[CQ-Contest] IC751A/AEA CK1 combo

I decided to dig up my old AEA CK1 Keyer (remember those?) to use with the
Icom IC751A that I have.  The internal keyer on the radio is nice but
doesn't do everything you'd like a "real" keyer to do.

For some reason when I plug it into the key jack on the radio, I get:

-- only dashes without even closing the paddles (2 conductor 1/4 plug)
-- alternating dots and dashes when I close either side of the paddles (3
conductor 1/4 plug)
(I was just trying anything I could think of...no difference if the
internal keyer was turned on or off.  Have always used the 2 conductor plug
mated with and RCA adapter as that's what comes out of the keyer.)

I'm obviously missing something here.  I've used the CK1 with a lot of
different radios in the 20 years I've had it, including a LOT of use with
an IC751 (no A.)  I'm guessing the internal keyer on the 751A is the root
of the problem.  The manual is useless.  Any clues?  I'm clueless.....
