CI-V can send frequency and status information that can be used by a remote antenna controller, rotor box, or coax switch connected to multiple antennas. In addition to controlling the radio, CI-V can connect to a variety of station hardware to facilitate in-shack or remote operation via a PC. You can use digital mode software such as Fldigi toĬontrol the radio using the computer and CI-V port. Take advantage of the CI-V system by retrieving frequency information to helpįill in log details. If you run a logging program that supports CI-V, that software may Memories on the radio, but you will need the appropriate programming software.īut there’s more–it’s not just a clone of your rigĬontrols.
On many HF radios, the CI-V system is also used to program the CI-V is also useful on radios where thereĪre multiple submenus in the menu system, allowing items to be easily changed Generally speaking, the more modern the radio, the The radio’s capabilities and what features the software writers included in the Will be shown on the PC’s screen via your software. Changes you make (volume, tuning, RF gain, etc.) Using a CI-V program and interface allows you toĬontrol your radio from the PC. Itself is between the radio and the software on the PC. The CI-V interface itself doesn’t do any communicating–it only provides theĬorrect voltage levels or protocol required by both.
I’ll also refer specifically to the IC-7300 for examples since it’s a well-known transceiver.Ī CI-V interface is a piece of hardware thatĬonnects the radio and the PC, allowing them to communicate with each other. To keep things simple, I’ll use CI-V to represent both CI-V and CAT interfaces since they essentially perform the same function. Radios because most operations are on channels rather than frequencies. CAT and CI-V are infrequently used on VHF/UHF
Same protocol across its many transceivers, while Yaesu generally wrote a new Each manufacturer typically implements its own version. However, manufacturers never settled on a standard You can find it on most HF and some VHF rigs manufactured since the 1980s, and its basic operating structure hasn’t changed much since then.
Other manufacturers such as Yaesu refer to this as CAT (Computer-Aided Transceiver). This is Icom’s name for its rig interface to a computer or to another rig. CI-V stands for Computer Interface V (V representing the Roman numeral for 5 ).
