Partie software: Configuration de SDR Console et OmniRig
Installation of additional OmniRig software
SDR Console uses OmniRig to communicate with your device. It allows to control 2 serial channels, so two different sets. It’s time to download and install it.
- Download the software development of Alex VE3NEA on its website DxAtlas. (or directly here update du 07/04/2019)
- After unpacking the file, launch the OmniRig installation (OmniRigSetup.exe). Confirm the standard steps proposed by the setup.
The big advantage of this OmniRig software is that it can be accessed by multiple software in parallel, and therefore without implementation complexity. I invite you to follow the explanations on the use of Omnirig in video. For information, there is a 4-channel version of OmniRig (SDR Console will only manage the first 2 channels). The OmniRig screenshots that illustrate this article are made with this version. You will find it for download on the website of the author Wolfgang HB9RYZ.
In SDR Console, start the controler
- Start SDR Console, (unless you have already done so), configure it to have the satellite transmission frequency display (for QO-100 10489 MHz). You can follow the guide of a previous article Receiving Qatar Oscar 100 satellite with SDR Console, in the View tab, click on Select (right part of the More Options tab…)
- In the View tab, click on Select (right part of the More Options tab…)
On the open window, confirm the option by checking “External Radio”. You must restart SDR Console as proposed by the software
Configure the “External Radio” options
- Your serial link is in place between the computer and the transmitter
- You know the parameters of the serial link expected by your radio, and in particular the speed of the CAT link and that you will report to OmniRig
- Refer to your radio’s user manual to determine its elements
- For a Yaesu FT-817, the serial port speed is indicated in menu 14 of the FT-817 (enter the menu with the F key held down). I use the speed of 38400 bauds.
- To the right of the View tab, click on the External Radio button. SDR Console requests a restart. Confirm.
- After restarting, you will find in the vertical Receive panel, an “External Radio” section. Expand the area by clicking on the line-up.
- Click on the question mark to open the External Radio control panel.
- From this control panel, launch Omni-Rig by clicking on the button.
Configure the panel with known serial link information, in particular:
- Reference of your radio
- and port number: to determine the port number, open the “Device Manager” of the operating system, and identify the COM port in the Ports section (COM and LPT). You can also find this information directly on the Serial Ports tab of this panel.
- Check on the Frequency tab that you are active on Antenna : Same frequency as external antenna
- Switch to the Up-Converter tab to configure the frequency to be controlled. Determine the frequency by simply calculating the difference between the reception frequency and the corresponding transmission frequency of your up-converter transmitter. Example: To hear me on the descent of QO 100 on 10489790.0 kHz, in front of my 2400 MHz transverter, my 2m transmitter must transmit on 144289.5 kHz. The arithmetic difference is therefore 10345500.5 kHz
- Close the window with OK.
- The frequency is now displayed, and corresponds to that of your transmitter.
Serial communication is established.
