Several radio bands are available to modellers to enable them to control their
models. This club uses the 35MHz band and now the newly available 2.4GHz band.
The 35MHz band 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 in the FACILITIES
section 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.
The 2.4GHz band is now being used by about half
of the club members,
and by a third of the members exclusively. This system enables fliers to to
operate without the need to check the frequency of other fliers on the same
field as the system ensures that unique frequencies are allocated. It should be
noted, however, that there are some problems regarding the range of this
system and it is vital that the correct receivers are used if you are flying, say,
thermal gliders at extreme distances. It is also recommended that a peg
indicating use of 2.4GHz is placed on the pegboard to show who is using this
band.
Because the club has two fields, it
is essential when using 35MHz
that only channels up to 70 are
used at Boldon and channels 72
and above are used at Chuter
Ede.
