> spurious emissions. The updated language imposes a slightly higher
> standard on newer transmitters or amplifiers of any power level. Starting
> June 1, the rule will provide that:
>
>     * the mean power of any spurious emission from HF transmitters or
> external RF power amplifiers installed after January 1, 2003, must be at
> least 43 dB below the mean power of the fundamental emission.

> not exceed 50 mW and must be at least 40 dB below the mean power of the
> fundamental emission. If the mean power output of such as transmitter is
> less than 5 W, the attenuation must be at least 30 dB.

> Still exempt from the provisions of §97.307(d) are transmitters built
