Radio Waves:\u00a0 Stories Making Waves in the World of Radio<\/h2>\n

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest\u00a0SWLing Post<\/em>\u00a0readers.\u00a0 To that end:\u00a0Welcome to the\u00a0SWLing Post\u2019s<\/em> Radio Waves<\/em>, a collection of links to interesting stories making waves in the world of radio.\u00a0<\/strong>Enjoy!<\/strong><\/p>\n

Many thanks to\u00a0SWLing Post<\/em> contributors Michael Bird, Seyfi Gen\u00e7, and London Shortwave for the following tips:<\/p>\n

\n

Can you hear me now: How pilots communicate with ATC while 35,000 feet in the air (The Points Guy UK)<\/a><\/h3>\n

When you\u2019re in a sealed, pressurised tube five miles above the ground, being able to communicate effectively is essential. In the early days of aviation, flags and light signals were used before designers were able to fit basic radio equipment into aircraft.<\/p>\n

Modern aircraft now have an array of communication devices from the rudimentary HF radios of old to sophisticated satellite-based systems that enable us to talk almost as if we were on a mobile phone.<\/p>\n

[…]The most common form of communication in aviation, very high frequency (VHF) radio calls are what we use for around 95% of our communications with ATC. In simplified terms, the transmitting station sends a signal that travels in a straight line and is picked up by the receiving station.<\/p>\n

VHF comms provide clear voice communications. However, as the radio signals travel in straight lines, they are limited by the curvature of the earth and objects that they may come into contact with, such as hills and mountains.<\/p>\n

The distance which a VHF signal can travel depends on both the height from which the signal is sent and the height of the receiving station. If both the sender and the receiver are on the ground, the distance will be relatively small. If both stations are in the air, the distance the signals can travel is much further.[…<\/a>]<\/p><\/blockquote>\n

Bushfire Research shows ABC Radio highly trusted and saves lives (Radio Info)<\/a><\/h3>\n

As the Bushfire Royal Commission continues, the ABC has released independent research that shows Australians turned to the national broadcaster in record numbers during the recent bushfire crisis.<\/p>\n

The research shows that the ABC was the most trusted information source during the fires and that lives were saved as a result of people acting on information the ABC provided.<\/p>\n

At the height of the bushfire crisis (31 December-14 January) ABC Sydney and ABC NSW local radio produced 296 hours of rolling\/continuous fire coverage, ABC Gippsland 134 hours, and ABC Melbourne 83 hours.[…<\/a>]<\/p><\/blockquote>\n

Did a Ham Radio Enthusiast Actually Speak to Crew Dragon? (Popular Mechanics)<\/a><\/h3>\n
\n

In a strange turn of events, a ham radio enthusiast in Gujarat, India falsely claimed to have made contact with NASA astronauts Bob Behnken and Doug Hurley during their historic journey to the International Space Station last weekend.<\/p>\n

Engineer Adhir Saiyadh told the Ahmedabad Mirror he decided to try to connect with the ISS as it sped over India and “coincidentally got connected to their frequency and received a response from one of the commandants of the capsule,” he said.<\/p>\n

But NASA says it simply isn’t true.<\/p>\n

Behnken and Hurley blasted off from NASA’s historic Launch Complex 39A on Saturday, May 30. After 19 hours in orbit, the astronauts docked with the ISS and reunited with fellow astronaut Chris Cassidy\u2014whose ham call sign is KF5KDR, by the way\u2014and Russian cosmonauts Anatoly Ivanishin and Ivan Vagner.<\/p>\n

“We did check with SpaceX to confirm that they were not aware of any communication with the astronauts via ham radio, and the crew did not report having received communication,” a NASA spokesperson told Popular Mechanics via email. “We are also under the impression that may be technically impossible for the Crew Dragon to communicate through ham radio.”[…<\/a>]<\/p>\n<\/blockquote>\n
