Re: Morse code
Thats right John, forgot to mention, this was on the Vhf radio, i used it quite a bit when crossing the channel from the Island in a small boat , 26ft, apart from the RDF battery operated by hand kit with earphones, echo sounder, and chart, it was the part i enjoyed. now i suspect they plug in destination, auto helm on, G & T, and away they go, chart plotter as well, them and many others all travelling down the same waypoints. Just hope they keep good look out, kt

Re: Morse code
Before the advent of GPS at sea you had Omega and Loran which were both long wave radio locating devices. Omega if I am correct was the U.K equivalent of the USA Loran system. Both required the carriage of special plotting charts with l.o.p's of the radio signals overlaid on the charts. Loran was still going up till quite recently with the systems receivers upgraded to give direct lat/long readout. Sailed with both systems but the technology behind them is lost in the dim and distant past. If you could not get star or sun sights on ocean voyages they did at least give you a reasonably accurate position, claimed to be within a couple of miles of actual position as opposed to GPS which is accurate to within metres.

Re: Morse code
That’s the one trying to remember Loran. Thanks. Eureka before I go to bed. That’s the one thinking of Keith never sailed with it, and never heard of omega apart from a watch I used to have. There’s always someone on here who can remember as ones own fades. Thanks John. The company I served my time with wouldn’t put a star reduction tables on board and they came out during the war for the US Air Force. Was always the hard way with them. Cheers JS.

Re: Morse code
Bet you couldn’t send that on a lifeboat heliograph especially if the sun kept going behind clouds. JS

Re: Morse code
Nah, that’s why it was made with metal and not glass, so it wouldn’t crack. JS
