Oldies from archives: SYNOP reception!

It seems that I have recorded some videos about my early test with the system back in 2015. This time it was about SYNOP, those funny sounding HF transmissions that sounds like a morse code after some Quattro-Espresso’s.

Receiver (HW): RTL-SDR dongle, HamItUp converter, LongWire antenna, LNA4HFL LNA
Receiver (SW): SDR#
Decoder (SW): MultiPSK
