LR,

I guess today "VFO" is a manufacture selling feature "BUZZ" Word.

Except for the earliest receivers all radios have some form of "VFO"
(Local Oscillator)

Long age Amateur (HAM) Transmitters and Transceivers were 'fix
frequency' and Crystal Controlled for frequency stability. The
external [High Stability] Variable Frequency Oscillator (VFO) was an
up-grade for old HAM Radios. Then the next step was, a new 'needed'
selling feature of a HAM Radio became a built-in "VFO". Finally
BCL/SWLs were sold on the 'idea' (a selling concept) that quality
"Communications" Receivers needed a "VFO" to be the equal of the HAMs
Transceivers.

TBL: The "VFO" is a good and needed feature of any modern
Communications Receiver.

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