Hi,

I'm running Ubuntu 11.10 + UHD 003.004.000 + USRP2.

I'm trying to run a transceiver script for OFDM, which has both the tx and
rx flowgraphs (very similar to tunnel.py except the TUN interface). But, I
can't seem to receive anything successfully in that case. Even the preamble
correlation fails, it barely sees anything substantial in the air at the RF
end.
On the other hand, if I just disable the uhd_transmitter in the script, the
receiver then works just about great.

I've run the transceiver script earlier on USRP2 with the eth driver -
could it be something to do with the UHD? Is it possible that the
transmitter is in some way locking the receiver?

P.S: Individually, tx and rx work just fine.

Thanks
Apurv
