CAT Command Information

CAT Command use with the RoMac 10 Band Equalizer

Starting with version 3.0.0 there is CAT command support for many of today's popular radios.

NEW in Version 3.1.0 is support for an external CAT program such as Ham Radio deluxe to control the TX / RX functions, including the CW I'der, in the Equalizer software. See Help File under Serial Port Setup.

There are advantages and disadvantages to using CAT commands vs a full featured sound card interface with the RoMac 10 Band Equalizer software.

One big advantage of using CAT commands, is that many radio amateurs already are using their computers with software such as Ham Radio Deluxe. You will still be able to use a radio control program such as HRD on the same serial port by setting up a pair of virtual ports (See help File under "Virtual Ports")

The second advantage is the interface between the sound card and your radio, is as simple as an isolation transformer between the sound card and the Microphone input on your radio. (See here for a sample) , optionally a cable from the speaker output to the Line In on the sound card, and cabling a Microphone to the Mic In on the sound card. (or a USB microphone)

One disadvantage is that the "Rig Interface" mode of the software is not available, although many users will not find this is a problem. Version 3.1.0 and later, will support the "Rig Interface" mode correctly when keyed from an external CAT program.

The software supports the following radios, Icom 746, 746 Pro, 756 Pro, 756 Pro II, 756 Pro III, 7000, 7200, 7600, and 7800.
Yaesu FT 450, FT 857, FT 897, FT 920, FT 950, FT 1000, FT 1000MP, FT 2000, and FT 9000. All Kenwood and Elecraft.
If your Icom radio is not listed, select (Ic - Other) in setup, and supply the correct radio address.

The Elecraft radio's have a built in sound card audio "In" on the back of the radio and a Line out. Most other radios have a fixed receive audio out on one the Auxiliary connections on the back of the radio. See here for Icom 7200 and 7600 radios...

If your radio is not listed, please email us with the type of radio and we will do our best to add the radio to the list of supported radios. One requirement to support the radio, is the radios CAT commands must support an option to ask the radio if its in the transmit or receive mode for the CW I'der to be operative.
