Trace the callsign
Drifting on the wireless
Peeking on the narrowband
Looking up a callsign
Intel is classified
Call to empty spaces (return a value)
Ask for information (request denied)
Get through heavy systems (beyond the firewall)
Callsign is nowhere to be found
Don't give up, don't give in (dump the logs, trace the calls)
Don't give up, don't give in (trace the callsign)
Scanning all the channels
Looking for a sign of life
Searching for an answer
All that comes back is white noise
White noise has signals (testing)
Extrapolate the data (fast transform)
Re-read the algorithms
Go over permutations
Don't give up, don't give in (dump the logs, trace the calls)
Don't give up, don't give in (trace the callsign)
Trace the logs, trace the calls
Chase the callsign
