[amsat-bb] HELP ON LINEAR BIRDS

[Marc Tessier - VE3TES]

Hello, after finally getting my uhf yagi to operate well again, I want to try my hand at the linear birds or SSB sats again, I am having troubles calibrating my uplink to the bird. 
I have read and followed the steps laid out in the FAQ, Yet I still have to recalibrate each pass. what could I be doing wrong???

my station is as follows 

Software - Satpc32
Radio - Kenwood TS-2000
Antennae are - 5 ele on 2m
                    - 9 ele on uhf.

Regards,
