Monitoring the Spectrum: Building Your Own Distributed RF Scanner Array

Monitoring the Spectrum: Building Your Own Distributed RF Scanner Array Software-Defined Radio (SDR) has increased in popularity in recent years due to the decrease in hardware costs and increase in processing power. One example of such a class of devices is the RTL-SDR USB dongles based on the Realtek RTL2832U demodulator. This talk will discuss … Read more

Fault in Digital Radio Reception — Searching for the last true analog radio – Panasonic & 5 Core

Shortwave Radio: Shortwave radio broadcasts, … Read more

A Nonlinear History of Radio

This highly nonlinear history of radio touches briefly on just some of the main stories, and provides pointers to the literature for those who want to probe further. Integrated circuit engineers have the luxury of taking for granted that the incremental cost of a transistor is essentially zero, and this has led to the high-device-count … Read more

Economy of the Ether: Early Radio History and the Commodification of Music

The early history of radio is an absorbing and complex saga. Often told from the narrative perspective of its inventors, technical milestones, or regulatory developments, little has been written about the commercial history of early radio and its influence on the commodification of music. Using a theoretical framework of commodification based upon the concepts of … Read more
