Feature request?

We just got the Wi-spi 2.4x and are using it to help us see rough signal strength of radios that are in the 2.4GHz bands, but on fixed frequencies.
Very cool.
What I was wondering is if there was a way to narrow the scanning frequencies, so that the scanning ignores frequencies outside of a specified range.
This way we could "focus" on a smaller block of th 2.4GHz spectrum and potentially it would even scan faster on that smaller window of frequencies.
Is this doable?

Currently it is not doable
however we are looking into this feature for future releases of Wi-Spy and Chanalyzer. 
That would be awesome.
Thanks...
Steve
I looked at the hardware interface specs and I found no commands to change the scanning behaviour of the Wi-spi 2.4x interface.
But I'm working on a program to process wsr files, one of its features is a band-pass and band-stop filter. This will not change the scanning, but you'll be able to filter a recording. This program is written in Python and is open source. It will be available on my site soon. If you want, I can send you a beta version.
I appreciate that, but it was mostly for the live-scanning. The way I will be using it, we'll be trying to do antenna tweaking, looking for changes in peak power in only part of the spectrum.
It just seems like we're wasting a lot of time scanning portions of the spectrum that aren't of interest.
Thanks for the offer of course!
Thanks for your suggestion, Steve. As Trent said, this is something we've been considering, and we'll keep you in mind for beta testing if/when we develop this feature.
