'W3DJS Raspberry Pi Ham Radio
Image Distribution
v2.0 Released'
In other words, it is a distribution, not an image.
The 'distro' contains a proprietary compressed file.
Using a torrent client on
'',
I obtained a folder ('HamPi v1.0 by W3DJS'), containing:
total 3.7G
4.0K CONTRIBUTE.TXT
3.7G HamPi_v1.0.img.xz
4.0K HamPi_v1.0.img.xz.sha256sum
4.0K HOW_TO_FLASH_IMAGE.TXT
4.0K LICENSE.TXT
456K README.docx
?12K README.TXT
4.0K UPGRADE_FROM_W3DJS_IMAGE.TXT
?Because '
HamPi_v1.0.img.xz' is a proprietary
compressed format,
balena-etcher is required to un-compress (and to place the disk
image on SD media).
In this scenario, 'dd' will not work as it is expecting an image
(.img), not a
'compressed disk image' (.xz).
Carlos:? You are correct in part:

I would be careful with assuming dd will work in macOS. I have not tried on this particular image but have tried on others. Even though there are different *nix flavors, the filesystem needs to be supported. I previous tried on a Pi project I had I could not use dd because the image I needed to write was not on a format the Mac supported. I use Balena Etcher on my Mac. It provides a nice interface that makes creating bootable SD cards a breeze.

'dd' will work in Mac-OS, but not using this proprietary compressed
file (HamPi_v1.0.img.xz).
It seems to me that 'balena-etcher' uncompresses and transfers the
.xz file, 'on the fly'.
?I have no difficulty transferring a disk image (.img) to filesystem
media using 'dd'.
?It seems, in this distribution, balena-etcher is
required
for installation.
