[amsat-bb] vo-52 and the linear transponder

[normn3ykf@stny.rr.com]

Hi all!!
Have been reading the mail regarding the lack of activity on vo-52. Have made several attempts in the past to work this bird. 

Given that the 144 MHz uplink is lsb and the downlink is usb (inverting), what should I expect in terms of doppler shift?

I would assume that the downlink will shift up (assuming that the bird is ascending), and down when it is descending (away). Or do I have it backwards?

How much will it shift?

I can hear the bird, and do have the necessary gear.

Thanks,
