ikj1234i ikj1234i at yahoo.comAs to the specific question about throttling - having a throttle block in a flow graph should /only/ be done if there is no hardware source or sink (usrp or soundcard). If the throttle block is in the flow graph at the same time as a hardware block you have the two-clocks problem. As for optimal sample rates using the USRP the slowest rate supported by the hardware (i.e., the highest decimation rate) is still more than enough for recording/capture of P25. 2M is overkill unless you're trying to capture an entire band 2 MHz wide. In playing back a file and displaying the result in a GUI is the case where you need a software throttle... Max --- In op25-dev at yahoogroups.com, <md123 at ...> wrote: > > Hi guys! I am wondering what is the optimal sampling rate for capturing of P25 transmissions. My main problem (aside from not getting audio) is that, while I can successfully capture at upwards of 2.0M, I can only play back at around 56k without greying out the gui. I am a little confused about this because I thought the throttle would control the clock speed for play back. Any suggestions on configuring the settings would be greatly appreciated. > Cheers, > Matt > ------------- > -------------- next part -------------- An HTML attachment was scrubbed...
