Yeah, I got it. I read in a tutorial and I understand now.
Thanks again.

Hello,I have built a Multi band NBFMtransmitter.As I increase the number of
channels for transmission ,the noise is increasing.How do i counteract this in
the code.The code is given below#!/usr/bin/env python## a program to send
multiple mp3 playlist on the FM band#in this example a single mp3

With the RFX2400, and most of the high frequency usrp daughtercards,
there is no IF frequency. The samples you receive (or send) from the
usrp.source_x

If you only needed one daughtercard this would be very do-able, we
looked into leaving off

The LFRX and LFTX. You may need external filters and/or amps
depending on your application.

Hi,
I want to use gnuradio and USRP for 1.6MHz to 30MHz, is it possible?
If so, what daughterboard should I be using for USRP?
The other question I have is whether it is possible to have a
mini-usrp board that can be moulded into a somewhat handheld device
size?
Regards,
Woody
no I don't understand this either.

Hi,
If I am using RFX2400 then what is the IF frequency and can we change this
to some other value? Correct me if the question I asked is wrong.
Thanks,

Many of us use Fedora. Either works fine.

Using Ubuntu is easier and installing all the dependencies on it is quicker.

Hi Boris
I think you need to specify costas-alpha as 0.05 and gain-mu as 0.001 as your
starting point. Hope this would help.

I'm just starting out working on the GNU radio and I'm wondering is there any

there's a sprectum analyzer demo available? I haven't had any luck as of
yet.

Hi all-
as part of my on-going efforts to acquire 2 channels (two independent
signals) on my USRP2 with an LFRX board, I would like to know if there is
an equivalent to the subdevice setup code that exists for the USRP1. For
example:
if not self.u.set_nchannels(nchan):

I'm editing some of the .cc files and would like to know the preferred
method for performing thread synchronization in C++ code. In particular, I
noticed that the set and get methods that are called on the gr_oscope_guts
class originate from a different thread then that of process_samples, and

This is a great achievement. I tested it with an old 2GHz P4 laptop (but with good USB controller) and was able to reach about 41MB/sec. The tests were with/without FPGA HB filter in one direction using your pre-built images.
Could you try to set different fusb parameters? I observed that, since
I agree with you doug. After reading through the BBN code, that seems like
why they did that. DBPSK and DQPSK appear to be backward compatible
decoding wise.
I think the reason why you cannot transmit/decode DQPSK packets is that the
entire packet is encoded as DQPSK and not part DBPSK and part

Hi everyone,
I want to ask if someone has tried the benchmark-rx.py/bencmark-tx.py
(gnuradio-examples/python/digital) in the the 3.1.3 realease with qpsk
modulation (-m dqpsk) for transfering user data? I connected 2 usrps

Hello,I have modified the fmradio.py andfmtx4.py code to make a multi band fm
transmission system.The problem is as I increse the number of channels,The
interference increases.How do i control the gain and also the SNR of the
