I’ve never done this myself, but my understanding is that CI-V is a multipoint protocol. I have an Icom CT-17 level shifter into four concurrent CI-V lines that are just paralleled, all at the same baud rate. You can do this less expensively with a few 3.5mm sockets wired in parallel. See the CT-17 manual and circuit diagram.
CIV is preferable to band lines in that the Icom exciter can provide freq info, not just band, and the KOA1500 ATU can preselect a setting before transmit. 73 de Dick, K6KR > On Jun 27, 2021, at 12:06, Kelly Jones <kjo...@virtualcohesion.com> wrote: > > I have been kicking around the idea of purchasing a KPA1500.
