Hello All, I'm still having trouble transmitting from file, a car door clicker waveform that I saved, similar to one of the tutorial videos.
For one thing, the TX light comes on when I start the flowgraph, but when I close it, the light stays on. Is that normal? And, generally speaking, what are things to look for when debugging TX problems? I can think of two problems: I'm not transmitting with enough power, or I messed up the waveform somehow when I recorded it. Regarding the first, I've tried setting the RF gain as high as it will go, and I've tried different antenna lengths. Regarding the second, I'm worried that I may have saturated HackRF when I recorded the waveform. Is there a way to tell, if I view the recorded waveform in the QT GUI time domain plot? Anything above 1 V or below -1 V? I guess the waveform would look clipped, but it appears so quickly, that it is hard to tell. Same question on transmit: how can I tell if I am saturating? I'm also aware of the trick in the video about multiplying by a constant to increase SNR. Any other ideas?
