Question about Kenwood TK-3100K2 (2 Channels) 2-Way Radio

1 Answer

TK 3100, No communication, codes check out OK

I have added an additional TK-3100 2 channel radio, to the many others I use.
I have changed and confirmed the frequency and tone to match the others but, it will not communicate on either channel with any of them.
Was wondering if there is anything else I needed to do?

Thank you for you assistance.

Try one of the side buttons to see if you can hear squelch noise. If so, hold it in then talk on an existing unit. If you can hear it, then the squelch code is wrong, if you still can't hear it, then the frequency is wrong or the unit is defective.

How do you change the channel on the AXU4100

Here is a link to the user guide, where you will find the available built-in frequencies, and instructions:

You can also take your radio to a Motorola dealer and have them program it (custom) using Motorola software and cable designed for this style radio.

It could be as simple as enabling a private line code (PL code) in the radio. You may not need/want to change frequencies. Adding a PL code would block out other users on your frequency. You would not hear them, despite them still being there.

Best regards.

I bought additional kenwood tk 2100 radios and they are not sending the signal to my existingones. The fcc numbers and interior tk numbers are the same. How to I get them on the same frequency.

To change the channel frequencies on your TK2100, simply press and hold the PTT switch ("talk button") and Monitor key, then turn the power on. Now press the PTT switch again. The light should change from orange to red and a beep should sound. Next, adjust the channel switch to the channel you wish to program. Now simply press the PTT button to choose between 4 to 8 possible frequencies, depending on your model.
You can find the manual and frequency graphs here:

Hi Tucaraca.

With the radio OFF, switch to CHANNEL 1, press the SQUELCH and the PTT at the same time. Turn ON the power switch while keeping the PTT and SQUELCH until the LED indicator turns RED.

Release the buttons and then press the PTT to CHANGE the FREQUENCY.

Press the PTT once each time until you get to the right frequency you desire. The 8 standard frequencies are as follows: 464.500, 464.5500, 467.7625, 467.8125, 467.8500, 467.8750,467.9000 and 467.9250 MHz. Once you get to the frequency you use, wait a few seconds and listen for the confirmation tone. Each frequency has a different confirmation tone so take note in case you need to program a second radio.

After you hear the confirmation tone, press the SQUELCH to confirm, and then press the SQUELCH again to lock the new frequency. Wait until the LED turns off, then switch off your radio.

Same procedure for CHANNEL 2.

WARNING: You must be legally licensed to use any frequency on any PLMRS such as the TK-3100 series. You must also apply for FREQUENCY COORDINATION and submit FCC form 601. FCC can impose steep fines and imprisonment if they catch anyone using an unlicensed radio on a controlled frequency. Visit FCC.GOV for more information.
