I am not so familiar with 80m. At home I have no antenna for this band, from summits I have activated 80m just once.
Is there a center of activity for SOTA CW on 80m, anything like 7.032 or 10.118? Weeding through the spot frequencies of previous activations did not give a complete picture. 3.557 and 3.558 each appeared once in the last 72 hours.
Any other suggestions where to try?
