you've already got it figured out.
The main receiver on the ts2000 has two independant VFO's.
These can be used at the same time, one for receive, one for transmit...or 
they can just be two separate VFO's...for instance, if you want to work 
split, you set VFO a to your rx frequency, and VFO B to your tx frequency. 
Or, you can simply have one VFO say on 14.285, and the other on 7.158 so you 
can toggle between two frequencies quickly.
The sub receiver doesn't have two VFO's really, but does allow you to use 
split operation or repeater offset they call it.
Based on your comments, I think you have it figured out anyway.  It's not as 
complex as you may think.

Subject: Please Help Me Better Understand "VFO A/B" vs. "Main/Sub Receiver" 
Capabilities on the Kenwood TS-2000

Hi!



I need a bit of help to better understand these two capabilities.  Yes, I
have read the manual and I will read it again several times; but this is not
getting me to a proper understanding.  So, can you please help me grasp the
following:



1.  VFO A/B operation is not the same as operating on the Main/Sub receiver
simultaneously, right?  That is, you are not transmitting on one receiver
(Main/Sub) and receiving on the other.



2.  VFO A/B operation happens on the same, single receiver, right?  That is,
it can happen on the Main receiver, but VFO A/B operation cannot be done on
the Sub receiver, or can it?  When they speak of VFO A/B operation "A" and
"B" are *not* referring to the Main and Sub receivers, right?



3. I *think* VFO A/B operations refer to utilizing "split operation"; which
has something to do with transmitting/receiving on different frequencies but
all on the same, one receiver (i.e., either the Main or the Sub).
Conceptually, it is sort of like the notion of offsets when, for example,
using 2M repeaters - or so I presently understand it.  Is this fundamentally
right?



I appreciate your helping me get my head around these concepts and
capabilities.
