Fwd: tunnel.py doesn't work on expected frequency

Sorry haven’t post the previous discussion. I took Josh’s suggestion and
it
didn’t change anything. The spectrum in uhd_fft of tunnel.py at 2.412G
and
2.512G (with same bit rate 0.1M) are nearly the same. But tunnel.py
works
only at 2.512G.
The screenshots are attached.

Hi Josh,
I think it’s not the problem of uhd. I updated uhd (replace 1 line
code in db_xcvr2450.cpp),
and under uhd/host:
make clean
cmake …/
make clean
make
sudo make install
But the problem still exists. In addition, when I run uhd_fft on machine
A
and run tunnel.py on machine B in frequency 2.4x GHz, I can see the peak
appears. It means the transmitting works well but failed to receive.

What version of UHD are you running? If you update to latest
