Transmission; Audio Transmission; Cw Transmission; Adjusting Microphone Gain - Kenwood TS-890S Instruction Manual

4 BASIC OPERATIONS

Transmission

Audio Transmission

1 Press and hold the [PTT] key on the microphone or
press the [SEND] key.
The transmitting status is activated and the [BUSY/TX] LED
lights up in red.
2 Speak into the microphone in the normal tone and
loudness.
3 Release the [PTT] key on the microphone or press the
[SEND] key.
Doing so restores the receiving status.

CW Transmission

Performing the following steps when a key or paddle is connected
enables transmission in the CW mode.
1 Press [CW/ CW-R] to select CW mode.
2 Press [VOX] to enable break-in.
3 Operate the keyer or paddle.

Adjusting Microphone Gain

Microphone gain can be adjusted in the SSB or AM mode as
follows while referring to the ALC meter display.
1 Press and hold the [PTT] key on the microphone or
press the [SEND] key.
• The transmitting status is activated and the [BUSY/TX] LED
lights up in red.
2 Speak into the microphone in the normal tone and
loudness.
3 Turn the [MIC/PITCH] control to adjust the microphone
gain level.
Microphone gain is displayed as "MIC:nnn" at the top of the
screen. [nnn: 0 to 100]
.
When in the SSB mode
Turn the [MIC/PITCH] control while speaking into the
microphone. The ALC meter fluctuates according to the
volume level. Ensure that the maximum level does not exceed
the ALC zone during the adjustment.
When in the AM mode
Turn the [MIC/PITCH] control while speaking into the
microphone. Adjust in such a way that the PWR meter
fluctuates slightly according to the volume level.
4 Release the [PTT] key on the microphone or press the
[SEND] key.
Depending on the squelch level setting, the [BUSY/TX] LED
may light up in green or go off.
Speak into the microphone in the normal tone and
●
loudness. Make sure that your mouth is not too close to
the microphone and do not speak too loudly. Doing so
may increase the extent of distortion, thus causing
audibility to deteriorate at the receiving end.
To use a speech processor, refer to
●
Processor" (8-4).
Note that the output level tend to be larger when a
●
microphone with a built-in AF amplifier is used.
Microphone gain in the FM mode can be configured in
●
Advanced Menu [10] "Microphone Gain (FM Mode)".

Adjusting TX Output Power

Maintain a TX output power level that is as low as possible while
ensuring that communication can be carried out smoothly. Doing
so reduces the likelihood of interference with other stations.
The TX output power level can also be adjusted while transmission
is in progress.
Turn the [POWER] control to adjust the TX output
power.
Turning the [POWER] control to the right increases the output
level, while turning it to the left reduces the output level. The
selectable range varies with the band and mode in use as
follows.
HF Band
50 MHz Band
70 MHz Band (E type)

Fine Adjustment of TX Output Power

It is possible to alter the step size when the [POWER] control is
turned.
Configure in Menu [6-04] "Transmit Power Step
Size"
1[W]: Adjusts the TX output level in a step size of 1 W.
5[W]: Adjusts the TX output level in a step size of 5 W (e.g., 5,
10, 15...).
