This year’s Dayton Hamvention®, host of the 2019 ARRL National Convention, will be the first year a mobile event app will help attendees navigate the extensive Hamvention program, activities, and exhibits from their personal smartphone or tablet. The app is a collaborative effort between ARRL and Dayton Hamvention.
Besides exhibits and forums, the app will include schedules and details for affiliated events, such as dinners and other special gatherings, and a feature to allow attendees to following the hourly prize drawings from wherever they are. Attendees are also encouraged to tap on the “MyProfile” icon to optionally include their name and call sign, email address, and any other information they’d like to share with other attendees.
The icon labeled “Scan Badge” will allow users to scan a QR Code displayed on a second device using the icon labeled “MyBadge” – instantly connecting your shared contact information with another ham. The 2019 Dayton Hamvention event app is available for both Apple and Android smart devices. Visit your app store to download it, or find links at www.arrl.org/expo. 2019 Hamvention is May 17-19 in Xenia, Ohio.
