This almost only happens with operators using Morse Code (CW) where the distinct signal can be heard and detected with sub-second intervals.
WebRadio signals take 8 minutes to travel from the Earth to the Sun, and from 5 to 20 minutes to travel from the Earth to Mars. The time varies because planets are constantly moving, and this affects their distances. If you’re interested in the history of radio waves, this video by NASA will help: Radio waves are a type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum, typically with frequencies of 300 gigahertz (GHz) and below. At 300 GHz, the corresponding wavelength is 1 mm (shorter than a grain of rice); at 30 Hz the corresponding wavelength is 10,000 kilometers (6,200 miles) (longer than the radius of the Earth).
