It broadcasts on 101.9 MHz with an effective radiated power of 100 watts (class A1) using an omnidirectional antenna. The station also operates a co-channel repeater, CHAI-FM-1 in Candiac, also on 101.9 FM. The use of two transmitters is in order to protect several co-channel and adjacent-channel stations in nearby areas, the closest being CIBL-FM and CINQ-FM in Montreal, plus co-channel CJSS-FM in Cornwall, Ontario.[1] (CBMG-FM in Cowansville, a local repeater of CBME-FM that also broadcasts at 101.9, did not sign on until 2002.)

The station operates under a community radio licence and has a variety format. It opened in 1980.[2]

In December 2015, CHAI-FM announced plans to replace its two-transmitter system with a single transmitter, from a location southeast of CHAI-FM's main Châteauguay transmitter. The new transmitter would broadcast at 238 watts, with a directional antenna set on an east–west pattern, also to protect nearby stations as discussed above; this was due to synchronization and interference problems between the Châteauguay and Candiac transmitters, which is evident where the two transmitters overlap in an area between Lachine and Delson.[1]

The station is a member of the Association des radiodiffuseurs communautaires du Québec.
