Speaker when receiving a transmitiion, the built in speaker sounds muffled and distorted at any volume. Other than volume, is there an adjustment that I can make? If not, can I purchase a replacement speaker for this unit?

Re: speaker

I would like to help because I have about 10 of those radios, and one by one the speakers are binding up just like yours did.

However, the speaker is built into the frame of the radio and the Manufacture does not sell replacemt parts for them. In addition, there is really not enough room to mount a replacement speaker of similar dimensions, and I am would be quite capable of doing it myself if that was possible.

I hate to face the fact that my radios have seen better days unless I want to use a speaker mic and I don't because the extra cost, size and weight are not practical to save radios that I can replace with new for just a bit more.

They were great radios, and Motorola should be ashamed that they don't make after market speakers. I'm sure they just want to sell new ones to us.

By the way there are no 'WIRES" to the speaker, it makes contact with the board terminals when you re-assemble the radio.

Re: speaker


There are no other controls to adjust the volume or tone settings of the audio output.
On speaker replacement, most TalkAbout speakers are not difficult to replace. They are however a challenge to purchase. It might be easier to purchase an off the shelf speaker of same dimensions and construction or those of comparable brands (Icom, Kenwood, Yaesu, Uniden). The only factor to be considered is if the replacement speaker will fit the confined space at the back of the front panel.
Alternately, you can just use an external speaker/microphone rather than purchase a replacement internal speaker, opening the unit up and do some minor soldering.
If even with a replacement speaker and/or an external one, the issue remains, it is possible that the unit has an internal electronic fault in the audio amp, demod, IF stage(s).
Hope this be of help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

BPR40 Receiving a static reception when someone is talking

Several things need to be checked. Fully charged battery. Antenna, make certain it s tight and unbroken. Wiggle the antenna while receiving, if reception improves, it is the antenna or the antenna jack. Then wiggle the on/off vol switch, same thing, if reception improves, it is broken or needs to be resoldered. Then I check the speaker. Speakers gather metal particles, as they get more and more, the speaker distorts and it sounds like static. Use a powerful magnet, run it over the speaker grill and see if anything comes out. I put plastic wrap on the magnet for easy cleaning. It could still be a bad speaker. Last, I check programming. All of this is done at our shop regularly and I suspect most radio shops follow the same procedures, maybe in a different order. Post if this helps or not.

Why does my volume not return to normal levels after using a motorola headset? Is there a way to return the unit to factory settings?

the volume control for the headset is typically the same one you use for the phone. plug the headset in again & use the volume control to increase/decrease volume as you require, remove the headset and use the same volume control to increase/decrease the volume on the device..

Check if it has an earphone jack if it does try plugging an earphone into it If you have audio through the earphone jack then the switch in the earphone jack could be bad or the speaker could be open this would be an easy repair. You might have a broken wire to the speaker. other causes could include cold solder joints bad volume control, bad audio amp, bad transmit receive switch etc

This could be one of a variety of problems:
1. Bad speaker
2. No receive
3. You are on an unprogrammed channel
4. You have a bad volume potentiometer (dead spot in the on/off/vol)
5. Another internal issue

Try going to monitor mode and see if you can hear the white noise typical of being on monitor. If not, you could have problem 1, 2 or 4.
Try adjusting the volume and see if the radio works at a different volume level. If so, you have a problem with the volume pot.

Best regards.

Permanent RX on Binatone 750

RX simply shows it's in receive mode, to check that the speaker is not faulty plug in an earpiece, if that is clear then you know the speaker needs replacing. Chris B-R

Have to use rf gain control to control volume. no control or very little with af gain control. ft101ee

RF gain is not used to control volume. It's used to adjust the sensitivity of the radio. If you have a station nearby that's very strong that you wish to listen to, turning down the RF gain will help reduce distortion and/or interference. The control for Volume is "AF Gain" (Audio Frequency Gain). You want to use it to set the volume level.

The audio on one radio is muffled. How can I fix it?

The problem is likely one of two things: 1) something is covering the speaker holes, or there is debris in the holes or 2) you have a bad speaker.

FYI: This radio is a repairable version of the TalkAbout closely related to the business model CP100. You can send it to a repair facility to have it repaired. (Typically around $69) You can google CP100 repair to find a Motorola shop capable of the repair, if needed.

Sound cuts out


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.
