Codan NGT,? Its getting old in the tooth now, we are up to Envoys.? Will see if I can take a phone of that.
Easily 125Watts, Codan design there stuff to be tough.? We have these radios in service for the last 15 years with a 1% failure rate in the out back, (quite harsh)

Which Codan model? Can all these SMT caps handle 125w?

This is a LP filter from a Codan radio.? The RF has a straight path to the antenna port. SWR bridge is to the right.? They are very clean.

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.
