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.

CZH-5C



CZH-10A




CZH-15A






SDA-15B





ST-15B



ST-7A




The issue with these units is 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.

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.

If you have one of these, or wish to purchase one, you must have the unit modified so the power output cannot be increased above the maximum allowable EIRP based on your installation, cable loss, antenna gain etc.
