Part of the problem here is that Flex won't release the schematic to the

When you have a 24 bit A/D and not looking at the entire spectrum,
this should not be as big a problem as you imply, if gain distribution

Well for the Flex 6000 series you keep one hand on the so called AGC-T

Of note - the K3S and K3 with new synthesizers were essentially +/-
1 dB of each other and swapping the advantage from test to test.
This is good news for owners of the original K3 - the synthesizer
