This project is a major masterproject which heads several smaller projects. It is my first occupation with Software Defined Radio and I am getting into this intersting field step by step.

1 Scope

1.1 Get to know the USRP2 and get it running

  • 2010-10-20 Today my USRP2 arrived. Brought to me by FedEx. Got to pay VAT but well, that's fine.

I decided to insert the LFRX receiver board first and only in order not to break the TX board for a undecent SWR. After a while I discovered that the tool

find_usrps

will identify the USRP2 when connected directly to the GBit port of my desktop computer. Well, it does. Obviously the USRP does react on network access. Now, the only thing it needs to do is to run. Therefore I tried out the tool

usrp2_fft.py

and it gave me a wonderful spectrum scope of short wave frequencies.

1.2 Receive the first signal

1.3 Transmit the first signal
