Why isn't VOX working on my Kenwood TH-D74A?
- TTyler WeissSep 5, 2025
If VOX is not functioning on your Kenwood Transceiver, the VOX gain settings are likely too low. Try adjusting the VOX gain.
Why isn't VOX working on my Kenwood TH-D74A?
If VOX is not functioning on your Kenwood Transceiver, the VOX gain settings are likely too low. Try adjusting the VOX gain.
Why can't I recall memory on my Kenwood TH-D74A Transceiver?
If memory cannot be recalled on your Kenwood Transceiver, the recall method may be set to [Current Band], and the displayed frequency band's frequency hasn't been registered. Change the recall method to [All Bands] or register data in the memory channel.
Why doesn't pressing MR display memory channels on my Kenwood TH-D74A Transceiver?
If pressing [MR] on your Kenwood Transceiver doesn't display memory channels, it's because nothing is registered in those channels. You'll need to register data in the memory channels first.
How to make the scan function resume on my Kenwood TH-D74A?
If the scan function on your Kenwood Transceiver doesn't resume after stopping, the scan resume method is probably set to Seek. Change it to Time (Time-Operated) or Carrier (Carrier-Operated).
Why does the scan function stop immediately on my Kenwood TH-D74A?
If the scan function on your Kenwood Transceiver stops immediately, the squelch threshold level is likely open. Adjust the threshold level to an appropriate setting.
How to turn off reverse on Kenwood TH-D74A Transceiver?
If you cannot set Reverse to OFF on your Kenwood Transceiver, it's because Shift is set to ON, which would put the frequency outside the allowable band. Set Shift to OFF first, then set Reverse to OFF.
Why is the transmission output decreasing on my Kenwood TH-D74A?
If the transmission output decreases or "H" is blinking on your Kenwood Transceiver, temperature protection may be active, automatically reducing the output. Turn off the power or remain in the receiving state until the temperature decreases.
Why is the Kenwood TH-D74A Transceiver display blinking during transmission?
If the display on your Kenwood Transceiver blinks during transmission, the battery voltage is likely low. Recharge the battery pack or replace the AAA alkaline batteries.
Why can't I adjust the frequency on my Kenwood Transceiver?
If you cannot adjust the frequency on your Kenwood Transceiver, it might be because the Programmable VFO has been configured. Try reconfiguring the frequency of the programmable VFO.
How to fix Kenwood TH-D74A when it cannot use repeater?
If you're having trouble using a repeater with your Kenwood Transceiver, ensure that Auto Repeater Offset is set to ON. Also, verify that you have the correct tone frequency, shift, and offset width configured.
