On the FT450 one must select the target VFO using the VSn; command
before attempting to change the frequency. Ths change does that and
reverts the current VFO if necessary.
for the latest Yaesu backends (ft9000 and later that use "New CAT"
commands) and set the default "write_delay" parameter to '0' as these
radios deault to assuming a command has been received after 10 mSec of
no data on the wire. The default write_delay had been 50 mSec (for no
good reason except I copied and pasted from older backends) which was
too long as these models implement a CAT TOT (Time Out Timer) of 10 mSec.
