The IC-R7000 is an older radio, there is also a newer model TRANSceiver called the IC-7000. I presume you have the "older" receiver?

Scancat-Gold supports the Older IC-R7000, but it's not known yet about the IC-7000 mobile transceiver.

Connection to the computer would require a CT-17 RS-232 interface, which is available from ICOM Dealers for about $125.00. AND.... You would need our Squelch Detect Adaptor which is $29.95.
