Hi
     On a  related topic, I believe that I may still have a DB 25 to DB 9
adapter plug if anyone is interested in it.

God bless,
Mark

Subject: off topic dectalk expresses

Thanks to ka9jcp, both of my dectalks are working again.
The mystery of the 12 volt supplies is very interesting.
12 volts is 12 volts is 12 volts.  Plugs are plugs are plugs, but the plug
on the dectalk supply has a longer center conductor than the standard plug
of the same circumference.  The center pin on a standard 12 volt supply
wouldn't meet the center pin of the jack on the body of the dectalk express.

The outside of the round plug feels to be the same length.
Who knew!!!
