Set the AG so that the microphone socket input is 3kHz
deviation at 1kKHz modulation.
The data communication
connector
input level is 3kHz
deviation at 1kHz
modulation
for 1200bps and 2kHz

Note 4:
The transmit frequency is 145.0 or 435.0MHz.
The HI/MID/LOW switch is set to HI.
The measurements with the power meter, except for the
ANT connector, are the values with the APC off.

Note 1:
The 12dB SINAD levels were plotted using a standard
signal generator through a 0.01pF ceramic capacitor at
each point from the RF to the first IF.

Note 2:
The AF levels were measured with an AF voltmeter when
the -73dBm

signal
modulated by a 1kHz modulation frequency and a 3kHz
deviation was received and the AF output was adjusted to
0.63V/8Q by the AF VR.
