I think the general idea is that some signals have no carrier that a PLL
could lock onto. The FLL Band-Edge centers a signal using the shape of a
specific signal (the matched filter being used).

Hi Criss,
Unfortunately it seems there is no easy solution to this problem. But at
least I can go back to Ubuntu18 which installs gnuradio 3.7 and I can
still use my old codes.

Hi all,
I have been reading some more on PSK demodulation.
One of the PSK signals I can easily pick and and is available 24h/day is
the telemetry signal on QO100.
I found a flowgraph from Daniel Estevez that decodes the QO100
telemetry, so I started examining how it works.
In that

You don't have MPIR - you have MPLIB instead. It's not a bug.

Hi Tim,
Thank you very much!
I followed your suggestions and have it working, I put v.self in the def

vector parameters at start-of-program by placing them in the def __init()

George,
What is happening is that when you try to change the variable Python is
interpreting that as a local variable and has no value yet for the equation you
are attempting. I believe could use:
global vv[0] += v[0]
(Research the Python global keyword)
However, in the GNURadio universe I

Problem, so when I make v global in my_init() method and use it is the
work() method, it works good if I do not try to change the values in the
vector v, let's say v came down as v = np.array([1.0 , 1.0 , 1.0]). If I
try to change the values say v[0] += v[0], etc. the program

Hi Tim and Jeff,
Thanks for your help and insights. Being new to Python, I was looking at
some Python videos and found my solution, I will make the numpy parameter
vectors in the my_init() method "global" and that should solve the problem.
Thank you!

Hi Jeff,
So I am new to Python programming, so some of the nuances I am not up on
yet. My understanding is the self.x, etc. is used to initialize param
arguments in the def __init__() method and in my case, the only argument in
this method is start, there is no v for me to use self.v = v. v is
You are already initializing self.start in exactly the same way you should
be initializing self.v, right?
