Why isn't VOX working on my Kenwood TH-D75A Transceiver?
- NNicholas ReevesSep 6, 2025
If VOX does not function on your Kenwood Transceiver, VOX gain settings may be too low. Adjust the VOX gain.
Why isn't VOX working on my Kenwood TH-D75A Transceiver?
If VOX does not function on your Kenwood Transceiver, VOX gain settings may be too low. Adjust the VOX gain.
Why can't I turn off reverse on my Kenwood TH-D75A?
If your Kenwood Transceiver's Reverse cannot be set to OFF, Shift may be set to ON. Setting Reverse to OFF in this state would set the frequency outside the allowable frequency band. Set Shift to OFF, then set Reverse to OFF.
Why can't I use a repeater on my Kenwood Transceiver?
If your Kenwood Transceiver's repeater cannot be used, Auto Repeater Offset may be set to OFF. Set Auto Repeater Offset to ON. Also, the tone frequency/shift/offset width may be incorrect. Select a proper tone frequency/shift/offset width.
Why is my Kenwood TH-D75A Transceiver not turning on with battery?
If your Kenwood Transceiver's power isn't turning on with a Li-ion battery pack or AAA alkaline batteries, it could be due to a low battery voltage. Try recharging the battery pack or replacing the AAA alkaline batteries with new ones. Alternatively, the Li-ion battery's protective circuit might be activated. To resolve this, remove the Li-ion battery, reinstall it, and then try turning the power on again. Note that when both DC IN and the battery are connected, turning off the power of DC IN may restart the transceiver. This is not a malfunction.
Why aren't memory channels showing on my Kenwood Transceiver?
If pressing [MR] on your Kenwood Transceiver does not display the memory channels, nothing may be registered in the memory channels. Register data in the memory channels.
What to do if most keys don't function on Kenwood Transceiver?
If most keys on your Kenwood Transceiver do not function, Key Lock may be enabled. Cancel Key Lock.
Why is the display blinking on my Kenwood TH-D75A Transceiver during transmission?
If your Kenwood Transceiver is blinking on and off during transmission, the power voltage is likely low. Recharge the battery pack or replace the AAA alkaline batteries with new ones.
Why won't my Kenwood TH-D75A 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).
Why won't the frequency change on my Kenwood Transceiver?
If your Kenwood Transceiver's frequency does not change when rotating the [ENC] control, Key Lock may be enabled. Change the type of Key Lock or disable Key Lock.
Why does the Scan function on my Kenwood TH-D75A stop immediately?
If your Kenwood Transceiver's Scan function stops immediately, the threshold level of squelch might be Open. Adjust the threshold level to an appropriate level.
