It might cost another $0.20 to have a red LED on the front panel that
lights up when audio peaks from the mike amp exceed some level
at which the mixers start to misbehave.
Not much point in doing so till it's verified that the IF amps?
have a consistent gain from rig to rig.
Some way to measure the RF out of T2 into the 30mhz LPF?
would also be good.? ? Ideally in such a way that it could be used
as a probe into other parts of the rig.

As to mic gain being a poor solution.? I'll apply your logic.
For the people using them it was a easy solution.? They?
got the power they wanted and are flying blind and really?
don't care as the solutions require them to do work.
