Assembly & Ops
... designed in 2007 by the great Joe Everhart, N2CX
The Rainbow Tuner doesn’t really tune rainbows, but it does use a rainbow of sorts to show the SWR of the antenna system connected to it. The "Rainbow" embodies the Spartan design philosophy exemplified by the 40-9er, the Pixie, the Fireball 40, the MRX-40, and many other simple QRP radios that have been available over the years. It combines a very special antenna tuner with a simple-to-use and accurate SWR meter. Intended to fit in popular mint tins, it can be built for about $30. The heart of the Rainbow Tuner is a colorful, user-friendly SWR indicator that can be used by itself or in other homebrew projects.
