A klystron is a specialized linear-beam vacuum tube that amplifies low frequencies for communications A. Yes B. No Answer B… A klystron is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power klystrons are used as output tubes in UHF television transmitters, satellite communication, radar transmitters, and to generate the drive power for modern particle accelerators.

Fred M Link of the Fred M. Link Co. 1931 – 1950 is known as the pioneer of VHF FM police communications Yes No Answer is Yes… Link received the IEEE Centennial Medal in 1984. An IEEE milestone plaque at the entrance of the Connecticut Department of Public Safety headquarters in Middletown, Conn., commemorates the installation of the first FM police radio communications system, which was built by Link Radio. It was the success of this system that led to adopting FM radio for communications by the Mechanized Cavalry (tanks) based in Fort Monmouth, N.J., used in World War II.

WN1M Answer is A… WNP stands for “Wireless North Pole”… The other call sign is Michael Marinaro’s, WN1M who wrote the QST article in 2014 on the expeditions communications, The article is below…..
SpaceX’s Star Link is a network of satellites to bring down the cost and improve broadband world wide eventually. The satellites use a fuel called Krypton: Is Krypton (A) a natural gas or is it (B) man made A. Natural B. Man Made Answer A…. Krypton is known as a noble gas which is chemically inert. Krypton, like the other noble gases, is used in lighting and photography. Krypton light has many spectral lines, and krypton plasma is useful in bright, high-powered gas lasers. Krypton was discovered in 1898 in Great Britain by William Ramsay, a Scottish chemist, and Morris Travers, an English chemist, in residue left from evaporating nearly all components of liquid air.

Super Dual Auroral Radar Network (aka SuperDARN) which is a network of 32 radars operating on frequencies between 8 and 20 MHz and looking into the polar regions of the Earth is operated by NATO, The US Government or a University
B. US Government C. University
Answer C… SuperDARN is operated by the Johns Hopkins University Applied Physics Laboratory. When a rocket is shot off such as the recent SpaceX’s, you can track them in real time
In 2015 Roastbeef Productions produced a war/documentary film called The Russian Woodpecker A. True B. False Answer A… The film written, produced and directed by Chad Gracia began as a 5 minute film about the Duga Radar Antenna (aka The Russian woodpecker) for his friends and family and this led him to following Fedor Alexandrovich’s investigation into the Chernobyl disaster and how the 2 may be connected Links
A mystery signal heard on 4 frequencies in 2004, 3.7 mhz, 4.3, 6.5 mhz and 10.5 mhz ending on December 23rd and then beginning again on the 14th of January 2005 adding a new group of frequencies which just happened to be the international time frequencies of 10 – 15 & 20MHz. The audio contained in the short transmissions was that of Bugs Bunny speaking or Yosemite Sam A. Bugs Bunny B. Yosemite Sam Answer B… Though signal strength here in South East England was poor, reception was possible and was best heard on 6500kHz. Monitors in the USA reported much stronger signals and were able to confirm that the speech was a clip featuring the voice of Yosemite Sam saying “…varmint – I’m a going to blow you to smithereenies”, which is an extract from the 1949 Bugs Bunny Cartoon “Bunker Hill Bunny”
The end of the story
The signals were particularly strong in New Mexico and on Wednesday 16 February 2005, and armed with a Potomac Field Intensity Meter, shielded loop antenna and a mobile rig the two hams set out West to track the signals.
At about 2.30pm local time the two Hams arrived at the Laguna Indian Reservation and approached a compound containing buildings, towers and antennas and were able to confirm that they had found the source of the transmissions, The MATIC Center.
