This is an overview of my experiments with low power, low bandwidth radio transmissions commonly called QRSS transmissions. The term QRSS is a derivative of QRS Q-code meaning Send Slowly (or shall I Send Slowly, if followed by a ?). It is a transmission mode made possible by DSP techniques that can extract very weak signals from noisy channels.
