They operate in bands and channels.  For more information visit the website below.

Dear Sir:\n\nWhile there have been some actual transmissions from Earth to the Solar System seeking echos, and some of this might still be going on in a coordinated fashion, as I understand it, the primary mission of the existing radio telescopes is to "Listen" to upper wavelength radio emissions from gas clouds, and other phenomina in the universe. Of course, once some interesting\nradio emissions are detected, a full spectrum scan of the target is most likely conducted to determine the full extent of radio\nsignals from that source.\n\nOther radio transmissions are made from Earth to our traveling Space Probes and Robotic Explorers at various locations in the Universe. A continual litany of telemetry, television and voice signals also flows between the Space Station and Ground Control Center to keep a constant watch on the health, status, and activities of the space crew, mission, and the station itself.\n\nI will defer to someone from one of those positions for an\nanswer as to the power and frequency of transmissions from Earth to the Space Station, Earth to the Robot Explorers, and Earth to the existing Space Probes way out in deep space.\nMy guess is that these various transmissions take place on frequencies between 2,500 Mhz and 40,000 Mhz. That is a \nvery large radio spectrum. \n\nSince my response turns around your question, in that I am telling you that the biggest radio telescopes listen rather than\ntransmit, let me also tell you that the biggest radio telescopes are not simply single structures at a given location. In recent years a scheme for the linkage of two or more radio telescopes was developed. Therefor, the biggest radio telescope would be an electronic combination of the signals from most of the largest installations on Earth. A lot of work has been done in that vein in recent years. Using more than one receiving antenna provides an easy means for researchers to filter out local ground (earthbound) noise generators and radio disturbances. Signals heard at the same time by widely separated receiving antennas (and equipment) are most probably from the sighted target source (assuming both antennas are aimed at the same target). It is also interesting to know that the radio signals that are received require a vast amount of processing to be identified and detected. The processing of the radio telescope incoming signals takes a huge array of computers and some very complex software programs to yield useable data.\n\nYes, radio waves do go on forever. However, their strength at the point of interception decreases by the square of the distance from the source. So, the strength of radio waves become very, very weak as you move into distances like 100,000,000 miles.\nThe wave front would continue out like rings of water in a pond until they hit something and bounced back off of it. In that sense,\na portion of the radio wave would not go on forever, but would become a new wave moving in the oposite direction from the new source (which was the object that the wave struck). The\nrest of the wave front would continue on until it struck something, and we repeated the above scenario. The exact same thing happens to signals transmitted from a sonar transducer in the water. Those devices are used to detect the depth of the bottom of rivers/oceans (depth finder), fish in the water (fish finder), or even other vessels (sub hunting). Sonar, uses sound waves and not radio waves, but the principle is almost the same.  Sound waves radiate out. Nearby echos are strong enough to be detected with existing equipment and are plotted and displayed on information screens. Some echos are so weak coming back that the existing equipment cannot detect/plot/or display  them.\n\nRegards,\nZah

60 times a second or 60 Hertz is correct.\n(In Canada it is 50 Hertz)

Not sure where you are, but you might want to check out "Free to Air" options....\nhttp://www.tech-faq.com/free-to-air-satellite.shtml\n\nThese receivers are available and easily programmable...\nhttp://dssftp.com/files/

I think the last person that answered misunderstood the question.  I believe you mean the XM and Sirius satellite radio.  The channels are the same no matter where you go, the same name and the same channel number.  It is different from FM/AM radio as there could be other stations use the same frequency but in another region.  Satellite radio is meant to broadcast all over the U.S. as FM/AM is not meant to.  \n\nIt is the same with television stations.  If you receive it on a cable system or over the air that channel is unique to that area but if you get Dish Network or DirecTv that station and number is the same no matter where you go in the U.S. and receive that signal.

call your local stations and see if they know\nthank you

An channel in communications will allow a certain range of frequencies to pass through it without attenuating (removing) it too much. In band pass communications this is a range of frequencies in the electromagnetic spectrum (eg. 400MHz-500MHz is a possible wireless frequency. In baseband communication the range is between 0 and a certain value and this is not normally suitable for wireless communications carriers.

It depends on the type of system.  You have point to point, which is direct communications betweent two radio stations.  You have repeater operation, which allows two or more radio stations to communicate with each other through a third system, which relays transmissions over a single frequency pair.\n\nYou have conventional repeaters, or trunked repeaters.  Conventional systems work as mentioned above.  Trunked systems utilize several frequencies, controlled by computer.  Frequency pairs are assigned on a first come basis, and are rotated among all the radios on a system.\n\nRadio is not transmitted through a satellite, unless it *is* satellite radio.  Radio systems operate via a ground antenna system.

There are literally thousands of satellites in orbit capable of both receiving and transmitting radio signals. Some of their names are Telstar, Comsat (Communication satellites), Cosmos 1602, GOES 7, Landsat 5, NOAA 12, Radarsat, and Seasat 1 (weather satellites).

This website should have the answer to your question:\n\nhttp://en.kingofsat.net/tp.php?tp=703

More info is needed. \n\nWhat is the pass band frequency, what is the spectral content of the input signal. Ideally how steep do you want it?
