What is the second harmonic of an SSB frequency of 4146 kHz?

Harmonics are whole-number multiples of a fundamental frequency, and the second harmonic is twice the base frequency. So if the SSB frequency is 4146 kHz, doubling gives 8292 kHz. The other numbers don’t fit because 4.146 kHz is the base scaled down, 2073 kHz is half of 4146 kHz, and 12438 kHz is three times the base. Thus 8292 kHz is the second harmonic.
