get it away from the ext . speaker. They are cheap enough ,buy another one and see if it still squeals. If it does then you may have to jump the mic with resistors ,turn down your mic gain, check for talk back on rear where your pa. and external speaker hooks to inside the radio. If you see a resister connecting them then you have talk back . Mainly its a Keep the mic away from the speaker deal that makes them squeal. Try other cobra mics with the same pin out and see if it still happens . easy fix just have to be patient .
turn volume and mic gain half way up, plug in an external speaker into the PA jack, flip PA switch and key up, if it doesnt squeal your audio final is blown or it could be so simple as mic wired wrong or broken wire. try another mic.
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.
Strange. You shouldn't have a squealing problem with an RK56 noise canceling mic.
Unfortunately there is no way to change the volume of the talkback. Its too loud. The only solution is to turn the mic gain down.
The only reason you need to have talkback on is to check your audio. Make sure the echo is good and what not. After that you really don't need it on. So turn down the mic gain, then check the echo, then turn off the Talkback and turn the gain back up.
The squeal is feedback from the talkback being to loud and being heard by the mic. So the only way to solve it is to lower the volume of the talkback, (Which is not possible in this radio) lowering the mic gain(which lowers your audio level) or turning it off.
yeah your mic gain is way too high. You can either turn off talk back if you can, or turn the gain down. Depending on how loud the talk back is, your audio may suffer. If that is the case, you will not be able to run that mic. Get an RK-56 or a Skythumper mic. They are noise canceling. You will get no squeal with that mic, and it will sound awesome.
If you really want a roger beep, take it to a tech and them install one.
the talkback is too loud. there is no way to adjust the talkback volume on this radio. Talkback is really just so you can check how your audio sounds and your echo. Once it set, there is really no need to have it on.
Turning down the gain on your mic will stop the squeal.
the squeal is cause by feed back from audio from the talk back being heard from the mic.
