Has anyone here made a simple repeater out of 2 Motorola GM300 radios?

Looking for help with a 16 pin bidirectional cable and software setting in the radios.

OP - the cable you are showing is for making a cross-band bidirectional repeater out of a set of UHF & VHF radios. Great if you want to link 2 groups of radios, one using UHF and another using VHF. Not so great for basic UHF GMRS repeater operation.

The uni-directional repeater cable is the one you want.

I'd tell you to spend a few dollars more though, and get one from a guy on Ebay named Kurt Meltzer - MRE Direct.  He will use the correct tabs which force (OK, actually allow) proper tab orientation, and he'll include instructions with the cable kit(s).  You can reach him at: mre1032 <at> yahoo.com or look him up on Ebay.
