WRDZ was sold and would become WMIH. The WMIH owners moved the studios to Playhouse Square (The Hanna Building if I'm not mistaken). Now that's it's Radio Disney they probably don't even have a local studio, all they need is a satellite dish at the transmitter site. I can't say this for certain but I would not be surprised since all they need to insert locally is an automated legal ID at the top of the hour on an otherwise 100% satellite-delivered program stream.
Yes, it's mostly a satellite feed. They do have a small studio in Broadview Heights located off of Ken Mar Industrial Parkway, right behind the newly built Giant Eagle. I guess they only use it to record commercials for local events and for their public affairs program that airs every Sunday morning. I did call the local studios a long time ago to inform them that they were only broadcasting the left stereo channel of the satellite feed instead of mixing both channels together. I don't know if they ever fixed that. Since they installed that stupid HD transmitter, the audio has been terrible.

I've done that too to WMJI about 12 years ago. I noticed that a certain oldie that was released as a stereo single was playing in mono. Then I noticed that everything was in mono whenever a certain DJ was on the air. I finally contacted that DJ via e-mail when I heard a record started out in mono but magically bloomed into stereo shortly after the song began. This happened at the end of that DJ's shift. I thought that the DJ might have been using mono headphones that bridged the on-air console. I said something to that fact in the e-mail. I never got a reply from that DJ, and shortly after that DJ was no longer at that station. I hope they did not can the DJ based on my e-mail. I only sent it to him, but it was the company's e-mail so it might have been read by management.

I remember when 1220 was the original home of WKNR, and the night signal dropped off rather reliably on Route 18 exactly at the Summit-Medina County line (Medina Line Rd.).

It presumably still does, but I don't listen to the current programming on 1220...

I remember an incident back sometime in the 1970s (IIRC) when I phoned WDBN, Medina (94.9, now WQMX) after hearing them broadcasting taped music at the wrong speed for a very long time one evening. Apparently nobody at the station was listening to what they were sending out and seemed quite shocked when I called. In a few moments, they reverted to the correct speed. I don't know why nobody else hadn't called them as they were the top station with the "beautiful music" instrumental format that was very popular at that time. They used to program music off huge tape reels back then. Your mono/stereo incident caused me to dredge this out of the old memory bank. smile.gif

Yes indeed....it was WDBN, not WDBM. A momentary glitch in the old system, I guess. Sorry. smile.gif

Has anyone heard faint "popping" sounds on channel 3? This has been going on for about a year and seems to come and go after local commercials are played. Most noticeable when someone is talking.

Same goes to 5.2, but with a bunch of "clicking" noises. Always thought it was the network feed until I heard it on a rebroadcast of News Channel 5.

Not sure if the above problems are present on cable/satellite services.

has anyone had any issues recording channel 19.1, CBS last few days? It seems when I tune to the channel in Windows Media Center, I get a fine picture. The minute I try to record I get a message "Service is Unavailable. No signal detected for this channel" Doesn't happen for any other channel. Only when I try to record it. Are they somehow blocking the over the air signal from being recorded?
post #3100 of 3985
I use Windows (Vista) Media Center OTA and have had no problems recording 19.1 or 19.2

One problem I did have was that the guide data some time ago changed the mapping of 19.1 to RF24 (the low-power translator in Akron rather than the main signal on RF10). Since I live in an area where 24 is very weak at best, I had to edit the XML file to point to RF10 (which is strong in my area). It's worked fine since then.

Turn to channel 5.2 now. The audio is clicking away like crazy!

Note: It's not my TV, it happens with every device with a DTV tuner in it.

Right now 5.2 is clear as a bell. No clicks or pops.Time 12:51 PM

Check out Channel 6, they added a bunch more to their slide show, including air staff and studio shots, as well more of Cleveland.
post #3104 of 3985
Just noticed that my TV says that channel 6 is broadcasting in mono. Does anyone else's TV say the same thing? The stereo indicator lights up on my radio.

FM stereo system uses a stereo pilot at 19 kHz and a double-sideband, suppressed carrier subcarrier at 38 kHz, which transmits the L-R signal, which in turn is matrixed (mixed) with the L+R main signal at the receiver, to produce left and right (the system has the same effect as switching the balance between left and right, and back to left, 19.000 times every second).

MTS (Multichannel Television Sound) uses a compandered L-R subchannel, but also has a pilot of 15.73426ish kHz and a subcarrier at 31.4685ish kHz, which is done to avoid interference between the picture and sound signals (the line rate of the picture is also 15.73426ish kHz).

