    Just to be sure, do you have a gps plugged in, did you start gpsd and wait 60 seconds before starting airodump?
    Still not underestimating the power...

    There is no such thing as bad information - There is truth in the data, so you sift it all, even the crap stuff.

    yes, i have to wait that BT gps see the satellite, i test if it work with xgps
    after this airodump show on video the correct gps data , and write it on .kismet.nextxml file.
    but .cap give the error

    What happens if you try it with kismet, you can channel lock to your AP without issue and it saves .cap files as well. If one is working and the other isn't, that helps narrow down the problem.
