FSK modem with AX.25 protocol
 Vojtek, Michal ; Šebesta, Jan (referee) ; Fuchs, Michal (advisor)
The purpose of this thesis is to design FSK modem for Packet communication. In accordance with accessible literature was constructed functioning circuit schema and subsequently there was constructed a motherboard which is mainly assembled from SMD technology. It makes this modem mobile and very easy usable in terrain. Modem communicates with PC via USB bus. Also this bus is used as power source for this device. Communication between modem and PC is realized by KISS protocol and connection with tranciever is realized by AX.25 protocol.

Design and Implementation of AX.25 Monitor
 Demín, Martin ; Drábek, Vladimír (referee) ; Škarvada, Jaroslav (advisor)
The work describes a design of an implementation of an AX.25 Monitor, capable of demodulation and decoding of AFSK 1200/2200 modulated AX.25 frames. The output is provided to USB/UART port and to the LCD. Demodulator uses FIR filters implemented in MSP430.
