OK Jim,

I gave it a look.

I have to wonder from the start, and in the context of Xtal sets that
are usually employed for BCB, where the author decided that a typical
antenna exhibited 50 Ohms resistance and 40pF capacitance.

That was the first of a number of similarly random values assigned to
components that has me drawing up cold. From that, I have to wonder
what the value is in the practice of transforming those values.

I think that you need to ask the author. I just wanted to add some other
opinions.

I would say that he used some ideal values as a place to start with.
Kind of a 'what if.'
