Hi,

Initially and the simplest probably would be to use the units without enabling the CTCSS or any form of encoding (turn this feature OFF). In the meantime, will check the specs and post if anything concrete comes up.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

SOURCE: can you give me any

Hi,

At the onset, basic tools and equipment would include (but not be limited to):

  • basic electronic tools & equipment (side cutter, screwdrivers, soldering station, DVM);
  • a dummy load wattmeter;
  • frequency counter;
  • RF Voltmeter;
  • SWR meter;
  • variable regulated power supply;
  • AF/RF signal generator;
  • Spectrum Analyzer (would be nice but not a necessity).
A copy of the service manual or at least a schematic diagram with voltage readings would be very helpful. Repairs would involve sectoring the handheld into:
  • logic/controller circuitry;
  • RX section;
  • TX section;
  • built-in power supply/regulator circuitry.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

SOURCE: changing a radio case

The TK272G is just like any other handheld it is just a matter of taking the radio apart and remembering or make notes of what you did. Start with removing the knobs on the top of the radio and then remove any screws that are under the battery compartment the radio should easily slide out of the case by using a screw driver at the bottom of the radio. Slide the scewdriver between the radio chasis and the case and the radio chasis should lift out. be careful not to bust the rubber seal O-Ring that may be between the radio chasis and the case. the rest should be easy for you to do. the key thing for you to do is take your time and remember the steps you have taken and reverse them when putting the radio back together.

Have a great day!

SOURCE: i have a kenwood tk-272g and the keys are locked

One of the keys has been programmed as the lock button. you will have to experiment by holding each button for a couple of seconds until you hear a tone that tells you the radio is unlocked.
On the one I have for our fire and rescue it is the < button but it could be any of the four on the front or the two on the side below the talk button.

Kenwood tk-272g radio wont transmit


This is commonly a sign of a bad or poorly charged battery. Check your charger, battery and battery contacts. Clean contacts with a pencil eraser. Try recharging the battery, making certain the radio is turned off while on the charger. If this does not solve the problem, try swapping batteries with a known good unit. If the swapped battery solves the problem, you know you need to replace your battery and/or charger.

If the problem remains with the swapped battery, you know you have a radio problem. In this case, you will need to look at the battery contacts on the radio, where the battery meets the radio and see if you see a problem there. OR a problem with how the battery fits to or in the radio.

If it is a radio problem, you may need to see your local Kenwood dealer for assistance.

Best regards.

I have a TK-280 and when i put it on the charger the red charging light comes on the starts flashing red after about a min. I am on the fire dept. where i live and kinda need it charged up. I wanted to...


  • Couple things this could be.
  1. First thing is to make sure the radio is seated properly in the charger and that all the contacts are making contact and not dirty.
  2. The other thing this could be is that the battery is bad. Or in the least the capacity for the battery is extremely bad and not reliable.
  3. If the contacts look good and it's sitting on the charger proper than you will need to get another battery pack. Sorry.

  • Hope this helps and thank you for using FixYa.

Flashing light


the problem may be the batteries. When the batteries get old and won't charge or if a battery needs recharging the kenwood radios TX/RX LED will flash untill the problem is resolved.
