Just wondering if anyone else has noticed the distinctive "wheen" this station has in its audio??

The format is good!! in fact its my number one preset. The signal is good too as it passes the great Camp Nelson Hill phenomenon that so many others get rather static filled.
The 96.9 problem was in new Harris 30K transmitter. Lots of power fluctuations at the site and the tolerance window is quite small. Good ole Pete Boyce figured out a way around it. Bought it new in 2010 and it's had a major problem about once a quarter.
Now, what the frack is a "wheen"?

I think a wheen is probably a whine.
I've installed two of those Harris HPX transmitters- one in Feb 2010 at WHKO in Dayton, and the other in Dec 2011 at WVEZ in Louisville. Neither one of them have had any trouble. (Except a minor issue with the diagnostic display at WVEZ.)
My company has those all over the country.
Are you sure you don't have an installation problem?
Greg, Dan Carcopo from Harris did the installation and he's a competent guy. The problems have been component failures incuding the exciter, low voltage power supply (twice) and the plate transfomer. Maybe we just got a lemon.
JB, thanks for the tip on the "wheen". After 45 years of headphones, I'm lucky to hear anything and don't hear it. We'll run the analyzer and try to find it.

Might that "glitch" be described as a stutter? Like the audio pauses for a split second and then continues?
If yes, my question is whether B92 is running NexGen from one of the servers from the old Blue Chip stations that Lynn bought out years ago?

30K? Isn't it a 50k station?
FMs are computed by ERP- "Effective Radiated Power".
ERP = (Transmitter output power - line loss) times antenna gain.
So, for instance-
26,100 watts out of the transmitter, with 2600 watts lost in the transmission line = 23500 watts makes it to the antenna.
A 4 bay antenna might have a gain of 2.13.
23,500 times 2.13 = 50,055 watts
All FM stations work this way, though the numbers vary widely.

Carcopo and Chris Aquinas (sp?) are both excellent.
And you seemed to be very unlucky. They did have to put in a beefier power transformer than the original, and beefier low voltage supplies and feed through capacitors. I got free retrofits of all that stuff before anything failed. But to think that you were affected by all of those issues makes me think someone there shouldn't buy any lottery tickets.
Especially with also losing the HDX exciter.

Interesting.
Left Lexington in early 2001 so I can only listen online but the glitch or stutter I'm hearing online today sounds the same as what we fought a dozen years ago at the Blue Chip Oldies 96.1. As I recall, the first thought was buffering. Didn't solve it. Voicetracking seemed to exacerbate the stutter. We could lessen the recurrence of the stutter by a daily reboot of the server. My time with Blue Chip ended before the lead tech at NexGen could find a solution. I vaguely recall the last idea I heard tossed around involved audio levels and a conflict with the file type of the source material for the music library. I'd drive through Lex and I was still hearing the problem on Oldies up until the change to Super Talk. I'm guessing Marconi Jr. could answer whether or not that old Oldies 96.1 server might somehow have ended up in the B92 studio after the move to Victorian Square. Never had the same problem with "The Beat."
That server on 96.1 was a P3 with about 250 megs of ram. It was actually ok during the talk format as it only had to play the smaller commercial files. The problem with stuttering hit hard when we went to classic country, so I replaced it. All Nexgen servers and control room machines have all been replaced over the last 4 years. One at a time since I'm an army of one. lol
We didn't see anything on the analyzer so thanks for the stuttering clarification. We had that problem a couple of months ago and I thought it was fixed by a cpu replacement. Hmmm. Let me know when you hear it again please.
