Thanks to all who responded. I found the fix described in the TT Wiki
to be most helpful. I formed a small loop at the end of each lead of a
0.01uF cap, placed the outer pins of the header to the connector through
the loops and reconnected the connector. No soldering involved and the
keyer is now stable.
