I just picked up a RTL-SDR dongle and I've been playing with various signals. I've also been a long time Eggtimer user.
I have working LCD receivers but I wanted to play around with using the SDR dongle to pick up and decode the signals from the HM-TRP transmitter on the Eggtimer modules. Maybe work on my own software to display live telemetry and GPS info.
I was able to use SDR++ and see the signal.
I've been trying to follow some of the other posts using rtl_fm ported to multimon_ng but I'm not decoding anything so obviously I'm not doing something right.
From what I can tell the transmitter uses FSK modulation.
Has anyone done this?
Can someone point me to any sources to help figure this stuff out?
Thanks!
