Entering Frequencies (Using Keypad) & A=B - AOR AR8000 Operating Manual

6-4 Entering a frequency through the keypad - VFO (MANUAL) MODE
& changing from VFO "A" to VFO "B" and [A=B]
The AR8000 receiver has a 2 VFO system being identified as "A" and "B" on
the LCD to the left of the frequency readout. The term VFO historically means
"Variable Frequency Oscillator" and today refers to a tunable data store which
contains frequency, mode, step, step offset and attenuator information.
Both VFO frequencies are displayed in parallel
format on the LCD one above the other. The
"active" VFO (the one which is currently receiving)
is displayed on the second line and the "stand-by"
VFO on the third line below.
Press the [2VFO] key to first select "VFO mode"
(should the receiver be scanning or searching etc).
Each time the [2VFO] key is pressed VFO "A" and
VFO "B" alternate between active and stand-by.
The first time you enter a frequency via the numeric keypad, it is best to first
press the [2VFO] key to place the receiver in a known state of operation. The
condition of "VFO" (1VFO) or "2VFO" is generally referred to as manual mode.
Press the [2VFO] key so the "A" appears on the left hand side of the second
line of LCD. This indicates that "VFO A" is the active VFO. This condition is
referred to as "2VFO" mode with VFO B as stand-by.
If you find the twin frequency display confusing, press
[SRCH] [SRCH] (when no signal is present or
[SRCH] [ENT] if the frequency is active) so that only
a single frequency readout is displayed, this is
referred to as "1VFO" mode. Both 1VFO and 2VFO
modes may be referred to simply as VFO mode or
MANUAL mode.
Equalising VFO data [A=B]
The contents of the active VFO may be quickly copied into the stand-by VFO
by pressing [FUNC] [2VFO] while in VFO mode. Equalisation of VFO data in
this manner is useful for bringing both VFO A and B onto the same band and
in the same mode and step size etc.
It is not possible to copy the contents of the stand-by VFO into the active VFO.
Instead press the [2VFO] key to change the positions of the VFOs (active
becomes stand-by and visa versa) then use [FUNC] [2VFO] to equalise the
VFO data.
VFO equalisation (A=B) is also convenient for quickly setting up a manual
search (see section 13-1 of this manual for further information regarding
manual search).
