class C
A type of superheterodyne radio using two separate mixers, each producing its own intermediate frequency. The block diagram of such a receiver is like this: RF -> M1 -> IF1 -> M2 -> IF2 -> D -> AF
RF = Radio Frequency
It's a junction gate field effect transistor that has it's bandwidth tuned to operate (amplify) in the radio frequency range.
Radio Frequency is a wireless technology consisting of a transmitter and receiver tuned to the same frequency
depends on frequency and power

I'm assuming you are talking about GPS when you say "satellite." RF tracking can be directional. It takes three RF receiver stations to triangulate the position of an RF transmitter and is usually less accurate than GPS. RF is also more limited by range, so the RF tracking stations are usually required to be mobile depending on the strength of the transmission signal.
class C
Use a scanner or other portable VHF receiver, with an external directional antenna such as a loop or Yagi.
A receiver test set is a device used to measure and evaluate the performance of a communication receiver. It can generate test signals and measure key parameters such as sensitivity, selectivity, and dynamic range of the receiver to ensure it meets specified requirements and standards. This tool is commonly used in the manufacturing and maintenance of communication equipment.
RF- Radio Frequency, which is in the measure of kilo & mega Hz range
RF means radio frequency or relativity low range of frequency microwaves however are into the top range of the spectrum or very hi frequency.
The human eye can perceive about 20 stops of dynamic range.
we can create transmitter by using modulator circuit depending what frequency range you would like to use if you want to use FM range 88 to 108 MHz than you may refer to FM modulators and if you are going to more than 300MHz than you will need RF receiver.
RF Loop Back ,Usually used in all RF Transceivers to covert the Transmitted signal into the Receiver frequency ,checking the Overall performance of the Terminal .This is an Option useful only in maintenance and not recommended BY Standard Authorities (Fcc, ETSI, etc )
The Yongnuo 560 IV flash features a guide number of 58, manual power control from 1/1 to 1/128, built-in wireless receiver, and a zoom range of 24-105mm. It also has a recycle time of about 3 seconds and can be triggered by a Yongnuo RF-603 or RF-602 transmitter.
