Thanks for the tip.
I did 1 and 2 (but didn't find a gr-digital map in the examples on
GRC software), and what do you mean with: "it's misconfigured".
Also you say that OFDM would be interesting(It normally would) but
because of some circumstances I can't use OFDM. It is because its
frequency spectrum is to low (1.25MHz to 20MHz). But the frequency
spectrum that I am later gonna use is from 300 MHz to 3.8GHz (because
I am gonna use a bladeRFx115 eventually as the HW component).
Best regards,
Quenten

Hi Quenten,
you're using multiple deprecated blocks; especially the packet
encooder/decoder are simply buggy and drop data. (Also, it's
misconfigured, but properly configuring it won't help. Don't use it.)
Also, while your computer might be too slow, the Throttle guarantees
that the UDP source has to drop UDP packets if your data rate is
higher
than 500 kB/s...
So,
1. Replace deprecated WX GUI with Qt GUI
2. Remove all throttles
3. replace packet encoder/decoder with appropriate packet
transmission
example from gr-digital
You'll notice that a video stream is a lot of data, and that 500 kHz
bandwidth simply won't do with GMSK to transport that amount of data.
Which means you'll need more bandwidth. Which means you'll see a
frequency-selective channel. Which means you need some
equalization, or
a multicarrier scheme! The OFDM-examples in gr-digital will be of
most
interest to you.
Best regards,
Marcus
