Wes, can you provide any more background about this 'corporate decision'? Not doubting you, just want clarification.
Last I knew as of 14 years ago (when I was one of the techs servicing it, and others), WXL-42 was in WXII's building and on its tower. While I can see that Hearst Telev. can make the decision that they won't renew a lease for a tenant on their tower, I would think that would only apply directly to their own tower, and if a tenant wanted to lease on a tower on a subleased parcel, well, why not? I'll admit, I'm not a lawyer, nor do I play one on stage & screen. Just seems to me Hearst wants all federal agencies off their own towers at the end of lease. YMMV.
Hmmm, interesting: looking at the NOAA NWR website station listing, it says WXL-42 is 1000 Watts. Was only 100 Watts during my tenure. 100 Watt transmitters can be handled by lots of commercial antennas; 10000 Watts needs a bigger, beefier, stouter antenna; If it's still only 100 Watts, it should be easy to move to another agreeable tower.
There's got to be more to the story. But I"m not holding my breath waiting for developments.
