What's the frequency, Kenneth?

 

>>4118421 (LB)

Gotcha. (my Dad used to be a radio ham a long time ago). Embedding the signal in an ELF or ULF transmission would carry it thousands of miles. It could be a very sneaky way for the Cabal to send out signals, particularly distress signals.

 

Hang on, haven't we dug into Extra Low Frequency transmissions before?

Extremely Low Frequencies (ELF) transmissions are electromagnetic waves used mainly for naval strategic communications. In general, the frequency of ELF waves range from 3 Hz to 3000 Hz.

 

Relevant to the Nov. 11th transmission? Could it be Q's 'Go' signal or the Cabal's distress call?

The United States Navy utilized extremely low frequencies (ELFs) as radio band and radio communications. The Submarine Integrated Antenna System (SIAS) was a research and development effort to communicate with submerged submarines. The Soviet/Russian Navy also utilized ELFs for submarine communications system, ZEVS. The Indian Navy has an operational ELF communication facility at the INS Kattabomman naval base to communicate with its Arihant class and Akula class submarines. A Chinese ELF facility on Hainan island, which is also the location of the Yulin Naval Base for nuclear submarines, has a military section which may be involved in submarine communications.

 

Submarine comms..?

Difficulties of ELF communication

 

One of the difficulties posed when broadcasting in the ELF frequency range is antenna size, because the length of the antenna must be at least a substantial fraction of the length of the waves. Simply put, a 3 Hz (cycle per second) signal would have a wavelength equal to the distance EM waves travel through a given medium in one third of a second. Taking account of refractive index, ELF waves propagate slightly slower than the speed of light in a vacuum. As used in military applications, the wavelength is 299,792 km (186,282 mi) per second divided by 50โ€“85 Hz, which equals around 3,500 to 6,000 km (2,200 to 3,700 mi) long. This is comparable to the Earth's diameter of around 12,742 km (7,918 mi). Because of this huge size requirement, to transmit internationally using ELF frequencies, the Earth itself forms a significant part of the antenna, and extremely long leads are necessary into the ground. Various means, such as electrical lengthening, are used to construct practical radio stations with smaller sizes.

 

What if trans-ocean data/broadband cable were being used as antennas for receiving ELF transmissions? They wouldn't interfere with the cable transmissions within and they are long enough to be able to receive them.
