it has nothing to do with kismet and everything to do with monitor mode, and drivers.

Netstumbler doesn't put the device in monitor mode - it's just querying the table of networks from the device, same as if you hit 'available networks' and wrote it down constantly.

Kismet puts the device in monitor mode - which changes how the radio is configured, what the radio measures, and how things are reported. Since a lot of drivers are hacked together w/out full internal info from the card, and a lot of card firmware just doesn't do a very good job w/ signal in monitor mode, and lot of the results are pretty much BS. They're definitely not strongly correlated with the numbers you get in non-monitor mode.

Kismet doesn't have a non-monitor-mode right now.

You could script iw / iwlist or wpa_cli scan / scan_results and logging.
