ARRL once again will be out in force at Hamvention® — May 18 – 20 at the Greene County Fairgrounds and Expo Center in Xenia, Ohio. The largest annual Amateur Radio gathering in the US this year has been sanctioned as the 2018 ARRL Great Lakes Division Convention. This is only Hamvention’s second year at its new location in Xenia after decades at the now-shuttered Hara Arena.
