If you live in a city area or some rural area with a real strong AM

understand that this station is not a real longwave radio station.
Its a image from the broadcast station when the station is strong
enough to bleed on other longwave frequencies. * The radios that I
have is the DX-380, DX-390, DX-392 and the yes the new Grundig G5.

hoping that manufactuers, hobbyists, and technicians will use the 900

Desired AM Station (kHz) - 900 kHz = Image Station

The images I am getting here locally in Virginia Beach, VA on LW is

150 kHz = 1050 kHz *WVXX -AM
210 kHz = 1110 kHz *WYRM-AM
330 kHz = 1230 kHz *WJOI -AM
410 kHz = 1310 kHz *WGH-AM
450 kHz = 1350 kHz *WGPL -AM
500 kHz = 1400 kHz *WPCE-AM

AM Band Images that are annoying

550 kHz = 1450 kHz
650 kHz = 1550 kHz

You are seeing a problem that is common to many inexpensive radios.
If you tune down 900khz from a strong nighttime station on the 6mhz
band you will hear image signals too. The solution is to pay more for
a better designed radio.
