YOUR FIRST QSO

Note: Only those buttons and controls required to briefly try the transceiver are explained in this section.

qSet the following as specified:

¥AF gain control: Fully counterclockwise

¥RF gain control: Fully clockwise

¥ SQL control:

Fully counterclockwise

w Switch ON the DC power supply, then press and hold the [ ] (POWER) switch briefly.

¥The transceiver switches ON. Indicators and frequency digits should light on the Display.

AGC

USB

e VFO A should already be selected for receive and transmit as shown by the lit indicators in the [RX A] button and the [TX A] button. If not, press the [RX A] button.

r Increase the AF gain control slowly clockwise until you hear a suitable level of background noise.

t Select an Amateur band by pressing the [UP] or [DOWN] button.

¥First pressing the [1MHz] button before pressing the [UP] or [DOWN] button lets you step up or down in 1 MHz increments instead of stepping between Amateur bands.

y Select an operating mode by pressing the [LSB/USB] or [CW/–R]button.

¥Press the same button again to toggle to the second function on the button. For example, repeatedly pressing the [LSB/USB] button switches between LSB and USB modes.

u Turn the Tuning control to tune in a station. If no stations are heard but you have an antenna connected, possibly the wrong antenna connector is selected. Pressing the [ANT] button toggles between the Antenna 1 and the Antenna 2 connectors.
