Hi Mike, when I work satellites from mobile (mode J-V/U) I only compensate the doppler on the receiver (also a SSB handheld receiver). You can see what I'm talking about in this video working the FO-29 (similar to the HO-68):

Best 73 and good luck!

I'm a relative satellite newbie, and hence I don't have a base station set up. I do have a 2m SSB rig and an HT capable of SSB reception up at 435 MHz, as well as an Arrow antenna. With that in mind, does anyone have any tips for making contacts via the linear transponder on HO-68? Other than keeping my antenna pointed in the direction of the bird/rotated to avoid fades, how much do I need to compensate for doppler on the transmit and receive rigs? If I only tweak the RX rig, is that acceptable? Also, how much power should I use? Thanks for any advice this list might have!
