Hi. I live in sweden and here we fly at 35 or 40 MHz but if i buy a radio in usa I will get 70 MHz in the radio, so is ther anyway to fix this?

Marcel

Is there a law that prohibits you from using 72 mHZ equipment? If not, enjoy it, since you will not be competing with others for the same "channel". On the other hand, if 72 mHz is reserved for other uses (cell phones for instance) don't do it because you could loose your plane (or get a fine, I suppose)

Hi Marcel,

No, I don't believe you can get a 70 MHz radio converted to 35 or 40 MHz. You will have to buy a radio specifically for that band. In the US there are Police, Fire, and other agencies using 35 and 40 MHz so you won't find any RC transmitters being sold on those frequencies here.

Okay. Thanks!
I have e-mailed my club if I can use it.
The problem is that the radios in Sweden are quite expensive, the 6EXA costs 179.99$ at tower and at a cheap place in Sweden it cost 329.56$, it's a large deferens...

Marcel

how about one of the module based radios? maybe get a module on your freq in sweden but buy the radio in the US?

Probably a good idea, I just don't know what that is... please explain it to me!

Some transmitters have "modules" that plug into the back. There are some that are a single channel, and some that can be switched from channel to channel. (Generally called a "synthesizer", or similar term.)

I would imagine that a local retailer could order a "module" for any transmitter that you bought, but I'd check first to see if modules are available in your frequency range. (They should be, but....)
Dennis-

Neo, you might look into buying one of the US tranmitters for the 6 mtr. amature band (50-54 Mhz) and have the seller. or some one there install the xtal you want and repeak the xmtr down freq. Any good xmtr will swing down 10 Mhz. Just a thought but amatures do things like this all the time to use equipment we get cheep that was intended for some other use.

Good luck, I hope you find a way--73

Dennis:
You bring up a point that has been bothering me. My JR Radios have the "module" you are talking about. I believe you are talking about the crystal, which in some radios can be changed very easily without opening the case. You obviously have to match a Receiver crystal with the same channel with the one on the Transmitter. The problem is, you are not allowed to change it (?) since by Federal Law, you are supposed to send the transmitter in for the crystal to be plugged in and the radio "re-tunned" to that frequency. This can only be done by authorized companies (?). I know of someone who has changed crystals back and forth in order to use his radio on planes with different channels, but this is supposedly ilegal. He says he has never had a problem.
Can you comment on this?
Thanks
Luis

--U.S. Federal Law has no bearing in Sweden, where the original post contributor lives....

--Your JR crystals are not the same as the module DBCherry is talking about (see attached pic). They plug into the back of certain radios and are self contained Tx modules.

Sounding like a good idea... anyone know where I can find one? I have searched but whiteout any results...

Luis,
Gary's right. A module is completely different than a crystal, in that a module has all the "tuned" components contained inside. The FCC is not concerned with changing modules because it does not "detune" the transmitter.

neo,
Not sure where you could get one, but try these:
