There is a good reason why telecoms companies have gone to undersea cable, rather than satellite, and due to bandwidth requirements, rather than costs.

Another technology gained attention in the aftermath of the Malaysia Airlines disaster: a “live black box,” one that could stream data (or voice) in real time to the ground. Technologically, it’s possible, but the concept has been slow to catch on. The expense of outfitting airplanes would be prohibitive, without even considering the associated costs and logistics of overseeing such a large amount of data, from staffing to updating processing and storage systems on the ground.

A less expensive and less data-heavy option might be to wire airplanes to emit so-called “triggered transmissions”—a system by which certain parameters are transmitted only when sensors detect something has gone awry. So if an airliner’s altitude or airspeed suddenly changes, its special transmitter automatically starts sending live data via satellite to the ground.

Spurred by the MH370 mystery, the International Civil Aviation Organization has recommended that more aircraft be equipped with live streaming and ejectable recorders. The ICAO, the United Nations agency that sets global aviation standards, in March 2016 approved a proposal for all newly designed aircraft to carry tracking devices that can transmit their locations at least once a minute in an emergency. Minute-by-minute reports should provide investigators with a much narrower search area for downed aircraft—just slightly more than 100 square miles. But this and other recommended practices don’t go into effect until 2021 and, even then, they won’t cover the thousands of airplanes currently in the air.

One of these solutions may work for you. I think TIVO is more refined than everyone else. They started this whole DVR thing. I got my first Tivo back in 1999.

The Kiowa County Commissioners regular meeting on April 25, 2019 was called to order by Chairman Richard Scott. Robertson opened the meeting with prayer and the Pledge of Allegiance. Those in attendance:

The international award-winning musical Come from Away has been packing in record-breaking audiences both on Broadway and in the West End. To ensure discrete, high-quality sound reinforcement on the show, sound designer Gareth Owen has specified the new ultra-compact Sennheiser SK 6212 bodypack transmitter for all cast members.

Several companies currently offer such services, including Calgary-based FLYHT, which has contracted with more than 70, mostly small, airlines and equipment manufacturers worldwide. The company’s Automated Flight Information Reporting System (AFIRS) can be retrofitted to aircraft for an initial outlay of $30,000 to $60,000, depending on its configuration, according to FLYHT CEO Thomas Schmutz. AFIRS is an Iridium-based SATCOM device that transmits data to the ground in real time, where it is then processed and distributed to subscribers through FLYHT’s ground server network. The service offers the same data acquired by the airplane’s flight recorder, providing carriers with up-to-the-minute information if there’s an emergency or, more generally, with data about how their airplane is performing. If a fault needs to be fixed, ground crews can be waiting when the airplane lands. Schmutz says FLYHT, which started operations in 1998, has seen an uptick in interest for its products after the incidents of the last decade. The company has partnered with recorder manufacturer L3 to offer its technology in future Airbus A320 airliners. But airlines haven’t been beating down the doors for AFIRS—at least not yet.

The Hempcoin (THC) is down by more than 5% in the last 24 hours as the crypto coin reached $0.016. According to CryptoBeat, the Hempcoin (THC) can reach $0.01 if the current crypto market decline continues.

For those who aren’t electrical engineers or didn’t live through the dial-up era, I’ll explain the issue of bits-per-symbol. With non-baseband transmission, the signal that we want to get across is modulated on a carrier. This way, every transmission can have its own frequency without getting in the way of anyone else. However, every time there is a change in the data signal, this distorts the purity of the carrier, making it spread out across the frequency band. The extent of this invasion into neighboring frequency space is determined by the frequencies in the signal that we modulate onto the carrier, which in turn depend on how often per second we change the data signal.

In addition to his Wisycom gear, Lawrence’s personal kit consists of DPA d:screet 4061 mini lavaliers and Sanken COS11 as well as a Sound Devices 633 recorder and 688 mixer, with six channels of Wisycom inputs. On cart jobs, he runs an RF Venue Diversity Fin antenna into a passive splitter to feed Wisycom transmitters.
