WF3 Raprint System

The Raprint was a standalone unit designed by the Bureau that allowed tracking data from WF3 radars to be printed on a teleprinter along with elapsed time and radar status information.

Print intervals from 0.1 to 2 minutes, plus print-on-demand was selectable and an audible warning sounded for six seconds prior to printout for all but the shortest interval. An arbitrary two digit code was printed as set on two thumbwheel switches and a single digit code indicated whether the radar was under visual, Auto or manual control at the time of printout.

Units were used on radars at
Mascot
Canberra
Tennant Ck
Mt. Isa
Wagga
Mobile Met
Launceston

By the early eighties the 50 baud teleprinter was replaced with the first of a series of parallel printers. These were connected via a Baudot to ASCII converter.
