	Simple AM BC Radio using just an LM-386 audio IC it's surprisingly good!  The LM-386 has long been a favorite audio amplifier for getting the audio from a direct conversion or other type of receiver up to the 1 watt level to drive a speaker.   But some clever fellows came up with a way to turn this high-gain linear IC into a regenerative receiver all by itself, and I just had to try it. The result surprised me.  Unlike most regens which are a c...  READ MORE	ranickels 04/26/2019	RAN Technology Product demos

	Crystals Go To War A documentary about the technology that won WWII Clear communications were critical to the success of the Allies in World War II. The stability of the Allied transmitters and receivers depended on the performance of tiny quartz crystals. During WWII, the heavy reliance on these crystals spurred on tremendous advances in the manufacturing of dependable crystals. Before the wartime need, the performance of radio crystals was largely inconsistent b...  READ MORE	ranickels 04/12/2019	Ham Radio Information
