The Electricity Act 1898 required that meters are certified for a finite lifetime and in domestic premises must be replaced when that time has expired. Induction meters like your are generally certified for 10 years, after which they must be replaced. It may appear to be working OK, but it's the...

The second set has a mixer oscillator that runs 465kHz (the IF) offset from the frequency being received, to create the IF signal which is then filtered, amplified and demodulated. That Oscillator radiates and some of that is received by the set receiving the SSB signal. Tune the second set...

My dad and I used to listen in to SSB transmissions placing a second, superhet receiver close to the main receiver, tuned so that it's IF oscillator acted as the BFO.

Final documents, i.e.those which the recipient should not be editing, should always be sent in PDF format, not in docx or odf format. Then you avoid the above problems and your clients are not required to have MS Office, or indeed any WP software at all. MS Word, OpenOffice and Libre Office can...

Not if the aircon is running, it condenses out and drains away. Aircon will DEmist the windows in a car, that's one of its major benefits

I was at UCL from '73 to '76 and we had our own computer centre with an IBM 360 running HASP on OS360. We learnt Fortran ( I later taught myself PL/1 and used that for coursework) and we had a couple of 029 card punch machines to prepare our own decks, which we then took to the basement of the...
