Yeah, maybe on 435-MHz but try doing that at 1268 or 2400 on the 
Leos!  Not very easy/practical.  One hand tunes the uplink, other 
moves azimuth, third the elevation, and fourth keys the mic...fifth 
keeps the log...uhuh.

I find operating ordinary old mode-B or mode-J hard enough and think 
auto-tracking (at least) is made for the Leos.  For AO-10/13/40 its 
non-issue, of course, Doppler rates and tracking rates are lower.
