I just completed the Introduction to Emergency Communications self-study course and I was prepared not to be impressed. I was impressed. The course is well written and has good, solid information. I am a local volunteer leader and have been through the Oregon Amateur Communications Emergency Solutions course (taught in it), AUXCOMM, Skywarn, and everything I can get. Space is given to other radio services like GMRS and MURS and digital modes are mentioned (hard to keep current). This acknowledges the shift from radio-with-a-ham-attached to volunteer-with-a-radio. AR licensees can do more than show up with a go-box. This is a good course for both the newbie interested in public service and an experienced volunteer.
I was annoyed at the space spent on ARRL field organization, wearing ARRL clothing, the National Traffic System, and the ARRL radiogram. Most of the questions I missed were in these topics since I pay no attention to section managers, radiogram field, etc. I got past all that and can recommend the course to other volunteers.
I am now into the Public Service and Emergency Communications Management for Radio Amateurs course which was written by the ARRL marketing department. There is emphasis on the sale of amateur radio rather than being good volunteers. I will power through the course, but I don't feel like I'm learning as much as the Introduction course.
If you have time—and we all have time at this writing—I recommend the first course.
