472Khz 25W PA

The 25W PA for the KX3 472KHz transverter is a clone of the GW3UEP version so I'll not repeat the circuit diagram.

It is getting a bit cold in the workshop and soldering doesn't work as it should right now so will complete this later but the basic layout is complete.

I have used M3 Nylon screws as stand offs for the horizontal coils. The vertical coil I started it 15mm or so up and glued (hot melt glue) it to the PCB.
