1) Cyber Security must become an intergral part of the overall system design process.
2) Some of the people I help with this work make Cyber Security the last step - more often than not, an afterthought.
Your thoughts?

But it's also something of a #retro design, given plans for constellations consisting of lots of relatively cheap, low-altitude #satellites https://www.cnet.com/home/internet/hughes-bus-sized-satellite-promises-better-broadband-in-the-boonies

If free space path loss increases with frequency, why is it we can still see light from distant galaxies, etc.

20 followers · 252 posts · Server mastodon.sdf.orgReally interesting writeup on what sort of equipment it take to pump out 330,000 W of FM radio. (There is also a video tour linked)
https://www.jeffgeerling.com/blog/2022/1-million-watts-rf-how-fm-supertower-works
TLDR: one transmitter is 16 RF modules powered by 40 independent power supplys, that outputs 30kw of RF through a 3" copper coax tube, and there are 10 of these feeding the antenna.
