I have a copy of the old ARRL "Radio Designer" software, but it does not run on modern OS's, and ARRL has not renewed their agreement with the author.

Can anyone recommend a similarly capable software package which will run on an XP platform. Need not be freeware, but also cannot afford a professional 'commercial' package.

Suggestions?
