MODEL AIRCRAFT CLUB
RADIO FREQUENCIES
13th.November 2001- amended (one each channels 55 and 66 added)
10th.June 2001- Frequency list updated (list provided by John Raine).
This page will be used to:
Explain the radio system used by the club for the control of model aircraft
List the numbers of members currently using each of the available channels
Notify members of the availability of crystals for the ten new channels recently made available.
Several radio bands are available to modellers to enable them to control their models. This club uses only the 35MHz band which currently consists of thirty six channels, numbered from 55 to 90. These are separated from each other by a 10KHz. spacing and if correctly used (i.e. using the correct crystals in transmitter and receiver) it is in order to operate on an adjacent channel to a flyer on the same field (but see the recommendations regarding a periodic adjacent channel check in the BMFA members handbook, Millenium Edition, page 14).
It is not of course possible to operate on the same channel (see the club rules dealing with conduct on the flying field). In order to enable members to have a good chance of flying, it is wise to have more than one set of crystals. In order to improve this chance a list of the number of members currently owning crystals for each channel is shown below. It is hoped to keep this information up to date so that it will remain useful.
