[Elecraft] K3_630M_Pwr Amp

[Ken Roberson via Elecraft]

Hello All,
My two cents, I would start with a homebrew class D pwr amp.This will get you on CW,WSPR,JT9 and a few other digi modes.The class D switching mode FET power amps are easy tobuild and easy to drive.This will get you started and later you can build a class A pwr amp.Most of the narrow band modes that you will end up using do not need classA,AB mode pwr amps.Remember the bandwidth of the 630M band is about the sameBandwidth as two SSB signals.
