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...

Observations of electromagnetic (radio) signals on very low frequencies, 0 KHz - 10 KHz. Observed 10 may 2008, approx. 23.00 hour on 4,5. KHz: next to the original radio resonance of 4,5 KHz there is another resonance (spectrum on approx. 10 KHz), that comes in and fades away after 30 minutes....
