Established in 1942 surrounding Albro Lake, then several kilometres north of the town of Dartmouth, Nova Scotia.
It could receive from (and transmit to, through NRS Newport Corner) locations halfway across the world and stretching from Murmansk, Russia to the Falkland Islands.
The facility was instrumental in helping allied navies during the Battle of the Atlantic in combating the U-boat threat.
Dartmouth's growth during the post-war years degraded radio reception as the town became a city by the early 1960s.
The site of NRS Albro Lake is now occupied by Highfield Park housing development.
