Bring it to a cb shop and ask for a bench check, or ask a trucker to hook it up and check it out.

Motorola BPR 40 will transmit,but not receive through the microphone. Works fine as a handheld


You may have one of three problems: Your audio accessory jack is bad, you are using the wrong mic for the radio, or your mic is bad. Try the mic on a known good BPR40 and if it test good, if so, your BPR40 with the problem needs a new audio accessory jack. (Repair is available for this model.) We have found the BPR40 will only work properly with the remote speaker mic designed for it, despite some other Motorola mics appearing to fit the jack. Construction grade mic PMMN4013 is a good option, as is the lightweight PMMN4077.

Low outgoing transmission volume


Check to see your radio and the other radios are the same as to narrowband and wideband. A narrowband channel spacing radio will talk more softly to other radios which remain on the older wideband channel spacing. In the USA, all radios (with a few exceptions) were required to change to narrowband by Jan. 2013.

Another problem which commonly occurs comes from something (tape, sticker or debris) covering the mic hole on the transmitting radio. Look at the face of your radio and try to determine where the mic hole is, and then check it for obstructions.

Lastly, you can check the setting of your Mic Gain on radios equipped with this user programmable feature. Generally this setting offers the numbers 1, 2, or 3. Experiment to see which setting is best for your voice type.

Best regards.

Where does the charger plug in??


Did you recieve a manual with this radio? It usually states where the charger plugs into...

As my experience with other handies like this recalls, it should take the charger in either the mic or ear jack... (provided there are not any other jacks meant for the charger)

Best way is to obtain a manual from the supplier if you want to make 100% shure!

Regards,

Johan

Transmit button on the lapel mic will not key the radio


Two things which come to mind, one would be if the PTT on the remote mic is bad/defective, second would be you are plugging the audio device in with the radio turned on.

If your remote mic is failing, the PTT is a repairable item, as is the cord on most models.

ICOM IC-A6 Feedback type interference


The problem is caused by the microphone preamp in the headset demodulating the AM transmission. Sordin MSA headsets also have the same problem. What you require is a headset with no electronics in it and a dynamic microphone.

Radios comparable?


First, select the radio frequency band which would best suit your needs. (ie: VHF, UHF or 900 MHz) If you are talking in and around concrete and brick you would want to select the UHF or 900 MHz.

Second, with your frequency band chosen, narrow down the field of radios which have the features you like. (ie. number of channels, amount of wattage, text messaging, or plain jane, etc.)

Third, compare apples-to-apples. If you decide a 1 channel, 4 watt UHF radio would suit your needs, compare all brands with this criteria.

Fourth, look at the MIL SPECs of the radios you've selected. This will tell you much about their durability. (Some of the low cost radios will show up as lacking in this area.) The MIL SPECs are available for every radio on their product literature, and most likely on the internet.

Fifth, look at the size and weight of the unit. A radio might look great on paper, until you find out it is the size of a brick.

Sixth, look at repairability. Once your radio is out of warranty, is it repairable, and at what cost.

Seventh, look at battery, antenna and belt clip replacement costs. In two years you will need to be replacing those rechargeable batteries.

Hopefully, this will get you started. If you have questions, repost here, or talk to a radio dealer or two. IMHO most schools use UHF 4 watt models, or the newer 900 MHz (license-free) digital radios with success.

Sound cuts out


Hi,

It would seem that your volume control is spotty. A short term repair would be to spray the inside with electronic contact cleaner while rotating the volume control. Of course the best solution is to replace the component.

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.

Instructions on how to change channels on TECHNIKA MODEL TA-13


Basic Instructions for Technika Model TA-13

On this model there are 7 buttons:
Left to Right these are:

PTT, Push to talk on lh side as screen faces you.
Power/Menu
Scan
Call
Down
Up
Torch Light (on rh side)

Assuming you have used the power button to turn on the radio, the default channel after installing the batteries is 1 or else the last channel to be used.

Press the power/menu button once-briefly, (the current channel will flash for about 10 seconds.) Then use the Up and Down arrows to change channel. Wait for the remaining few seconds and the radio will return to normal operation.

Press the menu button twice, the letter H or L will appear and can be altered by the Up and Down keys to change the power level of the radio. I think this is transmit power which may help you avoid infuriating local taxi companies. Switch back to High power when you're about to go out for the night and need a ride.

Press the menu button three times. This will turn off Squelch control and make a terrible din. Not terribly useful unless you want to pick up a really weak signal (or find out where the taxi driver has taken your neighbour.)

An easy way of finding a channel is to press and hold the Scan button and then the device will rotate through the available channels looking for a signal. When someone transmits, the scan will pause and you can capture it by pressing the PTT button for a second or two. I have found this helpful in pairing my radios with other sets, or picking out channels that work with friend's radios.

Finally, Volume control is really simple, just up and down when not in any other mode.

I had the instructions, which I think included a mention of all available channels I'll scan and post them if ever I find them. hope this part helps though.
