I need to know how to do a swing kit on my rci 2980. Please help thanks

SOURCE: radio has no modulation

probably a final is out.

SOURCE: need wireing diagram for a rci 2980 to tug8 mic

Here is what I have: If the Tug 8 is a 4 wire cable,1/shield 2/white 3/red 4/black 5/N/C 6/N/C
If the TUG 8 is 6 wire cable,1/shield & blue 2/white 3/red 4/black 5/N/C 6/N/C .The reason I gave two diagrams is I can never remember if the 8 or the 9 is 4 wire cable.Also if your radio keys up when you plug mic in reverse the black and red.Good Luck and take care!

SOURCE: The s-meter goes down scale when I am modulating.

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.

SOURCE: rci 2980 no modauliton on am/lsb/usb/fm.but good

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.

SOURCE: RCI-2980 NO MODULATION

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..... [email protected]
