[amsat-bb] doppler tuning problem

Hi all,

Now that I finally have SatPC32 working with my 817, I'm having a new issue with Doppler tuning on the SSB birds. I tune around the passband until I can hear a station clearly. When there's a break, I transmit my call. The other station will hear me, but by the time the reply comes, I can no longer hear them clearly. It's almost as if the automatic Doppler tuning either can't keep up with or goes too fast to stay locked onto the correct frequency. I know its not the other station's frequency adjustment because this happens when there's a QSL already happening and they seem to be Doppler shifting at the same rate.

Any suggestions?

Thank you,

Tim
