Why isn't my Kenwood TH-D75E Transceiver showing as a removable disk?
If the Kenwood Transceiver is not displayed as a removable disk even though it is connected to a PC via a USB cable, the USB selection setting may be set to "COM+AF/IF Output". Set the USB selection setting to "Mass Storage".
Why is the display on my Kenwood TH-D75E Transceiver darkening?
If your Kenwood Transceiver's display is dark, it may be due to the temperature of the transceiver rising. To resolve this, turn OFF the power supply or remain in the receiving state and place the transceiver in a cool place.
Why won't my Kenwood Transceiver power on with DC power supply?
If your Kenwood Transceiver is not turning on when using a regulated DC power supply or cigarette lighter socket, the issue might be a faulty power cable or a bad connection. Check the cable for any abnormalities and ensure the polarity is correct. It's also possible that the power cable fuse has blown out. If this is the case and the fuse blew for reasons unrelated to the transceiver, replace the fuse after repairing the cause.
How to fix no sound from Kenwood TH-D75E Transceiver speaker?
If your Kenwood Transceiver shows no sound from the speaker, even with the volume up, check if the sound has been muted in Volume Balance; if so, set it to a non-mute volume. Also, ensure the squelch is not closed by lowering its threshold level toward 0. Furthermore, check if CTCSS or DCS are enabled and, if so, set them to OFF. Finally, if the transceiver is paired with a Bluetooth headset, disconnect it to restore sound to the speaker.
Why is my Kenwood TH-D75E transmission output decreasing?
If your Kenwood Transceiver's transmission output decreases or "H" (high power) is blinking, the temperature protection might be activated, automatically reducing the output. Turn OFF the power supply or remain in the receiving state and wait until the temperature decreases.
Why is GPS reception poor on my Kenwood TH-D75E Transceiver?
If the built-in GPS receiver on your Kenwood Transceiver struggles to receive signals, the local circuit of the transceiver might be affecting the GPS sensitivity. Change the frequency in band A/band B, or change the frequency in use.
Why is speaker sound transmitting on my Kenwood Transceiver?
If the speaker sound is being transmitted on your Kenwood Transceiver, the headset with VOX function may not be connected. Connect the headset with VOX function, and then set VOX to ON.
Why are signals not demodulating properly on my Kenwood Transceiver?
If received signals are not properly demodulated on your Kenwood Transceiver, the signal format (Demodulation mode) settings might be incorrect. Try changing to other modes. Also, if the receiving sound is distorted in AM/SSB/CW, the receiving signal might be too strong. Set the ATT function to ON.
What to do if most keys don't function on Kenwood TH-D75E?
If most keys on your Kenwood Transceiver do not function, Key Lock may be enabled. Cancel Key Lock.
Why won't my Kenwood Transceiver resume scanning?
If your Kenwood Transceiver's Scan function does not resume scanning after stopping, the scan resume method might be set to Seek. Change it to Time (Time-Operated) or Carrier (Carrier- Operated).
