    • Attempting to enter a frequency that is outside the TS-870S frequency range causes an alarm to be generated. The entered frequency is rejected. • If an incorrect digit is pressed, restore the previous frequency by pressing [CLEAR], or [SEND], or Mic [PTT].

  • Page 29: Selecting Transmit Power, Transmitting, Transmit Carrier Level, Microphone Gain

    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.

    TRANSMITTING VOX (VOICE-OPERATED TRANSMIT) VOX eliminates the necessity of manually switching to the transmit mode each time that you want to transmit. The transceiver automatically switches to transmit when the VOX circuitry senses that you have begun speaking into the microphone. When using VOX, get into the habit of pausing between thoughts to let the transceiver drop back to receive briefly.

  • Page 52: Speech Processor (ssb/am), Changing Frequency While Transmitting, Transmit Monitor

    7 OPERATING AIDS SPEECH PROCESSOR (SSB/AM) The speech processor functions by leveling the large fluctuations in your voice when you speak. This leveling action effectively raises the average transmit output power resulting in a more understandable signal when operating using SSB or AM. You will notice that using the speech processor makes it easier to be heard by distant stations.

  • Page 53: Customizing Transmit Signal Characteristics (ssb/am), Changing Transmit Bandwidth, Transmit Bandshift, Equalizing Transmit Audio, Microphone Agc

    CUSTOMIZING TRANSMIT SIGNAL CHARACTERISTICS (SSB/AM) The quality of your transmitted signal is important regardless which on-the-air activity you pursue. However, it’s easy to be casual and overlook this fact since you don’t listen to your own signal. The following sub-sections provide information that will help you tailor your transmitted signal.

  • Page 54: Automatic Mode, Automatic Mode Boundaries, Using Automatic Mode

    7 OPERATING AIDS AUTOMATIC MODE Automatic Mode automatically selects the operating mode according to a set of frequency and mode data that you input. The purpose of Automatic Mode is for the transceiver to select the correct mode for you as you tune within a band.

  • Page 58: Adaptive Filters, Auto Notch (ssb), Beat Cancel (ssb/am)

    Only Auto Notch, or Beat Cancel, or Noise Reduction can be used at one time. They cannot be activated at the same time. Also, Menu No. 18 changes to its default setting when the TS-870S power is switched OFF and then ON again.

  • Page 59: Noise Reduction (ssb/cw/fsk/am), Setting Spac Time, Noise Blanker, Aip (advanced Intercept Point), Attenuator

    NOISE REDUCTION (SSB/CW/FSK/AM) Menu No. 13 (LINE.ENH) determines whether the Line Enhance function (an adaptive filter) or the SPAC filter is used. When using the Line Enhance function, switch Menu No. 18 (TRACK) to ON. The SPAC filter works better for reducing noise and is effective for eliminating various types of noise.
