Microphones are the most handled object with a CB radio and this is where it is most likely to find the problems. Basically a Galaxy radio in a base station box, and 3 out of ten develop problems, mostly power supply problems.
I would suspect the mic first. Best way is to use a different mic and see if the problem goes away. Next try the radio on an external DC supply or battery. Let me know what happens from there.....

Rci 2980 no modauliton on am/lsb/usb/fm.but good recived. and good output.on am.

is it steady output on AM with no modulation swing. then change the Audio transistor. SSB should work. they feed straight through to rf final. if no modulation on either mode, then check the mic, audio ic preamp.

Ranger 6900f-25 has no output

either the transmitter is grossly out of alignment or one or more of the new parts are already defective.
power = voltage X current. it's usually what happens when someone attempts to repair a piece of equipment like this by "swapping parts" while not in posession of the necessary test equipment and technical expertise.

The s-meter goes down scale when I am modulating. What causes this? THIS IS ON A RCI 2980 RADIO

the reason i saked is that if you turn the power all the way up it tends to reverse modulate. this happens because the power is using all the transmit voltage for the final and the modulation circuit is trying to use as much as it can so the radio is most likly out of alignment and needs to be realigned. its not that hard if you have the service manual and the correct equipment. i have a factory authorized shop and we do alot of realignments due to the cb shops tweaking the 10 meter radios.

RCI 2980 power adjust problem

VR16 is not the low power adjustment, it's the CW Tone.
As far as I can tell, there is no low power adjust.
Try a different resistance pot for the RF Power.

I would guess that you have a bad audio chip or a bad component in the audio circuit ( most likely the chip ). I am assuming, from your discription that the sound is muffled? If you are infact getting bleedover from other channels, you may have a bad crystal or a bad PLL Chip. I hope this has helped.
