The designer(also the main engineer of DE1103 & Grundig SAT800) now ask
advise of the receiver function from BCLer, the DE1108 will be the
high-end receiver of DE 110X series, it comes with a large dot matrix
LCD display(128*64) two way speaker system, MP3 recorder, AM sync
detector, SSB, dual conversion, the reference basis is SAT700, it
should has better performance than sony 2001D, 7600G, SW77 even SAT700,
the outline dimensions will be large than SAT700,pls post your thougts
here, I will take the message to the design, thank you!

In additional to the other features, how about a couple of wide IF
bandwidths?

10 kHz for SW
20 kHz for AM and some digital modes

These bandwidths would allow users to take advantage of the full
bandwidth that may be broadcast (5 kHz on SW and 10 kHz on BCB). It also
facilitates bringing out the IF for DRM or other digital modes.

10 and 20 is too wide, a high quality 8KHZ filter is wide enough.
