Flight Inspection History Written by Scott Thompson - Sacramento Flight Inspection Office (May 2008)
Flight Inspection History Written by Scott Thompson - Sacramento Flight Inspection Office (May 2008) Through the brief but brilliant span of aviation history, the United States has been at the leading edge of advancing technology, from airframe and engines to navigation aids and avionics. One key component of American aviation progress has always been the airway and navigation system that today makes all-weather transcontinental flight unremarkable and routine. From the initial, tentative efforts aimed at supporting the infant air mail service of the early 1920s and the establishment of the airline industry in the 1930s and 1940s, air navigation later guided aviation into the jet age and now looks to satellite technology for direction. Today, the U.S. Federal Aviation Administration (FAA) provides, as one of many services, the management and maintenance of the American airway system. A little-seen but still important element of that maintenance process is airborne flight inspection. Flight inspection has long been a vital part of providing a safe air transportation system. The concept is almost as old as the airways themselves. The first flight inspectors flew war surplus open-cockpit biplanes, bouncing around with airmail pilots and watching over a steadily growing airway system predicated on airway light beacons to provide navigational guidance. The advent of radio navigation brought an increased importance to the flight inspector, as his was the only platform that could evaluate the radio transmitters from where they were used: in the air. With the development of the Instrument Landing System (ILS) and the Very High Frequency Omni-directional Range (VOR), flight inspection became an essential element to verify the accuracy of the system. -

The FCC Filing
Dr. Theodore S. Rappaport, PE PO BOX 888 Riner, Virginia 24149 [email protected] November 10, 2018 Commissioners Federal Communications Commission 445 12th Street, SW Washington, DC 20554 Dear FCC Commissioners: This is a notice of ex parte, based on email communication I had with the CTO of the FCC, Dr. Eric Burger, on November 8, 2018, his reply on November 10, 2018, and my reply on November 11, 2018. The email communication is centered around a posting that appeared on the FCC ECFS system on November 7, 2018, and is part of an ongoing proceeding at the FCC, NPRM 16-239, that I and thousands of others view as a direct threat to the national security interests of the United States, as well as being detrimental to the hobby of amateur (“ham”) radio. Public comments made in FCC’s NPRM 16-239, and in FCC proceedings RM-11708, RM-11759, and RM-11306 proposed by the American Radio Relay League, show the vast number of rule violations and national security threats that continue to go unaddressed by the FCC. Commenters such as me view the lack of FCC acknowledgement of these problems as jeopardizing the safety of US citizens. NPRM 16-239 attempts to remove a limit on the baud rate of High Frequency (HF) shortwave transmissions, without first addressing ongoing rule violations pertaining to proper usage of the amateur radio service, the use of obscured, private messaging which is forbidden in Part 97 rules and creates national security concerns, as well as other violations. If allowed, NPRM 16-239 would perpetuate the current violations, and would authorize obscured transmissions of unlimited bandwidth over the global airwaves, further increasing the danger to our national security, since these transmissions cannot be intercepted or eavesdropped by other amateur radio operators or the FCC. -

Signalling and Beacon Sites in Dorset
THE DORSET DIGGER THE NEWSLETTER OF THE DORSET DIGGERS COMMUNITY ARCHAEOLOGY GROUP No 43 December 2016 Signalling and Beacon Sites in Dorset Richard Hood has kicked off this new project. He needs somemorevolunteerstohelpwith the research Introduction The ability to send or receive a message over a distance to warn of impending attack has been used to mobilise troops for defence since the Roman times. The Romans developed a system using five flags or torches to carry a simple message over short distances. This was usually used in battle to pass information out to army commanders. To carry a simple message further, a bonfire was used set on a high point, usually from a mini fort within vision of one or more other sites. This type of warning system was used during the invasion of Britain, when vexation forts could come under attack from tribes yet to be persuaded of the advantages of Roman living. Near the end of the Roman occupation signal stations were employed on the East and South coasts to warn of Saxon pirates. Roman signal stations on the NE coast of England took the form of mini forts, with a ditch and bank for defence. Black Down in Dorset, excavated by Bill Putnam and re examined by Dorset Diggers in 2016 is of this type. The Saxons appear to have had a system of inter divisible beacon sites to warn of Viking attack from the ninth century onwards. Later, beacons were erected to warn of the approach of the Spanish Armada, followed by a similar, but unused system, to warn of Napoleonic invasion. -

Advantages and Limitations of Li- Fi Over Wi-Fi and Ibeacon Technologies By
ISSN (Online) 2321 – 2004 IJIREEICE ISSN (Print) 2321 – 5526 International Journal of Innovative Research in Electrical, Electronics, Instrumentation and Control Engineering ISO 3297:2007 Certified Vol. 4, Issue 11, November 2016 Review Paper: Advantages and Limitations of Li- Fi over Wi-Fi and iBeacon Technologies By Deepika D Pai Asst. Professor, (Sel Grade), Department of Electronics and Communication Engineering. Vemana Institute of Technology Abstract: Li-Fi can be thought of as a light-based Wi-Fi. That is, it uses light instead of radio waves to transmit information. And instead of Wi-Fi modems, Li-Fi would use transceiver-fitted LED lamps that can light a room as well as transmit and receive information. Light is inherently safe and can be used in places where radio frequency communication is often deemed problematic, such as in aircraft cabins or hospitals. So visible light communication not only has the potential to solve the problem of lack of spectrum space, but can also enable novel application. The visible light spectrum is unused; it's not regulated, and can be used for communication at very high speeds. This paper compares the Li-Fi technology with Wi-Fi and iBeacon technologies. Keywords: Li-fi, Wi-Fi, iBeacon, visible light communication, BLE communication I. INTRODUCTION In recent trends, wireless communication Wi-Fi is gaining government licence. This new Ethernet standard was tremendous importance. CISCO reported that the compatible with devices and technology working on radio compound annual growth rate (CAGR) of mobile data waves and came to be known as ―Wi-Fi‖ only in 1999. usage per month is around 80% which has led to the saturation of the network spectrum consequently bringing iBeacon: The technology was first introduced by Apple at down its efficiency. -
TMRA Amateur Radio Beacon April 2020
TMRA Amateur Radio Beacon April 2020 From Rob, KV8P News from the President – April 2020 Hi everyone. All I can say is, "wow". Who knew we'd all be in this position, having cancelled our 2020 Great Lakes Convention and TMRA Hamfest and now looking at cancelling many of our other events early this spring due to this global pandemic COVID- 19 Virus? I don't even know what to say. I just hope everyone is protecting themselves and staying home during this time. We'll get back to normal soon enough. Relax/Breathe! I feel like sharing the meme I saw I facebook the other day where someone mentioned, "Ok now, that thing someone found in Area 51 recently? Yah, please put it back!". haha So, some related updates. We obviously won't be meeting for anything "in-person" right away until given direction by our elected officials to do so. Therefore, I'M NEWLY LICENSED, NOW WHAT" CLASS - Originally scheduled for April 18th is cancelled. We'll pick this one up again next fall. 1 GENERAL MEETINGS: We'll only be holding on-the air Nets on 147.270 (and linked repeaters) in lieu of General meetings until then. Please watch for updates going forward as, starting in May we also may add some facebook live programs and/or zoom programs as well. Please check into our nets on the 2nd Wednesdays at 7pm for some updates. We'll be discussing our next likely operation for Museum Ships on the air in early June during the April net.
