[Discuss-gnuradio] USRP2 Source Sink blocks tranceiver

[H.Raza]

Hello everyone,

I just wanted to ask that if it is possible to use a single system hooked up
to multiple USRP2's (4 in my case) to act as both a transmitter and receiver
using the USRP2 source and sink blocks in GRC. The source and sink blocks
are working fine independently, but if I use them in the same flow graph the
source block outputs garbage or something which I can't really make sense
of. I've checked using QAM modulation, FM and just sending plain
constellation points/symbols, but at the output of the source I'm receiving
only noise.

Attaching the Screenshot of my test flow graph running showing an instance
of what I am getting. In most examples and demonstrations I've seen
transmitter and receiver on different systems but as we have not set the 2nd
system up yet I can't test using that, so I was wondering if it is possible
somehow to use only 1 system as a transceiver. I am using separate USRP2's
as shown in the screenshot for transmit and receive, eth1 and eth4 in this
case. Any help or insight into this matter is highly appreciated.

Regards,
Hassaan
