How to change the Kenwood Mic jack

This is how we change the Kenwood microphone jack when needed

Sometimes it happens that the jack is broken or not working anymore. it is easy to change it like installing an RJ45 for a network cable but we have to be careful of some wires..

The kenwood microphone cable is consisted of 6 clear wires with different colors ( Red, Green, Black, Blue, Yellow, Grey and a mysterious wire covered with shield ! )
This mysterious one is like 2x wires in one, the outer shield we cut, and then you can find a white wire covered with silver shield, those two are considered as two additional wires so the total is 8:
Red, Green, Black, Blue, Yellow, Grey, White and Silver shield..

The picture below explains how to change the RJ45 jack of a Kenwood Microphone like KMC-30, 32 and similar models.

The correct order of wires from left to right is:

Yellow, Grey, White, Silver, Blue, Black, Red and Green

Motorola GM-360 pinout

I found this somewhere

Motorola GM pinout

1)  speaker -

2)  external mic

3)  digital in 1 (ext.PTT use external mic/data PTT use flat Tx audio)

4)  digital out 2 (external alarm)

5)  flat Tx audio, sensitivity 150mV rms to 60% deviation

6)  digital in 3

7)  ground

8) digital in/out 4

9)  digital in 5 with wakeup (emergency)

10) digital in 6 with wakeup (ignition)

11) flat/filtered Rx audio

12) digital in/out 7

13) switched battery voltage (max.1A,dropout voltage max. 1V)

14) digital in/out8

15) RSSI (radio signal strength indicator)

16) speaker +

17) BUS + (used for CFPS and Flash)

18) BOOT control

19) reserved

20) reserved

and position of pins goes: upper pins from left to right: 20,2 4,6,8,10,12,14,16,18

                                  bottom  pins from left to right : 19,1,3,5,7,9,11,13,15,17,

Motorola GP360 antenna models

Having to work with 140Mhz, I had to lookup proper antennas for this frequency, as our standard GP360 antennas are usually 155-174MHz.
Here is the complete table of available stubby antennas.


Part Number - Frequency - Length - Colour

PMAD4012 (136 - 155 MHz) 9cm Antenna Red
PMAD4013 (155 - 174 MHz) 9cm Antenna Black
PMAD4014 (136 - 155 MHz) 14cm Antenna Red
PMAD4015 (155 - 174 MHz) 14cm Antenna Black
PMAD4023 (150 - 161 MHz) 14cm Antenna Brown
PMAD4025 (150 - 161 MHz) 9cm Antenna Brown
PMAE4002 (403 - 433 MHz) 9cm Antenna Green
PMAE4003 (438 - 470 MHz) 9cm Helical Antenna Grey/Silver
NAE6483 (403 - 470 MHz) Whip Antenna Black



Note.
The use of the 9cm antenna in the VHF application will cause reduction in the operational range.

Colour Code
                     
The colour code can be either in the middle or around the antenna connector screw.
