GRC Blocks #8

Open HalfDeadPie opened 5 years ago

HalfDeadPie commented 5 years ago

Hello,

I would like to ask you, if you've tried to implement receiving using GNURadio Companion blocks. I'm trying to use a different tools (scapy-radio), however its blocks are only for 40Kbps|FSK|NRZ. I'm trying to implement blocks for 9.6Kbps|FSK|Manchester and 100Kbps|GFSK|NRZ. Honestly, I'm stuck.

I never tried in gnu radio. But as I remember 9.6 has an offset of 20khz to one of the sides. The frequency derivation in 100kbit is 58khz I think. Your receive bandwidth should be at least 150khz, at the spec allows the transmitter to be 75khz off because of temperature drift.

Good luck 😀
