The Inner Whalebacks (Latitude 61º55'14'' and Longitude 113º43'46''W) is a set of islands located in Great Slave Lake, the 10th largest lake in the world and the 5th largest lake in North America (and larger than Lake Ontario or Lake Winnipeg or Lake Erie).  On these islands a Daniels weather repeater system was installed around 2004 (images are at:  http://www.ykars.com/gallery/index.php/2004-Images ) by the GNWT Department of Municipal and Community Affairs (MACA) and Environment Canada with assistance from the Yellowknife Amateur Radio Society (within the limits of their licences; some of the members involved were also qualified radio technicians and acting as such rather than as amateur radio operators). 

The intent of the project is to beam maritime weather forecasts up the East Arm of Great Slave Lake.  The East Arm is sparsely populated, although there is the community of Łutselkʼe with a population of about 330 in 2017.  The area is very popular with recreational and Indigenous fishers (it is a known spot for northern pike and lake trout).  This service is an example of the far reach of the Yellowknife Amateur Radio Society and its service beyond Yellowknife to local communities.

The Yellowknife Amateur Radio Society travels out to this location every year to inspect the repeater site and carry out basic maintenance and report on the state of the repeater.  Members have gone out in the summer on boats or in the winter on snowmobiles.  The Society's QSL Card is an image from 2004 of Chris Cameron at the site when it was being set up.  The images on this page are from a 2009 inspection trip in the summer with the Coast Guard Auxiliary.
