Hi All:
Here’s an esoteric request:
I am working on an Inmarsat decoder for 600 bps P-Channel frames. Gnuradio on
the front end, and a C program for decoding the recovered data frames. I’m
using an Ettus B200 for the reception and gnuradio as the demodulator. The
satellite is on 1545.110

Yeah, this is one of the things I like most about Dockerfiles... the self
documenting aspect. However... have you noticed how many times you end up
dealing with Docker images apart from their Dockerfiles? For a lot of
useful images, it's difficult (maybe impossible?) to track the Dockerfile

Does the start() function in GNURadio reinitialize the clocks on the USRPs
every time it is called? I have two USRPs connected via MIMO cable, so they
are synced, but my flowgraph calls start() after every loop, which I'm
realizing may be changing the constant but random offset of the clock every

Hey Geof -
I downloaded the any-arch installer and ran it on a SurfacePro4 Windows10
machine I have here, and it worked perfectly. I'm now using GRC and have
VOLK Profile running in the background, and everything is working
beautifully.
Thanks so much for taking the time to put this together - I
Hi Tom,
Thank you for your kind remind, I find the problem that I stored the metadata
file as inline type and I don’t need to add ‘.hdr’ with it.
Many Thanks,

I believe we have the PyBOMBS dependency issues sorted out, so if you
use pybombs (and e.g. 'pybombs rebuild') it will do stuff in the right
order.
Martin,
Is pybombs rebuild a pybombs2 thing? It doesn't seem to be a valid command in
the older pybombs.

Not a problem, glad to help. If you give my username edit access, I'll

Having almost no experience with Docker myself, I unfortunately don't have
much in the way of worthwhile technical input on this.
That said, I really do want to encourage this conversation. Installation of

many machines over

All,
Some may recall in the fall I posted a link to a beta windows installer.
I'm happy to report that I'm releasing new versions today for the 3.7.9.2
release, compatible with Windows 7/8/10. All dependencies are included,
and all are built natively using MSVC 2015, no Cygwin or MinGW required.
Hi Rob,
first feeling: make sure you've actually got enough RAM on your Pi; the
"VOLK: Error allocating memory" errors are kind of unusual.
Best regards,
Marcus

I'm really getting desparate.
The fact that your application generates 400B over-the-air packets has
*nothing* to do with the size of the sample packets going through
Ethernet. Stop assuming that.

You should not expect
61.44 MHz with the latest UHD stuff.

Hi,
I counted number of sending packet in code and wireshark.
I send 400Bytes packet, but wireshark packet be shown about 1500Bytes.
While coded counter shows about 50,000 packets (data packet), wireshark
captured 450,000 packets.
I expected one send() be represented one packet at wireshark.
While UDP gives no order guarantee, the USRP still sends them out in order.
The uncertainty comes in cases where routing happens between the USRP and
the host. Still, within a LAN you can expect with relative certainty, that
packets will still arrive in order, as there is usually only one route
29 matches
