There's no need to guess about what it will be. It's all set out very 
clearly in the application.

Here's their coverage map:

And a shorter link:

Look at exhibit 12-1 to see what the Yelm daytime coverage will look 
like. Even the daytime 5 mV/m contour falls short of Olympia and Tacoma, 
and it actually has a null toward Seattle as a result of the protection 
it has to provide to CKWX and to Whidbey Island on 1110. It's not aimed 
north - it's a figure 8 with lobes WNW and ESE and nulls N and S.

Exhibit 12-2 shows where the fringe (0.5 mV/m) daytime coverage will be. 
 This thing won't be even close to listenable anywhere in King County, 
and will be rough even in Tacoma.

At night, the only really usable coverage will be in Yelm and North 
Yelm. That's not to say it won't be DX'able from elsewhere, but for your 
average AM listener in Olympia or Tacoma, Yelm 1120 will simply go away 
at sunset, replaced by KPNW.

And to clarify the way the rules work: KPNW doesn't have to do anything 
to protect the new Yelm signal. KPNW was there first, and Yelm has to 
squeeze its way in around the existing KPNW signal.

This all assumes that this signal even gets built; the weakening of the 
economy has shaken out a lot of marginal signals that might have been 
worth building a decade ago, but aren't worth it now.

If I held this CP, I don't think I could justify building it. A 
three-tower DA doesn't come cheap, and I don't think there's enough 
business in Yelm to make this worthwhile as a hyper-local station...or 
enough usable coverage even in Olympia to make it viable there.
