Partial daytime AM Band Scan during power outage in Tawas City

The technical side of broadcasting. Think IBOC is a sham? Talk about it here! How about HDTV? Post DX reports here as well.

This CKLW coverage map does not correspond very well with the Radio Locator one. In some directions, it corresponds more to the 0.5 mV/m (center) contour, and in others it corresponds to the 0.1 mV/m (0.15 is the outer contour on R-L). This is quite apparent in the direction where the null toward Grand Rapids is. It seems to be much shallower than the R-L Map. Too bad Ed Buterbaugh isn't around to ask if and when the pattern changed. I wonder it if was when they broadbanded the towers in anticipation of going AM Stereo.

The tower arrangement and original pattern were reportedly designed by the late Carl E. Smith, and is quite a a versatile arrangement to change to very different patterns. The original DA was from 1947-1949 from application to licensing. The four tower outer parallelogram arrangement is the same as WTAC 600 (now WSNL from a new TL and very different pattern), designed in 1946, without the center tower, and rotated about 27 degrees clockwise. It was also apparently designed by Carl E. Smith.

In another historical perspective, the date on the QSL Card signed by Ed is from the night before "The Day The Music Died" when WCFL went from Top 40 to Beautiful Music on March 15, 1976.

For the biggest part of my life I lived up in the area I have indicated with a red dot. CKLW pounds in there like a local, day and night.

I remember J.P. McCarthy and John McMurray talking about Tobermory and stopping off in Tobermory Harbor with their boats. They talked about listening to WJR there, and beyond.

Yes, WJR is a blowtorch up there too. I have fond memories of Tobermory. Haven't been there in at least a decade. That will be a nice trip to take whenever this disease is rid of.

WJR 760 0.5 mV/m and 0.1 mV/m contours. Years ago, one of the old-timer engineers told me he had done some measured field intensities for this map.

Thanks for the info on CKLW.
I spent my summers growing up near Belle River.
Always thought that the tower on the river was the 800AM transmitter tower.
Drove past that at least a dozen times every year.
Guess I was wrong all these years.


I got thrown out of sexual awareness training.
I raised my hand and asked "Harass. One word or two?"

Is that Belle River ON?

During my career I did business around that community.

When I worked in Niles, MI, I would get CFCO in stereo in the morning in Three Rivers. Shortly west of there, they would drop out. At that point, I would switch over to WGTO 910 (Cassopolis) and listen to oldies in stereo.

Does the AM station on the last dial in Tawas City still plays former game show host Wink Martindale's 30's to early 60's music?? Did that station doesn't serve beautiful music anymore??
