Better add a profanity filter quick. /s

That is quite fun! Not a lot of people know morse code so there is a lot of QRM (man made interference).
It is amazing how good the human brain is picking out signal from the noise.
I did spot one other Ham a fellow Brit (G4) but didn't complete a QSO (a contact). 73 (kind regards) de M5NCW

That might have been me! There were one or two M stations there. I heard a couple of stations calling CQ. Very difficult to pick out signals without any filtering.
73 de G4IYT :)

Damn I wish i knew morse code. I have no idea what this mean hahaha

Fun! Would be nice to have an automatic translator built in, or already the alphabet.
Btw, for emacs users, there is a `morse-region` and `unmorse-region` https://www.emacswiki.org/emacs/MorseCode to play with

Very cool. It does get a bit chaotic when there are a number of people keying. If there was the ability to add a narrow filter then it could be usable for a QSO (radio contact)!
There are some other apps designed for having QSOs - VBand[1] and Vail Repeater[2].
Finally if you want to learn to use morse code on the air check out Long Island CW Club[3]

Somewhat related, my iOS app[1] has a morse code reference and lets you train, it could be useful here.
Its backstory is also a bit silly, it started as the simplest app idea I could think of; I posted more about it recently[2].

This is good fun - any way of getting the alphabet on the screen for quick reference?

Not so much a communication tool but more like a realtime music collab one :)
Feels like a meeting on a remote island shore where nobody understands each other's language, but it's still hella fun :)

Pretty neat. It would be cool if it had an automatic decoder

Thats layer 0 let's build a TCP stack on it.

Very cool! I built something similar a long time ago: https://morse.halb.it and it blows my mind that it's actually being used by people

Really nice graphic design. If you build it out more, maybe you can teach users Morse code. Maybe a toggle button for decoding the dots and dashes.

That is super cool and fun. Well done. :)
My dad just bought a new printer. I joked and asked if it also had fax and a scanner. He said yes, not realizing I was making fun of him, so I asked if it also supported Morse code. That made it clear :) Anyway, I decided to take the joke too far and build a silly Morse code chat app for fun.
