This looks like a nice little analyzer. I have used the AD8302 and it
does a decent job within its 60 dB range

Nice to have sound card analyzers with software and all, but a real rf
analyzer in a small, functional package would be so

TAPR has a nice VNA project going, www.tapr.org... it was featured in a
July/August QEX. They are also going to offer it assembled I think thru
Ten-Tec. It does a lot more than an antenna analyzer to boot, but
requires a computer so is not portable. It does all the complex

May I suggest that people consider the N2PK Vector Network Analyzer.

So far, I think it is a better design and is cheaper.

didn't mention it because the project is currently closed unless you are
willing to take one of a handful of left over boards, which require
installation of some mighty small SMD parts. The original project had
those parts

This looks like a nice little analyzer. I have used the AD8302 and it
does a decent job within its 60 dB range limitation, which should be
enough for most measurements. Since it has its own oscillator, I assume
the levels are permanently set to maximize dynamic range. Note that it
is a one
Thanks Stewart, I missed that... the website was exceedingly slow here
and I got tired of waiting for the manual to download. That makes it
definitely worth a look, especially at that price. I love the N2PK, but
it's a bit slow and needs better software... but for detailed
measurements it's

Here is a nice one if you are looking for a kit.

One of the problems with designing and selling kits is the production
volume. Will enough of the kits be sold to justify the cost of developing
the product. I don't know if there is enough demand in amateur radio to
justify the development cost of a spectrum analyzer.
Let me state the
Shouldn't be too hard to even have it use a PC as a display, much like the
sound card analyzers and PC-based oscilloscopes do, and that should help keep
costs down.
Count me in!

Hi Wayne,
That's sounds very interesting.
What frequency range and resolution would you like to have in the spectrum
analyzer?
What dynamic range is required for it to be useful?
Other specification?

There are a couple sources for boards for the W7ZOI spectrum analyzer
project that ran in QST some years back. Also, for about $500-700 on
eBay you can get a used HP or Tek SA that will blow the doors off an
inexpensive kit version. If you do a lot of RF design work, it's a must.
