55KRC Signal - Being "DUN-in" at Dusk

H

hipporadio

Upon a trip home this past week to celebrate my father’s 75th birthday; I noticed very severe interference to 55KRC’s nighttime signal just northwest of Cincy over in Indiana. KRC’s signal there is usually very good [it actually improves with their change to the night pattern despite the power reduction to 1kw due to the reduced daytime limit toward 560 WIND Chicago]. Every night this past week, they began receiving co-channel interference from one strong signal around 9:15PM EDT... By 9:30PM, the offending signal manages to nearly equal KRC’s to the point that the two carriers actually “beat”.

I first thought it to be KTRS St. Louis since they had been on a non-directional STA at about 1kw due to a fallen tower last summer. KRC had received some intrusion from this arrangement, but I hadn’t noticed it this past spring and wondered if KTRS could still be on that STA a full year after the freak weather incident that took out one of their towers.

Tonight [Friday evening], the interference is so severe that a clear ID copy [and baseball coverage] was very easy to hear. It is WDUN Gainesville, FL. Interesting that they managed to recently jump to 10kw ND day, but maintain a highly-directional 2.5kw signal with the only lobe aimed near due-south [at 190-degrees]. There is nearly no energy allowed to radiate toward Cincinnati. How could such a parameter [properly followed] allow for interference this severe? On the 10kw ND day facility, maybe? Possibly, the CCU techs should investigate... Hey KRC folks – you’re un-listenable in Franklin County, Indiana near Brookville Lake!
 
Yet here in Atlanta, where we get WDUN just fine during the day, there's no trace of it after dark. Surprisingly, I catch KTRS on 550 most nights in Atlanta.

Wrong Gainesville. WDUN is in Gainesville, Georgia...

OOPS! Thanks L.F.V. for correcting my typing fingers, which were moving quicker than my ageing mind [Brain-Belch] ::) I guess it’s easy to associate “Gainesville” with the Sunshine State.

KRC’s nighttime signal is consistently-excellent to the northwest of Cincy out as far as 50-miles. With the exception of KTRS [when it was on its emergency STA] and an occasional Oldies station [so far under that an ID copy isn’t possible], KRC reception is very clean at that location. I began scratching my head when I heard the WDUN signal several nights in a row, and its overwhelming level would give cause to wonder. Interestingly, it was absent at 5AM this morning.

Is this a case of “Mother Nature having a tantrum”? Any observations or ideas?
 
I've found a good tactic to deal with such "laxness" is to send them a reception report telling them how juch you enjoy listening to them right after sunset hundreds of miles away. Ask them if they just signed on recently, etc. Phone calls to manned stations work even better. It worked great on 1310 in Indy is 1978 about 2 hours after sunset & it workled a few years ago on 820 near Tampa. That 50KW day signal roars into Indiana at night...at least it did until 45 seconds after I got off the phone with the announcer...oops.
 
Something like this happened in the Bay Area. KGO-810 had problems with a 50 kw daytimer from Washington state blasting into San Fran. after sunset. KGO contacted the daytimer and threatened to turn the other station in to the FCC. The daytimer got the message.

E-mail or phone the CE at WKRC about WDUN blasting in after your local sunset. He'll do the same thing.
 
Up here in Richmond IN we can't get 55 krc anymore. 700 wlw comes in just fine.
 
I noticed that 55krc was on reduced power a couple of weeks ago during the day maybe for tower work perhaps? Maybe that is why the night signal is being reduced. Who knows?
 
So... It’s about 9:30PM Saturday, and NOT A HINT of WDUN on 550! Hummm... Wonder who reads these R-I ramblings?

'Hardly an ounce of RFI behind WKRC. The good Doctor Ruben's Omega-3 fish-oil infomercial is clear as a bell... Darn—where's WDUN when you really need them :D
