Why are radio telescopes often built into natural depressions?
Radio telescopes are often built into sink holes or natural depressions in the landscape.* This is opposed to optical telescopes which are usually placed on mountains to avoid as much atmosphere as they can.
So why natural depressions? Is it easier…

How could the loss of the Arecibo Observatory have been prevented?
Would more preventative maintenance, more regular inspection of the cables have helped? Robotic/drone inspection systems? Could the right robotic system have done work to save it in the last few weeks had one been…

What might some examples be of radio telescope interferometric arrays made from "cheap components relying on massive computing power"?
This answer mentions that there are some interferometric radio telescope arrays
...consisting of very cheap components relying on massive computing power to retrieve the signals from noise...
The radio interferometers that normally come to mind…

Feasibility of radioastronomy in densely populated areas
In general, radioastronomy as well as optical astronomy depend on a good SNR. This meant to position telescopes as far as possible from noise sources. Optical telescopes were built at elevated points to reduce diffuse light from Rayleigh scattering.…

TPoint software, INDAT command - Format 4 (ALTAZ)
I am working (in fact, trying to work) with TPoint for improving a solar telescope pointing calibration (SST, in Casleo, AR) and stumbled on the input data for INDAT command. SST is a multibeam solar observation telescope with Alt-Az support.
INDAT…

how much further can a radio telescope than an optical telescope
I know that radio telescope can 'see'* further than an optical telescope but I would like to know how much further? (let's say the optical has a magnification of 50x and the radio has a dish of 90m in diameter).
*When I say see I mean how far into…
