Huh. A Q meter. This interests me. Any ideas on where I could find
info
on building one of those? (I have a lot more time than money, and it
does
sound interesting...)
Thanks for the info.
Dave
This one is a nice design but needs an external signal generator.

I printed that article, and am puzzled by one thing. Some of the resistors
in the circuit diagram are labled things like "4k7" and "4m7." Is that 4.7K
or 47K? And 4.7Meg or 47Meg?
It does look like a good project, in spite of my earlier comments about the
"Poor Man's Q-Meter."
Thanks,
Dave
