Senior Road tower IBOC project questions

M

Mediafrog

Guest
Some weeks ago, a poster (can't remember who) mentioned that during June and July the Senior Road tower (home to nine Houston FM's) would be undergoing conversion to IBOC, and that all the FM's using that facility would have to switch over to their auxiliary facilities for several weeks.

Any updates on what's going on and when? And what is involved? New combiner, transmission line(s)? Modification or replacement of the current master antenna? New transmitters? Details please!
 
The project is a little behind schedule. The work will not start until late July.
It will require that all 9 stations leave the master antenna for several weeks. The old master antenna will be dismounted and a new analog/digital antenna will be placed atop the tower. The combiner will be replaced and everybody should/will have a new IBOC transmitter in their room for the 10 to 16 radios that are in use ready to receive the IBOC signal.

Do any of you know where the auxiliary locations are for each FM station?
 
The 9 stations will be transmitting ( at various heights) from some of the other towers out in the Mo City farm.

Going through the FCC database and deleting any auxiliary facilities that are on the master antenna, this is what I came up with. I really don't understand a station have their auxiliary antenna on the same tower as the main antenna. In this day of terrorism, if the tower(s) were blown up it would take the station off the air along with their backup. Actually the backup towers are not spread out as much as they should be around the city. Unfortunately Houston is a very good target for terrorists and disrupting communications would be a priority. NYC is installing backup transmitters at various locations around the metro area so they aren't knocked off the air like last time on the FM band. Enough preaching, just pray it never happens here.

Many of these are listed as Construction Permits, but the towers exist, so it is just a matter of installing the hardware and transmitter. Many of these stations are likely ready to go on the air and don't have a license yet.

The majority are going to a tower in the 2800 Block of FM 2234 Mc Hard Road, Missouri City, coordinates: 29-36-16N 95-30-38W the actual tower is 601.3 meters tall.

Thats the Richland tower..(just south of the Sr Road tower)..they are building a new FM xmtr bldg at it...I thought they were putting a panel master antenna up..

That is the American Tower (the one at the southwestern end of the antenna farm)Also has UPN TV/DT, Channel 55 is building there, Channel 61 and 44DTV just moved there and one other TV xmtr....

I think that is Shell Plaza...but that antenna is SHOT up there...it cannot hold gas and the stations take a chance every time they use it

They are gone from that site...have been for a while....
KHCB's aux site is still there though (nice 10KW solid state Continental)

Yes MIX has had their aux there for a long time (I understand that Liberman is actually looking for land to move 1230 to its own REAL tower...the folded monopole job they have been using sucks!)....to the north it can cover up Sr Road if both xmtrs are on (which has happened only once I know of ;)
 
No broadcasting from Williams Tower?

Such a nice perch up there and no transmitters? Would the WT owners allow it?
Just curious :)<P ID="signature">______________
I listen to what I like.
Ratings be Damned.</P>

Nope...rcv site for a lot of RPUs (remote pickup) and some two way repeaters but no room for a broadcast antenna.

CW could well be that they are installing a panel master antenna and the Mod CP will show up, possibly after the fact. It doesn't seem unusual and the FCC doesn't seem to get very concerned about the fact, as long as it is with-in the licensed parameters a station has in coverage, in this case the coverage from the master antenna.

There must be a 100 different transmitters or receivers on top of Shell Plaza. I am kind of surprised since Shell isn't nearly as tall as many buildings around them and this would degrade the signal. I would expect what was The Texas Commerce Tower, I know that isn't the name any more, but don't know the name of the building now, would have the "antenna farm" on top of that building as it is slightly over 1000 feet and the tallest building downtown.

CW do KODA, KILT, KTBZ-FM even use the Shell Tower facility? It doesn't sound like much of a backup.

This is may be an unanswerable question. Since KHJZ has been gone from The San Felipe Plaza site for some time and KQUE 1230 sync site out near Little York-The Beltway-Northwest Frwy hasn't been used for years, why do these show up in the FCC database? FCC just missed getting them deleted or the stations didn't report that they are no longer using those sites?

Also why are "allocations" for AM showing up, like 1210 for Bay City, which has been in the database for probably ten years? I'm not aware of any cities being allocated frequencies on AM the way it is done on FM.

LBI is investing a large amount of money on towers in the Houston area. Surprising for a company that is so tight with their money. I have to admit it is a little confusing, especially since the LBI stations aren't doing very well in the ratings. It would be nice to have 1230 cover more than just inside The Loop and if the antenna is built to the best specs, as the FM stations are, 1230 might have a decent coverage of the city. It would be great if he would upgrade 700 and 880 to higher powers, 700 at night and 880 day and night and cover Houston with usable signals 24/7, while the opportunity still exists. A new tower for 1230 is the best that can be done on that frequency. If KXXT 700 Wylie-Dallas makes it on the air they will add some interference to 700, not that it will be noticeable with WLW. I expect south of the boarder interference on 700 any time now. Actually I am surprised that KSEV has gone this long without interference from south of the boarder or Cuba, it can't last much longer. Jamaica used to show up every once in a while.

At one time, the Shell Bldg was the tallest building in Houston, thus the reason for the now empty antenna. That was in the 1970's. As far as broadcasting stations is concerned, it has been empty for some time, now. In 2001, at KILT, I went on the Shell Antenna, while some work was being done at Senior Rd. That was the last time, I used it. Four months ago, I was told about some sort of overhaul on the existing Senior road tower. The McHard will be the back-up.
