Hi,
This is sort of picaxe related and I am sure it will help future users who are not sure, if someone can answer the question ;-)
I have been looking at a number of different radio transmitters and receivers from a number of different websites, both AM and FM, UK and non-UK. I am aware that in the UK 433mhz is an unregulated band so ideally a transmitter and receiver on that band would be great, however, it comes at the cost that it is a very crowded band as everyone is using it for garage remotes, model helicopters etc, you name it and it is on that band.
I notice there are loads of radio chips on RS which broadcast on many different frequencies which are of course short range, normally 500m-ish. There are also chips on sparkfun on 315mhz. So here is the question, what frequencies can I broadcast on short range in the UK?
Thanks for the help!
