Cornell Foxhole radios are easy, fun to build, and they actually pick up signals! They don’t need a power source but work by catching radio waves with a wire antenna and converting them back to a tiny flow of electricity. With our antenna above the art room at Healdsburg High we have picked up KCBS San Francisco, and KSRO Sonoma. They can be made with just about anything you can wrap wire around. Participants will build their own radio, learn a few, simple antenna basics, and take it home to use again.
