Hi Jack,

Thanks for posting this. It looks very interesting, but the .exe file seems
to be a DLL for Visual Basic 6.0 and not the main program. I searched the
article for more references to .zip and .exe, but couldn't find any. Do you
have any more information on where to obtain professor Steber's program?

Regards,

Mike Monett

I've check the QEX article but I've found that the minimum C or L range
is very hight for my needs

Thanks Paolo Iw3arv

OK, I found it. It's http://www.arrl.org/qexfiles/LMSProg.zip

(Also, more good stuff to check at http://www.arrl.org/files/)

The zip is very short - 51k, but it contains the program and some auxilary
files. The program ran instantly on my Win98 computer. The VB DLL was
already installed in \windows\system from previous downloads.

Jack, this looks very interesting and easy to do. Thanks for posting the
url.

Regards,

The Columbus, Ohio QRP Club did a group build of an LC meter based on
the project in "Everyday Practical Electronics" magazine, February
2004 issue. The URL is http://www.qsl.net/cqrp/projects.html.

For some reason, the link to the members' meters is no longer working.

This meter has slightly better capacitance range specs than the AADE
meter, as reported by ARRL on the website awhile ago.

If you are interested, I am building this meter, and I can give you
some additional information about it. Please email me directly,
removing the ** from my email address.

Regards,
Ted KX4OM
