I've been looking for some way to plot lightning strikes in real time on
a home machine. One that runs in Linux would be really nice so I don't
have to jump through hoops to make it work.

I finally found the Boltek LD-250 http://www.boltek.com/ld250.html which
when coupled with Stormforce software
http://sourceforge.net/projects/stormforce/ seems to do what I want. One
thing worries me, however. The LD-250's blurb says "The LD-250's
direction-finding antenna measures lightning strike direction while the
LD-250's receiver estimates distance from received signal strength". How
accurate is distance estimation from strength? I would think "not very".
