Is the station to which you refer located in some sort of local Federal
Building up there in Albany?
Maybe you could put some sort of small shield-room enclosure up on the roof.
Put the station in there, and do a remote access kind of thing.
You might be able to get some funding from DHS.
If there is a COTHEN facility in the area, you might be able to access that
via the web, or maybe install your station there with the other comm.
equip. and access it independently of the other COTHEN Resources.
Is there a HFGCS Facility on Stewart ANGB down in Newburgh?
Maybe you could remote some equipment there.
A local organization of some sort put a non-Federal-owned NOAA WX Broadcast
outlet up on one of the ski slope mountains some years ago, up near the
Chestertown or Warrensburg area, I think. A remote there? (KW2Q, ex-N2LAQ
was involved with that.)
Or maybe over on Albany Airport - they CERTAINLY can't tolerate RFI there!
On RPI Campus, maybe?
Or, one of the facilities of the Champlain & Hudson Canal?
Heck, the State Police Barracks outside of town.
