The Lilly Oak on the slip…

The fishing vessel Lilly Oak sits on her cradle on the slip at MacDuff Harbour, Scotland. The slip is a long sloping concrete ramp (image coming soon) used to haul boats out of the water for repair and repainting. The cradle that supports the ships runs on railway lines on the slip.

The meaning of ‘GR’

If you visit the United Kingdom and see a post box (like the one below) with ‘GR’ on the front, this means that the postbox was installed during the reign of King George V (1910-1936). In those days we British folk used to build thing that would last for a long time. The ‘G’ stands for George of course and the ‘R’ stands for Rex (Latin for King).

The post box below is still very much in service and it is located near to Banff High Street and long may it remain there. Let’s hope this post box and many other things can survive the complete pillock who is currently living at No 10 Downing Street.

The Harrison Clocks

Without John Harrison’s clocks we would have been, quite literally, lost at sea. Nobody could underestimate the importance and brilliance of John Harrison’s clocks (or marine chronometers as we know them these days).

I satisfied a long-held ambition this morning when I went to see John Harrison’s beautifully made (and priceless) clocks at the Royal Greenwich Observatory. All the clocks Harrison designed and built are still working just fine……ticking away happily in glass display cages in a quiet corner of the observatory.

And, John Harrison (1693 – 1776) was a son of Lincolnshire. So am I but I have yet to knock out a clock or two!

The T1154 and R1155

The T1154 transmitter and the R1155 receiver were the first radios I used to transmit and receive signals (in my teens in the 1960s). These transmitters and receivers were used in Royal Air Force heavy bombers and other aircraft during World War 2. These transmitters and receivers used Morse code and the morse code signal used to ‘chirp’ (sounded a bit like a demented bird on drugs!). Some ‘chirping’ Morse code here.
