The amateur radio club at NASA Johnson Space Center in Houston retransmits audio on 146.640 MHz , and the club at NASA Goddard Space Flight Center in Greenbelt, Md., retransmits audio on frequency 147.450 MHz. The signals can be received for about 25 miles.
Read moreWhat frequency does NASA use to communicate with Mars?
Most often, Mars 2020 uses its ultra-high frequency (UHF) antenna (about 400 megahertz ) to communicate with Earth through NASA’s orbiters around Mars.
Read moreShould I turn X band off?
X band is the oldest type of police radar frequency, but it is not used as frequently today as it used to be. Even though some people prefer to turn off the X band detection on their radar detectors, it is wise to leave it on as some older radar guns still operate on the X band.
Read moreWhat does X Alert mean on a radar detector?
X band radar is defined as radar waves that fall between 8.0ghz and 12ghz , but law enforcement X band radar guns operate universally on 10.5ghz. This is the oldest type of licensed police radar frequency, and is not widely used anymore.

Read moreWhat is the frequency band for the satellite communication and radar?
Use in satellite communication Nearly all C-band communication satellites use the band of frequencies from 3.7 to 4.2 GHz for their downlinks, and the band of frequencies from 5.925 to 6.425 GHz for their uplinks .
Read moreWhich frequency band Cannot be used in satellite communication?
Which of the following bands cannot be used for satellite communication? Explanation: MF is a lower frequency band than Ku, C and X bands and does not lie in the microwave spectrum. Microwaves are used for satellite communication since the lower bands get reflected by the ionosphere. 8.
