There is also the issue of patent infringement.
Radio Electronics carried a contruction article many years ago ('80s)
where the author used the PCB inductor method in the project (UHF TV
Transmitter if I recall correctly).
RE had to publish a notice some
months later warning readers that using this project was infringing
on a current patent.  With luck the 17 year limit on that
patenet has expired. The patent would also have details on computing
the inductance I would think.
