I have no mike audio. Where's the mic gain pot inside the radio?

lets see,do you have another cover? If you do then cut that sucker off nd put the other one on.

Astaic 36L. You never want to run a power Mike with a good radio with Mic Gain. Road King is great to. It is very hard to find the honey spot with a power Mike when you have Mike gain on radio.I think it is pretty hard to beat the 36L. I use one one my Connex 4600 Turbo and Galaxy 95T2, They both performe great. Connex is a little better a DX ing though

I MIGHT BE WRONG BUT I THINK THE $() ALREADY HAS AN ADJUSTMENT ON THE FRONT OF THE RADIO ITS CALLED THE MIC GAIN THIS CONTROL SHOULD LET YOU ADJUST THE LEVEL WITHOUT GOING INSIDE THE RADIO

take some electrical spray cleaner and lightly spray the inside of the radio where the mic plugs in. could also be a keying diode.

Check that your mic gain or dynamike knob is turn clockwise if it is full counter clockwise you will have no modulation with your tx power.
I would like to help but one sentence describing your problem can lead to a vague solution.
Be aware that not all 4 pin mikes are wired the same.

change "MIC" to a factory,or turn back Mic gain. Mic can short out or may have too much gain(power mics). Use standard dead Mic that was designed for radio. If that does not help,it may be inside radio, wires on MIC connectors need soldered again(make sure they don't touch th eothers.

sounds like a faulty "MIC" or bad knob inside radio. Your radio may have too much gain. Try using a ordinary straight "MIC" . Some radios are tuned to operate with a straight mic. If you use a "Power Mic" it may be too much gain and cause a squeal. Impedance of the mic must be matched. If its a 500 ohm use only 500 ohm. If its an 1000 ohm use only 1000 ohm "Mics". A straight factory Cobra mic(Coffin mic) has gave me the best performance I have ever used on a Cb radio. I can talk 50 miles on straight mics.

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.
  

Try a hand mic with the set, there may be a short within the radio.If not your problem is with the audio amp in the radio itself.Repair should be about $15.00.

Check for proper shielding,ground, turn mic gain down, move mike farther away from radio, turn off other accessories nearby-ie.-am/fm radio
