#PopoSDR - Twitter Hashtag

LoL I was trying to debug the socket sink/source of my SDR library "thing" and made a working FM demodulator (again).... Might be a good time to commit these changes.... SDR++ IQ Exporter -UDP-> C++ fm demod -UDP-> FFplay #sdr #cpp #sdrpp #rf #iq #dsp #poposdr

Oh, network sink + network source will help a lot with my project thing #PopoSDR !

Just finished the SDR++ Network Source. With it you can trivially import baseband live from any software that can output IQ to network. For this demo, I use #GNUradio to generate a FM signal and send it over TCP to SDR++. It is now available in the latest nightly. #sdr #sdrpp

(WIP) Demodulating real QPSK packets using #PopoSDR ! Timing & Phase Sync. Working! Tx: #Python TCP pktgen -> APSKModem (PopoSDR) -> TCP socket to #GnuRadio (fwd iq)-> #PlutoSDR Rx: #RTLSDR -> #SDRPP -> APSKModem (PopoSDR) -> TCP socket to #GnuRadio (fwd iq & gui)

Oh... QPSK demod works... Still needs one Frequency synchronizer (Band edge FLL pehaps?).... #PopoSDR #SDR #RF #DSP

So... The timing recovery block from #PopoSDR seems to be working (finally...) Using a Matched RRC 0.5 Filter Bank with 32 arms and ML-Ted... #sdr #dsp #qam #rf #16qam #rrc
