Hi everyone, I've enjoyed analogue scanning for many many years but now moving into digital with the SDS100 and also playing with the RTL-SDR and several apps.
I'm really curious about all the "digital" tones received when listening using analogue mode and scanning across frequencies.
Is there any way to identify what system each transmission is using, and then perhaps decode them too ?
I've enabled P25 and DMR on the SDS100 so can decode them, but what could all the other tones be ? (Sorry I don't have a recorded examples so they would be difficult to explain)
I have tuned DSD+ with the RTL-SDR which has a few decoders but they don't recognise most of the digital transmissions I find.
I am also guessing they could be propriety systems like the hand-held screens used by couriers, taxis, electricity co, etc etc etc.
Does anyone have any tricks or resources to better understand the various "digital" transmissions out there ?
Thanks heaps.
