October 8 2020 — The origins of the microwave oven can be traced to World War II. Scientists in Britain had developed the magnetron, a tube that produces microwaves, as part of a radar system to spot Nazi warplanes. Follow us on Twitter: @INTEL_TODAY

UPDATE (October 8 2021) — A recently declassified 2018 report to the State Department concluded that Havana Syndrome cases were caused by crickets as opposed to microwave weapons.
The report argued that a possible explanation for the reported symptoms is a psychogenic illness.
This report is utter nonsense and it has been dismissed by the State Department because of its obvious shortcomings.
The White House, the Pentagon, the CIA, and even the FBI have reiterated their belief that the Havana Syndrome is very real and affecting intelligence officers and diplomats.
There is an interesting rumor as to why JASON would have produced such an fake scientific report.
According to that RUMINT, some folks in the White House feared that the Havana Syndrome attacks could be linked to Moscow, and this was not welcome news in the context of Russiagate.
I do not know if there is any truth to that story, and I do not care much.
Let me repeat. This report is utter nonsense. Professor James Lin — a University of Illinois biomedical engineer — makes it very clear in just one sentence.
“A typical sound recorder is not be able to record the ‘microwave sound’. Period.”
It is rather obvious that the only person interviewed by the Jason researchers had erroneously reported symptoms commonly associated with anomalous health incidents.
This claim should have been dismissed immediately.
And yet, the JASON report goes on and on to explain that microwaves cannot be the source of the recorded sound!?! Why on earth? Well, when you earn US$ 5,000 per day to work on a JASON report, a simple answer is not always your best option…

As a rule, there is no point to read and study nonsensical reports. In this case, there is however a clue revealing the background behind the scene.
The chapter of the JASON report dealing with microwaves is almost entirely redacted, except for the first 2 pages.
Despite heavy redaction, we can learn a few things from these pages.
1 — Notice the sentence:
“The frequencies of interest for RF weapons are [redacted.]”
Well, obviously, RF weapons are not science fiction…
2 — The frequency range is redacted, but the report goes on to mention that, in this range, the limit is set to 1% of the sunlight power density (about 100 mW/m2). Obviously, the possible frequency range goes from 1 GHz to 100 GHz.
The reader familiar with this blog will remember that I have long argued that the frequency range used by the US Intel Community for microwave spying is around 1 to 2 GHz. [My conclusion is based on the analysis of a document revealed by SNOWDEN that has been ignored by all MSM so far.]

3 — The JASON report claims that the limit is conservative because it is set at 1% of the sunlight. This is utter nonsense. The sunlight has an effect on the skin and can badly affect the cornea, but it cannot penetrate the brain because of its very short wavelength. On the other hand, microwaves can penetrate and affect the brain as the Frey effect demonstrates.
4 — It is extremely suspicious that JASON uses this FCC plot to claim that microwaves are safe under these limits. In truth, this plot does not prove anything. It assumes that the only effect of microwaves are tissues heating which are also assumed to be harmless to some extent.

And now let me tell you a story. This FCC plot, or a very similar plot, is the basis of the law that limits the maximum power of GSM antennas all over the world.
Considering the importance of this plot, one would assume that the origin of this plot is well documented. One would be wrong.
Over the years, I have asked dozens of top experts if they knew how these limits have been computed. Not one was ever able to give me a correct answer!
To the best of my knowledge, I am the only person who has spent the time to research the origin of this plot. When I tell you that story, you will be horrified…

The technology was passed to the United States, and Raytheon was among the companies putting it to use for the military.
In early 1945, the Raytheon Company was looking for something to sell to civilians after World War II was over. The company’s head, Laurence Marshall, convened a team of technicians to come up with an answer.
One of these technicians, Percy Spencer, suggested that Raytheon should build on its radar expertise by making an oven. He had walked by a microwave tube one day and noticed that a candy bar in his pocket had melted. Intrigued, he placed some popcorn kernels near the tube and watched them pop all over his lab. The next morning, he exploded an egg for a colleague.
Earlier this year, I posted a story — On This Day — US Surgeon General Report Links Tobacco and Cancer (January 11 1964) [5G & Cancer] — that prompted the following comment:
“Microwaves have not been proven to cause cancer, in fact the Varian associates medical division actually uses microwaves to cure cancer.
Also there is no evidence the Havana syndrome has anything to do with microwaves, an urban vernacular to attribute just about every malady and malfunction to those mysterious microwaves. Not really mysterious, every kitchen has one.
The magnetron that powers these common devices is the same as the ones that spotted the Japanese aircraft flying towards Pearl Harbor at the start of WW2, been around a very long time.”
Edgar Gillham, team leader in advanced development, ALQ-131 electronic countermeasures for USA and allied aircraft.
First thing first… In 2018, the U.S. National Toxicology Program (NTP) concluded that microwave radiation causes cancer.
This year, the NTP will begin a systematic search for mechanisms to explain how and why the tumors developed. [NTP Turns to Mechanisms — DNA Breaks, Oxidative Stress and Gene Expression Are on the Agenda]
Second. The cavity magnetron was not yet used in RADAR at the time of Pearl harbor.
The invention of the cavity magnetron made possible the production of electromagnetic waves of a small enough wavelength (microwaves). The magnetron was originally a crucial component in the development of short wavelength radar during World War II.
In 1937–1940, a multi-cavity magnetron was built by the British physicist Sir John Turton Randall, FRSE, together with a team of British coworkers, for the British and American military radar installations in World War II. A more high-powered microwave generator that worked at shorter wavelengths was needed, and in 1940, at the University of Birmingham in England, Randall and Harry Boot produced a working prototype. They invented a valve that could produce pulses of microwave radio energy on a wavelength of 10 cm, an unprecedented discovery.
Sir Henry Tizard traveled to the U.S. in late September 1940 to offer the magnetron in exchange for their financial and industrial help. An early 6 kW version, built in England by the General Electric Company Research Laboratories, Wembley, London, was given to the U.S. government in September 1940. The magnetron was later described by American historian James Phinney Baxter III as the “most valuable cargo ever brought to our shores”. Contracts were awarded to Raytheon and other companies for the mass production of the magnetron. [Wikipedia]
In May 1939, a contract was awarded to RCA for production. Designated CXAM, deliveries started in May 1940. The acronym RADAR was coined from “Radio Detection And Ranging”.
One of the first CXAM systems was placed aboard the USS California, a battleship that was sunk in the Japanese attack on Pearl Harbor on December 7, 1941.
The CXAM radar system was the first production radar system deployed on United States Navy ships, operating in the mid-high VHF frequency band of 200 MHz, about a tenth of the frequency used by a microwave oven.
Of course, people were well aware of the advantages of microwaves for RADAR but without the cavity magnetron, this frequency band was simply not a option.
