The Denver ARES community decided in July, 2017, to learn digital communications so we could better serve our served agencies: the American Red Cross and the Denver Office of Emergency Management. There appears to be no protocol common to all ARES groups, so we chose to focus on Outpost Packet Message Manager. We are also working on getting proficient with Winlink Express and FLDIGI.
Outpost PMM has pre-made ICS 213 and 309 forms, as well as ARRL National Traffic System (NTS) forms to make message construction much easier and more efficient.
Ben, K0YDS, has been successful setting up his station for Outpost and Winlink/Winmor and explains the process on this page.
