So why not get help from SignalID?
At the moment, it recognizes about twenty signals (the exhaustive list is below)
With only 5 seconds of recording time, it tries to recognize the signal.
To use it:
Set the frequency and bandwidth properly.
Selecting the frequency range. (0-30 MHz / Other)
Place the microphone of the telephone near the loudspeaker. (The quieter the environment is around, the fewer errors will occur)
Press the big button that dances.
Wait 5 seconds. (Time required for the record)
The algorithm is based on frequency, a wrong tuning of your radio/SDR will result in an erroneous detection.
The recording is limited to 5 seconds, for practical reasons. Recognition of a signal may require several attempts.
If you notice bugs, have remarks or suggestions, please leave a comment.
Here is the non-exhaustive list of recognized signals :
– RTTY (Commercial 85Hz, 170Hz, 450Hz, 850Hz, Amateur 170Hz)
– PactorI (Standard, FSP, FEC, SELCALL)
– ASCII (170Hz)
– Codan8580 (200Hz, 250Hz)
– STANAG 4285 (GEN, SYS3000 FEC, 8PSK, TFC, IDLE, SYS3000)
– WEFAX (120, 240)
– 2G ALE
– 3G ALE
– APRS (Burst)
And more! Complete list in the application.
– FLEX (2FSK)
– PSK (31, 63, 125, 250, 500)
