[Discuss-gnuradio] Changing transmit gain

[Tellrell White]

Hello Guys
I have a flowgraph attached where I'm trying to generate BER curves for different transmit gain values. Right now, I have gui slider that allows me to adjust the gain values, however, I would like to know if it's possible to have the gain values adjust automatically by changing the python script for the flowgraph. If so, I would appreciate any ideas or examples on how to do this.

Thanks
