RBN map of HF spots |
The ARRL Letter says RBN managers cited the sheer quantity of FT8 spots in relation to other modes, noting that on May 23 and 24, more than 85% of all RBN spots originated with FT8 stations. The announcement said it was unclear whether this was the result of the digital mode's exploding popularity or the fact that it can spot stations 22 dB below the noise. At press time, the separate FT8 spot feed was still being beta tested.
