[Heath] DX-100 Modification Identification Question

[Gary H. Harmon, Jr.]

Heath Modification Kit Model MK-1 (SB-10)

Improved Keying for the DX-100 Model MK-2??

DX-100 Loading Control Modification Model MK-3

 

In my DX-100 document files I have three Heathkit mods.  The MK-1 and MK-3
are identified and I suspect the Improved Keying modification may be MK-2.
Does anyone know for sure?
