In this note we present the spectrum measured with the AMIGA in-ll featuring the no observation of a second knee break from 1017:2 eV.The event reconstruction, constant intensity cut procedure, energy cal-ibration and exposure calculation used to obtain the spectrum are de-scribed. A few new ideas were introduced along the way including theextension of the spectrum down in energy by cutting at a zenith angleof 30 and the exclusion from the spectrum of events falling less than100m from a station.
