After 6 months of steady progress, I am nearing my first SOTA activation via CW mode. My goal for my First MG (hihi) is to use all VHF in obtaining that distinction. If one were to use VHF for the first 4 QSOs and then switch to HF/CW mode for the remainder of the activation would that invalidate the all VHF status?
If the all VHF status were to be lost using HF another option would be 6m CW but I do not see many using it on activations. Any guidance on 6m CW operations welcome!
