|Recommendations for Transmitter Frequency Control|
Co-ordinated by Graham Stanley (you can PM Graham from the forum)
As users of this website often attend events at many different location, it is apparent a common frequency control process assists in reducing accidental misuse of the 35mHz channels available.
The most common process (and thus the recommended standard) is as follows:-
The organisers of events book pilots and their transmitters in before flying commences. Adminitration, such as proof of insurance and qualifications (i.e. current BMFA / LMA card / model exeption certificate etc) should be requested, and any fees collected prior to the next steps. Fliers in the transmitter control log should be grouped together by their transmitter frequency so it is clear if more than one pilot wishes to use a given frequency.
The organisers provide a pegboard, with pegs numbered for each of the frequencies. The board has a numbered space for each peg, and a hook adjacent to each numbered space.
Before a pilot can switch on his transmitter:-
After the flight is complete, model recovered and switched off etc. the transmitter must be switched off, and the peg may be returned to the pegboard so another pilot may use that frequency if required. As the peg is placed back on the pegboard the ID tag is removed by the pilot. If the pilot is the sole user of this frequency (as confirmed by the transmitter control log created above) he may retain the peg for a more extended period, but ensure it is returned at the end of the flying session.
Tug pilots are often given priority of use of a given channel, so advance sight of the published user frequencies and ensuring your choice is logged on the list can increase flying time available. See the list (add link to the list)
Should a pilot change the frequency in use, the transmitter must be booked in again at the Tx control with a check of actual transmitted frequency (at reduced power or minimum aerial and, of course with the requisite peg(s) not currently in use) BEFORE use..
One other consideration for the pegboard custodian is that, although nobody will do it deliberately, pegs will inadvertently be taken off-site and could turn up at the next meeting. When a replacement peg is put on the board, all pegs should be marked in such a way that 'rogue' pegs can be easily spotted in future.
At events attended by the public the organisers might further tighten the above by imposing a transmitter pound, booking in and out transmitters so that unused transmitters are not available to be accidently switched on in error.
