I am using my K2 remotely with N1MM for CW operation and Ham Radio Deluxe (HRD) for other modes. My problem was that I did not have good rig function control with N1MM. So I fnally started reading the N1MM manual and saw that you can encode rig control functions in the Macros, accessed via the function keys. So I added buttons for Antenna Selection and for Tuning the antenna match. This gives me the basic rig functions I need while cruising the Bands working CW.
