A couple weekends ago during the Ten-Ten International Digital QSO Party there was three DX stations I was able to contact that had 10-10 numbers. VE9DX, YV5MM, and LU1BJW. Four others who didn't have 10-10#'s, CO7WT, and VE3/N3XM, LU7HBK, and PP5OC.
Today, a few PSK31 stations are on K5FBS, KB1MGI, and W4ALE.
Also 18:18 UTC heard the VP of 10-10 WA2SUH calling CQ CQ CQ from his mobile in NY with a 59 signal on 28.390.
He heard my 70 watt dipole no problem for a short chat. To HOT to turn the AMP on, the conditions was good without it.
This Sporatic -E is always FUN on 10 meters.
