NNBY was a non-profit corporation owned by the fourteen First Nations of the Yukon, and its Mission Statement was "...to reaffirm and maintain First Nation Culture, spiritual beliefs, language, traditional values, land and animals". Its founding Board members were Alan Buyck, Randell Tetlichi, Albert James, Richard Sydney, Dave Porter, Judy Gingell and Dave Joe.

To achieve its ends, NNBY would expand its radio coverage in future years to reach over 20,000 listeners in the Yukon, Northern B.C. and the Mackenzie Delta. To launch this initiative, NNBY applied for a radio network licence, which was granted on September 5th, and permitted the satellite delivery of "...native and English language programming to remote and underserved communities in the Yukon territory." The licence would expire on September 30th 1987.

1986
On January 10th, CHON-FM received approval to increase its effective radiated power from 0.6 to 49 watts, to change its frequency from 88.9 to 98.1MHz, and to move its transmitter to share a tower with CKRW Whitehorse.

1987
On June 30th, the CRTC renewed both CHON's broadcast licence and its network licence for a further four-year term, from October 1st 1987 to 31st August 1991.

1991
This was the year that CHON began building its network. Over the next several years, CHON-FM's expansion would largely consist of the station's receiving approval from the CRTC for it to assume the programming responsibilities of small local native and community radio stations, and to have their transmitters become rebroadcasters of the CHON-FM signal.

On April 19th, NNBY received approval to add three such rebroadcasters, each with an effective radiated power of 1 watt and broadcasting on 90.5 MHz. These transmitters were located in Beaver Creek, Keno City, Stewart Crossing and Tagish, all in Yukon Territory. The licences were for a four year term, to expire on August 31st 2005.

On June 14th, CRTC approval was obtained for CHON-FM to increase its effective radiated power from 49 watts to 81.3 watts, and to relocate its transmitter, thereby improving the station's service to Whitehorse.

On October 28th, the CRTC granted a native television network licence to a non-profit corporation, Television Northern Canada Incorporated (TNCI), to serve northern Canada for the primary benefit of aboriginal people in the North. Northern Native Broadcasting Yukon were full members of TNCI, along with the Inuit Broadcasting Corporation (IBC), the Inuvialuit Communications Society, the OKalaKatiget Society, Tagramiut Nipingat Inc, The Native Communications Society of the Western NWT, Then Government of the Northwest Territories, Yukon College, and the National Aboriginal Communications Society.

The Network would initially provide a service of 100 hours per week of programming, in up to twelve different languages. Some years later, TNCI would
become the Aboriginal Peoples Television Network.

1992
On February 19th, CHON-FM had its licence renewed for a further seven-year term, to run from March 1st 1992 to February 28th 1999. The station would broadcast 84 hours per week of local programming, of which 13.5 hours would be in seven Yukon aboriginal languages and 70.5 hours would be in English.

The Commission also determined that, under the provisions of Public Notice CRTC1991-63, and with CHON-FM and its transmitters having been licensed together as a radio programming undertaking, there was now no need to renew NNBY's radio network licence, which would expire on February 28th.

Also on February 19th, CHON-FM received Commission approval to add transmitters at Destruction Bay (on 98.1 MHz), Haines Junction (90.5 MHz) and Mayo Road Subdivision (98.7 MHz), Whitehorse. Each transmitter would have an erp of 10 watts.

On May 22nd, the CRTC approved three more transmitters for CHON-FM, at Burwash Landing, Old Crow and Teslin, YT. Each would operate on 90.5MHz, with an erp of 7.5 watts.

1993
Two more local societies surrendered their licences on February 4th in favour of their transmitters being taken over for the rebroadcast of the CHON-FM signal. These were at Carcross and Ross River, YT. They too would broadcast the signal on 90.5 MHz with an erp of 10 watts.

1994
On July 5th, the addition of CHON-FM retransmitters at Carmacks and Mayo, YT, on 90.5 MHz, was approved by the CRTC.

1996
Dawson City joined the CHON-FM lineup on July 31st, on 90.5 MHz with 10 watts of erp. On the same day, the CRTC also approved a reduction in power of CHON-FM's Destruction Bay transmitter from 10 watts to 2 watts, with a relocation of the transmitter, which would result in better service to this particular locality.

1997
New transmitters for CHON-FM were approved by the CRTC on August 28th for Atlin, BC (on 98.1 MHz), and Watson Lake (90.5 MHz) and Upper Liard (98.1 MHz), YT.

On November 21st NNBY received Commission approval for their main transmitter in Whitehorse to increase its effective radiated power from 81.3 watts to 4261 watts.

1998
CHON-FM's service expanded further on February 25th with the addition of a transmitter at Lower Post, B.C., operating on 98.1 MHz with an erp of 3 watts.

1999
On February 26th, the CRTC issued CHON-FM an administrative licence renewal from March 1st 1999 to August 31st 2000, "to consider the renewal of this licence following the review of its native broadcasting policy".

2000
On July 17th, the CRTC issued further administrative licence renewals to CHON-FM and several other native radio program undertakings and networks, from September 1st 2000 to August 31st 2001. The Commission said that it needed time to consider comments on various policy issues related to native broadcasting that it has published that day in Public Notice CRTC 2000-105.

2001
New transmitters for CHON-FM were approved by the CRTC on February 2nd, to be sited at Aklavik NWT and Good Hope Lake, B.C. The Aklavik transmitter would broadcast on 90.5 MHz, and the Good Hope Lake transmitter on 98.1 MHz, each with an erp of 10 watts.

On June 15th the CRTC gave CHON-FM and its transmitters a seven-year licence renewal, from September 2001 to August 31st 2008. The new licence included new popular music Canadian content requirements, and encouraged CHON-FM and other native radio stations to use programming from other native radio stations or networks as wrap-around programming after their daily sign-off.

On October 1st, Pelly Crossing, YT, became the newest location approved for a CHON-FM transmitter, to operate on 90.5 MHz with an erp of 10 watts.

2003
The CRTC gave its approval on April 23rd for CHON-TV to establish a new transmitter in Faro, YT, to broadcast on 90.5 MHz with an effective radiated power of 1 watt.

2006
Further expansion of the CHON-FM radio network came on January 27th, when the CRTC approved the station's application to add a new transmitter at Tsiigehtchic, NWT, on 90. MHz, with an erp of 10 watts.

2008
August 27th saw the Commission award CHON-FM, and its network of transmitters in Yukon Territory, British Columbia and the North West Territories, a new seven-year licence, to run from September 1st 2008 to August 31st 2015.
