Homebrew 2.4 GHz spectrum analyzer using Proxim HomeRF nics

Greetings:

Does anyone have any experience with the 'Airsleuth' or 'Wifisleuth'
product which uses Proxim Symphony HomeRF adapters to do basic
spectrum analysis in the 2.4 GHz ISM band? The technique involves
monitoring RSSI (or perhaps AGC?) during sequential scanning of
the 79 FHSS channels (each 1 Mhz apart). This also seems to limit
coverage to 802.11b/g channels 1 through 11 (omitting 12-14 at the
top end).

I seem to remember some references to other projects using these
adapters, but I cannot find anything on the Web. One would hope
for an open source effort.

Proxim has in the past been quite unwilling to release
details of their adapters to driver writers, even with willingness
to enter an NDA. How do you suppose the developers of the
Airsleuth line got the poop? R.E.?

If you have this product, I would appreciate a discussion with
you.

Regards,

Michael
