Lesson learned for future Field Day

A highlight of Winter Field Day weekend was when Elecraft co-founder Wayne Burdick (N6KR) and his son Griffin dropped by our Winter Field Day site at Henry Coe State Park.  

Wayne noticed we were using a pair of KX3s, and he provided some info on a little-known Elecraft feature for improved co-station isolation in multi-multi environments like Field Day:  Using the transceiver’s menu to set “RX ISO” to “on” will suppress any radiation from the local oscillator that might otherwise leak to the antenna. This helps minimize oscillator birdies that could interfer with reception at the site’s other stations.   

Definitely worth remembering this feature at Field Day in June!
