a summit. Summit to summit contacts attract bonus points, as does operating certain summits during pre-defined Winter periods. Certificates are issued at point intervals. Other variants of this radio-sport along the same lines exist, for example WWFF (World Wide Flora and Fauna in Amateur Radio) where activators set up a station in a nature area and chasers contact an operator who is in the nature area. RaDAR (Rapid Deployment of Amateur Radio) Originally called SIAS (Shack in a sack), this radio-sport combines speed, a portable station and efficient communications. The operator picks a four hour time-frame within which to operate and deploys their portable station as quickly as possible. Once deployed, the operator makes a maximum of five contacts, exchanging name, signal report and exact (8 digit or more) maidenhead location digits. Once five contacts have been made, the operator packs up the station and moves it at least 1 km on foot or 6 km by car. Other modes of transport are also used, each with its own minimal distance. The operator then deploys their station at the new location, makes five more contacts, packs up and moves again, until the four hours are up. The operator with the highest contact count at the end of the day, for their chosen four hour period of operation, wins. High Speed Telegraphy High Speed Telegraphy competitions challenge individuals to correctly receive and copy Morse code transmissions sent at very high speeds. International competitions typically involve several events, some of which are based on simulations of amateur radio activity. One event in the Radioamateur Practicing Tests (RPT) uses a computer program that sends amateur radio call signs at high speed for a specified period of time, and generates a score for the competitor based on errors in copying. Another event is the "pileup" competition, where competitors must copy as many individual call signs as possible while many are being sent simultaneously over a defined period of time.
