Former USAF Dye-3 (Icecap2) DEW radarsite. Ops in 1961 and stayed ops until it went in caretaker status in 1990. Site used radio callsigns: Panfish and Sobstory.
Primary Search Radar for all 4 DEW Line sites in Greenland was the Bendix AN/FPS-30; this long-range searchradar was originally called "Sentinel" radar. Once planned as a replacement for all aging AN/FPS-19 DEW-Line radars, the AN/FPS-30 was installed in 1961 only at the 4 Greenland "DYE" radarstations. It operated at 570 to 630 MHz with a peak power of 150 kW and an average power of 3 kW.
The AN/FPS-30 radar's pulse-repetition frequency (PRF) was 500 pulses/sec and the antenna aperture was 45 ft. x 25 ft.
The transmitter output tube was a Klyston with 62-dB gain.
