Blanker
Be sure the TMB switch is in the Middle
position. By pressing the NR button once you
will toggle the noise blanker on. NB will be
shown on the top left side of the screen.
Pressing the NR button a second time will
turn off the noise blanker and turn on the
noise reduction. Pressing the NR button a
third time will turn on both the noise blanker
and the noise reduction. Both NR and NB
will appear on the left side of the screen when
toggled on or off.
To adjust the how aggressive of either the
noise blanker or the noise reduction follow
these steps: Begin by turning both NR & NB
off so you can begin setting these features
independently. Ensure that the TMB switch
is in the Middle position. Ensure that the
bandwidth control is pointing to 12 o'clock.
To adjust how aggressive the noise blanker
operates, press the NR button (1 beep). Press
and hold the NR button one more time (1
beep) You will now see (nb) displayed on the
screen with a numerical value just left of the
SWR/PWR meter. Use the main VFO knob
to change to the required value. Press the NR
button one more time to set the desired value
to the Argonaut VI.
To set how aggressive the noise reduction
feature works toggle the NR button until just
the NR appears on the left side below PWR.
Follow the directions above to set the desired
value to the Argonaut VI.
Exit by toggling the NR button until the
NR/NB or both disappear from the screen
