ASRTU-1 SSDV images live-decoder on Linux


● (No.1177) ASRTU-1 SSDV images live-decoder on Linux (2025年12月21日)
 ---------------------------------------------------------------------

gnuradio-companion (旧)Ver3.7上では、そもそも asrtu_1.grc が開かなかったので、
Linux用radioconda を使い下記の手順を行ったところ、gnuradio-companion Ver3.10 
自動的にバージョンアップしており、その上では asrtu_1.grc は開いたので、続けて
Wine上で ASRTU-1-EN.exe を起動した。しかし、asrtu_1.grc は開いただけで実際は
稼働していない。現在原因究明中。(ASRTU_1.py と連携がうまくいっていないようだ)
