owenduffy.net rework

With the closure of VK1OD.net as a consequence of an enforced change of call sign, a monument to the growing emphasis on train spotting in ham radio, owenduffy.net is being reorganised.

It will essentially be a blog site with a mainly electronics focus, but less ham radio focussed than was vk1od.net.

Articles will be shorter, and expose less proof / derivation / evidence to better meet the needs of modern people who I am told just don’t have time for all that stuff.

Some meatier topics will appear as a series of bite size articles to better fit the concentration span of modern readers.

Nevertheless, there will be some citations, but I will keep them to a minimum.

Excuse the large extent of self citation. It is not done for self promotion, but to acknowledge that some material is based on earlier work, some of which may be offline… and to remind me of where to look if I need to follow-up comments on the article.
