RCI 2980 power adjust problem

I have a problem with the low power adjustment not adjusting. The high will. The radio works fine other than that but cannot use the rf power adjustment. I can bring the power [watts] down to 3 watts or so with the high and thats all. This radio was picked up fairly cheap and someone has had their golden screwdriver in it. have fixed several other problems. Are the adjustments the same as a 2980wx. Can't find a lot of info on this radio. I have vr 13 as high vr 16 low vr 14 mod adj. would appreciate any help.

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.

Make sure the output of the AC to DC power suppy inside the radio is between 12 and 14.4v, and hasn't been cranked up to 16v in the screwdriver expert's quest to put mo' axe in their co-ax.

Most probably, someone has removed a resistor or something on the main board in the never-ending quest for more wattage or modulation, and now the radio is out of alignment...

The main circuit board is a EPT 3600. The adjustments are the same as a 33 HML Galaxy. I have an RCI 2980 and have used these schematics to tune my cb with. Hope this will be of help.

S/rf is too high on transmit on my cobra 29 ltd bt


no matter what s/rf you are looking at it should not key much beyond an s-9 . vr 3 controls the meter. Key the mic and adjust it to s-9 then check you modulation.If you still think you need more then adjust vr 4 .

I just bought a used cobra 200 gtl dx im totally clueless to cbs could u tell me where all the controls and buttons should be



  • Hi, I can help.

  • I have uploaded a pic of the Cobra 200 and labeled each knob/switch with letters to reference.
  1. A) Noise blanker - When this switch is pushed the high pitched noises are canceled leaving a more natural sounding receive. Some like it some don't.
  2. B) High Power - This button adjusts the power output of your radio. Inside the radio the pots are adjusted for a low power setting and a high power setting.
  3. C) Roger Beep - This is a beep heard by the person you are chatting with at the end of your transmission.
  4. D) The 10+ KHz - This button when pushed jumps the frequency up 10 Kilohertz to help you better navigate frequencies.
  5. E) This is where you adjust how you are going to modulate. CW is for continuous wave or Morse Code. Unless you have a key don't worry about this setting. FM is for Frequency Modulation AKA the HAM bands. AM is for Amplitude Modulation. USB and LSB are for Upper Side Band and Lower Side Band respectively.
  6. F) is the band adjustment - Each band (A, B, C, D is a set of frequencies.
  7. G) is a dimmer and the SWR calibrate. To use the dimmer push the dim button in a rapid motion. To use the SWR calibrate side press and hold the dim/calibrate button and using the SWR knob on the right side of the radio (L).
  8. H) SWR/, S/RF - If this button is in the out position then your meter will swing as usual. Push the button in to measure SWR.
  9. I) is the volume and squelch. Volume is what is adjusted to how loud you want your speaker. Squelch you adjust to take out the unnecessary white noise.
  10. J) Mic Gain and RF gain - Mic Gain is how much gain you want to your mic. RF gain is how much of the receive you want to pick up.
  11. K) Is the fine and course adjustment that you clarify your frequencies with.
  12. L) You adjust the echo and the SWR with.
  13. M) is the channel selector.

Symptom:Buzzing or motorboating sound in either the transmit or receive.

RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.

Does anyone know the pod too turn for lowering the watts on my connex it is too high and i would like to turn it back also the modulation thanks


You have to adjust the high key first so make sure you're rf power is on high, hope you have a meter set it on the 20 watt scale, key up and turn vr 13
located in back of radio infront of where you're coax connector is until it keys around 12 watts, thats where most connex 33hp should be set,now go to low power and key adjust vr 16 right net to the otherone down to about 3 watts, now you can drive a liners. Mod is Vr 2 right below them two. whistle in mic and turn to get the mod you want.

I dont know were the adjustment nobs should be i just got this radio and dont know that much about the galaxy 959


There are little red dots on the edge of each knob. As a starting point, try these knob positions (starting from the knob on the left)..
Adjust volume as desired.
Adjust squelch all the way counterclockwise (no squelch).
Adjust mic gain so the red dot is at the 12 o'clock position.
Adjust mic gain so the red dot is at the 12 o'clock position.
Adjust light dimmer as desired.
Adjust RF Power with the red dot at the 12 o'clock position.
Ignore talkback and clarifier for now.
Now for the 5 little slide switches...
Set all of them to the middle position.
Now you should be able to operate transmit and receive.

This is a very good radio, but there are so many adjustment knobs that you can reduce its performance if you just blindly turn knobs.
After you learn how the radio sounds and works with these average settings, play with each knob, adjusting a little and see what it does for your particular antenna setup. Do some "radio checks" with other CBers and find out what your best settings are. Also read the owners manual for guidance on what each knob does...especially mic gain (too low and you won't be heard, too high and you'll be garbled) and RF Power (to little and you won't reach out very far, too much and you'll overload local listeners). This is definitely not a beginners radio. But it is a lot of fun and will enable you to learn a lot.

adjust the squeelch tuning, the antena is also a factor and the location, the main receive gain adjustment is inside the unit, rf transformer inside the unit in the receive stage of the circuit.

No output


If you antenna SWR are way out ( too high ) you may have burrned the final or driver up when you hooked it up to do the antenna adjustment. Also be sure to turn the high power switch on to adjust the antenna SWR or the SWR meter won't read correctly, if the RF power is too low. Good Luck
