Hi Sebastian,
I must admit that I don't remember whether the TSB block base was
correctly wrapped for Python (darn it, first I write something, and
then you find a glaring counterexample); in fact, there's not a single
test case for that in the main GNU Radio tree, which probably means
"no".

That thing always confuses me, too. The "resampling ratio" is the

Also, I'd recommend not to rely on TCP sink/source, it's python-only
and it is indeed quite fiddly – the constructors can deadlock each
other.

Arbitrary counts, relative to what your Device and the attached DSP you
or the device are doing considers full scale.

No.
Hi Ellie,
which version of Redhat? What QT functionality are you missing?

Hi Francesco,
interesting!
Can you tell us how that memory leak manifests, maybe even whether you
can pinpoint the reason?
Best regards,

Hi Emmanuel,
my Apple experience limits itself to using an iPod in the summer 2010
or so, but I hope I can still be of help. First of all: Which path are

You've not install gr-smithchart successfully into the directory your
python looks into.

Hi Alex,
we do have two approaches for that
1. the XMLRPC thing, which is a python-world block that basically would
allow you to do the same you can do with e.g. a Qt GUI Range slider
(i.e. change Python variables at runtime)
2. Ctrlport and the thrift backend, the latter of which is notoriously
I'd recommend looking at the spectrum you receive. Also, how does
receiving a 20 MHz wide channel with a HackRF work? Wasn't the maximum
bandwidth of that lower?

Hi!
So, Occam's Razor first: Is it certain that gate_impl's general_work is
really called regularly?
Because: the message passing code here looks really good, and thus my
first guess is that of the code which you sensibly omitted here, the
rest of the general_work() somehow leads to the thing not
401 - 500 of 1135 matches
