Powered up & inserted a bent component lead into the Dits & Ground - OK. The same on the Dash & Ground - OK! Plugged the paddles back in & it worked OK.
OK, so what happened there? ////////////////////////////// This is very similar to my experience building K1 #2476 last month. First try with the paddle resulted in strange behavior - can't recall the exact details, but very similar to your experience. After I unplugged and re-plugged a time or two all was well. I also vaguely recall a similar phenomenon when K2# 3777 was built. It almost seems like a micro-controller initial startup hiccup. I'm guessing the notoriously spooky key jack may have had some debris, poor mechanical alignment, stiff contacts, etc. I was particularly careful when soldering the key jack to the board - just enough heat to flow, but not melt the flimsy plastic housing. I've experienced more than one failure of these (both K1 and K2 key and headphone ) jacks so I always keep a spare on-hand. Both rigs are woking A-OK (at the moment) but I do try to limit the in-out cycles as much as possible to delay the inevitable jack failure.
