Robert Sickels, an amateur radio astronomy pioneer.
SETI Pioneer Dr.Paul Horowitz and Jeffrey Lichtman at Green Bank
The 85 foot antenna (one of two 85 footers) is at the Old Rosman NASA
site in North Carolina.
This will be the Pisgah Astronomical Research
Institute (PARI), January 1999.
Notice L Band Choke and Feed on mounting plate.
15ft Dish at PARI with RAS Choke and Feedhorn
Rack Mounted Ultra Cyber
The Ultra Cyber is shown as it is recording data from the 85-1 antenna.
The Ultra Cyber is a "SETI Capable" radio telescope receiver.
