HF Aeronautical bands

There is still plenty of activity on the HF Aeronautical bands. You can listen to civil and military aircraft every day with just some frugal hardware. Whether you are using a Software Defined Radio (SDR), an old school HF receiver, or utilizing a WebSDR, there is plenty to monitor when you know where to look.

Thew below video will give you the basics of where to find the Aviation Communications that take place from 3-30 MHz (HF / Shortwave). The video  covers VOLMET broadcasts, the Major World Air Route Areas (MWARA), and Military Nets like the US Global Communications System (HFGCS). Remember, these signals travel thousands of miles. It can be quite exciting to receive them over such great distances. When editing this video I was listening to a VOLMET station in Auckland, New Zealand – a distance of over 7500 miles (12,200km) away!

June 2021 Annular Solar Eclipse

HamSCI is looking for ham radio operators to make recordings of time-standard stations during the June 2021 annular solar eclipse across the Arctic Circle as part of a citizen science experiment. Researchers will use the crowd-sourced data to investigate the superimposed effects of auroral particle precipitation and the eclipse on HF Doppler shift.

Participants would collect data using an HF radio connected to a computer running open-source software. A precision frequency standard, such as a GPS-disciplined oscillator, is desired but not required to participate. Radio amateurs and shortwave listeners around the globe are invited to take part, even stations far from the path of totality.

Last year’s eclipse festivals included more than 100 participants from 45 countries. The experiment will run June 7 – 12. All participants will receive QSL certificates and updates as the data is processed. This is a pilot experiment for HamSCI’s Personal Space Weather Station project, which seeks to develop a global network monitoring the geospace environment. For more information and set-up instructions, visit the June 2021 Arctic Eclipse Festival page on the HamSCI

WARC – Use them or lose them

The World Administrative Radio Conference (WARC) bands are three portions of the shortwave radio spectrum used by licensed and/or certified amateur radio operators. They consist of 30 meters (10.100–10.150 MHz), 17 meters (18.068–18.168 MHz) and 12 meters (24.890–24.990 MHz). They were named after the World Administrative Radio Conference, which in 1979 created a worldwide allocation of these bands for amateur use. The bands were opened for use in the early 1980s. Due to their relatively small bandwidth of 100 kHz or less, there is a gentlemen’s agreement that the WARC bands may not be used for general contesting. This agreement has been codified in official recommendations, such as the IARU Region 1 HF Manager’s Handbook, which states: “Contest activity shall not take place on the 10, 18, and 24 MHz bands.”

The USA (Region 2) limits amateur radio users to 200 watts peak envelope power on this band.

Active Atlantic Hurricane Season

The Atlantic Hurricane Season, which starts on June 1, promises to be a busy time for amateur radio volunteers on the Hurricane Watch Net (HWN) to report ground-level storm conditions in real time for use by National Hurricane Center (NHC) forecasters, and for SKYWARN volunteers, many of whom are hams. The National Oceanographic and Atmospheric Administration (NOAA) has forecast a likely range of 13 to 20 named storms (winds of 39 MPH or greater), of which six to ten could become hurricanes (winds of 74 MPH or greater), including three to five major hurricanes (Category 3, 4, or 5, with winds of 111 MPH or greater) expected. NOAA projects these ranges with a 70% confidence level.

“2021 is looking to be another active season,” said HWN Manager Bobby Graves, KB5HAV. “We can only hope we don’t have a repeat of 2005 or 2020. The sea surface temperatures throughout the normal areas of tropical cyclone activity are already near or just above 80 °F, just what storms like. The current forecast for 2021 is on the high side. The adjusted average is 14 named storms, with seven hurricanes and three of those at Category 3 or stronger.”

When activated, the HWN operates on 14.325 MHz during daylight hours and on 7.268 MHz after dark. When required, however, the net will use both frequencies simultaneously.

 

The net’s primary mission is to disseminate tropical cyclone advisory information to island communities in the Caribbean, Central America, along the US Atlantic seaboard, and throughout Gulf of Mexico coastal areas. It collects observed or measured weather data from participating radio amateurs in storm-affected areas as well as any post-storm damage reports and passes that information along to forecasters at the National Hurricane Center via its amateur radio station, WX4NHC. The HWN typically activates whenever a storm system has achieved hurricane status and is within 300 statute miles of a populated landmass — although this can vary according to the storm’s forward speed and intensity or at the request of NHC forecasters.

LightCube – A Fun Ham Cubesat

The ASU CubeSat, named LightCube, is about the size of a toaster and will be deployed to low-Earth orbit (LEO). Its unique feature is that it can be commanded by anyone with an amateur radio license and a ham radio to set off a xenon flash from the spacecraft that will be visible from the ground.

“The public will be able to track the LightCube satellite using an app, then transmit to the satellite with a ham radio. Once the signal has been received, they will see a flash from the satellite in the night sky,” said Principal Investigator Jaime Sanchez de la Vega, of Vega Space Systems, who graduated in 2019 from ASU with a double major in aerospace and electrical engineering from the Ira A. Fulton Schools of Engineering.

“This is an education-based mission,” said Jacobs, who is also an assistant professor at ASU’s School of Earth and Space Exploration. “Our goal in building and launching a spacecraft that can be commanded by the public is to inspire everyone to learn about telecommunications, spacecraft design, atmospheric and climate science, and orbital mechanics.”
