Frequency Range
FM1/FM2 : 87.5 MHz to 108.0 MHz
FM3 :
65 MHz to 74 Hz
AM :
(MW) 522 kHz to 1620 kHz
(LW) 144 kHz to 279 kHz
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.
