    Thank you, yes they are the 6MM. Found that out by purchasing 4MM, 5MM and 6MM. The 6MM fit.

    Thanks again

Hello ptcruiser 1, I don't have one of those radios right here in front of me, but if I remember correctly the knobs are 6mm. I'm trying to remember for sure but I know their not 5mm, that's the size of most Cobra's. It's been over a year since I've had my store open, so I'm working from memory. That's the best I've got,,, Mechanic

I have a refurbished unit I purchased a couple of months ago and it works great but I put it back in my truck and noticed that when I tightened the knobs and will go off than if I back it off it comes on?...

yes common problem with the larger export chassis. the voltage regulator comes un-soldered from the board. re-solder and it will fix the problem. or have a cb shop do it... THEY SHOULDN'T CHARGER MORE THAN $5 for that..!!!!!

also do not use any other knobs/screws longer than what came factory with it. they will hit stuff inside and can short out components. They should be less than 1/4" long..

My radio recieves ok but only whistles when i key the mike is this a major fix?

Do you have talkback installed? It my be too loud and causing feed back. Back the mic gain down if so.

Could also be improper mic wiring. If you use a mic that is wired for a different radio, it could just cause a hum, buzz or squeal.

Another thing that can cause a hum, buzz or squeal is a faulty volume and or squelch knob depending on the radio.

  • Turn down or disable talk back.
  • If you cannot turn off or disable talk back, lower mic gain.
  • Try a different mic that you know is wired for cobra.
  • Play with volume and squelch knobs while TX and see if it stops at all. If it does replace knob.

Big Knob settings from left to right...
First knobset...inner turn "volume" fully clockwise
... outer "squelch" fully counterclockwise
Second knobset...both inner and outer knobs fully clockwise
Third knob...chose which mode you want to use...Am or Fm (If your radio has been modified to TX/RX CB frequencies, chose AM)
Fourth knob...chose your band (If your radio has been modified to TX/RX CB frequencies, chose band D/A)
The only other knob that is important is the high/low power switch. It selects the band from the pair chosen by the band knob. I don't know if band D corresponds to high or low, so try both settings until one works.

If you can't TX or RX with these settings either there is no one talking at that time or your radio, antenna, or cable might be defective. You should get a copy of the owners manual to fully learn how to chose bands and adjust the settings. I've given you a starting point that should work but may not be optimum for all conditions.

I have a Ranger 6900F Jumbo

left to right,Volume,on/off(center) Squelch (outside)2nd knob is mic gain (center) this controls how much adio output you produce.. and rf gain,(outside) This adjust how sensitive the radio recieves.3rd knob is pa/fm/am This sets the radio up for using a public address horn if hooked up, or to transmit and recieve on am (most common) or fm.
The next knob controls what bands o channels you operate on .6 bands of channels with 40 channels each.The next knob controls the amount of echo and reverb you use when you talk.The center controls the echo and the outside controls the speed,or reverb effect.The next knob controls the talk back(so you hear what you sound like on the center control, and the outside controls how much power you put out.The next knob, the biggest one is your channel selector.The push buttons are top l to r are:1 is the dimmer switch for your lights,the middel top is noise blanker and automatic noise limiter. This blanks out a lot of static and outside electrical noise.the last top switch is a roger beep switch to turn it on and off. When it is on you will produce a quick beep when you unkey the mike. This was originally used to let the other people on the bands know you stopped talking.The bottom left shuts off the frequency counter(the numbered display ie27.185,the middle sets the meter to be used as an swr meter or a regular s/rf meter.the last on the bottom will boost the frequencet up100 kilohertz.if you go to the following url you can get more info:

Cobra 25 no receive & no modulation

Hello 49er, When you say "no receive", do you mean no sound, or no signal on the meter at all??I'm just grabbing at straws here so bear with me as there can be different problems doing the same thing.If this radio has been tightened up in a bracket, sometimes that will pull the solder legs loose on the audio chip. That could take away the mod. and RX volume. Is the Microphone ok? If the radio has been in storage, the switches and knobs could have dust and dirt in them. How much troubleshooting are you comfortable with?? If your not, then you might need to take it to a good CB Radio Repair shop to have it serviced. That's what I used to do for over 10 years,,, Let me know how your coming along,,, Mechanic
