About one year ago when I built a RockMite-40 and was about to try it I heard somebody calling CQ on 7040 kHz. I quickly plugged in my Bencher paddles to find that only one side was working and the other side didn't (new stereo 1/8" plug from R.S. was bad). Couldn't find my straight key right off (sorry, I had moved a couple of years before and still haven't finished unpacking yet). So, I quickly found another 1/8" plug which I clipped some wires to and tapped out my reply for my first QRPp QSO with the RockMite-40, from Allentown, PA to Wilmington, DE! This relates to the thread about a bad fist as well, as you can imagine. But I guess it wasn't so bad, or at least when I explained and appologized in advance to the guy in DE he must have given me great room for error, but was still able to copy me okay. I was horrified as it was the worst code I think I had ever sent! It was classic, though, to have a Morse code QSO by literally tapping two wires together.
