Re: [Elecraft] K1: Inp Menu Item Pdn Only Allows Dits
I can guess at 2 possibilities - one is that there was something sticky on the shell of that mono plug which adhered to the wiper in the paddle jack - it only takes a bit of something like the adhesive from electrical tape to do that. The second is that somewhere along the dash signal line, you have a bad solder connection that made contact when it was touched. If you have trouble again, I suggest checking the schematic for everything connected to the dash signal (including connectors) and re-flow the solder. 73, Don W3FPR MGFoster wrote: I turned on the K1 & tested to see if the problem still existed - it did.

Re: [Elecraft] K1: Inp Menu Item Pdn Only Allows Dits
I'm in the process of building a K1, I'll be sure to check the key jack carefully. I guess it would be best to wire the straight key, which is all I use for now, to a stereo plug anyway. 73 de Joseph Durnal NE3R On Thu, Feb 14, 2008 at 11:22 AM, crstrode <[EMAIL PROTECTED]> wrote: > > MGFoster Wrote: > I turned on the K1 & tested to see if the problem still existed - it > did.

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.

[Elecraft] K1: Inp Menu Item Pdn Only Allows Dits
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 I changed my Inp from Pdn to Hnd to test out my hand key. When I changed back to Pdn only the Dits side responds. The Dah side doesn't produce anything (yes, the paddle works outside the K1). While in Hnd mode I plugged in my hand key with a mono jack. When the key was closed a continuous tone was generated. I figured out that the mono jack was shorting the ground and Dah poles in the stereo jack, thus producing the continuous tone. So I changed the Inp menu item back to Pdn while I assembled a stereo jack for the hand key. That's when I discovered the paddle's Dah was not recognized. Could I have shorted something in the keyer circuit?
