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.
