4-2-9. Dual Digital VFO's
Operational convenience is enhanced thru the use of
both VFO A and VFO B.
Two VFO's are provided to allow you to change fre-
quencies rapidly. For example; you could set one VFO
to the lower tuning range and the other VFO to the
upper tuning limit. You can set either VFO to any fre-
quency you desire.
{a) A=B key
Depressing this key causes the data contained in
the inactive VFO (the VFO that is not currently be-
ing displayed) to change to the same data con-
tained in the active VFO (the one currently
displayed). Both the frequency and mode selec-
tion are changed.
For example:
VFO A is set at 145 MHz in AUTO, and VFO B
is 144 MHz in CW. VFO A is the active VFO
(show on the display). Depressing the A=B key
will cause VFO B to change to 145 MHz in AUTO.
(b) A/B key
Allows selection of the desired active VFO. Each
time this key is depressed the active VFO will al-
ternate between VFO A and VFO 8.
