KJL-88

Time moves on. It is only one of two constants in the world. The other being death. And that is certainly true in broadcasting. After the Digital Transition, it has amazed me at how fast the industry as a whole is moving away from analog. In less than a year, you walk into most any TV station in the country and you may not recognize it from this time last year. Widescreen news is just one of those things. Two years ago widescreen newscasts weren't on ANYONE's radar. Now, stations that don't have widescreen newscasts are going the way of the dinosaur faster than the Chicxulub meteor that wiped them out.

The past two weeks we have been upgrading our intercity microwave systems from analog to digital. It hit me that some of this equipment is the oldest in the whole station. Some of it was manufactured while I was still in junior high school! (As the kid on the add says, "That's oood!") The first question that hits me is why hasn't this stuff been changed out sooner! These are the links that bring back the video from the news scenes out in the community. The simple answer, Why? It works. It is bullet proof. It never fails. It is out of sight. It is out of mind. And there are literally TENS OF THOUSANDS of these transmitters and receivers slaving away all over the country. And have been for decades!

Starting in 2008, due to a rule change by the FCC, and the money of Sprint/NEXTEL who wanted to carve out a piece of the broadcast mobile microwave band for commercial use, all broadcast mobile microwave transmitters and receivers nationwide had to be changed out. In order to fit the new band, it had to be digital. The Piedmont Triad was one of the first areas to convert. So from the trucks to the microwave receive sites it has been digital since 2008. But from the receive sites back to the studio, it has remained analog. And the pictures provided it. Hence, the change out.

But one link holds a special place in my heart. And that is KJL-88. If you saw the changeover from analog to digital last June, after the Star Spangled Banner played, you saw a "slide" of an old WGHP ID logo sign off. On it, in the lower third, KJL-88. It is on YouTube. Check it out!

You may be asking, "What is a KJL-88?" KJL-88 is the call sign assigned by the FCC for a specific fixed microwave link. It just happens to be the first microwave link assigned to WGHP back when it came on the air in 1963. (We now have over 10 fix point microwave links running all over the Triad to bring back live pictures of news events.) If you ever watched WGHP from October 14, 1963 to March 31, 2006, you were watching KJL-88! It was the main, and at the time only, studio to transmitter link. That is how the programming got from first the Old Sheraton Hotel studios and then later the current Francis St studios. After the new transmitter site went on the air in March 2006, KJL-88 was reclassified as the backup microwave link since the original tower (which we now call the "Plainfield Transmitter Site") became the stand by tower site. (SIDEBAR, WGHP is the only TV station in the Triad that has two completely separate and independent transmitting sites so if thereWGHP Auxiliary Transmitter Site - 1999 is a major problem at one site, the other site can come up and we can continue to broadcast.) For the next 3 years, KJL-88 continued to operate as it had for the preceding 43 years, just no one was watching since the backup transmitter was not turned on except for testing into the dummy antenna. After the June 12th 2009 transition to digital television, it looked like KJL-88 may have broadcast it last. The analog equipment was not compatible with digital broadcasts and the equipment itself was over 30 years old. We had placed a digital receiver that was on the main microwave link to the new tower site (which is call the Courthouse Site) at the Plainfield Site to keep the channel 8 digital backup transmitter serviced, but that wasn't a permanent solution. You see the Plainfield Site is also the location of one of our microwave receive sites so we have to be able to send video from the trucks back to High Point from there. When the return link was put in back in the late 70's, early 80's, it too was analog. In order to continue to keep communications with that receive equipment, we had used some of KJL-88 to send the controlling signals over it. How to do it now? The microwave link back TO High Point (WLD-423) was staying. What about the link FROM High Point (KJL-88)?

The old analog equipment for KJL-88 was removed last year and it was traded in for other microwave equipment we needed on other microwave links. So for the first time since 1963, that link was open. We maintained the license (good ole' KJL-88) but what to do with it now? It is interesting to note that the equipment removed from KJL-88 last year was not the original equipment. Even though the equipment removed was installed in 1976, it replaced the original KJL-88 equipment (version 1.0) from when WGHP went on the air in 1963. That equipment was a RCA tube type microwave system. It had no backups that I have ever heard of. One story of interest was the receiver. There was one tube that would go out on a fairly regular basis. Since the transmitter site was manned in those days when the transmitter was on the air, if the tube went bad, there was a case of tubes sitting close by. As the signal started to fade into snow, which viewers at home could see just as easily as the engineers could, the duty engineer would pull the offending tube out and plug a new one in. But these tubes were famous for not always working straight out of the box. I am told it was not uncommon to try 5 or 6 tubes before one was found to work. Of course while all this was going on, there was no picture on the air. Just black or a trouble slide on air generated at the transmitter site. Remember, it would take 30 to 60 seconds per tube to see if it would work so this process could last 5 minutes or more! The station suffered through this until KJL-88 version 2.0 was installed in 1976, with the solid state equipment I pulled out of service last year.

Earlier this year it was decided that there would indeed be a KJL-88 version 3.0 and it would be digital. It would feed the new channel 35 backup transmitter at the Plainfield Site and continue to provide control signals for the receive site. And since we were upgrading this link, what about the return path back to the studio (WLD-423)? It was decided to make that link digital as well. And I guess while we were on the subject of microwave paths, what about the others. Obviously, the main microwave link to Courthouse Site was already digital so we didn't have to worry about that one. Pleadings and beggings were performed. Arms were twisted. Compromising pictures taken. Deals cut. Money extorted. In the end, it was decided that while we had the attention of the microwave companies (who were begging us to buy and willing to give first borns if we did) let's upgrade the other paths as well and clean up our microwave shots that would then be digital from the field all the way to the viewers TVs. Equipment was ordered and after waiting what seemed an eternity, it began arriving several weeks ago. First link to be installed? KJL-88 and its return link sister WLD-423. Since then, we have installed the link from Greensboro back to High Point and next on the list, the link from Winston-Salem to High Point and the link from our news bureau at the Winston-Salem Journal. As sweet as it is to have those links converted to digital and the improved pictures from the field that viewers can see now, to be able to fire back up KJL-88 after almost a full year of being dark, was a great feeling. A connection to those engineers of yesteryear who first put KJL-88 on the air in 1963. The link I remember watching as a kid. A year ago, I didn't know if KJL-88 would ever live again. Today, it will live for the next 30 years at least.

So if you are awake around 3 or 4 AM, that is when we run the ID graphics of the microwave links and you will see KJL-88 on it. And that's the story of KJL-88.
