The XHDATA D-109 is terrific radio, but there appear to be some flaws. Some users have experienced overloading when using external antennas. This video shows many many spurious signals between 1700 kHz and 2450 kHz. These could be strong SW signals or MW signals bleeding through.

I have two versions of this radio, the first release, which had a SW input issue between 17000 kHz and 19999 kHz, and the updated version where this flaw has been fixed. I tested the spurious signal issue on both versions, and they both receive exactly the same signals. Seems like it could be a firmware issue. This flaw, however, does not detract from the overall functionality of this radio, it remains a great radio at a good price!
