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:
http://www.dpmega.com.hk/usermanual/...UserManual.pdf (seems to imply
only 9KHz.)
http://www.tutorials-xe.com/REPAIR/Kchibo-mods/ (appears to be dead.)

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.
