As an aside, the band display does seem to have a factor of 10 error in it.
When 18MHz is selected on the rig, the band shows as 160M and the mode
display functions OK. If the rig is set to 144MHz, the band shows and 20M
and, again, the mode displays OK. Anywhere else, the mode & band tracking
doesn't function. With the FT-817 CAT commands in front of me, I can't see
anything obviously wrong in the rig control file.

It would be interesting to know whether this is an FT-817 quirk, or whether
the FT-897 has the same issue - any FT-897 SD users out there?
