Cant transmit i bought a cobra 25 had to buy a mic when i key the mic is when i recieve but cannot transmit could it be the microphone please help new to hobby


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!

Mic hum Hello, I recently obtained a Superstar 140 radio without a mic. I connected a mic from a uniden pc76xl and every time I key up there is a loud humming noise coming from the mic. It does not come from the radios speaker but through the mic itself. Would it be that the wirin gis different on these radios. If so where can I get the diagram for the wiring. The mic is a from a Galaxy radio. Any help would be appreciated. Thank You. Nef...


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- Audio2-Ground (Shield)3-Receive4-TransmitDepending 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.
