EME or Moon Bounce Began 70 Years Ago:

The United States Army was the first to bounce a radio signal off the Moon,
and the site is now part of the Information Age Science History Museum and
Learning Centre. The historic transmission on January 10 1946 from an Army
tracking dish, is the starting point for all moon bounce experiments.
Project Diana, named for the Roman Moon goddess Diana, was an experimental
project at Fort Monmouth in New Jersey to bounce radar signals off the Moon
and receive the reflected signals. It played a part in the space race, and
even those weak signal reflected from the lunar surface are reported to
have had experimental applications in spying activities. Those lucky enough
to receive the reflected signal received a QSL card. Moon Bounce
communication was abandoned by the military to be replaced by communication
satellites in the early 1960s. However it found a use in Amateur Radio in
the 1960s and with weak signal techniques of today is still being explored
throughout the world.

A technical solution to fix spurious emissions that sometimes come from the
National Broadband Network or NBN fixed wireless network has been found.
Steen Jensen VK7AP has raised the issue of severe interference to high
frequencies, medium wave broadcasts and fire alerts in rural areas of
Tasmania. Chris Holliday VK7JU in Deep Bay Tasmania also reports the same
problems, and it may occur elsewhere with a particular brand of fixed
wireless network device. Steen VK7AP thanked the WIA for its
representations including statements to the ACMA backed up by Standard
Australia compliance, and VK7WI broadcast publicity by Justin Giles-Clark
VK7TW.

Aluma Tower is Hard at Work Re-Inventing Itself in Vero Beach:

Every day Aluma Tower Company manufactures portable aluminum towers,
shipping them across the country and around the world. This multi-million
dollar manufacturing business has been located in the center of Vero Beach
on Old Dixie Highway for the past 40 years. Yet chances are you've never
heard of it. You can easily drive by Aluma Tower's two locations and never
notice either one. Angela Ledford, president and general manager, calls her
company "a hidden gem." Vero Beach customers include radio stations, ham
radio operators, farms and citrus groves, as well as the water treatment
and power plants.
