HUM IN WPTF

OK, I already brought this up in a previous post. But the fact is this. There is a ground loop hum in the Rush Limbaugh feed that is not present at all in the 640 AM station from Fayetteville's Limbaugh feed. It's been there for at least months, maybe longer. As much as I despise the show, I still find it annoying that a big 50,000 watt station is as careless as WPTF is, and allows such technically crappy source out on the air. Maybe nobody at the station listens to Limbaugh, wouldn't blame them. No dittos here.
 
I know what you mean...I heard the same "hum" when I was
in the capital city a week ago. Maybe the guy whose looking
for that engineering job at CMG will be the one to "de hum"
it!

Might not be on radar screen

Maybe this problem falls last in a large punch list of things to do, so it doesn't even make the radar screen. I once spent 2 full days chasing a hum in a production studio. What made it difficult was all the gear that a studio has. I did find it and kill it but it damn near killed me...LOL
Or maybe the hum is placed there by the government to reprogram liberals.....hmmmmmmm

Another tedious negative post from radio-outsider. He only has something to say if it is negative. If you do not like the Rush Limbaugh Show you do not have to listen to it. Therefore, the hum should not bother you because you are not listening to it. I find it disturbing that crusading aginst this so called hum has become your passion in life. Find something else to gripe about Mr. Negative. If you don't like Rush don't listen and those who like him will keep on listening regardless of your rants.

I was an engineer at WPTF for two years and then chief engineer there my last year at CMG in 2000. I can't speak for the situation now but here's a little info from a few years ago.
Like you said, the engineering staff was swamped. We had fifteen stations at that time spread between Burlington and Goldsboro and the satellite network (Southern Farm Network) and only three engineers. We also had to often help the older guy who did remotes. There was always some crisis coming up (small fire in the console at one station, flood at another, lighting hit at another, car hit the guy wires at another and fold the tower over) and I did often chase hum issues at Highwoods. It makes it difficult since there have been probably 15 engineers through there since the facility was built in 1987, many with their own ways of doing wiring and many people not labelling things. I went through when I was there and pulled out a lot of old unnecessary wiring and tried to make sure that everything was labelled and documented.
A lot of the equipment there has basically been on continuously since 1987 (except for brief power outages) so I suspect that some of the electrolytic capacitors are getting dried out and leaky. Also there were some weird limiters and an equalizer in the signal chain that we didn't know why they were there but the DOE said to leave them since they were not broken.
The building has a whole building UPS that powers all the radio station studios upstairs(special outlets under the consoles and in the furniture) and the two TV stations downstairs. So I think that there have been a few instances where someone doesn't realize this and plugs a piece of audio gear into a non ups outlet and that can cause problems. Some of the molex connectors on the back of WPTF's PR&E BMX console may be loose if they haven't been checked in a while. We had a couple loose on us and it caused the audition bus to have a loud hum. This one was fixed immediately.
When we converted the old WQDR news studio into the studios for WCLY (that studio was gutted and rebuilt for Y102.9 when 102.9 moved over from west Raleigh right after I left) There was one heck of a hum problem due to some power issues in that studio. Plus we were installing a Dynamax console which didn't help matters!
When I built the 96 Rock studio I got to start from scratch and do everything right with completely new wiring and new equipment. That's the way to go!

What processor(s) does WBBB use? Omnia 6? If not it should. And they need to squash it! Last I knew WRDU ran an Omnia HOT. Not as good as the 6, but it sounds pretty good.

WBBB uses the CBS Volumax. Much better than that crappy Sears Kenmore 405 they used to have.

Re: Hum on WPTF

Chris,

I invite you to stop by Highwoods one of these days to take at some of the changes since you left. Give me a call and I’ll be happy to show you around. There’s still room for improvement, but we have a completely upgraded network infrastructure with high quality managed switches, VLANS, home-run network cables throughout the building and a network device (FatPipe) that aggregates the bandwidth of three ISPs. Processing for WQDR and WBBB was upgraded to 8400 Optimods a couple of years ago. That was the PD’s choice—they could have had Omnias if they wanted. PTF is using an Omnia AM 4.5. New digital audio hardware and software for WPTF, WQDR, WBBB, WWMY and WYMY was installed two years ago. WQDR’s control room has been upgraded with a new console and completely rewired—by engineers who know how to do it right. Email me and I’ll send you some pics. In the four years since I’ve been here, new transmitters have gone in for a station or two every year. This coming week we’ll be installing a new STAC12 phone hybrid for WPTF, receiving a new 500-foot tower in Goldsboro and setting up an ISDN box in Allan Handleman’s home studio in Charlotte, among many other things. It’s STILL of lot to keep up with—16 radio stations, a traffic network, a farm network and a new Internet-based project, “State Government Radio.” Yes, the Limbaugh hum is on a punch list and I’m embarrassed it’s dragged on so long. But the equipment to fix it is in house and is scheduled to be installed in the next day or so. The point is CMG IS a good place to be these days—for people in all departments including engineering. Our day to day operations are led by one of best radio managers in the country, Phil Zachary. QDR is the top rated and top billing station in the market. The Raleigh cluster is the top billing cluster in the Triangle. We are locally owned and do not answer to Wall Street. Any “Po Broke Engineers” who are interested in joining the team should contact me directly.

I may be critical, but I'm a rank amateur compared to Limbaugh. What bothers me is that under deregulation, technical standards continue to be compromised, and that good engineering has become a low priority in the industry.

If you read further down, you'll notice that my rant has gotten the attention of the Curtis engineering staff. Maybe having documented complaints from listeners will help them convince management that they need additional staff and funding.

Remember: "Progress is usually initiated by discontent."

Amen. Somewhere along the way, the big shots confused technology with "maintenance-free" and so now, in a lot of places where you used to have a full-time chief engineer, there's now a part-time guy with no benefits while carrying almost the same workload, or some other guy who lost his full-time jobs years ago, now doing contract work and running his arse off statewide to care for several different stations in order to put bread on the table. Or heck, it may be worse than that. I don't think anyone in the radio business got the shaft worse than the engineering folks.

Difficult to say... Contract engineers have always seemed to enjoy a rather decent wage. I know there are shops that have pretty much eliminated engineers, and then there are shops that are 100% staffed by sales and engineers. I don't know of any that can do completely without an engineer, and none that can do without sales staff, but quite a few stations are making do without any air talent. Which gives us lovely moments such as the Russ Par producer saying live on the air on a station in Louisiana, "Ray Jay, your promo feed comes up in 10 minutes!" And he was actually talking to a station in South Carolina.
