Finally got the interface to work with the Radio File which Jim sent to me. Wouldn't work at 19200 baud as ZL3TE said he had his working but when I set the radio (Menu>Set>Connectors>CI-V>9600) and DX4Win (File>Preferences>Radio Baud Rate 9600) it started working. 73, Dan, N8VV N8VV at arrl.net N8VV at aol.com
