* Magic coupling constant between GrAtscFPLL and GrAtscBitTimingLoop.
* Trust me, you don't want to mess with this.
*
* The agc block buried in the FPLL indirectly sets the level of the input
* to the bit timing loop. The bit timing loop's convergence properties
* depend on the the mean amplitude of it's input. This constant ties
* them together such that you can tweak the input level of the bit timing loop
* (somewhat) without screwing everything.
