 Designed by David Cripe, NMØS, the 4S-Dummy Load is a simple kit that employs the use of large SMT parts and some LEDs to provide a dummy load device for up to 10W output.
The power-indicator LEDs indicate output power in a cascade method.
This kit is useful for showing if your transmitter is making power - or not !
It should be a commonly-used test device on the QRP builder's bench.

 The extra large 2512-sized SMT parts used in this kit are an easy and great learning experience.
