RPITX - a transmitter along frequencies from 130kHz to 500MHz

Great news. Raspberry Pi can now emit RF signals along a much wider range than previously publicized. It is three years since a team at Robotics Imperial College London wrote PiFM, a FM transmitter based on C and Python for the Raspberry Pi. PiFM enabled even novice Raspberians to setup a fm transmitter. RPITX by Evariste Okcestbon sets a new standard and may see a wide range of applications compared to PiFM. By design it is both more versatile and closer to the needs of a radio amateur . It is able to transmit at lower frequencies than even the HackRF , as it includes frequencies between 130kHz and 1MHz, though it is not capable of transmitting above 500MHz at this point. Innovations in electronics are still possible on Raspberry Pi, a modest platform for the auteur with the modest budget and a deep understanding of a well-documented interface and architecture. RPITX is available from GitHub . A third argument in the fcntl function open lacked in several source files (9th novem
