[amsat-bb] Dual IC706 MKII-G operation

[Stephen E. Belter]

Tom,

You need one CT-17 or equivalent level converter.  I use the West Mountain Radio RIGtalk which is a USB serial port to CI-V interface.  Many people build their own (easy for an RS-232 serial port) or buy inexpensive converters from ebay.

The CI-V interface is an "open-collector" party-line.  You can parallel 2-4 Icom radios using Y-adapters, then connect it to the CI-V output of the CT-17, RIGtalk, or other similar interface.

Does that answer your question?

73, Steve N9IP
