[Elecraft] Spotting DX

[Paul]

I've only had my K3 on the air for a couple days...trying to figure out all the bells and whistles.

Here's my problem:

K4M (Midway DXpedition) is transmitting on let's say, 7.004 listening up 25.

So I go SPLIT, tune VFO B up to about 7.020. Now I want to spot the guy he's working and transmit there right afterward.
I'm looking for the guy, I hit REV and listen. I don't hear him, so I want to tune up or down and find him. But when I turn VFO A's knob (which is showing my Xmit frequency, the VFO B display (K4M's run freq) also changes, so when I drop REV I'm no longer on his 7.004 frequency.

How are you supposed to do this? Is there an option that ties them together somewhere? LOCK is off.

I used the SUB receiver, and then I can listen to my xmit freq in one ear, but that doesn't seem necessary.
