WTCM-FM back to #1 (just ahead of KLT and Big Country) despite the new market definitions eliminating two of TCM's strongest counties.

Impressive that WTCM-AM gets nearly a 5 share despite being an AM only station!

50000 watts at 580 kHz, with a Directional Antenna which blasts the counties in the Market. The maximum Standard Pattern IDF at 35 degrees is 5435.53 mV/m at one kilometer, which, referred to the standard efficiency in the International Agreements, 300 mV/m @ 1 kW @ 1 km, is 328000 watts "ERP", though ERP is not defined in any other way for AM by the FCC. This, despite the fact that the conductivity is much less than M-3, measured by their own DA proofs of performance, blankets the most populated Northwest Michigan Counties, with a City Grade measured signal of 5 mV/m. The only thing that might help, especially at Night when the power drops to 1100 watts, is a translator within the 2 mV/m contour in the outer edges of the service area.

Since radio stations never use their call letters other than at the top of the hour, it's amazing how many of these stations I cannot identify. Now, if they were listed by 'The Fox," "The Bear," "The Orangutan," "The Gourd," "Happy Hunter 104.5," or "Q-Licious 101," I might know some of them.

WTCM always states they're legal ID call letters at the top of the hour. I would presume the other stations also do that as it is required by the FCC, but there is always one that lets it slide out there.
