I am not talking about setting the gain in software, spectrum plot gain for

I'm talking about the hardware gain setting controlled via I2C

I have an example, in GRC, attached.
It uses an audio source, which is common to all three modulators, this
goes to a fractional interpolator to interpolate up to the basic
sample rate of 200Ksps, which is an integral divisor of 100Msps

binaries in both Windows and Ubuntu. The problem occur while using the
latest binaries. What can I do again?
