NOTE

' RF-SG is set to the lowest response possible on oscillo-
scope.

' The output level of RF-SG is made a loss by the dummy

so you should take into consideration the value of the
loss applicable to your case.

" Repeat TRACKING adjustment several times and con-
firm the reception of broadcasting,
