Cobra highgear hg75m mic squeals


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 .

Sony vaio vgn-NR120E has no mic specially when u r on skype i can hear the caller but my voice is not heard by him...tell me the solutionWhat's your problem?


You're on a laptop and it's talking about a sound card?

If you can hear audio or the voice from the caller then you don't need a sound card.

Yes you can purchase an external mic and it just plugs into the mic port on your system. I think that might be why the caller can't hear you. All computers do not come with a built in microphone. And if you are skyping and using a web cam, all web cams don't have a built in microphone.

An external microphone will not cut out the background noises, no matter what settings we change...the built in mic is disabled, but the noise in the background is very loud unless we are talking, and evn...


Most microphones (especially those made for use in a computer) do not remove any background noise. This is usually done via software, but it might not be available on every app out there.

If you can't talk properly using your current mic, your best option might be getting a headset. Headsets have a less sensitive microphone, which will tend to pick up only your voice. If you have a bluetooth headset, you can use it on your computer by adding a bluetooth dongle.

How do i switch off the internal mike?


When you connect the external mic to the laptop,automatically the internal mic will be disabled. If you are talking about just disabling, you can mute that through sound properties on the right side bottom.

Push to talk problem


Hi,

If indeed radio #1 has a mic problem, this may be confirmed by trying an external speaker/microphone plugged into the accessory jack. If still a no, then its not the mic but possibly the modulator circuitry. If there is transmit audio with the external mic and hence internal mic is defective, the unit would have to be pried open and the defective component replaced. The internal mic is normally an electrofet 2-3 terminal soldered to a shielded wire and physically attached to the front plate.

Alternately, another possibility is that radio #2 has its Interference Eliminator Code enabled/activated. This is indicated by the presence of small sized digits on the top right of display. If this is the case and no similar digits are displayed in radio #1, then radio #2 will not allow any received transmission to be heard. Along the same line of reasoning, if the code is activated on both radios signified by the presence of the 2 small digits, and radio #1 has a problem with its CTCSS (code) generator, then it would also prevent reception of radio #2. A way to verify this is by deactivating/disabling the Interference Eliminator Codes on both radios.

On certain occasion, it is also possible that radio #2 has a defective speaker. You should be able to verify this by plugging in an external speaker to the accessory jack of radio #2.

Hope this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
