do you have 32bit?

[Cheerstoast]

No. I guess this is the problem :|

[Prograb]

Wait so I need to run my Pi 4 in 32 bit mode ?

[Cheerstoast]

@Prograb I use 64 bit, and I successfully get a ~20 meter radius on 88.0khz and a 10cm jumper wire, with software: https://github.com/markondej/fm_transmitter
