There are a lot of chinese produced transmitters being brought into the country and sold on sites like TradeMe.

Not all of these units meet RSM regulations in terms of compliance.

Below are the units identified so far which do not comply. More will be added as we become aware of them.







There are several issues with these units.

1) The power is adjustable from outside the case. This contravenes Schedule 1, para. (5) of the Radiocommunications Regulations (General User Licence for Low Power FM Broadcasting) Notice 2010.

2) Many of them have poor or no output filtering, which means they transmit harmonics which can interfere with other services including aviation = really, really BAD.

If you purchase one of these units and RSM become aware that you are using it on the air, you may be liable to a fine, confiscation of the equipment or both.

It is highly recommended that you find something better to use for your station.
