My final stage is 24 IN4148 diodes!

I've always wanted to transmit with a rig with no transistor (or valve) final amplifier stage. Yesterday I did it using a diode balanced modulator connected must before the antenna. Admittedly it was only a few milliwatts and it was WSPR but the signal was detected thousands of kilometres away.
