Thanks Joe W2JJT October 1, 2017 at 9:22 pm #3652 w8tamParticipant I use a Hardrock 50w amplifier with my LD-11. The radio keys the amp through the PTT RCA jack. I’ve used software to synchronize band changes, but have been unable to do it directly. 73, -Thom w8tam Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
