[AMSAT-BB] Manual Doppler (SSB) with dual 817's

I run dual Yaesu 817's with an arrow handheld antenna. I have no problem using the PBR cheat sheet for finding myself when I'm calling CQ on RS-44 using the UP/Downlink Frequency . Searching and pouncing is proving to be more difficult in finding myself. Any tips? I'll look on the chart and estimate where I should be based on the time of the pass, but for some reason I can't seem to locate myself, I guess it just takes practice....
