cb radio

i have asked a simaler question before, i have purchest another danita 3000uk cb radio for spare or repair.there canot be mutch wrong with it , but i canot figure it out. problem is my mate lives 100 yards away from me.i can hear him transmit loud and clear,but when i transmit he tells me he can hear me keying the mic and i am making a good signal on his meter.but there is no audio at his end. i am also showing transmit and receive good signal on my metre, my reseive audio is good can anyone help............. THANKS.

Tried another microphone ?

Does the radio have a PA function, maybe switch to that and see if you can hear your own audio with the mic you are using, and another microphone ?

no the cb has not got a pa function , i have tried three other microphones. still have same problem. .................is there any thing else i can try........... THANKS.

I don't know anything about CB's, but if this a problem on all modes, then it's a circuit board issue.

thanks again daxi........... i dont know mutch about circuit boards.would not know where to look first on the board ,if someone told me where to look i could probably fix the problem, and what to look for.......... i can solder so thats one a good thing. any more imfo ,would be great .......... THANKS AGAIN BOYS.

hi dont know these radios very well . but is the mic gain set right !!

there is no mic gain on radio, or mic . thanks...porky.69

mmm doesn't make sense ... loose wire in the mike maybe ??

thanks again porky.69. i have just taken mic apart,checked the the wiering on plug and mic........ all ok. i wounder if there is a part on the circuit board that controls audio output,and if there is , on what part of the circuit board would it be. : THANKS.........

My radio prodding days are long gone, is the fault solid, ie the radio from cold shows the same fault after its been on for a bit.

I'd recommend asking over on the Transmission1 forums to be honest as there are people on there that may be better placed to assist.

i have had the radio on all day and still have same trouble.does not make sense , i know it is transmiting my mate said he can hear me pressing mic ,and signal shows on his radio,but no audio. .................. i cant understand this.tried everything i can think of

Any signs of damage on the circuit board ? any blown components ?

it might sound silly but is it a mike that needs a battery ?

there is no damage on circuit board............... i have tried four difirent mic raphones one with batteri, other three do not use batteries. still have same problem............... ITS GOT ME IM STUCK.

me to

Maybe it has a dodgy connection between the mike socket and the circuit board. Possibly a dry solder joint?

I take it most of the components inside are surface mount, is there any evidence of any of them having fallen off the board, as this can happen is they haven't been soldered on properly when the rig was built.
