In addition to a standard analog transmission, CFTR is simulcast on the second HD digital subchannel of CKIS-FM, and is available online.

Because 1540 is a clear-channel frequency assigned to stations in the United States and the Bahamas, CHFI was authorized to broadcast only during the daytime.

Once CFTR gained ratings supremacy, CHUM dropped Top 40 in favour of an adult contemporary music format in 1986.

At 6 am on June 7, after playing Phil Collins' "Against All Odds" (which was the #1 song in the countdown) and Starship's "We Built This City" (which also ended CHUM's Top 40 era in 1986), CFTR adopted its present all-news radio format as "680 News".
