Which is an indication of proper operation of a SSB transmitter rated at 60 watt PEP output?

The correct indication of proper operation of a Single Sideband (SSB) transmitter rated at 60 watts Peak Envelope Power (PEP) is demonstrated when speaking into the microphone causes the power meter to fluctuate around 60 watts. This fluctuation reflects the modulation of the voice signal, which is characteristic of SSB operation. In this mode, the transmitter is designed to amplify the audio signal from your voice, allowing the output power to vary with the amplitude of the audio being transmitted.

When engaged in voice communication through SSB, the power output is not static. It varies depending on how loudly or softly you speak, leading to fluctuations in the reading on the power meter. A proper functioning SSB transmitter will demonstrate this behavior when you modulate your voice into the microphone, confirming that the transmitter is effectively responding to the audio input.

The other options indicate problems or misconceptions about SSB operation. An indication of power output when keyed without speaking does not provide a legitimate measure of transmitter performance, as legitimate operation relies on audio modulation. Regular fluctuations from zero to 60 watts in SITOR communications instead point to issues with signal consistency and are not representative of a stable SSB usage. A steady indication on the RF power meter shows no fluctuation while speaking
