2025-06-21 07:00 UTC – Photo received from the 🇷🇺 🛰️ RTU MIREA1 (RS51S) on 436.203 MHz, in GMSK 9600 bd. Sadly, the satellite transmits only over the Russian territory and the tx frequency is drifting. Rx with Airspy R2/Mini R2 and Yagi antenna in 🇬🇷.

2025-06-21 07:02 UTC – Partially received photo from the 🇷🇺 🛰️ RTU MIREA1 (RS51S) on 436.203 MHz, in GMSK 9600 bd. Unfortunately, I was unable to recover at least the first not decoded packet from the IQ recording. Rx with Airspy R2/Mini Mini and turnstile antenna + LNA/BPF in 🇬🇷.

Never give-up! 😀

Landing prediction of the EMY radiosonde that will be released on June 22 from Thessaloniki Makedonia airport (LGTS), 🇬🇷. Only a few meters away from the release site! 😲 I fiddled a bit with the burst altitude (added 400 m), but who knows exactly? 😆 Theodoros Kolydas
