The topic of "what kinds of questions go on gnuradio-discuss" has come up a
couple of times over the last few weeks, and we've had a lot of fresh
subscriptions over the same period (I get all the subscribe / unsub
notices), so I'll take this opportunity to quickly answer the question.
What Marcus a
It was definitely part of the fundamentals I wanted to finish up before
getting out there next week. A long-term goal is being able to point an
antenna at lunar or Mars sources (obviously Lunar being a little more
achievable from a "back yard" antenna). Skytrack now gives me the ability
to contro

Hey Mike -
Whoa, this is cool - thanks so much for sharing it!
It sounds like you wrote it principally to facilitate something of a soft
hand-off between two receivers positioned around an occlusion, but do you
have thoughts on the utility of expanding it past receiver diversity?
Thinking through

Hey Moses -
I don't have an immediate answer for you, but it seems likely the issue is
with `decoded_u8`. Before spending time trying to debug why this might be
happening when the code is used in GNU Radio versus not, it would be good
to figure out where exactly the leak is occurring.
You should

Every instance of a block is an instance of the c++ class but like Nick
says all your variables are static and not member variables. Those need to
be declared in the header. Your two block instances are referring to the
same variables and that's why things get messed up.
"A tour of C++" by Bjarne
It looks like you've declared a bunch of static variables within your
block's namespace. Those variables (including pointers!) will be shared
with every instance of your block. This is Bad News. Those variables should
probably all be declared in the header as class member variables.

I'm running into a strange issue with a new flow graph [1] I'm working on
that uses a custom C++ block [2] that I built. The block takes input
samples, performs some DSP, and outputs modified samples at the same sample
rate.
When the flowgraph has a single instance of my custom block enabled, it

HI everyone, another new tracking module that now integrates with GNURadio
I just released here:
https://github.com/ghostop14/skytrack
Skytrack takes signal tracking out past gpredict with earth-based
satellites and allows tracking (doppler frequency shifts and azimuth and
elevation) out to solar
That is a very generic problem: Programs from your docker container
can't connect to the host's X server. Google that error – there's
plenty of articles on how to make X programs work within a docker
container.
Again, I'd strongly advise you to use something less ancient than
Ubuntu 16.04.

Hi, and thanks a lot for your reply,
please find below two of the errors I am getting:
1- dpsk_loopback.py example used and I got:
*dpsk_loopback.py: cannot connect to X server*
2- I used one of the modified codes that uses gr-ieee802.11 I got something
like
*File "/wifi_rx.py", line 79,
Since the whole purpose of using a docker container is to isolate the
contents of the container:
Please use something less ancient than Ubuntu 16.04.
Best regards,
Marcus Müller
PS: "I get errors" is probably not a sufficient description to help you
in any way! Please be more verbose :)
