Hello Eric,
In USRP1, I don't want AD9862 to use in my application for many reasons.
Am looking for changing four parallel pipes of ADC's into two parallel pipes
of ADC's(having interleaved IQ as in the case of DAC's).
I need only changes required to be done in FPGA. Although i know that the

Hi Mark - I'm glad you got it working; if you installed all of the
background dependencies with MacPorts, compiling GNU Radio should be
as simple as:
[fix bootstrap]
./bootstrap
./configure
make
make check
sudo make install
with no other options. IIRC, the 3 primary environment variables yo
Hi,
Your reply is related to running the FFT on the CPU, right? Do you have any
experience running it on the FPGA of the USRP1 or USRP2?
No, but I know that radio astronomers do this.
I have done FFT with CUDA. As long as you can keep the data inside the
GPU for long enough, you can get

So far, the only way I've been able to get gnuradio to link against
libusb-legacy has been to uninstall libusb-1.0. Even when I overrode pkg-config
by setting the USB_* variables, it'd still (apparently) link against libusb-1.0
and then crash at runtime when it couldn't find the "_usb_debug" sym

If you use grep, you can find places in the code where it is used, and
then answer your own question.

Hello Tom,
Can you explain me why should gr_peak_detector need negative inputs ?
What about the variable "look ahead" ? I wrote in the last message that
"look ahead" has no function in gr_peak_detector. Do you know how can I add
this feature in peak detector ?
Thanks in advance

Hello,
I am attempting to build an analog front-end to a USRP 1 device. I have
selected a VCO that will suit the frequency range we are looking at: It
is an RFVC1800 and has a tuning range of approximately 7.4 - 12.4 GHz
over a 13 volt tuning voltage. As this VCO is very sensitive to

Alas, no. Once it stops receiving, it never starts again. Time to dig into the
firmware.

Thomas,
I'm some affraid to "fry" the DBSRX, draw too much current for the
amplifier, so I use a "general" power inserter instead of feeding the
Antenna bias pin on the daughterboard.
I use a cheap Johansson (BE) TV power inserter (VHF - L-Band) so I wont ever
have to worry about damaging the
Thanks Thomas,
We'll try to replicate the antenna using a USRP1 within a few weeks

Hi,
What antenna are you using for GPS?
If possible, can you give us a link or specifications of it.
Beside some geodetic high end antenna (Trimble), we'd like to test the
