Great piece of work, Ed. Well done.
I agree.
Here are some comments.
Consol was still in use in 1961 with five operational stations - N Ireland, France, Norway, Spain (2). Reference CAP 59 "Consol A Radio Aid to Navigation" HMSO fourth impression 1961. I do not know the exact year that Consol (aka Sonne?) was introduced.
Details about RDF (in its various forms) missing. Dating from the 1920s?
There is no mention of Bygrave or sliderule.
The HP35 calculator was introduced in 1972 just one year after HO 229.
December 1883 Longitude of New Zealand determined by electric telegraph. (https://paperspast.natlib.govt.nz/newspapers/EP18831221.2.17)
The NTP protocol ( c 1985 ) allows me to display atomic time on my phone. It even allows the local commuter train company to proudly boast that its trains keep atomic time. Staff with smart phones strapped to their wrists is in my opinion an overkill! To be fair to the train company I think that the decision to strap phones to wrists is made by younger employees who do not know what a wristwatch is and who probably cannoty read analogue clocks. I would be more impressed is all staff consulted fob watches.
Finally, to show my bias, is Norie important enough to rate a mention?
