And, the fact that in Canada one cannot use home made transmitters until
they pass the advanced test likely is not a significant factor here.
Canada
is a small country, and over the years there's rarely been technical
material
published in the few Canadian ham publications. So we look to the US and
the UK for technical material, and they don't have such limits on what
one can build.
==============================
In the UK a Foundation Licensee (entry level) is not permitted to operate a
homebrew transmitter except when it is an approved kit.
This means he/she can not build and operate a transmitter from a published
design with bought components ,but is allowed to build a transmitter with
design and all components supplied by a reputable 'kit-house'.
As so often with this type of rules ,proper policing is hardly possible .
