  johntranAug 22, 2025
  If your Kenwood Transceiver doesn't power on, ensure the DC power supply is switched ON and the power cable is correctly connected with the right polarities (Red: positive (+); Black: negative (–)). Check the power cable for any faults and make sure all connections to the DC power supply are secure. Also, inspect the power cable fuse; if it's open, find the cause, fix it, and replace the fuse with a new one of the specified rating.

How to improve SSB audio quality on Kenwood Transceiver?
- S
  Susan GarciaAug 30, 2025
  If the SSB audio quality on your Kenwood Transceiver is poor, with high or low audio frequencies missing, select USB or LSB for the mode. Adjust the DSP filter width by pressing [FIL/ NAR] and turning the MULTI control. Ensure Noise Reduction is OFF by pressing [NR] until the NR function turns OFF, and Beat Cancel is OFF by pressing [BC/ CW.T] until the BC function turns OFF.

  Kendra KennedyAug 28, 2025
  If you cannot transmit with your Kenwood Transceiver, even when pressing Mic[PTT], or transmissions result in no contacts, ensure the microphone plug is fully inserted into the MIC connector. Turn off the power first, check the MIC connector for obstructions, and then firmly plug in the connector. Verify that the Transmit Inhibit function is OFF by changing Menu No. 55 to OFF. Confirm that a voice mode is selected by pressing [MODE]. Adjust the settings in Menu No. 20. Select the correct antenna connector by pressing [ATT/PRE/ ANT1/2] for 1 second.

What does 'HELLO' message mean on Kenwood Transceiver during transmission?
- J
  Joseph SanchezAug 26, 2025
  If your Kenwood Transceiver displays the 'HELLO' message and reverts to reception mode when you try to transmit, check the antenna connection and correct it if necessary. Reduce the SWR of the antenna system. Ensure the input voltage is within 11.7 to 15.8 V DC, or use a 12 to 16 V battery. Use a DC power supply with a current rating of more than 20.5 A at 13.8 V DC; for the TS-480HX, two DC power supplies are required to transmit.

Why Kenwood Transceiver has poor receive sensitivity?
- C
  Crystal HamiltonAug 25, 2025
  If you're not receiving signals or the receive sensitivity seems poor on your Kenwood Transceiver, first, turn the SQL control counterclockwise. Ensure the Attenuator function is off by pressing [ATT/PRE/ ANT1/2] until “ATT” and “PRE” disappear, and release the Mic [PTT]. Also, check if the correct antenna connector (ANT 1 or ANT 2) is selected and the preamplifier is on.
