Not an expert on towers--only the effects of non-comm saturation. Nonetheles, I can answer your question, as we had a similar (hell, damn near identical) situation at WXJX...

Pitt's Towerless Signal is nice!
WPTS is a non-comm situated in the commercial band at 92.1 MHz, with approx. 13 watts of power (give or take).
As such, it is not protected in that position, that is, if another commercial operator wanted the 92.1 position, WPTS would be kicked out--and NOT guaranteed a spot in the dial, either non-comm or comm. My suspicion is that WPTS is an old Class D non-comm that wouldn't increase its power in the late 70s/early 80s.
Then-WJCR at Washington & Jefferson College encountered the same thing: we had a Class D (no more than 10 watts ERP) at 88.3; the Trustees refused to authorize the $8,000 for a 100 watt transmitter to stay in the non-comm band (1979). As a result of the FCC decision to get rid of Class D's (both comm and non-comm), WJCR was forced to move to 92.1, in the comm band without protection.
We stayed there, as WJCR and WXJX, until 2003, when we got the 91.7 slot with 1.9 kw ERP--after I planned the move, and helped get financing, etc. In the ultimate ignomony, they finalized the deal after I left W&J. Oh well.
Anyway, as you know, when you increase height, you normally have to lower power to maintain the same ERP and contour coverage. With around 10 watts of power, at say 60 meters (as the WXJX antenna was) you get full power. But go up to the Cathedral height, can you imagine what power you'd have? That height, you'd be lucky to get a deciwatt. And no transmitter goes that low. Also, I believe the FCC has mandated that these Class Ds keep their assigned antenna height (I'm not sure though).
So, that's the deal: because WPTS (and good ol' WXJX) were such rarities, the FCC was superstrict, and thus, were left with the stuff they had.
Oh, and being totally truthful--I'm sure money has something to do with the sorry state of WPTS.
