  • 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.
  • Anyone interested in another sydney meetup? FPV racing ?

  • 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. 

  • Hi All,  selling m 3DR 2014 X8,  its done about 3 hrs since new if that. It has FPV kit,  3 Lipos, gimble.  Its listed here on gum tree.

Freelancing

Hi guys,I've been into drones for a few years as a hobby, and recently got a Mavic Pro.  I've posted a few pics & videos on my facebook & instagram, and I've been really surprised by the number of friends who've asked me to do work for their businesses.I work full time so droning is still a hobby, but I learn more everyday, and I reckon there have to be hundreds of others out there like me who'd like to make a bit of money on the side.So I've set up dronetaskr.com.au - it works like…
