I will do my best to check this. I am taking some days off work to do
some experimentation as from tomorrow. The test was that of a free
resonator with no link coupling.
BTW, in *NO WAY* do I claim this is the only model that works or
indeed that it is necessarily the best. However, the fact that it
exhibits distributed circuit behaviour while still allowing lumped
frequency calcs means something must be getting close.

Yes. Over the next few days. I will post results. I will do all
possible measurements on this model first before altering the
inductors.

No :( I will do so.
Thank you. A plea to all - let's try and understand this thing for
once and all. That is my sole motivation.
Many Regards,
