The IBI says the Government's proposed support schemes for the sector are "unfit for purpose."
The Independent Broadcasters of Ireland is calling for urgent Government intervention to level the playing field.
The group is made up of the country's 34 independent radio stations, who make up 70% of listenership.
It says there's currently no State support for core news and current affairs services in the independent sector, which is competing against other outlets which have benefitted from major Government intervention in recent years.
It adds the Government's proposed support schemes are "unfit for purpose".
The Chief Executive of the Independent Broadcasters of Ireland, Michael Kelly says: "Because there are no workable or accessible support currently for the vital news and current affairs services our stations provide to listeners, we need all TDs and Senators to intervene urgently to ensure fair and proportionate support for our sector and its listeners, and a level playing-field.
It is vital that the sectors needs are taken fully into account.
Our Members have all signed a letter to the Taoiseach, the Tánaiste and the Leader of the Green Party calling for immediate action."
