What Futaba says about their dual conversion is obviously true. And keep in mind that it's their advertising approach as well as their design choice.

Keep in mind that dual conversion is not the only method of clarifying the incoming signal. So don't make the mistake of assuming that if it doesn't say dual conversion that it will have less range or that it won't filter as well.

Don't let advertising catch-phrases drive your choices.

If the RX you're thinking about buying says it's dual conversion, excellent. That's how they chose to make it better.

If the RX you're thinking about buying says nothing about "conversion", excellent. They're using another method of filtration and it just might be lots better. You want to know how to tell? You can't. About all we have is the advertising BS. And some of the BS happened onto words that really catch the imagination. And wind up in our base of "sound byte wisdom".
