This my solid state AM rig which is a "work-in-progress".  The RF amp is a class C circuit that  is driven into saturation by a square wave to improve the efficiency.  As shown, it is modulated by an audio amp, giving about 50 Watts of carrier, but plans are underway to pulse-width modulate it.                     

	I call this my "Franken-Design" rig because it is a horrible looking monster, but it really gets up and goes to town!    The RF power amp is on top of the  120 Watt rms amplifier which is used  to modulate it.  The Heising choke and capacitors are on the top right. The RF drive is supplied by a DRAKE TR-7.
	This shows the two FQA11N90 FETs , the IXYS 414 I.C., the output transformer, the driver circuit board and the power supply filter network on the heat sink.  The P.C. board in the foreground is a sequencer.
