The staggering of the imaginary part in combination with the half sine
pulse shape, makes the constellation point move on the unit circle.
During a bit period it makes a 90 degree transition to one of the
neighboring constellations (encoding the 0 and 1). It doesn't actually
stay at the ideal c
Hi,
I recommend to start with the example flow graph and make sure that it
works works for you. If that works, just replace the constant message
source with the data that you want to transmit.
Did you maybe delete the packet pad block and just sent data back to
back without any space in betwee
Thank you Marcus!

Hmmm. I took a look at your signal and trie
Thanks.
Using the FCC Id of either MLLSPEEDHPTX450 or MLLSPEEDTXP45-47 - they
both have the same IC - then from the RF emissions code, i.e., 7K10F1D,
the 7K10 indicates it has a maximum bandwidth of 7.1 kHz, the F
indicates is FM - but the documents on file indicate it's 2FSK, the 1
indicates on-o

I'm not sure. Maybe it was related to one of the Packet Pad blocks.
Since you resampled, you also changed the length of

I have another related question about the wireshark connector in

Hi all,
I am in a situation where I have a grc flowgraph set to 'NoGUI' mode with
no GUI blocks. I use this to auto-generate python code that is then called
by other python code.
One of the machines I'm working on does support GUIs, everything is through
the terminal, so I can't open grc files. I
