Question about Uniden PC78ELITE 40-Channels Base CB Radio

1 Answer

I can't hear through my internal or external cb speaker

I just recently found out I can't hear any RX transmissions through my Uniden PC78ELITE internal speaker or my external speaker. Everybody at work can hear me talk and my needle moves when they talk I just can't hear them. I am at a loss. All connections seem to be tight but I wanted to know if it is something inside. I sodered my external speaker wires and replaced the mini jack hoping that was the problem but that didn't work either. Thank you for your time and I hope you can help

Can you hear static when the squelch is at minimum ?. If you can hear static then tere is nothing wrong with the audio system. If you are sure about the squelch, connect goosd speaker directly to the 2 wires coming from the main board bypassing the speker jack. if there is still no sound then the audio amp chip is defective. The audio amp can only be damaged if the output is shorted for a long period of time.

Uniden 40-Channel CB Radio (PRO505XL) "PA" acts like an extra external speaker!
because when you switch to PA it is because you are on the outside of your vehicle.When another party calls you ,you can hear them and then go to your vehicle flip it to cb and talk to your party.

I need a schematic for a uniden pc 78 elite cb radio
I will assume you have also looked for the schematic as a Cobra 29ltd which is the same radio----Check the internal speaker with a meter first and also examine the external speaker jack which will cut the inside speaker off.

Lastly a microphone with a broken wire in any area will kill receive audio.

I have a PC 78XL CB radio and it is on but cant hear nothing ,volume is turn up
Make sure squelch is turned down enough---if meter shows signal and no audio the internal speaker may be bad (plug one into external jack on rear of the radio).

If the radio transmits and shows it (or someone can hear when you xmit) the problem is in the audio circuit of the radio.

Check internal/external speaker AND SWAP THE MIC as a mic with a broken wire inside or open element as well can cause this.

Texas ranger cb tr-396FC \r\nhello, do not hear anything in the speaker and do not find any scheme or service manual. Yours sincerely
Is the speaker the internal or external one ? disconnect the external speaker then take a multimeter on ohms with sound and touch the pos and neg contacts . you will hear a beep ,now look at the meter and read what ohm reading you have.check to make sure you are on band mode and not pa . If you hear nothing add an external speaker which will over ride the internal speaker and see if you still get nothing. Now that you have confirmed this you may want to take it to a tech and have them fix it. And I did a google search and found a service manual for this radio .

Uniden pc78elite antenna light
What kind of antenna is it? Have you checked your standing wave? To do this process you will need a field strenth or a SWR meter to do it,would be cheaper to have it checked at Radio Shack or you can buy one,and do it yourself. Some radio antenna light come on when transmitting,....hope this helps....

Pc78elite won t transmit but receive is ok
Have the SWR's ever been checked on this radio when it was installed? where they over 2 or higher?

Most likely the final transmit transistor is bad from too high of an SWR.

Hi, This is a link to your old post re SWR 3....http://www.fixya.com/support/t180697-pc78_elite_cb As stated SWR 3 is too high, it should be 1.5 or lower. Fiberglass antenna are kinda notorious in setup and experience wise have not performed well or at all. Maybe you should try a different antenna (metal rod). Some good brands/models I have tried with very good results are K40, Hokushin, Comet, Oscar, Maldol, Daiwa. To check if you can receive, stick an ordinay length of wire ('bout 9' long) at the center of your radio's connector. RX should work (pls don't key the mic or TX).
