SECTION V OPERATION GUIDE |
PRE-OPERATION CHECK
Before you turn on the power switch, check the following:
1. Check to be sure that all cells and battery pack are in position with proper polarity. If an
external power supply is used, check for correct cabling.
2. Fully extend the rod antenna. If an external antenna is connected, fully retract the rod
antenna. Check antenna connection. |
3. Make sure the microphone or key is properly connected.
SSB OPERATION
The SSB has both USB and LSB; USB is used more commonly for 50 MHz band operation. |
SSB Receiving | |
1. Before turning the power switch on, set each switch and control as follows:
_ MODE switch | USB
VOLUME control | |
and POWER switch OFF (fully counterclockwise)
SQUELCH control |
and LOW POWER switch Fully counterclockwise (Pushed in is normal position.)
LOCK switch OFF (out) | |
RIT control Center (12 o'clock) position (or RIT switch OFF)
TS switch OFF (out)
LIGHT/METER switch S/RF (center position)
2. Rotate the VOLUME control clockwise. The power will be applied and the operation
frequency will appear on the frequency display. |
3. Rotate the VOLUME control clockwise to an appropriate sound level.
4. Rotate the tuning control knob to increase (clockwise) or decrease (counterclockwise) the
frequency. | |
NOTE: When the highest frequency (53.999.9 MHz, or 53.9984 MHz in USB mode) is
selected, rotating the tuning control clockwise will select the lowest frequency
(50.000.0 MHz, or 49.9986 MHz in USB). Rotating the tuning control counter-
clockwise beyond the lowest frequency will select the highest frequency.. |
The tuning rate in each mode is as follows:
| Mode | Frequency step Per single knob rotation
10 kHz 500 kHz
USB |
LSB 100 Hz 5 kHz-
5. Since the SSB signal has no carrier, no beat tone can be heard even when the signal is
received. Set the tuning control in position where the S meter has the highest indication
level so that the voice can normally be heard. An accurate 100 Hz step tuning rate permits
quick and easy tuning. | |
