Thanks yours, yes, thats the veiw I like to use as a general view as well, however I did find the calculated graphs on coverage quite handy when checking how far my wireless was / could be reaching.

How do you manage to avoid getting the AP mac addresses showing up on
the screen ?!
Thats the reason I didn't post that screenie as it shows all the mac addresses and I cannot figure out how to stop it doing that...

the radius function is there in KNSGEM as well, basically calculating the coverage from where the signal is received and what strength it is.

Have never used airodump with gpsd myself, so cant really comment on it,
BigD seems like the guy who would know all tho !
