My question is whether or not you were making contacts S&P during the time that this was occurring. If you WERE making contacts, then split was not on, and you have a problem of the B VFO frequency getting into the A VFO cable.
If you do not have the KRX3, then the the single KSYN3 is switched back and forth and there is no possiblility of the problem you speak of unless you WERE actually transmitting split and the [SPLT] marker on the display would have been showing, just to the right of the [SUB] marker. But since you were talking about [SUB] I assume you have the KRX3 and a PAIR of KSYN3, and VFO B is the running frequency of the second KSYN3. You need to check both mini-coax ends of every cable coming out of either KSYN3 and the KREF3. It is very easy for those to be not fully seated. Also, if you have an older K3 and either KSYN3 is lacking the stiffener mod, you should do this. A beneficial side effect of this mod is to increase shielding to the KSYN3's. You can see illustrations of this mod at http://www.elecraft.com/manual/ELECRAFT%20KSYN3%20Stiffener%20Mod%20Rev%20D.pdf 73, Guy.
