Also, there's no reason to lock the flow-graph for frequency changes or gain
changes (or a bunch of other parametric changes
within the flow-graph). I've never had to use lock()/unlock()--I
understand that they're used during flow-graph topology changes.
But parametric changes don't

Dear all
i have a usrp1, RFX2400 and WBX and i have a coaxial cable from the wifi
card to the rfx2400 TX/RX port
i want to pass the stream from the wifi card to the rfx2400 then to the wbx
to transmit it over the UHF band
how could i do that ??
here is the connection i have created (attached)

Hello,
I would like to ask if someone could tell me how much of the USRP2's FPGA
resources are consumed by the firmware (the ZPU) and the FPGA (DSP
operations) images. Or, in other words, how much of the resources is free.
Thanks!
Edu.

Hi Ryan,
What version of GNU Radio are you using? I'm working with the USRP2 to
collect GPS data and I have a similar scheme: I have a cyclic buffer that
holds data that was recorded just prior to a triggering event. Once a
trigger event is received, incoming data is written to an open file

Hi,
I am new to both gnuradio and spread spectrum. I know I'll eventually have
to move to writing python, but I am trying to get something working in grc.
My question is about the PN Correlator block. I would like to generate some
transmit data that is coded using the same reference pn codes

hi.
i wanted to simulate a transceiver which receives some data and then
transmits its own and the data it got.
I have been modifying then benchmark_tx and rx program to do this and
I was able to simulate the transceiver I mentioned, by adding the
sender code in the def_rxcallback function.
I dont

Yea, sorry for vague email. Was tired and in a hurry. I encountered the

Try using a single pole IIR filter. If you don't know what an IIR is, wiki
it, better explanation there than from me. Keep pushing the frequency cutoff
to a lower frequency until the static gets better. If you go to far, your

Quick question: why is the removal of support for the USRP2 (et. al.) being
contemplated? I know its a bit older, but is there another reason?

Nothing to do with age. It has a lot of problems and isnt feature
complete.

Support for USRP2 is not going away in GNU Radio. Instead, we are

Hello list,
I have pulled work from the next branch into the master. If you are
working from the code in the master branch, you will need to update your
FPGA images. In the case of E100 users, this will also require a kernel
uImage and kernel modules update.
