Hi Jack, Thanks for joining in the discussion.
Before proceeding there is one typo that I made below. When I say, "when it is Band5=B6,", it should say "when it is Band6=B6," I have read your comments carefully but I am still confused. First, let me state once again: I have installed (I think, nothing is certain with this thing) the v1.6 (ACC) hex file and the configuration program dutifully reports that the installed version is indeed v1.6. Nevertheless, I have used the "Hold F4 while powering on" method to set the default configuration. My confusion with your comments is with the 6-meter case. My table below is reporting what actually happens with v1.6 firmware and the Band6 configuration changed as noted. The fact is there can be two different 6-meter responses. I can't see by looking at any documentation where one of them is a "default." I would be nice if the manual stated in plain English, something like, "If you connect the KRC-2 to a K3 via the AUXBUS the binary outputs A, B, C, D and the band sink/source outputs will be as shown in Table X, when CONFIG:AUX Band6=B6" "If CONFIG:AUX Band6=B10 then the respective outputs will be as shown in Table Y." I will make further comments to your other posting.
