    I purchased this radio at Sharper Image some time ago. It's great for
    FM and shortwave reception, but AM (aka MW) reception is kinda' weird
    because of the 9 khz tuning steps which are used outside North
    America. Even if you key in the correct frequency, the radio rounds up/
    down to the next 9 khz step. I looked inside this thing expecting to
    find a DIP switch or something like that for getting the AM tuning
    steps to the normal 10 khz but I didn't see one. Any hints out there?

    It's imaginable that The Sharper Image may have some information about this.

    Do you have the manual? Sometimes there is information on how to change
    the stepping. It may often be a series of button pushes while powering
    up or something like that.

    I found it on Autralian eBay, so it may not be designed for the US:

    A Google search found these: (seems to imply
    only 9KHz.) (appears to be dead.) (if you do this through google,
    the Translate option gives you something as readable as the typical
    Chinese/English manual!)

    Check for a row of diodes connected to the key scan matrix, jumpers, or
    bridgeable/bridged solder pads.
