It has been mentioned in chatter I've heard that some of the spooks sets
which are also so called earth resources sats that a problem with sat
receivers in Japan has made looking at that country at certain wavelengths
hard as these receivers are now so sensitive they pick up leakage through
the lnb to the dishes if the sat is in line with the broadcast sat.
I would have thought that a home dish was far too small even for a milliwatt
transmission to be seen in space myself, but what else could it be?



I understand there is also great concern that the gentleman's agreement that
authorities around the world will not use critical radio astronomy
frequencies may be out the window as frequencies are being squeezed for
mobile data use.

Even people like myself who used to enjoy listening to stations around the
world directly on a radio are now finding that switch mode psus, internet
over the mains cable devices and sundry unscreened heaps of junk being
churned out are making it almost impossible unless you embark on a field
trip to some place well away from civilisation!

Cool. I was always interested in amateur radio when I was young. But,
I was never able to get into amateur radio when I was younger due to the
very high cost. Instead, I got a Commodore 64 computer when I was about
15 years old. Turns out it was the "wave of the future". I never got
into the BBS scene, but later on I did use it in college to dial into
the university computer network where I could read Usenet News
(sci.space of course). Much more convenient than having to trek a
couple of miles to a "computer lab" where I could use a dumb terminal to
connect to the Unix mainframe. ;-)

Over the years, I spent a crap ton of money on that computer system.
Somewhere around $3500 by my estimation (using an Internet inflation
calculator). Today you can buy a smartphone, a really good laptop, and
a color printer for about 1/2 of that.

RF pollution is here and probably hear to stay.

You're absolutely right about that. And with LEO communications
networks looking like the next "hot thing", it will only get worse.
