your hat is not working because you have not installed the driver. You get data in signal k from the hat because you have the AIS simulator enabled, look at those crazy boats in the Adriatic, and you get position from another gps.
You will not be able to install the driver until you enable the SPI interface. Is there any reason to do not enable SPI? are you getting any error?
