FM 91.1 CMS (callsign 1CMS) is a multilingual community radio station broadcasting to Canberra in languages other than English from studios in the suburb of Holder. CMS is a member of the National Ethnic and Multicultural Broadcasters Council (NEMBC) and the Community Broadcasting Association of Australia (CBAA).
The policy of CMS is to encourage all languages to broadcast for at least an hour each week, providing time on an equitable basis. Programming priorities include youth, women and emerging communities. 
The EBC (Ethnic Broadcasters Council) as it was then called, started broadcasting by purchasing airtime on community station 2XX. Up to 25 language groups were broadcasting for half an hour each per week during the 1980s. Discontent in the early 1990s saw the EBC and 2XX sever ties with each other. EBC were off the air until August 1992 when they were able to apply for their own test broadcast licence. EBC were back on air on Tuesdays and Fridays using the facilities of ArtSound FM.
In 1999 the EBC received a full time test licence to broadcast on 103.5 FM. Soon after the on air identity was changed to Canberra Multicultural Service and the frequency moved to the present 91.1 FM. Then an application for a full broadcasting licence was applied for. This was granted on June 15, 2001. 
FM 91.1 CMS now has programming in around 30 languages. The station broadcasts live from the Canberra Multicultural Festival each year. Internet streaming was introduced in 2008.
As of 2008, the station broadcasts in the following languages: 
- Chilean Spanish
- Cypriot Greek
- Belgian Dutch (Flemish)
Satellite programming from Deutsche Welle, Radio France International and the National Indigenous Radio Service is also carried.
