Hans,

ARRL's Radio Designer Version 1.5 (copyrighted 1998) claims that it
runs on both Windows 9x amd NT systems, and I can confirm empirically
that it operates on Win XP Pro as well - an excerpt from the included
Help file is below:

" ARRL Radio Designer 1.5, a Windows (3.1, 3.11, 95 and NT)-based
computer program, lets you create computerized models of audio, radio
and electronic circuits so you can see how they work--and make them
work better--without actually building them....."

IIRC correctly, the last version sold by the ARRL was 1.51. If you
are using an older version, perhaps you can find a copy of this one
somewhere? Was originally $150, should be a copy at a fraction of
that out there now that it is discontinued.......

Several years ago ARRL marketed a WIN3.xx software package called "Radio
Designer" which was a 'lite' copy of a commercial RF design program.
Unfortunately the program does not run under 16- and 32-bit Windows
environments, and the OEM is not interested in entering into further
arrangements with ARRL.

Does anyone know of a similar program in a price range (under $500)
attractive to hams?
