2VFO
Twin VFO frequencies (A & B) may be displayed on
the LCD simultaneously, one providing a stand-by
frequency available for quick transfer (similar to
commercial aviation built-in radio transceivers). The
two VFO systems operate independently of each
other and store frequency, mode, channel step, step
offset and attenuator status.
Alphanumeric Display
Each memory channel and search bank can be given
a specific title using alphanumeric comments up to
seven characters in length. The addition of com-
ments which may be entered via the keypad/rotary
encoder or through the computer port greatly eases
the identification of radio channels or stations.
The dot matrix display provides additional information
such as frequency readout, S-meter and band scope.
When entering data into the receiver (such as
frequency), the AR8000 display provides helpful text prompts to ease
operation.
Band Scope
In VFO mode the AR8000 can check adjacent
channels for activity (five channels each side of the
centre frequency). The information is displayed by
means of vertical bars (like a graph) on the LCD and
is updated every five seconds or when the DIAL is
turned.
Wide variety of search & scan facilities
Great flexibility is offered by the microprocessor. Search & scan may be
selected using various parameters such as:
Select scan - where memory channels are "tagged" for scan, this is useful
when scanning is required for only a few memory channels.
Delay search / scan - where the receiver will resume scanning when the
channel clears after a predetermined time (default 2 seconds, programmable
range 0.1 to 9.9 seconds, HOLD or OFF).
Audio search / scan - the receiver checks the channel for valid modulation
(voice) appropriate to the selected mode, default is OFF.
