The concept for First Response Radio was developed by HCR in 2001 and first deployed after the 2004 tsunami in Banda Aceh, Indonesia. The Rapid Response Radio Unit (RRRU), as it was then called, is a portable radio broadcasting system small enough to fit in a suitcase with a team of radio producers specifically trained to quickly broadcast critical information to communities following a disaster. FRR and HCR continue to contribute to each other's activities in training design, training delivery, deployment and research and evaluation.
