Looking at using SDR for radio astronomy its software that uses USB SDR dongles and outside antennas, had a dip into it some time ago, now have got things to work with windows I’m using one of these devices an RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio, along with various software programs like SDRSharp see below. the instructions for installing drivers under windows are in the quick start guide

This is an RTL SDR software defined radio receiver USB Dongle with RTL2832U ADC chip, R820T2 tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling. Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz (2.4 MHz stable) of ( HF works in direct sampling mode). Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, GQRX or SDR Touch on Android. Works on Windows, OSX, Linux, Android and The Raspberry Pi -Great for many applications including general radio scanning, air traffic control, public safety, ADS-B aircraft radar, marine AIS, ACARS, trunked radio, P25/MotoTRBO digital voice, POCSAG, weather balloons, APRS, NOAA APT/ Meteor M2 weather satellites, radio astronomy, DAB, or as a low cost panadapter with a ham radio.

Some musings.

The universe can be see as information. Order and disorder can apply to information. Everything in the universe is information.

How much information exists in the universe?
https://www.quora.com/How-much-data-is-there-in-the-universe

With the observable universe being 93 billion light years in diameter, the current calculation sits at a limit of 10^123 bits of information capable of being housed inside. Any more information than this and the universe would likely collapse in on itself.

The singularity and everything in it can be seen as information.Structuring information in images is a powerful way to enable people connect separate concepts together. If it was only its description in text then others might casually pass it by.

I don’t take any credit for any work here.

I collected some links and arranged them in a way that made sense to me
