Transmit/receive indicator doesnt turn off on one of the handsets, so that it receives white noise for a period of time after someone talks. Does anyone please know how to turn it off? Thanks.

Not familiar with this particular radio but it should have an eliminator code. Try setting an eliminator code on both radios, ( they must use the same code on each channel) if you want to talk between the two. If there is a "MON" ( montior ) button, try pressing and holding it in until you hear a confirmation beep.
Hope this helps you.

Kenwood Protalk tk-3200U8P will receive, but not transmit. When talk button is push a loud beep will sound. Any suggestions?


Assuming it is programmed correctly, it is a weak, undercharged or bad battery. Transmit takes a lot more power than receive. A beep or no transmit, even if the Transmit light comes on can still mean the battery condition described.

I cannot set QT filltering on..why?


Here are the instructions from the manual:

To transmit to a radio that has QT noise filtering turned on:

1. Select the same channel and Interference Eliminator Code as the other radio.

2. Press 'musical note' button to send a call tone. This allows your voice to pass through the QT

noise filter on the receiving radio.

3. Press the PTT and speak normally.

Note: If you skip step 2, the beginning of your message may not be heard on

the receiving radio.

For a 30-second period, starting after the last transmission, all transmissions
received on the selected channel and code will pass through the QT noise filter.

Also, your QT filtering will NOT work if you are in scan mode.

The ACTUAL problem is your rechargeable batteries have most likely depleted over time, and since it takes more batterie power to transmit than to receive it can appear that your batteries are fully charged and you can be receiving but due to the batterie it will be unable to transmit

In order to reset the radio, power on while pressing both volume buttons (+ and -) together with the PTT (speak) button, until you year a high-pitched tone.

But I have found that the "stuck on receive" problem is related to the battery voltage: non-rechargable AAA or incorrectly charged batteries can give 0.2-1.0V above the nominal voltage. Try to leave the radio on for a few hours or replace some of the four AAA batteries with slightly exhausted ones and see if that helps.

What you are describing indicated the "code" is not set the same on both radios. Check your frequency, interference code eliminator and Qt filter (if any). All the settings must be identical between the two radios. If you are still having issues, set your code and Qt filter (if any) to zero (off) and then try it. Lastly, check your batteries. Bad or poorly charged batteries can cause transmit issues, as it takes more power to transmit than to receive.

Motorola T5420 Transmit Problem


Here are some troubleshooting thoughts:

1. Is your battery indicator showing at least 2-3 bars? (Battery Note: Your rechargeable batteries may fail due to setting without use for a long period of time. They need replaced every 12-14 months usually. A good tip is to charge them once a month to keep the chemical in the battery active.)

2. Check to see your Qt noise filter is shut off. Refer to page 22 of the owners manual. It is possible you have some radios set to Y and others to N. To assure good communications you should set all of them to N.

3. With your radios set to interference code zero, place your radios one at a time in scan mode, while you transmit/talk on one individual radio. See if any of the radios receive. Do this with each radio individually to see if you are transmitting at all. NOTE: This test will determine if you have any ability to transmit. If you do not receive any sound on the 3 radios setting in scan mode, the individual radio you are testing will not transmit.
