HamCalc nr 99 - Program för Radioamatörer

Den senaste versionen, nummer 99 av HamCalc "Painless Math for Radio Amateurs" finns att ladda ned från http://www.cq-amateur-radio.com/HamCalcem.html Det är drygt 300 program, allt i ett paket på mindre än 2 MB. Programmen använder uteslutande GWBASIC (medföljer) och körs utan mus. De samlade programmen innehåller i princip de mesta en amatör kan behöva för beräkningar. Programmen är intuitiva och fungerar nog även för de som inte använt datorn före Windows intåg! Läs mer i artikeln för exempel på meny och programinnehåll.
