The WiNRADiO scanner can also alert the operator by means other than the scanner dialog
box. The operator can be alerted by an audible beep and/or by sending data on a parallel
port, typically for remote notification.
WiNRADiO can have two separate squelch settings: one for audio and one for scanning.
This option is specified under ‘General Options’ in the ‘Configure’ menu. If this feature is
enabled, another control is visible at the bottom of the dialog box. It allows you to specify
the scanner squelch while the audio squelch remains controlled from the main panel.
Exclusions
To avoid the scanner stopping at unwanted
frequencies, your WiNRADiO software can
maintain a frequency exclusion list. The
exclusion list contains a list of frequency
ranges which are skipped by the scanner.
During a scan, you have the option of adding
frequencies to the exclusion list by clicking
on the Exclude button (this option is enabled
by checking Enable excluding while
scanning at the bottom of the ‘Scanning
Exclusions’ dialog box). The range that is
excluded depends on the mode. In CW, LSB
and USB modes, the default range excluded is ±999 Hz, AM is
±1.999 kHz, FMN is ±6.249 kHz and FMW is ±49.999 kHz of the current receiver
frequency. If you want to change any of these default values after they have been added,
select the exclusion from the list and click on the Edit button.
You can also manually add exclusions by clicking on the Add button, edit or delete existing
ranges. There is no priority system, if the frequency is within any range in the list, it will be
ignored by the scanner.
Miscellaneous
Mute
The Mute button controls the audio output of your WiNRADiO receiver. If it is on, the
output is muted (switched off). To activate (or deactivate) the mute control, click on it or
press Ctrl+U.
Passband Tuning (IF Shift)
In CW, LSB and USB modes, a control is enabled at the top-left corner of the
panel to allow you to adjust the passband tuning of the receiver. This controls
the quality of the audio reception of an SSB transmission. The IF can be shifted
up to 3000 Hz above or below the normal location.
To use the control, click on the display and enter the frequency in Hz. To set
the frequency from the keyboard, press I or Ctrl+B and enter the frequency. To quickly reset
the display to 0, press the Reset button or the ‘star’ key on the numeric keypad.
Indicators
The three LED-like indicators indicate various states of your WiNRADiO
receiever.
The squelch indicator, ‘Sqlch’, is green when the squelch is inactive (the
audio output is open), and red when it is active or about to activate
(depending on the ‘Squelch delay’ time specified under ‘Configure - General Options’).
