Straight Line Frequency Capacitor

I still can't get to my project yet because of the house d-i-y stuff which is doing my head in at the moment.

You and me too! But at the end of the day, there comes a time when a bit of R & R is required: and that's when I put down the D-I-Y tools and sit down with a pencil and paper - and test ideas.

Thanks for the link to the article on bandspreading. Haven't read it in depth yet, but it looks like an interesting and informative read.
And in it, I did note that Mr. F. E. Terman gets a mention. I have three books by him: 'Radio Engineering'; its successor, 'Electronic & Radio Engineering (4th. ed.)' and 'Measurements in Radio Engineering'. Although his work 'Electronic & Radio Engineering (4th. ed.)' is substantially thicker than its predecessor, in many places its analysis is quite shallow compared to its predecessor and some classical topics are not considered at all. However, 'Measurements' is an enlightening read. Overall, I would recommend these three books to anyone who likes to 'dig in' to the theory of Radio.
