Hi Jim, thanks for replying.
I am running the latest firmware and I do have VOX delay set in CW mode. However the 'bug' appears to only affect keying with external keyer, and works fine with the internal KX3 keyer.
Slightly annoying as I prefer to use my old CMOS superkeyer to anything else because I am familiar with it and like its timing.
