ICOM C-IV Interface

The following ICOM CI-V circuit has been constructed to connect the ICOM radios to a computer via the RS232 port. The power is supplied directly from the COM port on the computer. (No Batteries to buy or replace!) I am working on software for an ICOM 746 radio at the moment. The software will allow for command line processing. (For example, you can click an icon on your desktop and have your radio jump to a specific frequency, etc.) If anyone would like me to set the software up for another model, please send me an email and supply me with the interface commands (this would be located in the user manual for the radio).
