The K4USD Network
Administrator: John Burningham, W2XAB
w2xab@arrl.net
The K4USD Network is operated by the US Digital Amateur Repeater Club (K4USD) using multiple c‑Bridges™ to interconnect Motorola Mototrbo™ repeaters together and peering with other DMR bridge providers including DMR-MARC, DMRX, DMR+, Brandmeister, TGIF, QuadNET and 27 other regional DMR networks.
Our main c-Bridges™ are located in a multihomed data center near Dayton Ohio on dedicated servers. We currently support repeaters in 16 states and DC in a managed network; we accept all amateur Mototrbo™ repeaters (XPR8300, XPR8380, XPR8400, MTR3000, SL1000, SL5700, SL8000) and do not charge any fees, although we do accept donations.
We offer a wide variety of general public Talk Groups (TGs) listed below. We also offer some local/regional TGs not listed below on request. If a repeater owner/operator wants a TG not listed, they should contact the administrator.
Repeater users should contact the repeater owner/operator for the TGs available on the repeater and time slot (TS) used for each TG. The TS listed below for the network wide TGs are the network default configuration which may vary for specific repeaters.
The K4USD Network plans on having direct connectivity support for the MMDVM and OpenSpot in the 3rd quarter of 2019, stay tuned for further information
The K4USD Network will be terminating Text Messaging across our network effective May 1st, 2019 because of a number of users transmitting GPS data and Talker Alias. Users will still be able to use Text Messaging locally on a repeater.
Note: On January 1, 2020 the K4USD Network will start BLOCKING any traffic with invalid Peer IDs, we are currently blocking invalid Source IDs. This means if a HotSpot or repeater is using an unassigned ID or the network they the connected with is not forwarding the valid Source ID they will be blocked.
