Transmitting, Microphone gain, 4 operating basics – Kenwood TS-870S User Manual
Page 29: Selecting transmit power, Transmit carrier level

For more specific procedures, refer to instructions for
each mode in “COMMUNICATING” beginning on
page 29.
MICROPHONE GAIN
The MIC gain control must be adjusted any time the
SSB (LSB or USB) or AM mode is used without speech
processing. Set the MIC gain control so that the ALC
meter reads within the limits of the ALC zone at all
times. When Speech Processing is used, the
microphone gain is fixed as shown in the table below
regardless of the MIC gain control setting.
The MIC gain control has no affect in FM mode. Menu
No. 61 (FM MIC) switches the microphone gain
between low (L) and high (H) in this mode.
Refer to specific procedures in “COMMUNICATING”
beginning on page 29.
4 OPERATING BASICS
TRANSMITTING
Methods for transmitting include the following:
•
Press [SEND].
•
Press and hold down Microphone [PTT].
•
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.
<<< (9L) >>>
Refer to sections in “COMMUNICATING” beginning on
page 29 for detailed explanations for transmitting.
Note:
You cannot transmit while the internal antenna tuner is
presetting {page 49}.
SELECTING TRANSMIT POWER
It’s 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 the TS-870S, it is possible to change
output power while transmitting.
To change your output power, turn the PWR control
counterclockwise to reduce power and clockwise to
increase power. The PWR scale on the Front Panel
meter provides an indication of your output power in
watts while you are transmitting.
TRANSMIT CARRIER LEVEL
The CAR control must be used for adjusting the carrier
level for CW, AM, and FSK modes. The control also
adjusts the Speech Processor output level when this
function is used in the SSB mode. In general, set the
CAR control so that the ALC meter reads within the
limits of the ALC zone. If the carrier level is set via the
computer interface, the position of the CAR control on
the Front Panel is ignored. After turning the CAR
control, the control becomes active again.
