Update: regenerative receivers

A few more pics of my AM and short wave regenerative receivers.

Left to right:G3XBM, 40 meters, JFET; Stan Gibilisco, AM broadcast band; Selenium, et. al, short wave; Normal Leal (Antique Radio Forum), space charge tube radio 12 VDC, AM broadcast band; and VK3EYE, 40 meters short wave using ceramic resonators instead of a coil in the tank circuit.

Bottom photo: Selenium again (refer to the Radio Boards Forums under solid state designs) using an LM386 as an envelop detector, AM broadcast.

I found these designs on You Tube, websites, Antique Radio Forum, and The Radio Board Forum.
