Hi Ekko, U means underflow. You're computer is too slow at supplying samples. This means that your computation might be to complicated. More likely, however, is that you configured your sound card to a sample rate it doesn't support, so it uses a different one, and hence, the whole flow graph's rate relations break down. Are you internally resampling from your 8 kHz audio sampling rate to a factor of your GMSK symbol rate? Really look into tx_voice.py, and understand what each part does.
