Hi Dr Schmidt, and everyone here!

?

I'm finally getting to start the build of your 20W PA semi-kit. I will eventually use it with my T41 build as I get there, but would like to experiment a little with it as a standalone amp in the meantime.

?

Does anyone have a generic block diagram on how this would integrate into an arbitrary other radio? I assume the following needs consideration:? rf-in power matching ( via the input power pad on board)? , rf-out lpf , ptt voltage interface conversion (if necessary), and TR switching? Anything else that would need to be handled?

?

If a specific other qrp radio integration has been documented someplace, I'd be interested in reviewing that too!

?

Thanks! and 73, Wayde VA3NCA/AD2GX?
