Have a read guys, UK rules


Do I need an amateur licence to transmit video from my model aircraft?

Airborne transmissions are specifically prohibited in all UK amateur radio licences.
The official information on radio controlled models is at http://stakeholders.ofcom.org.uk/spectr ... ces/ofw311. Section 11 of the page discusses amateur radio, airborne operation and licence exempt video transmission. When we checked in January 2014, airborne transmissions were legal from compliant equipment (see links from ofw311) operating on the 5.8GHz band with a maximum power of 25mW EIRP. The best technique is to use a medium gain receiving aerial (10dBd or more) and a sensitive receiver; a range of around a mile should be quite possible. Further useful information about legal First Person View (FPV) video can be found at http://bmfa.org/Info/ModelFlyingTypes/F ... fault.aspx (link checked August 2014).

Above 25mW you need a Ham licence, as far as I know.
But I don't know anyone that does, and they all use 600mW VTXs

That's taken direct off the amature radio site, even if you have a licence the 25mw still applies for all of the Fatshark channels, and video is not covered anyway in the licence according to the first sentence,

There is trouble brewing in our club because of a couple of bankers, that's why I have been looking at it,
