OFCOM decision

OFCOM decided that Channel 5's programme "The Nightmare Neighbour Next Door" broadcast in October 2016 did not contravene their Broadcast Code. Page 101 of the bulletin, link below, refers. OFCOM received 52 complaints that the programme was "Materially Misleading" - there were several suggestions in the programme that there is a link between amateur radio transmissions and cancer.

Antenna Matching

http://www.g3ynh.info/zdocs/z_matcing

The pages on impedance matching (Parts 1 and 2), including the analysis and operation of L, T and Pi networks, are excellent. The treatment of the subject includes a tiny bit of maths (R, G and jX), but that adds to the excitement.

Some Standard Time Sites

In January 2012 a decision was to be made on retaining or dropping the leap second, the latter being the USA's proposal. The decision that actually came out was to postpone the decision until 2015!

A problem with retaining the leap second is that they will become problematically more frequent as the years go by. Currently one leap second is introduced every year or two. Centuries from now, the Earth's rotation will slow down to such a rate that several leap seconds a day will be necessary to keep Atomic Time in step with Solar Time. See the NPL website for further detail,
