TX: vfo and xtal oscillator and complementary pair driving a pair of IRFP450 HEXFETS to 100 watts. Amp: 4-400 (a pair) grounded grid Linear amp, running about 300 watts. The die-cast box in the tx is the vfo and xtal oscillator and complementary pair driver. The big coil is ex one of our old 2182 khz transmitters, you can see only a few of the turns are actually used. I used Alan's spreadsheet to pick the capacitor combination for the PA.
