I've noticed WLW going on and off (a few seconds at a time) this past weekend (a number of times on Saturday and Sunday). I assume they must be working on something. Anyone know why?

WLW Off and On
- Thread starter RATCISDJ94
- Start date
The question is: What's up with Clear Channel AMs?
55 KRC off last week. I thought their power seemed reduced later that day.
Then it was complaints about WHAS in Louisville.
So what are they installing?

The audio on the Reds' game was distorted, too. At first, I thought it was the encoding for Arbitron but it really sounded awful.
The reports are that the technology is saving real money at 50KW stations. That said, I know that WLW and WKRC have alternate full power transmitters (assuming they still are being maintained). Never been in WHAS' shack but one would assume they too would have a backup system. If they were installing MDCL, they should still be able to maintain full service while that was happening. Is this all just a coincidence? Or is the "out of sight, out of mind" mentality that owners often have regarding transmitter sites finally coming home to roost? If it's taken this long, it's a real testament to the reliability of today's equipment. Another angle...is the record heat this summer taking a toll?techie2 said:
Now if you'll excuse me, I need to go and clean/replace the air filters, calibrate the remote control, check the tuning and filament voltage, check the feed line pressure, confirm the modulation level and do a quarterly tower light inspection on a 3000 watt FM station in a town of 13,000 people where the owner has no shareholders to answer to and still cares enough to take care of his investment.

I agree with your view point of private verse Public corporate ownership.
Maybe they have a Harris 50...
Most of my buddies with a certain model of the 50 KW, Solid State box had problems. If the antenna match moved off of 50 ohms and modulation went a little too hot, the transmitter would do what i call "burp". It would take itself down and come back up in a matter of a second or so.
Annoying.
The Nautel, BE and even the Omni would just drop a couple of PA's (lowering forward power) and keep going.
I had one 50 KW that could handle up to 60 ohms AND 135% positive peak modulation. Almost like a tube box.

Had a call here at KSL-TV on a Sunday, a couple of years ago. An older lady (by the sound of her voice) said KSL was going "on and off". After figuring out that she was talking about RADIO, and she was listening on AM, I hunted down an AM receiver someplace. She was right!
The transmitter was running OK, but the exciter switch was going nutz-o, switching between two exciters. So, the meters looked OK, but the audio was cutting in and out.

Coulda been lightning strikes.
A few weeks ago I was listening to WSM one night in Chicago, and heard multiple little drop outs.
Very odd. When I got where I was goning, I checked the national radar and lightning strike map.
A big one had just cleared Nashville.
At 480 miles I couldn't hear any of the interference from the storms, but the effect of lightning droputs
is pretty hard to miss.

If we're talking 55KRC (where I worked in the mid 70's), that one is 5KW day, 1KW night. Commissioned a brand spankin' new pair of MW5A's in June of '75.greg.hahn said:
Randy Michaels worked at 55KRC and legend has it that he ran one of the MW5's into a dummy antenna at full power 24/7 overmodulated to the last drop. When something blew, he replaced it with the next bigger sized part. Did that for several months & then duplicated all the "upgrades" into the other MW5. Oh to have the resources to do stuff like that today. And yep Greg, it goes forever. That 1KW at night in Dayton runs circles around the 50KW on 1530. During the day, Michigan is an everyday occurrence for WKRC, even though the transmitter is in Kentucky. They say around Detroit, you aim the radio one way and get WKRC and the other way you get WGR/Buffalo.jry said:
I've never tried it (never have been to Detroit). IIRC, the person who told me that years ago had a GE Superadio I. I'll be interested in what you hear.
