I just finished adding a note in the spectrum analyzer part of my web
page. This shows a photo and output response plot for a 9th order 80
MHz low pass filter using SMT components. This is an improved circuit
over the one that we had in the original 1998 QST article design. A
low pass filter is a circuit that really benefits from surface mount
technology, but you have to look out for inductor Q.
Just go to the site at

to the SA entry. I put a "green arrow" on it to mark recent changes.
