Longest-Serving Satellite OSCAR-7 Marks 50 Years in Orbit:

by AB7RG  2024-11-13
Launched on November 15, 1974, OSCAR-7, a microsatellite, continues its mission 50 years after its launch, serving as a vital asset for amateur radio operators globally. It holds the title of the oldest operational satellite, predating the launch of NASA's Voyager 1 and Voyager 2 by three years. OSCAR-7 belongs to a series of amateur radio satellites known as OSCARs (Orbital Satellites Carrying Amateur Radio), built by volunteers from the Radio Amateur Satellite Corporation (AMSAT). Many of these contributors have affiliations with significant U.S. space organizations such as the Goddard Space Flight Center. AMSAT's innovation led to the novel use of secondary payloads to stabilize the center of gravity during launches. Despite being constructed primarily on basement workbenches by AMSAT volunteers, OSCAR-7 had to meet rigorous space-readiness standards to be integrated alongside the primary payload, NOAA-4/ITOS-G. Engineered with CMOS technology, OSCAR-7 was initially projected by NASA engineers to last just one to three years due to its non-radiation-hardened components. However, the satellite not only outlasted its expected lifespan but also contributed notable advancements. It enabled early ground-to-satellite-to-satellite-to-ground communications by orbiting close to its predecessor, OSCAR-6, facilitating unique message relays between satellites.

Boca Raton WWII Vet's Unique Skill as Teenager Kept Him Off Front Lines:

by AB7RG  2024-11-12
BOCA RATON -- Arthur Polacheck still remembers receiving the message, in Morse code, that World War II was coming to an end. "I was privileged to get a code that the Japanese were at the point of calling it quits," he said. He was 17 years old and stationed in Okinawa, an island of Japan, as a radio operator for the United States Army. At the time, he knew that if he'd waited until he turned 18, he would have been immediately drafted as a foot soldier into the army. "I had skills," said Polacheck, 96, who lives in Boca Raton and has lived in South Florida for the past 40 years. "I thought I could better serve my country in a field that I was very well-versed in. Electronics and radio repair." He'd spent three of his teenage years building up those skills. Since he was 15, Polacheck had his own ham radio station (the use of the radio frequency spectrum for non-commercial message exchanges) -- he'd earned his license for it and was permitted to operate it on two wavelengths.
