Frequency Channel Availability

Radio frequency control is paramount in any r/c club, and we operate a "peg off" system to ensure there are no conflicts. 

This is the system we use for transmitter frequency control.  Each of the 36 channels is allocated a peg that is normally clipped to the frequency board.  Both the peg and board are marked with the frequency channel number.  Before switching on their transmitter, each member must take their corresponding peg from the board and keep it whilst "live".  If the peg is not on the board the channel is already taken and your transmitter must not be switched on until the peg has been returned.

The consequences of two people operating on the same channel are that both pilots will lose control of their models as soon as the second transmitter is switched on.  Obviously this is an extremely dangerous situation which must be avoided.  

Essentially, without the peg, you can't operate your radio.

With the introduction of the Spectrum technology, the peg system is not required.
