External Radio





External Radio Integration

Before you can use this option you must enable it. From the ribbon bar's View pane select More Options... and enable External Radio.

After restarting the console the display is added to the Receive DSP panel.

Antenna or IF Output?

You must decide how the SDR receives signals, either using its own antenna or connected to the IF Output of the external radio.


This is the recommended option.

There are several ways to connect your SDR to an antenna:

  • Sharing the main antenna with the external radio via a switching box such as the excellent RTR-1A from DX Engineering.
  • Connected to a RX Out connector on your radio. Not all radios have a RX Out, the FTDX-3000 does.
  • Connected to a specialised receiving antenna such as the Wellbrook Loop.

IF Output

When you use the IF Output from your radio the same frequency is used by the SDR irrespective of the frequency which the external radio is tuned. An example of a radio supporting IF Output is the FTDX-3000 with an output frequency of 9MHz.

The software must make the necessary changes in frequency so that the external radio's frequency is displayed, not the IF output frequency.


  • The IF Output signal may not have a flat response,
  • The IF Output bandwidth may be restricted,
  • As you tune with the console the display may show erratic behaviour.





This software uses OmniRig from http://www.dxatlas.com/omnirig/ for radio control. OmniRig must be installed before using the external radio display, see below for more information.

To configure Omni-Rig you must open the external radio options, to do this press the ?button in the external radio window.

  • Use the Serial Ports page to find the ports on your computer.
  • In OmniRig set the Poll Int. ms (polling interval in milliseconds) to 100 (or lower if supported). If you do not set a low polling interval the response will be sluggish.
  • Check the baud rate selected in OmniRig and the baud rate on your radio are the same. A higher baud rate will give a better response but can return erratic values if set too high.
  • Check the OmniRig website and support groups for your radio to ensure you have the latest OmniRig support files (.ini).

April 23rd, 2016: the file to download and install is on http://www.dxatlas.com/Download.asp the file is OmniRig http://www.dxatlas.com/OmniRig/Files/OmniRig.zip , this contains radio definition (.ini) files. The very latest .ini files are in http://www.dxatlas.com/OmniRig/Files/RigIni.zip .


In the Logfile pane you can enable [X] Verbose logging and the [X] Debug option when helping diagnose problems. When debug is selected all entries written to the logfile are also sent to the current debugger, for example DebugView which is downloaded for free from https://technet.microsoft.com/en-us/sysinternals/debugview
