Hello,
in the program I am currently working on, I sometimes get the following error
messsage:
python: gri_mmse_fir_interpolator_cc.cc:66: gr_complex
gri_mmse_fir_interpolator_cc::interpolate(const gr_complex*, float):

It seems like the assert
Hi guys ,
I am using DBSRX , now i am trying to trace the data flow in the
usr-gnuradio . I see AD9862 ADC in the usrp and some of the block diagrams
, and i think that the daughterboard
passes the analog signals to the ADC in the I and Q format . Please guide me
if this is right or wrong ...

Hi,
I try to add all it needs to put my custom block into this module. I add
the corresponding .xml/.cc/.h/.i files into grc/lib/swig folder

still cannot work. When generating top_block.py in GRC, the console

Hello~
I am trying to implement a relay system.
The relay system that I am trying includes 2 TX and 1 RX.
And 2 TX must transmit a signal synchronously.
Now, I have only one USRP2. So I am planning to purchase one of the USRP
series.
My original plan was buying one USRP2.
But I saw t
Hi all.
I need to use external clock on usrp, there are two kinds of clock: sine
wave and square wave. which
is better for usrp?

Dave,
To bypass this problem, change the pkt.py file. In the end, after
msg = self.rcvd_pktq.delete_head()
add
if (string_len > 18) & (string_len < 4096) :
ok, payload = packet_utils.unmake_packet(msg.to_string(),
int(msg.arg1()))

No I am using TVRX to receive and basic TX to transmit. I have changed the
following values,
Receive.
Decimation=256
gain = 20
Transmitter.
Interpolation= 512
Multiply Const=5000
I am now receiving my audio file and saving the data into another file.
Though the data is not the just the file da

Josh,
Two issues in GNU Radio companion.
I'm working on a hier_block in GRC and want it to have multiple outputs.
When I generate the block, though, I get a few problems. First, only one
output pad is exposed. Looking at the generated XML file, I see that only
one source block is being created (I
Hi folks,
Firstly, thanks very much for your response Nick - you've answered my
main question on how to recover a completely bricked N210 in future.
There are two reasons why I'm hesitant to blame UHD: I ran the update
while I was (accidentally but foolishly!) streaming data from the
USRP, albeit
I've recently been using tunnel.py for 1/2 hr tests with no problems. I'm
using the basic_tx/rx boards with a low frequency (5 MHz) and 1 Mbit
datarate.

I am working with two USRPS wired connection with 25 dB attenuator between them
so I didnt expect to much corruption of the packets.
The error seems to occur quicker at lower bit rates for some reason , like
around after 10s of minutes for below 250 kbps and more like after an hour or
more for
