Art,

Funny that you should ask, because the October 2008 QST (just arrived a few
days ago) has a computer-based DIY spectrum analyzer project. Doesn't look
too difficult: a couple of dozen parts and a software program that's
downloadable from the ARRL web site.

S A s are usefull for antenna hobbyists. Some twenty years ago there
was a DIY S A that used a t v tuner in
Ham Radio. Moving forwards some twenty years and most hams have
computors and there are 2.4 Ghz
spectrum analysers out there as well as audio set ups for computors.
So what is available today for hams
in the HF BANDS? There are a lot of older type audio S A s on E bay
but I haven't heard of anybody modifying thoseand with most having
computors it would seem reasonable to think that there were components
available that could performn between audi and 2.4 Ghz. So has anybody
seen any modern type DIY spectrum analysers
around for sale or kits? I have 141t and other types of SA which now
are considered bulky and I would really like something smaller or say
modify something like a audio setup as a project.
