The green insulation is easy to distinguish from the bare copper, so it is easy to scrape off just the right amount when building the Simple Motor project. The Ozark Patrol circuit is a two-band shortwave receiver, using only three NPN transistors in its circuit. 1) The Jones "One-Tube" Regenerative Receiver. The simple circuits described in this article perform two functions. The main receiver board is extremely simple to construct using only one FET and an audio IC. Versions available for 80, 40, 30 and 20 Meter bands Power handling up to 100W under matched conditions Reduction of harmonics by more than 50dB Constructed on a 1. With a little practice, copying SSB and CW are a breeze. Here are plans for building a shortwave radio receiver using 3 transistors, a simple homemade coil, an Air Variable Capacitor and some common electrical parts. The MFJ-8100K World Band SWL Receiver Kit. I have not yet built this receiver, but intend to do so ASAP.
