Default 2,4 Ghz Transmitter to 1,2 Ghz?

Hello,

Is it possible to switch a 2,4 Ghz transmitter into a 1,2 Ghz ?
Maybe there is just a chip, which I have to switch?

And is it possible to gain up the signal of a futaba remote control?

regards, tony.

Are you sure it's even legal to use 1.2GHz for RC aircraft?

I'm curious to what benefits there would be to that.

Yes and No,
It's illegal in the USA but in some countries in the EU it's legal I think.
Here in the EU it is really illegal to use your 900Mhz systems, you can get a very high punishments.
So do you think, it should be possible to switch from 2,4 Ghz to 1,2 Ghz?

regards, tony.

I wouldn't know how to do the actual dirty work, but theoretically it shouldn't be too hard, assuming it's possible. 1.2 is just a harmonic of the original 2.4. However, technically, as an unliscenced user you're not supposed to alter your transmitter's emmisions. That's why they don't sell transmitter crystals (I don't think 2.4GH transmitters even use crystals, even CB radios use phase-lock loops these days).

Most certainly you'll void any warranties.

Ask, and ye shall recieve.

Note that this reflector is for 2.4Ghz only and will boost your signal by as much as 50-60%, however it is now directional, which means you have to keep the reflector pointed at your plane. The best part about it is that you can simply slip it on or off of your antenna in less than a second depending on your preference.

Some of us use this in FPV flight once in a while when we get out to around 2 miles or so.
