The Radio Officers Association are holding their AGM at the Atlantic Hotel in New Street Chelmsford this year on the 26th/27th April (see link below).
For those officers not familiar with Chelmsford The Atlantic Hotel is almost opposite the famous 1912 Marconi building although, at the time of writing, this is shrouded in plastic sheets as the new owners are undertaking emergency remedial work to make the roof watertight and prevent further deterioration.
Please note that the International Marconi Day will be held on Saturday 27th April (nothing on the Friday) and will certainly be attended by radio officers who live locally.  They will be able to explain the three ship’s radio rooms on display.  Two are from the beginning of the 20th century and the third is post second world war.
