Talk:Unknown 449p936

This is a very popular signal standard in the EU and in canada that uses an unusual set of AFSKAudio Frequency-Shift Keying.

Characteristics: 8 bit ASCII FMFrequency Modulation 2FSK (colloquially as "AFSKAudio Frequency-Shift Keying"). 600 bits per second with 900 hz Mark and 1500 hz space frequencies (1 and 0s). Sorcerer used to be able to decode these signals very easily and was literally the tool that was used to decode this stuff for the EMWIN page...(except it was actually a different set of afsk tones).

I am able to simulate this exact signal in audacity with teejeez's SDR IQQuadrature signals form the basis of complex RF signal modulation and demodulation, both in hardware and in software, as well as in complex signal analysis. modulate plugins. Here was the result: I even made the second clip distorted as some give off that characteristic... Yalek W (talk)
