[amsat-bb] SATPC32 and IC-910H

[Les Rayburn]

I'm very new to satellite operation but have been having a blast for the 
past couple of weeks. Using an IC-910H with attic antennas that include 
a 7 element 432 Arrow
antenna with an SSB Electronics pre-amp mounted at the antenna. 1/2" 
hardline makes the 70' run from the attic to the shack in the garage. 2 
Meters shows a 6 element K1FO Yagi with an SSB Electronics pre-amp and 
1/2" hardline.

Rig is controlled by SATPC32 via the CI-V interface at 9600 baud.

On SO-50, I have no problems with doppler correction as you would 
suspect. With the other birds, doppler is sometimes an issue. Sometimes 
I hear stations strongly but when I call them, I don't hear my own 
uplink and the other station obviously doesn't hear me either.

On other passes, the difference is not so great, and I'll hear my own 
uplink, though usually slightly off frequency.

I know its possible to adjust the uplink frequency in the software, and 
I've tried it during passes without much success. The translated help 
file from German isn't much
assistance to me so far.

Can someone on the list point me towards a better explanation on the 
web, or offer suggestions on how to correct the situation? Any help is 
greatly
appreciated!
