switching to a new transmitter in the winter of 1930-1931, the station boosted its power to 200 watts from 25 Watts and it could be received as far away as Europe, South Africa, and New Zealand on either 6.095 or 11.81 MHz, and would later broadcast on 24.38 MHz, as well. In 1932, the station's power increased to 500 watts. From 1933 to 1936, CKGW and VE9GW were leased from Gooderham & Worts by the Canadian Radio Broadcasting Commission, which used the station as one of the broadcasters of Northern Messenger, a mailbag programme aimed at listeners in the Far North, which the CBC would continue to air into the 1970s. CKGW became CRCT and, in 1935, VE9GW's call letters changed to CRCX. In 1937, both stations were purchased by the new Canadian Broadcasting Corporation. CRCT became CBL and CRCX was closed down in 1938. The station mostly broadcast on 6.095 MHz but, at various times, transmitted on 11.81 or 24.38 MHz. Former callsigns CBLA is a former callsign of a defunct CBC radio transmitter in Atikokan, as well as the defunct CBLR in Red Rock that now belongs to CBLA's rebroadcaster in Parry Sound.
