The K band and the Q band single-frequency single-polarization modes are available and a recording rate of 1024 Mbps (total bandwidth of 256 MHz) will be open for the 2019A CfP. Dual-polarization with KVN and simultaneous multi-frequency mode with KVN will not be available for the 2019A CfP. Two new observation modes are available from the 2016B season; fast antenna nodding mode and 1-beam hybrid (KVN multi-freuquency support) mode. Another two new observation modes are available from 2018B season; C2 mode and Wide-ﬁeld imaging mode. Details are summarized in the Appendix A and B, respectively. From the 2019A season, astrometry observation mode is available, as summarized in Appendix C.
