In 1820 Hans Christian Oersted noticed that electricity could cause magnets to move. This was the first "discovery" of radio waves.
Radio waves were discovered before the radio was invented.

Radio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory.
Three notable heavenly bodies discovered using radio waves include pulsars, quasars, and the cosmic microwave background radiation. Pulsars, which are rapidly rotating neutron stars emitting beams of radiation, were first identified in 1967 through radio signals. Quasars, incredibly bright and distant objects powered by supermassive black holes, were detected in the 1960s as strong radio sources. Additionally, the cosmic microwave background radiation, a remnant from the Big Bang, was discovered in 1965 using radio waves, providing crucial evidence for the Big Bang theory.
Guglielmo Marconi (Marchese Guglielmo Marconi), an Italian inventor, proved the feasibility of radio communication. He sent and received his first radio signal in Italy in 1895. By 1899, he flashed the first wireless signal across the English Channel, and two years later received the letter "S", telegraphed from England to Newfoundland. This was the first successful trans-Atlantic radiotelegraph. Wikipedia has a good article on this Nobel Prize winner, and a link is provided.
No. Radio waves were discovered around 1880. The first radio stations began about 1920..
The pulsing radio waves from the discovered object were detected using radio telescopes that can pick up and analyze radio signals emitted by celestial objects in space.

Grote Reber, not Grote Weber, is credited with building the first radio telescope in 1937. He used a parabolic antenna to observe radio waves from outer space, laying the foundation for modern radio astronomy.

Radio waves were first discovered by German physicist Heinrich Hertz in 1888 during experiments with oscillating electrical circuits. He demonstrated the existence of electromagnetic waves and their properties, laying the foundation for the development of wireless communication.
