Tickled me when I saw this… our TTN friend and veteran of these part Thomas Telkamp @telkamp strikes again! Guess we need to wait to hear from the man himself if the “short message” was in fact LoRaWAN or anywhere near compliant! 
Frequency used? So much for RED compliance! :shock:
“the signal was amplified to 350w using the 25-metre dish of the Dwingeloo Radio Observatory in the Netherlands”
It actually was a LoRaWAN message according to this other article : https://eandt.theiet.org/content/articles/2021/11/european-scientists-bounce-first-ever-lora-message-off-the-moon/ 
Indeed and it seems at ~433Mhz (if 350W I assume under special licence?!)… wonder what SF used… guess we will have to wait and book our tickets to

In order to find out more!!!
Na, just do it and then ask the police to investigate - LoRaWOT? Big radio? etc etc
imho if you are a licensed Radio Amateur you are allowed to transmit with 350W e.r.p. in the 70cm-band (abt. 433 MHz). This is an interesting version of EME (Earth Moon Earth) using LoRa as digital transmission.
But when I use my laser pointer to try to bounce off any of the reflectors left behind by the Apollo missions, nothing comes back - maybe it was all a big hoax. Maybe the moon is painted on the top of the dome we all live in.
It is flat and pilots never uses the elevator in level flight 
The moon is never directly over head in Bury UK so it doesnt reflect back down on you, but rather given
Some poor sole checking his/her/their LoRaWAN poacher tracking sensors down on the African savanna looks up at the moon and wonders why it has developed a little red spot?! The moon developing a pubescent pimple or start of measles or some guy in N.West UK shining a laser light that reflected towards him 
Here’s all the detail - including the sound of Chirps!
Properly trimmed sailplane doesn’t need any control inputs - how else would we drink our coffee & eat our sandwiches.
