Welcome to the website of the Joplin Amateur Radio Club. We are located in Joplin, MO and operate under callsign WØIN.  We are a 501-c4 public service organization and an ARRL affiliated club.

The officers for 2017 are:

  • President: Ray Brown, KBØSTN
  • Vice President: Jim Scott, WBØIYC
  • Secretary: Jason Arends, KØJAA
  • Treasurer: Gerald Jones, ADØPF

If you would like to find out more about the club, look around the site (use the menus at the top) and drop in to any of our meetings or nets.  If you are not yet a licensed ham, let use know if you are interested in taking a class to get your license. VE Testing is also available in the area.  All amateur radio enthusiasts are welcome at our events, member and non-member alike.

The club also sells antenna launcher kits which are put together by club members right here in Joplin, MO, USA and can be shipped anywhere.  These are great for putting up antennas either in your yard, or at a Field Day site!

Feel free to register on this site – if you are a member, this will give you access to the member’s area, but non-members can also comment on posts.
