The American Radio Relay League (ARRL) is the national association for amateur radio and you can join the nearly 160,000 members nationwide and nearly 2,000 members in Oklahoma. The benefits of membership far exceed the cost and range from QST, the monthly magazine to help with renewing your license and they are detailed on the ARRL Member Benefits page.
You can join or renew your membership at ARRL sponsored hamfests, over the phone, via snail mail, through your local club, or online at https://www.arrl.org/join.
