I am going to order Telemetry soon and I am interested in RDF900 but I have couple of questions.
1. Does it work for a 5KM distance?
2. I am currently in Europe where 900Mhz band which RDF900 uses is not ISM band but I just need to test it for a few flight and then go to another country where it is allowed, So if I can use it, is it going to make problems and is local authority able to locate me?
But in some reviews I saw it was working up to 10KM.
Can I use 433Mhz without any problem in Europe(Germany)?
You may adjust the minimum frequency of the RDF900 to be above 916 so as to be outside GSM spectrum and try your luck....
I don't think the whole of Germany is monitoring this frequency ;)
Thanks but it seems a dangerous side :D , 433Mhz seems legal though.
Do you have any idea how long can I go with it ?
