[Elecraft] External Keying Auto-Detect problem

[Bob Tellefsen]

I finally got my problems with N1MM Logger sorted out, only to find
that my keying adapter doesn't produce the expected results.

I have a pair of 1N4148 silicon diodes going from the Logger key line
to each of the dit and dah lines to the K2.  The cathode of each diode
goes to the common Logger keying line.  My paddles connect
directly to the dit and dah lines for paddle keying.  The K2 is set to
InP PdLn and works fine with the paddles.  If I put a closure on the
keying line from Logger, though, I get a continuous di-da-di-da-di-da-di.

If I set the K2 input to handkey, and connect the Logger key line directly,
it works just fine.

The K2 is suposed to detect simultaneous closures on the dit and dah lines,
and interpret that as a hand key input.  Not doing it so far.
When I turn on the K2, the firmware versions displayed are 2.03d and 1.07.

Anyone have any ideas on how to get this working?  Should I be using
Germanium diodes instead?
