Shorter wavelength, higher frequency.
No. The squelch circuit is used to mute the background noise when no signal is received. You could try to catch weak signals by disabling the squelch.
The working distance depends a lot on the receiver that's being used to pick it up.The Pioneer-11 spacecraft was launched in 1973. The last radio contact with itoccurred in 1995, when it was 4 billion milesfrom Earth. Communication mighthave laster longer, but its on-board power source ran out of gas at that point.The spacecraft transmitted just a few watts of radio power, at microwavefrequencies. But the antennas that were used to receive its signals are disheshundreds of feet across, with supercooled electronics.
Radio signals travel at the speed of light, which is approximately 299,792 kilometers per second (about 186,282 miles per second). Triton, Neptune's largest moon, is about 4.3 billion kilometers (2.7 billion miles) from Earth on average. Therefore, it takes radio signals roughly 4.3 hours to reach Triton from Earth, depending on the relative positions of the two bodies in their orbits.

The receiving antenna in radio communication serves to capture electromagnetic waves transmitted through the air. It converts these radio frequency signals into electrical signals, which can then be processed and decoded by a receiver. The efficiency and design of the receiving antenna play a crucial role in determining the quality and strength of the received signal, impacting overall communication clarity and reliability.

Speed on spacecraft is typically measured using instruments that track the craft's velocity relative to its starting point or to another reference point in space. This can be calculated using onboard sensors, such as accelerometers or radar systems, that measure the spacecraft's distance traveled over time. Speed can also be determined by tracking the Doppler shift in radio signals between the spacecraft and ground stations.
Analog signals can be received using an analog receiver.
Scientists communicate with spacecraft in space using radio waves. Ground stations on Earth send commands to the spacecraft and receive data from it through radio signals. These signals travel through the vacuum of space to maintain communication with spacecraft regardless of their location in the solar system.
Mercury communicates with Earth primarily through electromagnetic signals such as radio waves. NASA's spacecraft and missions to Mercury, such as the MESSENGER and BepiColombo missions, send data and images back to Earth using radio communication systems. These signals are transmitted over vast distances and received by antennas on Earth to decode the information sent by the spacecraft.

radio magnetic waves that are received in the air
Information is sent between Earth and spacecraft via radio waves. The spacecraft transmits data to Earth using its communication systems, which typically include high-gain antennas. Ground-based tracking stations receive the signals and send commands back to the spacecraft. This communication allows for the transfer of images, scientific data, and instructions between Earth and the spacecraft.

(Intermittent - stopping and starting at intervals) During the summer, there are intermittent dust storms in the desert. NASA received only intermittent signals from the damaged spacecraft. We made only intermittent progress on the project.
