[Discuss-gnuradio] Arbitrary symbol rate transmission by USRP2.

Arbitrary symbol rate transmission by USRP2. I would like to transmit dqpsk 1,536,000sps with using benchmark_tx.py and benchmark_rx.py thru USRP2. Since USRP2 does have 100MHz as clock source. With the clock, seems decimation and interpolation only allow me at 1,538,461sps(100MHz/65) is the neare
