In other words, it is a distribution, not an image.
The 'distro' contains a proprietary compressed file.
Using a torrent client on 'http://hampi.radiowaves.ca/HamPi%20Image%20v1.0.torrent',
I obtained a folder ('HamPi v1.0 by W3DJS'), containing:
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).

'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.
