To *almost* MK2R capability ... there are some headphone switching
options and a couple of advance control features that can't be
duplicated. However, by using an MK II and a DK II with micro2R
one has even more flexibility for digital mode (RTTY) contesting
including support for simultaneous dual receiver operation that is
not available with MK2R/MK2R+.
