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.

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

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.
