Well this is interesting. Turns out the first few microseconds have a key used to decode the time and message of the FRB

One message repeated there was no variance in tone or signal. From what I gather (Inside Sources) the message has lots of mathematical data but starts off with "We are here" and "We will meet soon". I wonder if the message instructions are a portal or other device so they don't have to travel the massive distances?
