So, it seems like no official place exists yet.
Some things are mentioned in the issues on github, but they don't contain very
much information at the moment.
So, to summarize what I found out so far:

Hello,
I recently acquired an XTRX SDR from crowdsupply, and now have new hardware to
play with.
However, I find myself with some lack of documentation for the new hardware and
also cannot find a public place for discussions about this particular hardware.
I was wondering whether there are
There exists a small utility function for this purpose in the gnuradio
sources.
It can be found here:

Either use it directly, or as an example how to do it.

Offset is a DC offset here.
I probably would use a "Skip Head" block to skip the right number of samples to
get the correct initial phase. Although the setting for that block depends on
the frequency and the sampling rate.
Or if we're talking about complex values, a "Multiply const" block would
Hi,
Does this GRC hierarchical block solve your problem?

My experience has been that letter suffixes are only used for displaying
values, and not for entering values. Are you sure the examples used that
notation to enter values?

Hello,
as far as I can see, the low pass filter block only exists in GRC.
The relevant XML description for GRC can be found here:
https://github.com/gnuradio/gnuradio/blob/master/gr-filter/grc/variable_low_pass_filter_taps.xml
The underlying source for firdes can be found here:
Hello,
I noticed that the fastnoise_source block is not thread safe, as it
calls rand(), which keeps global state.
This makes it non-reproducable between multiple runs once more than one
such source is used.
I also opened an issue about this on github:

Hello,
I was wondering, whether it's possible to write a hierarchical block
that does not have a fixed number of inputs.
Of course I can specify the io_signature appropriately.
But it seems like the only way to determine the number of actual
connected inputs is to look at the parameters that are
Hello,
I have the following problem:
I wrote a block that does some processing and needs to look ahead in the
data for a certain amount.
Therefore the work function of the sync_block will return 0 if the
current amount of data is insufficient.
This works fine if the program is running

Hello,
I am trying to write a block that produces a different amount of output
depending on the tags.
For that I would need to access the tags in the forecast function. Would it be
safe to do that?
Or can the tags still change in between the call to forecast and the call to
general_work?
