NotPike Posted June 18, 2017 Posted June 18, 2017 (edited) If you want to replay the signal you'll need to record the IQ data. Which SDR are you using? This video might answer your question too. https://greatscottgadgets.com/sdr/11/ Edited June 18, 2017 by NotPike Quote
bend Posted June 18, 2017 Author Posted June 18, 2017 hi thanks for your answer. For the moment i am using GQRX and DVB-T+FM+DAB 820T2 & SDR. I know that i can't replay with that USB Key but it was just to have a look My Heater is using 434,33Mhz. i want to replay the signal with a raspberry pi do you know: What software is able to record IQ data on pi? What hardware do i need on the pi to replay my IQ Data at 434,33 ? Thanks for your help If you wish i can provide you the wav signal?. Regards Quote
NotPike Posted June 18, 2017 Posted June 18, 2017 (edited) Yah please do! I use osmocom_fft when I recorded raw IQ data and use inspection to view the signal. Inspection is a good tool because it can measure the simble rate. I would check out the HackRF and the YSO. Edited June 18, 2017 by NotPike Quote
