  The calibration of Very Long Baseline Interferometry (VLBI) data has long
been a time consuming process. The Korean VLBI Network (KVN) is a simple array
consisting of three identical antennas. Because four frequencies are observed
simultaneously, phase solutions can be transferred from lower frequencies to
higher frequencies in order to improve phase coherence and hence sensitivity at
higher frequencies. Due to the homogeneous nature of the array, the KVN is also
well suited for automatic calibration. In this paper we describe the automatic
calibration of single-polarisation KVN data using the KVN Pipeline and
comparing the results against VLBI data that has been manually reduced. We find
that the pipelined data using phase transfer produces better results than a
manually reduced dataset not using the phase transfer. Additionally we compared
the pipeline results with a manually reduced phase-transferred dataset and
found the results to be identical.
