BAND STEP
FM : 100kHz (Seek), 50kHz (Manual)
AM : 9kHz step
DUMMY LOAD
Exclusive dummy load should be used for AM
and FM dummy load,there is a loss of 6dB
between SSG output and antenna input. The
loss of 6dB need not be considered since
direct reading of figures are applied in this
working standard.
