QRPPAL, developed by WB2QAP, functions as a freeware QRP logging application for Windows 3.1 and Windows 95, initially introduced at the 1996 Dayton Hamvention FDIM QRP symposium. The software integrates the original "Logger" program, which was specifically designed for ARCI contest dupe checking and logging, alongside versions tailored for NW-QRP, MI-QRP Club, and Colorado QRP Club contests. It is distributed as a self-extracting archive, _qrppal!.exe_, approximately 1.2 MB in size, which unpacks _qrppal.exe_ and _setup.exe_ for installation. The program's modular design incorporates extensive QRP-centric databases, covering ARCI awards, QRP club listings, QRP periodicals, kit/vendor directories, and detailed rig reviews, often with photos. Noted reviewer Bob Gobrick, _VO1DRB_, described it as a "QRP Internet Web Site in a box" due to its comprehensive data modules, which are also user-modifiable. Installation involves running _setup.exe_ to create batch files like _setup95.bat_, which then establish a c:\qrppal directory and deploy the program files. Users initiate the application by typing "qrp pal.tkn" after setup. The Colorado QRP Club contest version should be avoided due to specific first name exchange requirements not supported by that module.
