US Navy ELF Transmitter 76Hz
Clam Lake, Wisconsin, USA
Frequency: 76 Hz at 3 MW (3,000 kW)
The U.S. Navy operates two extremely low frequency radio transmitters to communicate with its deep diving submarines. The sites at Clam Lake, Wisconsin and Republic, Michigan are operated by the Naval Computer and Telecommunications Area Master Station – Atlantic. The Clam Lake site, located in the Chequamegon National Forest in Northern Wisconsin, is the site where testing began for ELF communications more than 30 years ago. The site has more than 28 miles of over-head signal transmission line thatform part of the “electrical” antenna to radiate the ELF signal from the two-acre transmitting facility.
The Clam Lake ELF radio station broadcasts messages to the fleet as required by the Navy Submarine Broadcast Control Authority in Norfolk, Virginia or Pearl Harbor, Hawaii. For the U.S. submarine fleet to perform its mission, it must remain silent and be undetectable. The Navy’s ELF communications system is the only operational communications system that can penetrate seawater to great depths and is virtually jam proof from both natural and man-made interference.

The Grimeton VLF transmitter is a VLF transmission facility at Grimeton close to Varberg, Sweden. It has the only workable machine transmitter in the world and is classified as World Heritage Site.
The transmitter was built in 1922 to 1924; to operate at 17.2 kHz, although it is designed for frequencies around 40 kHz. The radiating element is a wire aerial hung on six 127-metre high freestanding steel pylons, that are grounded.
The Grimeton VLF transmitter location is also used for shortwave transmissions, FM and TV broadcasting. For this purpose, a 260 metre high guyed steel framework mast was built in 1966 next to the building containing the 40 kHz transmitter.

GBZ is the call sign of a British VLF transmitter on 19.6 kHz from Anthorn, Cumbria (formerly from Criggion, Powys), which is involved with transmitting encrypted signals to submarines. Although the signals of GBZ cannot be decrypted by common means, its reception - if its signal is shown in the form of spectrograms - is very interesting, because the signals of GBZ show figures looking like fishes, garlands and ornaments on the spectrograms.[1] At certain times these signals are also transmitted as strong pulses, so-called superpulses, which can oversteer the amplifier of a PC soundcard at distances of a hundred kilometres away from transmission site.

The "Vileyka" VLF transmitter is the site of the 43rd Communications Center of the Russian Navy (Russian: 43-й узел связи ВМФ России), situated west of the town of Vileyka in Belarus (54°27′49″N 26°46′44″ECoordinates: 54°27′49″N 26°46′44″E). The "Vileyka" VLF transmitter is an important facility for transmitting orders to submarines in the very low frequency range. Beside this, it is used for transmitting the time signal RJH69 at certain times.
As the former Goliath transmitter of the German Navy in World War II, the antenna system of the "Vileyka" VLF transmitter consists of 3 antenna systems with a central mast insulated against ground from which antenna wires run to 6 grounded ring masts, where they are fixed by insulators. As at former Goliath transmitter, 3 ring masts carry two antenna systems, so there are only 15 ring masts on the site. A further common ground to former Goliath transmitter is, that the ring masts of the Goliath transmitter are masts of lattice steel with triangular cross section, while the central masts are steel tube masts.
The ring masts of the "Vileyka" VLF transmitter are 270 metres and the central masts of VLF transmitter are 305 metres tall. Their height surpasses therefore the height of the masts of former Goliath transmitter nearly exactly of 100 metres.
