hi,
I have the latest gnuradio installed on my Ubuntu 10.04 computers and
two USRPs with RFX-2400 cards. I tested the benchmark_tx.py/benchmark_rx.py
and benchmark_tx2.py/benchmark_rx2.py
with dbpsk and dbpsk2 modulation schemes but only the old schemes work.
1. With old schemes both usrps transmit and receive when tested in both
tx/rx modes.
2. With the new scheme one of the receive computer displays 'false '
for almost all the packets received. I didn't see any successfully
received packets.
3. One of the USRPs in the receive mode doesn't even acknowledge a
transmission and hence the benchmark_rx2.py script doesn't print any
thing on stdout.
What changes in parameters should I try in order for them to work?
Thanks

Some modulation schemes are more sensitive to frequency offsets than
others.
Try that.
