if they will fit into the attic if they are aimed NE (not sure I want to put it on the roof).

 

My research suggested the Clearstream 2V (C2-V-CJM) might work well (and it is certainly a size that will easily fit in the attic), but one comment was that it would be good for the DC stations but not for the Baltimore stations.

 

Can anyone in 20032 (near Target) share what works for them? Thanks!

 

Thanks!

post #13573 of 13749
I used to live in 22032 and had an antenna in my attic that worked well. I was high enough that I had LOS to all Washington stations, and with modest amplification I could get Baltimore stations too.

Or are you really in 20032? You wrote both numbers above.

I used to maintain a dozen, cut-to-channel antennas for The Fairfax at Ft. Belvoir in area cide 22032, a 500+ occupant assisted care facility, and while they all worked well, you certainly wouldn't be inclined to replicate that installation. They switched the entire property over to franchised cable about four years ago.

But but... Ft. Belvoir is not in 22032.

AntAltMike,

Could you add all of the low-power digital stations that are now available in the region to your listing on Post #1, if possible? You might indicate in your comments whether they are in the application stage or they are licensed and whether they are actively on the air.

Thanks

I don't have the resources to do a comprehensive job of contemperaneously maintaining such a list that is developed from FCC filings, but I could maintain a list of member-submitted notifications regarding their own observations, similar to what this opening thread maintained long before I inherited it and streamlined its format. I could post a suggested format for members forwarding their information to me that includes where and when they were observed to be operational, as well as any user-supplied links to published information regarding their operation.

Does anyone else experience the signal for WNUV CW 54 Baltimore completely dropping at around 12:10am. It happens to me every night around that time and I'm wondering if they are doing work on their antenna. Seems weird that it would go out at that time and it's been doing for the past couple of weeks.

WNUV has experimental authority to test with DVB-S2 modulation over night. My auto scanner stopped running some time last night but I see where it was undecodable but still with lots of signal strength after midnight the night before.

I figured they had to be testing something. Of course the night I posted this it worked fine. Figures!!!

When did WETA start transmitting in 1080i? I know it was 720p for most of this year. It's the reason I watch Masterpiece on MPT because it's 1080i.

Yes, MPT shows many of the same shows, and in 1080i. Perhaps that's why they switched.

Over the Air Antenna Question:
I live in Bethesda and want to watch the Ravens on Monday Night Football 12/16. Can anyone get WBAL-TV channel 11 from the DC area? I have never been able to during the analog days or post digital days. The tower looks to be the same as channel 13. I get 13 most of the time so why can I not get channel 11?

The only reason I switched to antenna 5 years ago was to watch the Ravens on HDTV. since the lame DC stations never showed the Ravens until this year (after they became the Superbowl champs).

P.S. MY antenna is the Winegard 7694 from 4-5 years ago

Probably because the strong signals from 7 and 9 produce a beat on 11 that destroys the Baltimore signal, in which case you need a channel 9 trap, or channel 11 bandpass, or other filter system to equalize strong and weak signals.

Other posters here might have or know where to get such.
post #13585 of 13749
I live in Alexandria and get WBAL and WJZ. I don't have the best VHF antenna, so they both teeter near the edge of decoding, but the signal is such that if I put it higher and had a better antenna, I'm sure I could stabilize them both.

http://www.rabbitears.info/tvdx/signal_graph/1019EECD/tuner1/WBAL-TV
http://www.rabbitears.info/tvdx/signal_graph/1019EECD/tuner1/WJZ-TV

I tend to agree with joblo, if only because it impacts 11 but not 13. If it was second harmonics from FM, I'd expect to see it on both, same for noise, etc. I think you'll just have to fidget with the positioning, or at least, that's what I would do to start with.

Could be interference from channel 12 or possibly 2nd harmonic interference from the screechy 99.5 HD transmitter in Bethesda. Are you still using the FM trap? Is the antenna in the attic? I am assuming the antenna is pointed towards Baltimore.

As Trip mentioned, there is plenty of decodeable signal available on WBAL, even in Northern VA. I even see it way out in Centreville with an attic antenna, but not very watchable due to Dulles airport & aluminum siding.

What is happening at WUSA? I have had near zero signal in Damascus MD since last night; swung the antenna 1-360 degrees no luck. Their signal strength have been weak and intermittent for a while now. All other Washington stations except channel 7) are showing 90+ signal strength on my TV. Channel 7 is aout 70+.

Yes, thanks again for the advice from couple of years ago, the $5 FM trap worked well for channel 13 reducing interference from FM 107.3, but now not as much anymore. I'm not sure if the large oak trees north of my house have grown blocking anything north of me or other interference. Maybe you are right about 99.5, that station comes in very strong around my house . What can I do about that ? Bigger antenna or could you recommend a specialized FM trap?

I am within a mile of 4, 5, 7, and 9 . I also looked at my signal meter strength info on the TV and I get:
Channels 4, 5, 7, and 9 SNR(dB) = between 25 to 35 good reception all the time
Channel 13 SNR(dB) = between 10 to19, usually early in the morning when it's above 15 i get reception
Channel 11 SNR (dB)= 2- 5 , no reception

You can buy a cheap channel 11 bandpass filter here for four bucks http://www.channelmasterstore.com/JOIN_TENNA_CM_0581_p/cm-0581.htm It should weaken every possible interfering channel except channel 12 by about 20dB.

It will allow you to determine whether the degradation is caused by out of band signals or from multipath. If it works for you, we might be able to help you develop a cheap solution. You might want to buy a channel 13 jointenna at the same time, because it would only cost you another $4 and you'd probably get a break on combined shipping.

All of my Join-tennas are at least 20 years old; do they still have plastic cases?

Within a mile of full power transmitters, I would want filters, traps, amps, and everything else encased in metal.

Also, for more complete FM rejection, I would recommend one or more HLSJs in lieu of FM traps, and I would recommend quad-shielded coax in pristine condition for transmission line.
