mmmh the problem probably comes from transceiver: usrp_standard.cc:1024: virtual bool usrp_standard_tx::set_tx_freq(int, double): Assertion `dac_rate () == 128000000' failed.
For patching GNU Radio to 52 MHz, I need to comment the line assert (dac_rate() == 128000000); at line 1024. How can I modify that?
