From 
Video, where sporadic 144MHz from 25.5.2020 is captured, as TA7OM hears it from the KN80XX locator. I also did it and many other hams from OM, e.g. also Milan OM5KM, OM3CQF, OM3TIX.... The distance from me is 1767 km. I used TCVR IC910H, mal som výkon necelých 50W a anténu iba 2ele yagi na ráme kuchynského okna.
