UI-View is an APRS program developed by Roger Barker G4IDE (SK 9/8/04). This program is steadily gaining popularity
in North America, primarily because of unprecidented support by Roger and the fact it is likely the most stable windows based
APRS system in amateur radio today. Users may make their own maps using Street Atlas USA ("old style", not deluxe or current
"new style" versions), Streets and Trips, or Precision Mapping version 5,6 & 7 (which allows "zooming" much like APRSDOS or WINAPRS).
UI-View features an "open-ended architecture", allowing other people to write add-on programs to UI-View. There are several
add-ons available now. You may download the freeware version from the UI-View website. This version is almost 100% fully functional.
If you'd like, you may register the program
here. Though entirely voluntary, Roger's family requests that in lieu of a registration fee, any new registrations please make a donation to your national cancer research organization (in the USA, the American Cancer Society).
