Popular by virtue of being the only radio station, CFAO began broadcasting from the trailer court on the station in the early 60's with a 10 watt transmitter. It was run by a core of 20 volunteers offering music and news to the station and surrounding area seven days a week on 1450 kHz. Armstrong had up to three deHavilland Canada Otters operating from the DOT run airfield at any one time. The Otter Flight's duties ranged from logistical support, search and rescue, to "Flying Doctor" services. The "Flying Doctor" service was offered on a weekly and monthly basis to personnel stationed at Pagwa and Sioux Lookout. Medical evacuations were carried out as necessary. Dental services were provided on a bi-monthly visit by a Royal Canadian Army Dental Corps detachment. The station had limited recreational facilities, so hunting and fishing became quite popular, as did snowmobiling.
