The Digital Traffic Network (DTN), formerly known as NTSD, is a digital network operating interoperably with NTS manual nets. It operates 24/7 on HF Pactor and VARA, and VHF Packet. Using auto forwarding and auto calling, messages are relayed throughout the US and Canada as well as to international destinations. Note that FCC regulations restrict third party traffic to those countries with whom the US has third party agreements. Check the FCC website for a listing. However messages from one amateur to another amateur are generally not considered third party and are permitted. Station KW1U operates on both HF and VHF as a New England hub with connections to hubs throughout the US as well as internationally, and amateurs are invited to use the station via either HF or VHF for relaying message traffic.
For those interested in getting involved with Packet messaging check with Michael WZ0C for more information about Packet operation in this area. Michael operates a Packet BBS on VHF as well as VARA on HF and operates a GTE Gateway between APRS and DTN.
