Hi,

Some radios use the push to talk switch in the microphone to ground the receiver section when transmitting instead of a relay in the radio. There may be a problem with that switch, or the switching circuit in the radio itself.

If you have a PA switch make sure it is in the off position, if on it will squeal like a pig!

    Also check the mic cord for breaks or shorts.

Why is humming coming from speaker when mic is keyed?


this is strange as most times if a proper transmit key is depressed , then the radio switches from receive to transmit , the mfg know this would cause some great squeal from receiver /transmitting so close to a receiver so the part that is the receiver is muted to keep this from happening , id say there is some fault in the part that does this muting of receiver

Radio squeals part time and meter only goes up half way when keyed up


you have a Microphone problem.. change your Mic. Mine done the same thing when Mic wires shorted together inside of the handpiece. Also, when it doesn't match the Ohm impedence. you can buy a replacement Mic at www.copperelectronics.com or Radio Shack.

I have a uniden grant and i have wired a galaxy power desk mic with rogger beep when ever i key it up it squeals was wondering is there a way to fix that


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.

How can i disconnect the talk back on a connex 3300 plus? pleasa be specific on directions. thanks


in older connex 3300's you cannot disable the talk back. Its part of the audio chain. If you disable the talk back you will loose your audio. There are 2 things you can do.

Hook a relay to the speaker so that when the radio key's id disconnects the speaker. (Big pain, not worth the trouble.)

The other will not disable the talk back but it will stop any squealing.

Use a noise canceling mic. An RK-56 will work great. You will get no squealing with that mic.

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.

AKG Perception 200 Mic stopped working. I use it


The simple thing to check would be to see if your 48V phantom power switch on your mixer is turned on. Sometimes there is an individual button to turn it on and off for each channel strip. Good Luck

ICOM IC-A6 Feedback type interference


The problem is caused by the microphone preamp in the headset demodulating the AM transmission. Sordin MSA headsets also have the same problem. What you require is a headset with no electronics in it and a dynamic microphone.

CB Squeal When Transmitting


I believe the coiled coax may indeed be the problem. To check, try a temporary rerouting of the cable which eliminates the coils. Dave g.
