My 2p, I mean 2c.

The job of an audio processor is to increase the 'average level' level
of audio without changing the waveform. This can be done at both audio
and RF frequencies (RF speech processors are commonly found in many
ham transceivers).

However, even in the best processors a certain level of distortion is
generated. It's down to the designer and the user to keep this to a
minimum.

Yes, a scope is handy but I doubt your typical processor user would
know what to do with one.

Hi Jay, long time no speak. I hope your antennas are selling well.
