[Home made/own GMRS Repeater]

Hello!

I am new to the forum. My call sign is WRSL266 and I live in the city of Miami, FL. I really like the idea of being able to have direct communication with friends, groups and my family through a GMRS repeater.

How can I make my own functional, low-priced repeater to share with my community?

I appreciate all the information you can give me.
