Morse Code Between Two Phones: Does It Actually Work?

You need to get a message across a room with two phones and no network. Morse code over audio is the oldest trick in the book — and the most likely to actually work. This episode digs into what's really available on F-Droid, why the pretty translator app can't hear you back, and which decoder actually does the job. Then we get into the physics: why echoes, not background noise, are the thing that breaks indoor decoding, how Morse timing works at 5 versus 20 words per minute, and where the speaker and microphone hide on a phone you've never held before. We also cover the flashlight alternative — line-of-sight, immune to noise, useless around a corner — and the honest limits of what acoustic Morse can do when discretion matters.
