Adjustment:
1. Setting of SSG
Receiving frequency
: 1000 kHz
Percentage modulation : 30%
Modulation frequency : 400 Hz
Antenna input
: 74 dBuV (EMF)
2. Set the system as shown in 1., then tune to a
radio station.
3. Superimpose the pulse over signal to set
modulation of SSG to OFF.
4. Use a noise meter to monitor output. Adjust
VR201 to minimize the noise level.
