Posted on by

By Radio Officer Sandro VIALE – Italy

Dear Sparks,

on this review it is showed the prestigious receiver 1830/1 made by Eddystone in the 70s. On many ships this receiver was dedicated as “Emergency Unit”. First time I have used this radio I was on board M/V “Jolly Marrone” c/s IBIM, below the picture of the vessel and a short clip I recovered by an old VHS cassette where the receiver is on the right side of the rack (bottom unit). After the clip are listed some features of this equipment.
