  Yes certain types of transmitters are used for 3G on this band, HOWEVER Frequency hopping transmitters may be used between the frequencies of 915-928 up to 1W of power as long as at least 20 hopping frequencies are used. Both the 3DR radios and the RFD900's fall into this category.

  this is outlined in article 52 in this Gov regulation document: http://www.comlaw.gov.au/Details/F2011C00543

  which is why companies selling items such as this can claim it can be used license free in Australia:

  Whereas the only provisioned use of 433mhz is up to the power of 25mW for any type of transmitter unless you hold an amateur radio license.

  915MHz is used for the 3G phone network in Australia. It has no legal threshold and you will get fined if you get caught. 433MHz is mixed use with threshold restrictions and is legal for this kind if stuff. 433Mhz has better qualities for telemetry.

  Can't wait to try out a set of RFD900+'s!

  The 915mhz used by these radios is 100% because it falls under frequency hopping. Totally different than standard 915Mhz band (ie 915Mhz cannot be used for FPV while it is fine for a frequency hopping data link). Can link the regulation article for reference if anyone wants clarification.

  Yeah use the 3dr 915 on the iris+ and the rfd900 on my planes both work really well.

  915 is the way to go. You can only legally use 433 up to about 25mw but 915 in these types of frequency hopping radios can be used up to 1W without a license. The 3DR radios are only 100mw but it means you can use it at full power without worry.

  Hello everyone, 

  I'm planning on ordering the Iris+. What frequency do I need to choose? 915 MHz or the 433 MHz?

  Thanks.

  Does anybody know of any UAS manufacturers in Australia, preferably WA.
  
  We are looking for a company to build us a UAS (multirotor/groundstation etc.) that will give us the capability to do mapping/photogrammetry, and remote inspections in the mining and construction industry.
  
  We are a small start up at the moment, so a modest budget is what we have to start with right now, so we were thinking about something like a tarot hex frame, with big props/motors, and pixhawk as the flight controller.
  
  Personally I have experience in building/flying/crashing quads over the last 2 years, and I could definitely build this platform myself, but we want a professional looking system to represent our professional outfit.
  
  We are currently going through the certification process, and would expect to be complete by the end of this year, so training on a new system is required in the very near future.
  
  Please PM me with details.

  Hello, 

  My name is Jesús from Spain, I´m not in Australia yet but I´m going to go for Phd stay at the Sydney University at the ACFL for two months in august . And i I want to contact with the UAV community there. 

    Thanks :-)

  Hi Lukaso,
  
  I'm potentially looking for part time development work but I'm Perth based unfortunately.
  
  PM if you want to know more.
  
  Thanks,
  Glenn
