make measurements in the AF section, connect the AC level meter

(ANT input: –53dBm, 1kHz FM, 3kHz DEV (Wide 5k).)

In the RF section,use 470pF 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 5k).
