Swan taxi data channels

Post by macca1024 »

Hello all
I've been scanning around the band on my SDR and came across a data transmission from Swan taxis. I assume it's for those in car units they use. Has anyone written a decoder for it or aware of who makes the equipment or any docs on the signal standard? Thanks.

Sounds like it, to me it looks like some sort of high speed FSK. The low-high transition could be for frame sync.
