Omni-Rig by Afreet Software is a free utility for connecting to many popular radios and to other programs that support Omni-Rig. Select Remote IP in the Port list and enter the IP address and port number for the radio in File>Settings>Radio/Ant>Radio A-D>port.Ī variety of WiFi-to-serial and Ethernet-to-serial adapters are available commercially. This can be done using a native Ethernet port on a radio (such as the Ten-Tec Omni-VII) or through an Internet-to-serial adapter.
Sample schematics are provided below.Įach radio selection has a special provision to connect to a radio through an Internet connection.
Level converters are available from the rig's manufacturer or other suppliers for this purpose, or you can construct your own for a significant savings. Some radios require the addition of a level converter to adapt to RS-232 signal levels. It may be necessary to reduce the Baud rate if communications are unreliable. When the communications parameters are adjustable, it is generally best to set the Baud rate as high as possible to improve communications and control performance. These parameters can be specified in the File, Settings, Radio/Ant window for those radios that are adjustable. Many radios have fixed communication parameters, in which case CommCat sets the necessary Baud rate, data bits, parity and stop bits. In both cases, drivers are required to cause the USB connection to appear the same as a classic serial port.Īny serial port from 1 through 255 can be used. (CommCat supports the Collins KWM-380 through a parallel port.) Some radios now feature USB ports for connection to your computer, or you can use a USB-to-serial adapter if necessary. Radios are controlled by CommCat through serial ports. Use HRD to control your radio and CommCat to help chase DX, feeding frequency and mode data to HRD Pegasus, Jupiter (both with support provided through and external program such as N4PY), Orion, Orion II, Omni VI+, Omni VII
