You now have your excuse to get the TH-D72A.  :-)  The TH-F6A has two VFOs,
but it is not capable of cross-band full-duplex operation for the

You might want to hold onto the TH-F6A, even if you get a TH-D72A.  The
has an all-mode receiver, which could be paired up with something like an
to make a small station capable of all-mode, full-duplex satellite
operation.   The
TH-F6A's non-FM receiver is not as sensitive nor as selective as other
radios like
an FT-817, but the FT-817/TH-F6A combination makes for a nice station to
off at demonstrations.
