http://www.wmkvfm.org/ will broadcast a program today (5-1-09) at 4pm eastern called “The WLW Superpower Years”. Description:
Historic audio from programs broadcast on WLW-AM’s 500,000 transmitter in the 1930s will air during a one-hour special at 4 p.m. today on WMKV-FM (89.3), the noncommercial nostalgia station in Springdale.
“The WLW Superpower Years” also will include interview from those who worked at WLW-AM during the half-million-watt years of 1934 through 1943, says host Mike Martini.
The special marks the 75th anniversary of WLW-AM being the first and only U.S. station to broadcast on 500,000 watts starting May 2, 1934.
They have a stream link at the front page.

"We are the CC Borg. Lower your shields and surrender your broadcast stations. We will add your biological and creative distinctiveness to our own. Your broadcast personality will adapt to service us. Resistance is futile."
A question to the engineering folks: Is there something technically superior about those diamond shaped Blaw-Knox towers? I notice a number of clear channel heritage AM stations have them. Was it just a marketing gimmick? Was there any technicial or engineering superiority to using the diamond shaped tower over a traditional guyed stick? Why doesn't anyone use them anymore? Just really curious.
When using towers of about a half-wavelength or so the maximum current node will be at the center of the tower.
The fat center helps keep a low resistance in that area. The guy wires are there and are insulated from the tower.
The middle is a low voltage point on that type of tower. This type of tower would be very expensive to build today.
And nobody cares about AM broadcasting. The look of the tower is way cool. WSM has one of these that is slightly taller
and is visible from the interstate in Brentwood, TN. AM radio engineers are usually fat around the center also.

An engineer sits at the control console in front of WLW-AM's 500,000-watt transmitter in Mason in the 1930s.
Sadly, later, his children were born with purple hair, green noses, and four ears, and his brain was found to resemble Campbell's Chunky Baked Potato with Steak & Cheese soup.
"I don't know the same things you don't know."
"Yes, you do; you just won't admit it!"
"Yeeee...it looks like a 'Belt Buckle & Ball Cap' convention in here......"

Telling people that sort of thing is a good way to keep them away from the Marti antenna at ball games.
