Refer to sections in ÒCOMMUNICATINGÓ 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

ItÕs 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.
