six operating modes: PA/FM/AM/USB/ LSB/CW
20. BAND SELECT SWITCH: This switch is allow the user to
select the desired band.
21. SQUELCH CONTROL: This control is used to control or
eliminate receiver background noise in the absence of incoming
signal. For maximum receiver sensitivity, it is desired that the
control be adjusted only to the point where the receiver
background noise is eliminated. Turn fully counterclockwise, then
slowly clockwise until the receiver noise disappears. Any signal
to be received must now be slightly stronger than the average
received noise. Further clockwise rotation will increase the
threshold level which a signal must overcome in order to be
heard. Only strong signal will be heard at a maximum clockwise
setting.
22. RF POWER: This control is used to adjust the RF power output
level you want in AM or FM transmission.
23 VOLUME CONTROL: Permits you to adjust the listening level
when receiving.
24. COARSE/FINE CONTROL: The "COARSE" control adjusts
the frequency ±5.0KHz in receive and transmit. The "FINE"
control adjusts the frequency ±1.5KHz in receive only. This
comes in handy when tuning in someone who is "OFF" frequency
compared to everyone else.
25. PHONE JACK: Accepts a plug from a headset of 4 to 32 Ohm
impedance.
