The Delaware Valley Radio Association will host an amateur radio direction finding workshop at the club station on Saturday April 6, 2019 from 10:00am to 12:00pm.

This event is free and is open to both members and non-members. You do not need to be a licensed amateur radio operator to participate.

At the workshop, club members will demonstrate various amateur radio direction finding equipment and techniques that can be used at future ‘foxhunts’ the club will host in Mercer County later in April and May. It is also an opportunity to learn about different aspects of the amateur radio hobby. Optionally, assistance is available to help attendees construct their own tape measure yagi antenna. A parts and materials list is available at the end of this article.
