ARRL Radio Designer

Introduction

ARRL Radio Designer is an obsolete software program for circuit modeing sold between 1994 and 2000.  We were forced to discontinue it, as the new owners of the company that produced it declined to recompile it for new operating systems.  While it runs fine on Windows 3.1 and 95, it should not be expected to be compatible with Windows Millenium edition.  For about 10 years, they provided a rather functional student demo version for hams for free.  But, they have recently switched to low cost site licenses of their full featured software to institutions, so demo versions are no longer available.  Thus, hams may wish to run this old software on legacy hardware.

This archive of resources is intended to help  hams running ARD on older machines--Microsoft has discontinued support for 16 bit software on all their 64 bit products--ARRL Radio Designer will not run under x64 XP, x64 Vista, or x64 Windows 7.
