Amateur radio can open up a new world of opportunities for students, says teacher Chris Aitken MM0WIC, @skipperAitken on X, who shares his tips on how to start a club in the Times Educational Supplement – TES Magazine.

“In 2023 I officially started the Wick High School Radio Club, with a callsign of GM0WHS. The aim of the club was to expose our students to the wide range of activities available in amateur radio.

I remember our first activity: talking to another amateur in England via the SO-50 satellite. I stood with three students on the rugby pitch, antennas pointing to the sky and talking to another amateur, Nick M1DDD.

By the end of the contact, we had 30 students around us wondering what was going on. Their curiosity sparked, we answered questions on what we were doing and invited them to take part.”

Amateur Radio Satellite Operation in Algeria

Abdel Mesbah M0NPT reports on what is believed to be the first amateur satellite operation from Algeria since the 7X0DX activation in 2002.

An introductory training course on amateur satellite traffic which was organized on April 14-15, 2017 at the 7X3WPL radio club in Laghouat (400 km south of Algiers).

This course was held under the auspices of the Laghouat Youth and Sports Directorate, Laghouat’s League of Cultural and Scientific Activities for Youth (LACS), the National Association of Algerian Radio Amateurs (ARA) and The El Manar youth hostel which houses the radio club 7X3WPL.

A total of about 25 students took part in this event, mainly students in master telecommunications and other enthusiasts of the world of radio telecommunications. While communication and demonstrations on amateur satellite traffic were carried out by Abdel Mesbah M0NPT, a member of AMSAT-UK and Chairman of the Hucknall Rolls-Royce Amateur Radio Club (UK), the Doppler management in satellite traffic was discussed by the Professor researcher, M. Bouzouad Mouloud of the laboratory of telecommunications of the signals and systems of the University of Laghouat.

The radio club 7X3WPL is in the process of installing a satellite station using a Kenwood TS2000, Yaesu G5500 Trackers and Wimo cross Yagis, please keep your ears open on Satellites as you may hear them soon.

I am delighted to be the first person to have activated Algeria (7X2ARA in JM16MS & 7X3WPL in JM13KT) on the SO-50 satellite and I am looking forward to going back again.

The first contact from Algeria on the SO-50 satellite was with my friend Peter 2E0SQL [now 2M0SQL], followed by Adam MU0WLV, Fran EA1JM, Olivier F5RRO, Jerome F4DXV, George MI6GTY, Peter G0ABI, Neven 9A5YY, Colin MU0FAL and many others.

I am also looking forward to install my own station in Algiers once I get my Algerian callsign 7X2TT sorted Inchallah

HamRadioNow: Look! Up in the Sky!

Look! Up in the Sky!The bulk of this episode is an on-location interview with two Raleigh NC area hams who gave a couple of live demonstrations of operating through satellites at the Raleigh Hamfest, April 15,  2017.

There’s some banter between hosts David Goldenberg W0DHG and Gary Pearce KN4AQ back in the studio. And toward the end Gary announces a Viewer Challenge that we’ll detail down below.

The satellite hams are John Brier KG4AKV and Tucker McGuire W4FS. At 18 years old, Tucker is a relatively new ham who first started operating satellites last summer, and quickly jumped into the deep end. John’s been around longer, but ham radio satellites and space operation captured his focus, too. He produces videos about it on his YouTube channel, Space Comms. Links below.

Gary talked to John and Tucker after they completed their second demo, and he edited a little of each demo into the interview.

There’s video of all of both demonstrations on YouTube. John shot himself operating through ‘Saudi-Sat’ SO-50, a “Mode J” FM crossband repeater (145.850 MHz uplink and 436.795 MHz downlink). John used three cameras (including a GoPro on a headband for a unique view). Gary edited the video and put it on the HamRadioNow YouTube channel as an extra bit if video.

Gary added two more cameras to the mix to shoot Tucker operating through FO-29, a Japanese satellite that uses a 100 kHz wide ‘linear transponder’ for mostly SSB and CW (and NO FM, please) between two meters and 70 cm. There’s a few minutes of that demo in this episode, and the whole thing is on John’s Space Comms channel.

Christian Jacobs 2E0ICL has also released a video of his recent FM contact via the SO-50 satellite during a recent Summits On The Air (SOTA) activation at Walbury Hill (summit identifier G/SE-001).

A total of 13 contacts were made, mostly on 2m SSB, including some FM satellite working via SO50 with 10 watts to an Arrow dual-band antenna.

Mike Parkin, G0JMI, will give a talk entitled: Amateur Radio Satellites: A General Overview and Understanding of FUNcube-1 (AO-73) and Saudi-Sat 1c (SO-50).

Satellite operation is not quite as daunting as it can at first appear, and Mike will enlighten the audience with some of his experiences, as well as the equipment and techniques used for satellite communication.

Doors open at 7:30 pm for 8:00 pm on Monday, January 26, 2015 at the Crondall Scout Hut, Pankridge Street, Crondall, Farnham, Surrey, GU10 5RQ. As usual the kettle will be on to provide the refreshment.
