i did make some progess again but had to amplify collected audio
samples using modified usrp_rx_noguiy into a file. That was working
great before successfully resending it i had to normalize and amplify
the signal and
then resend it using fm_tx4.py. So my question is the following:
Can i amplify the signal before sending? How do i do that the easiest
way in python? Setting the amplitude value higher in the sourcecode?
