All

   Using my 440 M2 oscar beam, SSB pre amp, 70 ft hardline to IC910 with AFC 
on and my PK96 TNC I've been having good results on the D/L with Wisp. Yes 
the U/L has been a challange but with using my stacked M2 L-band antennas, 
60W output and U/L freq set to 1268.698 I've had the best luck so far in 
getting into the BBS. Low elev seems to work best with high passes usually a 
no go.
   Question for the bb, how fast does the sat rotate and where is the L band 
located?
