Low-cost electronic devices have become popular in the research, educational and industrial sectors. This has permitted to avoid the acquisition of expensive specialized equipment. In electronics communications, low-cost devices can be seen in the Software Defined Radio (SDR). This technology permits having a communications system in a single device to work over different frequencies. Commercial examples are HackRf One and LimeSDR, they can be configured using GNU radio. However, this software does not allow the proper understanding of communication processes. Seeking to improve the understanding of communications, this work presents a software development to transmit digital signals considering an SDR. The proposal generates baseband signals, digital modulation schemes such as QPSK, ASK, FSK, and constellation maps. Also, it is possible to appreciate the Power Spectral Density (PSD), modulation of signals in real-time and modify the parameters of the transmission. This contribution can be considered in teaching and research, among others.
