Hello folks,

I have been mostly mode B user on AO- 7 satellite but 
today I decided to try mode A  from my summer QTH. I have two
for downlink (vertical and Spiderbeam with four elements for 28MHz) and 
no problems for receiving signals from the sat. Of course because of 
the polarsation change switching between these antennas during the pass 
gives best results.
For the uplink I have used FT-817 (5w power) to 9-
element yagi, unfortunately SWR is high above 145MHz. On every pass  
that I tried today I have heard my own signal on downlink (weak but 
What is the recommended power level for mode A (if there is 
one)? From my previous visits to my summer QTH I have heard some 
japanese stations and satations from stateside, so this mode would be 
worth to try. On mode B from my city location
5-15 watts is well 
enough. What kind of antennas people are using on mode A?
