Hello I want to make sure this is the cable I need for the ICT90A. This has been copied from RT SYSTEMS. http://www.rtsars.com/ RTS-01 Computer Interface cable for Icom HF Radios. This cable works with any Icom radio that can be controlled using the Icom CT-17 cable. The RTS-01 connects one radio to one computer. $35.00 Thanks! Just because you can not see the stars does not mean you can not reach for them.
