RRI Extends Digital Network to Puerto Rico

Radio Relay International, an independent amateur radio messaging organization, has expanded its Digital Traffic Network (DTN) infrastructure to Puerto Rico. According to the organization, the DTN is a hybrid mesh network utilizing HF for long-haul traffic and VHF/UHF gateways for local emergency communications activities. Over the past year, according to RRI, the group has been providing training to volunteers in Puerto Rico as well as technical support and one-on-one assistance. 

During Hurricane Maria, it says, “one RRI volunteer alone handled over 2000 welfare messages out of the stricken area.” The system also makes use of Winlink and says it is fully interoperable and integrated with other emergency communications resources. RRI also sponsors the National SOS Radio Network and Neighborhood Radio Watch programs.
