[IRCA] WXYG vs. KWMT vs. CBK vs. XEWA

[Rick Dau <drummer1965usa@xxxxxxxxx>]

I hadn't even known that WXYG wasn't on the air yet until I opened up my inbox 
this morning and saw Paul Walker's original post on 'em. 


Some thoughts: I have no idea how the FCC even let a station in mid-Minnesota 
on 540 in the first place, when KWMT and CBK are so near and stations on 540 get 
out like gangbusters.  And I especially can't see how WXYG is able to throw 
virtually all of its night power in the direction of Fort Dodge, when they 
SHOULD be protecting KWMT at night. 

  
Regarding XEWA, I haven't heard them ONCE since starting a new logbook at my 
South Omaha QTH this past September.  At night it's CBK when the Quantum loop is 
pointed NW-SE and KWMT when it's 90 degrees from that.   


KWMT gets out amazingly well to the south -- Glenn Hauser sez he hears them 
daytimes 365 days a year in northern Oklahoma.  But, to the north, it's a 
totally different story.  When I drove to Winnipeg in August 2008, KWMT was 
still there, albeit not real strong, in Redwood Falls, Minnesota.  By the time I 
got to Fargo, however, it was all CBK. 


Once upon a time (say, early 1960s and before), KWMT held the honor of having 
the largest daytime coverage of any AM station in the U.S.  Nowadays, I'd put 
them 3rd behind both KFYR-550 (whose terrestrial signal I was listening to 
through most of this morning for their coverage on the flooding in Minot) and 
WNAX-570. 


And CBK easily gets the honor of largest dayime coverage of any AM station in 
North America.

That nighttime pattern surprises me, but I forgot Fort Dodge isn't entitled to 
nighttime protection. Ouch, that's got to be quite a clash in KWMT's secondary 
coverage areas (Storm Lake, Ames), especially since they ALSO null to the north.
