Signal Strength Transition
A task can be set to be performed when the signal level rises and stays above (or falls and
stays below) a certain threshold for a certain period of time. Check the Signal transition
check box, and set the parameters accordingly, if you want to take advantage of this feature.
Used on its own (or with the DSP event), this task can trigger at any time while WiNRADiO
is operating. If you would like it to trigger after a certain time, specify a date and time trigger
event.
DSP Event
This specialised trigger method relies on DSP applets. DSP applets are programs that run on
the DSP resident on the Spectrum Monitor card. Certain external DSP applets can be set to
generate an event to make WiNRADiO perform a certain task. For example, when the DSP
is decoding and monitoring digital data, it could be made to search for a certain sequence
and trigger WiNRADiO to record the transmission.
Each DSP applet can be unique in its features. Click on the Configure button to set up the
applet’s event trigger.
Similarly to the signal strength trigger, you can configure the task to trigger after a certain
date and time by activating the date and time trigger and specifying the date and time.
The DSP and signal strength transition triggers are independent of each other and, if both are
active, the task will activate if either of the two meet its set conditions.
Tasks That Can Be Performed
The three events can be configured to trigger any one of eleven tasks. Select the appropriate
task that you would like WiNRADiO to perform and configure the options associated with
the task.
Change Settings
WiNRADiO can be set to a particular frequency, mode, volume, squelch, attenuator, mute
and power state. By default, none of these settings are changed (frequency, volume and
squelch are blank, mode is set to ‘(N/A)’ and the Atten, Mute and Power check boxes are
greyed). To change any particular setting, specify a value in the appropriate control.
Recall Memory
To recall a memory at a specific event, select Recall Memory
from the task list and specify a memory number to recall when the
event occurs.
Store Details to Log
The current settings and signal level can be recorded to the log file
using the Store details to log task. Specify a comment for the log
entry to be added.
Start DSP Applet
A DSP applet can be activated to perform certain functions,
typically decoding. Select the applet from the list of installed
applets.
Start/Stop Recording
To record the audio to a file automatically, select Start recording.
Select the audio properties, file name and an optional maximum
file size. When the recording starts, it will only be stopped by
manually clicking on the stop button, reaching the maximum file
size or by a ‘Stop recording’ event (and also if the destination runs
low on space, about 5 MB).
