No sound transmitting from Soundstation EX wireless mic # 2201-00699-002

You've obviously checked battery strength, battery connection and volume settings for the dead mic...does the green transmit (RF) LED light when you turn the mic on? Does the red audio (AF) LED light when you talk into the mic? Best solution....buy a better quality wireless system ($85 wireless?!? ...no thanks).

You mean NO Audio Transmit?
If there is No Audio at PTT Bad MIc Cord.
Change the Mic cord.

Hi,my name is John. Welcome to FixYa. Your power mic. needs to be wired the the radio. Thanks for choosing FixYa....John

Try to increace volume over the phone settings itself. If its already max, then just replace the mic and that's it.

If you need more detail, just let me know.

Best of luck

Hello Darren, Yes it sounds like the mic is wired bass ackwards,,! A cobra 25 mic wiring is
PIN #1- Shield or ground wire
PIN#2- Audio or Transmit modulation
PIN #3- Transmit or Dead Key
PIN #4- Receive Audio.
When your keying the mic, the RX wires are being connected to make the RX work,,,
*** Let me know how you get along with it. Either buy a new mic wired for your radio or you or someone comfortable with soldering needs to resolder the correct wires back on the mic plug,,,Like I said, let me know and have a great day,, Mechanic is back quiet!

Please I have the same issue, the receiver cannot hear whjat we are saying our voice is very faint to the receiver as if we are calling from a very far distant location from the phone.

Yes, the wiring is different. Reverse the wires on pins 1 & 2, then reverse the wires on pins 3 & 4.

The wiring for you radio's mike is:

1- Audio
2-Ground (Shield)
3-Receive
4-Transmit

Depending on the vintage of your mike, the colors Uniden uses for these functions are white or yellow for audio, red is transmit & black is receive.

please check if your wiring was correct or you don't have a bad wiring in there...

sound changes to external mic. when any ex. mic. is inserted the internal mic. comes out of order then you don't and can't have two sounds same time that mean you only get the ex. mic sound regards please don't forget to rate thx
