WLAN Expert had a "spectrum" display and a VSWR display but this only worked withy some cards. It worked with my DWL650 PCMCIA card but not my Entrasys Card. Netstumbles worked the other way around, with the Entrasys but not the 650.
They are the only 2 cards I have ever botheres to use for scanning/viewing the 2.4GHz band. Other cards I just used for networking.
