Ku band, (Transmit frequency 13.75 to 14.50 GHz, Receive frequency 10.70 to 12.75 GHz dependant on which region of the earth you live in) is used rather than C band (4 to 6 GHz) because the higher frequency allows for broader transmit and receive bandwidths, so more data, computer traffic, movies, etc can be sent. The signal power lost in transmitting from earth to the satellite and back to earth again varies with frequency, but not as a simple linear sloping line increasing with frequency way, it has peaks and troughs. This is because at some frequencies Oxygen and Water absorb much more power and it is difficult to generate enough power to pass a strong signal through the atmosphere, so those frequencies are avoided. Ku band uses a part of the frequency spectrum with a lower atmospheric loss between earth and space, so relatively less microwave power is needed to efficiently transmit to and from the satellite.
The frequency or rate of precession of the nuclear magnetic moment (spins) and is proportional to the magnetic field strength. Radio waves of the Larmor frequency are used to produce RF pulses. here is the link where I got this information. www.elp.manchester.ac.uk/pub_projects/2000/mmmr7gjw/glossary.htm then select the L letter
There are typically at least two oscillators involved in the transmission aspect of a radio transceiver: one is the transmission oscillator which creates a cosine waveform modified with the input key (the information being broadcasted), the other is the variable frequency oscillator which allows one to select the desired frequency for communication. On most transceivers the VFO also modifies the receiving end of the device simultaneously.

You click the stage icon next to the list of sprites. The same way you would select a sprite.

For past years earth-based satellite imagery in Google Earth you can select 'Historical Imagery' under View menu. This shows a timeline slider from which to select available satellite and aerial imagery from the past. NASA also provides vast archives of satellite imagery much of which are available online such as the NASA Image Gallery

Open a web browser such as Firefox and go to http://www.sat-direction.com/. Enter your address or location, and select the desired satellite. It will draw the direction of the satellite on google maps.
If you access the menu on the DISH Network satellite receiver and access the point DISH screen, it will then allow you to enter your zip code & select the satellite you are currently pointed at. After entering your zip code & selecting the satellite it will calculate the azimuth and elevation angles for you.
In Canada the following companies offer exceptional satellite television service, Bell Satellite, Star Choice and Shaw Direct. Those companies offer satellite services in select areas. You must contact them to see if they offer their services in your area.

Select TV is a low cost type of satellite television available in Australia. It is also a company that provides IPTV in Malaysia. The two companies do not like to be mixed up.
In Device Manager, right-click the serial port labled Communications Port (COM1), and select Properties. Select Port Settings tab.
To program a conventional frequency into the scanner first select a channel to program and then enter the frequency you wish to store in that channel number and finally press E. According to the manual this scanner is capable of receiving trunked communications. Due to the complexity and length of this process the link below in the Related Links section goes to the manual in PDF format that describes the process. The Programming Trunked Systems chapter begins on page 40.
