I show you how you can make a cable for my Retevis RT97s or midland mxr10 interface board so it can be hooked up to ANY mobile GMRS two-way radio so date & time & weather & repeater ID announcements ONLY can be played!
NO ZELLO!!!
NOTE: when using the front mic jack the interface board is NOT told when the repeater is in use, so when date and time, etc. is played it will key up over someone if someone is using the repeater at that same time date & time, etc. is played!!!
