What is the reasone for select Ku band frequency is 1411 G Hz in satellite communications?
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.

What are Larmor frequency?
The frequency or rate of precession of the nuclear magnetic moment (spins) and is proportional to the magnetic field strength.

The function of an oscillator in a radio transmitter is to?
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.
