Default 40 MHz - Is it legal in the USA for RC?

I read somewhere that it is not legal to use a 40 MHz signal in the USA for RC. Is this accurate?
Why or why not?

Regards
Rob

You can find a listing of frequencies used in the US at the AMA website, here: [link]http://www.modelaircraft.org/events/frequencies.aspx[/link]

40 Mhz is not approved for RC use in the US.

Here are the listings of allowable RC Frequencys for many other countrys: you will find a wide variety of bands in use and even in cases of a common band in several different countrys the breakdown and channalization may be different and therefore illegal in one of the countrys.

Do not use forty in the US.

Even if 40 MHz is a public frequency and it’s not “illegal” for R/C I certainly would not stray from a frequency designate as an R/C frequency. The FCC has designated that frequency for another use. So the chances of brining your planes home alive are very slim.

Try Googeling 40 MHz under the FCC and see who you would be interfering with your flying.

This is a chart of the current US frequency allocations from the FCC. As you can see in the document 40 Mhz is allocated for land mobile radios. If you use 40 Mhz for RC you would be taking a huge risk of getting interference from other non-RC radios in use in your area. IMHO it's not worth the risk.
