In this video I build the Stockton Bi-Directional Wattmeter and SWR Indicator from the G-QRP Club Telford Buildathon 2023 kit, designed by David Stockton GM4ZNX and originally published in SPRAT 61 back in 1989. The Stockton bridge is a deceptively simple circuit using just a BN43-202 binocular ferrite core and a handful of components, built here using Manhattan style construction. A great little project for any QRP station!
