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.

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.

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.

Mode CW, AM, FSK FM Speech USB/ Processor ON LSB Speech Processor OFF Adjust CAR Control? Yes No (Carrier level is fixed) Yes No 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. Mode (Speech Processor ON) USB/ LSB Transmit Equalizer ON Transmit Equalizer OFF AM Microphone Gain Fixed -28 dB -34 dB -34 dB 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.
