Radio frequencies
Transmitters for model air planes must use the legal frequencies approved by the German “Federal Network Agency“ (Bundesnetzagentur) in the 27 MHz-, 35 MHz- and 40 MHz-Band. See the list of frequencies on the websites.
2.4 GHz transmitters have to fulfil European Standard EN 300328. The maximum equivalent emission power EIRP is 100 mW peak. The transmitter must be CE marked and bear the declaration of conformity.
Note: Output peak power of Spektrum is programmable by service stations. Alternatively 100 mW HF modules according to EN 300328 are available.
Finally, on behalf of the German organizer of the F3D World Championships 2009, we are able to offer a solution regarding the European standard for transmitters in the 2.4 GHz band. As most of the concerned pilots are already aware, that standard differs between Europe and the rest of the world.
When arriving for the World Championships in July, everybody equipped with a 2.4 GHz transmitter of JR or Spektrum make may chose between two opportunities.
1. The pilot presents a document - for instance a mark on their transmitter or in their manual - which demonstrates the conformity to the standard EN 300328. One important part of this standard refers to a power output of no more than 100 mW.
2. If this document can’t be presented, we will provide a licence of exemption. In order to refund the licences fees, we have to charge all pilots concerned 120 Euros per transmitter. After some negotiating, German authorities related to frequency usage (“Bundesnetzagentur”) promised these licences for all those 2.4 GHz transmitters, which don’t meet the European Norm 300328. Every licence regards the usage at Ballenstedt and at the associated airfields between July 20th and July 26th. The compliance to the EN 300328 will be checked during model processing. Any utilisation fee will be charged cash.
Further on, the authorities made a condition not to use more than six (6) transmitters at the same time. That condition demands impounding all transmitters despite the 2.4 GHz technology reduces the danger of interfering to almost nothing. To avoid getting charged with 120 Euros per transmitter, every pilot concerned may approach the manufacturer of their radio in order to change the transmission to European standard. The manufacturer will reprogram the radio, which includes the totally sweeping of its memory. If choosing this procedure, please don’t forget to ask for a document which demonstrates the compliance to EN 300328.
Note: If a pilot owns two or more transmitters, one transmitter is in use only and therefore only one transmitter must be licensed.
