I am just saying the original article in this post you mentioned the devices are illegal, this is not the case. They are legal as they are also available and approved for use in Australia.

They do not require special licences to use them.

My first post regarding the 434MHz being amateur et al might have given you the impression that I made a sweeping statement about useage of LIPDs - I am sure I did not mentioned that the LIPDs were illegal in Alistairsam's case; especially in subsequent posts what I said was that it is illegal to transmit in the amateur bands IF you are not licensed to do so and I also clarified that it being an LIPD device that it was anyway alright to do so without any need for a licence since the device is already class-licensed.

The other matters might be OT but it was only in response to the OP that I elucidated the matters that he queried about

Cheers

Anyway the only issue with these is the range which can be extended based on the antenna. One change I noticed is the EIRP is 25mW although in my days it was only 10mW. The range though with the right antenna can be as much as 1 km. I have tested this arrangement and still have the TX and RX here non modem version.

Spurious radiation is tested based on the appropriate standard. The AS compliance is related to the appropriate CE or EU standard and does not require re-testing. Not like telephones and general consumer equipment.

The LPRS equipment meets the standard very well, heavily shielded but the most problems that are experienced is other LIPD's around (garage door controllers) which use the same frequency and may reduce performance of the radio side. This at the moment is a rare occurance until the spectrum is flooded.
