IAN LANG ELECTRONICS
For those of you who enjoy RC models, here is a list of frequencies you can use. All of these frequencies are licence exempt but you must not use a transmitter with a greater ERP then 0.1 W. You may attach an RF amplifier to a receiver but not to a transmitter.
Your equipment must comply with ETSI Standard EN 300 220
and EN 300 683
Your equipment should have the "CE" mark on supply which signifies it meets standards.It should have channel spacing of 10kHz except on the UHF band where it's 25 kHz.
The 27MHz frequencies begin at 26. 965 MHz and rise in 10 kHz bands until 27.275 MHz except in the case of older equipment which rises in 20 MHz bands. The channel number allocations run from 1 (26.965) to 32 (27.275)
This band is a general use band and as such can be somewhat overcrowded. Many children's toys use this band.
The 35 MHz frequencies begin at 34.950MHz (channel 55) and go on to 35.300 (channel 90) in steps of 10KHz.
Only flying models may use this band.
The 40MHz band runs from 40.665 MHz (channel 665) in steps of 10kHz to 40.995 MHz (channel 995).
Flying models may not use this band. It is for surface models (including boats) only. This band too is used for children's toys.
UHF band or 458MHz
This band runs from 458.525MHz to 459.475 MHz in steps of 25KHz which makes it suited to FM transmissions.
Although it is a general use band convention is that at and above 459 the band is used for flying models. Beneath that, it is used for surface models. This band is unique to the United Kingdom and as such equipment is scarcer and more expensive.
In addition the 433 MHz band is available for telemetry between model and operator. These are 433.05 to 434.79 MHz.
Fairly recently 2.4GHz has been added to the available spectrum but it is not clear ow succesful this band will be. A short range can be expected and it is susceptible to wanton interference from a wide range of telecommunications devices.
