necromancy
That would be me.
But it is a good discussion on several points.
SOS was a fairly new signal at the time of the Titanic Disaster.
CQD was standard from the start of wireless.
Also, They did not transmit in what most presume by todays standards.
It was an almost scratchy blur type transmission.
Do a Google for Titanic's messages and you hear this.
For the AC-4, I did a sound track that HAS a message.
I thought about useing the transmission sounds of the period, but.
As most of the AC-4 is going WAY above everyones heads?
I'm glad I used WWII standars for the sound loop.
Now!!
Decode the message!!!
