This is an issue with recent Yaesu rigs that I have been meaning to 
address. The issue is that sending a CAT command to go to a frequency in 
a different band is not the same as switching the band then changing the 
frequency "in-band". Aerial selection and a couple of other settings 
like AGC are stored with the band not the frequency.

All the CAT programs have to take special action for Yaesu rigs to work 
out the target band, use the band change command(s) to get to that band 
then set the final frequency. Few actually do this :(
