ahhhh :) see i knew i was missing something or else someone else would already be doing it.

I'm still tempted to look at the rf envelope on a scope just to see for myself (into a dummy load of course) because i'm a college student and i want to learn.

Thanks!

Ok first let me state that I've got a Tentec Omni D, so this is somewhat related to this list. I have a VST host program on this computer that allows me to use a "hard" limiter on microphone audio in real time, it's a wonderful tool, I can get probably 20db of limiting with no distortion due to the look-ahead design. it doesn't sound pretty, very "compressed" as you can imagine, but there's no distortion. I also have a VST for a 5 band limiter for fm broadcast. with some modifications it could be band-limited to 300-3khz and be adjusted for SSB. have any of you ever used the most powerful processor you probably have in your shack, the PC, to do your compression/equalization for you and then interface the sound output into your rig?

PS: I'm not a fan of highly compressed audio, it ONLY makes sense when you can't quite get through.

Unfortunately the audio envelope isn't the RF envelope and severely
clipped audio results in peakier RF than unprocessed audio. Gives it a
splatter characteristic, so saith the book on SSB by Collins gurus,
Papenfus, Bruene, and Shoeneke.
