Hello everyone, I have posted a similar question before but didnt get too much attention thats why I am posting this question with hopes that I will get some response this time because I have tried to make the question simpler.
In one line the problem is I am so far unable to configure 2 RX channels with RFX2400+USRP1. I have read mostly related mails on this forum and GNURadio examples as well, I am doing exactly what is mentioned in all these but still no success. To understand the problem please read the following. I implemented spectrum sensing, first with single RX channel (it works), and then I modified it for 2 RX channels and here I have problems. I first tried sensing with a single channel (This code is well known and some where available on this forum or GNURadio examples), it is working fine. In this code I simply display the maximum value of each FFT scan. When I have some data source at the frequency which I have set (2.41GHz at the moment) then I can easily see it. This code is attached as "sensing_single_RX_channel.py" at the end Then I changed this code for two RX channels, one one path I kept the same graph for sensing and the output of other graph is sent to a file. If I forget the output of file for the time being and focus on other leg of the graph i.e. spectrum sensing even then my sensed signal is too weak. For example if with one RX version I was receiving value '75' then now I am receiving only '10'!!!!!!!!!!!!!!! This 2 RX channel version is also attached as "sensing_2_RX_channel.py" Its very easy to run these files on your system. Can some one help me to find what is the problem.
