Re: AO-51? Mode L/S



  I had a nice conversation with  myself on the first eastcoast pass , about 
1420z today. Sig was 20 over. Next pass I was experimenting with setting up 
auto Doppler tuning with my new d/l converter 910/Satpc32 setup and heard 
n7drb. Bird sounds fine to me during both passes in L/S.
 You will hear the carrier, the bird is in FM mode continuously transmitting 
a strong carrier (no PL turn on scheme to conserve power). Your uplink must 
be off freq or weak so as not to be heard.


 Looking forward to it being in L/S mode for the weekend....
