I decided to head out and participate in the ham radio winex shakeout (facebook link) today using my lenovo and g90. Unfortunately the Lenovo is horrible for rfi, and blew out any chance of doing winlink. You can see a video of how bad it is here: https://www.youtube.com/watch?v=LGrLDo0JEO4 I tried a few different cables with and without ferrites on them, to no avail. 

This makes it completely unusable for ham radio digital modes, so I am looking for a solution. I have a pi and tried to use the hotspot on it to connect without it being hooked to the laptop (using a battery bank for the pi) but cannot get my laptop or phone to connect to it, so that was out as well. 

Does anyone know a cheap rfi clean laptop that can be used for these purposes? I'd greatly appreciate it. 

Cheers
