Re: {Collins} Electro-Voice on a 32S-1



In fact, your typical damped wattmeter motivates the op to do exactly the
wrong thing.  Turning up the mic gain does produce more indication because
the flat topping helps push & hold the needle higher on voice peaks.

As noted in the earlier post, ask little of your ALC.
