Spectrum protection for radio astronomy: details, successes, failures, challenges and convergence

This talk will give an overview of the mechanisms that have evolved to provide statutory protection for radio astronomy observing, stopping along the way to note some cm-wave successes (the 21cm H I line and recent agreement not to point 9.6 GHz high-power orbiting radars at radio telescopes), defeats (the 1612 and 1720 MHz OH lines), and challenges (the near-term viablility of 68 - 90 GHz mm-wave spectrum). I’ll discuss why ground-based radio and OIR astronomy historically went their separate ways and why there is increasing motivation for convergence of spectrum protection across the various wavebands.
