#hamchallenge week 44 - Find and identify an unknown radio signal
Tune around the spectrum and find a signal you cannot immediately identify. Use a waterfall, a spectrum analyzer, online databases, or a SDR software to figure out what you're hearing. Where did you find the signal? What clues helped you identify it? What modulation or protocol did it use? Share a waterfall screenshot and explain your reasoning.
