Why internal tuner is bypassed immediately after tuning is started on Kenwood Transceiver?
If the internal tuner is bypassed immediately after tuning is started on your Kenwood Transceiver, adjust the antenna system to lower the SWR.
Why Kenwood Transceiver has poor receive sensitivity?
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.
What does 'HELLO' message mean on Kenwood Transceiver during transmission?
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.
What to do if Kenwood Transceiver does not respond to key combinations?
If your Kenwood Transceiver isn't responding correctly to key combinations or control adjustments, ensure you are following the procedures precisely. Check if the Frequency Lock function is ON and, if so, switch it OFF by pressing [MENU/ F.LOCK] for 1 second. If problems persist, perform a Partial Reset, and if necessary, a Full Reset.
How to unlock frequency on Kenwood Transceiver?
If you cannot change the frequency on your Kenwood Transceiver, the Frequency Lock function or Lock All function may be ON. Press [MENU/ F.LOCK] for 1 second to turn the Frequency Lock function OFF. The “ ” icon should disappear.
Why can't I transmit with my Kenwood Transceiver?
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.
Why attempts at controlling the Kenwood Transceiver with the computer have failed?
If attempts at controlling the Kenwood Transceiver with the computer have failed, check the cable and cable connections. Use the same parameters in the terminal program and the transceiver. Check Menu No. 56.
What does “TEMP–HI” message mean on Kenwood Transceiver?
If “TEMP–HI” appears and “CHECK” in Morse code sounds on your Kenwood Transceiver, stop transmitting and let the transceiver cool down for a while.
What to do if AT does not finish successfully on Kenwood Transceiver?
If the AT does not finish successfully on your Kenwood Transceiver adjust the antenna system to lower the SWR.
Why are received signals unintelligible on my Kenwood Transceiver?
If received signals are totally unintelligible on your Kenwood Transceiver, select the correct modulation mode by pressing [MODE] or [MODE] for 1 second.
