BULLETIN # 42
MODEL: TS-180S/SM-220
SUBJECT: TS-180S IF output #2 Level Change for SM-220

TS-180S owners who desire to operate an SM-220 for IF output display will
require a wiring change to the IF unit X48-1240-00.  No additional parts
and no adjustments are required.

Remove R77, 470 ohm, and replace with wire jumper.  Remove R78, 56 ohm, and
replace with old R77.  The 56 ohm resistor is not used.

With AGC on, gain should be adequate for about a 3/4 screen display.
