Default 2.4 ghz transmitters legal in US ?

I recieveda 2.4 ghz transmitter with a ARF plane fromBanana recently and after reading a few posts I questionif the2.4ghz transmitters legal in the U.S. ? I looked up what frequencies are listed as leagal in the US a few months ago and 72mhz with a list of channels within this frequencywas all I could find listed by the Fed's for use by model RC planes etc.

Has anyone in the U.S ever had a problem using these 2.4ghz transmitters? or should I stick with my 72mhz systems for everything and swap my ATF plane over to 72mhz?

If 2.4GHz is illegal in the US, about 80% of us are criminals now

Go for it

First of all, the Academy of Model Aeronautics has quite a bit to say as far as what radios we can use for our RC models. They lobby for us with the FCC, FAA, and other government organizations. They promote the use of 2.4Ghz in the US.

I have used 72Mhz for many years, but I much prefer 2.4Ghz over 72Mhz.

Stick with 2.4Ghz. While 72Mhz is still viable, you will have less of a variety of options as the years go by.

I am sure if you contact the AMA or visit their web site, you will find the info you are looking for.

does the 2.4GHz TX in question have an FCC type acceptance label on it? Just because it's on 2.4GHz, which is a legal band to use for RC in the states, doesn't mean it's passed the test and reporting requirements to obtain FCC type acceptance for use in the states.

Good catch!! I was thinking more in terms of 2.4Ghz in general.

Thanks for all the advice. I'm comfortable 2.4ghz is OK and preferred. I looked and found sticker on back side of transmitter with FCC listing number. Thats the key to all of us who never knew what to look for.

Also note that 2.4 is *NOT* an RC designated band by the FCC, and as such, you will find no reference whatsoever to RC in FCC docs. 2.4 is in the ISM (Industrial, Scientific, and Medical) allocation, which is pretty much a catch all for pretty much any part 15 device on 2.4 . . . so, yes, 2.4 is legal in the states, but unlike 72, it shares it's frequencies with a heck of a lot of other stuff, whereas 72 is an RC only set of channel assignments. There are other things *between* the RC channels on 72, but they are not on our frequencies, and do not interfere.
