changing frequencies.........

Guest

how hard and expensive is it to change a brand new radio control tx and rx from 75mhz US frequency to 40mhz on a Futaba Attack 4 channel, brand new set...….

I have been given one plus 2 x hitec 2 channel and a futaba 2 channel by a widow of an old friend who bought them all when serving in the merchant Navy as a captain, based out of west coast USA, and died recently from Alhzeimers…...would it be worth having the new but old and unused 4 channel converted if possible.

You don’t need to convert the 75mhz for boat use Neil...

Believe it or not the FCC regard bandwidths 72.01-72.99 As model aircraft only use...

27mhz-40mhz- and 75mhz are legal to use on ground operated (surface models) rc models....

That is British fcc regulations feel free to google them...

So no conversion of your 75mhz is required if you intend to use on a model boat... In fact 75mhz has better range than 40!

So well done on getting a free radio set, enjoy!

Sorry Aron, but 75Mhz is not permitted in the UK. Your link is an an American site. This is the OFCOM list of frequencies allowed in the UK

I guess that’s another example of not believing everything on google! ( to be fair, no where states US rules on that page)

Bad luck I guess, honestly tho I had a 75mhz transmitter many eons ago and had no issues running my model on it...

I guess there is the “law” and I also guess there if the ability to play “dumb” when it comes to using it.

Reckon it is the same as in OZ as being donkeys we usually follow UK practice.
HAM is an abbreviation for an amateur Radio licence. They, HAM operators have a variable frequency radio and aerial that will transmit and receive to other HAM operators and not just restricted to UK. Depending on the depth of your pockets, determines the size and power of your transmitter/receiver.
Easiest way to find a HAM operator is look out for a huge aerial in the backyard.

My son has a Ham licence back around 1988 I built him a triangle shaped ladder tower 30 ft tall in the backyard of our rented property in Kyneton (Central Victoria Au) he managed to get responses from Canada & USA he was still in college then.
