[MRCA] GRC-106 Remote at Gilbert?

[Tom B]

According to the GRC-106 manual, the dynamic mic input goes directly 
from 1A5 to pin J on both audio connectors J18 and J19. It looks to me 
like you could easily make it work with the GRA-39 with the correct 
cable.  It looks like only one wire is moved.

I have some cables here that have two U-228 connectors and one U-77 but 
I don't know what they were made for.  It would fit the GRC-106 for this 
application but I am not sure what these were for.

I have seen a similar cable for the PSG-2.
