US OMEGA navigation transmitter operated by the US Coast Guard (in the U.S.A.) and other countries around the world. In the frequency range above 10 kHz, the signal could be heard as a repeating series of tones. Each of the seven OMEGA stations transmitted a unique pattern of four tones that repeated every ten seconds. OMEGA ceased operation in September 1997, done in by the advent of global positioning system (GPS) technology. Document IMAGE/INSPIRE.

Signal emitted by the famous Sputnik 1. Recorded at 20,007 MHz on October 7, 1957 at 0457z by Roy Welsh, W0SL (then W5SLL) from Dallas using a military surplus AN/FRR3A HF RTTY receiver. W5SLL used a fixed antenna cut for 108 MHz and a VHF converter. The antenna was a six-element colinear array constructed on a 33x33 cm (13 by 13 ft) wooden frame and suspended above a "chicken wire" reflector. The whole array was placed on the roof of the house heading at about 75° above the southern horizon. Satellites were captured as they flew through the main lobe of the array. W5SLL is considered as the first amateur having provided historical recordings of artificial satellites.
