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?

The company that made ARRL Designer (Compact Software) was bought by Ansoft.
They have greatly enhanced the capability, and the current offering is
available as a free student version he
http://www.ansoft.com/ansoftdesignersv/
There are also many other evaluation & student packages available on the net
for free. Check out this site as a starter:
http://www.rfengineer.cc/rftools.htm

Also, if you do an internet search on "RF circuit analysis software" or
something similar, you'll get lots of hits.

BTW, I run ARRL Designer under Win98SE and it's fine. What OS are you trying
to use it with?

Joe,

Thanks for all the resources. At my house ARRL Designer pukes and dies on
both WIN98 (500MHz P2) and WIN-XP (2.5GHz P-4) machines.

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.......

73, Leo

Thanks Leo,

Mine is the original version 1.0 and it doesn't run in Win98 or Win-XP Pro
or Win-XP Home.

I'll see if I can root out a copy of 1.5.

Zero cost ought to be attractive? :-)

Linear Technology Corporation has a free download version of their

LTspice / SwitcherCAD III at

http://www.linear.com

This is a standard SPICE plus the addition of switching power supply
section (using Linear's PSU ICs of course). The SPICE part runs the
same as everyone else's SPICE which has been optimized for speed
of execution.

Mine runs fine on a Windows 98 platform...as well as the Windows
XP on my wife's H-P machine.

The SPICE core is total freeware and that was Pedersen's request at
Berkeley. Other folks have taken the free core and established their
own Windows menus, pop-downs, and output formatting; that part is
individually copyrighted...like copyrighting fancy wrapping paper for a
present. :-)

"Radio Designer" has a SPICE core.

There are several SPICE "lite" versions available for free as demos, all
with "limited" component count, number of nodes, etc., etc. Those
limitations do not hinder a complex several-transistor plus several
standard IC circuit combination analysis. You can even get freebie
CDs in the mail on request of these demo versions. I have such as
well as the SPICE core source code in both C and FORTRAN.

If you are only interested in frequency-domain circuit analysis and
want an on-screen simulation circuit control (add, delete, insert,
modify values) along with some macromodels within, I can send you
my (formerly) shareware version of LINEA. LINEA is DOS-level,
looks monochrome, is not attractive in looks but the answers are
on-the-money out to double precision. At DOS level operation, it is
relatively immune to Windows versions' differences; LINEA was
originally written on a Spectra 70 mainframe and eventually ported
to a PC running Windows 3.1 at DOS level. LINEA is very small as
program packages go, roughly 150 K...pretty cosmetics take up
many megabytes.

Yup!

I downloaded Ansoft "Designer SV" which Joe recommended. (At 77.0 MB!)

Looks a lot like the old ARRL package, but 10 years newer.

Thanks for your recommendations. (Filed away for a look if the Ansoft
package isn't a fit.)

I hear you. I have several older (DOS) comm programs which puke on
faster machines - good ol' PCPLUS for one. That's why my 24/7 packet
circuit (for the local ARES/RACES group) runs on a separate (166
P1) machine - it slows down my Athlon XP 2000 and my P2 machines.

I'm trying to find a DOS emulator for Linux to see if I can run two
circuits at once now...,..

A version of F6FBB is available which runs native on Linux, using the
Linux AX.25 networking support code. There ought to be no problem
running multiple TNCs (either real ones in KISS mode on serial ports,
or soundmodem versions), doing digipeating, etc. on Linux.

Phil,

Don't know if it will help, but how about this:
http://www.dosemu.org/
I have no idea if it will help or not; I'm thinking of putting Linux in one
of the boxes. A Google search of 'DOS emulators for Linux' yielded a ton of
hits, but you've likely already researched them.
