The RF Scanner resides in the MSR and its antenna is located on the LVEA roof, close to the GPS receivers. It scans for RF signals in the MHz range, producing a time-freq png plot every 10 minutes.

The freq plots are now available via the DTS web server, URL is  https://badger.ligo-wa.caltech.edu/rfscan/pngs/ (one directory per UTC day).

I converted the 144 daily plots into a mp4 movie for the days May 01-08, for example  03 May MP4 Movie. Note that there are some 700-800MHz bursts in the second half, which represents LHO business hours on site (5am - 5pm PDT Friday 3rd May).
