Fast Radio Bursts and the Molonglo Radio Telescope (with video)
7,744 circular dipoles on 843 MHz feeding 176 preamplifiers and 88 IF amplifiers!
Read about how the Molonglo Radio Telescope has recently been used to study the mysterious Fast Radio Bursts:

There is a Grote Reber connection:

Grote Reber, Radio Astronomy, and Tasmania
Wow, the website of the National Radio Astronomy Observatory is a real treasure trove, with lots of ham radio info. Check out their page about ham radio's contribution to the exploration of the universe: http://www.nrao.edu/whatisra/hist_ham.shtml
The picture above shows antenna that Grote Reber built in his backyard in Wheaton, Illinois in 1937. It is now on display at the National Radio Astronomy Observatory at Green Bank, West Virginia. That's quite an antenna! Imagine the neighbors' reaction.
NRAO has a page devoted to Grote Reber:

I had wondered what had drawn him to Tasmania later in life. Here's the answer:
In the 1950s, Reber sought a field that seemed neglected by most other researchers and turned his attention to cosmic radio waves at very low frequencies (1-2 MHz, or wavelength 150-300 meters). Waves of these frequencies cannot penetrate the Earth's ionosphere except in certain parts of the Earth at times of low solar activity. One such place is Tasmania, where Reber lived for many years. He died in Tasmania on December 20, 2002.

RADIO PIONEER: GROTE REBER
Grote Reber has always been a hero of mine. Above you can see the dish that he built in his backyard to conduct radio astronomy in the 1930's.
