Martha Is Dead has a side quest called Number 6934 (unmissable, story-related) which spans over different chapters of the game. During this quest, you need to interact with a telegraph machine several times to compose and send morse code messages. This is required to complete Lapo’s quest and obtain the trophy 
The Lovers. Below is a list of all Morse Code Message Solutions and when they are needed.
Chapter 8 – The Burial
After cutting the telephone pole’s wire, interact with the telegraph machine at the barns. Here are the correct messages:
- Town (third column),
- On Fire (second column),
- Tank (first column),
- Road (third column),
- Near (third column),
- House (first column)
- Over (second column)
- Received need defensive line map leave near building beside river over and out
Chapter 11 – The Graveyard
After sliding the photo under the house, interact with the telegraph machine at the barns. Here are the correct messages:
- Town (third column)
- On Fire (second column)
- Photo (second column)
- Map (third column)
- Positioned (third column)
- Over (second column)
- Tank located over
- Received over
- Find weapons cache near woods over
- Received over
- Place flag pole light close communications over and out
These are all the Morse Code Message Solutions for the side quest Number 6934 in Martha Is Dead.
Correction with this one – the entire thing can be done in chapter 8. No need to wait until chapter 11 to do the 2nd half (I did the entire thing in chapter 8, up until getting the trophy). Alternatively (though I haven’t tested this way), it may also be possible to do the entire thing in chapter 11.
Thanks! I don’t understand a thing
Why not to make a letter and a code near it
I can’t understand this morse labyrinth
lmaooo the morse labyrinth. i couldn’t understand how to decode any of the messages. thankfully someone figured it out
