Is THAT what you're doing to scan ?

It looks like what you were doing was scan a tuned frequency for pids. 
If you want to do THAT, then you must actually be tuned to the given
frequency.  you need to azap SOME_CHANNEL -r, and keep that running
before attempting to run 'scan -c' ...  I think you should try the scan
command that I mentioned above.
