Dear devs.
Ham radio operator here and DayZ player.
The little paper in-game showing the chart for the International Morse Code alphabet en pro-signs contains errors.
The M and the pro sign COMMA is wrong in the chart.
The M is showed as: - The same as the letter T , which should be --
The Comma is showed as: -..- which should be --..--
Hopefully this is only reflects the paper chart in-game and not the morse sound system in-game when Badlands is launched.
Beware that some websites if search on Duckduckgo or Google show the same error. Please lookup a trustworthy site like the ARRL or even Wikipedia.
