|Fldigi can display
decoded signals in both PSK and RTTY modes. The multi-channel
display is either a separate dialog or an embedded resizable panel.
|1) select the number of
100 Hz channels you want visible
2) select the start frequency for the browser (your transceiver may
not rx signals below this value)
3) select the inactivity timeout for the browser. After this
number of seconds the channel will be cleared and prepared for the next
4) select what kind of label annotation you want on each line
5) select the font and font size to be used in the browser
6) You can enter any text you want to search for in the Seek Regular Expression widget.
This text can be a simple text snippit such as "CQ" or any
regular expression. When the regex is satisfied in a channel the
text color for that channel is changed to red. With a regex you
can specify a more generic pattern, which means that
you can match more things and your search is somewhat noise tolerant.
Here is an example for a CQ from a US station (should match most
This says "cq followed by at least one character, followed by one A,
K, N, or W, followed by an optional letter, followed by a digit,
followed by a letter that is not q, followed by one or two letters".
The search is case-insensitive.
All plain text is a valid regular expression, unless you really had
looking for these metacharacters:
These will have to be escaped with a backslash.
7) select whether you want a marquee type of continuous scrolling, or
simply clear the line when it is filled.
8) select whether you want the lowest frequency at the bottom (checked)
or the top of browser panel
9) select whether you want the audio stream history buffer to be played
back when you select an active channel. The first-in first-out
audio history represents the previous 2 minutes of received audio.
10) Both the background and slider hilite colors can be selected for
the signal browser detection level control. The default colors
are shown in these images.
11) You can set the 2 levels of text hi-lighting that is used in the browser lines
12) You can set the background colors for the odd/even lines and the line selection color
- HiLite 1 - Text color when the regular expression evaluator finds the target text
- HiLite 2 - Text color when your call sign appears in that receive channel
