      This simple AC-Simulation (see Test2.sch) shows IMHO wrong results (see QucsAcSimulationTest.jpg). The frequency with gain 0.5 should be at ~1 kHz, not at ~600 Hz. Am I doing something wrong or is this a bug.

      As reference, I calculated it manually and checked it with https://www.redcrab-software.com/de/Rechner/Elektro/RC-Grenzfrequenz-Rechner.

      Qucs version used: QucsStudio 4.3.1

        Oh sorry, I realized my mistake. I would like to delete the report, but that does not seem to be possible.
