About the board based on Si4730 labeled “NE928-10A V:01”
This board is an AM (MW) and FM receiver. It is based on SI4730-B20. The PU2CLR SI4735 Arduino Library is compatible with it.
Unlike the PL102B board based on SI4730-D60, a very similar board and also supported by the Si4735 Arduino Library, the NE928-10A DOES NOT SUPPORT LW, SW and FM/RDS. Actually, judging by the Silicon Labs, the NE928-10A, PL102B or any board based on SI4730 device should not support LW, SW and FM/RDS. However, some tests with the PL102B breakout and IC SI4730-D60 have been received SW stations with success. The author of this document cannot guarantee that his experiments with boards based on the SI4730-D60 will work for you.

Video
The video below shows the “NE928-10A V:01” device working with the sketch SI47XX_02_ALL_IN_ONE_OLED. That sketch was built to work on SI4735-D60 and SI4735-A10. So, some functions will not work. To add the encoder and push buttons, follow the schematic below.
