SDRuno User Manual
3.3 Selecting an input source
The default input device is the SDRplay RSP. If there is no available RSP, either none are connected or
all connected RSPs are in use, SDRuno will load an ExtIO dll from the SDRuno folder and as long as the
relative hardware is connected and ready. This then becomes the default input device; otherwise the
default input device is the last selected WME driver (soundcard). The WME input and ASIO I/O device can
be selected in Main->Settings->Input Tab; here you have also indication of the ExtIO dll loaded at start-up
(if any).
If no WME specific device has been selected, the system default (sound mapper) will be used. If you wish
to use ASIO devices you must select an ASIO driver. Input source selection is done on the Options
menu: OPT->Select Inp
ut. Let’s take as an example that you have a Perseus connected and the
ExtIO_perseus.dll loaded. If the hardware is powered and ready, you should have it selected as the input
source.
3.4 Selecting an output device for a VRX
As already seen previously, each VRX can have its WME output device. More VRX can share the same
WME device. Output device can be selected in RX Control->Settings->Out Tab. If no device is selected
(default) the VRX will use the system default (sound mapper).
3.5 Selecting input SR (WME and ASIO input only)
Input SR selection is done in Main->SR button: the SR menu will popup.
3.6 Starting the DSP engine
Now you are ready to test your setup: click on the big button “START” in the main window. You should
hear noise or demodulated audio and the spectrum windows should also work.
3.7 Setting the RX frequency
You have multiple choices for inputting a frequency value:
-
Clicking on one of the band buttons (under the S-meter in the RX Control window).
-
Moving the cursor to a specific digit in the frequency display (inside the RX Control window or
inside SP1 if the dial is enabled) and turning the mouse wheel.
-
Using the current tuning step turning the mouse wheel (when the cursor is outside any control and
one of the VRX windows has focus).
-
Entering the frequency directly with the mouse and/or the keyboard.
-
Clicking on the Main Spectrum window (spectrum or waterfall); the actual selected frequency is
the nearest multiple of the current tuning step.
-
Using the Memory Banks features.
-
Using a dedicated hardware controller (Tmate
– Tmate 2).
-
Using CAT control and/or Omnirig.
3.8 Changing the tuning step
Right-click on the RX Control frequency dial: the dial step menu will popup. Select the desired tuning step.
