hello marcus
thanks for your reply,i really read the tx_voice.py
,i am using E310
i set the audio card samp rate to 8KHZ
and i did not resamp the 8K of audio samp rate to the GMSK symbol rate
i see that there is s resample block before UHD_TRANSMITTER,resample the code rate from 8K to 100K,and the uhd_transmitter samp rate is 100K
but this program do not work well,so i delete this resample block ,and the program work better than before.
i think that the code rate into uhd_sink is not match with the samp rate
because i see that the uhd will do a Interpolation itself,so i set code rate 100K does match 100K uhd samp rate.
i want to ask ,if the uhd_sink samp rate is 100K,what is the code rate that is ok ?
