I want to wire my galaxy echo talklock with roger beep to my cobra 148 gtl the mic has 5 pins my cobra has 4
SOURCE: Diesel #8-32 echo power mics
cobra 4 pin is pin1= shield, pin2= mic audio (usually the shield is wrapped around the mic audio wire).pin 3= transmit or push to talk usually red or white whichever isnt wrapped with the shield, and pin4 = receive or speaker complete
5 pin cobra=1-Audio 2- Shield 3-Receive 4-Switching Wire 5-Transmit, you can jump pins 4 and two
SOURCE: how to wire a power echo mic up theres 5 wires and 4 oins
I suggest buying a 5 pin to 4 pin adapter. Ebay has them for $6. I would go chopping wires on the mic. Cobra 29 ltd is a nice radio. Have one myself.
SOURCE: superstar DM 452 echo mic wiring for a 4 pin cobra
Note: The pin numbers are marked on the end of plug.....#1.shield, #2.white, #3.red, #4.black.....that means #1.shield, #2.audio, #3.transmit, #4.recieve..........hope this helps.........
SOURCE: I need to know if it's possible to convert the
5 pin to 4 pin as follows, from the Cobra website.
1.->2 Audio
2.->1 Shield and common
3.->4 RX
4.->also goes to pin 1
5.->3 TX
