Hi all,
I want to make a subsampling SDR using GNU Radio. The available IF is at
1.44 MHz and 10 MHz with 50 KHz BW. Can some one suggest cost effective
hardware suitable for subampling the IF.
Sorry for reposting the question.
Thanx in advance.

Hello everyone,
Just thought I'd let you know about a workshop that we're having
before ToorCon this year on Software Defined Radio. It's a 2-day
workshop happening on October 21st-22nd. The workshop admission cost
also includes admission to the conference over the weekend which is
featuring lectu
Hello
I am interested in the firmware update for the USRP2 that will give the
USRP2 capability for handling UDP network layer and VRT application layer
protocols. Will both of these update occur with the same firmware update?
If not, is there any estimate for when the latter update will occur?

IIRC the ib firmware has a bug not switching the antennaes correctly.
Workaround: set RX antennae to RX2 an
Hello.
I'm trying to build a two-way TDD system with two USRP1 boxes in pure C++
using libusrp and inband_2rxhb_2tx.rbf firmware.
Now I have working system where one USRP1 box transmits data and other box
receives.
I try to make the second box transmit data after it received certain frames.

Hi GRers,
What is the scaling of USRP2 TX/RX samples for float and short type? I
noticed that the absolute values of received float complex samples of

at maximum which match the resolution of ADC/DAC. But ho

It has about an 8-10 dB noise figure

Sorry for starting new thread, I've just subscribed to the list and can't
