what does column C B M S = mean? KJ4VVU
The CBMS in the DX cluster window is an indicator of whether you worked a spotted station by C
ode, and the exact same S
tation that was spotted. It's my understanding, as an example, say station ZL1XX is spotted on 20 meters running CW, HRD will compare the spot information to your logbook and will let you know by a Green check mark or Red X, if you have ever worked that country, on 20 meters, using CW, and whether you have worked that exact station.
