I attempted to interconnect my Icom 756pro, the MicroHam DigiKeyer and a recently purchased Palstar AT-Auto autotuner. They all communicate using the Icom CI-V protocol. The 756pro and the DigiKeyer work fine together as does the 756pro and the AT-Auto. When all three devices share the CI-V line, there appears to be a conflict between the Digikeyer and the AT-Auto. The AT-Auto will randomly start to retune even though it had previously tuned at that frequency and placed the setting into its memory. While using Ham Radio Deluxe, the band edge warning will chime at frequencies that the AT-Auto had previously stored in its memory. Using the Icom CT-17 level converter does not resolve this issue. Any words of wisdom? Thanks. Joe W8DCQ
