CHAK was launched in 1960 as a local community station in neighbouring Aklavik on AM 1230. That same year, a new station was being built by the CBC in the new town of Inuvik to replace the old station in Aklavik. The new CHAK went on the air on November 26, 1960 on a new frequency, 860. The station was now part of the CBC Northern Radio Service. CHAK received CBC news and topical programs by picking up CBX 1010 (later 740) Edmonton and relaying the broadcast. Tapes recorded in Montreal were also flown in on regular airline flights. Eventually the station was linked into the primary CBC network feed.
During the network's primary local programming breaks, CHAK airs the same programs as CFYK in Yellowknife, including The Trailbreaker on weekday mornings, the noon-hour program Northwind, Trail's End in the afternoons, and Northern Air on weekend mornings.
However, the two stations both diverge from Radio One network programming in the afternoons, producing separate programming streams for their local First Nations communities. CHAK airs Nantaii in Gwich'in from 1:00 to 2:00 p.m. and Tusaavik in Inuvialuktun from 3:00 until 4 p.m.
CHAK has two rebroadcasters in Nunavut, both in communities where CFFB, the CBC North station in Iqaluit, also broadcasts. This is done in order to provide CHAK's afternoon First Nations programming to these communities, as CFFB's afternoon schedule concentrates on programming in Inuktitut.

1 In Paulatuk, Tsiigehtchic and Ulukhaktok, CHAK's signal is rebroadcast on transmitters owned by local community groups rather than by the CBC itself. Three further community transmitters — operating on 107.1 in Colville Lake, 107.1 in Sachs Harbour and 100.1 in Old Crow, Yukon — are unlicensed by the CRTC under its exemption for low-power community radio undertakings.
2 Rebroadcaster CBAK originally received CRTC approval in 1985 to operate a low-power transmitter at Aklavik on 540 AM. In 1998, CBAK received approval to change frequencies from 540 AM to 1210 AM with the power remaining at 40 watts.
4 On May 8, 2013, the CBC received CRTC approval to convert CBQI Tulita from 920 kHz to 100.9 MHz. 
5 On September 11, 2014, the CRTC approved the CBC's application to convert CBAC Tuktoyatuk from 1150 kHz to 99.9 MHz.
