Thank you for your time Mr. Dor. The problem is gain value. I have been searching for 2 weeks about RF. I will continue to search. Thank you for resolve my problem. Have a nice day.

Great. 

Try to send a video of the setup while it is working .

In addition, verify that if there are LED of the connectors they are powered on while working. I don't remember if it should blink or something else.

Thank you for answered.

1. I didnt try to raise gain value. I will try tomorrow after this answer.
2. I connected 2 antennas. One of them for TX/RX port, I am using this antenna for transmitter. And the other one for RX2 port, using this for receiver. The antennas have same gain.

Hey,

2 things:

1. Have you tried to raise the gain values in usrp sink and usrp source?

2. Did you connect antenna to each port? Or is it connected with a cable?

Post a picture of the setup and it can help.

Hello, I have USRP B200 and i use GNU Radio for design. I want to transmit a random signal (whatever, is'nt important for now) I am using the TX/RX port as transmitter and the RX2 port as receiver. I can transmit signal without any problems but i can't receive it from other port. I am sending screenshots to you. If you are help me, i would be glad. Thank you.
