Hi Alan,
Since you now have a .gxf file, here are my testing steps that I just
performed locally:
QGIS relies on the GDAL library for raster/vector access. When hitting
a new format and wondering if QGIS can read it, always start by going to
https://gdal.org and scroll down the page and look for your format: for
example, you will see "GXF" listed there under raster drivers:
http://download.osgeo.org/gdal/data/gxf/ Give that a read as a start
always (put another way: *always* start by reading the GDAL driver page
for your format, read the entire driver page as it usually contains
important information).
From reading that, now you know that the GXF driver is always built by
default, so that means you should be able to use QGIS to read your QXF file.
(if you prefer the commandline, executing 'gdalinfo --formats' on your
local machine should return the GXF driver in the long response, and
then you can try 'gdalinfo myfile.gxf' )
You can actually use GDAL test data to verify this: download
"sample.gxf" from http://download.osgeo.org/gdal/data/gxf/
Open "sample.gxf" in QGIS ("Add Raster Layer") and it should look like:

Hope these steps help! cheers from the east coast of Canada,

Thanks for the suggestions.
Have tried exporting the .grd files as both gxf and ers files but
neither open as rasters in QGIS…..

Can someone help me with the loading of .grd files
(geophysical imagery) into QGIS? I’ve tried loading this as
a raster layer as well as simply trying to open the file,
but both routes tell me the file format isn’t recognised.
Thanks!
Is this a "Surfer Grid file"? https://fileinfo.com/extension/grd
And if so, did you try this approach:
https://gis.stackexchange.com/questions/23002/how-to-visualize-grd-files-in-qgis/93209
This article:
https://trac.osgeo.org/gdal/ticket/4887
suggests that GDAL may support a related (public) exchange format. Can
you export from your software to this format (.gxf)?
