I was surfing the net and found a reference to an unusual low phase
noise LC VFO that uses two inductors. Unfortunately it seems I forgot
to bookmark the site. Can anyone help?

Thanks,

Larry, Have you tried looking at your history in your browser? It
probably remembers where you were. If you recognize the URL from the
list if you see it, just click on it and away you go.
If you are using Internet Explorer click on the little clock with the
green arrow on it to get to your history list.

Unfortunately I was having issues with IE so I ran Norton Clean Sweep
last weekend. It solved my problems with IE, but wiped out all the
info in the IE History folder.
Oh well...

Browsers usually only remember history of URL's directly typed in. If a
site is reached via a link the browser won't save the history of it.

What browser planet did you get that nugget from? Most browsers
(ever Exploder) remember every site you visit for as many days as
you set.

Perhaps this is it?

This may not be what you are looking for but it is a
clever way to make a Hartley oscillator using two
inductors without any coupling between them:

"Hartley oscillator requires no coupled inductors,"
by Jim McLucas, EDN Design Ideas, issue of
26 October 2006. The example is an 18 MHz
oscillator using dual-gate CMOS FETS but the
principle of transforming coupled inductors to
two individual inductors would be sound for any
active device.

It is available at Design Ideas Archive at
www.ednmag.com.

Thanks for the replies. This oscillator is cool, but not what I saw
before. I tried another Google search and can't find the one I saw.
Maybe disappeared out in cyberspace somewhere.
