First Daytime-Only AM Station

T

trusty

What was the very first daytime-only AM station in the U.S., and does it still exist today (with or without flea power at night)?
(Is there a list of daytime-only stations?)

Thanx.
 
WDZ 1050 Tuscola (Decatur, Ill.) was a daytimer from the time the new FRC came up with the idea in 1928 until the 1980s, when a treaty allowed night operation.
 
A bit off topic (sorry, but your "flea power" comment reminded me of this). The first station I worked at in the early 90s was an independent AM/FM, and the AM had been around since the 1950s. When I first started there, they were running a very old GE 1,000 watt transmitter with 4 tubes visible through the front viewing window and they'd play a sign off cart, shut the thing down and just go off the air at midnight. A few months later they decided they wanted to stay on the air 24/7, so they bought a tiny (especially by comparison) solid state 30 watt transmitter that was mounted on the wall next to that big GE. At midnight you'd switch off the GE, turn on the solid state and leave. They were just airing CNN Headline News overnight so it ran unattended, and the FM jocks who worked overnight (remember those, even in a small market like I worked in??) logged readings.

Flea power at its finest!

I did not check the history, but I believe WHA in Madison also dates back to that time as a daytimer.

WDZ negotiated a treaty with the FRC?

A treaty/agreement which the poster referred to ended up changine the night protection requirements on certain clear channels in the late part of the 20th Century. I believe it was the implementation between the FCC and Mexican regulators that resulted in the changes under the "Mixed Committee" ("Comisión Mixta") or whatever the translation to English is.

Search on "Comision mixta" +FCC and you will get a lot of references.

WOI Ames IA on 640 was a former daytimer that probably dated back to the 1920s like WHA and WDZ but there's a server error tonight on the FCC site to access the history cards.
 
I noticed a few daytimers from the earliest Broadcasting, including WAAF in Chicago. So I checked some history and found this sentence from Chicago Radio History:
"In 1924 the Chicago Tribune acquired WAAF and changed the call letters to WGN."
which doesn't seem to be correct (WAAF and WDAP/WGN histories don't mention this.).

Anyway, since daytimers are found in the 1920's, they overlap with shared time stations (833kc). So, when the band was expanded, did daytimers have a restriction on their licenses to protect clears?
