There is time delay because the radiotransmissionsare not instant; they may travel at the speed of light but that is notinstantaneous. Also, the radio waves have to travel up to asatellite, as the waves cannot go through the Earth.
Earth would appear as a bright source of radio waves to extraterrestrial astronomers due to human-made radio transmissions. These transmissions, including radio broadcasts, satellite communications, and radar signals, create a radio "glow" around Earth that can be detected from great distances in space.
In radio communications, the letter "E" stands for "Echo." It is used to represent the phonetic E in order to ensure clarity and accuracy during transmissions.
It hasn't been done and there is a problem because the background noise would prevent the use of radio communication over more than about 1 light year's distance. Radio waves travel at the speed of light, so it would take 2 years to get a message there and back from 1 light-year away.
The ionosphere helps radio signals to be reflected and refracted back to the Earth, allowing long-distance communication via the ionospheric skip. Different layers of the ionosphere interact with radio frequencies in different ways, influencing communication quality and range. Variations in ionospheric conditions can impact signal propagation by affecting signal strength, delay, and interference.
A transceiver is a device that can both transmit and receive a radio signal. It combines both functions in a single unit, allowing for two-way communication over radio frequencies. Transceivers are commonly used in applications such as two-way radios, walkie-talkies, and wireless communication systems.
A radio that receives Frequency Modulated (FM) transmissions.

Radio-radial delay is the delay between the two radial pulses (this is observed when checking both pulses simultaneously).
Amplitute Modulation signals. a modulation(mixing)method used in early radio transmissions.in many countries, radio transmissions below 30 Mhz,are still using this method.short wave,medium wave transmissions,and some extent of VHF transmissions are possible in this method.

Yes, they can monitor and decipher.

CONTACT! Example (US radio transmission): "Lima 6 this is Mike 6 we have contact over!" Further transmissions would follow...normally with audible gunfire in the background of the radio transmissions.
radio transmissions and observatory purposes
DMG Radio Australia was created in 1996.
Car radios are for receiving music and entertainment programs. Most aircraft will not have this type of radio. They will only have a 2 way transmitting and receiving radio for communicating with airports and other aircraft.
