ARRL Radio Designer was published by ARRL beginning in late 1994. It was discontinued in August 2000 and is no longer available.

A subset of the industry-standard linear circuit-analysis program Super-Compact from Compact Software, ARRL Radio Designer is a Windows(TM)-based computer program that simulates and analyzes the performance of passive and small-signal-ac radio and electronic circuitry.

Since ARRL Radio Designer was first published, Compact Software has been acquired by Ansoft Corporation, and Super-Compact has been replaced by Serenade, an integrated software suite for RF and microwave design. Ansoft Corp. offers a student version called Serenade SV for personal, noncommercial use. Serenade SV offers many of the features of ARRL Radio Designer (and more) in a more modern software package. You can find out more about Serenade SV and download a free copy from Ansoft's Serenade page. ARRL is not affiliated with Ansoft Corp. We provide this information as a service for ARRL members who are interested in circuit modeling software, but cannot offer support for Serenade SV.
