Tom,

Soundcard sourced digital modes are really SSB signals and need a linear amplifier.

Hi Ed.

I am more interested in a non-linear class C or higher amp for those bands as was not thinking to run modes that need a linear amp. WSPR, a WSJT mode, WSQ, and the like.

With the recent expansion of use to 630m for the K3s and upgraded K3
which only transmit at nom 1mw, a question arises:

Is there interest in a linear amplifier taking 1mw drive to produce
either 25w or 100w?
