Universal Radio is a project of Tacno, a member of my squad team. It is actually in beta test and the LotAtc integration is in progress (not full working yet).
The principle is a TS3 plugin + DCS export file on client, then it will follow the DCS radios and simulate distance, relief… like TARS or Aries radio.
Radio client need to be connected to a server (not necessary the DCS one) to work.
