AR Mag, Issue 6 2024 is out now !!

As promised in the last issue, this time we have two 50-year anniversaries to commemorate.
First up is the amateur satellite AO-7, which is the oldest man-made satellite still working!
It was launched on the 15th of November 1974!
It is older – I repeat, older – than the two Voyager spacecraft, both of which were launched in 1977.
The crux of the AO-7 story is that the satellite was conceived, developed, and constructed in home workshops and basements
by radio hams across Australia, Canada, Germany, and America.
AO-7 carried a range of radio science and space engineering innovations that were later adopted widely by other spacecraft
built by aerospace companies and organisations.
AO-7 – 50 years and still doing its thing.
Dont miss our feature, written by those involved – Rick Matthews VK5BGN, with Jan King VK4GEY, W3GEY.
The second 50th anniversary feature this issue is about Cyclone Tracy that devastated Darwin at Christmas 1974.
In a series of five articles over 16 pages, our writers detail the role amateur radio played in the immediate recovery
following the cyclones passing, along with experiences of “riding it out”, and of the aftermath.
The Cyclone Tracy feature is vividly illustrated, from the front cover to throughout the articles, including scenes of
violent destruction. Reader discretion is advised.
On technical matters, Lou Destefano VK3AQZ describes a smart, Arduino-controlled RF signal generator, while Jim Sosnin VK3JST
has an update on his Track-and-hold VFO for older rigs.
And to comfort our cabal of contesters, we have the annual lift-out, the 2025 Contest Calendar, printed in the magazines middle pages.
But, as usual, theres much, much more to read.
Amateur Radio magazine, Issue 6. More guts. Less gab.
Serving Australian amateurs since 1933.
Proudly produced and printed in Australia. Also available online.
Always published to a schedule, never random.
