Its most likely was programmed with a rx but no tx. Meaning it can recieve but not transmit, you can fix this with the programing software.

Cannot transmit, getting a constant tone while holding talk button and transmit light not coming on, any help?


Check the headset jack. There may be something inside causing a short. also, the CLS has an audio tone out button. Be certain you are not pressing it as you push the PTT button. The PTT is odd on this radio, it is the top BIG rubber button on top FRONT. Many customers get this confused with the tone transmit button.

I have this Kenwood TK-2107 .... when the ptt button is depressed the transmit led lights up but it does not transmit. Why is that, any good tips?


The output transistor could be bad. the Xmit relay could have burned contacts or is not operating at all.

Will not Transmit.Display Indicates "release mic button" and radio buzzes


The PTT button is probably stuck and your radio is already transmitting.
PTT = Push To Talk

Can't transmit signal. Only get a 2 second beep when I push the transmit button


You have a poorly charged or bad battery. It takes more power to transmit than to receive. Usually the first thing you lose with a low, bad or poorly charged battery is transmit.

Try a known good battery in the radio. This should solve the problem. If not, check your battery contacts, as you may have one which is bad or not making good contact.

Clean your contacts with a pencil eraser to assure good connection with the charger.

Best regards.

Tk 2200 ptt button not working. when the button is pushed, the light come on momentarily then goes off


Hi Benjamin,

Kenwood TK-2200. The light comes on when you press PTT button, indicates you are transmitting.

The light goes out when you release the PTT button, if itgoes out during transmission, but your message gets through to your contact, then I don't see the problem.

If the light goes out during a transmission and you are still able to communicate, Don't worry, be happy, it's just a minor glitch with the light, no the radio.

As you haven't given me the details that I have guessed for you, I hope I have been helpful.

Cheers,
Peter

Makes loud tone when pushing ptt button


The ptt switch or circuit is not disconnecting the audio circuit. Open the unit up and check the wiring, interconnect plugs for something shorted not canceling the receiver audio.

Makes loud tone when pushing ptt button


If it's a distinct "tone" like 1000Hz, it's probably mis-programmed. Check www.mods.dk. You may find a manual there.

Kenwood TK370N UHF FM HANDHELD RADIO


By keeping the PTT button pushed, if you get a rapid beep and the red led is blinking, sounds like a bad battery. Batt voltage is a nominal 7.5v. anything lower than 6.25v and the low battery beep starts. A rapid beep, and no red led blinking, an error in the transmit freq.
