Question about Kenwood FreeTalk XL TK-3101 (15 Channels) 2-Way Radio

1 Answer

Kenwood 3101 wired backwards.

Thanks Freetek, It was simply my poor judgment. I use these radios as a bike to bike (motorcycle) communications. I use a Autocom battery adapter that hooks to bike power. Were I went wrong I was connecting power to a tank bag. I reversed the wires on "power out" and plugged the first radio in. It did not work, and like a dummy I grabbed my spare and you can guess what happen next. In the end, two bad radio's. Thanks Smitty

It would be nice to use the bike electrical system for power and not worry about battery juice. The TK 3101 is PC programmable so you could try and put in PL Tones.
They are like a way to filter radio signals out but that is different from the whine you are probably getting over the wiring.

SOURCE: Kenwood TK 3101 two way radio problem

Most devices that can be operated from external supplies have a diode across the the power jack that will short the source if the polarity is reversed.
Since this is a pretty small part without much chance of surviving the current available from a cigarette lighter socket, the only hope you have is that the fuse almost always found in these 'adaptors' will blow before the diode fails.

If the radios will not operate from batteries, I'm afraid they are badly damaged.

It son't hurt much now if you open the case and check near the power jack for burned parts. The diode(s) probably aren't there at all any more since they are commonly capable of no more than an amp or two and the typical fuse in those car adaptors is 5-10 amps, enough current to cause the diode to explode before the fuse blows.

I don't know where you reside, but in the US there are many sources for low-cost digital multimeters (<$20 US) that would have prevented your problem simply by checking the polarity of the jack before plugging it in.
I don't think the lighter was at fault; I believe the adaptor was wired for a particular item, just not for your radios.
It's always chancy to use a power source only because the plugs match.

Most devices have a small symbol molded into the plastic near the power jack showing which polarity input is correct.

SOURCE: FreeTalk 3131 compatible with proTalk radios?


Hello Christian,

Some of the Kenwood ProTalk series radios may be programmable by the dealer to operate in the 462-468 MHz range used by GMRS and FRS radios. However the radios are not FCC approved for those channels and do not comply with requirements for FRS and GMRS radio equipment.

You are going to be better served by picking up a FreeTalk 3131XLS like your friends have. In terms of style and features this radios is very similar to the ProTalk but is type approved for use on GMRS.

Best Regards,
Ken

Hello hiyya1311,

I would really recommend against painting the radio. Paints may contain chemicals that can be harmful to electronics. Even if you could get the outer shell of the chassis completely removed and separated from the electronics components before painting (which is likely not a small undertaking), the paint can still emit fumes for a long time after drying and those fumes could potentially contain corosive chemicals.

As far as cleaning, most manufacturers recommend thay you simply wipe the outside of the unit off with a damp cloth when cleaning is needed. (NOTE: a damp cloth NOT a wet one.) Most radios are gasketed against dust so the inside of the radio should not require any cleaning. Should the grooves along the outside of radio require extra attention you can use a dry (or damp, if necessary) cotton swab. (Again, not a wet cotton swab.) Do not use cleanser or chemical cleaning products on the radio under any circumstances.

If you have experience in disassembling electronics devices and feel comfortable in your ability to take the unit apart and put it back together, instructions on doing so (including diagrams) are in the manufacturer's service manual which is available from Kenwood Communications. You can contact the manufacturer on their website at http://www.kenwoodusa.com/Communications. However this should rarely (if ever) be required for cleaning the unit and may void your warranty if you still under the warranty period of the radio.

Best regards,
Ken

Kenwood TK-3101 is sensitive to Motorcycle RF


After a lot of experimenting, I decided to try powering the Autocom with a 9v battery and that fixed the issue. Evidently, the power from the bike was dirty - I'll have to filter the power line, find a different place to tap into or remain battery powered.
