[Discuss-gnuradio] Disable zooming on QT plotting widgets

2017-03-14 Thread Matthew Curlis
I am developing an embedded device that uses the frequency and waterfall QT plot widgets. Problem is my platform has a touchscreen without a right mouse button implemented - so I can zoom in but not zoom back out. I would just like to disable the zoom behaviour entirely. Can someone familiar with

Hi Andy, Dirk's problem was the low SNR in his recording, so he'd like to take the shape of his pulse into consideration, but he doesn't know the spectral position of the same – Dirk, can you confirm? Dirk, thinking about this, the relation of the spectral uncertainty to the bandwidth of the

If there is no information on the signal, why not just do a straight energy detector: source -> complex bandpass filter -> complex to mag -> burst/energy detector -> QT Time sink (triggering on start of burst tag) The complex bandpass filter just has to catch all the frequencies of interest.

Hi Martin, The aim is to check for the existence of a 10ms pulse in the incoming radio signal (from an sdr). The thing is I only know the frequency of the pulse to within ~1khz. So a single filter in my case is: generate a synthetic pulse (complex sin wave) of the same length and with a
