WR3IRS is the club station license for the Interstate Repeater System, an affiliation of DMR repeater owners/operators. The WR3IRS repeaters are linked to each other, and to other repeaters worldwide.

The WR3IRS repeaters are grouped into regional networks. Each repeater in a given regional network has the same connectivity and talkgroup plan as all other repeaters in the same network. The regional networks, and their parent network, are as follows:

K4USD c-Bridge

      Delaware Valley c-Bridge Network

      Penn-Mar DMR Group


     Delaware Valley Brandmeister Network

     Northeastern Pennsylvania (NEPA) Brandmeister Network

In addition to those repeaters signing WR3IRS are a number of repeaters which collectively comprise the Penn-Mar DMR Group. The Penn-Mar DMR repeaters and the WR3IRS Delaware Valley c-Bridge repeaters are on the same parent network (K4USD c-Bridge), and share a common talkgroup serving Pennsylvania and Maryland as "local 8".

The TriState talkgroup (NJ/NY/PA) is made available full-time on the WR3IRS Delaware Valley c-Bridge repeaters by NJ-Trbo as "local 2".

Use of the WR3IRS repeaters is open to all licensed amateurs. Unless otherwise stated, all repeaters use Color Code 1. Please adhere to the Talkgroup Usage Policies applicable to each network as detailed on this web site. If you are new to DMR, aside from owning a DMR radio, you will need to register for a DMR User ID and program it into your radio before attempting to access any amateur DMR repeaters.
