[MRCA] R-4 connector

[Ulrich N Fierz]

Good morning AlI have also one of these radios but including the power supply box (AC and battery automatic switchover). The two are interconnected with a screened cable using the connectors you show. Unfortunately my radio is at our summer house some 200+ kms from here so I cannot verify my theory.
IMHO these are a copy of the DIN 41622/41618 connectors originally developed by I believe SIEMENS. I suggest you have a lokk at a data sheet for the series to verify the dimensions. You probably will not find the correct type, but a longer three row female (Federleiste) can be shortened to fit. Have a look at the German Ebay site (they are not currently manufactured) and look at 123730561276 to see what I'm talking about. I might even have some three row females in my basement somewhere. 

Good fun with the radio, it performs well.
