Sample of 20 Meter Activity for PSK31 Introduction Video

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...

The X-Band microwave motion detector was moved to 10.25GHz. We explore the output of the HP x421A detector diode attached to the HP x532A X-Band wavemeter, and verify the frequency of operation.
