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

Hello,
I am Kartik Patel, undergraduate student from Indian Institute of Technology
Roorkee. I am interested in the project A web based GUI for GNU Radio.
Here[1] is the first draft of my proposal for the project. I have tried to cover
the background, the output as well as the flow of

Dear All,
I would like to control the variables in realtime of a GNU Radio Flowgraph
(like Sampling Rate, Center Frequency, Demodulator type etc.) from a Webpage
or external application.
I imagine that we need a webserver/ external application that communicates
with the Flowgraph.

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
10 matches
