Modernized Experimental 3-TUBE Regenerative Radio

What is Modernized Experimental Radio..? Yap, it's the radio to enjoy, learn, understand and play with a tube circuit. The purpose is let our youngsters know how it works and how it's fun to make by themselves. And it's also good for seniors to re-activate their brain for the thinking. The circuit is mostly very primitive, approx. a century ago, yet the physics and electronical principals are still being working in many communication devices.

Until the end of 1960s, 3-TUBE Regen Radio was a M.H.school subject, the tubes earlier were 6C6-6ZP1(41)-12F(V1) later 6AU6-6AR5-5MK9(6X4), of housecraft & vocational class. It actually was very difficult to understand for 15-years boys there but most of them were eager beavers to catch up the US modern technorogies. They've become grewn engineers who lead Japan's core industory, then Japanese consumer electronics conquered the world as you know. This is an example education in younger age is the KEY of country developement.
