Codar CR-66 receiver, classic British set, a slice of history.

Movie about the radio's from the Hallicrafters co.

Schematic of the 4 tube radio, experimentally built in a way of the radio-pioneers (1910-1945). The radio acts as a cascade type receiver when the antenna coil has a high self-inductance, with lower self-inductances of the antenna coil you can put in a mixing process with the oscillator. Perhaps...

US War department movie about the SCR-694

Experimental receiver for VLF. I received electromagnetic (radio) signals between 14 and 22 KHz with a capacitor of 4,7 NF over the showed coil. The schematic is identical to that of the storm detector IV (with the 6088 Tube), the coil is differently constructed. There is one more transistor...

After 2 hours of bush whacking our way up a steep slope through scrub oak and dangerous loose rock my goats and I reached the south summit. Exhausted we made our way to the north summit where I had stashed a battery but spent the next 45 minutes looking for it! Once found we put up a sloper for...
