The QSL card for K3K, commemorating the Kulpsville SWL Fest 2004, features a minimalist design highlighted by bold lettering that prominently displays "K3K" and the event name above a vintage-style depiction of the location. The card notes the venue, "The Inn at Towamencin," along with its address in Kulpsville, Pennsylvania, USA. The reverse side is structured for confirming radio communication details, including a space for the date, time (UTC), frequency (MHz), signal report (RST), mode of communication, and additional remarks, providing a practical tool for amateur radio operators to document their QSO experiences. The card also invites users to affix a postage stamp, underscoring its function as a traditional communication tool in the ham radio community.
