You are fighting at least two problems: Noise and trying to get a
signal through a steel framed building. If you have a window office,
then try what I did with a 2010. Place the radio as close to the
window as possible to get away from pc and flourescent light noise.
Run a thin wire around the perimeter of the window, held in place with
suctioncup cupholders. Magnet wire works great and is virtually
invisible.

You should have similar results with a YB400PE or one of the Degen or
Kaito 1103 radios.
