I got to thinking the other day that almost all modern mid to high end AR rigs could constitute the basis of a quarter or semester college course. Most of them have manuals in the 100-200 page range and enough features/options/capabilities to keep one studying and scratching one's head for a semester. Possible areas of study could include: Controls and their function Fine points of rig subsystems (IF DSP, Keyer, ATU, processor, etc.) Interfacing to other systems (amp, computer, pan adapter, etc.) Antennas, antennas, antennas Operational techniques. Such a course would certainly be more interesting and useful than, say, a course in gender studies. OTOH, it would likely be a niche oriented affair. And on the third hand, it might be enticing to those studying science and engineering.
