Stream DAB+ ensemble to a plutosdr clone with proper firmware to modulate it transparently. Received with #rtlsdr. Opensource rocks ! github.com/Opendigitalr...

Hope to meet you in few days at fosdem.org/2026/schedul... Talk about #plutosdr clones and firmware.

Tweaking hdl to sync sweepfft...seems coherent, but wide rx involved 3rd/5th harmonic caused by square LO. Look for a low cost digital controlled Low Path Filter to avoid this, any idea ? This is 480 Mhz span, from 80-560 Mhz at 50 fps

Proof of concept for sweepfft (480Mhz span) using plutosdr and modified maia-sdr hdl design. Still some work to do for interface, but hope a good start.

WebSDR at 47Mhz bandwidth experiment (FM broadcast and aero band) using antsdr e200 with CS12->CS8. This time with rounding to avoid big DC ! qra.f5oeo.fr:9002
