No, but I just ordered one. $103 total including shipping via Paypal.
Claims will ship on Dec 22 (yesterday) which is a bit optimistic.
We shall (soon) see.

Looks kinda interesting, 96ms sweep time is good, but they don't say
anything about sensitivity, which is pretty important. I've already
got a Proxim 7400-based "spectrum analyzer", which is nearly deaf and
unusably slow....

The ability to download actual recordings seems as if it could be
useful, especially if it is continually being added to.

Let us know how it is! I almost ordered one myself, but I'll let Jeff
do the honors.

Yeah, I have the same problem.

Try the AVI files to see how it should look.

Looks much better than the Proxim 7400 cards. If the calibration on
the vertical sensitivity is accurate, it should be fairly sensitive.
However, don't expect the same range as with a 802.11b/g connection.
Without SS code synchronization, the de-correlation loss and the loss
of the 10dB processing gain will drastically reduce sensitivity. The
lack of an external antenna connector might be a problem. My
guess(tm) is that this is really a USB dongle with frequency hopping
firmware and software. That divides the band into 80-90 channels,
each 1MHz wide (same as the Proxim 7400 FHSS card).

Did you look at those CSV file contents? All the values on the 3ea
Wi-Fi recordings, at any frequency and at any time, are all around
-61dBm. Methinks they've goofed somewhere. Those files are useless.
The GE Microwave CSV file looks reasonable.

Yeah, it looks pretty good. I dropped them a line to find out if they
had any sensitivity numbers, and got back:

/*
I have attached the datasheet, which should have the sensitivity
information you are looking for.
*/

The included document, however, is the same one found on their
WWWebsite, and while I agree that it _should_ include the information
I'm looking for, it clearly doesn't.

Another little tidbit:

/*
Wi-Spy sweeps the 2.4 GHz ISM Band about 10 times/sec, and samples
every 1 MHz.
*/

Let us know! The Proxim card sounds really neat, too, until you
realize how slow and deaf it is. At least this one is faster! 8*)
