2.4. SSB Mode Operation
Be sure the TMB switch is in the Middle
position. To begin SSB operation toggle the
MOD button to either the LSB or USB for the
mode of you wish to operate. The Argonaut
VI will display the last mode you have
selected when toggling through the bands.
Note: Remember to set the PBT (4) control
to the center of rotation so the side band
signal is centered in the desired filter. This
results in a starting point for proper side band
audio.
Monitor Level (3, 5, 7)
To monitor your SSB, audio input levels, or
Speech Processing level, a built in monitor
can be heard best with a set of headphones
connected to the Argonaut VI. To activate
the monitor feature you must first set the
Argonaut VI into either LSB or USB. Be
sure the TMB button is in the Middle. Rotate
the bandwidth control until switched to the
CW position. Press the BAN button and you
will see (
nnon
LUL
) on the screen. The level
can be adjusted from the main VFO knob and
a level amount will be displayed on the
bottom center of the screen. 0 means no
Monitor output, and non-zero means that %
will be added to the speaker and headphone
outputs. The level is still active whenever a
non-zero value is used and will be heard in
voice transmit modes when transmitting
regardless of whether the monitor is in the
adjustment mode or not.
Speech Processing (3, 5, 8)
Be sure the Argonaut VI is in the USB or
LSB mode. To turn the Speech Processor on
be sure the TMB switch is on the Bottom.
Rotate the bandwidth control until switched
to the CW position. Press the MW (PRE)
button. The screen will display (
SP PrOC
)
.
Adjust the desired amount of processing with
the main VFO knob 0-9. When set at zero the
procesor will be turned off. Any setting from
1-9 will be active and remain on all the time
when in side band modes. To exit simply
press MW (PRE) and the main frequency
display will be brought back on screen.
Remember: When you are finished making
adjustments to Monitor Level and Speech
Processing values, turn the BW pot
clockwise from the CW position to return
the Argonaut VI to normal operational
modes.
Auto Notch (9)
The Argonaut VI provides an Automatic
Notch feature. AN will operate in CW and
Voice modes. To turn it on and off requires
that you select USB or LSB mode. Then
rotate the bandwidth control until switched to
the CW position. Press the NR(9) button. This
toggles the AN setting. There is no indication
on the front panel for Auto Notch. When you
press the NR (9) button, 1 beeps means that
Auto Notch is disengaged, and 2 beeps means
that Auto Notch is engaged. Auto Notch state
is not remembered during a power cycle, and
it will default to Off upon power up.
