Thank you, I hadn't seen it mentioned before and with the apparent sudden loss of contact with the school today I wondered how doppler was handled.
Thanks again and keep up the good work!

Yes the ground stations compensate for Doppler on the uplinks and downlinks during the contact. They use any of the standard methods to adjust for the +/- 3.3 KHz Doppler. Manual control via a prediction table, preprogrammed memories or computer control of their rig.

Sorry Ken and Tim...
I guess my real question should have been..."do the school ground stations compensate for doppler on their uplinks during their contacts?"
