Hi,

I was trying to see what frequencies we can use USRP to tx and rx data,
with
/gnuradio-examples/python/digital/benchmark_tx.py and benchmark_rx.py.
The
daughter board we are using is 2.3-2.9GHz transceiver. But benchmark
only
worked in some of the frequencies, like 2.36-2.49GHz. when I was trying
other frequencies, wither above 2.5G or below 2.35G, benchmark_tx shows
there are data packets sent out, but benchmark_rx got no packets.

Can anybody help me with my problem? Thanks so much.

Yanyan

I believe there is an ISM filter that you have to remove.  I assume
you have an rfx2400 or similar.  See the discussion here:

Thanks, now I can see why. Yes we are using RFX2400, but it seems not
easy to
remove the ISM filter.
