How do I read the transceiver scheme?
When reading a transceiver scheme, you should first acknowledge that it has graphic symbols representing electronic and electrical components. What can be seen most often in the transceiver scheme are lines corresponding to real wires or traces of copper conductors on the printed circuit board. You can also view detailed links that show images of electronic and electrical parts and their equivalent schematic symbols that are connected to the perimeter phases. After learning about the stages of the district, you could get acquainted with different types of transceivers.
Transceiver consists of a transmitter and a receiver. The transceiver scheme can be drawn either on one page or on several pages. If they are applied to several pages, there will be a connection to other pages on the edges of the scheme. For example, "+VCC" is a voltage with a normal positive current (DC). The negative side of the power supply is usually marked with a small threemel with one tip pointing down. Very simple transmitters have oneabout a crystalline phase that works at one frequency. Multiple-frequency transmitters usually use one reference crystal with an integrated circuit that usually synthesizes different frequencies for a multi-channel transmitter. The transmitter must have a relatively accurate crystal to ensure that remote receivers find the carriers that send.
Schematic symbols are accompanied by one letter or one identifier followed by a number. The resistor can be marked as "R1", transistor as "Q1", an integrated circuit as "IC1" or "U1" and a capacitor as "C1". The transceiver scheme also has shortcuts, such as Power Suprint (PSU), local oscillator (LO), receiver (RCVR), transmission (TX), crystal (XTal) and many others.
You will have many options when buying a transceiver. Standard transceivers can be placed on a table like a basic transmitter while the pocket transmitter is portable transceiveRy. Creating a transceiver can be an interesting hobby. In the first days of the radio, hosts and enthusiasts had fun building electronics and cabling for antenna system. Usually, the larger the antenna, the further the signal range.
When using a transceiver, you need to know the required frequency of the receiver and be able to set it on the transceiver. Digital controls allow the frequency preference. In this way, you can choose the right frequency that you can listen to or watch.
