| Audio Sample | |
This signal was transmitted on the marine band on 16807 kHzKiloHertz (kHz) 10^3 Hz. It seemed to have MFSKMultiple Frequency Shift-Keying with possibly irregular tone spacing. Spectrum was somewhat dirty with multiple side tones. Then it changed mode to narrower (M)FSKFrequency-Shift Keying and finally to very narrow FSKFrequency-Shift Keying or wiggling carrier.
Samples[edit]
Wider tuning to include the first "side tones":| Mode 2 (narrower MFSKMultiple Frequency Shift-Keying) and 3 | Mode 3 (very narrow FSKFrequency-Shift Keying/carrier) |
