There has been a lot of discussion about regulatory compliance on the announcement thread for these radios.
I thought I should explain a bit about why these radios don't already have compliance certificates, and what you can do to get involved in an effort to get them certified. I should first note that I don't work for 3DRobotics - I'm just a volunteer ArduPilot developer who happens to be very interested in these radios. I also wrote most of the radio firmware. So this is not an official 3DRobotics statement.
The basic idea with regards to regulatory compliance is that these are DIY radio parts. It is our understanding that, at least in the US and Australia, it is quite OK to use radios that comply with the relevant standards without getting them officially certified. Other countries have different rules.
So why didn't 3DRobotics get them certified anyway? Part of the problem is that the firmware is being rapidly developed, with new features regularly added. Under some certification systems that may mean re-certifying each firmware. That would cost a lot, and push up the cost of the radios.
The second problem is that there are so many different certification systems. There is FCC in the US, C-Tick in Australia, CE in Europe etc etc. Sometimes it may be possible to get quicker/cheaper certification of one type if you already have another type, but it is still complex.
So what do you do if you want to use/distribute these radios in a way that requires certification? I think the only reasonable answer is for the community to solve the problem. If someone puts their hand up to volunteer to do the legwork to get these radios certified in some area then they could share the results here and hopefully make life easier for someone else to work on certification elsewhere.
Meanwhile, if you post something about certification, please try to make sure you do your research carefully to make sure the information is accurate. If we can build a community effort around this then I think we can solve it together.
