Makes loud tone when pushing ptt button

My friends tk 280 was not receiving very well so he took the cover off to check the antenna connection. He said everything looked good so he put the cover back on and now when he pushes the ptt button the radio makes a loud tone. I asked him to check and see if the radio was actually transmitting by letting someone listen on another radio or scanner on the same frequency and he said that it is transmitting and you can also hear the loud tone on the other radio. This radio is used in our local rescue service so we need to get it fixed as soon as possible. Thanx for any help

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.

The antenna sheath on my Kenwood TK-3131 FreeTalk XLS is broken. Can this (spring) antenna be replaced? How to? My others screwed in.


The antenna is still available at E. Coast Transistor Parts 516-483-5742 in W. Hamstead, NY 11552. I just received two at $11.25 ea delivered for $30.45 total. (Part #: T90-1004-25). Very nice and knowledgable customer reps were happy to help me.

I,am just now working to install them so,I will have to get back on that part.

Carefully remove 4 internal(inside battery compartment) screws and two near top back and the front face will remove..BE CAREFUL WHEN SEPERATING BECAUSE SPEAKER WIRES WILL HOLD TWO HALFS TOGETHER WITH A LITTLE ROOM TO SEPERATE PIECES.

Pull off vol. knob, remove lock nut below. Carefully SEPERATE body, bottom first. Remove gold screw from board and black screw at antenna. Carefully remove antenna parts and final screw. REPLACE ANTENNA, screw down, replace board and black,and gold screws. Replace antenna locknut, rubber side covers over put button and side plugs. Replace 4 short screws inside batt. Compartment plus 2 long screw on top of back. careful not to,over tighten. Replace battery pack and cover.

First one took 30-35 min. Second took 20 min.

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.

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


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

Kenwood tk-280


The TK280 portable is a trunking/conventional two way. It does not support digital communication. There is no upgrade available short of a new radio. By the way...new digital radios are very pricey so be prepared to spend some $$$. Good luck.

TK 380 not transmiting


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.

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.
