It can transmit and it has a larger surface area (collecting area) than other telescopes. Didymos has been in the news recently... https://en.wikipedia.org/wiki/65803_Didymos#/media/File:Didymos-Arecibo-radar-images.png https://en.wikipedia.org/wiki/65803_Didymos#/media/File:Didy... Note the "Arecibo" in the file name. > Fourteen sequential Arecibo radar images of the near-Earth asteroid (65803) Didymos and its moonlet, taken on 23, 24 and 26 November 2003. NASA’s planetary radar capabilities enable scientists to resolve shape, concavities, and possible large boulders on the surfaces of these small worlds. Photometric lightcurve data indicated that Didymos is a binary system, and radar imagery distinctly shows the secondary body. That was done with radio pulses sent from Arecibo. Science will go on, but we've lost a tool. The area of the dish remains unmatched. https://space.stackexchange.com/questions/48666/arecibo-advantages-of-giant-dish https://space.stackexchange.com/questions/48666/arecibo-adva...
