If you are tuning in and want to perform Drive to the Edge, there are a few ways you can do so. It will last 15 minutes and start near the beginning of the 8 am hour on Friday Morning Menu on WEFT 90.1-FM.
If you have a car: you can tune in to 90.1-FM at 8 am and drive approximately along the edge of some of the red “local”and purple “distant” areas, safely examining what reception is like in those spaces. OR, alternatively you can safely drive in one of these areas, look for potentially obstructive visible features and examine whether it does or not.
If you do not have a car: try moving your radio around the house or your workplace, perhaps plugging it in to different outlets while still tuned in to WEFT. How does reception change depending on the location? (Also don’t get in trouble at work!)
In all cases, the notion is you and your radio move in some way, listening for the space where the signal is still clear but somewhat distorted, and consider how the visible landscape connects with the invisible radio signals.
