Morse
Type a message. Send it as sound, light or vibration — or build an ATAK data package to import. Everything happens on this device; nothing is uploaded.
Check the speaker before you blame the band.
If this device is playing through AirPods or any Bluetooth speaker,
nothing is entering the room at all and every rung will fail
identically. Switch output to a wired or built-in speaker first.
Point your receiver at the
speaker. Each band sends its own number, so whatever decodes
tells you which band got through. Tap a row when the receiver reports it.

Uses the camera torch if this device allows a web page to control it (Android Chrome). Otherwise the screen becomes the lamp — dimmer, but the camera receiver reads it fine at close range.
A standard ATAK mission package: the marker, the audio, the pulse
timings, and a copy of this app. Import it on a device, or open the
.wav anywhere.
Save this page and it keeps working with no network at all.
On a phone, use Share → Add to Home Screen and it behaves like an app.
To decode an incoming transmission on this device,
open the listener —
receive only, no transmitter.
