control until the ALC LED оп
JUPITER's front panel begins to flash.
The LED indicates that the transceiver is
generating full power relative to the
output PWR setting.
This control provides approximately 22
dB of adjustment, which should
accommodate most microphones. In the
unlikely event your microphone requires
more or less gain, there is a trim
potentiometer (R72) on the logic board
to provide further adjustment.
3.6.3. VOX Controls
To use the VOX (voice operated
transmit) mode, access the MNU and
move the highlight to the VOX items. To
set the VOX GAIN, ANTI-VOX, and
VOX DELAY controls, select the
required control using the main tuning
knob and adjust it using the MULTI
knob. Опсе set, these controls should
not require adjustment unless operator,
microphone, ог operating position
changes.
3.6.4. VOX бат
Adjust the VOX GAIN Юг desired
transmitter action while speaking into
the microphone. Avoid making the
setting so sensitive that ambient noise
will cause unintentional transmission.
3.6.5. VOX Delay
After setting VOX GAIN, adjust VOX
DELAY for desired transmitter hang
time.
3.6.6. — ANTI VOX
Adjust ANTI-VOX to в level where the
receiver audio does not trip the
transmitter.
3.6.7. MONITOR VOLUME:
JUPITER includes a monitor function
for listening to the sound of your
microphone audio signal in speaker or
headphones. To adjust the monitor
volume, activate the ALT--MON keys on
3-4
the front panel Proceed by pushing
ALT+M-LVL and use the MULTI knob.
The M-LVL setting interacts with the AF
volume control, so work with both
adjustments to set a comfortable volume.
If you monitor with a speaker, place it
carefully to avoid acoustic feedback.
3.6.8. MICROPHONE/ SPEAKER vs.
ACCESSORY INPUT/OUTPUT:
By selecting either MIC or LINE at the
AUDIO SOURCE Menu item, you can
instruct JUPITER to route transmit audio
from either the microphone jack or the
ACC 1 DIN connector located on the
rear panel of the radio. This can
facilitate switching the transceiver
between voice and digital modes of SSB
communication without moving cables.
3.7. SWEEP FUNCTION
Тһе SWEEP control enables JUPITER's
spectral display. И provides а way to
view active frequencies in the visual
format of a spectrum analyzer. И can
help locate activity (or inactivity) on a
given range of frequencies. Pressing the
button mutes the audio for a few seconds
while JUPITER quickly scans a range of
frequencies below and above the
frequency set by МЕО А A vertical
dashed-line cursor follows the
movement of the MAIN TUNING knob
to show the tuned frequency in relation
to the SWEEP display.
See the SWEEP RANGE MNU function,
Table 3-2, to set the SWEEP range with
the MULTE control.
3.8. AUTOSWEEP FUNCTION
Enabling this menu function will cause
JUPITER to perform another spectrum
sweep as soon as the operator tunes the
receiver outside the existing sweep
range.
