[-] RE: [ICOM] IC-718 Speech Processor

[Paul Playford]

Many years ago I homebrewed an rf speech processor.  And in order to set the 
processing levels I ran the audio output into a tape recorder, tweeked the 
level, listened to the results, and tweeked the level again.

When I went above 6dB compression the audio sounded terrible.
