Hi All,
Interestingly, the keying speed of the TCS has to be reduced on crystal
control or it chirps like crazy.

it's finest. Rob was certainly hammering those relays with the bug!  I
recall seeing somewhere that the ART-13 recommended maximum keying speed
was 20 WPM because of the response time of the vacuum antenna relay and the
other keying relays.  Have never tried using anything other than a straight
key on mine.
