Hello, We've discovered a new mode of attenuation we're calling Amazon Fade. It's clearly visible in this signal strength graph: Amazon Fade On Sept 28th, Amazon finished constructing a piece of steel member that is right in the middle of our signal between the Westin building and the Queen Anne site. The chunk of steel is towards the right of the building being constructed here, on the far side. Our Queen Anne site is directly behind it on the horizon. This webcam was setup specifically to monitor for the impact of this event, and I'm pleased to see the data come in. One other interesting this from this experiment is that the signal didn't fade at all as the floors were being built. Our signal shot clear in between them. It was only when that vertical riser was put in place that we measured an impact. I'll keep everyone updated on any future signal changes in our continuing study of Amazon Fade. :) --Bart
