To which I add: Check out the FCC Rules, in particular the ARRL printed version. You'll see a couple of footnotes dealing with power limitations within 100-200 km of various USAF bases around the continental US, including Otis AFB in Massachusetts, Eglin AFB in Florida, Offutt AFB in Nebraska (?), and several others that I can't remember offhand. In fact, the rules were tweaked a few years ago to permit 70cm amateur satellite uplink operation in such a way so as NOT to cause interference with the PAVE/PAWS gear. Also, don't forget that we're now explicitly sharing 449-450 with wind shear warning equipment as well. Also, we cannot use 420-430 north of Line A (to prevent QRM to Canadian land mobile users) nor within 50 miles of certain major US cities along the Great Lakes (Buffalo, Cleveland, Detroit, and some others). In all cases, we're definitely the secondary allocation. 73, Bayard, N1HO, in FN43ig (south of line A, way north of Otis AFB and nowhere near the Great Lakes !) ------------------------------------------------------------------------------ Bayard R.
