    I HAVE NO IDEA. THE SELLER JUST TOLD ME IT HAD BEEN TUNED AND ALIGNED. I DOUBT THAT THERE MANY WHO COULD DO THAT. MOST SUGGEST THE FACTORY DO ALIGNMENTS. WISH I COULD GIVE YOU AN ANSWER, BUT I HAVE NO IDEA. POSSIBLY NO ONE HAS WORKED ON IT.

    THANKS FOR THE INFO. I'M SURE THAT YOU ARE PROBABLY CORRECT SINCE YOU WORK ON THEM. SEND YOUR EMAIL ADDRESS, AND I MIGHT JUST HAVE TO SHIP HER TO YOU AND GET HER ALIGNED. THANKS.

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 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..... poikaa@yahoo.com

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.

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.

Will not stay on 11 meter turn it off comes back on 10&12 meter will not transmit am or ssb recieve ok. rci 2995dx.


Hello janetsue, If this radio has the blue or green screen LCD face then this is a default that is built into the radio. It depends on how the radio was "converted" when it was bought new.
It will not key up on 10 or 12 because of the default. A little more info supplied would be real helpful,,,, Let me know, Mechanic
