How to unlock frequency on Kenwood TS-870S?
If the frequency cannot be changed on your Kenwood Transceiver, it is likely that the Lock function is activated. To resolve this, press [F.LOCK] to switch OFF the function.
What to do if Kenwood Transceiver has poor receive sensitivity and S-meter is full scale?
If your Kenwood Transceiver is not receiving signals or the receive sensitivity seems poor, and the S-meter is reading full scale, it could be due to the RF gain control being set too low. To resolve this, turn the RF gain control fully clockwise.
What to do if Kenwood Transceiver does not function normally after switching on?
If your Kenwood Transceiver does not function normally after switching on the power, for example, no digits or incorrect digits appear on the Display, here are some possible causes: 1. The input voltage is outside 13.8 V DC ±15% (11.7 to 15.8 V DC). Correct the input voltage. Use a step-up transformer, if necessary, to raise the input line voltage to the DC power supply. Or, use a 12 to 16 V battery. 2. The microprocessor has malfunctioned. Review "MICROPROCESSOR RESET". After understanding what data will be lost, do a Partial Reset. If the problem remains, do a Full Reset.
Why can't I transmit with my Kenwood Transceiver?
If you cannot transmit using your Kenwood Transceiver even when you press [PTT], or transmissions result in no contacts, consider the following: 1. The microphone plug is not fully inserted into the Front Panel connector. Turn OFF the power, ensure the microphone connector on the Front Panel has no foreign objects in it, then plug in the microphone connector. Secure the connector with the locking ring. 2. The Transmit Inhibit function is ON. Switch Menu No. 27 (TX INH) to OFF. 3. You have selected CW or FSK instead of a voice mode. Press [LSB/USB] or [FM/AM] to select a voice mode. 4. The filter for Digital operation is selected. Switch Menu No. 19 (PKT.FIL) to OFF. 5. The wrong antenna connector (ANT 1/2) is selected. Press [ANT] to select the other antenna connector.
Why does my Kenwood TS-870S Transceiver have low transmit power?
If your Kenwood Transceiver exhibits low transmit power, it could be due to: 1. The MIC gain control and/or CAR control being set too low. Increase the MIC gain control and/or CAR control clockwise depending on the mode being used. Review the appropriate section of the "COMMUNICATING" chapter for the mode being used. 2. Poor antenna system connections causing high SWR. Check antenna connections. Confirm that the antenna tuner is reporting a low SWR.
Why is my Kenwood TS-870S Transceiver not responding correctly to button presses?
If your Kenwood Transceiver does not respond correctly after you press button or key combinations, or turn controls per instructions, the following could be the reason: 1. Procedures are not being followed precisely. Review "WRITING CONVENTIONS FOLLOWED". 2. The Lock function is ON. Press [F.LOCK] to turn OFF the Lock function. 3. The microprocessor and its memory need resetting. Review "MICROPROCESSOR RESET". After understanding what data will be lost, do a Partial Reset. If the problem remains, do a Full Reset.
Why won't Memory Scan scan a specific channel on Kenwood Transceiver?
If Memory Scan will not scan one of the stored channels on your Kenwood Transceiver, and the desired channel is NOT locked out, it means that with Group Scan selected, the channel you want to scan is in a different group. To resolve this, select All-channel Scan by switching OFF Menu No. 66 (GRP.SCAN), or change to the group that contains the memory channel that you want to scan. Group changes are done by pressing Mic [UP] or [DWN].
Why doesn't RIT/XIT control affect receive frequency on Kenwood TS-870S Transceiver?
If the RIT/XIT control has no affect on the receive frequency of your Kenwood Transceiver, it means that the Receive Incremental Tuning function is switched OFF. Press [RIT] to switch ON the function.
Why does Kenwood Transceiver show "HELLO" message when transmitting?
If you are attempting to transmit with your Kenwood Transceiver and the "HELLO" message appears, and the Receive mode is restored, it could be due to: 1. The antenna not being connected correctly. Check the antenna connection and correct as necessary. 2. The antenna not being matched correctly with the transceiver. Reduce the SWR of the antenna system. 3. The input voltage being outside 13.8 V DC ±15% (11.7 to 15.8 V DC). Correct the input voltage. 4. An inappropriate DC power cable being used. Use the provided or an optional DC power cable.
Why doesn't the linear amplifier operate with my Kenwood TS-870S?
If the linear amplifier does not operate with your Kenwood Transceiver, it could be due to: 1. The LINEAR Menu setting being incorrect. Set Menu No. 51 (LINEAR) according to instructions in "INSTALLATION". 2. The REMOTE connector wiring being wrong or faulty. Inspect the REMOTE connector wiring and correct it.
