CIS NAVY 50 Bd and 100 Bd FSK BROADCAST SYSTEM

(A.K.A BEE or 36-50)

FFT-SPECTRA 

---

The FFT-spectra of stations using the CIS Navy broadcast mode depend very much on the shift, the degree ofdistortion on
the signal and the bit pattern being sent across the circuit, so there is no typical FFT-spectrum for these stations. Here are
however FFT-spectra of the two most common baudrate shift combinations that are being used by the various CIS-NAVY outlets:

• 50 Bd / 200 Hz

 

• 50 Bd / 250 Hz
