Bill, this sounds fascinating....sounds similar to what I'm doing, but 
looks like a true spectrum analysis rather than monitoring point 
frequencies.  I've only just skimmed the site, but is there an explanation 
of how the monitoring is done, or is it proprietary?   Is the same receiver 
used at all sites?

best wishes,

Nick
