Thankyou Ted - That's very interesting that they will be doing that - October 4th 2022, the article reads that the message will be sent. The article says it will be 39approx years before it reaches the Trappist-1 System, and no less than 80 years before we can expect a reply. (Unless of course its intercepted along the way).
I am wary of this form and attempts of contact. Stephen Hawkings words of warning ring in my ears.
The Beacon in the Galaxy (BITG) message contains Earths location, DNA - so much detailed information being prepared to be shot into the Trappist-1 System.
