You say "new to me" ... did the previous owner of the MK II use it with
an Icom transceiver and install the "ICVOX" jumper documented at number
8 on page 9 of the microKEYER II Users Manual?  Did you follow the
Users Manual information in "Preparing microKEYER II for Use" on pages
8 and 9 of the Users Manual?

Icom transceivers have a *bidirectional* PTT signal (HSEND) on the
ACC jack and installing the ICVOX jumper connects PTT_2 on the DB37
*and* PTT IN to the HSEND signal.  That jumper must be removed for
use with transceivers from other manufacturers.
