G'Day all,On checking some legislation for entry to the 2009 Outback Challenge I noticed that ACMA are amending class license 2000 to specifically exclude the use of video under the provision for telemetry transmitters. (OSD telemetry)The reasoning given doesn't make any logical sense to me, I'd appreciate a review by one of you more technically savvy DIY Droners on the validity of the reason for the change. Quoted below-Quote - Telecommand transmitters are used to transmit signals to initiate, modify or terminate functions of equipment at a distance. Telemetry transmitters are used to automatically indicate or record measurements at a distance from the measuring instrument. To prevent interference with other devices telecommand and telemetry transmitters operating under the LIPD Class Licence must not exceed EIRP limits as outlined in items 25, 26 and 27.Telemetry transmitter classes should not be used as high power video senders, nor can higher power telecommand channels be used for transmitting computer programs. To carry out such activities would require a breach of the maximum EIRP limits stated. ACMA therefore proposes to include a limitation on the use of telemetry and telecommand transmitters, to prevent the use of these items for sending video or software downloading. - End QuoteWhy would transmission of video require a breach of the specified EIRP power of 1W?In my view ACMA shouldn't be making rules for the sake of it and should have a reason for the modification. If there have been real interference issues I'm sure they won't mind producing the reports.Aust based FPV flyers feel free to review the change at http://www.acma.gov.au/WEB/STANDARD/pc=PC_311727 and send your comments to - regulatorydevelopment@acma.gov.auSUBMISSIONS ON THE CHANGE CLOSE 15 JUN 09
