Hi,
If I wanted to experiment with nonlinear RF finals and digital modes with my uBitx, would doing something like changing the bias and drive for the uBitx finials, driving them harder with little or no DC bias, be a practical way to do this?
Would that provide an efficiency gain that would let the uBitx putout more power (or at least generate less heat) with the same finals, without a redesign of the RF output stages?
Likely I'd build a simple digital RF chain and switch it in, close to the final stages, when I want to try these digital modes.?