You're hearing them in stereo on your radio because it is detecting their 19kHz pilot tone.
You are not hearing them in stereo on your TV because the station is not transmitting a 15.73426ish pilot tone - it's meant to be listened to on FM radios (as 87.9 FM), not really the TV sets.

This type of LPTV has been seen (or more accurately, heard) in many cities around the country. People have been using the term "Franken FM" to describe these stations.

Here is a new one
It appeared to me the OTA channel 8 had the english and spanish audio subchannels reversed.
On My TIVO premiere
Yesterday afternoon.

MeTV is off 19.2. A slide says "technical difficulties" (local slide at WOIO).

I'd assume it's Sandy related.

WEWS 5

Sunday Afternoon Movie (10/28/12) around 2-3pm - Haunted house themed with Yellow Lab Dog.

What was title? Guied on my converter box & TV just gave me WEWS 5 Afternoon Movie without title. Caught just a bit of it.

Could not view schedule due to flash content.

Noted this too, so we are kind of going back to the days when occasionally we would have a FM simulcast in the days before Stereo TV.

The Dog Who Saved Halloween ... I posted premature on this..

I'm also trying to find out an exact name of a movie that appeared on the CBS Saturday night novie (9pm to 11pm) in about 1971-1973 (probably 1972), was a British movie (I believe), that took place in the late 1800's or early 1900's, a dark green Craft was found buried undergrund either in a basement or a mine. The Craft obviously from Mars was inpenatrable. Title was something like somethng xxxx Million miles from earth (or miles from the sun)

It's "Five Million Years To Earth" (American title) or "Quatermass and the Pit ( British title) made in 1967 by Hammer Films.....one of my favorites of the older SF films! Much better than a lot of other stuff that was being released at that time, IMO. There's much information on this film and the other "Quatermass" films on Wikipedia. http://en.wikipedia.org/wiki/Quatermass_and_the_Pit_(film)

Believe that's it! (Thanks) .. I was about 8 or 9 at the time & this movie really held my attention. .. no wonder, $61- $124 on the Amazon for the DVD too.

Another Sci Fi Movie from that era I liked was Doppelgänger (Outside Europe, it is known as Journey to the Far Side of the Sun. .. & yes, I saw this one on Local TV too. smile.gif

Is anyone receiving 53.1 WCDN? It disappeared here sometime during Sandy's destructive winds.

So, basically you are saying that my TV is in fact receiving WLFM in stereo. But because the stereo pilot used in TV broadcasting isn't present, my TV displays the station as mono, or down-converts the audio to mono. So if they used the pilot tone on the TV side instead, the stereo light would not light up on the radio.

You are sort of correct, except that the TV does not "down convert the audio to mono". In both the FM stereo and MTS stereo systems the common factor is an analog mono FM modulated signal that tops off at 15 kHz. What makes the signal "stereo" is a difference signal (left minus right). That difference signal is modulated on a sub-carrier above 15 kHz. The radio sub-carrier is at 38 kHz, the TV is 31.4685... kHz. A Franken-FM signal is a TV audio carrier with a radio subchannel. If you watch ch 6 on an analog TV the TV cannot detect the 38 kHz sub-carrier as it's looking for the slightly lower 31 & change kHz sub-carrier.

I suppose that the Franken FM station could trick a stereo TV to light it's pilot light by inserting a second pilot at 15.73~ but it would not properly decode the FM stereo sub-carrier at 38 kHz. and it would adversely affect the sound on both radio and TV. Plus the FCC would not take kindly at any attempt. Since the effort here is to sneak another local FM station onto radios the TV signal is secondary.

I still get 53.1 just fine, no breaks and really solid but I never watch it however.

Hmmm.... Interesting, and you are only one town over.

I just checked the signal strength on my Zenith converter box. I am only getting 30% signal strength from WCDN, so it is there, but not strong enough to decode. Usually WCDN is receivable here with about a 70% signal. I doubt that it is my antenna since all the other locals are coming in fine.

I don’t watch WCDN either, but I keep it on the list because when it normally does disappear, that tells me the tropo is up. (Interference from Detroit’s WJBK – RF 7, same RF CH as WCDN)
post #3119 of 3985
Right now 53.1 is at 89 to 92 strength on my Sony LCD 46" XBR.

Just as matter of general interest for those who are Directv subscribers...I read on another forum that apparently Directv has just added the HD feeds of WUAB and WMFD to their Cleveland locals lineup. I think that makes them now carrying all major Cleveland market stations in HD. I tried to verify it late tonight but both channels had gone to infomercials. However they did appear to have better picture quality than the usual bad overcompressed SD.
