To enter the second function of the [KEY] button press [FUNC] button and then
[KEY] to select and set the following options. Once adjusted using the main
tuning knob, press the KEY button again to exits the settings process.
Options:
CW Volume: sidetone volume setting
T800Hz: sidetone tone frequency setting
B500: CW receiving bandwidth setting (the default value is 500Hz) –
set to 300 if using the automatic CW decoder function.
SSB Voice Communication
Plug the lead from the hand microphone into the MIC port on the right-hand side
of the head unit. After inserting, the green indicator light on the hand microphone
will light.
1. Press the [MODE] button (< or >) on the top of the head unit to switch between
LSB and USB mode. Ensure you do not select U-D or L-D.
2. Use the second function (after [FUNC] button has been pressed) of the
[POW] button for the following settings:
1) MIC GAIN: set the level of the hand microphone audio
2) INPUT: select where the audio input comes from (the default is MIC and
this is required during voice communications).
3. A momentary press of the [POW] button allows you to set the output power
level.:
1) POWER: Set the required PEP output level (range is 1W - 20 W).
2) SWR THR: set the standing-wave-ratio protection threshold (default is 3:1).
If the radio sees an SWR over this value it will reduce power to protect itself.
4. After you have set the parameters above you are ready for SSB
communications.
■ The default hand microphone voice gain value is appropriate in most cases.
Watch the spectral display when transmitting and if you see extra lines above
and below the main audio trace, reduce the mic gain or move away from the
microphone until they disappear. Normally a setting of 10 is a good place to
start. You should see the TX power readings peak at the level you set. The
average meter indication will be lower. This is normal.
