I have some questions.
Why does the plug-in band module need so much cooling air and what are the
drive requirements?
You realize that this adds to the DAF discussion. Which practically does the
same thing. I have had some nagging issues with the DAF circuit. One is if
you are amlifing AM for example and eleminate the envelope and restore it that
would work just fine. But, if you have multiple frequencies of different
amplitudes that you clip and then restore the envelope, how does each seperate
frequency get assigned it's approprate amplitude?
These last question has nagged me for some time.

Subject: [Amps] New SGC Mini Lini Uses Class E Technology
Greetings, has anyone else seen the new SGC Mini Lini 500 watt output Linear
Amplifier using Class-E Technology and Envelope Elimination and Restoration to
amplify an SSB signal with 90% efficiency? It looks like SGC is the first to
come out with a working Class-E / EER linear amplifier for the Amateur market.
The power amplifier and power supply together weigh less than 5 lbs and you
can hold them in the palm of your hand. The amplifier does need to use plug-in
modules for each separate ham band but still a real achievement in efficiency
and power-to-weight ratio. Go to this address to read more about it
