From Yashwant Gupta, "Phased Arrays":
"For identical elements, this phased array gives a sensitivity which is n times the sensitivity of a single element, for point source observations. The beam of such a phased array is much narrower than that of the individual elements, as it is the process of adding the voltage signals with different phases from the different elements that produces the narrow beam of the array pattern."

In 1905, Karl Ferdinand Braun showed how an array of antennas can adjust their phases to aim a radio broadcast, also used today for advanced radar systems. #Poetry #Science #History #Electromagnetism #PhasedArray #Braun (https://sharpgiving.com/thebookofscience/items/p1905b.html)

A _phased aray_ is a line (or grid) of antennas where we can tune the phase of each antenna, to use interference to change the direction where most of the signal energy goes!
In his beautiful video, Nils Berglund has staggered the frequencies of his 19 antennas to achieve a nice sweeping effect!
It's nice to see the same sweep twice, but don't you also wonder how it might look like if the video would run a little further? Nils has been developing his inspections of phase arrays in a dramatic fashion for a while now, and this is just the most recent in an on-going series of videos.

@winstonsmith This sounds really fun and cool. I've wanted to mess with #phasedarray but like...from scratch. I.e. not as a way of doing #ham, but just to figure out how.
That said, I don't think this rules out a hardware issue. If anything "our receiver is really complicated, it must not have any problems" seems...not very convincing.
The "different receivers see the same thing" is a lot more compelling.
