In the July/August 2014 issue of "Potentials" (which is the magazine for
student members of IEEE), three professors from the University of Hawaii
present a general overview of CubeSats.

The authors then describe their and their students' designs (and success)
in building  a CubeSat designated H2 (Hooponopono) to replace the RADCAL
satellite (used for radar calibration) which ceased communication in May
2013, 17 years after its predicted life time of three years.

Among other things, I find it interesting that the team members are using
Ham Radio Deluxe and a Yaesu GS-232 rotor controller for tracking at their
ground station. The ELaNA  program also gets a prominent mention. The
satellite transmits and receives on 437.22 Mhz, so the frequency
coordination and licensing were handled through the IARU and FCC.
