Another Predicta thread

One idea: order a small sine-wave inverter from the net, that runs 60hz and power it off a DC power supply running from the 220V mains. The cheaper inverters run quasi-sine which would introduce bars from the harmonic distortion on the power wave form, so avoid these.

Thanks, I thought of that ages ago and had completely forgotten about it. When I first bought the Predictas, I was thinking of everything I'd have to do to satisfy their working requirements. As it turns out, sending a PAL signal seems to work, although I have no idea why. I would try my PAL RF modulator, but it only outputs on channel zero, so not an option. I bought an NTSC modulator cheaply from Amazon that outputs on Ch 3 or 4. Does the job nicely
