Argonaut VI

BW (3) Bandwidths

Adjusting the BW control will allow you to
select the DSP filtering of your choice. This
will increase the selectivity of receive and
helps remove close in unwanted signals.
The range of the DSP filters is 100hz to
2500hz in 25hz increments. When the
optional 6kHz filter is installed, this permits
4k, 5k, and 6k DSP bandwidth selections.
When dealing with crowded band conditions
and close in adjoining signals one will find
this control very useful as you begin to
narrow the filter to eliminate close in
unwanted signals.
automatically select the correct roofing filter
ahead of the DSP filtering provided a specific
roofing filter is installed.

PBT (4) Pass Band Tuning

Verify that the PBT control is at 12 0'clock to
begin listening in all modes.
The PBT control will allow you to move the
passband back and forth across the desired
signal. It is beneficial in dropping QRM out
of one side or the other of the passband or it
can simply be used to improve the quality and
intelligibility of the signal.
experiment for digital communications is to
work the PBT control along with the BW
bandwidth control for the greatest selectivity
and interfering signal rejection.
