Just curious if anyone used their gnuradio/USRP platform this past
Field Day? If yes, I'd like to hear in what capacity. For those of
you who may not know what FD is

Theres some questions that have been puzzling me,
when i used the usrp_oscope , there are 2 signals one for channel 1, and one
for channel 2; do they resemble the Tx/Rx and Rx ? if so why when i place an
antenna on one of them there's no difference in the signlas?Is there a way i
can isolate the
Hello Everyone
I am currently working on binary file transmission from one system to another,
but couldnt figure a way out yet.
Using tx_voice.py when I send a binary file with just an arbitrary stream of
ones and zeroes, data is read and transmitted as packets well. But

hi..
i am trying to embed a fixed sequence which i want to recover during
demodulation. I have read from the previous archives that it would be easier to
embed it in the payload part.However, as soon as i add anything in the payload
part, and try to receive using rx_voice, i get an error saying

Thanks Chris, and the idea of a coils array is great!
Thanks for the link Eng. Firas :)
My idea is to generate 100 pulses at 6000 Hz per second for a duration of
1/200 second (this values are not absolute and it should be easily changed).
Betwenn pulses, the script have to "switch" from this "tr

Data format is optional using the itemsize value as the first argument

Hi,
I have a small question regarding the frequency range and bandwidth of
the DBSRX daughterboard from www.ettus.com. According to the
daughterboard datasheet [1] the frequency range is from 800 to 2400
MHz, and the adjustable bandwidth is from 1 to 60 MHz. However, the
datasheet for the MAX2118
16 matches
