![]() ![]() Usuall Hams have a power limit which they would like to use to best effect. SSB average power is very low compare to other modulation methods. The amatur radio producers have provided the function, because they know it is effective when used properly without affecting signal quality. Whether it represents the mic input on a scope is irrelevant. This also appies to using Proc, when set correctly feeds the amp stages and has the same form on output.

Unless one has an unusual growth of loudness condition as part if one's hearing impairment, called recruitment, I strongly recommend linear aids. I once tried a compression hearing aid and it was torture. Then again I have poor hearing, so I am more sensitive to any imperfections in the audio. It is unnatural sounding and I find it extremely annoying and hard to copy. But you keep doing this on every part of every syllable. Imagine a guy yelling at the top of his voice but you turn down the volume to very soft. This is done to avoid the strong parts of the signal bumping into the ceiling, while still amplifying the weak parts of the signal. Maybe medium parts 5 dB and maybe high parts 0 dB. So what compression does is amplify weak parts of the signal say 10 dB. But then the softer parts of the signal may be too weak to hear. ![]() The idea behind compression is that for a given power limitation, to be true to the signal, one can't overdrive the mic or one will clip peaks and alter the original waveform. ![]()
