One of the things I like most about MacDoppler is that I can turn the 
VFO and it will follow me. It does not enforce that I use the program to 
change frequencies. That allows one to use a simple VFO know interface 
to change frequencies while still having full Doppler correction.

SatPC32 provides three methods to tune across the passband of a linear 
transponder while under full Doppler control:

1. With the radio's VFO knob
    (most peoples' preference)

2. With the mouse, by clicking the on-screen tuning buttons
    (for example, to go up 5 kHz with a single click)

3. With the keyboard:
    up/down arrow keys for 100 Hz increments
    left/right arrow keys for 20 Hz increments
    +/- keys  for 10 Hz increments

Methods 2 and 3 only work when SatPC32 is the active program window. 
They don't work if, for example, your logging program is the active window.

SatPC32 doesn't force users to start Doppler tuning in the middle of the 
passband.  That's the default, but it's easy to modify the Doppler.SQF 
file to start away from center, or on the beacon frequency.
