Hi Tapiwa,
There should be object code for fixing the B100 USB interface in the UHD
tree under /host/build/utils.
cmake compiled it for you when you built the whole UHD.
The bin file to use is fx2_init_eeprom.
Use the --help option to get usage info.
You also need the suitable b100_boot.bin and

No. But you can produce 8-bit sample
mpuational cost can be further reduced.
Of course, not comparable to the power efficiency of an ASIC. Yet.

hi everybody,
I'd like to know how I can convert a GNURadio .dat sample stream into a
format which I can handle through matlab or octave.
Also I'd really like to be able to set explicitly the number of bits
used to represent samples, from within a Python script, in order to
afford higher sampling
thanks Eric, thanks Lee.
octave import function worked straightforward, and was actually very
useful.
I still have some doubts about the 8bit samples.
I have tried the usrp_fft.py, but when I do require 8bit samples through
the provided command line option, the fft sink displays nothing at all,

Hi,
I think I got the point , I was doing twice the same thing.
It was not clear to me that symbol demodulation is already included in
viterbi block.
so now I've got the convolutional code working, and would like to add
interleaving and an outer Reed-Solomon block encoder.
can somebody show me
Hi Achilleas,
yes.. I had got a bit confused about how to use these blocks...
is this correct instead?
Nfft=2048
file_source_bytewise=gr.file_source(gr.sizeof_char,
"/mnt/root/gnuradio_datastreams/1.MPG")
file_chunker=gr.packed_to_unpacked_bb(1,gr.GR_LSB_FIRST
Hi Matt,
could you please detail to me the modification needed to use the
following feature of the RFX400
quote:
"
Additionally, minor modifications to the board can move
receive ports.the frequency range to anywhere from 200 MHz to
800 MHz (contact Ettus Research for details).
"
we could b
thanks Brian.

just a quick question, I need to tell the constructor of my first gr block
to accept a bit by bit input..
I should call sizeof( what? )
thanks
sorry for bothering for such a trivial thing but I haven't found an example
of this yet..

..How could I test a non real time transmitter? (I think I
understand not real time receiver but how did you test the
transmitter?)

hi everybody,
sorry for bothering, but I haven't managed to solve this:
whenever i try to declare an array of any kind I get this:
expected unqualified-id before '[' token
as an error message which prevents me from compiling my block
is this known already?
best regards

Hi everybody,
I'd like to know whether there are any new upcoming devices from ettus
research, able to transmit anywhere within [470,870] MHz.
and, if so, when they'll be available (more or less) :) .
best regards

hi list,
could anyone send me a link for me to see the right syntax that should
be used in python to connect a block with N output streams to one with N
input streams?
is it just a connect(a,b) ?
thanks
