Greg, WB2BIN I use DXbase with the IC-7610. Set DXbase to IC-7600 and change the IC-7610 CI-V address to 7Ah which is the same as the IC-7600. Baud rate of 9600 seems to work the best so set the IC-7610 for 9600 and DXbase for 9600. Word: 8, Parity: None, Stop Bits: 1 No check mark in DTR, RTS or CTS 73, Keith K4XP
