External Clock for CW Mode
The CW mode clocks can be supplied from J9 (X16/X8/X4/X1) and J10 (X1) using external signal
generators. The manufacture default setup uses ON BOARD CLOCK, with which C154, C155, C156, and
C157 are installed. To switch to an external clock, these four capacitors must be uninstalled and
capacitors C49,C50,C52, and C53 must be installed. The following table shows the configuration for these
eight capacitors.
