One problem with the Yaesu 736R is that when the rig is under computer control
you can't grab the tuning knob and hunt around the passband for someone to talk
to. "Tuning" directed by computer is agonizingly slow and tedious, taking
about a second per change, so that's out. And since the rig's frequency cannot
be read by the computer, you can't hunt manually and then lock things in on the
computer. (I suppose I could re-write my CAT client to allow me to visually
read the frequency off the display and type it in, but that would be tedious
too...)
So, for me, SSB is full manual. FM is full computer. (and CW is wishful
thinking) Sometimes I'll use the computer to get my manual tuning started,
picking mid-passband to get the VFOs close. Then I disable the computer, send
a few dits to verify, flip to REV to lock the VFOs, and go manual from there.
If you run full manual often enough, it becomes second nature. I used to be
able to find myself on RS-10 in just a few seconds, anywhere in the passband.
But that was a REAL "EasySat".
