SSB Operation
The
SSB
H
OME
S
CREEN
,
contains all the controls and indica-
tors that are required for Upper Side-
band
– USB, or Lower Sideband –
LSB operation.
The
Mode
is shown in the upper left
(USB) along with the state (RX).
The
Setting
is displayed in the lower
left corner. This shows which option
is currently controlled by the left rota-
ry encoder (AF Gain) and its present
value (55).
The
LO Freq
widget is shown on the
lower right corner with a frequency of
7236.0 and the tuning step is 100 Hz
(indicated by the “grayed out” two
least-significant-digits of the frequency).
Also shown is the name of the memory button associated with the
Memory Manager
, in this
case
M12
.
There are four control buttons on the screen:
AGC
,
WF/Sp
,
Filter
, and
Mode
.
The
AGC
button controls the selection of the Automatic Gain Control. Repeated touches of this
button cycle through the various AGC modes.
The
WF/Sp
button enables selection of the Spectrum or Waterfall FFT display.
The
Filter
button allows selection of the audio bandpass filter, as previously discussed.
The
Mode
button allows you to quickly change to a different operational mode (CW, LSB, USB,
PSK-L, PSK-U).
In the upper right corner of the display is the FFT Spectrum window. It shows a spectrum dis-
play, or panadapter view of a 4kHz portion of the spectrum. See Figure 64 and Figure 65.
This spectrum display allows you to see the signals in your 4kHz chunk of the radio spectrum.
A taller blue bar indicates a stronger signal. If there are nearby signals in the band that are
strong enough to interfere with the intelligibility of the signal you are trying to copy, the spec-
trum display will give you an idea of how bad they are and how likely it is that you can select a
narrower filter to exclude them from what you are hearing.
