USB Configuration

 The most common way of interfacing your radio to the computer is via a standard A/B type USB cable. No other cables or interface (e.g. SignaLink, Rig Blaster, Rig Expert, or other interface) is required because this USB cable provides the connection for the Rig Control and it also carries the Audio for the radio's built-in soundcard which is accessed by a "USB Audio CODEC" once the proper driver from the radio's manufacturer is installed.

Below is an image of the USB cable we recommend. Notice the "Ferrite Chokes" on each end of the cable. These chokes help prevent RF radiation, which may be present in any shack, from feeding back into the computer, which can sometimes cause some very strange behavior in the HRD software. If the cable you are currently using or plan to use doesn't have the ferrite chokes, it's recommended you purchase some of the "snap-on" chokes that are available from or on eBay and attach them to the cable you are using.


The USB interface provides for Rig Control and an Audio Codec for the radio's internal soundcard. This method requires a Virtual Com Port driver, which can be downloaded from the radio manufacturer's website.





Insure you have installed the Virtual Com Port drivers for your radio or interface before connecting the USB Cable to the computer. Connecting the cable before installing the

proper driver could result in a "Generic" driver being installed by Windows which could result in issues later on. Follow the manufacturer's instructions to install the drivers, or, if you have problems locating or installing the drivers, please contact the device manufacturer's support team for assistance.




 You may need radio's owners manual to learn how to access the radio's menus and change settings needed for operation with the HRD software. If you don't have the manual for your radio, you can download it in a PDF file from the manufacturer's website.
