The Very Large Array (VLA) near Socorro, New Mexico

DC5DP Antenna

Launched in December 1961, OSCAR 1 (Orbiting Satellites Carrying Amateur Radio) was the world's first non-governmental satellite.

On December 12, 1901 Guglielmo Marconi succeeds in sending the first radio transmission across the Atlantic Ocean, disproving detractors who told him that the curvature of the earth would limit transmission to 200 miles or less.

The Drake TR-7, introduced in 1978 as part of its new "7-Line" series of solid-state equipment. Before the name TR-7 was chosen, Drake engineers called the project the 700 System. Marketing changed it to TR-7 to match the classic Drake naming style (like the R-4/T-4 line).

The Yaesu FT-290R and FT-690R portable multimode radios from the early 1980s. Released around 1982, the FT-290R gave hams a small, carry-around radio that worked in four modes: FM, USB, LSB, and CW. A couple of years later, Yaesu released the FT-690R, which worked on the 50 MHz “magic band.”
