    What all have you done to the radio up to now???

  • Kevin May 11, 2010

    Does the radio have an RF gain knob?  If yes, turn it to the maximum position (fully clockwise).

Have you measured reflective power? If it is 15 watts, then you have an antenna problem

Peak and tune a mini magnum 30 10 meter radio


You need schematics and a good peak reading watt meter. You can do damage if you don't have eqipment/knowledge.

Mini Magnum Radio not transmitting after Final Replaced


Not knowing what kind of equipment you have, its hard to say, but .10 watt? Sounds like the buffer or driver also got involved. Usually you get 1/4-1/2 watt to the driver on a stock radio. I would also check the bias resistors like you suggested. Also check for burnt foil around the final you replaced. Good just be a slightly damaged circuit. Let me know if this helps.

do you get any other sound from the speaker?
check squelch settings
does external speaker work?
If yes - internal speaker is bad

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.

The one that looks new but wont turn on, looks like the battery is dead, try swapping the battery from the other set that works and then try it. also try swapping the parts from the other sets and see if it works. Speakers dont fail so easily on two way radios.

Push to talk problem


Hi,

If indeed radio #1 has a mic problem, this may be confirmed by trying an external speaker/microphone plugged into the accessory jack. If still a no, then its not the mic but possibly the modulator circuitry. If there is transmit audio with the external mic and hence internal mic is defective, the unit would have to be pried open and the defective component replaced. The internal mic is normally an electrofet 2-3 terminal soldered to a shielded wire and physically attached to the front plate.

Alternately, another possibility is that radio #2 has its Interference Eliminator Code enabled/activated. This is indicated by the presence of small sized digits on the top right of display. If this is the case and no similar digits are displayed in radio #1, then radio #2 will not allow any received transmission to be heard. Along the same line of reasoning, if the code is activated on both radios signified by the presence of the 2 small digits, and radio #1 has a problem with its CTCSS (code) generator, then it would also prevent reception of radio #2. A way to verify this is by deactivating/disabling the Interference Eliminator Codes on both radios.

On certain occasion, it is also possible that radio #2 has a defective speaker. You should be able to verify this by plugging in an external speaker to the accessory jack of radio #2.

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

Good luck and kind regards.

Speaker Hook Up


Hi, Most if not all external speakers for 2way radios just uses two wires to 2 pins going to a mono baby phone plug. There are some models/versions that uses proprietary connector but very seldom. The connection is similar to a mono earphone except of course that instead of an earpiece, it uses a speaker/enclosure. Hope this be of some help/information. Post back should you need additional information and pls include brand/model of the radio. Good luck and kind regards.

Unexpected problem


I think you can have problems with the speaker, if you see the signal display working when you reiceve the VCO is working. If you could check (I dont remeber if this radio has audio connectors) external speaker. If this radio has an audio conector, this conector switches the internal and external speaker and could be dirt and is not switching to the internal spk.

to dissamble this radio you have to remove the face panel, under this face panel ( the blue one) you will find others screws. first of all try if you have an audio accesorie, with this earbund or head set the audio must be normal or the same quality than the other one, if is not, the radio need quilified service. Good luck Ernesto

I'm not sure about your particular model but many CB radios use the microphone push-to-talk switch to kill the speaker while the radio is transmitting. If you don't have the correct microphone or if the cord has a broken wire it can cause the radio to have no sound. Another possibility is that the speaker is bad. There is probably an external speaker jack on the back of the radio. You could try plugging a different speaker or even an earphone in the jack to see if you get sound there.
