i just made up a simple code which would do the same.I am attaching the code for reference. I am able to see that the usrp reads the data coming at 910MHz(in my case) which is transmitted by tx_voice.py by writing the data onto a file and then passing it to the demodulator(i am able to see the packets by passing the file as input to rx_voice.py). But, after retransmission at 950MHz , at another machine i am not able to receive any packets. I am able to see that the usrp does transmit something at 950MHz because i can see a spike in a spectrum analyzer at that frequency. I am not able to
get what can be the possible problem. Kindly point out if there is any error in my code. Is there any fundamental mistake which i am doing. I have been mailing quite a lot regarding this but not getting any response. Please help.
