FCC Technician Exam Question Of The Day (T2B07)

Q) What should you do if you receive a report that your station’s transmissions are causing splatter or interference on nearby frequencies?

A) Check your transmitter for off-frequency operation or spurious emissions

NJ2X Notes:
"Splatter" on SSB transmissions is high-order intermodulation distortion (IMD) caused by gross overdriving.  A transmitter will generate IMD if it is driven too hard.  It is important to make sure that overdriving never happens with your transmitter or amplifier.
