Using 75 MHz Radio gear

[Wooders28]

Over the years,and mostly down to Ebay,i have purchased RC cars from around the globe.

I have purchased cars from the States and put in 27 or 40 MHz radio gear in them to used them over here in the UK.

I now have 5 sets (transmitter/receiver's) of 75 MHz and wondering if they can be converted to run in the 27 or 40 MHz range so legal to use??

A few that I've come across were capable of running dual frequency like 75 and 27 but they were marked as such. There are internal parts that would have to be swapped in the transmitters and then new recievers for them. You'd probably spend more money switching over than thier worth, considering the prices on some of the new 2.4s out there.

Over here those sell for around 10 dollars if thier in great shape. I finally gave all of mine away instead of trying to sell them.

I wish there was better news on this issue but then with the newer radio sets you get the failsafes that those seldom if ever had.

I had a feeling that would be the case.

Sounding like its not even worth giving them away to someone in the States as the shipping would cost more than the controllers are worth!!

Looks like i will just be using them for spare parts!!

Well I just learned somethin here!! I had no idea it was illegal to use the 75mhz, I still use them in most of my runners, why is it illegal? I just did a quick search and cant find any info on it being illegal over here in Canada

It varies from country to country. 40 mhz has never been available for RC in the US and certain parts of 75 and 72 became restricted to early cell phones here. Futaba back then warrantied switching some to usable bands but that was a long time ago. Right now I have 3 Futabas and a Heathkit that are in the restricted bandwidths but with thier limited range and the fact that they don't even go outside means it's no big deal. However if I were around an airport or signal tower things might be different. You really have to go by whoever is monitoring it in your area. I did find that most of the 2.4 GHZ band is designated for amateur use here. It goes along with the advance in technology that it took all the way up to 2.4 before it got locked in for amateur use.

75 MHz seems to be legal for running surface vehicles in Canda; see: http://www.maac.ca/freq_chart.php

The problem is you do not want to use 75 MHz for model airplanes as they may be subject to more interference than what is present on the 72 MHz band. And using 72 MHz for surface vehicles is bad as it may interfere with model aircraft in the vicinity. The main issue is you do not want to lose control of the model airplane and cause damage with an out of control flying object. Most regulatory requirements for radio equipment are fairly harmonized between the USA and Canada (FCC and IC). Avoid 27 MHz in the USA and Canada due to interference from citizen's band (CB) radios.

I am in the UK and it looks like :- 72.8-74.8 MHz is for "Government" use

:- 74.8-75.2 MHz is for "Airfields in UK", "ILS marker beacons"

:- 75.2-76.7 MHz is for "Government-the allocation is mainly for military use"

So by using a 75MHz R/C equipment i could upset the Military or cause a plane crash!!!! Hence my unwillingness to use them.

OK thanks for the answers, so I should be safe here with my old 75mhz stuff (which work perfectly by the way). A quick look through my radios and I have some 75mhz, some 72mhz, some 27 mhz, and one 2.4Ghz. Im quite far from airports, military, etc and I my runners are, well, runners!! Most get quite a beating from the kids and they keep going (most indestructible RCs ever in my opinion: Hornets and Kyosho raiders), so a little interference now and then wont kill them, dont remember having any
