Hi everybody,,I'm
I
am working on a larger project, a "remote" transceiver for satellite
traffic, trying to limit the need for bandwidth via Internet since the
remote location does not have enough bandwidth available.To
further reduce bandwidth consumption and to have a spectral
representation I do not send the IQ stream to the control terminal, but
only the vectors obtained from the FFT; so I went from about 20Mb/s to
500kb/s, I would say more than acceptable!
In the
control terminal, however, I have the need to "return" the "point and
click" frequency indication to the remote side. This works correctly on
the QT GUI Vector Sink ( spectral representation ), which has an MSG
port but, from an operational point of view, it would be better to be
able to have the same functionality via the QT GUI Time Raster Sink (
waterfall representation ) block, which does not have an MSG port
available, even if the Xval value it's there.
I
realize that this is not a "real problem" but just a missing feature
that I hope can be implemented in the future ( I'm not so skilled to do
it myself ;-) )
In the meantime, I continue to have fun with this project!
Thank you for your attention, maybe someone can suggest me some other solution.
