Channel Frequencies


Cleveland Model Helicopter Club uses a Peg-on or Reversed Peg System for its frequency allocation.

The pegboard is marked out with all the channel numbers from 55 through to 93. Each club member carries his/her own named peg and to reserve a channel the peg MUST be clipped onto the pegboard BEFORE his/her transmitter is switched on. It is essential that pegs are removed from the pegboard when flying is finished for the day and pegs used should always carry the pilot's name so as to be able to identify whose peg is clipped to the board.
 

If you go to the pegboard to reserve a frequency and it is in use, you can easily see who is using it and can arrange with them to use it when they have finished. Under NO circumstances should you simply remove a peg that is reserving a frequency. If, however, you suspect that a peg has been left on the board in error (the flyer may have gone home) then you should check with senior flyers at the field and the peg may only then be removed after stringent checks that it is no longer in use. The name on the peg helps again here and is yet another reason to make sure that all pegs are named.
 

There is only one rule to remember here, if you switch on your transmitter with a channel someone else has already reserved then you will be asked to pay for any loss or damage resulting.  If that happens to be a £2500 competition specification model helicopter you just brought down then it could be a costly mistake!!

In the United Kingdom 35MHz is allocated SOLELY for radio controlled model aircraft and helicopter flying with each channel spaced 10kHz apart. It is recommended by the BMFA that flyers regularly operating together on adjacent channels perform an adjacent channel check every three months or so.
 

TX and RX crystals are usually tagged with their frequency and channel number

Cleveland Model Helicopter Club owns a frequency checker and this is often used at the club on busy flying days, usually weekends and also at indoor flying events. This equipment can be used to check both a flyers transmitter bandwidth and also a models receiver.

To identify the frequency of an untagged crystal:

  • If the crystal is marked 34,××× you subtract 40 from the first two numbers after the decimal point of the frequency marking, i.e., 34,980 subtract 40 from 98 giving channel 58.

  • If the crystal is marked 35,××× you add 60 to the first two numbers after the decimal point of the frequency marking, i.e., 35,260 add 60 to 26 giving channel 86.
     

The clubs frequency scanner in use at an indoor flying event

The frequency table below shows all of the channels available and the ones which are used by current club members. If you are looking to join the club it would be a good idea if possible to pick a frequency that is not currently in use. Only one frequency can be used at any one time so if there a lot of people all wanting to fly on the same channel you will have to take it in turns!

Channels which are not in use are indicated by Free.
If you are a club member and missing from this list please e-mail the website with your name and channel number.

2.4 GHz Radio Systems

OFCOM have issued the necessary permissions and changes to Government legislation which allow the sale and use of approved equipment transmitting on the 2.4 GHz band at 100mw maximum radiating power in  December 2006.

Equipment on this band is already selling in large numbers and will soon start to appear at the club field or flying event.  At this early stage only one manufacturer (Spektrum) is offering equipment on this frequency, however indications are that more will take advantage of this new technology in the near future.   

Below are a few points for your guidance on operation and integration within your normal flying activities, however always remember the final decision on any matter relating to the safety of a flight rests with the pilot.
