Heathkit did release a kit to change to grid block keying and it was
available (same kit) for both transmitters.  In the instructions Heathkit
states "...this strictly optional..."  It involves drilling a hole in the
front panel to install a push button switch and installing a terminal strip
on the chassis.  if there is no push button on the upper right side of the
panel then the grid block optional modification is not installed.  A copy of
the Heathkit instructions for the modification  is on Glenn Zook's (K9STH)
web site.The Antique Radios forum is a wonderful resource. This modification
has not been discussed there yet.
