Tuning of the VFO Setup Memory

The FT-450 Transceiver maintains three active VFO setups; M-TUNE, VFO-A and VFO-B. One
of these three setups, known as the primary VFO, is indicated on the bottom right hand corner of
the display. The operator has the ability to directly change parameters in the primary VFO setup.
If a memory channel is selected to control the primary VFO, its name shows on the bottom right
hand corner of the display. Should the operator decide to change one of the parameters (see
Table 8 above), the entire VFO setup of that channel is copied into the M-TUNE memory and
the change applied to the M-TUNE memory. M-TUNE is now the primary channel. Neither the
memory channel nor VFO-A nor VFO-B have been changed at this point.
If either VFO-A or VFO-B is selected to
control the primary VFO, any changes
in the parameters of Table 8 above are
made directly to VFO-A or VFO-B
respectively. When either of these VFOs
is associated with the primary channel,
the other acts as the secondary channel.
The primary channel provides all the
settings for reception as well as those
for direct transmission. The secondary
channel provides parameters for
transmission during SPLIT
transmission.
There are two buttons available to
change the contents of the secondary channel in the FT-450.
