The counterpoise for the VLF receiver is a small ground stake, located as far away from any underground cables as possible. To avoid overloading the FM transmitter with the strong Navy transmitters, an 8-pole 15 kHz lowpass was added between the VLF receiver and the UHF transmitter: See also: Radio Direction Finding on VLF,
OPERATOR MANUAL 3 20 ft. RG8/U output cable(VLF-4022), 12 ft. shielded X-Ray output cable(VLF-6022) Hook type output connector Alligator clip type output connector WARNING DO NOT OPERATE THE VLF HIPOT SET IF THE HIGH VOLTAGE TANK IS 5 OR MORE FROM LEVEL. IF THE UNIT IS OPERATED OUT OF LEVEL, OVERHEATING AND INTERNAL ARCING MAY OCCUR. How to build a VLF Receiver The basic principle of the SID receiver is to measure the amplitude of a VLF station and to convert it to digital data. The signal from the antenna (usually a loop antenna) is filtered out to limit the signals to the frequencies of interest in the VLF and lower-LF frequency range. Amateur Radio Astronomy Projects—A Whistler Radio schematic diagram of the Gyrator II VLF receiver. When our Graphics Department created the schematic, a 0.001 µF capacitor, C4, was omitted between sections U1A and U1B of the op amp. When I reviewed the VLF receivers.
