Let it fall in frequency sequence.  If one used it for 
MW broadcast (US AM band) it would fall between 6 and 160 
but if it was being used for WWV at 10 MHz it would fall 
between 40 and 30 Meters.  This is the way both Icom and 
Yaesu do it.

Alternatively, SWL OUT could simply disable storage of a 
frequency outside of the specific amateur band.  If one 
tuned to WWV on 10 MHz then used the band up/down to go 
to 20 Meters, the 30 Meter bad would be reset to 10.100 
and similarly on the other bands.  It should not be too 
difficult to reset to the bottom of the band since the 
K3 already knows the band edges to disable out of band 
transmit.
