After 70 years of existence, the Society has accumulated a tremendous amount of information and data, not only about the Society itself but also about the industry in general. Of course, until the ‘90s most of this information was in paper form with the earliest material somewhat yellowing with age. Over the last 12 years I have scanned, OCR'd and edited all our CTE and Broadband Journals and made them available as downloadable PDF files. The result is a complete archive of the Society’s Journal from 1946 to date, all available to members as a download from the website at http://www.thescte.eu/downloads . Over the last few years, we have also provided an interactive page-turning version of each issue which is also available online. We intend to progressively make the complete archive available as page- turning versions. On the website, you will also find some fascinating documents from 1945 showing how the Society was first set up together with copies of every Annual General Meeting up to the current day. We also have copies of ‘Crosstalk’ which was aimed at technicians and produced from 1998 to 2002. Also available online is an interesting archive of CableVision News. This was originally published by the Cable Television Association (CTA) starting in 1973 and provides an interesting insight into cable at a business level before the introduction of the new cable franchises in 1983/4. With such a valuable and fascinating collection of information from the past, we would encourage all our members to take a peek into the archives. To give you a taste of what’s on offer, we have decided to re-publish a selection of papers from the past. On the next page, you can read 'Passive Components for Cable Television Systems - Part 2' by Chris Swires and edited by Ray Seacombe, published in Vol.11 No.7 of CTE. We have tried to keep the original format and apologise that the resolution of some of the figures are not to our usual standard. This provides an interesting 'compare and contrast' to the preceding article on the design of a modern Ultra-Wideband power divider. From the Archives by Dr. Roger Blakeway
