HERITAGE CKOO CALLS RETURN TO THE OKANAGAN
Castanet (Avenue Radio) has changed the call letters of recently acquired CJUI 103.9 in Kelowna to CKOO "Okanagan Oldies", The CKOO calls were originally at 1240 in Osoyoos and rebroadcaster CKOO-1 1490 in Oliver from 1966 to 1991. After that they did a bit of travelling, first at 98.5 in Montreal from 2000 to 2004 and then in the early 2010's at an Aboriginal station in Broadview, Saskatchewan which has since gone dark.
