Your SSB transmitter is set to operate lower sideband at 7100 kHz. With a single 1000 Hz tone as modulation, at which frequency is RF transmitted?

In Single Sideband (SSB) transmission, the actual radio frequency transmitted is the mathematical sum or difference of the carrier frequency and the modulating audio frequency. When operating on Lower Sideband (LSB), the transmitted signal is located below the suppressed carrier frequency. To find the exact transmitted frequency, subtract the audio tone frequency from the carrier frequency. First, convert the 1000 Hz tone to kilohertz (kHz) so the units match: 1000 Hz equals 1 kHz. Then, subtract this 1 kHz from the 7100 kHz carrier. The calculation is 7100 kHz - 1 kHz = 7099 kHz. If the transmitter had been set to Upper Sideband (USB), you would add the frequencies instead, resulting in 7101 kHz. Subtracting 1000 kHz instead of 1000 Hz leads to the incorrect distractor of 6100 kHz.
