FAV22 conspiracy theories. Do spy stations publish their transmission schedule and content?.Have they been sending the same messages every week for many years?.Do they send QSL cards?.Here is the lesson you heard and 2 QSL cards I received 10 years ago. ๐Ÿ˜‰

๐Ÿ‡ซ๐Ÿ‡ทFrench do it better. They claim to have a station, FAV22, broadcasting on TWO ๐Ÿ˜ณ HF frequencies, 24/7, to train military radio operators in Morse code. ๐Ÿค”.In my opinion, they actually send ciphered messages, like ๐Ÿ‡ฎ๐Ÿ‡ฑ4XZ, Numbers Stations, and similar. ๐Ÿ“น: ๐Ÿ‡ฎ๐Ÿ‡นMilan 21:49z July9

SSTV fans: stay tuned for mid-July activities! . It's an appropriate collaboration between ARISS Russia and USA as we celebrate the Apollo-Soyuz Test Project. Also, it's been 40 years since SSTV in human spaceflight, so we'll celebrate STS-51F as well.
