Much clearer for the original poster with the distinction between analog and
digital. Didn't think of any of that for some reason. Digital tuning, phase
locked loop and all though can open a can of worms for the newbie to digest.
Despite that all my radios have a digital VFO, when I turn the darn thing I
think of strings and a big capacitor being adjusted. Oh well.

FYI: Modern radios use a digital tuning scheme -- a synthesized VFO
The "large tuning capacitor" types were analog tuning

New Digital types like your R75 -- are in selectable discrete steps i.e.,
from as low as 1 Hertz -- up to 100 kHz see -- page 12 and 13 of the
ICOM
Manual. Also a 1 MHz "Quick Tuning" increment can be used for fast tuning.

Variable Frequency Oscillator--basically the tuning knob, or slew tuning
buttons as the case may be. I believe it to be somewhat more evolved
than
the tuner that adjusts a large tuning capacitor, but then maybe not. In
any
case when you turn the VFO, you are changing the frequency you are
listening
to.

The instruction manual that comes with my brand new R75 talks about
memory
and
VFO. I understand memory, but what is VFO?
