Thank you for reading this.
I have one last error to overcome:
Error 0:
Block - gr_freq_xlating_fir_filter_xxx_0 - Frequency Xlating FIR
Filter(gr_freq_xlating_fir_filter_xxx):
Sink - in(0):
Port is not connected.
Can anyone offer a suggestion that will sort this out?

Hi,
I have a couple of questions about the print out of the overrun and
underun indications.
Is it possible to turn off the output of those indications?
And second is gnuradio doing anything with stdout that would affect
redirecting stdout?
This is the text output I normally see in a shell win
Hi,
I'm working on a modulator using a punctured (non-recursive) convolutional
coder based on a 1/2 rate mother code with length 7.
However I find the documentation of gr-trellis pretty hard to read, I don't
really understand how punctuation should actually be implemented.
Are there any additi
Each XCVR2450 is already locked to the motherboard crystal. But "bypass it
with the motherboard's
X-TAL source" does not make sense. The LO is generated by locking to the
motherboard crystal source. No bypassing is necessary.

Hello,
we have a USRP1 with 2 XCVR2450 daughtercards. Each XCVR2450 has its
own LO however , we would like to bypass it with the motherboard's
X-TAL source.
Both XCVR2450 daughtercards will then be driven synchronously by the
motherboard.
Is this possible ? If so, is there a schematic of the
Greetings,
Is there a smart way to delete a GNU Radio block in C++?
Until now I have been using the shared_ptr().reset() method but it
seems to me that it will only call the destructor if the parent
top_block has not been run.
This gives me problems when I try to delete and recreate a hardware

Hi Community , some more video are up !!
I have shown how to start working with gnuradio-companion. There are 4
screen casts. Very introductory for the new comers :)
connecting the blocks, data types, putting multiple windows in tabs, etc I
have shown. Suggestions and feedbacks are very welcom

Hi Tom & Nick,
Thanks for your replies. The function generator is producing a sine wave
with 1 V (10 MHz). This is going to the ref clocks. The E light is ON and I
have changed the clock source option to be external in gnuradio-companion
environment. I tried with square wave, too. But the output d
Hi,
We are using USRP1 to build a RFID reader which operates on 915MHz
frequency. The RF daughterboard used is RFX 900. Currently the power issued
by the daughterboard is too small, only 200mW. Can we increase the output
power by connecting daughterboard with a signal amplifier? We want to

Hi,
Does Gnuradio provide a possibility to measure a net data rate of a TCP source?
I would like to output how many packets (or bits) per second are being
successfully received in my top_block.
Thanks
