One advantage for KFBK on the FM Dial is that it comes in loud and clear with my wife at her work at an office in Stockton. KFBK on the AM Dial has lots of buzzing interference caused by the fluorescent lights
I listen online. No interference received, or radio required.
Of course, if you work in a business where there's no internet available (a warehouse for example), it's great to have FM available.
Even though the quality is not perfect, I prefer to listen via 92.5.
She is not allowed to use her computer for pleasure, just for business but they allow her to use a radio.
