LEVEL DIAGRAM

To

 make measurements in the AF section, connect

the AC level meter

. (ANT input: -53dBm, 1kHz FM,

3kHz DEV (WIDE))

In the RF section,use 1000pF coupling capacitor

.

(The display shows the SSG input value required to

obtain 12dB SINAD without local level.)

AG is set to the MIC input becomes 3kHz DEV at

1kHz MOD.(WIDE)

To

 make measurements in the AF section, connect

the AC level meter

.

In the RF section, use 1000pF coupling capacitor

.
