WMDN was 5 towers inline days and six towers in a 2 by 3 nights, from 
Toledo, using two separate sites, one north of Toledo and one south of 
Toledo. The night sight has been abandoned after several STAs.

This is a COL move, and also a change to a combined site with 5 towers 
inline days and nights.

This station was only feasible because the co-channel Class A in Buffalo, 
located 250 miles distant, and nearly due east, across almost the entire 
width of Lake Erie, operates DA-1.

If the Buffalo Class A was to have operated DA-N, there would likely be 
no possibility of day operation from Toledo, and night-only operation is 
not permitted if there is no day operation.

I believe this is the closest-spaced Class B to a co-channel Class A, 
anywhere.


WDMN previously operated licensed to Toledo with 1 kilowatt day using a six 
tower parallelogram array located in Temperance, Michigan and 1 kilowatt at 
night using a separate six tower in-line array located to the south of Toledo, 
near Perrysburg, Ohio.  The nighttime array had not been operated for at least 
ten or fifteen years, however, and the station had been operating effectively 
as a daytimer under an STA.  The previous move of WDEO - Ypsilanti, Michigan 
from 1520 kHz to 990 kHz made possible the consolidation of both modes of 
operation for WDMN at a single site.  Because the 1992 modifications to the AM 
protection rules no longer made it possible to provide nighttime interference free 
coverage to at least 80% of Toledo, as required by Section 73.24(i) of the FCC 
Rules, it was necessary to change the station's community of license to the 
Toledo suburb of Rossford to implement this site consolidation.  Because of the 
tall towers in the recently licensed new five tower array at the consoldiated 
site, the radiation efficiency and coverage at the reduced power levels is at 
least that which was provided by the previously licensed 1 kilowatt operating 
facilities, both day and night.  Except for different pattern augmentations 
and a reduction of power at night, the day and night patterns are identical.

There are actually two daytime only Class B stations on 1520 kHz in Ohio 
(Kent and Canton, located only 32 miles apart) which are located significantly 
closer to Buffalo.  There is also a 1520 kHz nondirectional daytimer located in 
Bryan, Ohio, only 30 to 40 miles to the west of Toledo.  1520 is really a 
screwed up channel in Ohio.
