Motorola accessory socket adapter

In order to be able to easily connect the accessory socket from the back of Motorola transceiver (types GMxxx ,…), I realize a small PCB which allows:

  • Connect 12V to allow automatic re-ignition after loss of power
  • To adjust the audio level of the reception
  • To connect an interface assembly such as MMDVM or SVXCard via a 6-pin mini-DIN cable
  • To allow the transmission of the RSSI signal level voltage to the mini-DIN

The diagram is as follows.

The adapter kit for Motorola and its PCB may be available through grouped purchases on ShopChip


If you would be interested to participate in a possible future new grouped order (MMDVM board, SvxLink Card), leave your email below to be reported!

    1. Like you can see it on schematic, just a MiniDin 6 pol, a 2 rows flat connector (2×8), a 10K potentiometer and some pin header for testing…

      Nothing very complicated to find. Some kits are still available on
