Radio gear from the US??

[Sammy]

Hi,

Here in the UK, we use 27mhz AM and 40mhz AM

I am looking to buy a car from the US, which, I guess, comes with american radio.

Please could you tell me if I could use this over here?

Also, if it didn't work, would the servos be compatible with 27mhz as I could change the transmitter and reciever.

Many thanks,

Sam

hi Sam...in the us.we use 27mhz and 75mhz for ground

and yes servos will work on any frequency

[theshopkeeper]

75Mhz is used for runway marker beacons in the UK.

If you remember the episode of Only Fools and Horses with the satellite dish you'll get an idea of why the radio authorities wouldn't be very happy *if* they caught you using that freq...

[Sammy]

Right.... yes I know what you mean

Is 27mhz a common freq. in the US?

I have seen some people use 35mhz, is this illegal over here?

Many thanks,

Sam

35mhz is legal in the UK but it is ONLY for aircaft!!

Boats and cars can only use 27mhz and 40mhz.

Using any other frequency in the UK is illegal and 'IF' you're caught

you'll be fined and and your stuff will be confiscated!!

[Sammy]

OH I'd better make sure that I get the right stuff...

Anyone know the chance of gettin caught?

Personnaly I use 75mhz in France, which is totally forbidden, but since the president of the club also uses it... I was actually so tired of runaway hiluxes, avantes, and whatever "precious car I had that I decided to taje strong measures. In any case law regarding frequencies will be "europeanised" next year...

I wouldn't even contemplate using the wrong frequency, it not so much saying what is the chances of getting caught, it is the consequences of a glitch you may cause to some other poor sod's model.

Regarding your question, you could use a french 26mhz radio and use it "legally" in europe with a 27mhz crystal that is as close as possible to upper limit of the 26mhz band (i.e if it can normally go up to 26.915, 27.000 should be fine also). Normal radio do not normally mind to be used on the edge of their "normal band", what I do with 40mhz JR radio, is just have them tuned by Graupner after sale service so as to operate in France (41mhz).

For the 75mhz frequency, I just do not care as this freauency is not officially allocated in France (french telecom authority http://www.anfr.fr/pages/tnrbf/A7.html).

A good thing is just to have a look at your local telecom agency and consider what is the normal usage of the band you want to use: if these are alocated to the army, airplane communications, etc... I'd rather not use them . if the band is free, just go for it, but ask first with your club if this is Ok for them. Some clubs are prety strict, others are more tolerant.

Finally regarding land / air allocations, this allocation was more in terms of less dangerous / much more dangerous, and I remember that when quarter scale cars started in France, they were allowed to use the less over crowded "air-plane" frequencies.

27 is very common in the US. All of the Traxxas RTRs have 27. Most likely, many of the other RTRs also have 27.

I've never heard of 35 in use in the US, but maybe the airplane guys use it. I know they use 72 for planes over here. 72 used to be usied in cars too, but this changed in the early 1980s.

The latest here in the US is 2.4Ghz. There is a new system called 'Spektrum'. It can automatically find one of 70-odd channels. No crystals. Just sync it one time to your receiver and its ready to. Supposed to be glitch free.

All you can use is listed on here.

After reading through this topic a question came to me as to how you can have so many people racing at once. I know that there are different crystals in the 27Mhz range adn there must be something along the same lines in the 40Mhz range. BUT, not everyone is going to go along to a race with both types of controller and receiver. How do they do it? Yet another black magic art for me to learn about!!

you only need either a 27Mhz set or a 40Mhz set with a few sets of xtals and there you have it

When we were flying model aircraft, which I know is a lot more dangerous than land based stuff, each frequency had a different coloured pennant which you had to have on your tranny ariel so that no same colour pennants could fly at the same time.

Really it should apply to ground based stuff as well especially if there is some guy around with a stonking great 38cc monster nitro truck!

Most clubs would use a "peg-board" that achieves the same thing.

As far as frequencies go - 27MHz is fine in the UK. Don't even think about touching 75MHz - it's breaking the law, and it does nobody in the RC community any favours.

[splod1]

Sorry sosidge, forgot to mention the good old peg board, at least everybody knew at a glance what frequency was being used by anyone in the air at the time.With some guys with £2000 worth of plane zooming around, it was pretty handy to know!
