Hi Ron, "Channelization" is a subject that is beginning to create more and more debate on the air. I must admit that, being a 6m operator where channelization makes sense other than in a contest environment (the band is large -- why QRM each other?), I might have a predisposition in that direction.
But aside from the channelization debate, yes, I understand your initial objection. The way to solve that is to simply leave the actual VFO frequency unchanged when pressing the COARSE button -- but as soon as the VFO frequency is moved, drop the offset. Part of my "intuitive" feeling about this undoubtedly comes from how the TS-2000 was designed to work, and I guess I'm used to that. I don't know about current FT amd IC rigs.
