[Discuss-gnuradio] WBX <70MHz

[Sharif Shaher]

Hello,

I am trying to tune the WBX to 60MHz, but everytime I do
I get an error.  If I do it through usrp2_fft.py it says "Failed",
if I do it through my c++ code, I get the error
set_rx_center_freq(6e+07) failed.

I used the u2_flash_tool to "burn" txrx_wbx.bin to the SD as follows:
sudo ./u2_flash_tool --dev=/dev/sdb -t s/w apps/txrx_wbx.bin -w
It appeared to work fine.

Also, Matt directed me to txrx_wbx.bin at
http://gnuradio.org/releases/usrp2-bin/trunk/
This is the one I used.  I also "burned" u2_rev3.bin in a similar
fashion as above (sudo ./u2_flash_tool --dev=/dev/sdb -t fpga 
u2_rev3.bin -w)
and it seemed to work fine.  Got that from the same link above.

When I tune to freqs over 70MHz, everything seems to work, but
once I get around 68.5MHz, I get these errors.

Any ideas would be greatly appreciated.

I am using gnuradio-3.3.0-rc0.

Thanks,
Sharif
