In a future implementation, multiple receivers (a mix of R-71As and R-7000s) may see duty with each transceiver - all capable of being controlled via one CT-17. The aim was to use the -751A as my FT8 rig and the -71A as a second receiver, for monitoring other parts of the shortwave spectrum. I recently dragged one each IC-751A and R-71A out of storage to place in my main floor shack/home office.
It allows multiple radios to be connected together and computer controlled via a CT-17, or two to be directly connected for purposes of synchronized operation. Almost every Icom rig made since the mid 80s incorporates their CI-V computer interface.
