cw sideband -- rcvr or xmtr determines?

Who/what determines the frequency -- the receiver or the
transmitter? Seems like a simple enough question at the
surface, but in fact one I suspect is confusing many by the
posts on this subject.

Let me suggest that it is the transmitter that is/should set
the frequency, as was the example of the 7.040 xtal. (But
how do you know this unless you are using a xtal.)

Others, users of the fixed offset transceivers for instance,
might suggest that it is the receiver that sets the
frequency. That seemed to be suggested by some of the
replies.

Say you want me to meet you on 7.040. With my xtal HW-16
that is fine as long as I have a 7.040 crystal. I just
tune up, listen around with the receiver, then fire off
the CQ (assuming the band is free). Common practice when
we were all rock-bound was to tune around as split
converstations were common. But with the Icom 751A (another
person's example, and a xcvr I've used twice), what do I
tune to? If I set the dial to read 7.040.00, what was I on?
 7.040 or 600/700 off from that? I always wondered as when
I pushed the mode switch between CW and SSB, I saw the dial
also shift. Obviously the offset coming in to the play. So
where am I? I didn't worry at the time because I matched
tones when I tuned and kept RIT always centered.

I am not surprised that people are confused on this. My
($.02, although phone charge for this long of a message is
likely more than that collectively :-).
