Thanks Martin, The problem with connecting the tagged stream directly to the modulator, is then how do you align bits to the byte boundary etc. after the demodulator, which is the main issue I was thinking with that. cheers Chris ___ Discuss-gnuradio

Indeed, don't use a throttle block for anything other than a simulation not involving hardware. What sample-rate are you using, and are you getting overrun or underrun indications ('O' or 'U' printed). on Jan 13, 2014, Marqo Torres marqotor...@gmail.com wrote: Hello, I am working on a real
