Hi, Dave - I worked at Gartner for 13+ years, in the information security practice. Gartner has about 30 different hype cycles, they were always a lot of fun.
I once put together a Ham Radio hype cycle - there were about a half dozen hams at Gartner .Back then SDRs were emerging technology, now I'd probably put Open Source Transceivers (like the TenTec Rebel) there. I think we had electronic QSLing there, too - that would now be coming out of the Trough of Disillusionment and SDRs further up the Slope of Enlightenment!
