Established radio communication in FT8 with a radio station **R0UO**, from square OO90 - Russian Federation, Far East near China. The distance between is almost **5300** km, the propagation of radio waves did not occur without a double jump. I received -19 dB, and I received -8 dB. QSB from -10 to -20 dB was noticeable. `R0UO OO90 FT8 -19 -08 20220312 073215 20220312 073315 17m 18.101664 RA1AHQ KO59CT 10 ` Then, in the 21 MHz range, he made radio contact with **RZ0SW** from a square **OO13**- distance 4300 km. I received at +2 dB, I was heard at -15 dB. `RZ0SW OO13 FT8 +02 -15 20220312 074145 20220312 074245 15m 21.075062 RA1AHQ KO59CT 10 ` Power 50 W, GP antenna - fishing rod from the balcony. Of course, in SSB you can't hear distant stations as confidently as in digital. --- The distance is calculated in the program **QTH Locator Toolkit** for Android: [Download "QTH Locator toolkit" from https://play.google.com/](https://play.google.com/store/search?q=Qth%2Blocator%2Btoolkit) --- P.S.
