If I understood correctly, this it means that the transmitted signal
gets filtered more on the edges than expected?

Note that by setting a sampling rate of 720KHz, the transmission and
receiving work fine.

That is, can I fix the sampling rate warning and preserve the
transmitted signal by modifying the sampling rate (e.g. to 480KHz) and
by adding a band-pass filter before the USRP sink block?

Thanks for your insights. I appreciate.
