Hi!

I always imagined that I'd become trapped in an elevator somewhere, and
knowledge of CW would be the tool that got me out. That's never happened,
but neither is it likely.

The first time I had a heat pump installed here, I asked the company
installing it to teach me how to use the equipment. They agreed to do it,
but I was the one that observed hearing an A sent in code each time the unit
was switched on. Again, I was the one that observed hearing an N in code
each time the unit was switched off. When I explained that it was code, the
installer had no clue, saying they never heard anything. Granted, it wasn't
real loud in Desebels, but that wasn't needed, hi hi. The manual or user
guide that came with the deal made no mention of this feature, but Paula
picked up the pattern instantly though she has had no formal CW training. To
my mind, the A meant Active, and N meant not active. I couldn't find any
suggestion that engineers at Fugitsu planned this, but I always knew whether
anyone ever turned that heat pump on or off if I was in the room at the
time. A single letter told me what was most important. Hi hi.

73,
Dave

copied CW with a keyboard when I got my extra, and still can do it 
for fun. I don't wish to forget how. :)
never know! may come in handy some day.
