FM Transmitter of APRS Telemetry in 144 MHz Band
Bohátka, Jan ; Šádek, Václav (referee) ; Urbanec, Tomáš (advisor)
APRS system is described are sent toin my essay, which is used for sending and receiving text messages. The text messages frequenc 144 MHz by using the modulation scheme AFSK. APRS communicate by using the protocol AX 25, which sends and receives the text messages in the area where are carried despatches and control bits as well. The whole area of high frequency part is in one integrated circuit. The control, coding and decoding of the area is the microcontroller’s job.
