How to catch the Ad-Hoc station beacon with an Orinoco card?

[Hiddink, Gerrit (Gerrit)]

Hi,

the Ad-Hoc mode is a mode in which no beacons are sent. It therefor
does not make sense to ask yourself what the beacon strength of other
ad-hoc nodes is. You could try to find out the signal strength of
data frames from nodes around you; I am not sufficiently familiar with
the wireless tools to know how to do this.

Regards, Gerrit
