@IberiaDX @RadioHacking Hola,
Por si te interesa la recepción de un CIS-12, tenemos uno transmitiendo desde esta mañana en la banda de #radioaficionados de 20 m, en 14005 kHz CF (14003 kHz USB), actualmente en frecuencia (1649 UTC).
BW = 2.7 kHz. 12 X 120 Bd + tono piloto
Saludos!
#IARUMS
#RFID interrogators radio signals: 4 channels ( 4,7,10,13 ) in the lower band 865 to 868 MHz, 200 kHz bandwidth, 600 kHz channel spacing. Interrogators shall communicate using DSB-ASK, SSB-ASK, or PR-ASK modulation 🧐📻
Yet another 75Bd (actual 50)/850 FSK bearing KW-46 encrypted broadcast spotted on 5189.50 KHz (CF), this time from France (likely Sainte Assise, near Paris).
The reason of that "bizzarre" format is still unclear (atleast) to me.

An interesting signal for HF is OFDM-319 channels, BW = 12kHz (hybrid modem + mFSK mode). Made in Russia. The modem can use up to 40 kHz bandwidth.
