There was at one time a video of the last link, but it appears the hosting site is no longer live. There are other lecture slides on radio interferometry available from the Synthesis Workshop site: https://science.nrao.edu/science/meetings/2014/14th-synthesi...
However, here's a few resources I remember and was able to dig up.
1) A presentation from Max Plank University, which has one of the strongest radio astro programs around: https://www.mpifr-bonn.mpg.de/3244052/IMPRS_BB_HRK5.pdf
2) Presentation from ASTRON, an interferometric array in the Netherlands, part of the Netherlands Institute for Radio Astronomy: https://www.eso.org/sci/meetings/2015/eris2015/L6_Heald_cali...
3) George Moellenbrock's slides from the 14th Synthesis Imaging Workshop (hosted by the National Radio Astronomy Observatory) is pretty detailed on calibration specifically: https://science.nrao.edu/science/meetings/2014/14th-synthesi...
