| Audio Sample | |
This data burst signal is fairly common on HFHigh Frequency (3-30 MHz). It has similarities to Link-11 and even SITOR-A, but is still different. Modulation is apparently FSKFrequency-Shift Keying with approximately 600 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). between tones and there is something on the edges of the signal. Bandwidth is something between 600 and 1900 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). depending on what is considered part of the signal.
If this really is a mode of Link-11, this sample can be added to the corresponding article.
