I often use the split mode on my K3, but also the RIT. In terms of sheer
convenience, for casual CW contacts I prefer to use the RIT. Often my
subreceiver is on another part of the band, often in a different mode, and
I'd rather not change it.  

The proposed autospot feature does not add any operating complexity to the
K3 and entails nothing extra to remember or learn. With this proposed
feature, when autospot it enabled, AND the RIT is on, it would merely tweak
the receiver frequency but leave the transmit frequency unchanged. I think
it would be very handy.  The benefit of the autospot feature is that it
enables one to dial in the bandwidth without having the desired signal drop
off the filter edge. To me, that is a very valuable feature.
