Hi Daniel, that README refers to things of the past (when you specified a decimation rather than the sampling rate you want), and "USRP" refered to what we nowadays call the USRP1. In the version of the usrp_rx_hrpt.grc, from which the .py gets generated, the USRP source is just configured to 4MS/s. The question is whether 4MS/s is really the optimum rate; I haven't studied the HRPT signal enough to answer this. In principle, for the 100MHz devices (N210/N200), 4MS/s is a suboptimal rate, since the decimation (25) is odd, and I'd try with something less strange, like 5MS/s.
