ALT Close-up of a handheld amateur radio (Kenwood TH‑D75) showing a station list with “RSØISS” selected and the label “ARISS – International Space Station.” The display includes a compass graphic and navigation controls. Below the screen are keypad buttons labeled for APRS, VFO, tone, call, and other functions. To the right of the radio image, a blue graphic panel reads: “APRS: 70 CM Plans. Service Module Packet radio is operating on 437.825 MHz.” Additional text lists: frequency 437.825 MHz ± Doppler shift; path include ARISS; call sign RSØISS; mode FM 1200 BPS; beacon approximately once per minute; recommended transmit power 5 watts or less using a Yagi antenna. An ARISS globe logo appears at the bottom.
Wstrząsające… warkoczyki, buciki - relacja z ekshumacji w Ostrówkach z roku 2011. W trakcie prac ekshumacyjnych odnaleziono szczątki co najmniej 231 osób (głównie kobiet i dzieci), które zostały zamordowane przez oddziały Ukraińskiej Powstańczej Armii (UPA) 30 sierpnia 1943 roku.
To jest zabawne, dopóki sam nie czekasz na ten pociąg z 24-godzinnym opóźnieniem 🚆⏰😅 / That's funny until you're the one waiting for that train that's 24 hours late 🚆⏰😅 😉 @IntercityPkp@PKP_SA@PKPIntercityPDP@PKP_PLK_SA
