Title: Polish F11 number station FSK decode at 7837 kHz (two transmissions)
Post by: Strange Beacons on May 15, 2017, 0530 UTC

Polish F11 number station FSK decode at 7837 kHz (two transmissions).

Both transmissions occurred at the same frequency, 10 minutes apart. This was decoded using the Rivet b88 decoder, set on the FSK raw mode at 100 baud with a shift of 625 kHz.

I've been wondering, is the decode that I made in my video in binary code? And if yes, is your post above a translation of the binary code?

The transmissions are in FSK 100Bd/620Hz shift. I decoded it myself on the 15th

So my settings were incorrect...

Thanks.
