(12) NB switch
Activates the noise blanker circuit which is effective in reduction of impulse
type noise (ignition noise, etc.).
(13) ANL switch
Activates the automatic noise limiter in the audio. The ANL will be effective
in reduction of atmospheric (discharge) interference.
(14) RF Gain switch
Selects RF Gain (receiver sensitivity) of the transceiver in 3 ways:
DX. In this position. The receiver section provides maximum sensitivity so
that it can pick up even weak signals.
Normally this switch should be placed in this position.
Mid. In this position. The receiver sensitivity is medium, and may be used
when you desire to pick only strong or fairly strong signals.
Local. In this position, the receiver sensitivity is minimum, and the receiver
will pick up only the strong signals. May be used when receiving strong
(close) signals which are causing overload in receiving sound.
(15) Meter
Serves to dual purpose
When receiving, this meter gives the relative strength of incoming signals
in `s` units. When transmitting, this gives RF power output in lower scale.
(16) Microphone jack
Accepts plug from the microphone supplied. The jack has a locating key in-
side and allows the plug inserted in only one way. Do not force the plug but
align key way properly onto the jack.
(17) Microphone
Supplied With transmit pushbar (PTT) mounted at the left side.
