In reply to G0HIO:
As already stated, major dealers will perform the FT897D mod for you for a small charge upon proof of your NOV.
Certainly in the case of the dealer I spoke to, if your radio is still under warranty, if they carry out the expansion, then your warranty will still be valid afterwards.
I modified mine myself after checking information from several sources. There is a little fiddly soldering involved but as a full licence holder it should present no major problems.
Models produced in the past few years cannot be expanded by software alone.
I cannot help with the FT2000 I’m afraid.
Hope to work you on 60m soon.
