And you are right on the money. From what it looks like... It’s about the same but much slower and that would be a close description... Very slow wireless FAX. And X band is indeed a microwave frequency. lol

So, diving into the rabbit hole you opened, (I searched for which frequency Marconi transmitted) I have learned that Marconi’s radio transmissions from the late 19th century, essentially a spark trying to broadcast Morse code, have travelled beyond over a hundred stars!

I also learned of the work of Reginald Fessenden whose genius is seemingly unrecognized.

I also learned that Smart phones have half a dozen antennas in every unit. I’ve learned a lot this morning!
