[Discuss-gnuradio] Need help identifying jammer signal

2013-12-09 Thread Dimitris Siafarikas
It might be an IF local oscillator whose signal is leaking outside. Hence, the small bandwidth and the drifts on that small band. ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio

[Discuss-gnuradio] Transmit from RF1, receive from RF2

2014-03-10 Thread Dimitris Siafarikas
Hi list, here is the thing. I would like to know, how I can create a flow with blocks in GNU Radio companion, in order to receive a signal from the RF1 port of my URSP N210 and simultaneously , receive another signal from the RF2 port of the same USRP. Is there any option defining the port

Ok, let's say I want to Tx from port1 and receive from port2. How am I supposed to do that on GRC? Or is set when I add a USRP source and a USRP sink automatically? From: Ralph A. Schmid, dk5ras [mailto:ra...@schmid.xxx] Sent: Tuesday, March 11, 2014 3:34 PM To: 'Dimitris

[Discuss-gnuradio] Mixing two signals for Radar application.

Hi list, I am in the process of building an FMCW radar. For this to work, I have to mix two signals. I tried to do it with the "multiply" block but no luck. I tried then to see how exactly this block works. It seems that it does not behave As it should be. Referring to theory, I should see the sum

Thank you Marcus and the others for your inputs, I created the flow almost from scratch taking into consideration your words and I came up to this aspect. Here they are: http://imageshack.com/a/img855/7555/7qcr.png(flow) http://imageshack.com/a/img542/9189/5jxl.png (FFT output)

George, site still down? Do you need any help from us to recover? Greetings Something must have been upgraded on the machine, and a significant number of the dependencies needed to run Trac have disappeared. For example, python has disappeared from the machine :P This might take a while, sorr
