First low frequency search for alien technology in distant galaxies
https://www.sciencedaily.com/releases/2024/08/240826131354.htm
 Innovative study used the MWA's large field of view (FOV),
 allowing the team to cover about 2,800 galaxies in one observation
Source:
SETI Institute
Summary:
Researchers have announced a groundbreaking study using the Murchison Widefield Array (MWA) in Western Australia.
The research is the first to search for signs of alien technology in galaxies beyond our own,
focusing on low radio frequencies (100 MHz).
This new approach looks at distant galaxies,
making it one of the most detailed searches for super civilizations -- those more advanced than ours.

I can't even listen to shortwave much anymore because of all the EMI

Not only in town here, in house too:

and that is only a few of those in use...
OTOH over here, outside with a decent antenna, it is still OK.
Small village, some distance between the houses..

At higher frequencies we have radar interference..
rotating radar just a few km away from here.

Seems like one could make a PPI display, using a nearby airport radar
transmitter and your own receiver.

I was wondering if I used a variable delay and transmitted the pattern back if I could make them see invaders coming.
Bit of timing for direction...
I know it is evil...
But any enemy could create the illusion of invasions?
There are some knowledgeable radar people here, probably see a problem with this method?
A 10 dollar box a few km away all you need?
