LCD. It is normal, for the microprocessor of the AR-ONE generates the ‘boot up data’
required to control the receiver.
2-3 Squelch Circuit
In normal use,
NOISE SQUELCH
is used. However,
LEVEL SQUELCH
can be selected for
search and scan operations. The
LEVEL SQUELCH
parameter causes the AR-ONE to
check the signal strength of
active
frequencies and to only stop when the signal strength is
above a preset level (which is programmable).
To select
LEVEL SQUELCH
, perform the following steps:
1. Push the
FUNC
key.
2. Push the “
8
” key.
3. On the bottom of the LCD, a bar will be displayed. Using the
SQL
control,
adjust the desired signal level.
4. Push the
ENT
key to confirm entry.
5. Squelch will open only when the input signal strength is above this set level.
6. To select
NOISE SQUELCH
, repeat above steps.
2-4 VFO selection
The AR-ONE has ten (10) VFOs being identified as “V-A” through “V-J” on the top left of
the
LCD. The term VFO historically means
‘Variable Frequency Oscillator’
and today refers
to
a tuneable data store which contains frequency, step, step-adjust, attenuator etc. Pushing
the
VFO
key each time will select the one VFO out of 10. The AR-ONE has an
AUTOMODE setting, and therefore, in most cases a proper receive mode and frequency
