NET amateur radio operators who want to be official NET AROs (Amateur Radio Operators!) need to be designated by their Team Leader and certified by NET ARO Radio Training Liaisons (RTLs). A description of the ARO Standards and Certification process and information on how to find your RTL can all be found from the Portland Bureau of Emergency NET page for this purpose. You will also find the most current version of the ARO Task List on those pages.
Some of the tools you will need or want as an ARO, however, are available here. You can find radio manuals and cheat sheets, templates for programming your radio, information about antennas, and many more useful resources. These are shared in the following Google Drive folder:
Finally, there are radio nets and practice opportunities specifically designed for Portland NET amateur radio operators. You do not need to be an official ARO to participate! Below and links to other pages that describe these.
