Sometimes when I power up my K3 with my YCCC SO2R Box powered down, the K3 comes up in ERR KEY mode, disallowing transmission and other functions. Usually, powering up the SO2R Box and power cycling the K3 clears the problem. I assumed (erroneously, it turns out) that I had an issue with an indeterminate state on the key out line from the SO2R Box. But the principals at YCCC remind me that those circuits are opto-isolated and quite determinate, even when the box is powered down. They also note that with a recent release of K3 firmware, similar problems are being reported with other keyers connected. They suspect that this old error message may have an additional, new meaning in a recent firmware release, perhaps related to rx/tx timing. I'm not sure, but it has happened frequently in recent weeks, sometimes in the middle of an operating session. It is incurable when I am operating remotely until I visit the site and twiddle key lines. Once it happens, it doesn't clear itself through remote power cycling or anything else I've tried. Any ideas here?
