Radio Transmitter & Receiver Usage

  NEW MEMBERS - Don't buy anything until you come to the club and get advise from a senior club member. 

At the Bulleen field, radio control transmitters on the following frequencies are allowed:

                          # MAAA MOP's can be found here

No transmitter will be acceptable or allowed to be used unless it has been radio frequency certified (excluding 2.4GHz) by an independent authority, and displays the appropriate certification sticker.  Radio Frequency Certification must be current (within the past two years).  The list of current testers and more information can be found on the VMAA website here.

Also it is a good idea for new club members before purchasing any radio equipment to visit DAC and talk about what equipment best suits your requirements.  Especially if you are considering the 36MHz band and what channels are heavily in use to avoid.

2.4GHz Transmitter & Receiver Equipment

Your Committee has reviewed its decision regarding the use of 2.4GHz equipment (Transmitter & Receivers) and has agreed to certain 2.4GHz equipment being used at DAC. This approval is subject to the following conditions.

1.    The 2.4GHz transmitters and receivers must be used in accordance with the MAAA 2.4GHz Equipment Policy MOP058. This is on the MAAA website and a copy has been placed in the Clubhouse for your convenience. READ IT BEFORE COMMITTING TO PURCHASING OR THE USE OF 2.4GHz EQUIPMENT.

2.    Only Equipment approved by the MAAA can be used with the exception if the equipment is generally regarded as being only suitable for “Park Flyers” CANNOT be used at DAC, including receivers.  Example Spectrum transmitter using DSM technology.

3.    Only the equipment that the committee has approved have affixed to the equipment either the C-Tick , FCC  or ETSI compliance marking that identifies that it meets the specific required standard, can be used.

4.    Equipment must be installed and “range checked” in accordance with the manufacturer’s instructions and consistent with safe modelling practices.

5.    Frequency Keys MUST be used to ensure that no more than ten 2.4GHz transmitters are in use at any time. 

6.    This approval is subject to ongoing review and, should any safety issues arise, this approval to operate 2.4GHz equipment at DAC can be suspended or removed at any time.

7.    Members should note that cameras and other devices transmitting on 2.4GHz are now available. These MUST NOT be used at DAC.

8.    2.4GHz equipment must be capable of doing a ground range check, required before the first flight of a new or repaired model.

NOTES - 2.4GHz Transmitter & Receiver Equipment

• 2.4GHz equipment refers to the "whole communication system" - transmitter, receiver, antennas, installation and usage.

• The maximum output power levels specified in the ACMA C-Tick , the FCC  and the ETSI  Standards vary. Generally ETSI standards specify lower maximum output powers. Whilst most equipment currently on the market have power levels lower than the maximum allowed under ACMA and FCC Standards, users should be aware that equipment that complies with the ETSI Standards may have a lower power output than the equivalent product complying with the other Standards. If this is the case then they will give reliable operation only to a reduced range. Users of equipment marked as complying with the ETSI Standard need to be aware of this possibility.  If the equipment is regarded as only suitable for “Park Flyers” then it CANNOT be used at DAC.

• This equipment is generally regarded as “line of sight” and people, trees and buildings between pilot and plane may cause interference, as may fog, cloud and high humidity.

• This technology continues to evolve and new equipment may come on to the market before it has been approved by the MAAA or DAC. Be aware before purchasing that such equipment may not be approved at DAC.

• The committee retains the right to request inspection of radio equipment and if the equipment is found to not comply with the above, or if an inspection request by a committee member is refused, then that equipment cannot be used at DAC.

• Whilst this technology may remove the problems of frequency clashes, all pilots are required to fairly share air time.

Refer any queries to the DAC Committee members.
