Unfortunately, my uBitx Raduino died,and i haven't had the time to fix it and test my circuits. I should get to it this week.However the simulations are clear, it will work. The fix though is to change the impedance to 25 ohms, of the filters, which allows the capacitor values to triple.That reduces the effect of the relay capacitance. The output transformer needs to be rewound, the filters changed, and a 1:2 transfomer added to get back to 50 ohms. That is the only artwork change, the transformer.
