RATPAC Defined

Radio Amateur Training Planning and Activities Committee (RATPAC). Although not affiliated with the ARRL, RATPAC is made up of ARRL Section Managers, appointed ARRL field leaders, and other members of the amateur radio community.

We hosts Zoom presentations twice weekly for amateur radio operators worldwide, Wednesdays on general radio topics, and Thursdays on amateur radio emergency communications.

The presentation audience participates directly in the Zoom sessions and/or indirectly with video links (including YouTube) and related documentation sent out after each session.

Digital Mobile Radio

Digital Mobile Radio (DMR) for Hams located in the Pacific Northwest. Our focus is on our infrastructure, repeaters, servers and operation.

Digital mobile radio (DMR) is an open digital mobile radio standard with the primary goal of the standard is to specify a digital system with low complexity, low cost and interoperability across brands, so radio communications purchasers are not locked into a proprietary solution. The standard has become popular within the amateur radio community due to the relative lower cost and complexity compared to other commercial digital modes.

We are a c-Bridge based network of Motorola’s MotoTRBO repeaters located in British Columbia, Idaho, Oregon and Washington with our own direct connecting MMDVM servers as a secondary method to maintain contact with the network when outside of our repeater coverage area.

We operate 3 c-Bridges using 3 Washington data centers and more than 75 repeaters, 9 MMDVM, 2 Echo Servers and various backend support operations. We also maintain a SMS and APRS-D server. The HamWAN Microwave backbone is used where possible and we are coordinating our sites and efforts to help grow the HamWAN network.
