Software Defined Radio
The goal of this project is to get education and experience in the complex field of SDR technology and build applications for reception and transmission of various signals.
Předmětem řešení projektu je vytvoření nástrojů programového a elektronického
vybavení pro určení typu šifrované komunikace, její následné dekódování a vyvinutí nových
metod a nástrojů pro odhalování a vyšetřování případů kybernetické kriminality a ochrany
informačních systémů před kybernetickými hrozbami.

Equipment:
rtl-sdr sticks
bladeRF with USB3
Several computers to provide reasonable DSP power
Aim to build distributed receiving cluster. Currently radios in brmlab, on brmlab rooftop and at Jenda's rooftop are available.
Various antennas (HF, discone, 2m and 70cm Yagi, 2m and 70cm dipole)
Satellite card and dish
CB and PMR walkie-talkies
