GE-3 at 87 degr. west is quite easy to find. In order to get any signal
switch to 12.100 GHZ, vertical. PBS uses this txp. on a 24h basis in
analogue technique. Good enough for aligning the dish. Turn your dish to
azimuth (magnetic) 193.9 degr. and adjust the elevation to 57.4 degr.
This are the values for Tampa/Fl. In the Ku-band the bandwidth is 36 MHz
and txp.4  is on 11.780 (X). The EIRP in your area should be around 46
dBw, which needs a 90cm dish (C/N Ratio 10). We have here in Europe no
information on the planned service by USAF. My advice is,  to search on
the given transponder during the testperiode for a signal or contact the
trasmitting site. Otherwise try it via G.E. (http://www.ge.com)
