OPERATING BASICS
TRANSMITTING
Methods for transmitting include the following:
²
Press
[SEND]
.
²
Press and hold down Mic
[PTT]
.
²
Connect a key or keyer paddle, select the CW mode,
press
[VOX]
to switch ON the Break-in function, and
close the key or keyer paddle.
For a detailed explanation on transmitting, refer to
sections in °BASIC COMMUNICATING± beginning on
page 20.
Note:
When CW, FSK, or AM is selected, the transmit carrier level is
automatically adjusted according to the selected mode.
SELECTING TRANSMIT POWER
It³s wise, and required by law, to select the lowest
transmit power that allows reliable communication.
Reducing power lowers the risk of interfering with others
on the band.
On this transceiver, it is possible to
change output power while transmitting.
1
Press
[PWR]
.
²
The current transmit power appears.
2
Turn the
MULTI/CH
control counterclockwise to
reduce power and clockwise to increase power.
²
The displayed transmit power changes.
°
SSB/CW/FSK/FM:
Transmit power can be
changed from 5 W to 100 W in steps of 5 W.
°
AM:
Transmit power can be changed from 5 W to
25 W in steps of 5 W.
3
Press
[PWR]
again to complete the setting.
Note:
The transmit power can be separately selected for the AM
mode independent of the other modes.
MICROPHONE GAIN
The microphone gain is finely adjustable in the SSB or
AM mode.
A different level can be selected between
when the Speech Processor {page 32} is ON and when
the Speech Processor is OFF.
1
Press
[MIC]
.
²
The current microphone gain level appears.
The
default is 50.
2
Press
[SEND]
or press and hold Mic
[PTT]
.
²
°TX± appears.
3
SSB:
While speaking into the microphone, adjust
the
MULTI/CH
control so that the ALC meter reflects
according to your voice level.
AM:
While speaking into the microphone, adjust the
MULTI/CH
control so that the calibrated power meter
slightly reflects according to your voice level.
4
Press
[SEND]
again or release Mic
[PTT]
.
²
°TX± disappears.
5
Press
[MIC]
again.
For the FM mode, set the microphone gain by
accessing Menu No. 17 {page 17} and selecting either
°L± (low) or °H± (high).
Note:
When using the optional MC-90 microphone in FM mode, select
high microphone gain.
The microphone sensitivity is low in FM
mode and this may cause insufficient modulation.
When using a microphone that has an amplifier, be careful that
the output of the amplifier is not too large.
