Well done.   And it gets better -

Decoded at Bielefeld distance 303.8km via DL4YHF's online
receiver.

Copied 'ULF' at Eb/N0 =3D +2.4 dB constant reference phase.
BER 36.7%, carrier 14.7 dB in 34.7 uHz,  -63.9dB in 2.5kHz.

There was one timing glitch - a backward step of one sample
but it decoded without having to adjust for this.

I will look at Cumiana now!
