SECTION 2. CONTROLS2.1 FRONT PANEL CONTROLSMeter (1 on Fig. 5)The meter monitors five different functions. In the receivemode it acts as an S-meter. In the transmit mode itmonitors ALC (Automatic Level Control),- IP (platecurrent), RF (relative power output), or HV (high voltage).METER Switch (2 on Fig. 5)The meter switch determines what the meter will read inthe transmit mode. It switches to either the ALC, IP, RF,or HV.AGC/CAL Switch (3 on Fig. 5)AGC: Two different AGC time constants may be selected.Slow AGC is a long time constant and fast AGC isashort time constant.These positions select a 25 kHz crystal calibratormarker. The VFO position is used for calibratingthe matching remote VFO.CAL:MIC Microphone Connector (4 on Fig. 5)A four prong connector is used so that PTT operation ispossible with a suitable microphone.GROUNDCABLE {COAXIAL CABLEFig. 3 Antenna Connectionses 482 (feet)f= Frequency (MHz)PHONES Headphone Jack (5 on Fig. 5)This jack allows operation with 8 ohm headphones. Whenthe headphones are plugged in the speaker is disconnected.Main Tuning Knob (6 on Fig. 5)The main tuning knob operates the main tuning dial.Vernier Scale (7 on Fig. 5)The vernier scale is calibrated in 25 kHz divisions and itsrange is 0 ~ 600 kHz.Dial Reference Lines (8 on Fig. 5)These reference lines make accurate frequency readoutpossible in all three modes of operation.MODE Switch (9 on Fig. 5)This switch selects either USB, LSB or CW.AF GAIN, NB PULL ON, POWER OFF Switch(10 on Fig. 5)POWER OFF — With the switch in this position thetransceiver is turned off. Turn the set on by turning theswitch clockwise. 3AF GAIN — The volume of the received signal increasesMIC CORDAs seen from the cordFin A AAG
